Blockstream has launched Simplicity, a new smart contract language for Bitcoin’s layer-2 protocol Liquid, aiming to make Bitcoin programmable for decentralized finance. SimplicityHL, a higher-level implementation, is also introduced for easier development. This language differs from Ethereum’s Solidity due to the unique architectures of the two blockchains.

Simplicity utilizes Bitcoin’s UTXO architecture, in contrast to Ethereum’s network-wide state. This difference impacts how smart contracts function, with each contract needing to include all necessary information within transactions. Solidity developers will need to adjust to this new approach, which aims to create safer and more contained contracts by design, without recursion or unbounded loops.

The rise of domain-specific smart contract programming languages continues with Simplicity joining the list. Noir, Leo, and Ethereum’s Vyper are examples of languages tailored for specific purposes like privacy-preserving applications and reducing attack surfaces. These languages offer different features and syntax to cater to the evolving needs of smart contract development.
