Repository Structure

The main crates and directories of this repository can be summarized as follows: (listed from low to high levels in the dependency graph)

• linera-base Base definitions, including cryptography.

• linera-version A library to manage version info in binaries and services.

• linera-views A library mapping complex data structures onto a key-value store. The corresponding procedural macros are implemented in linera-views-derive.

• linera-execution Persistent data and the corresponding logic for runtime and execution of Linera applications.

• linera-chain Persistent data and the corresponding logic for chains of blocks, certificates, and cross-chain messaging.

• linera-storage Defines the storage abstractions for the protocol on top of linera-chain.

• linera-core The core Linera protocol, including client and server logic, node synchronization, etc.

• linera-rpc Defines the data-type for RPC messages (currently all client ↔ proxy ↔ chain ↔ chain interactions), and track the corresponding data schemas.

• linera-client Library for writing Linera clients. Used for the command-line client and the node service in linera-service, as well as the Web client in linera-web.

• linera-service Executable for clients (aka CLI wallets), proxy (aka validator frontend) and servers.

• linera-sdk The library to develop Linera applications written in Rust for the Wasm virtual machine. The corresponding procedural macros are implemented in linera-sdk-derive.

• examples Examples of Linera applications written in Rust.

Prerequisites

See INSTALL.md for software requirements to develop in this repo.

Quickstart with the Linera CLI tool

The following commands set up a local test network and run some transfers between the microchains owned by a single wallet.

…

Enable logs for user applications:

export LINERA_APPLICATION_LOGS=true

Set the path of the future wallet:

…

More complex examples may be found in our developer manual as well as the example applications in this repository.
