Let's see an actual LN in operation and how it operates it before deciding anything. Much has been theorised. Nothing has been proven.
that's my take. and it goes both ways; we can't hold the lightning network up to be the answer to all scalability questions, because we haven't seen it work in practice. some tests, sure, but nothing on mainnet, and nothing at the scale that we need to make it useful for bitcoin.
i'm not concerned about centralization and hub-and-spoke as long as the trust model is secure, and there is no custodial trust involved. as far as i can tell, there isn't, so i fully support LN. how much value it will provide remains to be seen.
Concurred.
There will be bigger and smaller nodes in the network, which is no different to any network where the participants can choose the amount of resources they use in order to participate, this happens with both the Bitcoin network, the cell phone network or the internet itself. Lightning node operators will necessarily need more resources than Bitcoin network participants do, but those resources are..... some BTC. And everyone on the Bitcoin network probably has some BTC anyway, it's just a common sense reason to use the Bitcoin network, not a requirement. So the on-chain "scaling" proponents can exhort us all to join them crying themselves to sleep like this if they want to, but it just is what it is, sorry gentlemen.
Lightning is not the complete answer to the scalability problem, but it sure as hell has huge potential to be either one technology in line-up of scaling solutions, or a stepping stone to whatever scaling tech predominates in the end (and it will very likely be a 2nd layer network, leveraging the combination of high security and user led consensus that the blockchain gives us the way the current balance of incentives is structured on the Bitcoin network). The only route that's not going anywhere much is the so-called "on-chain scaling" ideas. Sure, we can aggregate signatures and other such tricks to encode blockchain transactions more efficiently, but it's never going to create the magnitude of transaction increases needed to allow Bitcoin to fully compete against the euro, dollar or yuan.
