Latest news about Bitcoin and all cryptocurrencies. Your daily crypto news habit.
Dencun (Cancun + Deneb) upgrade
- Latest all core devs – consensus (ACDC) call video. Notes from Christine Kim:
- Testing continues on devnet-8
- Devnet-9 planned for Tuesday September 19
- EIP4844 blobs per block: big block analysis presented, no changes to 3/6 (target/max) yet
- Proposed addition to Dencun (open for community input): max epoch churn limit as a short term fix to validator set size growth, discuss on ACDE whether to include in Dencun
Centralization watch: threatening the value of your ETH
- Lido at 32.4% is 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 & Lighthouse 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
- Mempool dumpster: exports transactions from EL node transaction pools in Parquet & CSV format
- MEV-Boost:
- Strong builder identity: proposal to combat imposter attacks (Titan had an imposter)
- Prestwich: proposers & builders could collude on gas limit to minimize base fees
- Whisk devnet: proof of concept Single Secret Leader Election (SSLE) on fork of Lighthouse + Geth
For Stakers
- Staking directory: adds info for liquid staking on network share & self-limit pledges
Client releases for Holešky testnet
- Consensus layer:
- Execution layer:
- Besu v23.7.2
- Erigon v2.49.0
- Otterscan v2.0.0 alpha: adds in-node token indexers
Research
- Terence’s EIP4844+ (ideas for extending blobs after Dencun upgrade): erase code to increase target/max blobs to 6/12 and apply data availability sampling
- PeerDAS: data availability sampling approach reusing p2p components to scale without DHT
- Barnabe: inclusion list games, builders may be incentivised to stuff blocks and proposers may try to bribe/extort each other
Layer 2
- Base delay in block production for 45 minutes
- Barry Whitehat’s Plasma Free proposal: free transactions but if data is unavailable users need to make a forced transaction (users online assumption)
EIPs/Standards
- EIPs
- EIP7514: Add max epoch churn limit
- ERCs (application layer):
- ERC7507: Multi-user NFT extension (ERC721 extension)
- ERC7508: Dynamic onchain token attributes repository
- ERC7509: Entity component system
- ERC7510: Cross-contract hierarchical NFT (ERC721 extension)
- ERC7511: Minimal proxy contract with PUSH0
- ERC7512: Onchain representation for audits
- ERC7513: NFT-bound modularized contract (ERC1155 extension)
