Lightning Network - With 2020 Behind Us, What Progress Was Made Over The Last Year?

Bitcoin Lightening Network

It's the tech that will change everything, says those working to make it a reality.

There's no debate - Bitcoin, as is, cannot function as a viable global currency and you won't hear anyone saying it can.  It's impossible to advocate the idea that someone could seriously buy a cup of coffee with Bitcoin and wait around for 10 minutes waiting for the transaction to complete.

Lightening network would turn that transaction into something measured in milliseconds, not minutes.

Once (or if) it's perfected, it'll have the Bitcoin network powerful and fast enough to rival the tech the economy currently runs on, the infrastructure build by major banks and credit card companies.

However - all with fees so low, businesses and people would probably actually use it.  A popular restaurant could easily give up $2000/month in credit card fees, a solution that would allow them to keep $1900 of that is going to be worth trying out.

With almost three years of development in tow, the Lightning Network is one of the most successful Bitcoin community projects as far as participation.

The payments network has reported year after year a constant growth and great support from users, but in particular for 2020 some of the most outstanding technological advances were registered for the massive use and maturation of the Lightning network.

The network ended 2020 with with more than 15,000 public nodes, most located in North America - more than doubling the previous year.

Along with this came support from some of crypto's well known companies like NiceHash, Kraken, Electrum, and others.

But It Isn't All Good News...

And to expect something in development to be nothing but smooth sailing isn't realistic. But the 2020 bumps in the road include discovering some vulnerabilities in Lightning's contracts sparking debate in the community, with developers and users concerned about both privacy and security.

As mentioned, the number of nodes is growing yet there's surprising lack of decentralization.

Initially the logical design of having nodes look for shorter (therefore cheaper) routes made sense, but this has created a situation where 80% of transactions are completed using only 10% of the network.  Bringing some valid criticism from decentralization advocates..

However, supporters of the current structure point out that transactions are currently coming from users in the same geographical locations as the nodes.  Heavy global usage once the network goes live will solve this issue automatically.

Taking The Network Back From China...

The number of current Bitcoin miners in China is a point of concern for many.  Some simply dislike the ideological clash of the independent nature of crypto, free from governments and banks, being mined in a nation whos government prides itself on strict control of it's citizens and businesses.

Others take things further, citing that China could damage rival economies with a simple order for miners to pull the plug.

But in the case of nodes on the Lightning network, most are located in North America. 45% located in the United States. Europe, on the other hand, concentrates 43% of the remaining nodes and Latin America only 0.8%.

But overall 2020 was a productive year, and Lightning took some big steps forward...

Solutions for some earlier known vulnerabilities were addressed, like the 'timing attack' that left some users private info exposed, and concerns that the network was open to 'channel congestion' attacks.

Lightning Labs improved transaction efficiency with the development of 'Loop' - they impressed enough people to bring in $10 million in financing. They followed this with ' 'AutoLoop' which automated liquidity management.

Decentralized finance (DeFi) found it's way to Lightning, where it's called 'LiFi' instead.

Wumbo was another noteworthy implementation, as it removed the initial limit of bitcoins that could be routed. 

Initially, a limit of 0.1677 BTC was put in place since the network was officially only to be used for testing - this limit removed is a sign that there have not been any major problems.

Now, capacity of channels has been increased to between 5 and 10 BTC.

So - where does this put us as we begin 2021?

The honest answer - much closer to launching, but also, nowhere near launching,

Look at the current price of Bitcoin if you need a reminder of why Lightning will need to be flawless before going public.

Bitcoin's transaction fee nightmare is over (for now). Down from a high of $34 - to $0.78 cents today!

It was nothing short of a nightmare - transaction costs upwards of $30 mixed with insanely slow transaction times, making Bitcoin impractical to use as a method of transferring funds.

The issues caused massive divide within Bitcoin communities - sparking the "store of value" debate, which had many saying Bitcoin was now like gold - not to be used in everyday transactions, but rather a place to store funds - a debate that sparked the birth of the controversial Bitcoin Cash.

But now, those fees are dropping, and fast.

Bitcoin fees lowest they've been since October 2017.
Why the drop? Reasons are mixed. There are less transactions overall from it's peak, but largely there has been some efficiency changes as well. A previously rarely used feature of Bitcoin was the ability to send BTC to multiple recipients packaged into 1 transaction.  When fees were low, the feature was rarely used, but it's being used much more today.

However - as Bitcoin's price continues to rebound, it's expected that transaction volume will as well, especially with low fees back in play - which could just bog down the network again, and send transaction costs right back up.

Solutions? SegWit2x increasing the block size, and lightening network are both on the table and gaining support.

The challenge? Implementation. Even after an agreement on a solution is reached, technical analysts believe SegWit2x could take months to be fully adopted.  Lightening Network - even longer, perhaps years due to the drastic complete overhaul in transaction protocol.

Bitcoin has a major problem, and we can't ignore it any longer...

The Bitcoin network is overwhelmed and there's no way to downplay it - we have a problem.

At time of publishing, there were over 80,000 transactions yet to be confirmed - and earlier, that number was over 130,000.

There goes the idea of Bitcoin (as it is today) replacing cash.  No business is going to wait possibly hours between making a sale, and receiving the payment.

Everyone needs to accept this reality.

So, let's talk solutions.

Bitcoin's block size is 1MB, so maybe picture a pipe 1-inch wide, and each transaction is a quart of water.

Currently, the pipe is too small for the amount of transactions that need to flow through it.

This was the idea behind SegWit2x that was proposed, then canceled last week, which would have doubled the block size to 2MB and in theory double the speed of the network.  However, developers and the bitcoin community couldn't reach consensus on implementing it. It wouldn't be enough to be considered a true solution to this situation anyway. So, scratch that.

Now, Bitcoin Cash is trying to jump into the middle of the crisis, boasting an 8MB block size, but hitting the same problem SegWit2x did - not everyone's on board.

That brings us to what may be the best, and only viable solution on the table - the lightening network!

It sounds cool, and it is cool - because it could mean INSTANTLY verified transactions.

How? By removing the biggest step from the middle of the transaction.

First, the transaction is purely peer to peer, with the transaction occurring on a "private channel" - then only after the transaction is complete, would the final results be sent to the blockchain to be recorded.

Using the same amount of data available on the network now, much more efficiently!

It looks like that's where all this is heading.  Lighting Network technology is currently being tested on the Litecoin network, and they have completed successful test transactions.

Litecoin founder Charlie Lee outlined his "Vision for Lightning Networks On Litecoin And Bitcoin" here.

The next few weeks will be vital, and could determine how Bitcoin transactions will work far into the future!
