Latest news about Bitcoin and all cryptocurrencies. Your daily crypto news habit.
Dencun (Cancun + Deneb) upgrade
- Latest all core devs – execution (ACDE) call video. Recap by Tim Beiko. Notes from Tim Beiko and Christine Kim:
- Testing continues on devnet-8 and MEV-Boost workflows on kurtosis
- Max epoch churn limit (EIP7514) added to Dencun, the maximum new stakers per epoch will be set to 8;
Dankrad: EIP7514 gives time to deal with economic/tech consequences of Lido attack - BLOBBASEFEE opcode (EIP7516) for L2 fee calculations added to Dencun
- EIP4788 (beacon block root in EVM) being updated with changes from audits
- Devnet-9 to include EIP7514, EIP7516 & EIP4788 changes, ACDC to set launch date
- Reth intro: EL client in Rust, hoping to join devnet-9
Centralization watch: threatening the value of your ETH
- Lido at 32.3% has reduced slightly but still very close to breaching risky 33% threshold
- Client diversity (via clientdiversity.org):
- Execution layer: Geth supermajority, could possibly cause a chain split
- Consensus layer: Prysm over 33%, a bug could mean loss of liveness
- Need more geographic diversity for both stakers and nodes, particularly outside of US/Can/EU
Layer 1
- Epoch churn limit increased from 11 to 12 (EIP7514 in Dencun sets to 8 for deposits)
- MEV-build-rs alpha: MEV-Boost builder in Rust, extends Reth (EL client)
For Stakers
- Lodestar incentive program results, 86 validators to share $25k
- Geth node running on NanoPC-T6 ($129 board), synced in 13 hours
- Secure-signer (alpha): remote-signing inside hardware enclave
- Tor Push: proof of concept for validator privacy, push messages into gossipsub via Tor
Client releases
- Consensus layer:
- Nimbus v23.9.0: Holešky testnet support and simplified config for remote signers
- Execution layer:
- Geth v1.13.0: pruning reimplemented using path based storage (needs a resync)
Research
- Streamlining fast finality: single proposal and voting phase per slot using strong confirmation
- Two-tiered staking: native liquid staking design
