    Usage

    npm install bitcoin-util

    Methods

    toHash(hex)

    Takes a hex string that contains a Bitcoin hash as input, and returns a Bitcoin-protocol-friendly little-endian Buffer. Throws an error if the hex string is not of length 64 (representing a 256-bit hash).

    compressTarget(target)

    Converts the difficulty target target to its compact representation (used in the "bits" field in block headers). target should be a Buffer (little-endian, the zeroes should be at the end). Returns a number.

    expandTarget(bits)

    Converts the compressed target integer bits to its target hash representation. Returns a Buffer.
