1. How many years will it take for KDA miners to mine all the KDA coins? The total supply of KDA coins is 1 billion, of which 70% (700 million) are mined by miners. The mining period is approximately 120 years. 2. How is the KDA coin miner reward calculated? The calculation of the KDA coin miner reward is related to the block reward, miner hash rate, and the total network hash rate, as follows: - Basic formula: Miner reward = (miner hash rate ÷ total network hash rate) × block reward. - Block reward: The KDA coin block reward will vary over time. Currently, the reward per block is approximately 0.99 KDA (this figure may fluctuate due to network conditions, etc.). - Hash rate share: Hash rate refers to the hashing capacity of a miner's mining equipment per unit time. A miner's hash rate as a percentage of the total network hash rate determines their share of the rewards. For example, if the total network hashrate is 1000 Th/s and a miner's hashrate is 10 Th/s, representing a 1% share, and the block reward is 1 KDA, the miner would theoretically receive 0.01 KDA. In addition, if a miner joins a mining pool, the pool's fees are deducted. The actual reward is calculated as: theoretical reward × (1 - pool fee rate).
