消息
MsgRelayBandRates
授权的Band中继者可以通过MsgRelayBandRates消息中继多个符号的价格源数据。注册的处理程序遍历MsgRelayBandRates中存在的所有符号，并为每个符号创建/更新BandPriceState。
message MsgRelayBandRates {
string relayer = 1;
repeated string symbols = 2;
repeated uint64 rates = 3;
repeated uint64 resolve_times = 4;
repeated uint64 requestIDs = 5;
}如果中继者不是授权的Band中继者，此消息预期会失败。
MsgRelayCoinbaseMessages
Coinbase提供者的中继者可以使用MsgRelayCoinbaseMessages消息发送价格数据。
每个Coinbase消息通过Coinbase oracle地址0xfCEAdAFab14d46e20144F48824d0C09B1a03F2BC提供的签名进行身份验证，从而允许任何人提交MsgRelayCoinbaseMessages。
message MsgRelayCoinbaseMessages {
option (gogoproto.equal) = false;
option (gogoproto.goproto_getters) = false;
string sender = 1;
repeated bytes messages = 2;
repeated bytes signatures = 3;
}如果签名验证失败，或者提交的时间戳比最后一次提交的Coinbase价格更旧，则此消息预期会失败。
MsgRelayPriceFeedPrice
价格源提供者的中继者可以使用MsgRelayPriceFeedPrice消息发送价格源数据。
// MsgRelayPriceFeedPrice defines a SDK message for setting a price through the pricefeed oracle.
message MsgRelayPriceFeedPrice {
option (gogoproto.equal) = false;
option (gogoproto.goproto_getters) = false;
string sender = 1;
repeated string base = 2;
repeated string quote = 3;
// price defines the price of the oracle base and quote
repeated string price = 4 [
(gogoproto.customtype) = "cosmossdk.io/math.LegacyDec",
(gogoproto.nullable) = false
];
}如果中继者（发送者）不是给定基础报价对的授权价格源中继者，或者价格大于10000000，则此消息预期会失败。
MsgRequestBandIBCRates
MsgRequestBandIBCRates 是一条消息，用于即时广播请求到bandchain。// MsgRequestBandIBCRates defines a SDK message for requesting data from BandChain using IBC.message MsgRequestBandIBCRates {
option (gogoproto.equal) = false;
option (gogoproto.goproto_getters) = false;
string sender = 1;
uint64 request_id = 2;
}任何人都可以广播此消息，无需特定授权。处理程序会检查BandIbcEnabled标志是否为true，如果是，则继续发送请求。
MsgRelayPythPrices
MsgRelayPythPrices 是一条消息，用于将Pyth合约的价格中继到oracle模块。
// MsgRelayPythPrices defines a SDK message for updating Pyth prices
message MsgRelayPythPrices {
option (gogoproto.equal) = false;
option (gogoproto.goproto_getters) = false;
string sender = 1;
repeated PriceAttestation price_attestations = 2;
}
message PriceAttestation {
string product_id = 1;
bytes price_id = 2;
int64 price = 3;
uint64 conf = 4;
int32 expo = 5;
int64 ema_price = 6;
uint64 ema_conf = 7;
PythStatus status = 8;
uint32 num_publishers = 9;
uint32 max_num_publishers = 10;
int64 attestation_time = 11;
int64 publish_time = 12;
}
enum PythStatus {
// The price feed is not currently updating for an unknown reason.
Unknown = 0;
// The price feed is updating as expected.
Trading = 1;
// The price feed is not currently updating because trading in the product has been halted.
Halted = 2;
// The price feed is not currently updating because an auction is setting the price.
Auction = 3;
}如果中继者（发送者）与oracle模块参数中定义的Pyth合约地址不匹配，则此消息预期会失败。
MsgRelayStorkPrices
MsgRelayStorkPrices 是一条消息，用于将Stork合约的价格中继到oracle模块。
// MsgRelayStorkPrices defines a SDK message for relaying price message from Stork API.
message MsgRelayStorkPrices {
option (gogoproto.equal) = false;
option (gogoproto.goproto_getters) = false;
option (cosmos.msg.v1.signer) = "sender";
string sender = 1;
repeated AssetPair asset_pairs = 2;
}
message AssetPair {
string asset_id = 1;
repeated SignedPriceOfAssetPair signed_prices = 2;
}
message SignedPriceOfAssetPair {
string publisher_key = 1;
uint64 timestamp = 2;
string price = 3 [
(gogoproto.customtype) = "cosmossdk.io/math.LegacyDec",
(gogoproto.nullable) = false
];
bytes signature = 4;
}如果发生以下情况，则此消息预期会失败：
中继者（发送者）不是授权的oracle发布者，或者
assetId在提供的资产对中不是唯一的对
SignedPriceOfAssetPair的ECDSA签名验证失败时间戳之间的差值超过
MaxStorkTimestampIntervalNano（500毫秒）
MsgRelayProviderPrices
特定提供者的中继者可以使用MsgRelayProviderPrices消息发送价格源数据。
// MsgRelayProviderPrice defines a SDK message for setting a price through the provider oracle.
message MsgRelayProviderPrices {
option (amino.name) = "oracle/MsgRelayProviderPrices";
option (gogoproto.equal) = false;
option (gogoproto.goproto_getters) = false;
option (cosmos.msg.v1.signer) = "sender";
string sender = 1;
string provider = 2;
repeated string symbols = 3;
repeated string prices = 4 [
(gogoproto.customtype) = "cosmossdk.io/math.LegacyDec",
(gogoproto.nullable) = false
];
}如果中继者（发送者）不是给定基础报价对的授权价格源中继者，或者价格大于10000000，则此消息预期会失败。
