Consensus Security: Validation Bugs, Supply & Recovery

Consensus security concerns whether independent blockchain nodes enforce the same monetary and transaction rules, reject malformed blocks and prevent unauthorized issuance. ryo.news studies vulnerabilities in block validation, inherited or newly introduced protocol code, incomplete test coverage, protocol upgrades, emergency restarts and independent auditing. Case studies include Pirate Chain's 2026 coin-import and script-check failures, Zano's Gateway Address exploit, Ravencoin's mining-verification failure and lessons for Ryo's Halo 2 testing. This archive distinguishes cryptographic proof validity from the surrounding consensus implementation and from the economic recovery of users.
