"With an estimated limit of 500 transactions per second (TPS) per payment channel (under current network conditions), Lightning has a throughput of more than 40 million TPS, the equivalent of 14.4 TB size blocks. This is more than 1000x the capacity of VISA, which can only handle upwards of 150 million TPS a day or a maximum of 24,000 TPS at once."

This is bullshit. First the chances that ends of channels are going at 500tps in any permanent or serious way is ridiculous. Then there's the fact that a ⚡ transaction may take a number of those channels to deliver. Comparing it to a Visa payer to payee transaction is dishonest.

Yes, ⚡ is better, but let's not lie to make it so.

This article tries to conflate Liquid sidechain as something that is a part of Bitcoin.

It's not. It's a completely separate centralized ledger run by a federation of corporations. It's not open, permissionless, censorship-resistant or decentralized. It's an antithesis to Bitcoin.

It's just a bunch of companies piggypacking on the success of Bitcoin, and trying to build a financial system of Bitcoin on a digital ledger which they control.
