brewchain's Issues

New blocks to be added are verified on both the Node level and Chain level instead of only one

The index and previousHash are verified on the Node level for a new potential block in the processedRecievedBlock() function within brewNode. Then, if these values are approved, they end up being checked once again when the node calls the BrewChain function addToChain().

What is the reason for checking the index and previousHash of a new block twice before adding it?

Also, when adding a whole chain rather than a single block, these values are only verified once on the chain level, and not at all on the node level.
