Well, they say that "anyone can use" a 2nd layer lightning network but realistically nobody is going to trust any basement-dweller to intermediate their off-chain transaction. This will centralize off-chain scaling to large players like Blockstream.

Blockstream will run a Lightning hub and make money off of facilitating transactions before settling them on-chain. Since blockspace is limited they will make (or have made) agreements with miners like BTCC in China - that way they will always be able to settle, but on-chain transactions might get kicked off and be forced to use their centralized system. It's really rather insidious.

Lightning is also not the peer-to-peer solution that the Bitcoin Whitepaper promotes in its abstract. The first few sentences describing the reason for Bitcoin to exist in the first place make peer-to-peer the number one priority.

Why do you think Blockstream would capture a large part of that market? They are only known by people who care specifically about the implementation of bitcoin. If you did a survey of just users I doubt more than 50% would know them. Their are much more well known entities in the space that are far more likely to win a battle to be primary hubs.

Bitcoin can't scale in a peer to peer way to handle any real kind of volume. It's kind of the downside of distributed systems is that they suck at scaling and throughput.

I'm guessing you want them to increase the block size to 2mb but what does that get you? 6tps? So we go to 20mb and you're up to 60tps? You can't scale it on chain and get anywhere near the tps needed for it to be globally successful.

So your options are offchain scaling or limiting its uses with fees.

Our implementation will not be biased towards Blockstream's hub if they ever make one. In fact, it's designed to work in a scale-free network topology.

What the heck Joseph, when you first started talking about lightning I spent considerable effort trying to convince you that "hub" was a bad model for thinking about or describing these things.

Blockstream has no intention of ever monetizing lightning on Bitcoin in any way (nor do I have any idea how we could do so); our interests for it in the case of Bitcoin are only to promote and expand the use of Bitcoin. (We also hope to use it to enable other kinds of asset systems).

Sorry Greg! I didn't mean it in the sense that Blockstream is planning for a hub at all! I was being sarcastic, but perhaps that wasn't conveyed properly in text. I thought the "if they ever make one" was sufficient, but it didn't properly convey the cultural apprehension towards those types of systems and could be seen as deeply disrespectful. We were definitely in agreement from the start that decentralization in the protocol layer was immensely important.

I thought it was obvious that the parent poster was being ridiculous, but should've ended the post with :^)

No problem! Understood. It's a bit tough with so much crap being flung to stay clear of it. :)

nullc,

I'll take your word for it that Blockstream will never run a Lightning network hub.

We understand how the Lightning network works and you also have to admit that it has the potential to centralize into a few large hubs -- even if they aren't by Blockstream -- that will be able to provide the lowest transaction costs in order to keep track of user transaction data.

The problem with Lightning is that it's really far off, and it might not even work.

Meanwhile the network is breaking at the edges while we wait for this pie-in-the-sky solution. Increasing the blocksize is the best approach and it's safe to do as a hard-fork. The delay and push back from CoreDevs is what makes people not trust you. We've had enough "my transaction didn't confirm" posts.
