The “big block” project that itself forked away from the Bitcoin blockchain in August 2017 fragmented into “Bitcoin Cash ABC” (BCHABC) and “Bitcoin Cash SV” (BCHSV).In this third and final overview: the main takeaways and latest developments of the second week since the Bitcoin Cash split.Hash War OverThe Bitcoin Cash split drew as much attention as it did in part because Bitcoin SV proponents had announced a “hash war.” Where previous “coin splits” were relatively peaceful — both sides of the respective disputes went their own way — nChain chief scientist and Bitcoin SV frontman Craig Steven Wright threatened that miners would 51% attack a potential Bitcoin Cash ABC chain out of existence.But as the coin forked and the world watched, nothing irregular happened. Possibly because Bitcoin Cash proponents brought in additional hash power to secure their side of the chain, no 51% attack took place.One day after the split, Wright said Bitcoin Cash SV miners would instead maintain an “endurance attack.” If and when more miners left the Bitcoin Cash ABC network, the 51% attack(s) would commence. For well over a week, both chains did attract more hash power than their respective block rewards warranted, suggesting that miners were losing millions of dollars in a se...
