It's probably possible to take just the first (or last) 128 bits 
of BLAKE3 and the result might have better properties than MD5 
(considering that MD5 is broken). There are some answers related 
to "truncated hash" on the Internet about SHA-256, but any 
cryptographically secure hash is likely to be similar in this 
aspect:
