How can one understand etherium, smart contracts?

Question

bitcoin

Can you give more or less simple examples of how ethereum can be used along with the blockchain. Wherever you read, for the most part, they write in a generalized way, such as, with the help of this, it will be possible to replace jur. firms, build new currencies, etc.
What simple things can be written on etherium? How do smart contracts interact?
For example, I wrote smart contracts. What to do next with it?
Thank you very much, because I'm just delving into this topic. I would appreciate any clarifying help.

Answer 2

smart contract - a contract, remember the contract of sale ...
Ideally, a smart contract turns into a smart contract enterprise ...
You want to sell a car - I buy, everyone enters the network with this chain (blockchain),
The history of either the buyer's wallet, or the seller of the car is checked, even before the smart contract works... Having received the keys and documents for the car, I digitally sign
and the car is mine, but you also sign that you received the money...
After 5 minutes, as I drove the purchased car, a traffic cop stops me
and, punching the characteristics of the car through the database, sees that it is mine!!
