The Decentralization Defense Fund (DDF) is dedicated to preserving Bitcoin's core identity as a decentralized, permissionless, and censorship-resistant money and payment system. In a landscape where pressures to transform Bitcoin into a multifunctional platform threaten its foundational principles, the DDF stands firm in prioritizing node decentralization and the integrity of Bitcoin's codebase. Our mission is to ensure that Bitcoin remains true to its original intent as outlined by Satoshi Nakamoto: a peer-to-peer electronic cash system, not a database or platform for speculative crypto projects. By focusing on node runners and code security, we safeguard Bitcoin’s ability to function as sound money for generations.
