Litecoinpool
Introducing the first genuine pay-per-share (PPS) Litecoin mining pool, where each valid share you contribute is immediately added to your account at the prevailing PPS rate. This rate, measured in litecoins, incorporates earnings from merged-mined cryptocurrencies like Dogecoin, leading to greater payouts compared to standard Litecoin pools. Thanks to the benefits of merged mining, there are no fees to worry about; in fact, your total earnings will surpass those from a zero-fee PPS model. This pool is not a PPLNS, SMPPS, or RBPPS setup: we guarantee payment for your contributions, irrespective of whether the pool has resolved enough blocks to meet the earnings generated. Unlike other systems where miners receive rewards only when a block matures—often risking the chance of blocks being orphaned and yielding no reward—our PPS pool assumes the risk of bad luck so you can enjoy consistent earnings without the hassle of variance or orphaned blocks. With our unique approach, you can mine with confidence, knowing your work will be compensated fairly and reliably.

SoloPool.org
A solo mining pool is structured such that each miner operates independently, meaning that only the miner who successfully discovers a block receives the entire reward, while others in the pool do not earn anything. The time it takes to find a block relies on both the miner's hashrate and an element of chance. After initiating the mining process, the average hashrate can only be accurately calculated after a minimum duration of 30 minutes. This hashrate assessment is based on the shares submitted by the miner, which may fluctuate compared to the figures displayed in the mining software. Furthermore, mining pools ensure that they only retain your coins for as long as necessary to confirm transactions and process payouts. Each mining pool operates under a reward system tied to block discovery, commonly referred to as SOLO, wherein rewards are granted strictly for finding blocks, with no compensation for submitted shares or time invested. Mining itself is a highly intricate computational task, and results can vary significantly; for instance, a miner might discover nine blocks with a luck value below 20%, yet also hit a block with an astonishing luck value of 700%, illustrating the unpredictable nature of this endeavor. This variability in luck highlights the challenges and excitement that come with solo mining.
