This is a collection of simple programs which can generate bitcoin wallets, create and sign transactions, and send transactions over the bitcoin network.
It was a learning project for me to learn more about both golang, and the bitcoin protocol.
This project consists of three programs which each contain the most basic usecase.
- keys.go - Generates a public/private key pair
- transaction.go - Creates, and signs a bitcoin transaction
- network.go - Connects to a peer, and sends a transaction over the network
These programs are not "crytographically" random, and should not be used for any purpose other than educational use.
- Install go
go getto install dependencies
- Follow the instructions at go-secp256k1 to compile bitcoin/c-secp256k1
- Run one of the programs using the syntax below
Creating a key pair
go run keys.go options (optional) --testnet
Generating a transaction
go run transaction.go options (required) --private-key yourPrivateKey --public-key yourPublicKey --destination destinationPublicKey --input-transaction inputTransactionHash --satoshis satoshisToSend options (optional) --input-index inputTransactionIndex
Sending a transaction over the bitcoin network
go run network.go options (required) --transaction yourTransaction --node-address 255.255.255.255 (IPv4 address of the bitcoin node to connect to) --network-address 255.255.255.255 (IPv4 address of your public IP address) options (optional) --testnet
This library is used for the creation of public keys from private keys, as well as signing transactions. It is a project which wraps the official bitcoin/c-secp256k1 bitcoin library.
This library does the base58 conversion. I have included the base58 project in this codebase rather than importing it from the aforementioned github, because I needed to change the dictionary that was used.
