Smart contracts are like digital agreements that run on blockchain technology. Once they're set up and running, they can't be changed. This "no-change" rule is to ensure security and trust in transactions without needing middlemen.

But what if there's a mistake or something needs updating? In those cases, developers create a new version of the smart contract with the fixes or changes needed. They then move any important info or assets from the old contract to the new one. This process can be tricky because it has to be done carefully to keep everything running smoothly.

Some blockchain platforms, like Ethereum, have found ways to make changes easier without breaking the "no-change" rule. They use things like upgradable smart contracts or proxy contracts. These methods let certain parts of the contract be updated while keeping its history intact. It's like giving a little wiggle room for updates while still keeping everything secure and unchangeable at its core.

Basically, smart contracts are supposed to stay the same once they're set up, but some new techniques make them a bit more flexible. These methods, like upgradable smart contracts and proxy contracts, give a way to adjust things without breaking the rule of no changes.
