Digital Credentials and Blockchain Technology
Digital Credentials can use blockchain technology to ensure their authenticity and security. Blockchain technology is a distributed ledger system that uses cryptography to ensure data integrity. It works by creating blocks of data that are linked together using cryptography. Each block contains a set of data, a hash of the previous block, and a hash of the next block. Hashes are unique values used to ensure data integrity.
When a digital credential is issued using blockchain technology, the credential data is recorded in a block. The hash of this block is included in the next block, and so on. This creates a chain of blocks that is impossible to modify without altering all subsequent blocks.
