And the cost of bearing this load must be paid for. And unless we’re willing to accept that computational resources are finite and subject to the same economic issues as any other finite resource, our incentive model collapses the security of the network will be significantly at risk.

The block size isn’t about scaling but about supply and demand of finite resources. As demand for block space increases, we can address it either by increasing computational resources (block size) or by increasing fees. But to do the former we need a way to offset the increase in cost by making sure that those who contribute said resources have incentive to do so.</div></body></html>
