Implement a loop for getting confirmation and discard or persist the block to the blockchain.

[atif-konasl]

Overview

Need to implement a loop for calling confirmation api every certain interval and process the pending blocks and synchronise with blockchain flow.

Responsibilities

1. It will call a method of client package and get the response of confirmation for certain block hashes and slots.
2. After getting response, If it gets unknown response for certain slot then it will discard the block from pending queue and send request to its peer for these discarded blocks again.
3. If it gets verified response for certain slot, then it will pass this block to blockchain's existing flow for persisting the block into its blockchain
4. This feature must make sure that it will pass the verified blocks sequentially like if slot n is verified but slot n-1 is not verified yet then it will must re-download the block of slot n-1 and then it will process slot n.
5. These step-1, 2, 3 and 4 happens repeatedly every certain period of interval
