TestNetParams defines the network parameters for the test flow network. Not to be confused with the regression test network, this network is sometimes simply called "testnet".

Functions

func FileExists 

func FileExists(name string) bool

filesExists reports whether the named file or directory exists.

func LoadGenesis 

func LoadGenesis(path string) error

LoadGenesis loads genesis data from the given path

func ParseAndSetDebugLevels 

func ParseAndSetDebugLevels(debugLevel string) error

ParseAndSetDebugLevels attempts to parse the specified debug level and set the levels accordingly. An appropriate error is returned if anything is invalid.

func Register 

func Register(params *Params) error

Register registers the network parameters for a Bitcoin 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.

func TransferGenesisData 

func TransferGenesisData(data []byte) map[string][]ContractInfo

Decode a bytes array into a map, it is only used for genesis block's data.

func Version 

func Version() string

Version returns the application Version as a properly formed string per the semantic versioning 2.0.0 spec (http://semver.org/).

Types

type BitcoinParams 

type BitcoinParams struct {
	Host        string
	RpcUser     string
	RpcPassword string
}

type Checkpoint 

type Checkpoint struct {
	Height int32
	Hash   *common.Hash
}

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 blockchain.IsCheckpointCandidate for details on the selection criteria.

type ConsensusDeployment 

type ConsensusDeployment struct {
	// BitNumber defines the specific bit number within the block version
	// this particular soft-fork deployment refers to.
	BitNumber uint8

	// StartTime is the median block time after which voting on the
	// deployment starts.
	StartTime int64

	// ExpireTime is the median block time after which the attempted
	// deployment expires.
	ExpireTime int64
}

ConsensusDeployment defines details related to a specific consensus rule change that is voted in. This is part of BIP0009.

type ContractInfo 

type ContractInfo struct {
	// name of contract
	Name string
	// an address for some contract instance
	Address []byte
	// compiled code for contract, contains ctor and params.
	Code string
	// abis for contract
	AbiInfo string
	// init params
	InitCode string
	// block height where the contract active.
	BlockHeight int32
}

ContractInfo defines all fields for a contract.

type DNSSeed 

type DNSSeed struct {
	// Host defines the hostname of the seed.
	Host string

	// HasFiltering defines whether the seed supports filtering
	// by service flags (wire.ServiceFlag).
	HasFiltering bool
}

DNSSeed identifies a DNS seed.

func (DNSSeed) String 

func (d DNSSeed) String() string

String returns the hostname of the DNS seed in human-readable form.

FConfig defines the configuration options for asimovd.

See loadConfig for details on the configuration load process.

func LoadConfig 

func LoadConfig() (*FConfig, []string, error)

loadConfig initializes and parses the FConfig using a FConfig file and command line options.

The configuration proceeds as follows:

  1. Start with a default FConfig with sane settings
  2. Pre-parse the command line to check for an alternative FConfig file
  3. Load configuration file overwriting defaults with any specified options
  4. Parse CLI options and overwrite/add any specified options

The above results in btcd functioning properly without any FConfig settings while still allowing the user to override settings with FConfig files and command line options. Command line options always take precedence.
