NKN, or New Kind of Network, is an open-source protocol for public blockchain-based peer-to-peer Networks to share network bandwidth and Internet connectivity. The project was launched in January 2018 and lists Stephen Wolfram, creator of Mathematica and Wolfram|Alpha, and Whitfield Diffie, inventor of public-key cryptography as advisors. NKN Mainnet was launched in July 2019 and has up to 25,000 full consensus nodes (more than Bitcoin or Ethereum).
