## What it is
Bitcoin Core is the reference full-node implementation of the Bitcoin peer-to-peer network, fully downloading and validating blocks and transactions. It also includes an optional wallet and graphical user interface, and serves as the integration/staging tree for Bitcoin protocol development.

## Use cases
- run a fully validating bitcoin full node
- store and manage bitcoin in a self-custodial wallet
- query blockchain data via RPC for applications
- develop and test changes to the bitcoin protocol
- verify bitcoin transactions independently without trusting third parties

## When to choose
- you need to validate the bitcoin blockchain yourself with maximum security and privacy
- you want the canonical, most reviewed bitcoin implementation
- you need a full node with wallet and RPC interface for bitcoin infrastructure

## When to avoid
- you only want a lightweight wallet without downloading the blockchain
- you need a block explorer or analytics service rather than node software
- you work with other cryptocurrencies or tokens

## Facets
- artifact type: application
- maturity: stable
- function: cryptography, networking, p2p, cli, gui, rpc
- domain: blockchain, security, cross-platform
- platform: windows, cross-platform, cpp
- tags: bitcoin, full-node, blockchain, wallet, libsecp256k1, cryptocurrency, linux, macos
