Bitcoin Signature Verification Tool

Verify the authenticity of Bitcoin address signatures. Enter the message, signature, and address to verify ownership.

How Bitcoin Signature Verification Works

Bitcoin signature verification uses cryptographic principles to prove ownership of a Bitcoin address. When you sign a message with your private key, it creates a unique signature that can only be verified using the corresponding public key (derived from the Bitcoin address).

This tool verifies that the signature was created by the private key associated with the provided Bitcoin address. The verification process:

  1. Derives the public key from the Bitcoin address
  2. Recovers the message hash from the signature
  3. Verifies the signature using the public key
