type PublicConfig

type PublicConfig struct {
	// If an epoch (driven by a leader) fails to achieve progress (generate a
	// report) after DeltaProgress, we enter a new epoch. This parameter must be
	// chosen carefully. If the duration is too short, we may keep prematurely
	// switching epochs without ever achieving any progress, resulting in a
	// liveness failure!
	DeltaProgress time.Duration
	// DeltaResend determines how often Pacemaker newepoch messages should be
	// resent, allowing oracles that had crashed and are recovering to rejoin
	// the protocol more quickly. ~30s should be a reasonable default under most
	// circumstances.
	DeltaResend time.Duration
	// DeltaRound determines the minimal amount of time that should pass between
	// the start of report generation rounds. With OCR2 only (not OCR1!) you can
	// set this value very aggressively. Note that this only provides a lower
	// bound on the round interval; actual rounds might take longer.
	DeltaRound time.Duration
	// Once the leader of a report generation round has collected sufficiently
	// many observations, it will wait for DeltaGrace to pass to allow slower
	// oracles to still contribute an observation before moving on to generating
	// the report. Consequently, rounds driven by correct leaders will always
	// take at least DeltaGrace.
	DeltaGrace time.Duration
	// DeltaStage determines the duration between stages of the transmission
	// protocol. In each stage, a certain number of oracles (determined by S)
	// will attempt to transmit, assuming that no other oracle has yet
	// successfully transmitted a report.
	DeltaStage time.Duration
	// The maximum number of rounds during an epoch.
	RMax uint64
	// S is the transmission schedule. For example, S = [1,2,3] indicates that
	// in the first stage of transmission one oracle will attempt to transmit,
	// in the second stage two more will attempt to transmit (if in their view
	// the first stage didn't succeed), and in the third stage three more will
	// attempt to transmit (if in their view the first and second stage didn't
	// succeed).

	// MaxDurationX is the maximum duration a ReportingPlugin should spend
	// performing X. Reasonable values for these will be specific to each
	// ReportingPlugin. Be sure to not set these too short, or the corresponding

PublicConfig is the configuration disseminated through the smart contract It's public, because anybody can read it from the blockchain

func PublicConfigFromContractConfig

func PublicConfigFromContractConfig(skipResourceExhaustionChecks bool, change types.ContractConfig) (PublicConfig, error)

func (*PublicConfig) CheckParameterBounds

func (c *PublicConfig) CheckParameterBounds() error

func (*PublicConfig) N

func (c *PublicConfig) N() int

N is the number of oracles participating in the protocol

type SharedConfig

type SharedConfig struct {
	PublicConfig
	SharedSecret *[config.SharedSecretSize]byte
}

SharedConfig is the configuration shared by all oracles running an instance of the protocol. It's disseminated through the smart contract, but parts of it are encrypted so that only oracles can access them.
