https://twitter.com/MarkFriedenbach/status/1030211193544134658I will be giving a talk at #ScalingBitcoin on how a block size increase up to 3600x the present size and a change of proof-of-work can be achieved with a fully backwards compatible soft-forkold clients see all transactions and valid SHA256 block headers. This is not good news if onchain. I hope this is a sidechain solution.
As I understand it, Mark is
not proposing that any of these changes actually be made - he is just going to do a presentation that he says demonstrates that it is theoretically possible to do basically any change as a soft fork.
