Hashcash, as a precursor to modern proof-of-work systems, was designed to mitigate denial-of-service attacks. By imposing a computational cost on the sender, it discourages the sending of unsolicited messages or requests.

The algorithm works by requiring the sender to find a nonce (a number used once) that, when hashed with other input data, results in a hash value that meets certain criteria. This process is computationally intensive and time-consuming.
