Miners already have the strongest incentive to validate every input, because an invalid block gets nuked by any honest competitor and the subsidy+fees evaporate. With big blocks, the cost of being wrong goes up, not down: you’ve just spent more CPU, more bandwidth, and risked far larger fee revenue only to have it rejected. Bigger blocks raise the penalty for sloppiness or malice.

@ProjectBabbage This is precisely why unrestricted block sizes are so important: they not only prove a miner's integrity but are also the key to achieving a high-throughput global blockchain.

@ProjectBabbage While segwit promotes laziness and the potential of a "nightmare scenario": gnusha.org/pi/bitcoindev/…

@ProjectBabbage Being compelled to cooperate and compete at the same time without needing to bend the knee or ask for permission. It doesn't get better than that. It's better than capitalism. It's something new and completely different.

@ProjectBabbage Gigameg blocks just make it easier for miners to collude and cheat. A majority of miners (or even all of them) can create txs out of thin air, spend them amongst themselves, then dump them on users or exchanges and nobody can prove their misdeeds.
