Arvind Narayanan closed out Princeton's online course on Bitcoin and Cryptocurrency Technologies with an unexpected comparison. The computer science professor drew a parallel between governments and blockchain technology, arguing they represent two different answers to the same problem.
Narayanan does not align with cryptoanarchy, but he recognized something in the mechanics of blockchains that mirrors what states accomplish. "The state is one way to scale society past small groups where everyone trusts each other," he explained in his final lecture. "The curious thing about that is that it's very similar to the benefits that are touted for the cryptographic way of doing things in that these transactions are over the Internet where you don't necessarily trust the other person."
This comparison suggests how bitcoin might disrupt institutional power. If blockchains solve the trust problem that governments solve, could they compete with state authority?
Both governments and blockchains operate as consensus mechanisms. Bitcoin's network reaches agreement on the ledger's state. Democratic governments, in theory, build consensus through voting. Narayanan framed it this way: "The state and crypto really are delivering a very similar benefit at the end of the day, even though through very different mechanisms."
Some bitcoin advocates proposed using blockchains to bypass elected representatives. Blockchains do not solve every consensus problem, though.
Narayanan rejected the notion that blockchains could replace governments outright. He argued that cryptographic solutions only succeed when they integrate with existing state infrastructure. Without interoperability with governments, he said, innovation stalls. "Unless you have some way of interoperating with the state, you've not made any progress."
Smart property illustrates his point. Someone transfers a car title to you via blockchain, but the state-issued certificate remains in the seller's name. From the government's legal perspective, no transfer occurred. The original owner could claim the vehicle was stolen while retaining the official title. This gap closes only if governments themselves adopt blockchain-based property registration.
Cryptoanarchists reach a different conclusion. Their vision abandons the state and replaces it with encrypted networks and decentralized systems. The cypherpunk movement spent years developing cryptographic cash for this purpose. Satoshi Nakamoto, who created bitcoin, may reject Narayanan's framework.
Users have deployed blockchains against state authority in some ways. Darknet marketplaces demonstrate this capacity. As developers push further, cypherpunks will build more systems designed to sidestep government oversight. For those who hold this vision, coexistence with the state was never the goal.
