Topic: Will the Lightning Network challenge VISA someday? - page 2. (Read 374 times)

That's for the clarity on this. LN is mainly an off-chain bypass methodology which collects multiple payments and broadcast it to the bitcoin blockchain as a single payment.

I know LN is now officially released and we already have LN wallets available in the market. But it indeed has a long way to go before it becomes mainstream. For LN to overcome Visa, Bitcoin has to first position itself there! So even I don't see how bitcoin or LN can even stay at the same position as Visa.

It is like a newbie challenging an industry leader. Don't see it happening in our lifetime!

I'm kinda under doubts tbh. Bitcoin was amazing back when only few were using it. Many coins seem great before they get congested, and then you find out they aren't as strong as they were supposed and presumed to be. I honestly think the LN is no different. At one point, having enough adoption, the mempool will be challenged even with LN widely adopted.

As I mentioned in a recent thread of mine, the problem is with the first layer and not with the second one. Bitcoin will need some changes before it can technically challenge centralized fiat convenience. But let's not forget that technical specs don't always mean similar results.

Listing prices in BTC doesn't change the fact that BTC's value changes rapidly. USD isn't more stable than Bitcoin because it's used for goods and services, it's more stable because it's not speculative, since its fundamentals are much more predictable.


I don't agree that this is just an experiment. LN is already "unoficially" on the mainnet, there are no major obstacles that could make it a failure. Wide adoption of LN in Bitcoin community is a question of time.

So which one is it, it has the capability or it is limited 
That block limit will most likely stay like that for years, I don't see anyone ever challenging it, and not a single of the current dev proposing this so it will all have to come from the capacity of the channels and finding a way to keep the coins spinning around in the network, which brings us the problem with the limited service offered, and so on and on.

But in the end, why does it have to compete on Visa's terms?
I don't think that we will have to soon the number of customers using bitcoin to rival Visa even with the capacity, what Visa has and bitcoin will never have with a 3rd party service is the easy usage for their cards. You swipe your card, payment in seconds, card accepted everywhere, you lose your card you have somebody to call, you have the funds in your linked bank accounts insured, those are things bitcoin will never be able to do.
And a lot if not the decisive majority will appreciate those more than being their won bank like a lot of them don't like this responsibility that comes with it.

Before bitcoin can challenge Visa there are a lot of things that need to change, with one of the most important being how people think and act, and this will take a while, maybe even a decade is an optimistic scenario.

We should probably ask first if Lightning Network will be mass adopted before talking about challenging VISA. How do you expect it to challenge other platforms when the majority of the Bitcoin community do not even support it?

Those who are into altcoins with cheaper fees and fast transaction won't bother spending sats for opening channels.

The main issue is price volatility. This could be attributed towards the lack of regulation and low liquidity on the crypto market (compared to the traditional stock market). Volatility is linked to the price of Bitcoin relative to Fiat. But what if people use Bitcoin as a unit of account? Then, 1 Bitcoin would be equal to 1 Bitcoin no matter what. If we start to value things based solely on Bitcoin, volatility would no longer be an issue. People would just pay any amount in Bitcoin regardless of its current price on the market. Yet, this hasn't happened as the world moves around Fiat these days.

As far as the Lightning Network is concerned, I think it has all of the capabilities of surpassing VISA in terms of TPS. What's limiting the LN to go full speed ahead is the lack of mainstream adoption. Not to mention, the LN is limited to Bitcoin's own transaction capacity. After all, LN channels are opened/closed on the Bitcoin blockchain itself. With a limited block size of 1MB, the LN will not be able to expand towards new heights. The constant opening/closing of LN channels on the Bitcoin blockchain will only make matters worse in the long run because of the block size limitation. Who knows what will happen with Bitcoin in the long run as it becomes more popular in the mainstream world?

