Because each block contains a unique code called a hash—along with the hash of the previous block—altering any information on a block would require changing every subsequent block on the chain. While the transaction details are visible, the identities of the people involved are represented by cryptographic addresses rather than personal information.

This sequential linking is what gives the technology its name and ensures that the history of every transaction is permanent and traceable. When a new block is filled with data, it is securely linked to the previous block using complex cryptographic principles.
In contrast, a blockchain network operates on a peer-to-peer basis where every participant, or node, holds a copy of the entire ledger. This is often achieved through methods like Proof of Work or Proof of Stake, which require participants to solve complex puzzles or stake their own resources.
