OT systems are becoming high-value targets, fast.
Power grids, manufacturing, transportation...none were built for modern cyber warfare.
From a #BlockchainSecurity lens, this isn’t just a threat, it’s a signal.
OT still runs on trust-by-default, static configs, and legacy assumptions. Attackers exploit all of it.
#Blockchain introduces what OT has lacked: verifiable trust.
Key Kealities:
• Downtime = leverage for nation-states + ransomware
• IT → OT lateral movement dominates
• Weak identity + unmonitored endpoints = core gaps
• IR is harder when uptime = safety
Where blockchain helps:
• Immutable logs for config + event integrity
• Decentralized ID for machines + operators
• Zero Trust via cryptographic proof
• Firmware/controller transparency
• Cross-network validation to cut blind spots
Cyber-physical systems can’t rely on assumptions.
#CryptographicTrust = Resilience.
