  "account": "GhostKey Protocol is a decentralized, peer-to-peer authentication system that eliminates the need for central password stores, OAuth relays, and SMS OTP vectors. By anchoring to hardware security modules (WebAuthn/FIDO2), it creates a secure authentication substrate. The protocol's core pillars include an autonomous core with cryptographic challenge verification, a P2P node daemon that facilitates verification events through socket-based mesh networking, zero-knowledge commitments to protect user identity, and a tamper-proof ledger using SHA-256 hash-chained verification blocks. To quickly set up a local sovereign node, users can clone the repository, run the autonomous node using a CLI, perform peer hardware handshakes, and audit the local ledger integrity. The project is available on GitHub with a v2.0 release and technical whitepaper, inviting peer review from backend engineers, systems developers, and cryptographers to improve mesh block synchronization and ZKP commitment entropy.",
  "summary": "Traditional authentication architectures rely on central password stores, OAuth relays, and costly SMS OTP vectors. These create central honeypots vulnerable to credential stuffing, database leaks, and account sharing. GhostKey Protocol is an autonomous, decentralized authentication substrate anchored to physical device Hardware Security Modules (WebAuthn / FIDO2). 🏛️ Core Architecture Pillars…",
