  • Why do you need my email address?

    In order to establish 2 factor authentication and to enable communication with customers, the ChainIt Approval Network links your blockchain identity to your email address

  • What does Web1, Web2 and Web3 mean?

    The Internet began in its infancy during the early 1990s and Web1 refers to those early days where websites were static pages with little or no interaction.
    Web2 refers to the uptake of HTML5 where websites to date are interactive, dynamic and can behave as applications. However these interactions take place between you and centralized servers for example Facebook and Instagram servers. As such, you place your trust with these centralized services.
    Web3 is where you can optionally participate as part of a network, placing your trust with the network rather than with a centralized authority.

    For example you could be part of the Bitcoin network by hosting your own node.
