Finalized state refers to a point in the blockchain where a transaction or block is considered permanent and irreversible. Once a block is added to the blockchain and confirmed by the network, it reaches this state. This means that the transactions within that block cannot be altered or undone without a significant amount of computational power, making it secure.The process of reaching a finalized state often involves consensus mechanisms, ensuring that a majority of network participants agree on the validity of transactions. Different blockchain systems may have varying criteria for finality, such as the number of confirmations a block must achieve.Achieving a finalized state is crucial for instilling confidence among users, as it guarantees that once a transaction is completed, it is reliably documented. This reliability is fundamental for applications such as payments, smart contracts, and decentralized finance, as it allows users to trust that their transactions are accurate and secure.
