Permanent blocks refer to blocks of transactions that have been added to a blockchain and are considered immutable and irreversible due to the network’s consensus rules and cryptographic security. Once a block is deeply buried under many subsequent blocks, its contents are practically impossible to alter without an overwhelming amount of computational power. This characteristic provides the finality and trustworthiness of recorded data. It forms the basis of blockchain security.
Context
The concept of permanent blocks is fundamental to the security and integrity of all public blockchains, underpinning the trust in digital asset transactions. Discussions often center on the number of confirmations required for a block to be considered truly irreversible. News related to blockchain forks or security incidents sometimes addresses the finality of transactions within different network states.
