Types

type Chain

type Chain struct {
	BalanceValidationInterval time.Duration
	Cache                     bool
	ConstructionAccessNodes   access.Pool
	DataAccessNodes           access.Pool

}

Chain represents the definition of a Flow chain like mainnet and testnet.

func Init

func Init(ctx context.Context, filename string) *Chain

Init reads the given config file, decodes the JSON config, validates it, and returns the initialized config.

func (*Chain) FirstSpork

func (c *Chain) FirstSpork() *Spork

FirstSpork returns the config for the first spork in the chain.

func (*Chain) IsProxyContractDeployed

func (c *Chain) IsProxyContractDeployed() bool

IsProxyContractDeployed returns whether a deployed Proxy contract has been configured.

func (*Chain) LatestSpork

func (c *Chain) LatestSpork() *Spork

LatestSpork returns the config for the latest spork in the chain.

func (*Chain) PathFor

func (c *Chain) PathFor(subpath ...string) string

PathFor joins the given subpath elements with the chain's data directory.

func (*Chain) SporkFor

func (c *Chain) SporkFor(height uint64) *Spork

SporkFor returns the spork for the given height.

type Consensus

type Consensus struct {
	DisableSignatureCheck         bool       `json:"disable_signature_check"`
	RootProtocolStateURL          string     `json:"root_protocol_state_url"`
	RootProtocolStateSignatureURL string     `json:"root_protocol_state_signature_url"`
	SeedNodes                     []SeedNode `json:"seed_nodes"`
	SigningKey                    string     `json:"signing_key"`
}

Consensus defines the metadata needed to initialize a consensus follower for a live spork.

type Contracts

type Contracts struct {
	FlowFees             string `json:"flow_fees"`
	FlowToken            string `json:"flow_token"`
	FungibleToken        string `json:"fungible_token"`
	FlowColdStorageProxy string `json:"flow_cold_storage_proxy"`
}

Contracts defines the chain-specific addresses for various core contracts.

type SeedNode

type SeedNode struct {
	Host      string `json:"host"`
	Port      uint16 `json:"port"`
	PublicKey string `json:"public_key"`
}

SeedNode defines a seed node for the current spork.

type Spork

type Spork struct {
	AccessNodes access.Pool
	Chain       *Chain
	Consensus   *Consensus
	ID          uint
	Next        *Spork
	Prev        *Spork
	RootBlock   uint64
	Version     int
}

Spork provides the relevant metadata for a spork.

func (*Spork) String

func (s *Spork) String() string
