WuTalk has learned that Simon Males posted an introduction to the operating mechanism of Krackpot: this tool utilizes WebGPU to perform secp256k1 elliptic curve calculations, SHA-256, and RIPEMD-160 hashing directly in the browser to search for the private key of Bitcoin Puzzle 71. The key space is approximately 2⁷⁰, and the tested speed of an RTX 4070 is about 44 million keys per second, with an average traversal time of around 430,000 years. Krackpot requires no installation or registration, and the search process does not rely on a backend; if a private key is found, the related transaction will be signed locally in the browser and submitted via a private mining pool to avoid exposing the private key in the public memory pool. https://(wublock123.com)/news/krackpot-webgpu-browser-bruteforce-bitcoin-puzzle-71-private-key-66816
