The Solana FluxAggregator program is modeled after the FluxAggregator.sol contract in ChainLink.
Data submissions happen rounds. In each round minSubmissions must be achieved to arrive at an answer.
- An oracle must wait restartDelay rounds before being allowed to initialize a round
- restarDelay should default to
oraclesCount/3
- restarDelay should default to
- Oracles should submit a new round when value deviates at least minDeviation
from the latest answer.
- minDeviation should default to 0.1%
- This is not enforced by the smart contract
latestAnswershould return the median, as well as thelatestAnswerResolvedTimetimestamp- A round updates the latest answer when minSubmissions is reached, taking the median
- Each additional answer in the same round below maxSubmissions would recalculate the median, and update the latest answer
- If rounds stop updating (i.e. not enough oracles to reach
minSubmissions), the latest answer is always the last round that had resolved - An oracle cannot submit to the previous round. The transaction will revert, and the oracle should retry
Wont implement:
- Oracle can start a new round only if the round fails to resolve an answer after
roundTimout(while satisfyingrestartDelay)- Reason: restartDelay is sufficient
- An authorized requester can start a new round at any time, limited by
requesterRestartDelay- Reason: just ask oracle do it
- Feedback: Oracles can submit to the previous round if the current round has not reached minSubmissions
- Reason: This would complicate implementation, and doesn't provide much value, since on solana tx are really cheap. Reverted TXs are no big deal.
