So, for this protocol, as long as people agree on a genesis block number and a set of consensus rules, the bitcoin blockchain is just used as a timestamping system for all transactions submitted? Is there anything else besides these 3 things that glue the trust in the system together? What else could cause a chain split in the spaces protocol?
