Just for fun, because it's hard to appreciate how strong a 256bit ECDSA key is. Base Numbers: - 2*128 guesses on average - public state of the art for ECDSA on an FPGA is 1315tps [0] - retail price of said fpga $10,000 [1] - total net income for xilinx from advanced FPGAs FY2022 (936M * 0.74 + 879M * 0.72) = 1325M [2] Ballpark numbers, we'll assume that attacker can buy 10x every FPGA xilinx made in 2022 for a 50% discount and can run them non stop for zero cost. We'll also assume they have a bunch of secret math geniuses and have a faster ECDSA implementation that can do 1,000,000,000 tps…
