On the Bitcoin blockchain, Lightning Network future of bitcoin.it is a layer-2 solution. Scalability of blockchains is mostly dependent on layer-2 solutions. The importance of the Lightning Network among layer-2 solutions proposed attributed to its connection.Bitcoin (BTC)its capacity to enhance chain utility value.
As a peer-to-peer electronic payment mechanism, Bitcoin was intended and developed. Users might now transfer value without the necessity of a middleman as a result. The Bitcoin creator’s primarily focused on these two features at the time of its creation.They ignoring scalability and transaction throughput.
Although initially this wasn’t a big deal, as the years went on it became more of a problem.Blockchain architects had to strike the correct balance between decentralization, scalability, and security in what was known as the “blockchain trilemma.”people say’s Lightning Network future of bitcoin
Decentralization concept in Blockchain:
The most decentralized blockchain in existence today, Bitcoin is also regarded as being highly safe. Scalability, though, has been a problem for Bitcoin-based transactions. On the Bitcoin network, transactions can finish in two minutes or several hours.
Due to the emergence of new blockchains with higher transaction throughput. like Ethereum and Solana, this problem has become increasingly serious. Bitcoin only processes five transactions per second, whereas Ethereum processes 30. With up to 65,000 TPS, Solana raises the bar for comparison.
Blockchains like Bitcoin and Ethereum have no choice. They rely on layer-2 solutions as a result of the emergence of scalable blockchains. Additionally essential for chains that want to have a strong application environment are higher transaction throughput. Frictions like slow transactions and excessive transaction costs can quickly ruin the user experience on decentralized financial (DeFi) applications.
The Lightning Network, which offers four crucial features and is the most significant layer-2 network in terms of Bitcoin, will be discussed in this article.
Evolution of the Lightning Network?
It is crucial to understand the Lightning Network’s beginnings and development into what it is now. To address one of the most serious problems and frequently raised concerns within system. the Bitcoin ecosystem—the rise in transaction fees—Joseph Poon and Tadge Dryja teamed up in February 2015.
The unconventional partnership started focusing on lowering the transaction fees.After taking a hint from Satoshi Nakamoto’s writings on payment methods. After a thorough white paper on the Lightning Network was released in January 2016.Other developers began working with the founders to advance the project.
Lightning Labs, the organization responsible for maintaining the Lightning Network.issued a beta version for developers to test a few years after the white paper and developer collaboration. The plans of Lightning Labs and the value the layer-2 solution can offer to the larger ecosystem.This system began to catch the attention of influential figures in the tech sector as a result.
Emerging Light Network:
The former CEO of Twitter, Jack Dorsey, was one of the well-known figures that backed Lightning Labs in their aspirations to merge Twitter with the Lightning Network. A significant year for the Lightning Labs team was 2020, the year of the COVID-19 pandemic, which saw the release of notable features including Keysend and Wumbo Channel. The important release known as Wumbo raised the maximum transaction size supported by the Lightning Network.
The Lightning ecosystem now offers a wide range of goods, initiatives, programs, and experiments that span industries and functionalities. such as games, wallets and payments, node management, infrastructure, and rewards. The following are a few notable Lightning Network-based features and products:
- Loop: Loop enables users to send on-chain Bitcoin directly into a Lightning channel or make a Lightning transaction to an on-chain Bitcoin address.
- Pool: Pool aids in managing the user’s liquidity requirements on the Lightning Network.
- Taro: Taro helps the Lightning Network mint or issue assets.
- Faraday: This data analytics solution aids node operators in streamlining channels and money movement.
This ecosystem is becoming into one of the most robust ones in the cryptocurrency world as new projects are being established and a number of well-known figures support Bitcoin and Lightning Network.
How does the Lightning Network work?
As briefly mentioned above, Satoshi Nakamoto’s concept of payment channels is used by the Lightning Network. A peer-to-peer payment channel can be established between two parties thanks to the protocol.
Once formed, the channel enables the parties to send an endless number of cheap, practically instantaneous transactions. Users can use it as their own private ledger to pay for even smaller products and services, like coffee, without harming the Bitcoin network.
