Paul Sztorc Questions Bitcoin Lightning Network Usability
Bitcoin developer Paul Sztorc has renewed criticism of the Lightning Network, arguing that Bitcoin users are overstating how well the layer-2 payment system works. He said in an October 4 post on X that many people do not realize how poor the Lightning Network user experience is and claimed there has been a long-running effort to misrepresent it. According to Cointelegraph, Sztorc also said custodial Lightning services account for more than 80% of payments, comparing their promotion to a “vast campaign of fraud” and referencing Elizabeth Holmes’ Theranos. Because Lightning payments are private by design, that share cannot be verified from public network data alone, and Sztorc did not respond to requests for comment. His remarks have revived a broader debate among Bitcoin developers over whether Lightning has made Bitcoin easier to use or whether the community has become too focused on the protocol’s progress while overlooking its limitations.The criticism centers on usability, liquidity and the gap between technical capability and everyday spending. Lightning was built to make Bitcoin transactions faster and cheaper without recording every payment on-chain, but users and businesses still face friction when liquidity is not available in the right place at the right time. Routing can fail, especially for larger payments that require multiple hops, and even Lightning’s head of liquidity, Alex Bosworth, said this month that the system is “extremely slow compared to tap to pay” in a privacy-focused setup. Jesse Shrader, co-founder and chief executive of Lightning infrastructure provider Amboss, said the network’s liquidity requirements are challenging at first but can be handled with current tools and automation. He said most users can reach 99% reliability for everyday payments of around $100, while Amboss simulations put the success rate for $100 payments at 99.66%. Still, those figures are not a verified network-wide measure of real-world use. River estimated Lightning processed $1.17 billion in transaction volume across 5.22 million transactions in November 2025, while CoinGate said Lightning accounted for 9.6% of Bitcoin payments in the first half of 2026. Even so, critics and supporters alike say the available data measures activity, not necessarily mainstream usability.
