 There are two types of data providers, ordinary ones and trusted data providers. Trusted data providers are decided by a governance process and do not need to become whitelisted, as they are whitelisted by default. During usual operations of FTSO system, trusted data providers have exactly the same role as ordinary data providers. Only in exceptional situations when FTSO system goes into a special fallback mode these data providers are relied on to provide prices from which average is calculated. Special fallback mode kicks in if too small number of data providers sends their prices (too small in terms of total vote power), or if price changes abruptly, or if it is triggered by governance. In special fallback mode no rewards are distributed to trusted data providers.
 
-All other providers can try to get whitelisted. Whitelisting is a completely decentralized procedure and it is based purely on vote power. It is managed by `VoterWhitelister` contract. Any data provider with `address` can try to whitelist itself for a currency with `index` by calling `VoterWhitelister.requestWhitelistingVoter(address, index)`. If data provider's vote power (= WSGB balance + WSGB delegations) is high enough, it gets whitelisted. For each currency at most 100 whitelisted data providers can exist. A new data provider can get whitelisted only if there are still free empty slots or its vote power is greater than the voting power of some already whitelisted data provider. In this case, the whitelisted data provider with minimal vote power gets removed from the whitelist. This is fully managed by `VoterWhitelister.requestWhitelistingVoter(...)`. At any time, a data provider can try to obtain its whitelisting mask, by calling `PriceSubmitter.voterWhitelistBitmap(address)`. This is a bitmask, where positions of bits correspond to indices of currencies. An index for a supported currency can be obtained on `FtsoRegistry` contract, by calling `FtsoRegistry.getFtsoIndex(symbol)`. Supported symbols list can be obtained by calling `FtsoRegistry.getSupportedSymbols()`.
