Outdating spam attacks and disregarding their info kills the immutability part of the system. There is currently no solution to this issue as if fee reduces spam becomes more prominent and bloats the blockchain. Their needs to be a balance.
As as the fee goes down, spam of the tangle goes up. Wow man, this is hard problem. Thanks for your words & study. Hope they can get it figured out. Do you think Lightning will have it down pat?
Lightning is a great solution but it is still years away from production use. Ethereum is doing something similar but their tech is also scheduled to be ready in 2019. Nothing is available right now.
Wonderful. Thank you for the information. I look forward to investing into Ethereum if they get it all together. Do you feel like geopolitics will affect the network's latency?
