OpenSea announced today in a series of blog posts that it is adding features to the digital marketplace to “improve authenticity.” The updates include a new way to find and get rid of fake NFTs and a change to the way accounts are verified.
“Copymints” are tokens that copy other non-fungible tokens (NFTs), which has been a problem for platforms like OpenSea. Last year, the platform took down two collections that looked like Bored Ape Yacht Club NFTs but were made to look like the opposite by flipping the image. Even though an NFT’s owner is written on the blockchain, fakes are very common. In February, OpenSea said that more than 80% of the items it took down because they broke the rules were made with its free “minting” tool.
