+Commands to run da examples: 
+1a)Start web servers by either running 3 servers:
+cargo run --example web-server --profile=release-lto --features="full-ci" <PORT_FOR_CDN> 
+cargo run --example web-server --profile=release-lto --features="full-ci" <PORT_FOR_DA> 
+cargo run --example web-server --profile=release-lto --features="full-ci" <PORT_FOR_VIEW_SYNC> 
+
+1b)Or use multi-web-server to spin up all three:
+cargo run --example multi-web-server --profile=release-lto --features="full-ci" <PORT_FOR_CDN> <PORT_FOR_DA> <PORT_FOR_VIEW_SYNC> 
+
+2) Start orchestrator:
+cargo run --example web-server-da-orchestrator --features="full-ci,channel-async-std" --profile=release-lto -- <ORCHESTRATOR_ADDR> <ORCHESTRATOR_PORT> <ORCHESTRATOR_CONFIG_FILE> 
+
+3a) Start validator:
+cargo run --profile=release-lto --example web-server-da-validator --features="full-ci" <ORCHESTRATOR_ADDR> <ORCHESTRATOR_PORT>
+
+3b) Or start multiple validators:
+cargo run --profile=release-lto --example multi-validator --features="full-ci" <NUM_VALIDATORS> <ORCHESTRATOR_ADDR> <ORCHESTRATOR_PORT>
+
+I.e. 
+cargo run --example web-server --profile=release-lto --features="full-ci" 9000 
+cargo run --example web-server --profile=release-lto --features="full-ci" 9001 
+cargo run --example web-server --profile=release-lto --features="full-ci" 9002
+cargo run --example web-server-da-orchestrator --features="full-ci,channel-async-std" --profile=release-lto -- 0.0.0.0 4444 ./orchestrator/default-run-config.toml 
+cargo run --profile=release-lto --example web-server-da-validator --features="full-ci" 2 0.0.0.0 4444
+
+OR: 
+cargo run --example multi-web-server --profile=release-lto --features="full-ci" 9000 9001 9002
+cargo run --example web-server-da-orchestrator --features="full-ci,channel-async-std" --profile=release-lto -- 0.0.0.0 4444 ./orchestrator/default-run-config.toml

+# USAGE
+
+Networking library inteded for use with HotShot. Builds upon abstractions from libp2p-rs.
+
+## CLI Demo
+
+To get very verbose logging:
+
+```bash
+RUST_LOG_OUTPUT=OUTFILE RUST_LOG="trace" cargo run --features=async-std-executor --release
+```
+
+The idea here is to spin up several nodes in a p2p network. These nodes can share messages with each other.
+
+```
+nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- -p 1111"
+nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/1111/quic-v1 -p 2222"
+nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/2222/quic-v1 -p 3333"
+nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/3333/quic-v1 -p 4444"
+nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/4444/quic-v1 -p 5555"
+nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/5555/quic-v1 -p 6666"
+nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/6666/quic-v1 -p 7777"
+nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/7777/quic-v1 -p 8888"
+nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/8888/quic-v1 -p 9999"
+```
+
+At this point the idea is that each node will continue to attempt to connect to nodes
+until it hits at least 5 peers.
+
+Use `Tab` to switch between messages and prompt. Press `Enter` to broadcast a message to all connected nodes.
+Press `Right Arrow` to direct-send a message to a randomly selected peer.
+Press `q` to quit the program from the messages view.
+
+## Counter Single Machine Tests
+
+Each node has its own counter. The idea behind these tests is to support "broadcast" messages and "direct" messages to increment each nodes counter.
+
+`cargo test --features=async-std-executor --release stress`
+
+spawns off five integration tests.
+
+- Two that uses gossipsub to broadcast a counter increment from one node to all other nodes
+- Two where one node increments its counter, then direct messages all nodes to increment their counters
+- One that intersperses both broadcast and increments.
+- One that intersperses both broadcast and increments.
+- Two that publishes entries to the DHT and checks that other nodes can access these entries.
+
+This can fail on MacOS (and linux) due to ["too many open files."](https://github.com/EspressoSystems/hotshot-networking-demo/issues/18) The fix is:
+
+```bash
+ulimit -n 4096
+```
+
+## Counter Multi-machine tests
+
+In these tests, there are three types of nodes. `Regular` nodes that limit the number of incoming connections, `Bootstrap` nodes that allow all connections, and `Conductor` nodes that all nodes (bootstrap and regular) connect to and periodically ping with their state. This "conductor" node instructs nodes in the swarm to increment their state either via broadcast or direct messages in the same fashion as the single machine tests.
+
+In the direct message case, the conductor will increment the state of a randomly chosen node, `i`. Then the conductor will direct message all other nodes to request node `i`'s counter and increment their counter to the value in `i`'s node. In the broadcast case, the conductor will increment the state of a randomly chose node, `i`, and tell `i` to broadcast this incremented state.
+
+In both cases, the test terminates as successful when the conductor receives the incremented state from all other nodes. Then, the conductor sends a special "kill" message to all known nodes and waits for them to disconnect.
+
+Metadata about the toplogy is currently read from an `identity_mapping.json` file that manually labels the type of node (bootstrap, regular, conductor). The conductor uses this to figure out information about all nodes in the network. The regular nodes use this to learn about their ip address and the addresses necessary to bootstrap onto the network. The boostrap nodes only use this to learn about their ip addresses.
+
+### Running counter multi-machine tests
+
+A sample invocation locally:
+
+```bash
+# run each line in a separate terminal
+nix develop -c cargo run --features webui,async-std-executor  --release --example counter -- --bound_addr 127.0.0.1:9000 --node_type Bootstrap --num_nodes 5 --bootstrap 127.0.0.1:9000 --webui 127.0.0.1:8000
+nix develop -c cargo run --features webui,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9001 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --webui 127.0.0.1:8001
+nix develop -c cargo run --features webui,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9002 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --webui 127.0.0.1:8002
+nix develop -c cargo run --features webui,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9003 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --webui 127.0.0.1:8003
+nix develop -c cargo run --features webui,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9004 --node_type Conductor --num_nodes 5 --bootstrap 127.0.0.1:9000 --webui 127.0.0.1:8004
+```
+
+### Network Emulation
+One may introduce simulated network latency via the network emulationn queueing discipline. This is implemented in two ways: on what is assumed to be a AWS EC2 instance, and in a docker container. Example usage on AWS EC2 instance:
+
+```bash
+# run each line in a separate AWS instance
+nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9000 --node_type Bootstrap --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Metal
+nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9001 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Metal
+nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9002 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Metal
+nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9003 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Metal
+nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9004 --node_type Conductor --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Metal
+```
+
+And on docker:
+
+```bash
+# run each line in a separate Docker container instance
+nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9000 --node_type Bootstrap --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Docker
+nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9001 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Docker
+nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9002 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Docker
+nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9003 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Docker
+nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9004 --node_type Conductor --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Docker
+```
+
+On an AWS instance, a separate network namespace is created and connected to `ens5` via a network bridge, and a netem qdisc is introduced to the veth interface in the namespace. Within a docker container, a netem qdisc is added on interface `eth0`.
+
+### Network Emulation Dockerfile
+
+Usage:
+
+```
+docker build . -t libp2p-networking
+# expose ports
+docker run -P 8000:8000 -P 9000:9000 libp2p-networking
+```

+# Orchestrator
+
+This crate implements an orchestrator that coordinates starting the network with a particular configuration.  It is useful for testing and benchmarking.  Like the web server, the orchestrator is built using [Tide Disco](https://github.com/EspressoSystems/tide-disco).  
+
+To run the orchestrator for a libp2p network: `cargo run --example libp2p-orchestrator --features="full-ci,channel-async-std" 0.0.0.0 3333 ./orchestrator/default-libp2p-run-config.toml `

+HotShot uses an event-based architecture.  This architecture is made of 4 main tasks: Network Task, View Sync Task, Consensus Task, and DA Task.  The Network Task handles all incoming and outgoing messages.  It forwards incoming messages to the correct task and listens for outgoing messages from the other tasks.  The View Sync Task coordinates the view sync protocol.  It listens for timeout events from the Consensus Task.  Once a certain threshold of timeouts seen has been reached, the View Sync Task starts the View Sync protocol to bring the network back into agreement on which view it should be in. The Consensus Task handles the core HotShot consensus logic.  It manages replicas that listen for quourm propsoals and vote on them, leaders who send quorum proposals, and next leaders who listen for quorum votes and form QCs.  The DA task handles the data availability protocol of HotShot.  It listens for DA proposals, sends DA proposals, and forms a Data Availability Certificate (DAC)
+
+A diagram of how events interact with each task is below:

+# Web Server
+
+This crate implements a web server that HotShot can use to increase its throughput.  The web server is designed to be run behind several Nginx instances for high performance.  
+
+The run the web server: `cargo run --features=full-ci --example web_server`.  
+This will start the web server at `0.0.0.0:9000`
+
+## How it works
+Unlike the other networking implementations in `HotShot` that use a *pushing* paradigm over a TCP connection, the web server uses a *pulling* paradigm over HTTP.  In the older centralized server, for example, messages are pushed to nodes from the server.  In contrast, in the web server nodes must poll (pull from) the server periodically to download the latest data.  The direction of dataflow is reversed.  This design allows us to take advantage of Nginx's powerful caching mode, which will improve performance in the large networks `HotShot` is designed for.  Keep in mind that `HotShot` will also be using `Libp2p` in tandem with the web server.  The web server allows high bandwidth through the network under optimistic conditions while `Libp2p` protects against centralization and censorship.  
+
+The web server is built on [Tide Disco](https://github.com/EspressoSystems/tide-disco), an expansion on the popular [Tide](https://docs.rs/tide/0.16.0/tide/index.html) Rust web application framework.  It has several endpoints specified in its `api.toml` file.  These endpoints are what nodes use to either POST or GET messages.  For example, a replica node will poll the web server periodically through the `proposal` endpoint to ask if there is a proposal for its current view.  The server will respond with either an error if there is no proposal for that view yet, or with the proposal.  It works similarly for transactions: Nodes can post transactions to the web server at any time.  They can also download all the transactions they haven't received yet from the web server.

