Terminology

This page provides clear definitions of key rollup-related terms, particularly those associated with bonding mechanics in the Taiko Alethia protocol.

Bonding Mechanisms in Taiko Alethia

Bonding is a fundamental mechanism in the proving and verification process of Taiko Alethia. Bonds ensure that provers remain accountable for their commitments.

Liveness Bond

  • A bond posted by the initially assigned block prover to guarantee that they will submit the first proof within the required proving window.
  • Purpose: Ensures that the assigned prover remains active and submits the initial proof within the allocated time.
  • Lifecycle:
    1. The L2 block proposer submits a block via proposeBlock on Ethereum L1.
    2. The assigned prover locks a Liveness Bond to signal commitment.
    3. If the prover submits the proof within the proving window, the bond is refunded.
    4. If the proof is not submitted within the proving window, another prover can step in.

Key Takeaways

  1. Liveness Bond ensures that the initial prover submits their proof on time.
