🪨 Dacite

Data citing with fused hashing.

Dacite is a system for distributed immutable data structures with content-addressed nodes.

Features

• Structural sharing — unchanged data shares identity across versions
• Efficient sync — fetch only what changed
• Lazy access — pull only what you use
• Perfect caching — immutable = cacheable forever

Status

🚧 Early design phase — spec in progress, reference implementation underway.

Use Cases

• Configuration management — server pushes root hash, clients pull what they need
• Distributed state — sync structured data across nodes efficiently
• Versioned data — every root hash is a complete snapshot
