TypeAlias.Hash

type Hash: `0x${string}`;

Represents a cryptographic hash value in hexadecimal format.

Remarks​

A Hash is typically a 66-character hexadecimal string used to uniquely identify transactions, blocks, or other data in the blockchain. It is the result of a hash function (like SHA-256 or Keccak-256) applied to some data.

Format:

  • Prefix: Must start with "0x".
  • Length: Usually 66 characters (including the "0x" prefix), representing 32 bytes of data.
  • Characters: The following characters should be valid hexadecimal digits (0-9, a-f, A-F).
  • Example: "0x5e1d3a76f95b1f9ed1e7f8e0e9a2b2e4b6d4c8d5e3a7b9f1c2d3e4f5a6b7c8d9"

Usage: The Hash type alias ensures that any variable representing a hash value conforms to the expected format. Hashes are used throughout blockchain operations to reference specific transactions, blocks, or data.

Common Use Cases:

  • Transaction Hashes: Identifying specific transactions on the blockchain.
  • Block Hashes: Referencing specific blocks in the blockchain.
  • Data Integrity Checks: Verifying that data has not been tampered with by comparing hash values.
