Clarity Language for Smart Contracts

Clarity Language
Clarity is a new language that brings smart contracts to Bitcoin. It
is a decidable language, meaning you can know, with certainty, from
the code itself what the program will do. Clarity is interpreted (not
compiled) & the source code is published on the blockchain. Clarity
gives developers a safe way to build complex smart contracts. The
Clarity open-source project is supported by the Stacks ecosystem,
Hiro PBC, & Algorand.

Why Clarity?
Predictable
The Clarity language uses precise and unambiguous syntax that allows
developers to predict exactly how their contracts will be executed.
Secure
The Clarity language allows users to supply their own conditions for
transactions that ensure that a contract may never unexpectedly
transfer a token owned by a user.
No compiler
Contracts written in Clarity are broadcasted on the blockchain
exactly as they are written by developers. This ensures that the code
developers wrote, analyzed, and tested, is exactly what gets
executed.

The future of Smart Contracts
Clarity recognizes the need for smart contract languages that are
more safe, secure, and predictable. Our goal is to help the smart
contract industry mature beyond its current state. Clarity is
designed by scientists from Princeton and MIT, and the open-source
project is initially supported by Blockstack and Algorand. We welcome
other projects and developers to join this effort and help
contribute!
