Vac 2024/03/04

vac:p2p:

• nimlibp2p:vac:webrtc-transport
  • Sctp and Dtls client done: https://github.com/status-im/nim-webrtc/pull/5
  • Adds a lot of comments some refactoring to improve (I hope) the readability https://github.com/status-im/nim-webrtc/pull/6
  • Closing the streams/connections: starts to test and think about it to make it bulletproof
• nimlibp2p:vac:maintenance
  • Investigating issues related to https://github.com/status-im/nim-libp2p/pull/1032

vac:tke:

• nomos:tdc-objectives
  • expanded the objectives & requirements part of the TDC (@Frederico)
• codex:cdx
  • incorporated into Codex Litepaper all material about Codex on GitHub (@Frederico)
  • reviewed the causal loop diagragam for Codex (@Frederico)
  • reviewed the stock and flow diagram for Codex (@Frederico)
• waku:rln-membership:
  • Prepare a summary of the RLN membership model including user journey mapping (@Martin)
  • Review the pricing of Farcaster, etc. (@Martin)
• waku:general-incentives
  • Follow up with general research into Waku strategy based on the IFT strategy call. (@Martin)
• status:SNT-staking
  • Continue the review of the staking contract (@Martin)
  • Understand the severity of precision loss (due to Solidity constraints) and resulting discrepancy between the contract logic and radCad simulations (@Martin)
  • Assist the SC team in further checks and definition of testing scenarios (@Martin)

vac:dst:

• eng-10ktool:vac:bandwidth-test
  • Work on plotting module in the Kubernetes framework
    • Modified main yaml to add plotting options
    • Created plotter class to group there all functionalities
    • Structured plotter to be able to group several experiments in same plot in an automatic manner
  • Lots of calls with Wings to test the lab, launch simulations, discuss about problems and so on.
• Deployed iBGP for Calico
  • Which got the IP addresses wrong at first, fixed by editing Node annotations
  • Later removed BGP due to numerous issues with it
• Numerous, numerous Kubernetes tests and improvements
  • Tried Cilium briefly
  • Switched from Cilium to Calico
  • Reinstalled entire cluster as Calico transition broke things (due to CNI switch without reinstall being a bad idea)
• Scale testing revealed that Linux has limits per node that prevent us from scaling beyond about ~1400 waku nodes per physical host when running on bare metal
• Created a new architecture for running tests
  • Hybrid between bare metal and virtualised Kubernetes
  • Rook-Ceph (Storage) and Prometheus-Thanos (Metrics) stacks run on bare metal, as does all management
  • The rest runs in a KubeVirt based deployment system.
    • We deploy what we're calling "opal fragments" (fractions of the Opal Kubernetes cluster) - Kubernetes workers dedicated solely to running nwaku deployments.
  • Can deploy 5000 nodes in < 8 minutes, with stable mesh forming around 25 minutes into deployment
• Experimented with various opal fragment deployments - 56x nodes seems to be the most stable configuration
  • Much higher than this (especially with poor allocation of cores) causes instability in the CNI (Calico)
    • Which causes monitoring issues as nodes drop out of Prometheus monitoring
    • And can mess with the mesh
  • Instability is lower with lower # of connections
• Debugging CoreDNS issues - believe we've found a bug in CoreDNS and its interactions with HeadlessServices, returning NXDOMAIN even for valid hostnames about 1 in 5.5 to 6 queries.
• Ran repeated simulations to get a stable simulation for testing.
• Built a new "accelerated bootstrap" mode for simulations

  • Merged PR-1027, PR-1028 and used TxTime sorting on SendPeerList. Additionally used semaphors to limit simultaneous transmissions. Improves results in some cases and shows large fluctuations in other messages
  • Configured shadow simulation for variable latency and bandwidths. Trying to build some automated scripts (requires adding edges among all peers, and adding all nodes with variable latency/bandwidth). NetworkX package in python can help writing network in gml format
