Understanding Bitcoin Lightning Network And How To Use It

The Bitcoin Lightning Network serves as a solution to Bitcoin's scalability issues, particularly concerning transaction processing limitations. Without scalability improvements, Bitcoin risks becoming an outdated digital asset.

While Bitcoin was designed with blockchain technology to enhance transaction security, its low transactions per second (TPS) capability remains a significant drawback.

The Bitcoin Lightning Network functions as a layer 2 payment protocol atop the Bitcoin blockchain, aiming to expedite and economize Bitcoin transaction costs. In essence, the Lightning Network accelerates Bitcoin transactions, rendering them faster and more efficient.

By employing smart contracts, this network tackles Bitcoin's scalability constraints regarding TPS by utilizing off-chain payment channels, without compromising Bitcoin's decentralization and security. Moreover, the Lightning Network facilitates small-scale Bitcoin transactions.

The Lightning Network boasts a capacity to process up to 1,000,000 transactions per second (TPS), whereas Bitcoin is limited to approximately 7 TPS.

Background Of The Lightning Network

It's imperative to note that Bitcoin transactions are restricted, managing only 7 transactions per second with a 1-megabyte block size. In contrast, payment behemoths like Visa can process 4,000 transactions per second, scalable up to 65,000 transactions per second.

Bitcoin's block size is capped at just 1 megabyte, a decision made to uphold network security. Larger block sizes would prolong transaction verification times.

Due to scalability issues, Bitcoin underwent forks, resulting in the emergence of Bitcoin and Bitcoin Cash. Bitcoin Cash opted to increase block size to accommodate more transactions.

Bitcoin transactions typically take around 10 minutes due to its decentralized nature, necessitating consensus from nodes globally, contributing to extended transaction times.

With the surge in Bitcoin transactions and the burgeoning demand for crypto adoption, addressing these limitations becomes imperative for Bitcoin's continued growth.

How Does The Lightning Network Work?

In processing transactions, the Lightning Network operates with two nodes: Bitcoin nodes and Lightning Network nodes. Nodes refer to computers or individuals executing Bitcoin programs and monitoring Bitcoin transactions.

The disparity between Bitcoin nodes and Lightning Network nodes lies in their transaction verification processes. Bitcoin nodes validate every transaction on the Bitcoin network, whereas Lightning Network nodes authenticate transactions directly by engaging with them.

The Lightning Network employs source routing and onion routing technologies. When a Lightning transaction is dispatched, the computer automatically computes the optimal route based on the current network status. Subsequently, the protocol encrypts the route for security.

Each Lightning Network node possesses a Lightning wallet, necessitating operators to deposit/top-up BTC into the Lightning wallet. To initiate a payment channel, users must stake a certain amount of BTC into the payment channel. Presently, the Lightning Network is suited for conducting small BTC transactions.

How To Use The Lightning Network?

To utilize the Bitcoin Lightning Network, users must initially download wallets supporting the Lightning Network, such as Phoenix Wallet, Breez Wallet, Wallet of Satoshi, and Blink Wallet, among others. Subsequently, deposit BTC to initiate transactions.

For transactions to proceed, both the sender and receiver must possess Lightning Network-compatible wallets connected to the Lightning Network.

The Lightning Network operates using the smallest Bitcoin unit, Satoshi, where one Bitcoin equals 100 million Satoshis. Leveraging Satoshis enables transactions at a minuscule scale, allowing users to send and receive tiny amounts of Bitcoin at nominal costs.
