What is the Bitcoin Lightning Network?
The Bitcoin Lightning Network is a layer-two scaling solution built on top of the Bitcoin blockchain. It aims to enable faster, cheaper, and more scalable transactions by allowing users to create off-chain transaction channels.
What are the advantages of using the Bitcoin Lightning Network?
- By enabling most transactions to be processed off-chain, the Bitcoin Lightning Network alleviates congestion on the Bitcoin blockchain, allowing for a higher number of transactions per second.
- Bitcoin Lightning Network transactions are near-instantaneous as they don't require confirmation by miners. Payments can be settled within seconds or even milliseconds.
- Transactions on the Bitcoin Lightning Network typically have significantly lower fees compared to Bitcoin network transactions. This makes microtransactions economically viable.
- The Bitcoin Lightning Network doesn't reveal information about individual transactions on the blockchain, which could protect users’ privacy. Users can refer to their Binance web/app to check past transaction information.
