COWBOYCION (COWBOY for short in Chinese) is a novel cryptocurrency based on Multilayer Conditioned Proof of Capacity (MCPOC). Its full name is Proof of Credit in the Development of Digital Ecology in the World. It is committed to establishing a comprehensive digital ecosystem that is free, open, technologically innovative, and environmentally expanding. Its main features include using hard drives as consensus participants, reducing the cryptocurrencys reliance on electricity. Additionally, it innovatively adopts hierarchical capacity conditioned proof and dynamic capacity proof, pioneering an automatic quantitative sealing and destruction mechanism to provide multi-level rights protection for participants. Furthermore, it upgrades and optimizes the circulation mode, lowers the participation threshold, and makes the production model more decentralized and less reliant on large players. This makes COWBOY safer and more reliable, enabling everyone to participate in cryptocurrency mining, generating credit and value through mathematical algorithms and distributed mining.
