I believe a hub and spoke model for the Lightning Network would be a better set up in the beginning if the real intention was to "scale" Bitcoin. I don't mind it to be semi-centralized to be quite honest.
there will always be people who are going to run a node whether it is a bitcoin full node or a lightning node on top of it and other people who are going to use lightweight clients that use their full nodes.
just like now that there are a lot of users using Electrum than there are users running an Electrum Node.
I don't think we can call this centralization.
True, but it would be near impossible for the Bitcoin network to reach 100,000 nodes running 24/7. Plus do you know how hard it is to sync a node these days? There is a reason why users prefer light or online wallets.
Storage may not be a problem to some of you but bandwidth is for most of us.
It's not impossible, specially if the blockchain stays at an affordable growth rate of 1MB blocks, the hardware will always be affordable to keep the entire blockchain. As the price grows, the incentives to have more nodes will be there, since without a decentralized array of nodes the network is completely useless as it becomes weak.
Also true, it is not impossible but something that is more likely not to happen. How many nodes are running in the Bitcoin network today? I believe it is under 10,000 nodes? Plus are they increasing or decreasing?
It will not be necessary to run a node to use Lightning, you mean? That is also true and it will give it a little more of a hub and spoke model which is more efficient in my opinion.
The number of LN nodes keep rising, we are past 1700 now, I predict we will get to 2000 during this month at this rate, and like I said, you require a full node thus far to run a LN node. In the future this will not be the case, like I said, probably with some sort of compromise which I assume will be reasonable for the task (LN is not supposed to be used for big amount).
Yes but to run a Lightning node, you have to run bitcoind and sync the blockchain. I believe we have fewer than 100,000 people who want to run a fully synced bitcoind for free, 24/7 just to run a Lightning node.
I believe we will have "Lightning services" in that will not require us to run a node in the future.
