This is just an area where you can learn about blockchains and Cardano. Yes, there are lots of places on the internet you can do that, but I find a lot of it complicated and hard to navigate. Here, I keep it simple. I am trying to bust the jargon.
The concept of Bitcoin was invented by Satoshi Nakamoto. In his vision the function of the system was to create an immutable database which can be trusted to hold money. This is a great achievement, and there are many pitfalls. The features of the system were kept as simple as possible in order to reduce the attack vectors, so the only peice of information stored in the transactions was the OP_RETURN value. Bitcoin is complicated enough, so most programmers in the Bitcoin world stuck to this path, making changes to improve only slowly and carefully. However, a small group of programmers including Charles and Vitalik realised that by relaxing the limit of the size of the OP_RETURN it would be possible to store enough information to include rules about the transactions. In fact a whole computer program with arbitrarily many rules could be included.
Bitcoin can't be changed like that, it relies on the perception of safety to remain valuable. However a new coin was created called Ethereum with its own blockchain. This included the idea now known as Smart Contracts into the rule base. A language called Solidity was invented whoch could be used to define the rules of a transaction.
