I was looking into this code base (https://github.com/vstoykovbg/doubleslow) and the following phrase caught my attention:
DANGER of catastrophic data loss! One bit flip (due to cosmic rays for example) can make the result of the hash functions completely different. Run the scripts several times to confirm that they produce the same output given the same input. Read how these scripts work and why the risk of bit flip is high (hint: RAM usage).
Should we be hashing inputs more than one time to avoid this kind of issue?
