Functions

func ArchiveVersion 

func ArchiveVersion(gitCommit string) string

ArchiveVersion holds the textual version string used for Geth archives. e.g. "1.8.11-dea1ce05" for stable releases, or

func VersionWithCommit 

func VersionWithCommit(gitCommit string) string

Types

type BaseConfig 

type BaseConfig struct {
	// A custom human readable name for this node
	Moniker string `mapstructure:"moniker"`

	// If true, query the ABCI app on connecting to a new peer
	// so the app can decide if we should keep the connection or not
	FilterPeers bool `mapstructure:"filter_peers"` // false
}

BaseConfig defines the base configuration for a truechain node

func DefaultBaseConfig 

func DefaultBaseConfig() BaseConfig

DefaultBaseConfig returns a default base configuration for a truechain node

func TestBaseConfig 

func TestBaseConfig() BaseConfig

TestBaseConfig returns a base configuration for testing a truechain node

type ChainConfig 

type ChainConfig struct {
	ChainID *big.Int `json:"chainId"` // chainId identifies the current chain and is used for replay protection

	// Various consensus engines
	Minerva *MinervaConfig `json:"minerva"`
}

ChainConfig is the core config which determines the blockchain settings.

ChainConfig is stored in the database on a per block basis. This means that any network, identified by its genesis block, can have its own set of configuration options.
