peer

Package peer provides a common base for creating and managing bitcoin network peers.

This package has intentionally been designed so it can be used as a standalone package for any projects needing a full featured bitcoin peer base to build on.

Overview

This package builds upon the wire package, which provides the fundamental primitives necessary to speak the bitcoin wire protocol, in order to simplify the process of creating fully functional peers. In essence, it provides a common base for creating concurrent safe fully validating nodes, Simplified Payment Verification (SPV) nodes, proxies, etc.

A quick overview of the major features peer provides are as follows:

Provides a basic concurrent safe bitcoin peer for handling bitcoin communications via the peer-to-peer protocol
Full duplex reading and writing of bitcoin protocol messages
Automatic handling of the initial handshake process including protocol version negotiation
Asynchronous message queueing of outbound messages with optional channel for notification when the message is actually sent
Flexible peer configuration
- Caller is responsible for creating outgoing connections and listening for incoming connections so they have flexibility to establish connections as they see fit (proxies, etc)
- User agent name and version
- Bitcoin network
- Service support signalling (full nodes, bloom filters, etc)
- Maximum supported protocol version
- Ability to register callbacks for handling bitcoin protocol messages
Inventory message batching and send trickling with known inventory detection and avoidance
Automatic periodic keep-alive pinging and pong responses
Random nonce generation and self connection detection
Proper handling of bloom filter related commands when the caller does not specify the related flag to signal support
- Disconnects the peer when the protocol version is high enough
- Does not invoke the related callbacks for older protocol versions
Snapshottable peer statistics such as the total number of bytes read and written, the remote address, user agent, and negotiated protocol version
Helper functions pushing addresses, getblocks, getheaders, and reject messages
- These could all be sent manually via the standard message output function, but the helpers provide additional nice functionality such as duplicate filtering and address randomization
Ability to wait for shutdown/disconnect
Comprehensive test coverage

Installation and Updating

$ go get -u github.com/daglabs/btcd/peer

Examples

New Outbound Peer Example
Demonstrates the basic process for initializing and creating an outbound peer. Peers negotiate by exchanging version and verack messages. For demonstration, a simple handler for the version message is attached to the peer.
