The lightning network could be a second-layer innovation connected to Bitcoin, which employs micropayment chains to make strides in the capacity to perform exchanges. Transactions in lightning systems are quicker, cheaper, and easier to validate than those carried out directly on the bitcoin blockchain (i.e., on-chain).

The lightning network built into the decongestion of the bitcoin blockchain  reduces related fees by removing transactions from the main blockchain and turning them off-chain. The lightning network can moreover be utilized for other exchanges including trades between cryptocurrencies. 

For example, it is useful to make it easier for atomic swaps that allow for the swaps of one cryptocurrency on the other without intermediary intervention, for example, the exchange of cryptocurrency. 

Lightning Network understanding
Joseph Poon and Thaddeus Dryja first proposed the lightning network in 2015 and have been in progress since then. The issue that was created to solve the lighting network is the slow transaction period and the bitcoin output. 

To achieve its potential to become a regular transaction medium, Bitcoin would need several hundred or tens of thousands of transactions per second, similar to the credit card or electronic payment networks. Because of the essence of its decentralized technology, which needs consensus from all of its network’s nodes, Bitcoin has such problems in its current state.

The lightning network has suggested solving the scaling issue by adding a second layer on the main blockchain. This second layer includes various channels of payment from parties or bitcoin users. A lightning network channel could be a two-party exchange framework. The parties can pay or receive each other’s payments using channels.

These exchanges are prepared in an unexpected way than normal exchanges in blockchain Bitcoin. Only when two parties open and close a Channel will the major blockchain be changed.

This method greatly accelerates the pace of a transaction since not all transactions must be accepted by all nodes inside a blockchain. Individual payment channels between different parties are combined to form an illumination network capable of conducting transactions. The Lightning Network is the resulting link between different payment channels.

How the flash network works Alice opens a channel and deposits 100$ worth of bitcoin into the channel with her favorite coffee shop. Her coffee shop transactions are instant since she has a direct channel.

The lighting system uses intelligent contracts and multi-signature scripts to achieve its vision more technologically. When one or both parties finances a channel, an original transaction, the financing transaction, is made. The exchange makes it easier to access and spend money.

This is done to avoid the key blockchain recognizing the expenses of financing transactions. Both parties instead share a single key to verify expenses transactions between themselves (also referred to as engagement transactions).

Both parties will make infinite commitment transactions on a lightning network between themselves and other nodes. They just swap their master keys when the channel is closed between them.

Does the Lightning Network have fees to use?
Yes, the use of lightning networks involves transaction fees. It consists of a mixture of routing fees for routing payment details to open and close channels, between lightning nodes and bitcoin transaction fees.

What are some Lightning Network issues?
The main issue with the decentralized lightning networks is that they will contribute to the reproduction of the hub and speaking model that characterizes financial structures in the current period. The key intermediaries for all transactions are banking and financial institutions in the current model.

With more transparent connections with other companies, lightning nodes may become similar hubs or central nodes in the network in prominent businesses. If such a hub fails, a large part (or whole) of the network will easily crash.

The need to raise charges to make maintenance of the network economically feasible is another important issue, as discussed previously. This is not only for the lightning network nodes themselves but also for the knock-on costs of the possibly higher bitcoin fees transferred to the network.

Blitz networks are often thought to be vulnerable to hacking and robberies because they must always be online. The cold storage of coins is not a choice as it is not permitted across the network.

Summary 
Even though many still consider it to be in beta, the Lightning Network has grown significantly since its mainnet launch in 2018.

There are some barriers to accessibility yet to be solved since a Lightning node requires a certain degree of technical skills.

The Lightning Network may be an important part of the Bitcoin ecosystem to address problems and significantly enhance scalability and speed of transaction.
