# fuel-core vs linera-protocol

fuel-core and linera-protocol share 11 technologies: tower, axum, rocksdb, lru, quick_cache, Tokio, wasmtime, indicatif, ed25519-dalek, tracing, and tracing-subscriber. Both are written in Rust.

- [FuelLabs/fuel-core](https://seerepo.com/r/FuelLabs/fuel-core): Rust full node implementation of the Fuel v2 protocol.
- [linera-io/linera-protocol](https://seerepo.com/r/linera-io/linera-protocol): Main repository for the Linera protocol

## What they share and what sets them apart

- In common: tower, axum, rocksdb, lru, quick_cache, Tokio, wasmtime, indicatif, ed25519-dalek, tracing, tracing-subscriber
- Only in fuel-core: aws-sdk-s3, Redis, AWS S3, crossterm, termion, parquet, prometheus-client, tracing-appender, tracing-core
