Bowen to consult with Max on this issue - Arto: similar issue was observed in May - Joshua: 10M accounts size is not working, so need to be reduced to 500k - 1M; 20k accounts works well - Perhaps there're problems with bash script - Bowen: in case the param estimator won't give results then we need to push back the release - Arto: perhaps we need to overestimate the costs and later reduce it (when param estimator is fixed)? - Joshua & Bowen: there're some estimations, but we need to consult with Max on it - AI: - Evgeny Kapun -- to review the updated code - Bowen to consult with Max on estimates & propogate the feedback - Ethereum state prover on NEAR - Update on the state prover development - Evegny Kapun: token metadata won't work as intended - AI: Evgeny Kapun to provide a list of extensions to the current bridge which may help by Monday team call - Tx block execution - https://explorer.testnet.near.org/transactions/5eukZxsNfsyWjFoDyYBdjBD4NogubHHSZTCc1Ejzqvzi - Transaction execution is split over at least two blocks => we need to make sure that nonce changes are observed at right call - There's no upward bound for the finalisation of the transaction - Normally it takes less than 5 blocks - AI: Arto to take care of this next week. Relayers need to re-index all the transactions. This will make possible to roll put the block explorer - DAO approach (Matt) - SputnikDAO supports voting on binary questions, yes/no. We need to support more complex question types, like choosing N of M from an enumerated list. OTOH, SputnikDAO supports things we don't need, like multiple DAOs; we only need one. - Question: Should we fork SputnikDAO, calling it AuroraDAO, tailoring it to our own needs, or try to extend SputnikDAO. The former seems like the right choice: We can move faster, since we can implement in specific ways, rather than having to consider generalized approaches. - AI: Matt/Alex to chat with Illia on the plans on SputnikDAO, previously preparing the requirements. - [Descoped] Bridging new tokens - [Descoped / Read the docs] From Marcelo: https://github.com/aurora-is-near/rainbow-bridge/discussions/597 ## Next week - Ahmed Ali: - TBD - Alex Shevchenko: - Round wrap up - Preparation of EthCC talk - Arto Bendiken: - Support the ETH & ERC-20 connector Mainnet roll out. - Backfill and (re)index the historical block data. - Finish the the block explorer roll out. - Finish the edge infrastructure roll out. - Evgeny Kapun: - Finishing Math API - Tests development - Working on Blake2 - Evgeny Ukhanov: - Rust/NEAR academy. - AuroraDAO development - TBD, Aurora engine issues - Frank Braun: - Tons of infrastructure / security work. - Push `evm-bully` forward. - Get overview of CI/CD, prepare work for Dmitry. - Onboarding documentation. - Joshua J. Bouw: - Continual Berlin HF work. - Math API, addressing Evgeny Kapun comments - Kirill Abramov: - Support and research the new architecture design for ERC-20 connector. - Finish all needed tests and enable them in CI. - Aurora-engine PR reviews & more testing. - Rust/NEAR academy. - Marcelo Fornet: - Testing connectors (infrastructure, automated tests, and cli) - Matt Henderson: - Continue with DAO (first iternation complete) - ERC-20/ETH transfer UI (hopefully) - Start localization infrastructure work - Launch localized version of the blog - Continue assisting with internal process definition - Michael Birch: - Bully fix (continued) - Berlin support (?) - Pierre-Alain Ouvrard: - Release connector libraries and UIs. - Yulian Lavysh: - Coordination of localization - Employee handbook - Content strategy - Recruiting - TBD

Principles of Extreme Ownership

1. Extreme Ownership (p. 29) On any team, in any organization, all responsibility for success and failure rests with the leader. The leader must own everything in his or her world. There is no one else to blame. The leader must acknowledge mistakes and admit failures, take ownership of them, and develop a plan to win. [...] This concept is the number-one characteristic of any high-performance winning team, in any military unit, organization, sports team or business team in any industry. 2. No Bad Teams, Only Bad Leaders (p. 53) When leaders [drive] their teams to achieve a higher standard of performance, they must recognize that when it comes to standards, as a leader, it’s not what you preach, it’s what you tolerate. When setting expectations, no matter what has been said or written, if substandard performance is accepted and no one is held accountable—if there are no consequences—that poor performance becomes the new standard. Therefore, leaders must enforce standards. Consequences for failing need not be immediately severe, but leaders must ensure that tasks are repeated until the higher expected standard is achieved.
