The inventor behind the original source code for the World Wide Web is planning on having it auctioned as a nonfungible token (NFT) to secure digital ownership over the code considered by many to be one of the most significant inventions of all time.

Tim Berners-Lee unveiled the plans Tuesday, with the official auction page by auction house Sotheby’s stating that bids starting at $1,000 will be accepted from June 23 to June 30.

The auction, titled “This Changed Everything,” will allow individuals to bid on the original time-stamped files containing the source code for the application invented by Berners-Lee in 1989.
