A new libp2p branch was create for that https://github.com/status-im/nim-libp2p/tree/b2eac7e-and-revert-c6aa085 - https://github.com/status-im/nimbus-eth2/pull/5549 - new Issue #975: CI workflow is failing frequently, https://github.com/status-im/nim-libp2p/issues/975, https://github.com/status-im/nim-libp2p/tree/fix/ci-workflow-stability - in progress: PR #968: fix: move workflows for Nim Devel and legacy i386 from "Daily" - new workflows "Daily - Devel" and "Daily - Legacy Platforms" https://github.com/status-im/nim-libp2p/pull/968 - Issue #972: Daily workflow could fail randomly with [OSError] https://github.com/status-im/nim-libp2p/issues/972 ### vac:tke: ### vac:dst: - `wakurtosis:vac:retrospective-rlog` - Reviewed comments; soon to publish - `wakurtosis:vac:rlog` - Analysis of new Wakurtosis simulations regarding the 600 nodes anomaly - Analysis of K8 simulations regarding the 600 nodes anomaly - `analysis-shadow:vac:shadow-gossipsub-analysis` - worked on Topology slices - (added more RAM to the server) - `analysis-shadow:waku:shadow-waku-relay-analysis` - Run 600 nodes NWaku Shadow simulations with and without load - `analysis:nomos:simulation-analysis` - The network delay/bandwidth tuning, readjusting the probabilities, none of them helped. The bug(s) cannot be side-steped in any meaningful way. - New issue: for > 10 views, the disk usage blows up. *1.7 TERABYTES*; and the output is just text files! This was quite unexpected; we now have yet another scalability issue with the nomos sim. - spent couple of days on the Rust code and worked on adjustments. None of them helped with the bug. - `analysis-gsub-model:vac:refactoring` - Tuned/cleanedup to the control messages code - `eng-10ktool:vac:bandwidth-test`: - Machines are no longer blocked - Added Kubernetes network policies to void having machines blocked. - 600 node simulations with Kubernetes to try to replicate 0 rate anomaly (https://discord.com/channels/864066763682218004/1163414326934257684/1170039531500740718) - Started an aproximation of waku-simulator with Kurtosis - Meeting with Slava to investigate prometheus dropping container labeling information - `software-testing:waku:test-automation-js-waku` - Helped Danish with implementing the testing part of a Static Sharding [PR](https://github.com/waku-org/js-waku/pull/1697/commits/762bc5ad6ecad1d41a4aa6ca9bd6e2832a4779ee) - `vac:dst:software-testing:waku:test-automation-interop-testing` - First [PR](https://github.com/waku-org/waku-interop-tests/pull/1#pullrequestreview-1714207334): - start/stop waku docker nodes and connect them in a network - send RPC or REST API calls and validate that messages are reaching the peers - setup ci runs (on pr, on demand and nightly) via github actions - allure [reports](https://waku-org.github.io/waku-interop-tests/4/) via github pages that contain test and docker log attachments for failing tests - automated linting and code formatting - 2 basic tests for now but will extend after the initial set of reviews - `software-testing:waku:test-automation-nwaku` - Moved most of the PRs, missing one. - Implement some store tests. - Found (and fixed) issue with default values encoding/decoding for HistoryQuery. - bug: `assert false` SEGFAULT. - It only triggers on some files, and imports don't seem to be related. - bug: Stopped filter node can receive messages - It's actually expected behaviour. - [Issue](https://github.com/waku-org/nwaku/issues/2178) - bug: Filter doesn't receive messages after subscribing and restarting - [Issue](https://github.com/waku-org/nwaku/issues/2175) - `software-testing:waku:test-automation-go-waku` - Wrote 4 tests related to filter unsubscribe and closed the PR https://github.com/waku-org/go-waku/pull/855 ### vac:acz: - `rlnp2p:waku:rln-doc-and-outreach` - Make changes as per review on rlog - `admin/misc` - Study the research paper on the Reinforced Concrete hash function. - Implemented Reinforced concrete in huff - https://github.com/rymnc/reinforced-concrete-huff - tl;dr: lesser gas consumed than poseidon (2 inputs) - RC hash writeup on vacp2p/research - https://github.com/vacp2p/research/pull/196 - `secure-channels:waku:ethereum-chat` - Keep working on the comments from the team and finish the raw RFC. - https://github.com/vacp2p/rfc/pull/626 ### vac:sc:: - `status:community-curation-contracts` - Adjusted import remappings - https://github.com/status-im/community-dapp/pull/95 - Added Goerli OP deployment config - https://github.com/status-im/community-dapp/pull/96 - Deployed contracts on Goerli OP - Verified contracts on OP Mainnet - `vac:maintainance/misc` - Deployed OP SNT on Goerli OP - Created a few screen casts on deployment - https://www.notion.so/f24bc8154bfd4757989216dde0f50af0?v=eb8f6f301de94f4889ee6179d16eaf47 - Implemented SNT V2 which will be used to make SNT available on Sepolia - https://github.com/status-im/status-network-token-v2/pull/1 - `codex:review-codex-contracts` - finished watching the call recording - reviewed the code again based on the knoledge from call - sent PRs based on our review - https://github.com/codex-storage/codex-contracts-eth/pull/73 - https://github.com/codex-storage/codex-contracts-eth/pull/74 ### vac:nescience: - `state-separation:vac:state-separation-doc` - Keep researching techniques for harmonizing UTXO and based-account model for state separation -> Model to model adapter (Goal 1) - Privacy-enhancing: Prepare document comparing Dory and IPA polynomial commitment schemes. - Research ring signatures that use Dory and IPA. - `proofsystems:vac:research-existing-proof-systems` - Researching techniques for proof creation and verification for Nova.
