This introduces the concept of a new interface named TxSource which aims to generically provide a concurrent safe source of transactions to be considered for inclusion in a new block. This is a step towards decoupling the mining code from the internals of btcd. Ultimately the intent is to create a separate mining package. The new TxSource interface relies on a new struct named miningTxDesc, which describes each entry in the transaction source. Once this code is refactored into a separate mining package, the mining prefix can simply be dropped leaving the type exported as mining.TxDesc. To go along with this, the existing TxDesc type in the mempool has been renamed to mempoolTxDesc and changed to embed the new miningTxDesc type. This allows the mempool to efficiently implement the MiningTxDescs method needed to satisfy the TxSource interface. This approach effectively separates the direct reliance of the mining code on the mempool and its data structures. Even though the memory pool will still be the default concrete implementation of the interface, making it an interface offers much more flexibility in terms of testing and even provides the potential to allow more than one source (perhaps multiple independent relay networks, for example). Finally, the memory pool and all of the mining code has been updated to implement and use the new interface. |

btcd

(https://travis-ci.org/btcsuite/btcd)
btcd is an alternative full node bitcoin implementation written in Go (golang).
This project is currently under active development and is in a Beta state. It is extremely stable and has been in production use for over 6 months as of May 2014, however there are still a couple of major features we want to add before we come out of beta.
It properly downloads, validates, and serves the block chain using the exact rules (including bugs) for block acceptance as Bitcoin Core. 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) as well as all of the JSON test data in the Bitcoin Core code.
It also relays newly mined blocks, maintains a transaction pool, and relays individual transactions that have not yet made it into a block. It ensures all transactions admitted to the pool follow the rules required by the block chain and also includes the same checks which filter transactions based on miner requirements ("standard" transactions) as Bitcoin Core.
One key difference between btcd and Bitcoin Core 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.
Requirements
Go 1.3 or newer.
Installation
Windows - MSI Available
https://github.com/btcsuite/btcd/releases
Linux/BSD/MacOSX/POSIX - Build from Source
-
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.
- Run the following command to obtain btcd, all dependencies, and install it:
$ go get -u github.com/btcsuite/btcd/...
- btcd (and utilities) will now be installed in either
$GOROOT/binor$GOPATH/bindepending on your configuration. If you did not already add the bin directory to your system path during Go installation, we recommend you do so now.
Updating
Windows
Install a newer MSI
Linux/BSD/MacOSX/POSIX - Build from Source
- Run the following command to update btcd, all dependencies, and install it:
$ go get -u -v github.com/btcsuite/btcd/...
Getting Started
btcd has several configuration options avilable to tweak how it runs, but all of the basic operations described in the intro section work with zero configuration.
Windows (Installed from MSI)
Launch btcd from your Start menu.
Linux/BSD/POSIX/Source
$ ./btcd
IRC

Documentation
The documentation is a work-in-progress. It is located in the docs folder.
GPG Verification Key
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 developers. To verify the signature perform the following:
-
Download the public key from the Conformal website at https://opensource.conformal.com/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_NAMEis a placeholder for the specific tag:git tag -v TAG_NAME
