A smart contract is neither a contract nor smart. It’s a marketing phrase awkwardly slapped onto it.
Let’s imagine something simple: if A deposits 20 $ETH before Friday, the code releases those funds to B. Nobody signs paperwork or calls a notary. The code checks the condition and acts on its own.
What if the condition isn’t met? The code doesn’t need anyone to decide: it simply doesn’t release the funds.
Under the hood, the code lives as copies on thousands of computers that agree on each block of data, linked together with a cryptographic signature that’s almost impossible to break. Each node runs the same copy, so the result is the same for everyone.
This is what they call a smart contract.
But here’s what almost nobody tells you: the code does what it says, not what the team meant. If there’s a bug, it still executes. And since it’s already been published on the network, nobody can go in and fix a line. Fixing it means publishing a new contract or migrating the entire network, and that’s neither quick nor free.
KEY CONCEPTS
- It isn’t a legal contract signed in front of lawyers. It’s code that runs on its own, without traditional legal recourse.
- It doesn’t need a person to check every step. By design, it executes without constant human supervision.
- A programming error doesn’t stop the code from running. It executes anyway, because it can’t distinguish intention from outcome.
- Many contracts rely on oracles to read external data. If the oracle fails, the contract fails—even if its code is perfect.
When people talk about a DeFi hack, this is almost always the cause: a line of code doing exactly what it said, not what someone imagined.
