## Background
|
|
|
|
Solidity is a statically-typed curly-braces programming language designed for developing smart contracts
|
|
that run on the Ethereum Virtual Machine. Smart contracts are programs that are executed inside a peer-to-peer
|
|
network where nobody has special authority over the execution and thus they allow to implement tokens of value,
|
|
ownership, voting and other kinds of logics.
|
|
|
|
## Build and Install
|
|
|
|
Instructions about how to build and install the Solidity compiler can be found in the [Solidity documentation](https://solidity.readthedocs.io/en/latest/installing-solidity.html#building-from-source)
|
|
|
|
|
|
## Example
|
|
|
|
A "Hello World" program in Solidity is of even less use than in other languages, but still:
|
|
|
|
```
|
|
pragma solidity ^0.4.16;
|
|
|
|
contract HelloWorld {
|
|
function helloWorld() external pure returns (string memory) {
|
|
return "Hello, World!";
|
|
}
|
|
}
|
|
```
|
|
|
|
To get started with Solidity, you can use [Remix](https://remix.ethereum.org/), which is an
|
|
browser-based IDE. Here are some example contracts:
|
|
|
|
1. [Voting](https://solidity.readthedocs.io/en/v0.4.24/solidity-by-example.html#voting)
|
|
2. [Blind Auction](https://solidity.readthedocs.io/en/v0.4.24/solidity-by-example.html#blind-auction)
|
|
3. [Safe remote purchase](https://solidity.readthedocs.io/en/v0.4.24/solidity-by-example.html#safe-remote-purchase)
|
|
4. [Micropayment Channel](https://solidity.readthedocs.io/en/v0.4.24/solidity-by-example.html#micropayment-channel)
|
|
|
|
## Documentation
|
|
|
|
