A collection of simple Go programs for generating Bitcoin wallets, creating/signing transactions, and sending them over the network.
HelloBitcoin is a collection of simple Go programs that demonstrate fundamental Bitcoin operations including wallet generation, transaction creation and signing, and network broadcasting. It serves as an educational tool for developers who want to understand the Bitcoin protocol at a low level by working with raw keys, transactions, and peer-to-peer communication.
Developers and students learning about Bitcoin's technical implementation, particularly those interested in Go programming and cryptocurrency protocol internals.
It provides minimal, focused examples that isolate core Bitcoin concepts, making complex operations like transaction signing and network propagation accessible for educational purposes without the overhead of full wallet software.
A collection of simple programs which can generate bitcoin wallets, create and sign transactions, and send transactions over the bitcoin network.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Each program isolates a single Bitcoin operation, such as key generation or transaction signing, making it easy to learn step-by-step without unnecessary complexity.
Demonstrates raw Bitcoin network communication and transaction building using the peer-to-peer protocol, providing hands-on insight into the protocol's inner workings.
Includes optional testnet mode in the usage options, allowing for risk-free experimentation without using real Bitcoin.
Consists of only three main programs (keys.go, transaction.go, network.go), keeping the learning curve manageable and the focus on core concepts.
The disclaimer explicitly states that key generation is not cryptographically random, making it unsafe for any real-world or production use.
Requires compiling external libraries like go-secp256k1, which involves additional steps beyond standard Go installations, as noted in the installation instructions.
Only covers basic Bitcoin operations; lacks support for modern features such as SegWit, BIP32 hierarchical deterministic wallets, or advanced transaction types.
