Medianizer
Oracle component that fetches the price of an asset
There are five types of medianizers that can be used in GEB:
  1. 1.
    DSValue - used when deploying the system on a localchain or a testnet in order to easily manipulate the price feed of a collateral type / system coin.
  2. 2.
    GovernanceLedPriceFeedMedianizer- offers more security by requiring a quorum of oracles to submit their prices which are then medianized on-chain.
  3. 3.
    ChainlinkPriceFeedMedianizer - relies on a Chainlink aggregator in order to fetch and push price feeds in to the system.
  4. 4.
    UniswapConsecutiveSlotsPriceFeedMedianizer - computes the average price for an asset in the last m seconds and can be connected to a GovernanceLedPriceFeedMedianizeror ChainlinkPriceFeed medianizer in order to translate the asset's price (e.g use the WETH/WBTC pool to get the price of WBTC in terms of WETH) in a different currency (e.g translate the WBTC/WETH Uniswap pool price into USD).
