Gocoin bitcoin software

An open-source Bitcoin solution written in Go language (golang). It can be built for every platform that has a working Go compiler. It uses a proprietary license, though is free to use for non-commercial purposes.

Features

Gocoin has a several unique features, that distinguish it from the original bitcoin client.

Node / Client

• All the unspent outputs are kept in memory, which makes switching between different wallets, as well as checking a balance of any address, relatively fast (few seconds max).
• Allows a user to limit the upload and download network bandwidth used by the client.
• Can be monitored and controlled through a web interface (from a web browser).
• Works with its own implementation of a cold storage wallet.

Wallet

• For security reasons, it is supposed to be used with a PC that has never been (and will never be) connected to a network.
• The wallet is deterministic and a seed-password based. As long as you can remember the password, there is no need for any backups.
• Additionally it can import private keys from an existing bitcoin wallet (that comes in the base58 format).
• Has very low hardware requirements. Can be run on i.e. Raspberry Pi
• Can generate Type-2 deterministic keys/addresses
• Supports signing of P2SH multisig transactions.

Node-less mode

It is possible to use Gocoin's wallet, without a need to have a running client node.

In such a case the required balance files are fetched with a tool called FetchBal, from two popular block explorer services; BlockChain.info and BlockExplorer.com.

Requirements

The client node requires 64-bit platform and at least 4GB of system memory. It also requires a file system that can handle files larger than 4GB.

Limitations

• No GUI, though the online node has web interface
• No RPC API
• No IPv6
• No UPnP

History

Gocoin was written by a single person for a private purposes. The software's first public release was announced in May 2013 on Bitcointalk forum.
