Title: Implementing OP_MUL with OP_ADD Post by: RobinLinus on February 06, 2020, 10:58:56 AM For fun I implemented OP_MUL using OP_ADD. You can find the code here on Github. (https://github.com/coins/bitcoin-scripts/blob/master/op_mul.md)
Feedback very appreciated! And I have a question: do you guys know any good source for advanced bitcoin scripts? Is there something like a library for scripts?
