Which is a huge problem. Concretely, what O(n^2) scaling means is that the more Bitcoin is adopted, the harder it is to use in a decentralized way that doesn't trust others; the blocksize limit puts a cap on how centralized Bitcoin can get in a given technological landscape. -- 'peter'[:-1]@petertodd.org 0000000000000000007fc13ce02072d9cb2a6d51fae41fefcde7b3b283803d24