Nonetheless, the LN is nothing more than an experiment. Besides years of research and development, the off-chain scaling solution is still in its infancy. It won't be able to overcome VISA if progress remains slow. At least, people have a choice to skip high fees and slow transaction confirmation times on the Bitcoin blockchain. As I've said many times before, people could either choose the Lightning Network or an altcoin to enjoy fast transaction confirmation times and low fees. Time will tell us whenever the LN will be able to challenge VISA as a payment processor or not. Just my thoughts

The "mainstream world" you're referring to, will never adopt the Lightning Network, because they'll never adopt bitcoin generally. The mainstream people are enough with Visa, they don't need anything more. The Lightning Network helps us. The bitcoin adopters. It is here to revive bitcoin as a medium of exchange.

But it can't replace Visa, because besides the "mainstream" argument, Visa provides something LN doesn't. Instant transaction with nearly zero fee for one-time-purchase. If you want to just buy a coffee, it won't benefit you to use LN. You'll have to broadcast two transactions on the blockchain, that's a ton of money on fees. You'll use Visa, because after all, you don't want to make another transaction with the seller.

For what community are you talking about? Once you make a LN transaction, any party can broadcast it at any time as long as the node is online. So even if one of them does not remain cooperative, the other can close the channel and every party will receive the final balance of their signed transactions.

Lightning Network is Bitcoin. For Bitcoin to challenge Visa, a lot of other factors need to be resolved too, not just the scalability. Price volatility is a problem, as unstable money is impractical for business. Bitcoin is not fully recognized by governments and their stance could change at any time. Most importantly, majority of people does not see benefits in using Bitcoin as money - banks work quite well and smooth for most people, on average their user experience is far better than Bitcoin's. Bitcoin's main goal is to let people control their money, but this is not what most people are interested in.

The answer to that question will be highly dependent on the mass adoption that will happen to Bitcoin (if it ever happens). Visa as of 2019 recorded around 185 billion in transactions if we count other card providers like Unionpay and Mastercard you will get 131 billion and 108 billion transactions, respectively. Now I don't have the number for LN related transactions but assuming that it is an equivalent amount in the Blockchain which is 325,000 transactions daily you will get 118.63 million transactions daily which is just a small fraction as compared to number of Visa related transactions. Comparing it to Visa and the other related parties Bitcoin still is a long way of even matching their daily us and I think we all know for it to happen mass adoption is something we need to look at.

VISA has some of the biggest dedicated data centers engaged in all those rapid transactions over a centralized network. While the thought of having LN takeover Visa is tempting, it is really difficult for a network of voluntary, bootstrapped nodes with several bottlenecks to surpass the processing capabilities of dedicated hardware like the ones that companies like VISA employ.

LN by itself should be quite good for those of us who want to use BTC. While its a nice thought experiment, it isn't quite possible for even LN to change the status quo on this one.

To answer this question we must understand how LN works and why the transactions are instant.

To make transactions with Lightning Network the business that want to accept LN payments needs to create some kind of 'channel', so, let's say you have a hosting business and you are accepting Lightning Network, then you create a channel with 0.1btc. So, when a client pay to you the service of 0.002btc now your 'channel' will have 0.098 available for LN. Once the channel gets full then it broadcast a transaction in the bitcoin blockchain to confirm all the LN transactions in one real transaction on the blockchain.

Now you can see the problem with replacing VISA. The transactions are instant but the community needs those channels to spend with LN, so, my answer is a big NO. Lightning Network can't replace visa.

Thanks to the Lightning Network, it's now possible for Bitcoin to provide instant, cheap transfers to everyone. Adoption for the off-chain scaling solution is low, in part because of the LN's complexity. Now, imagine an scenario where the Lightning Network becomes heavily adopted by people in the mainstream world. It could threaten the existence of traditional payment processors as we speak. While I don't know how much TPS the Lightning Network is able to process, I'm pretty sure it's near close as VISA.

Do you think the Lightning Network will be able to challenge VISA someday? If not why? What if traditional payment processors like PayPal, VISA, and Mastercard decide to run a LN node in the future? Will this benefit Bitcoin in the long run or not? Your input will be greatly appreciated.
