Bitcoin and Lightning Network project developer John Cantrell successfully hacked his BTC address by checking a trillion seed combination for 30 hours. This happened as part of a competition launched on Twitter by Alistair Milne, Atlanta Digital Monetary Fund CIO.

For several days, Milne published clues about a 12-word Bitcoin wallet seed. Using the Cantrell brute force method (trying all possibilities individually), he only got 8 out of 12 words and received 1 BTC award in the wallet.

The developer has rented several graphics cards
Cantrell determined that he can control 1,250 combinations per second using the CPU seed decoder he wrote himself on Macbook. To do this, he decided to rent several graphics cards through GPU markets and Microsoft's Azure cloud computing service.
