Monitors the oracle contract for new data requests(aka "oracle blocks"). As soon as a new challenge is emitted it is sent to the miner module to find a solution.
It simply solves the PoW challenge which is required by the oracle contract when submitting values.
Submits the currently requested data IDs to the oracle contract. It supports submitting to different oracle contracts(see the setup page for more details). It makes all the necessary checks to prepare the data accordingly to avoid failed transactions. The data is taken from the PSR module.
It defines all DATA ids for the oracle contract. For example DATA is 10 in the tellor oracle contract is 24h VWAP of the AMPL/USD price. It uses the aggregator to get the required aggregated data.
Aggregates data to expose median, mean, TWAP, VWAP etc. It uses the data from the local/remote db. The db is populated by the index tracker.

It gets and parses data from an HTTP API or a Blockchain smart contract for later usage or aggregation. Another tracker is the profit tracker. It monitors and records all profit and cost for a one or multiple addresses.
