Interactive proof-of-work simulator

This page only simulates local hash search inside the browser tab. It does not connect to a blockchain, a pool or a real wallet.

Important: the wallet field is just a label to personalize the session summary. No coins are mined, sent or received.

Session setup

Ready to simulate proof of work without mining a real cryptocurrency.

What this demonstrates

  • Each nonce changes the input string and therefore the resulting SHA-256 hash.
  • Difficulty is modeled as the number of leading zeroes required at the start of the hash.
  • The work happens locally in your tab and stops as soon as a valid demo hash is found.
  • It is a teaching aid to understand proof of work, not a real mining client.