 Commands to run da examples: 
 1a)Start web servers by either running 3 servers:
-cargo run --example web-server --profile=release-lto --features="full-ci" <PORT_FOR_CDN> 
-cargo run --example web-server --profile=release-lto --features="full-ci" <PORT_FOR_DA>

+just async_std example web-server -- <PORT_FOR_DA> 
+just async_std example web-server -- <PORT_FOR_VIEW_SYNC> 
 
 1b)Or use multi-web-server to spin up all three:
-cargo run --example multi-web-server --profile=release-lto --features="full-ci" <PORT_FOR_CDN> <PORT_FOR_DA> <PORT_FOR_VIEW_SYNC> 
+just async_std example multi-web-server -- <PORT_FOR_CDN> <PORT_FOR_DA> <PORT_FOR_VIEW_SYNC> 
 
 2) Start orchestrator:
-cargo run --example web-server-da-orchestrator --features="full-ci,channel-async-std" --profile=release-lto -- <ORCHESTRATOR_ADDR> <ORCHESTRATOR_PORT> <ORCHESTRATOR_CONFIG_FILE> 
+just async_std example web-server-da-orchestrator -- <ORCHESTRATOR_ADDR> <ORCHESTRATOR_PORT> <ORCHESTRATOR_CONFIG_FILE>

+just async_std example multi-validator -- <NUM_VALIDATORS> <ORCHESTRATOR_ADDR> <ORCHESTRATOR_PORT>
 
 I.e. 
-cargo run --example web-server --profile=release-lto --features="full-ci" 9000 
-cargo run --example web-server --profile=release-lto --features="full-ci" 9001

* message type Vid (unimplemented) -> VidDisperse (now implemented)

* VidCert message type

* restore original test timeout durations, #1713 now fixed

* type: VidCert use cert route

* more time for tests to complete

* [no ci] more comment links to github issues

* [no ci] comment link to #1717

* add commented VID test code

* close #1697, fix test with VID

* make_vote_token failure should cause test to fail

* fix #1717

* add ASYNC_STD_THREAD_COUNT=1 to test_success, test_web_server, test_consensus_task

Subject: [PATCH 0126/1393] chore: remove Committable from 3 more types (#1789)

* VoteMap type param Commitment<C> -> COMMITMENT

* VoteAccumulator type param commitment instead of Committable

* VoteType remove Committable from type param (this was a big one)

Subject: [PATCH 0157/1393] chore: Remove Committable for more types, use
 CommitmentBounds (#1812)

* remove Committable from VoteMetaData type param

* remove Committable from VoteToken

* remove Committable from ConsensusExchange::Commitment assoc type (whoa that's big)

* update commit package (for Send, Sync on Commitment)

* WIP remove Committable from QuorumCertificate. there's a circular dependency QuorumCertificate -> SignedCertificate::Vote -> QuorumVote -> YesOrNoVote -> QuorumCertificate so remove Committable from all those, too. need an alternative to fake_commitment in order to proceed

* use latest 'commit' for default_commitment_no_preimage()

* lint, remove unneeded pub

* fix merge bug, tests pass locally with lots of error logs

* lint

* use CommitmentBounds everywhere, fix ensuing build breaks

* cargo fmt why didn't it run automatically for me?

* lint again grrrrrrrrr

Subject: [PATCH 0201/1393] fix: Transaction task use quorum exchange instead
 of committee exchange (#1864)

* tidy code TODO comments

* comments

* don't re-hash block commitment

* more comments

* add sign_block_commitment method to QuorumExchangeType trait

* TransactionTaskState change committee_exchange -> quorum_exchange then fix all the build breaks

* add test_memory_network

* get num_storage_nodes from quorum exchange membership

* update comment github issue link

* lint

* address https://github.com/EspressoSystems/HotShot/pull/1864#pullrequestreview-1660806880

Subject: [PATCH 0494/1393] #2059: Organize non-prod code (#2134)

* Move example/test implementations to hotshot_testing

Closes #2059

* Warn when using demo impls in production builds

* Refactor demo/test types

Collapsed three virtually identical `NodeType` implementations into one,
split code from `testing::demo` into more descriptive modules and
renamed various test types to conform to a single naming scheme.

* Remove 'demo' features

Those weren't actually gating anything anymore

Subject: [PATCH 0513/1393] Remove ConsensusApi & HotShotType (#2166)

* Remove ConsensusApi & HotShotType

Closes #1194

Those traits had only one implementor each at this point,
all used implementations moved to `impl`s for corresponding types.
Renamed `ConsensusSharedApi` to `ConsensusApi`.

Subject: [PATCH 0775/1393] Speed Up DHT Retrieval (#2555)

* Only wait for required number of records

* Lower timeout and lint

* more linting/remove `post_identity` from ochestrator

* fix webserver

* Always Remove query when it's completed

* spanw a task for cache set

* Actually block again

* block

* give a little more time for libp2p

* clone the cache and spawn task for insert

Subject: [PATCH 0776/1393] [CX_CLEANUP] Integrate new `Task`, in the code and
 remove the old (#2493)

* lint up to missing docs in task-impls

* All builds but the tests~

* All builds but the tests in testing

* linting

* Test can run, but they fail

* some fixes

* cargo fix

* replace broadcast with broadcast_direct

* test almost running correctly, maybe not passing

* Add Tasks to project, success test passes

* test can pass

* fixing tests, basic passes except unit tests

* fixed consensus task test

* fixing other task tests

* Remove more cruft

* replace event sending with helper for better errors

* lint after merge

* fixing unit tests and lints for both async types

* remove superfluous log and fix doc

* Remove Cargo.lock from tasks

* cleanup

* Addressing comments

* Update tasks based on feedback

* remove outdated # Panics doc comments

* missed on # Panics

* Reveiw comments minus filters

* Lower a log level, fix task/cargo.toml

* Remove todo

Subject: [PATCH 0804/1393] Unify HotShotConsensusApi into SystemContext
 (#2601)

`HotShotConsensusApi` is now merged into `SystemContextHandle`. The `SystemContext` wrapper was removed, and `SystemContextInner` was renamed to `SystemContext`. `SystemContextHandle` now directly contains an `Arc<SystemContext>` without an intermediate wrapper.

A `CreateTaskState` trait is introduced for initialization of most HotShot tasks.

Subject: [PATCH 0806/1393] Adds DA committee broadcast TransmitType (#2616)

* Adds DA committee broadcast TransmitType

* adds TransmitType::DACommitteeBroadcast

* memory and web impl just forward to broadcast_message

* libp2p sends direct messages to DA Committee members

* Send direct messages to DA committee members in parallel

* Use into_iter on BTreeSet in da_broadcast_message

Subject: [PATCH 0819/1393] Clean up header genesis (#2668)

Previously, `Header::genesis` was required to also return a payload
and metadata. This is redundant, because we also have `Payload::genesis`.
In addition, `Header::genesis` was expected to compute a genesis VID
commitment, since a VID commitment is required to construct a header.
This breaks abstraction, since in all other cases only HotShot computes
VID stuff, never the application. It is also error prone: I am adding a
feature to the query service to handle the genesis VID case, where we
don't receive VID data from HotShot. This feature requires that the
genesis VID is computed uniformly regardless of the application. Currently,
we use 8 storage nodes for this commitment in the HotShot example types
(quite arbitrarily) and 1 in the sequencer types. This change standardizes
the computation of the genesis VID commitment.

Subject: [PATCH 0820/1393] chore: proper VidScheme constructor (#2670)

* hello-world vid_scheme constructor

* WIP comments for later

* switch to newtype to hide impl details of VidScheme

* replace types::data::VidScheme -> types::vid::VidSchemeType

* clippy pacification

* move VidCommitment from data.rs to vid.rs

* new type aliases VidCommon, VidShare

* fix downstream build warnings (our CI should check non-test builds too)

* tidy comments and code

* lint pacification

* delete test_srs, move its body to vid_scheme

* rename {Namespace|Transaction}ProofType -> {Large|Small}RangeProofType

* use lazy_static for KZG SRS

Subject: [PATCH 0828/1393] Add tests for the upgrade task (#2642)

* Adds stronger testing harness

* Adds an iterator to generate test data for views

* Adds a test to validate that consensus correctly updates its internal state when receiving an UpgradeCertificate

* Correctly a mistake in consensus logic that took the UpgradeCertificate from the received QuourmProposal rather than the decided leaf.

Subject: [PATCH 0831/1393] Add timestamp to `TestBlockHeader` (#2696)

This is extremely useful for downstream testing. For example, many
tests in the query service rely on a timestamp. Without this change,
we would have to implement our own test types or implement something
very unrealistic (like always getting the current time every time we
get the timestamp for the same header).

This is also pretty realistic, as any real application will probably
timestamp its blocks, and it demonstrates getting inputs in `Header::new`
from the outside world (ie the hardware clock) in addition to just the
inputs which are passed in, which is good for example purposes.

* Use less verbose `impl Trait` as parameter

* Run all cancel tasks at the same time

* There can be multiple delayed tasks per given view

+```
 
 3a) Start validator:
+```

+```
 
 3b) Or start multiple validators:
+```
 just async_std example multi-validator-webserver -- <NUM_VALIDATORS> <ORCHESTRATOR_URL> <ORCHESTRATOR_PORT>
+```
 
 I.e. 
+```

 `just async_std example all-webserver -- --config_file ./crates/orchestrator/run-config.toml --orchestrator_url http://localhost:4444`
+
 For other argument setting, checkout `read_orchestrator_initialization_config` in `crates/examples/infra/mod.rs`.
+
 One example is: `just async_std example all-webserver -- --config_file ./crates/orchestrator/run-config.toml --total_nodes 15`.

