Thanks to Cointelegraph for the feature. Their article framing: "Formal verification is the difficult answer." Long road yes, but AI development is exponential. Let me describe the smart contract model of the future.
1. A contract is defined by a spec, not code. For a DEX, a short set of invariants: value preservation, no unauthorized withdrawals, slippage bounds. The spec goes in first.
2. Code gets uploaded next, verified against the spec on-chain in a dedicated factory, with full proofs. If it satisfies the invariants, it compiles and deploys into the contract. The code can be in any language, or even machine code - doesn't matter.
3. Upgrades are allowed, but only if new code still satisfies the original spec. The contract evolves without breaking its own rules.
4. NEAR is built for this. WASM runtime gives deterministic execution on a formally specified VM - verification can happen at the bytecode level regardless of source language. Native account namespacing lets us reserve *.verified as a protected top-level for spec-compliant contracts. A factory deploys into that namespace only after on-chain proof verification. Users see at a glance what tier they're interacting with.
Formal verification, quick primer: instead of testing code against examples (which can miss edge cases), you mathematically prove that the code satisfies a set of properties for ALL possible inputs. If the proof succeeds, the code is guaranteed correct with respect to those properties. No hidden bugs, no missed cases.
We can't pay developers 300M to find the vulnerabilities that hackers are already earning 300M exploiting. But we can architect toward a world where hacks become structurally impossible. Formal verification is the path.
