## What are smart contracts?
Smart contracts are automated digital agreements that are programmed. They are self-executing, incorruptible, and unalterable. They do not require any actions or the presence of third parties.
Smart contracts are pre-programmed, automatic digital agreements. They are self-executing, unalterable, and incorruptible. They don't necessitate any acts or the presence of others.

## Two worlds of smart contracts
We can break smart contracts and financial transactions down into two worlds:

In one world, you want to send some notion of value between one actor (or group of actors) to another actor (or a group of actors). There has to be a representation of that value, the terms and conditions behind it, and an event to trigger it. This is what we call a financial contract and best implemented with a domain-specific language. This world has nothing to do with replacing a big company or this common notion that we might have with dapps.
In one world, you wish to communicate a sense of worth from one actor (or group of actors) to another (or a group of actors). There must be a representation of that value, as well as the rules and circumstances that govern it, as well as a trigger event. A financial contract is what we call it, and it's best done with a domain-specific language. This world has nothing to do with replacing a big company or this common notion that we might have with dapps.

In the other world, you want to write programs, maybe even replace a large company, perhaps solve something smaller. Those applications consist of a triangle:
In another world, you'd like to build programs, possibly even replace a major corporation, or address a smaller problem. A triangle is formed by these applications:

- The client - this is what runs on your computer.
- The server - this is what runs on someone's server (or multiple servers).
- The smart contract - the piece of the code that actually runs decentralized.
- The client is the portion of the program that runs on your computer.
- A server is a computer that operates on someone else's computer (or multiple servers).
- The smart contract is a piece of code that allows a decentralized system to operate.

## Programming languages
- [Marlowe](marlowe) - a domain-specific language, it covers the world of financial contracts.
