• Ethereum Public Goods 🌏
• Fun bounty 💃🏽

What is Taiko

• An Ethereum-equivalent ZK Rollup (a Type 1 ZK-EVM)
• L1 sequenced / "based rollup"
• Fully open source and MIT licensed (community project)
• Fully permissionless block proposing and proving

Block proposing

Deriving blocks

Proving blocks

Verifying blocks

Infrastructure Improvements

Goal: Improve usability

• NFT bridge: ERC20 bridge avaiable already
• ZK optimized bridge: MPT check in circuit, verify ZKP
• ZK additions to blockscout explorer (block proven/verified/…)
• GUI or set-up wizard to help anyone run a rollup node

Protocol Proposing Improvements

Goal: Improve the efficiency of proposing blocks

• Improve block proposing cost estimation
  • L1: proposing a block is free
  • L2: costs depend on L1, time dependent
• "based" sequencer
  • Integrate flashbots, no more anarchy
• Integrate a shared sequencer (or emulate one)
  • Taiko already is fault tolerant for invalid transactions
• Craft a kind of “mev-boost” for Taiko L2

Protocol Economics (no-code bounty!)

Goal: simple and robust

1. Proposer buys L2 blockspace:
   • gas <-> ETH EIP-1559 style, but
     • No fixed block times
     • Block size not dynamic
2. Pay the prover
   • Generally paid by the proposer
   • Trying to find the most efficient prover
     • First to submit: proof time <-> TKO
     • Auction: reserve based on (cost, proof time)
     • PoS: Stake based on any data (incentives!)
