Moma Feed Price

1.Committee Feeding Price Mechanism

The ability to set asset prices is entrusted to a committee that centralizes the prices of several exchanges and completes chain feeding price by “Whistle blowers”. These exchange rates are used to determine borrowing capacity,collateral requirements, and all functions that need to calculate the valuation of the account.

The operating mechanism is as follows:

1) Aggregate prices are calculated through price aggregation contracts:

First, several designated exchanges upload the sub-chain price to the price aggregation contract of the specified subject matter in each round. The contract calculates the price average and standard deviation of the same underlying asset provided by several exchanges:

● If the standard deviation is not greater than the preset tolerance threshold, the price average is taken as the credible price to be confirmed in the round.

● If the standard deviation is greater than the preset tolerance threshold, the trusted price to be confirmed in the round is empty.

2) Whistleblower" circulates prices to be confirm credibility in each round. If the price is accurate, it then will be confirmed as the final price. If it is empty, then the early warning mechanism will be initiated, and the manual intervention will be used to check the reason.

2.Decentralized Feeding Price Mechanism

Moma will integrate Chainlink Ooracle and launch its own decentralized price Oracle solution in the future.

Moma Decentralized Oracle Solutions are conceived as follows:

Custom reputation system: Moma will give each Pool full autonomy, and each Pool can choose to establish its own prophecy feeding price market. Supported custom dimensions are as follows:

● Act as a threshold for the price feeders

● Introduction of custom-made reward and punishment mechanism

● Set up of price update cycle

● Custom price audit mechanism
