Latest news about Bitcoin and all cryptocurrencies. Your daily crypto news habit.
Dencun (Cancun + Deneb) upgrade (meta EIP7569)
- No core devs call this week, next all core devs – execution (ACDE) call January 4
Centralization watch: threatening the value of your ETH
- Lido at 31.62% is far too close to 33.3% threshold
- Client diversity (via clientdiversity.org):
- Execution layer: Geth ~84% supermajority, could possibly cause a chain split
- Consensus layer: Prysm 41%, any client bug over 33.3% could mean loss of finality
- Better geographic diversity is optimal, particularly outside of North America & Europe
Research
- Vitalik’s Proof of Stake simplification proposal, 3 approaches to cap signatures to 8192 per slot:
- DVT: 4096 validators with minimum 4096 ETH deposit, solo stakers join DVT pools
- Two-tiered staking: heavy layer (4096 ETH min deposit) finalizes and light layer (no min deposit) attests, heavy layer + 50% or more of online light layer to finalize a block
- Rotating participation: randomly choose 4096 active validators, incentive weight decoupled from consensus weight
- Execution tickets (previously Attester-Proposer Separation): in-protocol ticket market, lottery to select beacon block proposer & attesters and lottery to select execution block proposer & attesters
- Blob DA scaling overview: up to 128 blobs via 1D PeerDAS, then increase up to 256 blobs via 2D PeerDAS or full Danksharding
MEV
- MEV-Boost auction model and bidding strategies (naive, adaptive, last-minute & bluff bidding) show reducing latency optimizes builders performance
- Rekt: $1.3M paid to solo validator by searcher after user error adding liquidity
Layer 2
- zkSync Era network issues post-mortem: safety procedure caused sequencer to wait for computed state update mismatch to be resolved
EIPs/Standards
- EIPs
- EIP7581: Increase block gas target and gaslimit
- ERCs (application layer):
