Let's talk about the realities of Lightning for a minute. Lightning is an interesting technology solution to scaling transactions and settling on the blockchain. But realize that there are significant drawbacks.
In order to spend anything on the lightning network, you need to have funds locked in a channel with a hub. And you can only spend the maximum that is in your hub. Likewise, you can only receive up to the maximum that the hub has put in the channel. In other words, your net credit or debit balance can't exceed the maximum put in by the other side.
There are some significant user experience drawbacks to this approach. I want to send someone $100, but I only have $50 in my channel. So now I need send $50 more of bitcoin and wait 20 minutes for confirmations. Then I can send the $100. It is even worse if I want to receive $100. Now the hub (bank?) has to approve my request to "receive" $100 because it costs them fees and capital to fund the channel. Make no mistake, the hubs will pass these fees on to you, the consumer.
Suddenly this starts to look a little more like Paypal then we want. Granted it is a better version of Paypal - there can be multiple, interoperable hubs - but with small blocks, funding transactions will not be cheap.
In a small block world, Lightning network fees will likely be more than you think. It could easily cost $10 worth of bitcoin for both sides to fund a $1000 channel. Why would I want to tie up $1000 to use this. I'd rather just pay the 3% to send via Paypal.
- VMG 9y agoWhy should lightning fees be high if there is an open market for hubs and they compete on fees?
- simias 9y agoRunning a hub could end up being expensive as you need a massive amount of "collateral" to lock in your channels. A hub is rather worthless if it only provides $1 channels to all its "subordinates". If you have a huge "bank of america" hub connecting to hundred of thousands of entities through large channels on one side and a small "mylightninghub.io" with a dozen of people through $10 channels you better hope that they're extremely competitive on fees to make up for it. It's almost exactly like the credit card business currently. If I come to you and tell you "Here's the SimiasCard, it has extremely low fees and great advantages! But you're limited to $5 a day and it's basically accepted nowhere." Would you take it?
