Block size is protocol's security parameter. Cap on block size is not artificial. Thought experiment: if block size is unlimited, would it affect security? The answer is obviously yes, so it's not artificial.
- erpellan 9y agoSatoshi added the block size cap as a DOS-prevention mechanism (to stop blocks from being bloated with 'dust' txns and grinding the network to a halt). It was done without any real discussion and the value was probably whatever felt right to him at the time. If he'd made it 10Mb, we'd be having this discussion in a few years time rather than now.
- sanxiyn 9y agoYes, I agree it is very reasonable to debate whether limit should be 1 MB or 10 MB or whatever. I don't think it is reasonable to say it should be unlimited, or decided by market, or such.
