Basic Escrow — Simplicity Code
Funds are released to a recipient only if both parties sign.
contract escrow {
input: sig senderSig, sig recipientSig
output: funds released if verify(senderSig) && verify(recipientSig)
}Simplicity Language Guide
Simplicity is a typed, functional smart contract language designed for blockchain applications, with a focus on formal verification, expressiveness, and secure, predictable execution, primarily targeting Bitcoin and similar blockchain platforms.
Primary Use Cases
- ▸Formal-verifiable smart contracts
- ▸Multi-signature wallets
- ▸UTXO-based DeFi primitives
- ▸Escrow and payment channels
- ▸High-assurance blockchain applications
Notable Features
- ▸Strong static typing prevents many runtime errors
- ▸Composable functional expressions
- ▸Designed for formal verification
- ▸Low-level predictable execution
- ▸Deterministic and sandboxed semantics
Origin & Creator
Simplicity was developed by Russell O’Connor and contributors from Blockstream around 2015-2017 to improve upon Bitcoin Script, with a focus on safer, verifiable smart contracts.
Industrial Note
Simplicity is primarily used in UTXO blockchain systems for secure, high-assurance smart contracts, including multi-signature wallets, DeFi primitives on Bitcoin sidechains, and formally verified financial applications.
