This PR is the first step towards reducing reorgs and is a part of RFC35.
It adds a new background service called checkpoint whitelist which keeps running and asks it's heimdall for the latest checkpoint entries. Similar to the
--whitelistflag, it stores the<block number> -> <block hash>mapping. The interesting part is that it leverages the heimdall checkpoints for making these entries. Basically it adds every end block number to end block hash entry to this in memory map (which is capped to 10).This is to prevent the node to connect to wrong/invalid peers which are not on the correct fork. We decide that before even asking the peer for new blocks i.e. in the
findAncestorfunction in downloader. Basically, we ask for the last checkpointed block of ours from the peer. If we're able to validate the details, then and then only we'll allow that peer to connect. In case of mismatch, we will eventually drop or stall the peer until it has relevant and correct blocks.Sufficient unit tests are added and devnet testing has been carried on for the same. The next step is to make modifications in the forkchoice rule. Refer #425 for the next step.
