The Sloot Digital Coding System, was a data sharing technique which could allegedly store a complete movie in 8 kilobytes of data—orders of magnitude greater compression than the best currently available technology as of the 2020s. It was claimed to have been developed in 1995 by Romke Jan Bernhard Sloot (27 August 1945, Groningen – 11 July 1999, Nieuwegein), a Dutch electronics engineer. Sloot died suddenly on July 11, 1999, of a heart attack, just days before the conclusion of a contract to sell the invention. The full source code was never recovered, and the technique and claim has since never been reproduced or verified.
