Odaily Planet Daily News According to a series of recently published patent application documents, the Layer2 and NFT fields seem to be the focus of PayPal’s research and development work. Since September 21, PayPal has published three patent applications: Among them, one patent application proposes a so-called new "method and system" to enable off-chain transactions through the NFT market. Another application mentions the concept of "omniverses," hinting at a product that handles multiple metaverses. PayPal said it developed an "online transaction processor" that can provide recommendations on which digital assets users should purchase based on their blockchain preferences and which metaverses they interact with most. A third application describes another conceptual "online transaction processor." The goal of this processor is to facilitate payments between users and merchants running on different network layers (L1 and L2) in a more efficient manner. (Blockworks)
