Ethereum Cat Herders Update #38

YOLO v3, Berlin, EIP-1559, Eth2.0 updates, EIPIP meeting, 1559 community call, and more.

Welcome to another edition of the Ethereum Cat Herders community update to bring you up to speed since the last update.

Ethereum 1.0

Ethereum All Core Developers’ meeting

YOLOv3 & Berlin client updates

• Fuzz testing can start this week.
• The difference between the YOLO & Berlin testnet will be the tx load, no other change is expected. YOLO is mining empty blocks and not sending tx in the present n/w.
• Berlin Testnet — Feb 24th (tentative). Clients will be ready by the next ACD to fork the testnet.
• The block# on different testnet will be discussed in the ACD Discord, this week.
• Berlin on mainnet — March 24th (tentative)
• The mainnet block # will be discussed in the next ACD meeting.
• Network Upgrade Survey. Consider taking the time to answer this survey to help us plan future upgrades for Ethereum 1.0.

EIP-2481: eth/66: request identifier

• No change in EIP-2481 except Martin will improve the one-line statement in the EIP as suggested by Peter S.

EVM 384

• Paul D provided an update for EVM 384 followed by some questions by Alex Vlasov. Worth listening to the conversation.

EIP-1559: Fee market change for Ethereum 1.0

• Tim shared the State test preliminary result, it looks good.
• It was the first dry run of the test. Besu & Geth participated. Spammed the testnet with a large amount of tx.
• Next week more proper test will happen with Nethermind along.
• Suggestions on metrics that people will like to see

— Decrease the amount of empty block in every mining

— Network latency?

— Have different regions to small simulate the main net.

— concerns about the empty block rate and uncle rate

• ACD meeting #105: agenda, video, Tim’s tweet, notes. The next meeting is scheduled for February 19, 2021, at 1400 UTC.

Eth1.0 Clients update

• Geth — Marljeh (v1.9.25)
• OpenEthereum — v3.1.1
• Besu — 21.1.0-RC1 — Added chainId, publicKey, and raw to JSON-RPC api calls returning detailed transaction results.
• TurboGeth — 2021.02.01-alpha— fix for the data corruption after a network interrupt & MDBX stability.
• Nethermind — v1.10.17. A for fixes for xDAI, JSON RPC, CONFIG, & EIP1559 - Stopped basefee calculations when EIP-1559 is not enabled.
• Ethereum JS — @ethereumjs/tx v3.0.1

Ethereum 2.0

Eth2.0 mainnet

• Eth2 Core Teams Workshop: Sharding and Eth1+Eth2 Merge
• A lot of slashings reported over the past two weeks on the mainnet for Prysm clients. Slashing prevention tips here: https://medium.com/prysmatic-labs/eth2-slashing-prevention-tips-f6faa5025f50.

Eth2.0 Clients’s update

• Nimbus-eth2 — v1.0.7— New slashing protection mechanism (doppelganger detection) prevents your validator from contradicting itself if you have accidentally left it running on another machine. Optimized batching of BLS signature verification leading to faster sync speeds and reduced CPU load.
• Lighthouse — Dr. Wong
• Lodestar — Release v0.15.0 — Implemented hard fork compatible DB, fix httpClient error formatting. Fix validator not found and wrong events URL. Replace all mentions of Medalla (and any other dead testnets) with Pyrmont. Initial sync as state machine. Unify EpochContext.
• Prysm — v1.2.0 — This release includes significant improvements and a much-awaited feature of slashing protection import and exports, standardized with EIP-3076 and compliant with other eth2 clients. Updating to this release is recommended to avoid missed attestations. This PR also implements more API endpoints from the eth2 standard API.
• Teku — v21.1.1—Added --validators-external-signer-public-keys arguments can now include URLs to load the public keys from. The URL should provide a list of public keys as a JSON array. Added support for block, attestation and voluntary_exit event streams from the standard REST API.

EIPIP working group

• EIPIP meeting #25: agenda, video, notes.
• The next EIPIP meeting is scheduled for February 10th at 1500 UTC. Agenda.
