A verification protocol is a set of rules or procedures that ensure the accuracy and validity of data in a blockchain network. It primarily focuses on confirming transactions and maintaining the integrity of the ledger.When a transaction is initiated, it needs to be verified by multiple participants in the network, often referred to as nodes. These nodes check the authenticity of the transaction against the existing data on the blockchain. Once validated, the transaction is added to a block, which is then appended to the blockchain.There are various types of verification protocols, such as Proof of Work (PoW) and Proof of Stake (PoS). PoW requires participants to solve complex mathematical problems to validate transactions, while PoS allows validators to create new blocks based on the amount of cryptocurrency they hold and are willing to “stake.”Ultimately, a verification protocol plays a critical role in preventing fraud and ensuring that only legitimate transactions are recorded, helping to build trust in the system.
