Taiko Alethia ¹

A zkEVM that lets Ethereum validators sequence your transactions directly — no middleman sequencer collecting fees or deciding transaction order. Every Ethereum validator can propose Taiko blocks, making censorship nearly impossible.

Key Difference: L2 that can't be shut down — since Ethereum itself sequences transactions, it keeps running as long as Ethereum exists, unlike other L2s that fail when their sequencer goes offline.

Best for: Projects requiring unstoppable operation, DeFi protocols avoiding sequencer risk, developers wanting exact Ethereum behavior without modifications.

Technical: Type-1 zkEVM with based sequencing, permissionless proving, preconfirmations for fast UX, no separate consensus layer.

• Use Cases

  • DeFi infrastructure: Ritsu DEX with Rhythm AMM, Meridian Lend, Avalon Finance
  • Bitcoin on Ethereum: SolvBTC bringing native Bitcoin liquidity to L2
  • Censorship-resistant apps: Leverage based sequencing for unstoppable operation
  • Gaming and high-frequency trading: Preconfirmations enable responsive UX

• Security & Data Availability

  • Every block validated via ZK proofs; no fraud windows or optimistic fallback.
  • Based rollup design: any Ethereum validator can propose blocks, ensuring open participation.
  • Posts calldata directly to Ethereum using blob transactions (EIP‑4844).

• Infra & Execution

  • Bytecode-equivalent with Ethereum — supports full opcode set, gas model, and state hashing.
  • Permissionless block proposing and proving — anyone can participate.
  • Preconfirmation system delivers fast transaction times while staying decentralized.

• Performance

  • Preconfirmations provide ~2 second transaction acknowledgment.
  • Final settlement follows Ethereum L1 cadence for maximum security.
  • No artificial TPS cap, constrained by Ethereum blob space and proof generation.

• Trade-offs

  • Smaller ecosystem vs established L2s — less liquidity and fewer integrations.
  • Based design limits MEV extraction opportunities compared to centralized sequencers.
  • Type-1 zkEVM prioritizes compatibility over proof speed — slower than custom VMs.
  • Proving infrastructure still bootstrapping toward full decentralization.