-//! The [`Metrics`] trait is used to collect information from multiple components in the entire system.
-//!
-//! This trait can be used to spawn the following traits:
-//! - [`Counter`]: an ever-increasing value (example usage: total bytes send/received)
-//! - [`Gauge`]: a value that store the latest value, and can go up and down (example usage: amount of users logged in)
-//! - [`Histogram`]: stores multiple float values based for a graph (example usage: CPU %)
-//! - [`Label`]: Stores the last string (example usage: current version, network online/offline)

+///
+/// Usage:
+///
+///   `test_scripts[inputs, script1, script2, ...]`
+///
+/// The generated test will:
+///   - take the first entry of `inputs`, which should be a `Vec<HotShotEvent<TYPES>>`,
+///   - feed this to each task in order, validating any output received before moving on to the next one,
+///   - repeat the previous steps, with the aggregated outputs received from all tasks used as the new input set,
+///   - repeat until no more output has been generated by any task, and finally
+///   - proceed to the next entry of inputs.
+///
+/// # Panics
+///
+/// The macro panics if the input stream cannot be parsed.
+/// The test will panic if the any of the scripts has a different number of stages from the input.

Subject: [PATCH 0857/1393] Make CombinedNetworks delay duration configurable
 (#2726)

* Make CombinedNetworks delay duration configurable

* Secondary network delay configurable in HotShotConfig

* Rename CombinedConfig to CombinedNetworkConfig

* Network delay in test network generator

`secondary_network_delay` removed from `HotShotConfig`
because it cannot easily be passed to the test network
generator.

* Temporary pinning to hotshot-types branch

TODO: switch to hotshot-types tag or main branch
before merging

* Pin to hotshot-types tag 0.1.2

* Remove files added back by mistake

Subject: [PATCH 0860/1393] [CX_CLEANUP] Remove Special Case for View 1 (#2752)

* Make CombinedNetworks delay duration configurable

* Secondary network delay configurable in HotShotConfig

* Rename CombinedConfig to CombinedNetworkConfig

* Network delay in test network generator

`secondary_network_delay` removed from `HotShotConfig`
because it cannot easily be passed to the test network
generator.

* Remove special casing for view 1

* stricter checks for view

* Start with no vid commitment + fix test

* fix upgrade test

* fix proposal ordering tests

* move inject conensus to creation

* Temporary pinning to hotshot-types branch

TODO: switch to hotshot-types tag or main branch
before merging

* Update hotshot-types

* Pin to hotshot-types tag 0.1.2

* Remove files added back by mistake

* fix upgrade test

Subject: [PATCH 0862/1393] [STABILITY] - Remove Hack Fix in Vote Timeout
 Trigger (#2739)

* - Add support for View Sync Finalize Certificate 2 in consensus algorithm.
- Add implementation of the view sync certificate in consensus. Initiate a proposal when the event is received.

* Fix build by adding view_sync_cert to various locations.

* cargo fmt fix

* working on test

* approximately working test

* fix typo, clarify log

* remove old code

* clarify, remove typo

* satisfy clippy

* add voting logic

* clarify comment

* fix proposal call site, improve performance of cert check

* fix test, move cert check logic

* fix timeout cert check

* fix build

* fix vote test

* all tests passing, cleanup next

* fix calculation, remove old code

* fix versioning and fix build

* add todo comment, remove thread limit

* make doc builder happy

* fix comment, typos

* Potentially fixed off-by-one

* fix test runs

* more off-by-one fixes

* fix build

Subject: [PATCH 0866/1393] [NETWORK] Add Request Task (#2698)

* Don't lock channels

* cargo fix

* Allow killing the connected network handler

* Fix issues

* Remove State from NetworkNodeHandle

* Remove async where it's unused

* fix async std build

* Fix erros a little

* Starting VID request response

* handle network event

* Bubble up request/response

* Make Request and Response just bytes at network layer

* Adding to ConnectedNetwork

* Hooks for request/response in handle + trait

* fix request

* Remove request and response tasks for now

* update mod.rs

* Hooked up response flow to ConnectedNetwork

* Refactor interface to return result to caller

* Add request and response to message struct

* Clean up some message stuff

* Fix build error

* Hook up request and response fully

* Review myself, impl functions for combine

* Change Receiver interface to spawn task

* try_send instead of send

* Create the task for request handling

* rename request -> response

* fix lint

* clean up request response event handle fn

* fix build

* Comments and make the request signed

* add signature checking

* link gh issue

* Add Event for Validated Quorum Proposal

* Fix consensus task

* fix upgrade test

* start adding the task

* Fix the test...again

* progress

* Finish request task, modify vid disperse event

* Address comments

* fix build

* Make CombinedNetworks delay duration configurable

* Secondary network delay configurable in HotShotConfig

* Rename CombinedConfig to CombinedNetworkConfig

* Network delay in test network generator

`secondary_network_delay` removed from `HotShotConfig`
because it cannot easily be passed to the test network
generator.

* lock

* Temporary pinning to hotshot-types branch

TODO: switch to hotshot-types tag or main branch
before merging

* fixes

* Pin to hotshot-types tag 0.1.2

* Remove files added back by mistake

* fix build

* Remove whitespace

* Review comments

* fixes after main merge

Subject: [PATCH 0875/1393] Bring `hotshot-types` and `hs-builder-api` into
 `Hotshot` (#2812)

* WIP

* Still chasing a bug

* One down, one to go

* ... and done.

* Cleanup and finishing touches

* Fixing the post-merge code, and one missed issue in the pre-merge code.

* Some clarifying name changes.

* Removing bincode dependency where applicable

* cleanup of some (not quite all) remaining bincode invocations

* dependency versioning tags and cleanup

* bump version

* Bumping anticipated version

* Now with new VBS

* branch => tag on dependencies

* Update lock?

* Cargo.lock update

* Apparently `just * lint` runs with --features="hotshot-testing" enabled

* integrate new storage type

* fix build, tie up stragglers, modifying tasks next

* merge latest stable tabs

* merge latest tags and fix method signatures

* Update *-disco

* Dependencies updated to tags

* Add builder-api and types to repo

* fix doc

* hs-builder-api -> hotshot-builder-api

* fmt

Subject: [PATCH 0877/1393] [NETWORKING] Integrate Request and Response Tasks
 (#2717)

* Don't lock channels

* cargo fix

* Allow killing the connected network handler

* Fix issues

* Remove State from NetworkNodeHandle

* Remove async where it's unused

* fix async std build

* Fix erros a little

* Starting VID request response

* handle network event

* Bubble up request/response

* Make Request and Response just bytes at network layer

* Adding to ConnectedNetwork

* Hooks for request/response in handle + trait

* fix request

* Remove request and response tasks for now

* update mod.rs

* Hooked up response flow to ConnectedNetwork

* Refactor interface to return result to caller

* Add request and response to message struct

* Clean up some message stuff

* Fix build error

* Hook up request and response fully

* Review myself, impl functions for combine

* Change Receiver interface to spawn task

* try_send instead of send

* Create the task for request handling

* rename request -> response

* fix lint

* clean up request response event handle fn

* fix build

* Comments and make the request signed

* add signature checking

* link gh issue

* Add Event for Validated Quorum Proposal

* Fix consensus task

* fix upgrade test

* start adding the task

* Fix the test...again

* progress

* Finish request task, modify vid disperse event

* create tasks

* Address comments

* fix build

* add delay to config

* fix async std

* fmt

* Make CombinedNetworks delay duration configurable

* Secondary network delay configurable in HotShotConfig

* Rename CombinedConfig to CombinedNetworkConfig

* Network delay in test network generator

`secondary_network_delay` removed from `HotShotConfig`
because it cannot easily be passed to the test network
generator.

* lock

* Temporary pinning to hotshot-types branch

TODO: switch to hotshot-types tag or main branch
before merging

* fixes

* Pin to hotshot-types tag 0.1.2

* Remove files added back by mistake

* fix build

* update hotshot-types

* Remove whitespace

* Fix typo

* fix comment

Subject: [PATCH 0881/1393] Send each recipient one corresponding VID share
 (#2769)

* Send each recipient one corresponding VID share

* `Consensus` and `LeafInfo` have full vid disperse

* Fix deadlock

* Temporarily pin hs-builder-api and fix lint errors

* Make lint happy

* Update hotshot-types to 0.1.6 based version

* `VidDisperseSend` sent as direct message

* hotshot-types and hs-builder-api temporarily pinned to custom branch

* `VidDisperseSend` unpacked and sent as separate messages

* Adapt `Storage` to `VidDisperseShare`

* Fix lint issues

* Move back changes from hotshot-types repo

* Fix docs

* Optimise `DMBehaviour::poll` slightly

* Fix merge issues

* Review fixes

* Fix docs

Subject: [PATCH 0885/1393] [CX_CLEANUP] - Change Consensus Task State to Use
 An Enum Type for Timeout and View Sync Certs (#2810)

* incomplete migration to either type

* split either type at the end of the proposal

* switch to enum type

* change type to use combined view change evidence, move type location, update tests

* disambiguate messaging, fix tests

* do not check stale timeout cert

* add additional proposal checks and improve proposal recv check

* do not store inbound timeout proposal

* fix build for hopefully the last time

Subject: [PATCH 0890/1393] [Catchup] Store High QC When it is Updated (#2807)

* add more action types

* integrate new storage type

* fix build, tie up stragglers, modifying tasks next

* merge latest stable tabs

* merge latest tags and fix method signatures

* working towards adding action to storage

* Store high qc whenever we update it

* fix lint

* adding high_qc to initializer and tests

* typos and if let instead of match

* better comment

* adding state to storage

* add state to initializer

* split high qc and undecided state storage

* fix new clippy lints

Subject: [PATCH 0902/1393] [CX_CLEANUP] - Implement `QuorumProposalTask`
 (#2831)

* add new file

* add qc

* starter

* filling out the trait

* switching branch

* start adding the different payload requirements

* adding context to the events

* fix build, clippy next

* make clippy happy, stub out the rest of the steps

* cosmetic improvements

* Implement task state

* Define a custom re-broadcast type for the quorum proposal (half impl)

* Complete task and event impl with dummy proposal

* fix clippy lints

* fix some logical bugs

* remove log

* update proposal task to combine dependent events

* clarifying comment

* clippy: remove unused import

* remove overuse of validation events

* roll changes down from above branch, remove logs

* remove useless event

* add proposal validated event

* Perform unholy sacriment to get dependencies working

* Perform unholy sacrament to get dependencies working

* shave a layer off

 Testing (#2832)

* add new file

* add qc

* starter

* filling out the trait

* switching branch

* start adding the different payload requirements

* adding context to the events

* fix build, clippy next

* implement a working test for one case, and the failing test

* Complete task and event impl with dummy proposal

* fix clippy lints

* propage delay change throughout

* fix some logical bugs

* remove log

* update proposal task to combine dependent events

* clarifying comment

* clippy: remove unused import

* remove overuse of validation events

* remove sleep in favor of timeout

* fix test runner to broadcast messages

* remove commented code

* remove dead code and events

* roll changes down from above branch, remove logs

* remove useless event

* make timeout duration a global

* remove some noisy logs

* add proposal validated event

* add back the validated event

* Perform unholy sacriment to get dependencies working

* Perform unholy sacrament to get dependencies working

* shave a layer off

Subject: [PATCH 0911/1393] Do not send VID Dispersal through the fallback
 network (#2866)

* Calculate VID shared locally

* Adjust to tokio and adjust tests

* Split DAProsal validation and voting

* Store only successfully signed VID shares

* Do not send VID through the fallback network

* Use the same serialiser

* Fix use statements

+Where ones using `example_gpuvid_leader` could be the leader and should be running on a nvidia GPU, and other validators using `example_fixed_leader` will never be a leader. In practice, these url should be changed to the corresponding ip and port.
+
+
+If you don't have a gpu but want to test out fixed leader, you can run:
+```

+just async_std example_fixed_leader multi-validator-webserver -- 8 http://127.0.0.1:4444
+```
+
+Remember, you have to run leaders first, then other validators, so that leaders will have lower index.

