Can side channels (like gossip) be used to confirm slash event authenticity?
Side channels, particularly peer-to-peer gossip networks, are already a primary method for detecting slashable offenses but are poor for confirming authenticity in a trustless way. Nodes gossip observed violations to ensure the network becomes aware of malicious actors. However, using gossip to confirm if a slash is an FP is problematic. It relies on off-chain, non-verifiable information ("my logs show a bug") and could devolve into a "he-said-she-said" scenario vulnerable to social manipulation. While a grassroots warning spreading through gossip that "Client v2.1 has a double-sign bug, hold off on slashing" can be a useful emergency brake, it cannot be the final arbiter. The ultimate confirmation of authenticity must be based on verifiable on-chain data and a formalized dispute process, not social consensus.
