        @zooko Given BLAKE2 or SHA-3 running on 512 bits mode, faster hash will be break more easily than slower one. So BLAKE2 is the weakest…

      @zooko On each case, you have to try at worst 2^512 times to collid, but the faster take less time to perform the full search.

    @zooko Not considering known weakness, from 2 same output size hash function, the most secure is the slowest one.

      @zooko And for internal checksum, there are better integrity check available, because safety is not the purpose, error detection is.

        @zooko And for just error detection, you don’t care about 512 bits output, CRC32 is much faster. Or hamming matrix for error correction.
