Params Params // feed_configs stores all of the supported OCR feeds FeedConfigs []*FeedConfig // latest_epoch_and_rounds stores the latest epoch and round for each feedId LatestEpochAndRounds []*FeedEpochAndRound // feed_transmissions stores the last transmission for each feed FeedTransmissions []*FeedTransmission // latest_aggregator_round_ids stores the latest aggregator round ID for each feedId LatestAggregatorRoundIds []*FeedLatestAggregatorRoundIDs // reward_pools stores the reward pools RewardPools []*RewardPool // feed_observation_counts stores the feed observation counts FeedObservationCounts []*FeedCounts // feed_transmission_counts stores the feed transmission counts FeedTransmissionCounts []*FeedCounts // pending_payeeships stores the pending payeeships PendingPayeeships []*PendingPayeeship } ``` ## Params `Params` is a module-wide configuration that stores system parameters and defines overall functioning of the ocr module. This module is modifiable by governance using params update proposal natively supported by `gov` module. Struct for the `ocr` module params store. ```go theme={null} type Params struct { // Native denom for LINK coin in the bank keeper LinkDenom string // The block number interval at which payouts are made PayoutBlockInterval uint64 // The admin for the OCR module ModuleAdmin string } ``` ## FeedConfig `FeedConfig` is to manage the configurations of feed and it exists one per feed. ```go theme={null} type FeedConfig struct { // signers ith element is address ith oracle uses to sign a report Signers []string // transmitters ith element is address ith oracle uses to transmit a report via the transmit method Transmitters []string // f maximum number of faulty/dishonest oracles the protocol can tolerate while still working correctly F uint32 // onchain_config contains properties relevant only for the Cosmos module. OnchainConfig *OnchainConfig // offchain_config_version version of the serialization format used for "offchain_config" parameter OffchainConfigVersion uint64 // offchain_config serialized data used by oracles to configure their offchain operation OffchainConfig []byte } ``` ### FeedConfigInfo `FeedConfigInfo` is storing the information that needs to be updated more often for each transmission event. ```go theme={null} type FeedConfigInfo struct { LatestConfigDigest []byte F uint32 N uint32 // config_count ordinal number of this config setting among all config settings ConfigCount uint64 LatestConfigBlockNumber int64 } ``` ### Transmission `Transmission` is the unit to save transition information on the store. ```go theme={null} // Transmission records the median answer from the transmit transaction at // time timestamp type Transmission struct { Answer math.LegacyDec ObservationsTimestamp int64 TransmissionTimestamp int64 } ``` ### Report `Report` is the unit to save report information on the store. ```go theme={null} type Report struct { ObservationsTimestamp int64 Observers []byte Observations []math.LegacyDec } ``` `ReportToSign` saves the information that needs to be signed by observers. ```go theme={null} type ReportToSign struct { ConfigDigest []byte Epoch uint64 Round uint64 ExtraHash []byte // Opaque report Report []byte } ``` ### OnchainConfig `OnchainConfig` saves the configuration that needs to be managed on-chain for feed config. ```go theme={null} type OnchainConfig struct { // chain_id the ID of the Cosmos chain itself. ChainId string // feed_id is an unique ID for the target of this config FeedId string // lowest answer the median of a report is allowed to be MinAnswer math.LegacyDec // highest answer the median of a report is allowed to be MaxAnswer math.LegacyDec // Fixed LINK reward for each observer LinkPerObservation math.Int // Fixed LINK reward for transmitter LinkPerTransmission math.Int // Native denom for LINK coin in the bank keeper LinkDenom string // Enables unique reports UniqueReports bool // short human-readable description of observable this feed's answers pertain to Description string // feed administrator FeedAdmin string // feed billing administrator BillingAdmin string } ``` ### ContractConfig `ContractConfig` saves the configuration that is related to contract to store OCR. ```go theme={null} type ContractConfig struct { // config_count ordinal number of this config setting among all config settings ConfigCount uint64 // signers ith element is address ith oracle uses to sign a report Signers []string // transmitters ith element is address ith oracle uses to transmit a report via the transmit method Transmitters []string // f maximum number of faulty/dishonest oracles the protocol can tolerate while still working correctly F uint32 // onchain_config serialized config that is relevant only for the module. OnchainConfig []byte // offchain_config_version version of the serialization format used for "offchain_config" parameter OffchainConfigVersion uint64 // offchain_config serialized data used by oracles to configure their offchain operation OffchainConfig []byte } ``` ### FeedProperties `FeedProperties` is a unit to store the properties of feed by id. ```go theme={null} type FeedProperties struct { // feed_id is an unique ID for the target of this config FeedId string // f maximum number of faulty/dishonest oracles the protocol can tolerate while still working correctly F uint32 // offchain_config_version version of the serialization format used for "offchain_config" parameter OffchainConfigVersion uint64 // offchain_config serialized data used by oracles to configure their offchain operation OffchainConfig []byte // lowest answer the median of a report is allowed to be MinAnswer math.LegacyDec // highest answer the median of a report is allowed to be MaxAnswer math.LegacyDec // Fixed LINK reward for each observer LinkPerObservation math.Int // Fixed LINK reward for transmitter LinkPerTransmission math.Int // Enables unique reports UniqueReports bool // short human-readable description of observable this feed's answers pertain to Description string } ``` ### PendingPayeeship `PendingPayeeship` is a record that is stored when a person is delegating payeeship to another address. When proposed payee accept this, this record is removed. ```go theme={null} type PendingPayeeship struct { FeedId string Transmitter string ProposedPayee string } ```
