When discussing blockchain security, everyone is used to focusing on consensus mechanisms—validators, signatures, finality. But what are we missing? Storage.

Storage is often treated as a supporting role, as if security equals cryptography. In reality, once data access becomes problematic, this logic collapses. When some people can freely access data while others cannot see anything, the trust built by technology is compromised from the back door. That is the real risk point.

Causing network security to collapse doesn't require hackers to intrude or system vulnerabilities to be exploited. As long as ordinary participants find it increasingly difficult to query historical data, the security posture of the network is already deteriorating.

As on-chain data accumulates, nodes capable of storing all data will become increasingly scarce. The final outcome is nothing more than everyone relying on a few large operators to provide data services. On the surface, the validation process seems fine, cryptographic verification proceeds as usual, but all of this is based on the assumption that "you trust these nodes to cooperate honestly." Security? It has long been nominal only.

This is why storage incentive mechanisms cannot be optional. Incorporate storage and incentives into the security model, making data accessibility a core part of system design—that is the way to prevent centralization of power. It’s not always necessary for someone to agree, but in practice, it does play a role.

When data cannot be accessed, even the strongest cryptographic defenses cannot hold.
