A finality certificate is a cryptographic proof that a particular block or transaction has reached an irreversible state on a blockchain. This certificate confirms that the transaction is permanently recorded and cannot be altered or reverted, providing a strong assurance of settlement. It is typically generated by a supermajority of validators or by a designated finality gadget within the consensus protocol. This mechanism is crucial for cross-chain communication and financial integrations.
Context
Finality certificates are increasingly important in proof-of-stake blockchains and interoperability solutions, providing assurances for rapid and secure cross-chain transactions. A key discussion point involves the different types of finality, such as economic finality and cryptographic finality, and their implications for security and transaction speed. Future developments focus on standardizing finality mechanisms to facilitate seamless asset transfers across diverse blockchain networks.
This research introduces Accountable Safety, a new PoS property that guarantees finality or provides cryptographic proof of validator misbehavior under minimal synchrony.
