Josh Rickmar 536c1e3c29 Add parameters used by btcd. This change adds two parameters to the Params struct which are used by btcd to alter behavior based on the active network, rather than hardcoding checks for a particular network. The first, ResetMinDifficulty, specifies whether the target difficulty can change between the retarget intervals. The second, RelayNonStdTxs, specifies whether standard transaction checks should not be performed when accepting mempool transactions. The zero values (false) for both of these bools are the correct parameter values for mainnet. While here, rename the test network version 3 to "testnet3", as both btcd and btcwallet will include additional handling to rename this to "testnet" for directory names, and a switch to "testnet3" is planned in the future.	2014-05-23 00:55:21 -05:00

Josh Rickmar 536c1e3c29 Add parameters used by btcd.

This change adds two parameters to the Params struct which are used by
btcd to alter behavior based on the active network, rather than
hardcoding checks for a particular network.

The first, ResetMinDifficulty, specifies whether the target difficulty
can change between the retarget intervals.

The second, RelayNonStdTxs, specifies whether standard transaction
checks should not be performed when accepting mempool transactions.

The zero values (false) for both of these bools are the correct
parameter values for mainnet.

While here, rename the test network version 3 to "testnet3", as both
btcd and btcwallet will include additional handling to rename this to
"testnet" for directory names, and a switch to "testnet3" is planned
in the future.

btcnet

Package btcnet defines the network parameters for the three standard Bitcoin networks and provides the ability for callers to define their own custom Bitcoin networks.

This package is one of the core packages from btcd, an alternative full-node implementation of Bitcoin which is under active development by Conformal. Although it was primarily written for btcd, this package has intentionally been designed so it can be used as a standalone package for any projects needing to use parameters for the standard Bitcoin networks or for projects needing to define their own network.

Sample Use

package main

import (
	"flag"
	"fmt"

	"github.com/conformal/btcnet"
	"github.com/conformal/btcutil"
)

var testnet = flag.Bool("testnet", false, "operate on the testnet Bitcoin network")

// By default (without -testnet), use mainnet.
var netParams = &btcnet.MainNetParams

func main() {
	flag.Parse()

	// Modify active network parameters if operating on testnet.
	if *testnet {
		netParams = &btcnet.TestNet3Params
	}

	// later...

	// Create and print new payment address, specific to the active network.
	pubKeyHash := make([]byte, 20)
	addr, err := btcutil.NewAddressPubKeyHash(pubKeyHash, netParams.Net)
	if err != nil {
		// badness
		return
	}
	fmt.Println(addr)
}

Documentation

Full go doc style documentation for the project can be viewed online without installing this package by using the GoDoc site here.

You can also view the documentation locally once the package is installed with the godoc tool by running godoc -http=":6060" and pointing your browser to http://localhost:6060/pkg/github.com/conformal/btcnet

Installation

$ go get github.com/conformal/btcnet

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 Conformal. 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_NAME is a placeholder for the specific tag:
```
git tag -v TAG_NAME
```
