FACT0RN uses integer factorization as its PoW instead of hashing. The RSA cryptographic system has been widely used to secure data online by relying on the difficulty of factoring integers. Banks today use it to secure their data. No other blockchain has been able to use factoring  in the blockchain space.



Integer factorization is a mathematical process that involves breaking down a given integer into its prime factors, which are the fundamental building blocks of whole numbers. 

This process plays a crucial role in number theory and has significant importance in areas like cryptography, number theory, abstract algebra, elliptic curves, Galois Theory, and lattice based cryptography.
