NFTs are digital files that serve as digital signatures to certify who owns photos, videos and other online media. Dorsey's 15-year old tweet is one of the most famous tweets ever on the platform and could attract bidders to pay a high price for the digital memorabilia. "There is only one unique signed version of the tweet, and if the creator agrees to sell, you can own it forever." A tweet's buyer will get an autographed digital certificate, signed using cryptography, that will include metadata of the original tweet, according to the Valuables website. The tweet will continue to be available on the Twitter website.
