|
Solidity is an object-oriented, high-level language for implementing smart
|
|
contracts. Smart contracts are programs which govern the behaviour of accounts
|
|
within the Ethereum state.
|
|
|
|
Solidity was influenced by C++, Python and JavaScript and is designed to target
|
|
the Ethereum Virtual Machine (EVM).
|
|
|
|
Solidity is statically typed, supports inheritance, libraries and complex
|
|
user-defined types among other features.
|
|
|
|
With Solidity you can create contracts for uses such as voting, crowdfunding, blind auctions,
|
|
and multi-signature wallets.
|
|
|
|
.. note::
|
|
The best way to try out Solidity right now is using
|
|
`Remix <https://remix.ethereum.org/>`_
|
|
(it can take a while to load, please be patient). Remix is a web browser
|
|
based IDE that allows you to write Solidity smart contracts, then deploy
|
|
and run the smart contracts.
|
|
|
|
.. warning::
|
|
Since software is written by humans, it can have bugs. Thus, also
|
|
smart contracts should be created following well-known best-practices in
|
|
software development. This includes code review, testing, audits and correctness proofs.
|
|
Also note that users are sometimes more confident in code than its authors.
|
|
Finally, blockchains have their own things to watch out for, so please take
|
|
a look at the section :ref:`security_considerations`.

Language Documentation
|
|
----------------------
|
|
|
|
On the next pages, we will first see a :ref:`simple smart contract <simple-smart-contract>` written
|
|
in Solidity followed by the basics about :ref:`blockchains <blockchain-basics>`
|
|
and the :ref:`Ethereum Virtual Machine <the-ethereum-virtual-machine>`.
|
|
|
|
The next section will explain several *features* of Solidity by giving
|
|
useful :ref:`example contracts <voting>`.
|
|
Remember that you can always try out the contracts
|
|
`in your browser <https://remix.ethereum.org>`_!
|
|
|
|
The fourth and most extensive section will cover all aspects of Solidity in depth.
|
|
|
|
If you still have questions, you can try searching or asking on the
|
|
`Ethereum Stackexchange <https://ethereum.stackexchange.com/>`_
|
|
site, or come to our `gitter channel <https://gitter.im/ethereum/solidity/>`_.
|
|
Ideas for improving Solidity or this documentation are always welcome!
