Inter-Blockchain Finality (IBF) represents a mechanism ensuring irreversible transaction confirmation across disparate blockchain networks. Unlike probabilistic finality, common in Proof-of-Work systems, IBF aims for deterministic finality, guaranteeing that once a transaction is finalized, it cannot be reverted. This is achieved through a committee of validators who collectively attest to the validity and order of transactions, creating a globally consistent state across participating chains. The core principle revolves around a Byzantine Fault Tolerance (BFT) consensus protocol, providing a robust framework for achieving this cross-chain immutability.
Architecture
The architectural foundation of IBF relies on a shared sequencer and a committee-based voting system. Each participating blockchain designates a set of validators who form the IBF committee. This committee observes transactions across all connected chains and, through a BFT consensus algorithm, collectively decides on the order and finality of these transactions. The sequencer aggregates these finalized transactions and propagates them to each blockchain, ensuring consistent state updates.
Algorithm
The underlying algorithm typically employs a variation of BFT, such as Tendermint or HotStuff, adapted for cross-chain operation. These algorithms require a supermajority of validators to agree on the next block’s state, preventing malicious actors from disrupting the finality process. The algorithm incorporates mechanisms for validator rotation and slashing to incentivize honest behavior and penalize misbehavior, bolstering the system’s security and resilience. This ensures that the finality decision is robust against various attack vectors.
