btcd

[] (https://travis-ci.org/conformal/btcd)

btcd is an alternative full node bitcoin implementation written in Go (golang).

This project is currently under active development and is in an Alpha state.

It currently properly downloads, validates, and serves the block chain using the exact rules (including bugs) for block acceptance as the reference implementation (bitcoind). We have taken great care to avoid btcd causing a fork to the block chain. It passes all of the 'official' block acceptance tests (https://github.com/TheBlueMatt/test-scripts).

It also properly relays newly mined blocks, maintains a transaction pool, and relays individual transactions that have not yet made it into a block. It ensures all individual transactions admitted to the pool follow the rules required into the block chain and also includes the vast majority of the more strict checks which filter transactions based on miner requirements ("standard" transactions).

One key difference between btcd and bitcoind is that btcd does NOT include wallet functionality and this was a very intentional design decision. See the blog entry here for more details. This means you can't actually make or receive payments directly with btcd. That functionality is provided by the btcwallet and btcgui projects which are both under active development.
