Bitcoin developer Paul Sztorc shared a detailed critique on October 4. He claims the Lightning Network hides poor user experiences from the public. The Lightning Network is a secondary payment system that moves small transactions off the main Bitcoin ledger. Sztorc wrote that custodial services handle more than eighty percent of these payments. A custodial service is a platform that holds your coins for you.

The Lightning Network records transactions privately by design. Public data cannot prove how many payments use third-party accounts. Pending transactions wait in the mempool, which is a waiting room for the ledger. Sztorc did not answer requests for comment on his exact count. He compared the current marketing push to the fraud at Theranos, a failed health testing company. Developers argue that the system works better today. Another Bitcoin developer called the daily experience still too inconvenient. The debate continues as merchants test different wallets, which are apps that store your coins.

Engineers proposed the network in 2016. They designed it to scale the main Bitcoin chain. Each block contains a hash, which is a unique digital fingerprint. Scaling means processing more transactions without making the main ledger slow. The original Poon-Dryja paper outlined this design years ago. The system routes coins through temporary channels between users. If a channel runs dry, the money must move back to the main ledger. Users connect to a node, which is a computer that tracks the ledger. This process requires a small network fee, which is the charge you pay to route the transaction.

Direct peer-to-peer transfers cost fractions of a cent. Third-party accounts charge withdrawal fees and hold balances. Sztorc says the industry promotes the wrong model. You should care because most Bitcoin purchases still rely on a middleman that charges fees.
