Marschain is an independent public blockchain based on Proof-of-Contribution (PoC) consensus, integrating the Christmas Equation, Oracle Equation, and decentralized mining pools. With "burning equals computing power" as its core rule, it constructs a value loop through rigid deflationary mechanisms in both-party programs, creating a self-consistent decentralized public blockchain for emerging digital currencies. MarsChain's three core mechanisms are the Proof-of-Concept (PoC) mechanism, the Christmas Equation, and the Oracle Equation (periodic expansion and deflationary regulation of computing power), along with a unique personal mining pool mechanism. These three mechanisms work in a closed loop to jointly drive deflation, computing power multiplication, and network expansion, forming a long-term positive cycle.
