FPPS (Full Pay Per Share)
FPPS (Full Pay Per Share) is an enhanced payout model used by mining pools to distribute rewards to miners. In FPPS, miners are paid a fixed amount for each share they contribute to the pool, just like the standard PPS model. FPPS goes a step further by including both the block reward and the transaction fees in the payout, ensuring that miners receive 100% of the reward from both sources.
FPPS (Full Pay Per Share) Explained in Simple Terms
FPPS (Full Pay Per Share) is a variation of the PPS (Pay Per Share) payout system. Like PPS, miners in a pool are paid for every share they submit based on the pool’s difficulty level and block reward. However, unlike the standard PPS model, FPPS includes not only the block reward (the fixed amount of Bitcoin created for each mined block) but also the transaction fees that miners collect from transactions included in that block.
In essence, FPPS ensures that miners receive 100% of both the block reward and transaction fees, distributed proportionally based on their contribution to the pool. This makes FPPS a more favorable option for miners who want a predictable income stream, including rewards from both the mined block and the associated transaction fees.
How FPPS (Full Pay Per Share) Works
The FPPS model works similarly to the standard PPS payout model, with the key difference being that it includes transaction fees in addition to the block reward. Here’s how it works:
Shares Submitted: Miners contribute shares to the pool by solving partial mining puzzles, which are then submitted to the pool.
Block Mined: When the pool successfully mines a block, the pool receives both the block reward (currently 6.25 BTC) and transaction fees (fees collected from Bitcoin transactions included in the block).
Reward Distribution: The pool operator distributes the total rewards (block reward + transaction fees) to miners according to their contribution, with the amount each miner receives being proportional to the shares they submitted.
Full Payment: In FPPS, miners receive a fixed payout for each share, which includes both the block reward and the transaction fees, ensuring they are paid the full reward from both sources.
The FPPS model is beneficial because it provides a more predictable and stable income for miners, as they are guaranteed a payout based on every share they contribute, and the payout includes all of the rewards, not just the block reward.
Example of FPPS (Full Pay Per Share) in Practice
Let’s consider a mining pool that successfully mines a block, and the total reward consists of the following:
Block reward: 6.25 BTC
Transaction fees: 0.25 BTC
Total reward: 6.5 BTC
Miner A contributes 100,000 shares.
Miner B contributes 50,000 shares.
Total shares submitted: 150,000 shares.
The pool payout per share is calculated as:
Payout per share = 6.5 BTC / 150,000 shares = 0.0000433 BTC per share.
Miner A’s payout = 100,000 shares * 0.0000433 BTC = 4.33 BTC.
Miner B’s payout = 50,000 shares * 0.0000433 BTC = 2.165 BTC.
