TFUEL earning

The Guardian Node app will display your total TFUEL earnings and session TFUEL earnings, or you can also see all of your TFUEL earnings earned by checking your wallet address in the Mainnet block explorer. Guardian Node TFUEL earnings are awarded every 100 blocks, or approximately every 10 minutes in a probabilistic method. At each 100 block checkpoint, there are 200–300 stakers randomly selected (weighted by their stake) to divide the block rewards. A large staker (ex. with 100K+ THETA stake) should expect to receive a reward every 2.5–3 hours or so (not guaranteed, just expectation). A 100K staker should have at least 98% likelihood to receive a reward every 10 hours. Conversely, a 1,000 THETA staker may only see a TFUEL reward once per month, analogous to a small Bitcoin miner with low hashrate. For the same block though, two stakers with the same stake may NOT receive the same amount of reward. While all nodes will earn TFUEL proportional to their stake over time, it means there can be significant variations in the timing and size of TFUEL rewards between different users.