Subject: [PATCH 0931/1393] Cancel Spawned Tasks after Decide in Consensus Task
 (#2929)

* Spawn task for proposing

* Fix tests, return after blank proposal

* fmt and lint

* Keep track of spawned consensus tasks; GC on decide

* Store tasks by view, actually cancel them

Subject: [PATCH 0939/1393] [CX_CLEANUP] - Integrate QuorumProposalTask with
 other tasks (#2927)

* gated, fully clone the behavior

* add propose function, not integrated yet

* finalize the proposal send functionality, test next

* fix simple failing bugs, debugging main test next

* checkpoint

* swap view number

* quick merge

* all success test cases passing

* re-add feature gates

* remove extra log

* tests now passing

* satisfy clippy

* more clippy
fixes

* some cleanup

* fix compilation

* let consensus do what it needs to do

* fix build

* feature gate quorum proposal recv

* fix view number checks

* revert

Subject: [PATCH 0943/1393] Have BlockPayload::get_transactions return an
 iterator (#2946)

This means that the payload is no longer required to explicitly store a list of transactions as a field. We also default-impl a couple other trait functions using this iterator.

Subject: [PATCH 0961/1393] feat: add aztec-srs (#2854)

* add aztec-srs

* use upgraded ark-srs api, and only cached srs upon nix-shell entry

* address comments

* update ci to download srs

* fix linting and quiet wget

* use KZG_TEST and vid_scheme_for_test() instead

* minor update on err msg

Subject: [PATCH 0989/1393] Simplify interaction with builder (#3041)

* Remove block building parameters (`min_transactions`, `max_transactions`,
  `propose_min_round_time`, `propose_max_round_time`) from HotShot, let
  the builder deal with that
* Loop until we successfully get blocks (or time out), but no more than that;
  take a block from the first set that we receive
* Choose block by max fee per byte, not max total fee
* Apply timeout to entire builder interaction, not just `get_available_blocks`

-# Web Server
-
-This crate implements a web server that HotShot can use to increase its throughput.  The web server is designed to be run behind several Nginx instances for high performance.  
-
-The run the web server: `cargo run --features=full-ci --example web_server`.  
-This will start the web server at `0.0.0.0:9000`
-
-## How it works
-Unlike the other networking implementations in `HotShot` that use a *pushing* paradigm over a TCP connection, the web server uses a *pulling* paradigm over HTTP.  In the older centralized server, for example, messages are pushed to nodes from the server.  In contrast, in the web server nodes must poll (pull from) the server periodically to download the latest data.  The direction of dataflow is reversed.  This design allows us to take advantage of Nginx's powerful caching mode, which will improve performance in the large networks `HotShot` is designed for.  Keep in mind that `HotShot` will also be using `Libp2p` in tandem with the web server.  The web server allows high bandwidth through the network under optimistic conditions while `Libp2p` protects against centralization and censorship.  
-
-The web server is built on [Tide Disco](https://github.com/EspressoSystems/tide-disco), an expansion on the popular [Tide](https://docs.rs/tide/0.16.0/tide/index.html) Rust web application framework.  It has several endpoints specified in its `api.toml` file.  These endpoints are what nodes use to either POST or GET messages.  For example, a replica node will poll the web server periodically through the `proposal` endpoint to ask if there is a proposal for its current view.  The server will respond with either an error if there is no proposal for that view yet, or with the proposal.  It works similarly for transactions: Nodes can post transactions to the web server at any time.  They can also download all the transactions they haven't received yet from the web server.

Subject: [PATCH 1009/1393] pass instance_state to `from_transactions` by ref
 (#3096)

This corrects the mistake of passing Arc<dyn InstanceState> to from_transactions. If we pass as reference we can use as an opaque type as we do elsewhere.

-Commands to run da examples: 
-1a)Start web servers by either running 3 servers:
-```
-just async_std example webserver -- <URL_FOR_CDN>
-just async_std example webserver -- <URL_FOR_DA>
-```
-
-2) Start orchestrator:
-```
-just async_std example orchestrator-webserver -- --orchestrator_url <ORCHESTRATOR_URL> --config_file <ORCHESTRATOR_CONFIG_FILE> 
-```
-
-3a) Start validator:
-```
-just async_std example validator-webserver -- <ORCHESTRATOR_URL>
-```
-
-3b) Or start multiple validators:
-```
-just async_std example multi-validator-webserver -- <NUM_VALIDATORS> <ORCHESTRATOR_URL>
-```
-
-I.e. 
-```
-just async_std example webserver -- http://127.0.0.1:9000 
-just async_std example webserver -- http://127.0.0.1:9001 
-just async_std example orchestrator-webserver -- --config_file ./crates/orchestrator/run-config.toml --orchestrator_url http://127.0.0.1:4444 --total_nodes 10 --da_committee_size 5 --transactions_per_round 1 --transaction_size 512 --rounds 10 --fixed_leader_for_gpuvid 0 --webserver_url http://127.0.0.1:9000 --da_webserver_url http://127.0.0.1:9001 
-just async_std example multi-validator-webserver -- 10 http://127.0.0.1:4444
-```
-
-
-OR:
-
-`just async_std example all-webserver -- --config_file ./crates/orchestrator/run-config.toml --orchestrator_url http://localhost:4444`
-
-For other argument setting, checkout `read_orchestrator_init_config` in `crates/examples/infra/mod.rs`.
-
-One example is: `just async_std example all-webserver -- --config_file ./crates/orchestrator/run-config.toml --total_nodes 15`.
-
-Another example is `just async_std example all-webserver -- --config_file ./crates/orchestrator/run-config.toml --total_nodes 20 --da_committee_size 5 --transactions_per_round 10 --transaction_size 512 --rounds 100`, I'll get throughput `0.29M/s` locally for this one.
-
-If using gpu-vid, you have to run:
-```
-just async_std example webserver -- http://127.0.0.1:9000 
-just async_std example webserver -- http://127.0.0.1:9001 
-just async_std example_fixed_leader orchestrator-webserver -- --config_file ./crates/orchestrator/run-config.toml --orchestrator_url http://127.0.0.1:4444 --total_nodes 10 --da_committee_size 5 --fixed_leader_for_gpuvid 1
-just async_std example_gpuvid_leader multi-validator-webserver -- 1 http://127.0.0.1:4444
-sleep 1m
-just async_std example_fixed_leader multi-validator-webserver -- 9 http://127.0.0.1:4444
-```
-
-Where ones using `example_gpuvid_leader` could be the leader and should be running on a nvidia GPU, and other validators using `example_fixed_leader` will never be a leader. In practice, these url should be changed to the corresponding ip and port.
-
-
-If you don't have a gpu but want to test out fixed leader, you can run:
-```
-just async_std example webserver -- http://127.0.0.1:9000 
-just async_std example webserver -- http://127.0.0.1:9001 
-just async_std example_fixed_leader orchestrator-webserver -- --config_file ./crates/orchestrator/run-config.toml --orchestrator_url http://127.0.0.1:4444 --total_nodes 10 --da_committee_size 5 --transactions_per_round 1 --transaction_size 512 --rounds 10 --fixed_leader_for_gpuvid 2 --webserver_url http://127.0.0.1:9000 --da_webserver_url http://127.0.0.1:9001 
-just async_std example_fixed_leader multi-validator-webserver -- 2 http://127.0.0.1:4444
-sleep 1m
-just async_std example_fixed_leader multi-validator-webserver -- 8 http://127.0.0.1:4444
-```
-
-Remember, you have to run leaders first, then other validators, so that leaders will have lower index.

 registered (#3118)

By switching the order of two checks (for manual start and duplicate
keys) we can allow nodes that have already posted their keys, but
restarted, to successfully get a config even after the network has
started.

Subject: [PATCH 1025/1393] Bf/debug (#3136)

* Cycle through recipients until ready to cancel

* Finish `DelayedRequester` tasks when `NetworkRequestState` finishes

All tasks now finish cooperatively

* Fix getter

* Add docs

* reduce locking

* fix

* properly update leaves

* less locking, don't propse after vid recv

* add toolchain back

* fmt

* Bring back task registry

* regular proposal spawning

* Simplify the flags

* logging, lint, fmt

* Remove unnecessary mutability

* revert logging change

* Reduce logging to original level

* comment out dep tests

Subject: [PATCH 1033/1393] Make metrics labels more compatible with Prometheus
 (#3158)

* Add `MetricsFamily` trait to group related metrics that are
  partitioned by values of their labels. This gives us a way to create
  metrics that actually use Prometheus labels, a capability we haven't
  had until now.
* Rename `Label` to `Text` to distinguish it from the Prometheus
  concept of a label
* Change the way `Text` works. Prometheus doesn't support top-level
  key-value pairs with text values, so implementing the old `Label`
  trait for Prometheus, we were forced to hack it by putting the value
  in a comment. A better approach is to have a "text" metric where the
  value of the metric is the name (this can be implemented, e.g., as a
  gauge with a dummy value of 1). Additional key-value pairs can be
  added using families/labels as described above.
* Remove dead code `Metrics` implementations in consensus and networking

The motivation for this is a request from node operators to make the
version metrics populated by the sequencer more parseable. For this,
we only need a family with a single instance, whose label values contain
information like git revision and whatnot. However, this implementation
is more general, and will allow us to fully take advantage of Prometheus
labels if we want to in the future.

