comment Safety when disclosing hashes of secrets used to calculate other secrets
@IlmariKaronen At the moment I can't disclose what is the practical application of this, but the technical side of it is generating hashes of a secret number and a given number that are unknown before the operation takes place despite the hash of the secret number being known.

comment Safety when disclosing hashes of secrets used to calculate other secrets
@IlmariKaronen To prevent anyone from knowing a result of a hash for particular input before they query the system. In other words, as long as the secret is not known, the result of SHA256(A+B) for non-empty B should be unknowable before someone sends a query with B to the system.

comment Proof of work for determining whether a number is prime?
@CodesInChaos At the current moment there are people that are doing what I intend to automate by feeding the potential numbers to be proven as non-primes more or less "by hand" to a program that performs the checks. So I know this sort of automation would be useful and the work is not pointless (people are doing this for research). My project is not to figure out how to effectively find prime divisors (which is done by more math-savvy people), but to automate the process of work distribution and rewarding for a completed task (even if fruitless).

comment Proof of work for determining whether a number is prime?
@CodesInChaos I am checking whether a number is prime for numbers that are not yet known to be prime for mathematicians. I must've not worded it clearly. The numbers that will be checked for being prime are very big, but to distribute the work every user would be checking a range of possible divisors to that number. I need to have a proof of work for when a divisor is not found in a given range the user is checking in.

comment Proof of work for determining whether a number is prime?
@Thomas It is a distributed proof of work scheme. I am thinking about distributing people checking whether a really big number has divisors in specified range.
