The Unbreakable Chain

This is a live simulation of a blockchain with Proof-of-Work mining. Each block is cryptographically linked to the one before it. Try changing the data in any block to see it turn red (invalid). Then click "Mine Block" to find a valid nonce and restore the chain's integrity. Notice how mining one block invalidates the next block, demonstrating the cascading nature of blockchain security.
