Finality

What is finality?

Finality in blockchain pertains to the irrevocable verification of a transaction or a group of transactions. In traditional financial systems, once a transaction is verified, it cannot be reversed. Similarly, achieving permanence on a blockchain network guarantees that a transaction is unalterable once it is included in the blockchain. This concept is essential for ensuring the security and authenticity of the blockchain. The use of consensus in the blockchain network enables the achievement of finality. Various consensus algorithms are utilized by different blockchain networks, each employing a distinct method to validate transactions and ensure finality. Examples of these algorithms include proof-of-work (PoW), proof-of-stake (PoS), and practical Byzantine fault tolerance.

Finality of Xenea Blocks

In Xenea, blocks are generated every 60 seconds. The finality of a transaction is reached not merely when the block is created, but when the transaction is validated and signed by an Escrow Node. At that moment, the transfer becomes irreversible.

This design ensures that users can rely on the permanence of confirmed transactions while maintaining efficient block production and secure consensus.
