gcash is an alternative full node bitcoin cash implementation written in Go (golang). This project is currently under active development and is in a Beta state.
gcash is a fork repository from btcsuite/btcd, btcd is extremely stable and has been in production use since October 2013.
It properly downloads, validates, and serves the block chain using the exact rules (including consensus bugs) for block acceptance as Bitcoin-ABC. We have taken great care to avoid gcash causing a fork to the block chain. It includes a full block validation testing framework which contains all of the 'official' block acceptance tests (and some additional ones) that is run on every pull request to help ensure it properly follows consensus. Also, it passes all of the JSON test data in the Bitcoin-ABC code.
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 by the block chain and also includes more strict checks which filter transactions based on miner requirements ("standard" transactions).
One key difference between gcash and Bitcoin-ABC is that gcash 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 gcash. That functionality is provided by the cashwallet project which is under active development.
Go 1.8 or newer.
https://github.com/bcext/gcash/releases
-
Install Go according to the installation instructions here: http://golang.org/doc/install
-
Ensure Go was installed properly and is a supported version:
$ go version
$ go env GOROOT GOPATH
NOTE: The GOROOT
and GOPATH
above must not be the same path. It is
recommended that GOPATH
is set to a directory in your home directory such as
~/goprojects
to avoid write permission issues. It is also recommended to add
$GOPATH/bin
to your PATH
at this point.
- Run the following commands to obtain gcash, all dependencies, and install it:
$ go get -u github.com/Masterminds/glide
$ git clone https://github.com/bcext/gcash $GOPATH/src/github.com/bcext/gcash
$ cd $GOPATH/src/github.com/bcext/gcash
$ glide install
$ go install . ./cmd/...
- gcash (and utilities) will now be installed in
$GOPATH/bin
. If you did not already add the bin directory to your system path during Go installation, we recommend you do so now.
Install a newer MSI
- Run the following commands to update gcash, all dependencies, and install it:
$ cd $GOPATH/src/github.com/bcext/gcash
$ git pull && glide install
$ go install . ./cmd/...
gcash has several configuration options available to tweak how it runs, but all of the basic operations described in the intro section work with zero configuration.
Launch gcash from your Start menu.
$ ./gcash

The documentation is a work-in-progress. It is located in the docs folder.
All official release tags are signed by Conformal so users can ensure the code has not been tampered with and is coming from the btcsuite and bcext developers. To verify the signature perform the following:
-
Download the Conformal public key: https://raw.githubusercontent.com/bcext/gcash/master/release/GIT-GPG-KEY-conformal.txt
-
Import the public key into your GPG keyring:
gpg --import GIT-GPG-KEY-conformal.txt
-
Verify the release tag with the following command where
TAG_NAME
is a placeholder for the specific tag:git tag -v TAG_NAME