A particular quantity of Bitcoin must be locked onto the network by the payer in order to form a payment channel. Once the Bitcoin is locked in, the recipient is free to invoice any amount they like.
Both parties can exchange money by means of a Lightning Network channel. Some transactions are treated differently on the Bitcoin blockchain than regular transactions. For instance, the main blockchain is the only place where two parties are updated when a channel is opened and closed.
Without alerting the main blockchain, the two parties are free to transfer money between them forever. The layer-2 protocol significantly speeds up transactions because none of them must be approved by all nodes.
Individual payment channels between the parties involved are combined to create Lightning Network nodes, which can route transactions. As a result of several payment channels being connected, the Lightning Network was created.
The channel can eventually be closed once the two parties have concluded their transaction. The channel’s transactions are then combined into a single transaction. This transmitted to the Bitcoin main net for storage. In order to prevent the network from becoming overloaded, tiny transactions are combined.
It takes nodes less time and effort to validate a transaction when they are combined into one. Without payment channels, smaller transactions obstruct larger ones, clogging the network and adding to the strain of nodes involved in validating transactions.
For instance, Mike might decide to make a tiny transaction for each coffee cup he purchases at his neighborhood coffee shop. However, because of scalability concerns with Bitcoin, the transaction may take more than an hour to validate. Even though Mike is only performing a little transaction, the Bitcoin network charges significant fees.
Because firms like Visa have the infrastructure to process more than 24,000 TPS, small transactions can be processed using conventional payment methods like a card. On a typical day, Bitcoin can validate seven transactions per second.
Mike can set up a payment channel with the coffee business over the Lightning Network. Within that channel, each coffee purchase is tracked, and the business is still compensated. The transaction is instantaneous, inexpensive, or even free. When Mike’s first Bitcoin investment in the channel runs out, he has the option of closing it or adding more. All of the transactions that took place on a channel after it was closed were then added to the main Bitcoin network.
Contract for Transaction:
A smart contract is established between two parties using the Lightning Network. The contract’s terms are hard-coded into it at inception and cannot be changed. Due to the fact that contracts are initially formed with predetermined conditions that are accepted by all parties, the smart contract’s code also guarantees that contract fulfillment is automatic.
The contract is immediately fulfilled without the intervention of a third party whenever those conditions are satisfied and when a consumer pays the appropriate price for a coffee. Once a transaction has been verified, the Lightning Network future of bitcoin anonymizes it within a payment channel. No one can see the particular transactions within.it is just the overall movement of value.
Outside of the blockchain, transactions can be carried out without any constraints. Given that off-chain transactions eventually show up on the main net when payment channels are closed, they may be relied upon to enforce the blockchain. All transactions are decided by the main net. Off-chain protocols have their own ledgers, but the essential feature of the Lightning Network’s design is that each ledger always integrates back into the main chain.
Tangible advantages of the Lightning Network
On its official website, the Lightning Network describes itself as the “leading technological development in multiparty financial computations with Bitcoin.” The following benefits are offered by the Lightning Network over the original Bitcoin blockchain.
Low energy needs, speed, scalability, and support for micropayments.
One of the elements of the Bitcoin blockchain that has received the most attention is its inability to scale. The network’s growth was significantly limited by the insertion of each block for each transaction. This is resolved by the Lightning Network by removing the transactions from the blockchain while taking security and anonymity into account.
Speed of transaction:
Additionally, because layer-2 blocks are used instead of the main blockchain, transactions are much faster and more effective. Through a two-party consensus mechanism called a payment channel, transactions are carried out. As a result, the Lightning Network becomes one of the foundational elements of the Bitcoin ecosystem.
Swift micropayments are also made possible by the Lightning Network. In comparison to the Lightning Network, Bitcoin has a far greater minimum transaction output requirement. The future of Web3 applications like gaming lies in quick micropayments, hence fulfilling this use case is crucial for the chain’s usability.
The Lightning Network allows for quick micropayments, but they can only be profitable if they have extremely low transaction costs. Often, inefficient transaction processing causes the blockchain to lose market share to rival technologies.
