Grin is a minimal, open-source implementation of the Mimblewimble blockchain protocol, providing a privacy-preserving digital currency with no addresses or visible amounts. It is written in Rust and features Cuckoo Cycle proof of work, transaction aggregation, and prunable chain state for scalability.

Use cases

• run a privacy-preserving cryptocurrency node
• send and receive digital cash without addresses or visible amounts
• mine a cryptocurrency with Cuckoo Cycle proof of work
• study a minimal Mimblewimble blockchain implementation
• build applications on top of a scalable, prunable blockchain

When to choose

• you need default-on transaction privacy and fungibility
• you want a lightweight blockchain whose state scales with users rather than transaction history
• you prefer a fair launch with no ICO, pre-mine, or dev tax
• you want a clean, auditable Rust codebase for blockchain research

When to avoid

• you need smart contracts or programmable assets
• you want a widely adopted currency with deep exchange and merchant support
• you need fast finality or sub-minute confirmation guarantees
• you prefer ASIC-friendly or established proof-of-work ecosystems
