# About Lightning Network

The Lightning Network (LN) is a Layer 2 payment protocol that operates on top of the Bitcoin blockchain. It is designed to facilitate fast transactions among participating nodes and is often considered a solution to the scalability problem that Bitcoin faces.

Thanks to its low fees of just [0.003%](https://cointelegraph.com/news/bitcoin-lightning-network-is-1-000x-cheaper-than-visa-and-mastercard-data) and a minimum payment amount of $0.0003, the Lightning Network has become a reliable payment network.&#x20;

Several major exchanges, such as [Binance](https://www.theblock.co/post/239905/binance-bitcoin-lightning-network), [Bitfinex](https://blog.bitfinex.com/announcements/bitfinexs-lightning-network-capacity-is-now-even-better/), [Kraken](https://blog.kraken.com/post/13502/kraken-now-supports-instant-lightning-network-btc-transactions/), [OKX](https://www.okx.com/support/hc/en-us/articles/360059600412-OKX-supports-Lightning-Network-for-faster-cheaper-BTC-transactions), and [OKCoin](https://blog.okcoin.com/okcoin-integrates-lightning-network-for-99-lower-fees-and-near-instant-transaction-for-off-chain-deposits-withdrawals/) already support Lightning Network payments, and even more businesses, including [Coinbase](https://twitter.com/brian_armstrong/status/1644794656570617856), are expected to adopt the protocol.&#x20;

Over 200 millions users already have exposure to Lightning Network through Binance and [Cash App](https://bitcoinmagazine.com/business/cash-app-enables-bitcoin-lightning-payments-for-40-million-users).&#x20;

Tether, a popular stablecoin, has expressed [interest](https://bitcoinmagazine.com/technical/tether-sent-using-the-lightning-network) in migrating to the Bitcoin blockchain with advances in the Lightning Network. With the launch of [Taproot Assets Protocol](https://lightning.engineering/posts/2023-05-16-taproot-assets-v0.2/) and [RGB](https://www.rgbfaq.com/what-is-rgb) on the Lightning Network, the introduction of USDT is imminent.

Companies that accept Lightning Network payments may benefit from attracting potential customers who prefer to use this payment protocol. Kaminari, in turn, helps businesses process Lightning Network payments by providing a user-friendly platform that enables merchants to manage their transactions and monitor their virtual balance.
