Hi , I am a newbie in bitcoin learning. I am just learning the source of bitcoin. Now my aim is to change the hash algorithm in order to learn the knowledge.The version is bitcoin-0.20. I want to change the hash to x13, so I add the x13 files in ~/src/crypto/x13hash$ ls
aes_helper.c bmw.c echo.c groestl.c hamsi_helper.c keccak.c shavite.c skein.c sph_blake.h sph_cubehash.h sph_fugue.h sph_hamsi.h sph_keccak.h sph_shavite.h sph_skein.h sph_types.h
blake.c cubehash.c fugue.c hamsi.c jh.c luffa.c simd.c sm3.c sph_bmw.h sph_echo.h sph_groestl.h sph_jh.h sph_luffa.h sph_simd.h sph_sm3.h
