What is blockchain ID code?

A blockchain represents a revolutionary way of maintaining records. It functions as a distributed ledger, which means the data is not stored in a single location.

This ledger grows over time as new records, known as blocks, are added to it. Each block is securely linked to the previous one through cryptographic hashes. This ensures that the data cannot be tampered with or altered.

Within each block, there is a cryptographic hash of the preceding block. This acts as a unique identifier that ties all the blocks together in a chain. It guarantees the integrity of the data and its sequence.

Additionally, each block contains a timestamp. This provides a historical context to the transactions recorded within the block, allowing users to trace the evolution of the blockchain.

The transaction data within each block is typically represented in a format called a Merkle tree. In this structure, data nodes are represented by leaves, which are then hashed together to form parent nodes. This process continues until a single root hash is generated, representing the entire set of transactions.
