Bitcoin and Lightning Community undertaking developer, John Cantrell, defined how he was in a position to efficiently hack a BTC deal with by checking round a trillion seed combos over the course of 30 hours. The feat was achieved as a part of a contest launched on Twitter by Alistair Milne — the CIO of the Atlanta Digital Foreign money Fund.
Milne printed hints to a 12-word Bitcoin pockets seed over the course of a number of days. Cantrell succeeded in brute forcing the mnemonic with solely eight out of the 12 phrases, finally claiming the 1 BTC prize contained inside.
Developer rented a number of graphics playing cards
Cantrell determined to lease a number of graphics playing cards via GPU marketplaces and Microsoft’s Azure cloud computing service after realizing that his Macbook may solely verify 1,250 mnemonic combos per second utilizing his self-written CPU seed solver.
The developer defined:
“I was worried about other people doing the same and is why I included a .01 BTC miner fee. I didn’t think even this would be enough and thought there could be a ‘race to zero’ where people continually increased the fee trying to get the miners to include their transaction in the next block.”
