The original source code for the World Wide Web sold at Sotheby’s on Wednesday for $5.4 million, up from a starting bid of just $1,000.

       The code was sold by Tim Ber-ners-Lee, a computer scientist credited with writing the source code that forms the ba-s-is of the World Wide Web. Ber-n--ers-Lee consigned the code for auction by attaching it to an NFT, a type of smart contract that uses blockchain tech.

       “The process of bringing this NFT to auction has offered me the opportunity to look back in time to the moment I first sat down to write this code thirty years ago, and reflect on how far the web has come since then,” said Berners-Lee in a statement after the sale. “I am thrilled that the initiatives Ro-semary and I support will benefit from the sale of this NFT.”

       The code was written in 1990 and 1991. For the auction, it was manifested as a salable collectible in four ways.
