Package chaincfg defines chain configuration parameters for the three standard
|
|
Bitcoin networks and provides the ability for callers to define their own custom
|
|
Bitcoin networks.
|
|
|
|
Although this package was primarily written for btcd, it 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
|
|
|
|
```Go
|
|
package main
|
|
|
|
import (
|
|
"flag"
|
|
"fmt"
|
|
"log"
|
|
|
|
"github.com/btcsuite/btcutil"
|
|
"github.com/btcsuite/btcd/chaincfg"
|
|
)
|
|
|
|
var testnet = flag.Bool("testnet", false, "operate on the testnet Bitcoin network")
|
|
|
|
// By default (without -testnet), use mainnet.
|
|
var chainParams = &chaincfg.MainNetParams
|
|
|
|
func main() {
|
|
flag.Parse()
|
|
|
|
// Modify active network parameters if operating on testnet.
|
|
if *testnet {
|
|
chainParams = &chaincfg.TestNet3Params
|
|
}
|
|
|
|
// later...
|
|
|
|
// Create and print new payment address, specific to the active network.
|
|
pubKeyHash := make([]byte, 20)
|
|
addr, err := btcutil.NewAddressPubKeyHash(pubKeyHash, chainParams)
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
fmt.Println(addr)
|
|
}
|
|
```

(http://godoc.org/github.com/btcsuite/btcd/chaincfg)
|
|
|
|
Full `go doc` style documentation for the project can be viewed online without
|
|
installing this package by using the GoDoc site
|
|
[here](http://godoc.org/github.com/btcsuite/btcd/chaincfg).
|
|
|
|
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/btcsuite/btcd/chaincfg
|
|
|
|
## Installation

|
|
|
```bash
|
|
$ go get github.com/btcsuite/btcd/chaincfg
|
|
```
|
|
|
|
## 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:
|
|
```bash
|
|
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:
|
|
```bash
|
|
git tag -v TAG_NAME
|
|
```
