Factor

FACTOR is a decentralized infrastructure protocol that rewards real mathematical problem solving through Useful Proof of Work (uPoW). It transforms cryptographic mining into an open marketplace for integer factorization, accessible to researchers, miners, developers, and institutions that want to advance applied mathematics and computational cryptography. Unlike traditional Proof of Work networks such as Bitcoin, where energy is spent on arbitrary hashing to secure the chain, FACTOR redirects that same computational effort toward solving meaningful mathematical challenges. Every cycle of computation contributes to the factorization of large composite numbers, the foundation of modern encryption systems. This approach preserves the security and fairness of decentralized mining while channeling it into a task with direct academic, industrial, and cryptographic value. At its core, FACTOR merges blockchain incentives with scientific utility. The protocol introduces an on-chain bounty marketplace, allowing anyone to post mathematical or cryptographic challenges and reward the community for solving them. Researchers can outsource difficult factorizations.