Examples of both the simple "version label" usage and a more complex use
of labels can be found in the doc comments.

+/// It forms a Three-Chain, if b'' forms a Two-Chain.
+///
+/// We follow this exact logic to determine if we are able to reach a commit and a decide. A commit
+/// is reached when we have a two chain, and a decide is reached when we have a three chain.
+///
+/// # Example
+/// Suppose we have a decide for view 1, and we then move on to get undecided views 2, 3, and 4. Further,
+/// suppose that our *next* proposal is for view 5, but this leader did not see info for view 4, so the
+/// justify qc of the proposal points to view 3. This is fine, and the undecided chain now becomes
+/// 2-3-5.
+///
+/// Assuming we continue with honest leaders, we then eventually could get a chain like: 2-3-5-6-7-8. This
+/// will prompt a decide event to occur (this code), where the `proposal` is for view 8. Now, since the
+/// lowest value in the 3-chain here would be 5 (excluding 8 since we only walk the parents), we begin at
+/// the first link in the chain, and walk back through all undecided views, making our new anchor view 5,
+/// and out new locked view will be 6.
+///
+/// Upon receipt then of a proposal for view 9, assuming it is valid, this entire process will repeat, and
+/// the anchor view will be set to view 6, with the locked view as view 7.

+/// Macro to run the test suite with `TaskState` scripts at once with the ability to.
+/// Randomize the input values using a consistent seed value.
+///
+/// **Note** When using `random!` you should use `all_predicates` in the output to ensure
+/// that the test does not fail due to events happening out of order!
+///
+/// Usage:
+///
+///   `run_test[inputs, script1, script2, ...]`
+///
+/// The generated test will:
+///   - take the first entry of `inputs`, which should be a `Vec<HotShotEvent<TYPES>>`,
+///   - if the input is random, it'll generate a `seed` and shuffle the inputs.
+///   - if the input is serial, it will execute in order.
+///   - print the seed being used.
+///   - feed this to each task in order, validating any output received before moving on to the next one,
+///   - repeat the previous steps, with the aggregated outputs received from all tasks used as the new input set,
+///   - repeat until no more output has been generated by any task, and finally
+///   - proceed to the next entry of inputs.
+///   - print the seed being used (again) to make finding it a bit easier.

+///
+/// > When a node b* carries a QC that refers to a direct parent, i.e., b*.justify.node = b*.parent,
+/// we say that it forms a One-Chain. Denote by b'' = b*.justify.node. Node b* forms a Two-Chain,
+/// if in addition to forming a One-Chain, b''.justify.node = b''.parent.
+/// It forms a Three-Chain, if b'' forms a Two-Chain.
+///
+/// We follow this exact logic to determine if we are able to reach a commit and a decide. A commit
+/// is reached when we have a two chain, and a decide is reached when we have a three chain.
+///
+/// # Example
+/// Suppose we have a decide for view 1, and we then move on to get undecided views 2, 3, and 4. Further,
+/// suppose that our *next* proposal is for view 5, but this leader did not see info for view 4, so the
+/// justify qc of the proposal points to view 3. This is fine, and the undecided chain now becomes
+/// 2-3-5.
+///
+/// Assuming we continue with honest leaders, we then eventually could get a chain like: 2-3-5-6-7-8. This
+/// will prompt a decide event to occur (this code), where the `proposal` is for view 8. Now, since the
+/// lowest value in the 3-chain here would be 5 (excluding 8 since we only walk the parents), we begin at
+/// the first link in the chain, and walk back through all undecided views, making our new anchor view 5,
+/// and out new locked view will be 6.
+///
+/// Upon receipt then of a proposal for view 9, assuming it is valid, this entire process will repeat, and

-/// Ascends the leaf chain by traversing through the parent commitments of the proposal. We begin
-/// by obtaining the parent view, and if we are in a chain (i.e. the next view from the parent is
-/// one view newer), then we begin attempting to form the chain. This is a direct impl from
-/// [HotStuff](https://arxiv.org/pdf/1803.05069) section 5:
-///
-/// > When a node b* carries a QC that refers to a direct parent, i.e., b*.justify.node = b*.parent,
-/// we say that it forms a One-Chain. Denote by b'' = b*.justify.node. Node b* forms a Two-Chain,
-/// if in addition to forming a One-Chain, b''.justify.node = b''.parent.
-/// It forms a Three-Chain, if b'' forms a Two-Chain.
-///
-/// We follow this exact logic to determine if we are able to reach a commit and a decide. A commit
-/// is reached when we have a two chain, and a decide is reached when we have a three chain.
-///
-/// # Example
-/// Suppose we have a decide for view 1, and we then move on to get undecided views 2, 3, and 4. Further,
-/// suppose that our *next* proposal is for view 5, but this leader did not see info for view 4, so the
-/// justify qc of the proposal points to view 3. This is fine, and the undecided chain now becomes
-/// 2-3-5.
-///
-/// Assuming we continue with honest leaders, we then eventually could get a chain like: 2-3-5-6-7-8. This
-/// will prompt a decide event to occur (this code), where the `proposal` is for view 8. Now, since the
-/// lowest value in the 3-chain here would be 5 (excluding 8 since we only walk the parents), we begin at
-/// the first link in the chain, and walk back through all undecided views, making our new anchor view 5,
-/// and out new locked view will be 6.
-///
-/// Upon receipt then of a proposal for view 9, assuming it is valid, this entire process will repeat, and
-/// the anchor view will be set to view 6, with the locked view as view 7.

+Steps
+---------------
+
+KeyDB is the ephemeral database, it's like Redis but with extra features. The only thing we run it with is with `--requirepass` to set a password.
+
+**Marshals:**
+The marshal is the entry point of the push CDN, all users connect there first. It tells users which broker to connect to.
+
+- `-d` is the "discovery endpoint", which in this case is the URL of KeyDB.
+- `-b` is the bind port. This is what you would set in run_config.toml for cdn_broker_marshal_endpoint
+- `-m` is metrics stuff. You shouldn't have to use that
+
+
+**Brokers:**
+In a run with multiple machines, we want two brokers. With one machine, it's probably fine to do one broker. These are what route the messages. Here are the relevant command line arguments:
+
+- `-d` is the "discovery endpoint", which in this case is the URL of KeyDB.
+- `--public-bind-endpoint`: the endpoint which we bind to locally for users to connect to (e.g. 0.0.0.0:1740)
+- `--public-advertise-endpoint`: the endpoint which we advertise to users (e.g. my.public.ip:1740)
+- `--private-bind-endpoint`: the endpoint which we bind to locally for brokers to connect to (e.g. 0.0.0.0:1741)
+- `--private-advertise-endpoint`: the endpoint which we advertise to brokers (e.g. my.public.ip:1741)
+- `-m` is metrics stuff. You shouldn't have to use that
+For brokers, there is a magic value called `local_ip`. This resolves to the local IP address, which skips the need for talking to the AWS metadata server. For in-AWS uses, the following configuration is probably fine:
+`cdn-broker --public-bind-endpoint 0.0.0.0:1740 --public-advertise-endpoint local_ip:1740 --private-bind-endpoint 0.0.0.0:1741 --private-advertise-endpoint local_ip:1741`. You won't need to put this port or values anywhere, as the marshal does everything for you.
+
+Examples:
+---------------
+
+**Run Locally** 
+
+`just async_std example all-push-cdn -- --config_file ./crates/orchestrator/run-config.toml`
+
+OR
+
+```
+docker run --rm -p 0.0.0.0:6379:6379 eqalpha/keydb
+just async_std example cdn-marshal -- -d redis://localhost:6379 -b 9000
+just async_std example cdn-broker -- -d redis://localhost:6379 --public-bind-endpoint 0.0.0.0:1740 --public-advertise-endpoint local_ip:1740 --private-bind-endpoint 0.0.0.0:1741 --private-advertise-endpoint local_ip:1741
+just async_std example orchestrator -- --config_file ./crates/orchestrator/run-config.toml --orchestrator_url http://0.0.0.0:4444
+just async_std example multi-validator-push-cdn -- 10 http://127.0.0.1:4444
+```
+
+**Run with GPU-VID** 
+```
+docker run --rm -p 0.0.0.0:6379:6379 eqalpha/keydb
+just async_std example cdn-marshal -- -d redis://localhost:6379 -b 9000
+just async_std example cdn-broker -- -d redis://localhost:6379 --public-bind-endpoint 0.0.0.0:1740 --public-advertise-endpoint local_ip:1740 --private-bind-endpoint 0.0.0.0:1741 --private-advertise-endpoint local_ip:1741
+just async_std example_fixed_leader orchestrator -- --config_file ./crates/orchestrator/run-config.toml --orchestrator_url http://0.0.0.0:4444 --fixed_leader_for_gpuvid 1
+just async_std example_gpuvid_leader multi-validator-push-cdn -- 1 http://127.0.0.1:4444
+sleep 1m
+just async_std example_fixed_leader multi-validator-push-cdn -- 9 http://127.0.0.1:4444
+```
+
+Where ones using `example_gpuvid_leader` could be the leader and should be running on a nvidia GPU, and other validators using `example_fixed_leader` will never be a leader. In practice, these url should be changed to the corresponding ip and port.
+
+
+If you don't have a gpu but want to test out fixed leader, you can run:
+```
+docker run --rm -p 0.0.0.0:6379:6379 eqalpha/keydb
+just async_std example cdn-marshal -- -d redis://localhost:6379 -b 9000
+just async_std example cdn-broker -- -d redis://localhost:6379 --public-bind-endpoint 0.0.0.0:1740 --public-advertise-endpoint local_ip:1740 --private-bind-endpoint 0.0.0.0:1741 --private-advertise-endpoint local_ip:1741
+just async_std example_fixed_leader orchestrator -- --config_file ./crates/orchestrator/run-config.toml --orchestrator_url http://0.0.0.0:4444 --fixed_leader_for_gpuvid 1
+just async_std example_fixed_leader multi-validator-push-cdn -- 1 http://127.0.0.1:4444
+sleep 1m
+just async_std example_fixed_leader multi-validator-push-cdn -- 9 http://127.0.0.1:4444
+```
+
+Remember, you have to run leaders first, then other validators, so that leaders will have lower index.

