Shardeum is an innovative EVM-compliant blockchain platform that leverages dynamic state sharding to achieve unprecedented scalability. By implementing a sharding model, Shardeum ensures faster processing times and lower transaction costs without compromising security or decentralization.

• Scalability: Horizontal scalability through sharding
• High Performance: Low latency and high throughput
• Security: Advanced cryptographic techniques and robust consensus protocols
• Decentralization: Truly decentralized network with no single point of failure
• Interoperability: EVM compatibility for existing DApps and smart contracts

• First, setup your local dev environment for Shardeum
• Node.js (v18.16.1)
• npm (v9.5.1)
• Rust (v1.74.1)
• Docker (optional, for containerized deployment)

1. Clone the repository:

git clone https://github.com/shardeum/shardeum.git
cd shardeum

2. Install dependencies:

npm ci

3. Network Configuration:

git apply debug-10-nodes.patch

Learn more about the different config options here

4. Compile project

npm run prepare

4. Install the Shardus CLI:

npm install -g shardus
npm update @shardus/archiver

To start a local Shardeum network with 10 nodes, run:

shardus start 10

1. Clone the JSON-RPC server repository:

git clone https://github.com/shardeum/json-rpc-server.git
cd json-rpc-server
npm install

2. Start the server:

npm run start

The default RPC URL is http://localhost:8080.

To test your local Shardeum network using MetaMask:

1. Install the MetaMask extension.
2. Add the Shardeum network to MetaMask:

• Network Name: Shardeum
• RPC URL: http://localhost:8080
• Chain ID: 8082
• Currency Symbol: SHM
• Block Explorer URL: http://localhost:6001/

To stop the network and clean up resources:

shardus stop && shardus clean && rm -rf instances

Diagnostic endpoints to check the health of the node

• GET /is-alive this endpoint returns 200 if the server is running.
• GET /is-healthy currently the same as /is-alive but will be expanded.
