# Layer 2 Blockchain A layer 2 blockchain implementation that provides fast and cheap transactions using off-chain computation. ## Table of Contents - [Installation](#installation) - [Usage](#usage) - [Architecture](#architecture) - [Contributing](#contributing) - [License](#license) - [Contact](#contact) ## Installation To install the layer 2 blockchain, follow these steps: 1. Clone the repository: ``` git clone https://github.com/yourusername/layer2-blockchain.git ``` 2. Install dependencies: ``` cd layer2-blockchain npm install ``` 3. Start the blockchain: ``` npm start ``` The blockchain will start running on `http://localhost:3000`. ## Usage To interact with the layer 2 blockchain, you can use a web3 provider like MetaMask or a command-line tool like `web3.js`. Here are some example commands you can use to interact with the blockchain: - Create a new account: ``` curl -H "Content-Type: application/json" -X POST -d '{"password":"mypassword"}' http://localhost:3000/accounts ``` - Send a transaction: ``` curl -H "Content-Type: application/json" -X POST -d '{"from":"0x1234567890123456789012345678901234567890","to":"0x0987654321098765432109876543210987654321","value":100}' http://localhost:3000/transactions ``` - Get account balance: ``` curl -H "Content-Type: application/json" -X GET http://localhost:3000/accounts/0x1234567890123456789012345678901234567890/balance ``` ## Architecture The layer 2 blockchain uses a combination of on-chain and off-chain computation to achieve fast and cheap transactions. Here is an overview of the architecture: - Smart contracts on the main Ethereum blockchain handle account creation and management. - Transactions are signed by users and then submitted to a decentralized network of nodes for off-chain processing. - Nodes validate and execute transactions off-chain, and then submit them back to the main Ethereum blockchain for settlement. ## Contributing Contributions to the layer 2 blockchain are welcome!