-/// Ascends the leaf chain by traversing through the parent commitments of the proposal. We begin
-/// by obtaining the parent view, and if we are in a chain (i.e. the next view from the parent is
-/// one view newer), then we begin attempting to form the chain. This is a direct impl from
-/// [HotStuff](https://arxiv.org/pdf/1803.05069) section 5:
-///
-/// > When a node b* carries a QC that refers to a direct parent, i.e., b*.justify.node = b*.parent,
-/// we say that it forms a One-Chain. Denote by b'' = b*.justify.node. Node b* forms a Two-Chain,
-/// if in addition to forming a One-Chain, b''.justify.node = b''.parent.
-/// It forms a Three-Chain, if b'' forms a Two-Chain.
-///
-/// We follow this exact logic to determine if we are able to reach a commit and a decide. A commit
-/// is reached when we have a two chain, and a decide is reached when we have a three chain.
-///
-/// # Example
-/// Suppose we have a decide for view 1, and we then move on to get undecided views 2, 3, and 4. Further,
-/// suppose that our *next* proposal is for view 5, but this leader did not see info for view 4, so the
-/// justify qc of the proposal points to view 3. This is fine, and the undecided chain now becomes
-/// 2-3-5.
-///
-/// Assuming we continue with honest leaders, we then eventually could get a chain like: 2-3-5-6-7-8. This
-/// will prompt a decide event to occur (this code), where the `proposal` is for view 8. Now, since the
-/// lowest value in the 3-chain here would be 5 (excluding 8 since we only walk the parents), we begin at
-/// the first link in the chain, and walk back through all undecided views, making our new anchor view 5,
-/// and out new locked view will be 6.
-///
-/// Upon receipt then of a proposal for view 9, assuming it is valid, this entire process will repeat, and
-/// the anchor view will be set to view 6, with the locked view as view 7.

+/// [HotStuff](https://arxiv.org/pdf/1803.05069) section 5:
+///
+/// > When a node b* carries a QC that refers to a direct parent, i.e., b*.justify.node = b*.parent,
+/// we say that it forms a One-Chain. Denote by b'' = b*.justify.node. Node b* forms a Two-Chain,
+/// if in addition to forming a One-Chain, b''.justify.node = b''.parent.
+/// It forms a Three-Chain, if b'' forms a Two-Chain.
+///
+/// We follow this exact logic to determine if we are able to reach a commit and a decide. A commit
+/// is reached when we have a two chain, and a decide is reached when we have a three chain.
+///
+/// # Example
+/// Suppose we have a decide for view 1, and we then move on to get undecided views 2, 3, and 4. Further,
+/// suppose that our *next* proposal is for view 5, but this leader did not see info for view 4, so the
+/// justify qc of the proposal points to view 3. This is fine, and the undecided chain now becomes
+/// 2-3-5.
+///
+/// Assuming we continue with honest leaders, we then eventually could get a chain like: 2-3-5-6-7-8. This
+/// will prompt a decide event to occur (this code), where the `proposal` is for view 8. Now, since the
+/// lowest value in the 3-chain here would be 5 (excluding 8 since we only walk the parents), we begin at
+/// the first link in the chain, and walk back through all undecided views, making our new anchor view 5,
+/// and out new locked view will be 6.
+///
+/// Upon receipt then of a proposal for view 9, assuming it is valid, this entire process will repeat, and
+/// the anchor view will be set to view 6, with the locked view as view 7.

+/// [HotStuff](https://arxiv.org/pdf/1803.05069) section 5:
+///
+/// > When a node b* carries a QC that refers to a direct parent, i.e., b*.justify.node = b*.parent,
+/// we say that it forms a One-Chain. Denote by b'' = b*.justify.node. Node b* forms a Two-Chain,
+/// if in addition to forming a One-Chain, b''.justify.node = b''.parent.
+/// It forms a Three-Chain, if b'' forms a Two-Chain.
+///
+/// We follow this exact logic to determine if we are able to reach a commit and a decide. A commit
+/// is reached when we have a two chain, and a decide is reached when we have a three chain.
+///
+/// # Example
+/// Suppose we have a decide for view 1, and we then move on to get undecided views 2, 3, and 4. Further,
+/// suppose that our *next* proposal is for view 5, but this leader did not see info for view 4, so the
+/// justify qc of the proposal points to view 3. This is fine, and the undecided chain now becomes
+/// 2-3-5.
+///
+/// Assuming we continue with honest leaders, we then eventually could get a chain like: 2-3-5-6-7-8. This
+/// will prompt a decide event to occur (this code), where the `proposal` is for view 8. Now, since the
+/// lowest value in the 3-chain here would be 5 (excluding 8 since we only walk the parents), we begin at
+/// the first link in the chain, and walk back through all undecided views, making our new anchor view 5,
+/// and out new locked view will be 6.
+///
+/// Upon receipt then of a proposal for view 9, assuming it is valid, this entire process will repeat, and
+/// the anchor view will be set to view 6, with the locked view as view 7.

-/// Ascends the leaf chain by traversing through the parent commitments of the proposal. We begin
-/// by obtaining the parent view, and if we are in a chain (i.e. the next view from the parent is
-/// one view newer), then we begin attempting to form the chain. This is a direct impl from
-/// [HotStuff](https://arxiv.org/pdf/1803.05069) section 5:
-///
-/// > When a node b* carries a QC that refers to a direct parent, i.e., b*.justify.node = b*.parent,
-/// we say that it forms a One-Chain. Denote by b'' = b*.justify.node. Node b* forms a Two-Chain,
-/// if in addition to forming a One-Chain, b''.justify.node = b''.parent.
-/// It forms a Three-Chain, if b'' forms a Two-Chain.
-///
-/// We follow this exact logic to determine if we are able to reach a commit and a decide. A commit
-/// is reached when we have a two chain, and a decide is reached when we have a three chain.
-///
-/// # Example
-/// Suppose we have a decide for view 1, and we then move on to get undecided views 2, 3, and 4. Further,
-/// suppose that our *next* proposal is for view 5, but this leader did not see info for view 4, so the
-/// justify qc of the proposal points to view 3. This is fine, and the undecided chain now becomes
-/// 2-3-5.
-///
-/// Assuming we continue with honest leaders, we then eventually could get a chain like: 2-3-5-6-7-8. This
-/// will prompt a decide event to occur (this code), where the `proposal` is for view 8. Now, since the
-/// lowest value in the 3-chain here would be 5 (excluding 8 since we only walk the parents), we begin at
-/// the first link in the chain, and walk back through all undecided views, making our new anchor view 5,
-/// and out new locked view will be 6.
-///
-/// Upon receipt then of a proposal for view 9, assuming it is valid, this entire process will repeat, and
-/// the anchor view will be set to view 6, with the locked view as view 7.

-HotShot uses an event-based architecture.  This architecture is made of 4 main tasks: Network Task, View Sync Task, Consensus Task, and DA Task.  The Network Task handles all incoming and outgoing messages.  It forwards incoming messages to the correct task and listens for outgoing messages from the other tasks.  The View Sync Task coordinates the view sync protocol.  It listens for timeout events from the Consensus Task.  Once a certain threshold of timeouts seen has been reached, the View Sync Task starts the View Sync protocol to bring the network back into agreement on which view it should be in. The Consensus Task handles the core HotShot consensus logic.  It manages replicas that listen for quourm propsoals and vote on them, leaders who send quorum proposals, and next leaders who listen for quorum votes and form QCs.  The DA task handles the data availability protocol of HotShot.  It listens for DA proposals, sends DA proposals, and forms a Data Availability Certificate (DAC)

 (#3516)

* add a test case where we have dishonest leader

* add functionality to fail out if we fail unexpected view

* cleanup, use last validated proposal

* add a view lookback when getting the QC

* address comments

* ensure all the views we expect to fail actually fail

* remove debug log

* fix test

Subject: [PATCH 1205/1393] [CATCHUP] Init Consensus with 2 views to prevent
 Double Vote/Propose (#3648)

* Add second view param to init, spin nodes in tests up from view 0

* add last actioned views to consensus

* check view before doing action

* fmt and lint

* log error when trying to double propose/vote

* fix for DA votes

* still update the da vote view

* restart with actioned view from storage

* lint

* Allow access to consensus from byz tests, reset actions in byz behavior

* lint

Subject: [PATCH 1226/1393] Fix Hanging CI (#3697)

* shutdown completion task last

* fix shutdown order

* fmt

* log everything at info when test fails

* clear failed, logging

* fix build

* different log level

* no capture again

* typo

* move logging + do startups in parallel

* fmt

* change initial timeout

* remove nocapture

* nocapture again

* fix

* only log nodes started when there are nodes starting

* log exit

* log when timeout starts

* log id and view

* only shutdown from 1 place

* fix build, remove handles from completetion task

* leave one up in cdn test

* more logs, less threads, maybe fix?

