This is a blockchain project developed from scratch using Golang. It includes various components such as blocks, transactions, account state, virtual machine, transaction pool, encoding/decoding, API, and ECDSA signature/verification. Additionally, I have implemented the TCP Ghost protocol for the transfer and receipt of transactions and blocks between peers in a peer-to-peer network.
- Blocks: The blockchain consists of a series of blocks, each containing a set of transactions.
- Transactions: Transactions represent the transfer of value between accounts on the blockchain.
- Account State: The current state of each account is maintained, reflecting the balance and other relevant information.
- Virtual Machine: A virtual machine is implemented to execute smart contracts and process transactions.
- Transaction Pool: A transaction pool holds pending transactions that are waiting to be included in a block.
- Encoding/Decoding: The project includes functionality to encode and decode data structures for efficient storage and transmission.
- API: An API is provided to interact with the blockchain, allowing users to submit transactions, query account balances, and retrieve block information.
- ECDSA Signature/Verification: The project includes the implementation of ECDSA (Elliptic Curve Digital Signature Algorithm) for secure transaction signing and verification.
- TCP Ghost Protocol: The TCP Ghost protocol is utilized for the efficient transfer and receipt of transactions and blocks between peers in a peer-to-peer network.
In the future, I plan to make the blockchain compatible with native ERC-721 (NFT) and ERC-20 tokens. This will enable the transfer and management of these tokens on the blockchain.
To get started with this project, follow the steps below:
- Clone the repository:
git clone https://github.com/AnandK-2024/Blockchain_Go.git - Install the required dependencies:
- Build the project:
go build - Run the blockchain node:
go run main.go - Access the API endpoints to interact with the blockchain.
The following API endpoints are available for interacting with the blockchain:
GET /blocks/{blockHash or height}: Retrieve a specific block by its hash or by its block number.POST /tx: Submit a new transaction to the blockchain.GET /tx/{transactionHash}: Retrieve a specific transaction by its hash.GET /accounts/{accountAddress}: Retrieve the account information for a specific address.
