Blockchain has traditionally been discussed as the technology behind cryptocurrencies. In recent years, however, its role has been re-evaluated as social infrastructure.
The shift is driven by a national-level question: who should be trusted in digital transactions and records, and how should that trust be built?
Trust That Can Be Verified
Financial transactions, administrative procedures, and cross-border exchanges of contracts and documents have traditionally relied on a specific administrator or centralized system.
As risks such as system failures, fraud, and dependence on foreign infrastructure become more visible, societies need to reconsider the foundation of trust itself.
Blockchain provides transparency through verifiability. Records can be checked later by external third parties. Instead of someone deciding that something is correct, others can confirm whether it is correct.
A Global Infrastructure Conversation
The United States is exploring distributed ledger technology in securities settlement. The European Union has developed the European Blockchain Services Infrastructure for cross-border use cases. China has positioned blockchain as a national strategic technology.
Japan is part of the same conversation. Blockchain is no longer only a web3 trend; it is being discussed as a possible next-generation standard for critical infrastructure.
