> The main bottleneck for cryptocurrencies is that every single node has to validate every single transaction. So your global throughput is effectively limited to what a single node can process literally what I said in my post. the mining aspect was your addition, not mine. I am describing an idealized model which doesn't even consider the added complication of mining to incentivise playing by the rules(let's assume coins are issued based on signs from, say, zeus). just simple consensus on a single 0/1 truth value. this is the hard scalability problem, and people claiming to fix it are ultimately bound to create hierarchies of truth authority, undermining decentralization and recreating the existing concentric power structure (with themselves in the center) they claim to obsolete.