Due to the chain’s rapid expansion, the DeFi ecosystem on Ethereum saw substantial friction in 2021 when gas prices rose. For the Ethereum ecosystem to achieve transaction efficiency, layer-2 technologies like Polygon and Immutable X required to be used. Additionally, companies like Solana and Avalanche gained popularity and market share during this period.
Last but not least, because the Lightning Network removes transactions off the chain, it uses less energy to run nodes. The energy usage to enable such transactions is lower than it would be if they were carried out on the Bitcoin network.which has important implications for sustainability.
Environmental, social, and governance (ESG) investors, who prioritize clean energy. in their investments, have been criticizing Bitcoin. The Lightning Network enhances Bitcoin’s credentials from an ESG standpoint by lowering the energy footprint and moving the majority of transactions off the Bitcoin blockchain.
Potential drawbacks and risks of the Lightning Network
The Lightning Network is not without its drawbacks despite introducing a crucial dimension to improve the capabilities of the Bitcoin Network throughout the blockchain trilemma. The following are the main concerns.
- The cost and difficulty of joining the Lightning Network.
- The risk of a counterparty during transactions.
- The lack of functional scalability.
Once payment channels between the sender and the receiver are established.The Lightning Network improves transaction efficiency, but channel setup is laborious. The Lightning Network will require users to move their money there and lock it inside a channel. The cost of transferring the money to the Lightning Network is high.
Money is still at risk when the funds are locked into the channel and the exchange of transactions between the two parties starts. Technical problems on the channel could cause funds to become stranded.The counterparty could decide to stop the channel and confiscate the funds if the user goes offline. The risks associated with being offline are reduced by watchtowers and Lightning service providers. But that gives the network a new vector of centralization.
There is currently no reliable way to completely eliminate the counterparty risk.That a user on the Lightning Network faces once the channel is open. Another more significant restriction applies to the Lightning Network.
Because the payment channels are designed to be used only between two parties. They are not seamless. Because of this, a company that wishes to pay or transact with many counter-parties. They must build separate channels for each of them and manage them separately. The business would be subject to counterparty risk on each of those channels by virtue of the setup.
Lightning Network future of bitcoin?
The Lightning Network is one of the most well-known layer-2 solutions. Usage data show the network’s expansion.They are still quite low when compared to those of even the newest layer-2 chains on Ethereum. Lightning Labs is, nevertheless, steadily building up its ecosystem for the future.
As a result, the Lightning Network has seen increased adoption. The Lightning Network has almost 5,400 BTC worth $145 million locked up, according to 1ml.com, an analytics software on the network. Despite being used by almost 16,400 nodes and 75,700 channels. the typical transaction only costs 0.0016 satoshis ($0.000000443). Making it a highly viable option for micro transactions.
Supported Wallet:Lightning Network future of bitcoin
There are a few wallets that support the Lightning Network, and they are all mobile-friendly, unlike the Lightning Network’s early days. Users of Android and iOS devices can utilize wallets like Breez, Wallet of Satoshi, and Eclair to conduct transactions on the Lightning Network that is future of bitcoin.
As was already established, Lightning Labs has increased the toolkit required for the network’s developer and user environment. The result, Lightning Network is also seeing the emergence of DeFi, liquidity providers, non fungible tokens (NFTs), and gaming applications that are comparable to those on the Ethereum blockchain.
Now more cryptocurrency exchanges begin to embrace the protocol, the Lightning Network will be accessible to as many traders as feasible. Traders can quickly and cheaply withdraw smaller amounts of Bitcoin from exchanges that use the Lightning Network.
Watchtowers, the network’s stewards, guard users from fraud. When nodes go offline, scams involving offline transactions occur on payment channels. When a counterparty tries to shut down the payment channel to steal funds, the Watchtower notices it, freezes the offline node’s funds, and punishes the offending party.
The difficulties that the Lightning Network faces are numerous. This ecosystem is gradually beginning to be developed for future experiences that is more user-intuitive, robust, and scalable.
