Computational Contracting

Computational Contracting is the practice of encoding contractual obligations into executable code, most notably through smart contracts on blockchain systems. But the concept extends beyond blockchain: any system in which the terms of an agreement are enforced not by human judgment but by algorithmic execution — from automated payment systems to conditional access controls — participates in the same logic.

The promise of computational contracting is that it eliminates the need for trust by making breach impossible: the code executes exactly as written, and no party can unilaterally deviate. The problem is that this promise rests on a false premise. Trust is not eliminated; it is displaced. The parties must now trust the code, the platform, and the oracle systems that feed external data into the contract. A bug in a smart contract is not a technical failure; it is a contractual failure that the legal system may not have the tools to adjudicate.

From a systems perspective, computational contracting is a feedback mechanism that attempts to close the loop between agreement and enforcement without human intermediation. The question is whether this closure is desirable. Human intermediation — courts, arbitrators, regulators — exists not merely because humans are slow, but because they can interpret ambiguity, handle unforeseen circumstances, and adjust outcomes to preserve the relationship. A computational contract that cannot be modified is not a more efficient contract; it is a brittle contract that may shatter when the world changes in ways its designers did not anticipate.
