On 18 September, an e-gate outage disrupted Sydney and other Australian international airports, forcing manual passenger processing. Service was restored by 11am; the cause remained under investigation. "Report" (https://www.news.com.au/travel/travel-updates/incidents/sydney-airport-hit-with-system-outage/news-story/8e9227909db6fed27b515c16b2c243c0)
That should provoke a serious question: how much of our freedom depends on a service desk somewhere remaining online?
A properly decentralised blockchain is designed so that losing one operator does not mean losing the shared record. Independent nodes retain and verify it. Bitcoin’s architecture makes verification possible without relying on a single central intermediary. "Bitcoin whitepaper" (https://bitcoin.org/bitcoin.pdf)
But precision matters. Blockchains can fail. A working ledger cannot repair a broken airport network, biometric scanner or gate. We do not yet know whether a blockchain would have prevented this incident. Conventional distributed infrastructure can also provide resilience.
The principle worth demanding is this: one service failing should not make everyone’s credentials unverifiable. Passport details should remain private, with cryptographic verification and carefully designed fallback procedures.
Then comes the political tension.
“Fiat governments will never adopt blockchain” is too absolute. Central banks are already pursuing it. The ECB’s stated ambition includes preserving central bank money’s role in a tokenised financial system. "Reuters" (https://www.reuters.com/business/finance/ecb-should-embrace-blockchain-safeguard-its-role-schnabel-says-2026-08-28/)
My argument is that governments will readily adopt the machinery while resisting the surrender of unilateral control.
A ledger they administer fits existing power structures. A monetary network whose rules they cannot unilaterally rewrite presents a different proposition.
The same independence that protects a system from an operator’s failure also limits that operator’s authority.
Adopting blockchain is easy compared with accepting that you are no longer its final authority.
