Recap | Transition to Web3 - Course 3 | How Smart Contracts Work

🎉 Congratulations—we have the building blocks of a decentralized computing system!

Let’s go over what we’ve done so far:

We wrote a code (“smart contract”) and put it into a block.
All nodes have a copy of this code since they have a copy of all blocks. This made our code “decentralized.”
If a user wanted to trigger our code, they had to let all nodes know. This trigger was also included in blocks!
The nodes have their own virtual computer that allowed them to run the code before the trigger is mined and added to the blocks.
When the code was run, we had several outcomes like new transactions and states. These were also added in new blocks.

✍️ Summary: The code itself, its execution transaction, and all the results of the execution are now in a blockchain. Mind-blowing, right?
