Simple Explanation: How Light Node Participation Works in QNet 1: The network checks if your node is online Every 4 hours, the QNet network verifies that your device is active. But it’s not a simple internet ping. Instead, it uses a secure cryptographic challenge to confirm your node is really participating. Think of it like the network asking your phone: “Are you really there? Prove it.” 2: Your phone gets a random check time Each 4-hour period has 240 one-minute slots. Your node is randomly assigned one of those minutes. So: - The network doesn’t check everyone at the same time. - Your check happens once during the 4-hour window. - You cannot predict when it will happen. This prevents people from trying to cheat the system. 3: The challenge-response process When your time arrives: i: A genesis node sends a random cryptographic challenge to your device. ii: Your device signs the challenge using a special key. iii: Your device sends the signed proof back to the network. If the response is valid, the network confirms: ✅ Your node is online ✅ Your node participated in the network 4: There are 3 chances to respond If the first node doesn’t receive a reply: - Two backup nodes try again. So you actually have three chances to respond. If all three fail, that round is missed. 5: Missing checks doesn’t instantly punish you Your node only becomes inactive after: 5 consecutive missed rounds Since each round is 4 hours, that means: 5 × 4 hours = 20 hours offline Then the node becomes inactive. You can simply press the reactivate button in the app to start again. 6: Your wallet is never exposed The system uses two different cryptographic keys: Wallet key - Controls your funds - Never used for ping checks Ping key - Created when your node registers - Used only to sign participation responses This keeps your wallet completely safe. The cryptography used is Dilithium3, which is designed to resist attacks from future quantum computers. 7: Rewards are delayed slightly Rewards are not sent instantly. Here’s the process: i: Participation data is collected. ii: It’s added into something called a MacroBlock. iii: The network finalizes it using consensus. iv: Rewards are distributed one epoch later. Since an epoch is 4 hours, rewards arrive about 4 hours after the participation window closes. This delay ensures the network agrees on the data before paying rewards.
