Package chaincfg defines chain configuration parameters for the three standard Decred networks and provides the ability for callers to define their own custom Decred networks.
Although this package was primarily written for dcrd, it has intentionally been designed so it can be used as a standalone package for any projects needing to use parameters for the standard Decred networks or for projects needing to define their own network.
Sample Use
package main
import (
"flag"
"fmt"
"log"
"github.com/decred/dcrutil"
"github.com/decred/dcrd/chaincfg"
)
var testnet = flag.Bool("testnet", false, "operate on the testnet Decred 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.TestNetParams
}
// 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)
}

Overview ¶
Package chaincfg defines chain configuration parameters.
In addition to the main Decred network, which is intended for the transfer of monetary value, there also exists two currently active standard networks: regression test and testnet (version 0). These networks are incompatible with each other (each sharing a different genesis block) and software should handle errors where input intended for one network is used on an application instance running on a different network.
For library packages, chaincfg provides the ability to lookup chain parameters and encoding magics when passed a *Params. Older APIs not updated to the new convention of passing a *Params may lookup the parameters for a wire.DecredNet using ParamsForNet, but be aware that this usage is deprecated and will be removed from chaincfg in the future.
For main packages, a (typically global) var may be assigned the address of one of the standard Param vars for use as the application's "active" network. When a network parameter is needed, it may then be looked up through this variable (either directly, or hidden in a library call).
package main
import (
"flag"
"fmt"
"log"
"github.com/decred/dcrutil"
"github.com/decred/dcrd/chaincfg"
)
var testnet = flag.Bool("testnet", false, "operate on the testnet Decred 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.TestNetParams
}
// later...
// Create and print new payment address, specific to the active network.
pubKeyHash := make([]byte, 20)
addr, err := dcrutil.NewAddressPubKeyHash(pubKeyHash, chainParams)
if err != nil {
log.Fatal(err)
}
fmt.Println(addr)
}
If an application does not use one of the three standard Decred networks, a new Params struct may be created which defines the parameters for the non-standard network. As a general rule of thumb, all network parameters should be unique to the network, but parameter collisions can still occur (unfortunately, this is the case with regtest and testnet sharing magics).

Variables ¶
var ( // ErrDuplicateNet describes an error where the parameters for a Decred // network could not be set due to the network already being a standard // network or previously-registered into this package. ErrDuplicateNet = errors.New("duplicate Decred network") // ErrUnknownHDKeyID describes an error where the provided id which // is intended to identify the network for a hierarchical deterministic // private extended key is not registered. ErrUnknownHDKeyID = errors.New("unknown hd private extended key bytes") )
var BlockOneLedgerMainNet = []*TokenPayout{}/* 3146 elements not displayed */
BlockOneLedgerMainNet is the block one output ledger for the main network.
var BlockOneLedgerSimNet = []*TokenPayout{
{"Sshw6S86G2bV6W32cbc7EhtFy8f93rU6pae", 100000 * 1e8},

{"SsfXiYkYkCoo31CuVQw428N6wWKus2ZEw5X", 100000 * 1e8},
}
BlockOneLedgerSimNet is the block one output ledger for the simulation network. See under "Decred organization related parameters" in params.go for information on how to spend these outputs.
var BlockOneLedgerTestNet = []*TokenPayout{
{"TsmWaPM77WSyA3aiQ2Q1KnwGDVWvEkhipBc", 100000 * 1e8},
}
BlockOneLedgerTestNet is the block one output ledger for the test network.
var CPUMinerThreads = 1
CPUMinerThreads is the default number of threads to utilize with the CPUMiner when mining.
var CheckForDuplicateHashes = false
CheckForDuplicateHashes checks for duplicate hashes when validating blocks. Because of the rule inserting the height into the second (nonce) txOut, there should never be a duplicate transaction hash that overwrites another. However, because there is a 2^128 chance of a collision, the paranoid user may wish to turn this feature on.

MainNetParams defines the network parameters for the main Decred network.
var SigHashOptimization = false
SigHashOptimization is an optimization for verification of transactions that do CHECKSIG operations with hashType SIGHASH_ALL. Although there should be no consequences to daemons that are simply running a node, it may be the case that you could cause database corruption if you turn this code on, create and manipulate your own MsgTx, then include them in blocks. For safety, if you're using the daemon with wallet or mining with the daemon this should be disabled. If you believe that any MsgTxs in your daemon will be used mutably, do NOT turn on this feature. It is disabled by default. This feature is considered EXPERIMENTAL, enable at your own risk!

SimNetParams defines the network parameters for the simulation test Decred network. This network is similar to the normal test network except it is intended for private use within a group of individuals doing simulation testing. The functionality is intended to differ in that the only nodes which are specifically specified are used to create the network rather than following normal discovery rules. This is important as otherwise it would just turn into another public testnet.

TestNetParams defines the network parameters for the test currency network. This network is sometimes simply called "testnet".
Functions ¶
func HDPrivateKeyToPublicKeyID ¶
HDPrivateKeyToPublicKeyID accepts a private hierarchical deterministic extended key id and returns the associated public key id. When the provided id is not registered, the ErrUnknownHDKeyID error will be returned.
func IsPKHEdwardsAddrID ¶
IsPKHEdwardsAddrID returns whether the id is an identifier know to prefix a pay-to-pubkey-hash Edwards address.
func IsPKHSchnorrAddrID ¶
IsPKHSchnorrAddrID returns whether the id is an identifier know to prefix a pay-to-pubkey-hash secp256k1 Schnorr address.
func IsPubKeyAddrID ¶
IsPubKeyAddrID returns whether the id is an identifier known to prefix a pay-to-pubkey address on any default or registered network.
func IsPubKeyHashAddrID ¶
IsPubKeyHashAddrID returns whether the id is an identifier known to prefix a pay-to-pubkey-hash address on any default or registered network. This is used when decoding an address string into a specific address type. It is up to the caller to check both this and IsScriptHashAddrID and decide whether an address is a pubkey hash address, script hash address, neither, or undeterminable (if both return true).
func IsScriptHashAddrID ¶
IsScriptHashAddrID returns whether the id is an identifier known to prefix a pay-to-script-hash address on any default or registered network. This is used when decoding an address string into a specific address type. It is up to the caller to check both this and IsPubKeyHashAddrID and decide whether an address is a pubkey hash address, script hash address, neither, or undeterminable (if both return true).
func Register ¶
Register registers the network parameters for a Decred network. This may error with ErrDuplicateNet if the network is already registered (either due to a previous Register call, or the network being one of the default networks).
Network parameters should be registered into this package by a main package as early as possible. Then, library packages may lookup networks or network parameters based on inputs and work regardless of the network being standard or not.
Types ¶
type Checkpoint ¶
Checkpoint identifies a known good point in the block chain. Using checkpoints allows a few optimizations for old blocks during initial download and also prevents forks from old blocks.
Each checkpoint is selected based upon several factors. See the documentation for chain.IsCheckpointCandidate for details on the selection criteria.
