Fuzzamoto is a fuzz testing tool for Bitcoin full nodes. For the last year, Niklas Gögge (dergoegge (npub1m78…7h66)) has been building Fuzzamoto with the goal of:
“an external testing suite that gets as close as possible to taking production binaries as input and producing bugs as output”
Part 1 of Brink’s blog series on Fuzzamoto provides an introduction of Fuzzamoto including its motivation, a design overview, and the first bugs found.
