It wasn't sarcasm, there's another word you need to look up in the dictionary. I am sorry you never got proper education, but you need to understand the words you use instead of implying false statements.
Quote from link: "And so the race to patent these decentralized applications is on. Scanning global patent registries turns up dozens of active claimants filing patents on blockchain tech, including teams from major corporations. If granted, anyone who wanted to use a blockchain technology like any one successfully patented would have to pay that patent holder a license fee. " *See that last line. That is NOT a free public ledger since one person or person holding the patent can control the technology. Thanks for showing up and playing....
