1. Signal Provider creates a signal using our app or Telegram (Discord and other platforms in the future) bots and shares Signal in his channel.
2. Our bot/app sends Signal to our servers.
3. We timestamp and encrypt signal so no one can access them before the publish date.
4. We send encrypted signal on blockchain.
5. During the 30-day period, we check if Signal hit any targets or stopped losses using CEXes or DEXes data.
6. After 30 days, we publish  Signal History on Cryfi’s Leaderboard, where anyone can see and verify Signal history on the blockchain
