A new report highlights how the Lightning Network has grown in popularity as a way of transferring digital assets quickly and efficiently around the globe. 

On Thursday, CNBC told the story of Alena Vorobiova, a Ukrainian refugee currently seeking sanctuary in Poland. Vorobiova used Lightning to transfer $100 worth of Bitcoin (BTC) from Miami, where it was then withdrawn from an ATM in the equivalent Polish currency — all within the space of three minutes.

That’s the sort of low-cost high-speed transaction that has seen the layer-2 scaling solution for Bitcoin grow 410% in payment volume over the past year.

According to a report by Arcane Research, the number of payments that occurred on the Lightning Network in the past year doubled while the total value of those payments quadrupled.

The report warned that the widely-cited public metrics used to measure Lightning Network adoption — most commonly total value locked (TVL) — underestimate the size of the network as they fail to count private channels and invisible nodes. Additionally, the metrics don’t reflect real-world Lightning Network usage, whereas looking explicitly at payment volume paints a clearer picture of real Lightning adoption.

A partial explanation for the surge in payment is owed to the enormous increase in the number of users who have recently gained access to the Lightning Network. This is through applications like El Salvador’s Chivo Wallet and United States-based payment application CashApp.

Arcane estimated that in August 2021, roughly 100,000 users had access to Lightning payments. By March of this year, over 80 million people had the ability to access payments on the Lightning Network , which shows that there is a large potential user base.

The report found that roughly 50% of the value of all payments came from direct transactions between individuals, or peer-to-peer (P2P) transactions. Almost one-third of the payment value came from exchange withdrawals and deposits, with the remaining 20% coming from purchases made through some form of vendor.

Despite Bitcoin being originally designed as an electronic cash system, the sluggishness of the Bitcoin networks in resolving transactions gave rise to layer-2 solutions. The Lightning Network was launched in March 2018 to provide faster and cheaper BTC transactions.
