Eth News and Links

Mainnet execution layer

  • Latest core devs call video. Notes from Tim Beiko & Christine Kim:

    • Shanghai upgrade planning: append withdrawals in block headers, discussed if EIP1153 (transient storage opcodes) should be included
    • Goerli supply inflation discussion

Proof of Stake consensus layer

PoW switch off (the merge)

  • Reminder of what to expect from the merge, fees go to block proposers, withdrawals in Shanghai, 12s block times, no fee reduction, stakers need to run EL client, transition trigger is TTD and don’t need ETH to run a node
  • Details of how withdrawals spec has evolved: push-style withdrawals, managed by the consensus layer, processed by the execution layer
  • Alchemy’s Kiln testnet faucet



  • Optimism calldata compression: how to decompress Layer 2 transactions
  • Rollup centric future rather than cross-chain as bridges are single point of failure and introduce contagion risk for the destination chain
