You touched on something that I have been trying to work out but don't nearly have the expertise to create. Bitcoin requires PoW because it's implemented as back-pointers, where the global software states that everyone coalesces behind the tallest chain. But why not just implement a linked list, where the next link is written into the current block, and whomever writes to that next block wins? You would end up with endless blocks, but we can use what we learned with ext2 fs, where we have a circular queue. Once the data has been consumed by the main datastore, it is consumed and is available to be written to again. You can still store the entire chain in some cheap s3, and anyone who wants to ensure that every command was executed could do so, but most would not. I would love to see this implemented with torrent technology, such that I could host a website database solely by paying a seedbox company.
