How does Monero propose to resolve the fact that it's blockchain is growing faster than Moores Law and pruning is so limited?
Human populations don't grow faster than Moore's law. Duh.
Disk arrays scale to anything we can fathom.
The issue is that no block chain consensus can maintain decentralization of validation, not because of scaling problems but because of the fundamental economic reality that not every miner can have an equal share of the hashrate, thus verification costs are not shared equally. The creates an asymmetry where economies-of-scale will maximize profit and grow hashrate the fastest thus centralizing mining.
The solution requires some clever innovation on proof-of-work.
