Eth News and Links
Dencun (Cancun + Deneb) upgrade
- Latest all core devs – execution (ACDE) call video. Recap by Tim Beiko. Notes from Tim Beiko and Christine Kim:
- Devnet 8 to be used for most Dencun testing, devnet 9 will include final spec changes & hopefully be the last devnet
- Public testnet upgrade order: Holešky (new, smaller number of node operators), Goerli (deprecated, has most apps/L2s/stakers) and then Sepolia before mainnet
- Holešky to test 3/6 (target/max) blobs with option to reduce to 2/4 for other testnets/mainnet
- Discussions on Verkle trie live migration vs combining with state expiry and Address Space Extension/Compression
- Intro to blobspace: EIP4844 (proto-danksharding) in Dencun upgrade & full danksharding
Centralization watch: threatening the value of your ETH
- 🚨🚨🚨 Lido very close to breaching 33% threshold
- Client diversity (via clientdiversity.org):
- Execution layer: Geth supermajority, could possibly cause a chain split
- Consensus layer: two clients over 33%, a bug could mean loss of finality
- Needed: more geographic diversity for both stakers and nodes, particularly outside of US/Can/EU
Layer 1
- Ethereum Execution Layer Specification (EELS): Python reference implementation (similar to consensus layer Python spec)
- Grant available to update Yellow Paper with missing pre-merge fork logic
- Erigon Caplin (CL client) roadmap
- Dapplion: Whisk bootstrapping, tradeoffs of bootstrapping strategies
- Otterscan v1.32.0: adds contract interaction (for Sourcify verified contracts)
Client releases
- Consensus layer:
- Lodestar v1.11.0: adds Holešky testnet
- Execution layer:
- Nethermind v1.20.2/v1.20.3: adds Holešky testnet
- Reth v0.1.0-alpha.8: sub 1TB full node, configurable pruning for each table and improvements for Transaction Pool & RPC
Research
- Decouple attestation weight from attestation rewards, proposal to reduce risks from liquid staking
- Cumulative non-expiring inclusion lists, add-on to inclusion list design
- Slashing penalties if max effective balance increased (EIP7251), proposes initial penalty be a constant or scale sublinearly and correlation penalty be modified to scale quadratically
- PEPC-DVT: Protocol-Enforced Proposer Commitments without changing consensus
Layer 2
- Arbitrum Stylus: build apps for Nitro chains in Rust, C & C++, live on testnet
- Polygon Chain Development Kit (CDK): launch a rollup or validium
- StarkWare Stone prover open sourced
EIPs/Standards
Check out Evan’s new podcast: web3 Builders
Are the permabulls lying to you (for clicks and views) about the chances for ETF approval?
Evan says they are, Will disagrees.
