The verifier is responsible for ensuring that the information on the blockchain is accurate and up to date. They do this by verifying new transactions and adding them to the blockchain.

Q: Who verifies data in blockchain?
A: There is no one central authority who verifies data in a blockchain. Instead, data is verified by the network of computers (or nodes) that make up the blockchain.
Q: How does blockchain verify identity?
A: There is no one definitive answer to this question, as the verification process can vary depending on the particular blockchain platform being used. Generally speaking, though, blockchain platforms use a combination of public and private key infrastructure (PKI) and cryptographic hashing to verify identity. With PKI, each user is assigned a unique public and private key pair, which are used to encrypt and decrypt data. The private key is kept secret, while the public key is shared with the network. When a user wants to send data to another user, they use the recipient’s public key to encrypt the data, and then the recipient uses their private key to decrypt it.
Cryptographic hashing is used to create a unique fingerprint for each block of data on the blockchain. This fingerprint can then be used to verify that the data has not been tampered with. When a user wants to add a new block of data to the blockchain, they first compute the hash of the data. They then send this hash, along with the data, to the network. Each node on the network then verifies the data against the hash to make sure that it has not been tampered with. If the data is valid, the node will add the new block to the blockchain
Q: How do I verify a blockchain transaction?
A: There are multiple ways to verify a blockchain transaction. One way is to use a block explorer, which is a website that allows you to view all the details of a particular blockchain transaction. Another way is to use a Bitcoin wallet that allows you to view all the details of a particular blockchain transaction.
Q: What does a validator do?
A: A validator is a software tool that checks the accuracy and quality of data. It can be used to check the validity of data entered into a database, or to check the accuracy of data extracted from a database.
