Dencun (Cancun + Deneb) upgrade (meta EIP7569)

Centralization watch: threatening the value of your ETH


  • 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
