## Vac 2024/02/05
### vac:p2p:
- `nimlibp2p:vac:webrtc-transport`
- Fix a bug in `Datachannel.read` (reading the last message received instead of the first one)
- Fix a bug due to an Sctp delay (set it to 0ms was the solution)
- Find a bug in the conception of WebRTCStream. ReadOnce should be Length-prefixed.
- try to fix it by re-writing ReadOnce, but due to the nature of this proc (inheritance issue) it doesn't work
- write a RawWebRTCStream to make the length readable without issue
- Fix a bug with the endianness of the datachannel protocol id
- E2E Done!
- `nimlibp2p:vac:gossipsub-stagger-send`
- feat: make relayed messages non priority (don't use an explicit queue for priority msgs) - https://github.com/status-im/nim-libp2p/pull/1015
- feat: drop msgs to be relayed waiting for too long in the queue - https://github.com/status-im/nim-libp2p/pull/1015
- `nimlibp2p:vac:maintenance`
- Investigate dependencies issues
- Found possible problem/s
- Lack of versioning
- No major version clamping
- Using #head
- Temporary workaround: Clamp/Pin (to git hash) libp2p dependencies' versions
- [PR](https://github.com/status-im/nim-libp2p/pull/1020)
- Improve documentation [In Progress]
- Building go-libp2p-daemon
- Getting Started
- [PR](https://github.com/status-im/nim-libp2p/pull/1021)
- Merge timeout increase
- Improved `checkExpiring`
- Now it'll outpout an error message when it fails due to timeout
- Not the most visible message
### vac:tke:
- `admin/misc`:
- Matty Handoff document finished and share with team on Wed (@Matty)
- Team Lead Evaluation Criteria finished and share with team on Wed (@Matty)
- Strengths and development areas for Frederico and Martin, shared with Corey, Daniel, and Jarrad (@Matty)
- `codex:economic-analysis`
- finalize all Codex notion including Dragan's comments to litepaper (@Matty)
- Wednesday call with Codex team get in sync on next steps
- `status:SNT-staking`
- staking contract implementation becoming a priority, refresh latest progress with SC team (@Martin)
- `nomos:economic-analysis`
- Reading whitepaper and updating TDC (@Frederico)
- Porting wealth concentration simulation code to GPU to decrease runtimes (@Frederico)
- `waku:economic-analysis`
- Continue Waku Network of Networks design discussion with Franck, concerns around forking (@Martin)
- Research similar abstract p2p validation protocols (e.g. former Keep Network)
### vac:dst:
- `eng-10ktool:vac:bandwidth-test`
- Try to get a stable nim-libp2p version for simulations. Investigated with Alex about building issues with nimble.
- Analized libp2p metrics, everything normal so far
- call with p2p team
- Scale testing for 10K project
- setup go-waku experiment at scale
- Successfully simulated a 2,150 node simulation and gathered some basic metrics
- Modified Kubernetes to allow for more pods to allow for (in theory) scaling to 10k+
- Failed simulations at 10000 and 5000 nodes - current limits seem to be around ~4800 or so
- Prometheus is a definite bottleneck - need to switch to a scaled/sharded Prometheus/***Thanos*** setup
- Attempting one last simulation over the weekend at 4200 nodes
- Diagnosing 10K project bottlenecks
- Identified a major potential bottleneck in the form of control plane traffic going over Wireguard / large packet load over WG causing swarm collapse
- will test the new theory later by re-deploying on Vac Kubernetes with a local control plane + local traffic (while still complying with infra team requirements)
