Data Feed Reporter Bottleneck

[martinkersner]

Orakl Network Data Feed Reporter is supposed to handle multiple data feeds at once. Submissions to data feeds can come at the same or similar times, and it takes a while before the requests are processed (transaction receipt received). Aggregator smart contract is sensitive to delays, therefore we have to eliminate dependency between various data feeds.

Current State

• we are waiting for transaction receipt from JSON-RPC API
• it can take up to 5 seconds to receive transaction receipt
• ethers.js automatically assigns nonce to transactions
• there are no two transactions processed at once

Future State

• waiting for transaction receipt should not affect (slow down) other data feeds

Possible Solutions

• Unique reporter address for each data feed (hard to manage, easy to scale)
• Handle nonce by ourselves (easy to manage, hard to scale)

We decided to go with the first solution. Implemented at https://github.com/Bisonai/orakl/pull/442