* actual fix

* lint fmt

* allow more than 1 thread, tweaks

* remove nocapture

* move byzantine tests to ci-3

* rebalance tests more

* one more test to 4

* only spawn first timeout when starting consensus

* cleanup

* fix justfile lint tokio

* fix justfil

* sleep longer, nocapture to debug

* info

* fix another hot loop maybe

* don't spawn r/r tasks for cdn that do nothing

* lint no sleep

* lower log level in libp2p

* lower builder test threshold

* remove nocapture for the last time, hopefully

* remove cleanup_previous_timeouts_on_view

Subject: [PATCH 1264/1393] Replace VidScheme assoc type aliases with newtype
 wrappers (#3794)

* crates/types/src/vid.rs convert VidCommitment from type alias to newtype wrapper; this newtype is not AsRef or Copy; all other changes in this commit convert as_ref() to bincode::serialize and copy to clone()

* convert VidCommon from type alias to newtype wrapper

* convert VidShare from type alias to newtype wrapper

* convert VidPrecomputeData from type alias to newtype wrapper

* clippy pacification

* revert bincode::serialize -> as_ref for VID commitment serialization

* doc tweaks

* VidCommitment impl AsRef<[u8; 32]> instead of AsRef<[u8]>

-//! Purpose: the specific choice of VID scheme is an implementation detail. We
-//! want all communication with the VID scheme to occur only via the API exposed
-//! in the [`VidScheme`] trait, but limitations of Rust make it difficult to

Subject: [PATCH 1280/1393] Lr/epoch end (#3806)

* Initial commit

* Propose the same block at the end of the epoch

* No VID and DAC required for the additional last block proposals

* Guard against division by 0

* Traverse the leaves to check an eQC

* Remove unneeded async in function definition

* Remove trace

* Make sure proposal is for the same block if justify QC references the last block

* Gate epoch proposal logic

* Gate epochs voting logic

* Create helper method to check if QC is part of 3-chain

* Fixes after review

* Get rid of nasty nested if-elses

* Fix fmt

* Update VID that we reuse at the end of the epoch

* Fix fmt

* Do not create VID and DAC dependencies when voting for the last block

* Simplify how we get a header

Subject: [PATCH 1284/1393] View Change Fix (#3795)

* move storage to end of proposal processing

* don't fetch proposal so until we really need it

* whoops wrong fetch

* fix test

* spawn fetch proposal

* revert test

* Kill old network tasks

* check view everywhere

* prepare to spawn validation in task

* fmt and lint

* fixes after merge

* fix off by ones

* fmt

* remove dead da code, off by one fix

* remove some checks

* move view change event to same spot

* actually spawn a new timeout task?

* view numbers are hard

* log emit view change earlier

* fix test with failures

* give network tasks one more view

* cancel timeout task at the end, let vote live longer

* Try not cancelling newtork tasks

* one extra view for Request tasks

* view - 1

* fire and forget

* less cancel

* Sapwn vid task off by 1 fix

* ignore view delay test b/c it doesn't make sense

* don't update view until proposal validated

* don't double spawn timeout

* proper view numbers

* logging

* some fixes

* test fixes

* fix

* view change is the view of current proposal

* revert logging

* fix tests

* fix txn task view num

* pr comments

* Send view change on epoch voting

 In these tests, there are three types of nodes. `Regular` nodes that limit the number of incoming connections, `Bootstrap` nodes that allow all connections, and `Conductor` nodes that all nodes (bootstrap and regular) connect to and periodically ping with their state. This "conductor" node instructs nodes in the swarm to increment their state either via broadcast or direct messages in the same fashion as the single machine tests.
 
-In the direct message case, the conductor will increment the state of a randomly chosen node, `i`. Then the conductor will direct message all other nodes to request node `i`'s counter and increment their counter to the value in `i`'s node. In the broadcast case, the conductor will increment the state of a randomly chose node, `i`, and tell `i` to broadcast this incremented state.

In the broadcast case, the conductor will increment the state of a randomly chosen node, `i`, and tell `i` to broadcast this incremented state.
 
 In both cases, the test terminates as successful when the conductor receives the incremented state from all other nodes. Then, the conductor sends a special "kill" message to all known nodes and waits for them to disconnect.
 
-Metadata about the toplogy is currently read from an `identity_mapping.json` file that manually labels the type of node (bootstrap, regular, conductor). The conductor uses this to figure out information about all nodes in the network. The regular nodes use this to learn about their ip address and the addresses necessary to bootstrap onto the network. The boostrap nodes only use this to learn about their ip addresses.

-# USAGE
-
-Networking library intended for use with HotShot. Builds upon abstractions from libp2p-rs.
-
-## CLI Demo
-
-To get very verbose logging:
-
-```bash
-RUST_LOG_OUTPUT=OUTFILE RUST_LOG="trace" cargo run --features=async-std-executor --release
-```
-
-The idea here is to spin up several nodes in a p2p network. These nodes can share messages with each other.
-
-```
-nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- -p 1111"
-nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/1111/quic-v1 -p 2222"
-nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/2222/quic-v1 -p 3333"
-nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/3333/quic-v1 -p 4444"
-nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/4444/quic-v1 -p 5555"
-nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/5555/quic-v1 -p 6666"
-nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/6666/quic-v1 -p 7777"
-nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/7777/quic-v1 -p 8888"
-nix develop -c "RUST_LOG_OUTPUT=OUTFILE_0 RUST_LOG=error cargo run --features=async-std-executor --release --example clichat -- /ip4/127.0.0.1/udp/8888/quic-v1 -p 9999"
-```
-
-At this point the idea is that each node will continue to attempt to connect to nodes
-until it hits at least 5 peers.
-
-Use `Tab` to switch between messages and prompt. Press `Enter` to broadcast a message to all connected nodes.
-Press `Right Arrow` to direct-send a message to a randomly selected peer.
-Press `q` to quit the program from the messages view.
-
-## Counter Single Machine Tests
-
-Each node has its own counter. The idea behind these tests is to support "broadcast" messages and "direct" messages to increment each nodes counter.
-
-`cargo test --features=async-std-executor --release stress`
-
-spawns off five integration tests.
-
-- Two that uses gossipsub to broadcast a counter increment from one node to all other nodes
-- Two where one node increments its counter, then direct messages all nodes to increment their counters
-- One that intersperses both broadcast and increments.
-- One that intersperses both broadcast and increments.
-- Two that publishes entries to the DHT and checks that other nodes can access these entries.
-
-This can fail on MacOS (and linux) due to "too many open files." The fix is:
-
-```bash
-ulimit -n 4096
-```
-
-## Counter Multi-machine tests
-
-In these tests, there are three types of nodes. `Regular` nodes that limit the number of incoming connections, `Bootstrap` nodes that allow all connections, and `Conductor` nodes that all nodes (bootstrap and regular) connect to and periodically ping with their state. This "conductor" node instructs nodes in the swarm to increment their state either via broadcast or direct messages in the same fashion as the single machine tests.
-
-In the direct message case, the conductor will increment the state of a randomly chosen node, `i`. Then the conductor will direct message all other nodes to request node `i`'s counter and increment their counter to the value in `i`'s node. In the broadcast case, the conductor will increment the state of a randomly chosen node, `i`, and tell `i` to broadcast this incremented state.
-
-In both cases, the test terminates as successful when the conductor receives the incremented state from all other nodes. Then, the conductor sends a special "kill" message to all known nodes and waits for them to disconnect.
-
-Metadata about the topology is currently read from an `identity_mapping.json` file that manually labels the type of node (bootstrap, regular, conductor). The conductor uses this to figure out information about all nodes in the network. The regular nodes use this to learn about their ip address and the addresses necessary to bootstrap onto the network. The bootstrap nodes only use this to learn about their ip addresses.
-
-### Running counter multi-machine tests
-
-A sample invocation locally:
-
-```bash
-# run each line in a separate terminal
-nix develop -c cargo run --features webui,async-std-executor  --release --example counter -- --bound_addr 127.0.0.1:9000 --node_type Bootstrap --num_nodes 5 --bootstrap 127.0.0.1:9000 --webui 127.0.0.1:8000
-nix develop -c cargo run --features webui,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9001 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --webui 127.0.0.1:8001
-nix develop -c cargo run --features webui,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9002 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --webui 127.0.0.1:8002
-nix develop -c cargo run --features webui,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9003 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --webui 127.0.0.1:8003
-nix develop -c cargo run --features webui,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9004 --node_type Conductor --num_nodes 5 --bootstrap 127.0.0.1:9000 --webui 127.0.0.1:8004
-```
-
-### Network Emulation
-One may introduce simulated network latency via the network emulation queueing discipline. This is implemented in two ways: on what is assumed to be a AWS EC2 instance, and in a docker container. Example usage on AWS EC2 instance:
-
-```bash
-# run each line in a separate AWS instance
-nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9000 --node_type Bootstrap --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Metal
-nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9001 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Metal
-nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9002 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Metal
-nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9003 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Metal
-nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9004 --node_type Conductor --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Metal
-```
-
-And on docker:
-
-```bash
-# run each line in a separate Docker container instance
-nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9000 --node_type Bootstrap --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Docker
-nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9001 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Docker
-nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9002 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Docker
-nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9003 --node_type Regular --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Docker
-nix develop -c cargo run --features lossy_network,async-std-executor --release --example counter -- --bound_addr 127.0.0.1:9004 --node_type Conductor --num_nodes 5 --bootstrap 127.0.0.1:9000 --env Docker
-```
-
-On an AWS instance, a separate network namespace is created and connected to `ens5` via a network bridge, and a netem qdisc is introduced to the veth interface in the namespace. Within a docker container, a netem qdisc is added on interface `eth0`.
-
-### Network Emulation Dockerfile
-
-Usage:
-
-```
-docker build . -t libp2p-networking
-# expose ports
-docker run -P 8000:8000 -P 9000:9000 libp2p-networking
-```

Subject: [PATCH 1299/1393] Lr/increment epoch (#3828)

* Initial commit

* Propose the same block at the end of the epoch

* No VID and DAC required for the additional last block proposals

* Guard against division by 0

* Traverse the leaves to check an eQC

* Remove unneeded async in function definition

* Remove trace

* Make sure proposal is for the same block if justify QC references the last block

* Initial commit

* Gate epoch proposal logic

* Gate epochs voting logic

* Create helper method to check if QC is part of 3-chain

* Update epoch on `ViewChange` event

* Adjust tests

* Update view and epoch when QC is formed

* Fixes after review

* Get rid of nasty nested if-elses

* Fix fmt

* Update VID that we reuse at the end of the epoch

* Fix fmt

* Do not create VID and DAC dependencies when voting for the last block

* Simplify how we get a header

* Correctly update epoch when voting and forming QC

* Send ViewChange event when voting after shared state's been updated

* Adjust tests

* Remove an obsolete DA ViewChange code

* Fetch proposal if missing when changing view after forming QC

* Fix deadlock

* Update epoch only when receiving or forming an eQC

* update logging (#3844)

