Mining pool · FACT blockchain

Mining that is actually useful.

The Factory coordinates the CPUs of many participants to factor large integers — proof of useful work with real application in cryptography, computational number theory, and security auditing.

On factorization pools

§1
The mechanism.

A pool of primes, not hashes

An integer factorization pool works similarly to a cryptocurrency mining pool — but instead of hashing for blocks, it decomposes large composite numbers into their prime factors. The pool divides each factorization into subtasks, distributes them to contributors, and aggregates the results.

The methods.

Standing on serious algorithms

Distribution makes integers tractable that no single machine could factor, using:

  • General Number Field Sieve (GNFS)
  • Elliptic Curve Method (ECM)
The stakes.

RSA is a factoring problem

The security of RSA rests on the difficulty of factoring large semiprimes. A capable pool tests cryptographic strength of key sizes, supports academic research, identifies vulnerable keys in outdated systems, and benchmarks hardware on mathematically demanding workloads.

The community.

Research in the open

Researchers, students, and security professionals cooperate on hard factorization problems — cryptanalysis and auditing, hands-on education in computational number theory, and proof-of-concept demonstrations of factoring progress.

Payout frequency

Payout calculations run multiple times per week; actual timing varies with network speed. 101 block confirmations required.

Minimum payout

There is no minimum payout. You earn what you mined.

Pay per share

Every relation your worker submits is accounted.
