BlockNumberofTx give us how many transactions a block has.

BlockTx is useful to find out whether we have all the transactions of a block, so we can prepare their representation as trie elements.

EthData is the data retrieved from the devp2p clients we try to keep for the longest time possible our data in here, to give the chance to agents to add it into several libp2p availabilities, however in the future we may want to prune this table.

LastBlock tracks the canonical chain.

Options keep db conn parameters.

TxReceipt maps transactions against their receipts.

WantFromDevp2p is the least of wanted data for our agents to retrieve from different devp2p clients.
