What happens when the Internet reconnects? Do we throw out half of the transactions? Or is a merge possible? Can it be done automatically? Given how little bandwidth it takes to synchronize blocks, and the enormous financial incentives to solve this problem, it's unlikely that an internet split would result in a long term network partition. It's just too easy to fix the split through technologies like satellite internet, amateur radio, Blockstream satellite, pigeons, etc. If the event leading to the split manages to defeat all these mechanisms on a large scale, there's a good chance that Bitcoin is the least of our worries... Anyway, transactions in blocks that have been reorged out can be mined in subsequent blocks so long as there are no conflicts. In practice, this will happen automatically. -- https://petertodd.org 'peter'[:-1]@petertodd.org -- You received this message because you are subscribed to the Google Groups "Bitcoin Development Mailing List" group.
