I was browsing reddit when I stumbled across a really nice post about all of the issues with scaling Bitcoin. It's well worth the time to read:
https://www.reddit.com/r/Bitcoin/comments/3ybaqj/an_attempt_at_a_fully_comprehensive_look_at_how/Here's one really great point I hadn't thought of. I've thought a lot about lightning, but I never made the connection between the price to publish and it's utility.
Problems with The Lightning Network
The LN works relatively well (in theory) when the cost and time to publish a set of transactions to the network are kept low. Unfortunately, when the cost and time to publish a set of transactions on the blockchain become high, the LN's utility is diminished. The trust you get from a transaction on the LN comes only from the trustless nature of having transactions published to the bitcoin network. What this means is that if a transaction cannot be published on the bitcoin network then the LN transaction is not secured at all. As transactions fees rise on the bitcoin blockchain the LN utility is diminished. Lets take an example:
Cost of publishing a transaction to the bitcoin network = $20
LN transaction between Bob and Alice = $20.
Transaction between Bob and Alice has problem therefore we want to publish it to the blockchain.
Amount of funds left after transaction is published to the blockchain = $20 - $20 = $0.
I can't think this deeply, does it look like the price would get so expensive, in any practical sense?
Also, is it just me, or does it seem more centralized. Somebody posted that the side chain did not require trust and was just as decentralized as Bitcoin's blockchain. Does each sidechain have a POW/POS system? And it looks to me that they're expecting the businesses to foot the bill for the full nodes but why would they, if they could ride on the backs of others, especially if they're small businesses. Anyway, it seems there are so many issues that are so difficult to predict, and the solutions are so inflexible. It really hits home how well thought out, or developed your plan has become, Evan. It kind of grew organically, but the growth was definitely directed with your innate sense of how the puzzle needed to go together.
But i have to say, with the Dash subsidy diminishing, and the cost of transactions remaining free, with businesses paying the fees, I worry that the MN and mining income will drop too much, as the rate of return will drop significantly. I just hope it works out well, so that the subsidy loss will in fact be made up with the fees and usage.
And tok, that's a cute video, wow, 1956! It all looks so small scale and old fashioned. I doubt they do it that slowly anymore! The labor would cost way too much!
