gagchain (Gagcoin)

Experimental blockchain built in Golang. It is still under development and features will be updated regulary.

Features

• Custom TCP server for communication with nodes
• Custom Database built only to store the current chain
• Custom communication messages to communicate with other nodes
• Verifying node authenticity by its address
• Concurrency
• Easy to compile and run

Using this for your own blockchain project

If you use this as a template, please do not remove any credits, and I expect to be credited in a README file or something similar. You can always run your own node, just setup the variables that are found in the main.go file (root directory).

Usage

WHen you run a node, you can do the following things;

Init blockchain;

blockchain.InitBlockchain()

Or: &blockchain.Blockchain{chain []*blockchain.Block}

Init Transaction Pool;

blockchain.NewTransactionPool()

Add Block to the blockchain (this also mines it if;

• The Miner field is ""
• config.Mining_Node = true

(*blockchain.Blockchain).AddBlock(data []*blockchain.Transaction, hash []byte, nonce int, Miner string)

Add transaction to the Transaction Pool;

(*blockchain.TransactionPool).AddTransaction(transaction *blockchain.Transaction)

New Transaction;

(*blockchain.Blockchain).NewTransactionInstance(from *ecdsa.PublicKey, to string, amount int)

Mine Transactions from Transaction Pool;

(*blockchain.TransactionPool).MineTransactions()
