Consensus perhaps need not be confined only over tx into blocks,
could be extended over other data and knowledge into blocks,
such as of hashes over utxo set computed at checkpoints.
Could utilize already trusted consensus mechanism (10 years
and billions current value) to make skipping genesis validation
possible... perhaps even tx stream feeding diffs to database
consensus.

Alternatively, how do you know you have a valid
genesis block and network view? PKI? MITM?
Equivalent lols.
