Params defines the module parameters for the x/oracle module.

Fields

vote_period: u64

VotePeriod defines the number of blocks during which voting takes place.

vote_threshold: String

VoteThreshold specifies the minimum proportion of votes that must be received for a ballot to pass.

reward_band: String

RewardBand defines a maxium divergence that a price vote can have from the weighted median in the ballot. If a vote lies within the valid range defined by: μ := weightedMedian, validRange := μ ± (μ * rewardBand / 2), then rewards are added to the validator performance. Note that if the reward band is smaller than 1 standard deviation, the band is taken to be 1 standard deviation.a price

whitelist: Vec<String>

The set of whitelisted markets, or asset pairs, for the module. Ex. ‘[“unibi:uusd”,“ubtc:uusd”]’

slash_fraction: String

SlashFraction returns the proportion of an oracle’s stake that gets slashed in the event of slashing. SlashFraction specifies the exact penalty for failing a voting period.

slash_window: u64

SlashWindow returns the number of voting periods that specify a “slash window”. After each slash window, all oracles that have missed more than the penalty threshold are slashed. Missing the penalty threshold is synonymous with submitting fewer valid votes than MinValidPerWindow.

min_valid_per_window: String

twap_lookback_window: Option<Duration>

Amount of time to look back for TWAP calculations. Ex: “900.000000069s” corresponds to 900 seconds and 69 nanoseconds in JSON.

min_voters: u64

The minimum number of voters (i.e. oracle validators) per pair for it to be considered a passing ballot. Recommended at least 4.

validator_fee_ratio: String

The validator fee ratio that is given to validators every epoch.

expiration_blocks: u64

Trait Implementations

impl Clone for Params

fn clone(&self) -> Params

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Params

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Params

fn default() -> Self

Returns the “default value” for a type.

impl Message for Params

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Params

fn eq(&self, other: &Params) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
