Krackpot Launches Lottery to Win 6 BTC with a GPU

Krackpot, a lottery developed by Simon Males, allows users to try to win 6 BTC, which is approximately 335,000 euros, by utilizing the power of their GPU. The application runs directly in the browser and aims to solve Bitcoin Puzzle 71, which involves finding a private key in a space of 2 to the power of 70, or about 1.18 sextillion possibilities. No downloads or registrations are required; users simply need to open the site and click on Start for the machine to test billions of private keys. A RTX 4070 graphics card can test around 44 million keys per second, but it would take approximately 430,000 years to scan the entire space. A RTX 3070 would require 830,000 years, and a MacBook Air M1 would take over 3 million years. However, if a million GPUs were working in parallel, the median time to win would drop to about one year. If a user finds the key, the recovery transaction is signed locally to prevent the theft of funds. Krackpot is part of a trend where Bitcoin cryptography is being put to the test, with similar initiatives assessing the resilience of cryptographic algorithms.
