Researcher: Lightning network has flaws, and the system is not actually decentralized

Recently, digital preservation researcher David Rosenthal released an overview of the BTC Lightning Network (LN). Proponents of the Lightning Network say the system will increase decentralization and anonymity. But Rosenthal claims that the Lightning Network infrastructure is not actually decentralized, and privacy protection is just empty talk. Rosenthal also emphasized that the Lightning Network charging system also has major flaws, and the transaction fee is far from enough to cover the cost of running nodes.
