About the Lightning Network

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

The Bitcoin network is designed to be decentralized and secure by keeping records on each Bitcoin node. It would take half of the entire hash rate network to manipulate the transaction record, which is nearly impossible to achieve. However, this popularity also comes with a flaw — the number of transactions the Bitcoin network can process per second is limited by the generation speed of each block and the size of each block, which clearly could not meet the growing demand for transactions resulting from rapidly growing bitcoin owners and users. To solve this problem, the developers created layers above the mainnet, where the first layer was the main blockchain.

The Lightning Network is a second-layer agreement based on the Bitcoin network that includes a peer-to-peer system for micropayment channels that allow instantaneous transactions between participating nodes, thus solving the scalability problem of the Bitcoin network. Broadly speaking, it is a “green channel” built outside of the Bitcoin mainchain to handle a large number of high-frequency or small-sized transactions with assured security.

The Lightning Network was first implemented in the Bitcoin network in 2018 and its use has grown considerably rapidly since then. According to the latest Arcane Lightning Status Report, the number of payouts has roughly doubled and the value of payouts has increased by more than 400% compared to 2021 (measured in USD). According to the current Lightning Network real-time statistics of 1ml (, there are 17,783 Lightning Network nodes running 86,854 channels, 4,567.33 BTC network capacity in total.
