Exonum is an extensible open-source Rust framework for building private, permissioned blockchain applications with a custom Byzantine fault-tolerant consensus algorithm. It provides modular crates for the core ledger, node implementation, cryptography, merkelized storage, HTTP APIs, and SDKs for writing services in Rust and Java.

Use cases

• build a private permissioned blockchain for asset management
• create a tamper-proof land registry or e-auction ledger
• implement a supply chain tracking blockchain
• write smart contract services in Rust or Java on a distributed ledger
• anchor a private blockchain's state to the Bitcoin blockchain
• build a cryptocurrency application with cryptographic proofs
• run a high-throughput ledger with fast transaction finality

When to avoid

• you need a public, permissionless blockchain with open validator participation
• you want a general-purpose smart contract platform with a large ecosystem like Ethereum
• your team is not comfortable with Rust or Java service development
• you need a turnkey product rather than a framework requiring custom development
