About Lightning Network

In February 2015, Bitcoin developers Joseph Poon and Thaddeus Dryja published an article titled "Bitcoin Lightning Network: Scalable Off-chain Instant Payment", brought the Lightning Network with the concept of "scalable off-chain payment" to the public.

The Bitcoin network is designed to be decentralized and secure by recording ledgers on every Bitcoin node. It would require half of the whole hash rate network to manipulate the transaction record, which is almost impossible to achieve. However, this popularity also comes along with the shortcoming---the amount of transactions that Bitcoin network can process per second is limited by the speed of generating each block and the size of each block, which clearly could not meet the increasing transaction demand resulting from fast growing Bitcoin owners and users. To solve this problem, developers created layers on top of the main network, where the first layer was the primary blockchain.

The Lightning Network is a second layer agreement based on Bitcoin network that features a peer-to-peer system for micropayment channels which enable instant transactions among participating nodes thus resolving the Bitcoin network scalability problem. Generally speaking, it is a "green path" built outside the Bitcoin main chain in order to manage a large number of high-frequency or small transactions with security ensured.

The Lightning Network was first implemented into the Bitcoin network in 2018 and the usage of it has been growing significantly fast since then. According to Arcane's latest Lightning state report, the number of payments roughly doubled and the value of the payments increased more than 400% over 2021 (measured in USD). According to today's real-time Lightning Network statistics from 1ml ( there are 17,783 Lightning Network nodes running 86,854 channels, 4,567.33 BTC network capacity in total.