* [Tech debt] Remove `async-std` (#3845)

* tests and CI

* remove `async-std`

* `fmt`

* fix doc build

Subject: [PATCH 1300/1393] Lr/eqc voting (#3851)

* Initial commit

* Propose the same block at the end of the epoch

* No VID and DAC required for the additional last block proposals

* Guard against division by 0

* Traverse the leaves to check an eQC

* Remove unneeded async in function definition

* Remove trace

* Make sure proposal is for the same block if justify QC references the last block

* Initial commit

* Gate epoch proposal logic

* Gate epochs voting logic

* Create helper method to check if QC is part of 3-chain

* Update epoch on `ViewChange` event

* Adjust tests

* Update view and epoch when QC is formed

* Fixes after review

* Get rid of nasty nested if-elses

* Fix fmt

* Update VID that we reuse at the end of the epoch

* Fix fmt

* Do not create VID and DAC dependencies when voting for the last block

* Simplify how we get a header

* NetworkEventTaskState uses OuterConsensus

* Refactor some of the eQC related methods in `Consensus`

* Add back a debugging trace

* Last eQC vote is broadcast

* Do not check if we are the leader when receiving last votes for eQC

* Add more traces

* Correctly update epoch when voting and forming QC

* Send ViewChange event when voting after shared state's been updated

* Adjust tests

* Remove an obsolete DA ViewChange code

* Fetch proposal if missing when changing view after forming QC

* Fix deadlock

* Update epoch only when receiving or forming an eQC

* update logging (#3844)

* [Tech debt] Remove `async-std` (#3845)

* tests and CI

* remove `async-std`

* `fmt`

* fix doc build

Subject: [PATCH 1305/1393] Hotstuff 2 (#3877)

* removing some unused stuff and adding HighQC message + event

* Update high qc events, add helper to send

* Send high Qc on view change

* wait for highest qc in the proposal task

* fn stub

* working on fn

* new decide rule and locked qc rule for hs2

* Merge main

* add failures test

* actually use new decide rule

* add test verifying the new decide rule is one shorter

* reduce epoch chain len by 1

* fix waiting and validate QC

* use proper timeout

* more accurate high qc waiting logic

* gate by versios before waiting for QC

* Fix GC for epochs

* fix version gating

Subject: [PATCH 1315/1393] CI: add typos job (#3916)

* CI: add typos job

- Add typos to flake .nix.
- Add typos config file: ignore files with false hits.

There are mostly fixes to comments but a few small changes to rust code
as well. Theres should be no functional changes or changes to public
interfaces.

Subject: [PATCH 1317/1393] Flatten memberships into a single type (#3867)

Delete Memberships and replace functionality. Add some methods to
`Membership` trait to deal w/ collapsing into one type both kinds of
memberships (stake and DA).

  * avoid passing membership into `is_valid_cert (see #3918)
  * for DA, avoid proxying threshold through `Threshold` trait
  * remove `Topic` param from `Membership::new
  * Split cert impls by marker (#3891)
  * add membership methods to Cert trait
  * remove non-existent test from justfile

Subject: [PATCH 1321/1393] Add randomized Membership impls for testing (#3863)

* replace calls to Memberships

Delete Memberships and replace functionality. Add some methods to
`Membership` trait to deal w/ collapsing into one type both kinds of
memberships (stake and DA).

  * avoid passing membership into `is_valid_cert
  * for DA, avoid proxying threshold through `Threshold` trait
  * remove `Topic` param from `Membership::new
  * Split cert impls by marker (#3891)
  * add membership methods to Cert trait
  * remove non-existent tests from justfile

* cleanup

* conflict resolution

* revert some unnecessary name changes

We can keep the old name where we only have one membership type to
keep the diff smaller.

* Leaders are Leaders

Always use quorum for leader selection

* Add randomized committees for testing

* add randomized overlap committee generator

* Add epoch to threshold functions to allow dynamically sized committees

* rework randomized_committee_members to work with flattened Membership

* fix lingering da_leader things

* 3933 DrbComputations helper for quorum_vote

* 3933 modify logic of drb computation to start at epoch transition

* 3933 check for if we should store the seed based on when we're expecting to be in the committee

* 3933 always start the task for drb

* 3933 fix clippy lints

* 3933 avoid unwrapping leaf_views.last()

* 3933 additional fixes

* 3933 correct nits, use proposal block number to calculate epoch number

* 3933 break drb_calculation_start and drb_calculation_seed into separate functions

* 3933 fix comment

Subject: [PATCH 1336/1393] Lr/epoch tests (#3952)

* Initial commit

* WIP: adding epoch to proposal and vote data, not compiling yet

* Make it compile

* Adjust tests

* Add a test type for two stake tables for even and odd epochs

* Debugging

* Fix extended voting

* Try "in epoch transition" approach

* Continue debugging

* Use correct epoch with Membership

* Adjust tests and lints

* Adapt to variable stake table after merge

* Fix accidentally pulled bug in eQC rule

* Commit includes epoch for vote and proposal data types

* Prune dependencies (#3787)

* add new message types and gate outgoing messages

* Use the proper message for the proposal response

* Modify commit for `Leaf2` and `QuorumData2`

* Adjust tests

* Clean up debug traces

* Initial commit for double quorum

* Add TODO

* Next epoch nodes vote during epoch transition

* Form the second QC at the end of an epoch

* Allow early payload save but check that's it's the same

* Attach next epoch justify qc to proposals

* Validate the next epoch justify qc

* Test with more network types

* Fix fmt in tests

* Use real threshold in the tests based on an epoch

* Membership thresholds depend on an epoch

* Make sure epoch transition proposals include the next epoch QC

* Use epoch from vote and add more tests

* Adjust marketplace ver number

* Epochs without Marketplace and adjust tests

* Add epoch to test_success

* Add debug traces

* try

* Adjust view change logic in transactions task

* Cleanup debug traces

* Don't chage view when voting for eQC

* Add a lot of traces to find a deadlock

* Keep the task for view one less than the current. We might still be transmitting

* Clean debug traces

* An epoch should not increment without view being incremented as well

* Use saturating_sub consistently

* Fix compiler error

* fix merge

* Add a new test

* Fixes after merge

* Fix vid share handling

* Submit transactions to the correct epoch

* Address review comments

* Fix compiler error

* Adjust test

* test_with_failures_2_with_epochs test uses only TestTwoStakeTablesTypes

* Modify test_epoch_end to use uneven number of nodes, it now fails

* VID share required target epoch as well

* VID share needs old epoch payload commitment

* Use odd number of nodes in tests

* Remove debug trace

Subject: [PATCH 1360/1393] Lr/epochs more tests (#4005)

* Add more epoch tests

* Do not fail if the new locked view is the same as the stored locked view

* Add catchup test for epochs and retrieve stored VIDs after restart

* Make sure that the decided view is greater than the old one when GCing

* Fix test_with_failures_half_f

* Revert "Do not fail if the new locked view is the same as the stored locked view"

This reverts commit f4f37ef25ef8490629acbbff10a8da5baa16550f.

* Revert "Make sure that the decided view is greater than the old one when GCing"

This reverts commit 91af3abbc649b48f8beb44d26c58e09e702ca9e7.

* Make sure the new view is greater than the old one before GCing

* Return None instead of exiting with Error if no VID

* Move epoch tests to a separate file

Subject: [PATCH 1374/1393] Generalized request/response protocol (#4071)

* tcp -> quic patch

* add r/r protocol

* `Serializable`

* split out everything

* refactor messages, test serialization

* move request validation and add tests for it

* add handlers

* finish most of the responding logic

* `blake3`, `bounded_vec_deque`

* testing-only `PartialEq`

* finish sending logic

* move to separate crate, `clippy`

* `Vec<u8>` -> `Arc<Vec<u8>>`, begin integration tests

* integration tests

* `1_10s` -> `1_20s`

* reduce test time

* revert unnecessary `transport` change

* un-type-alias export

* remove dep from utils

* `fmt`

* add `VecDeque` test

* add some helpful comments

* even moar comments

* general improvements

* nice refactor

* comments, readability

* reorg

* add test for request joining

* add a helper function to request indefinitely

* `fmt`

* merge main in

* run `hakari`

* use `tokio`'s `AbortOnDropHandle` instead

* cargo hakari

* make everything async

* move request validation logic up

* hakari

Subject: [PATCH 1379/1393] Epoch-enabled catchup tests (#4070)

* Add catchup tests, store last epoch

* Adjust overall safety task to variable stake tables

* Use node's current epoch in tests

* Adjust to CI debugging

* fix CI adjustment

* Further CI adjustments

* Revert CI adjustments

* Temporarily comment test_staggered_restart_with_epochs out

* Increase request timeout and uncomment staggered restart test

* Handle External message kind

* MessageKind uses HasEpoch trait

* QuorumProposal2 has an epoch field

* Consistency task checks nodes in relevant epochs

* QuorumProposal2 now implements HasEpoch

* Fix compiler error

* Cleanup

* fix consistency_task

* Revert "QuorumProposal2 has an epoch field"

This reverts commit 61e1661bcaa513f7cc9f705c20a49551ab38256b.

* Fix cargo audit

Subject: [PATCH 1381/1393] Adapt VID request / response to epochs (#4106)

* Add crash CDN test with epochs

* Initial commit

* Sent to self even when network down

* Check if VID share exists

* Request VID share only if we need it

* Cleanup

Subject: [PATCH 1385/1393]  #4045 re-enable epochs tests with dynamic quora
 (#4103)

* #4045 re-enable epochs tests with dynamic quora

* Epoch 1 is genesis epoch (#4112)

* #4045 re-enable epochs tests with dynamic quora

* Remove Epoch 0

* Allow dead code for genesis method for EpochNumber

The method is not called at the moment but it's better
to have it because otherwise the default genesis method
returning 0 might be called by accident.

* Adjust test_genesis_epoch_from_version

Subject: [PATCH 1389/1393] Fix failing tests

We were sometimes decoding as the wrong type. This adds a function that
decodes to the old VID type if deserializing the new type fails. I think
we want a better solution but this does at least fix the tests for me.
