With block 2000000 a new difficulty algorithm will be implemented and activated in PIRL.

This will be done for a few reasons, mainly because PIRL originally uses the Ethereum difficulty adjustment algorithm, but that algo has a slow adjustment and thus is susceptible to being congested by rapid changes in hashrates. This makes mining for smaller miner much more challenging and the network is more susceptible to large fluctuations in hashrate from nice hash or big mining farms for example. One of the biggest complaints of miners is that a young coin is ruined for small miners as soon as the first nice hashers and big farms are on the scene. The difficulty jumps, and your rig is wasting a lot of energy, but not finding many shares. In order to mitigate this, PIRL will switch to an exponential difficulty algorithm. This new difficulty algorithm allows the difficulty to adjust more quickly at upto +/- 10% each block. This means that miners will get their fair share and have less “wasted” time (where previously they were waiting hours for difficulty to adjust to proper levels).

The new algorithm adjusts to keep strong adherence to average 13 second block times, and makes the overall timing more accurate because the new algo adjusts upto +/- 10% of the previous block – so there is a much more rapid adjustment to difficulty. The old algo only adjusts at approximately .0494% per

block. This means that large changes in hash rate will be adjusted for much more quickly, so spikes in difficulty will not linger. The new algo also allows for rapid exponential increases as needed. The difficulty will be adjusted almost immediately and fairness to the small miners will be retained. This is proven technology, that has been implemented in similar ways by other projects too.

What does this really mean to the average miner? This new algo brings more stability and efficiency to mining as the difficulty will be adjusted more quickly so there is less time mining at difficulties that are not accurate at the time. This leads to an increase in mining rewards overall. It also means the network cannot be crippled as easily by large increases or decreases in hash rate from a large nice hash order or from a large mining farm coming online. Additionally, this helps to protect the network against 51% attacks as the difficulty algo will adjust quickly to prevent the network from being overwhelmed in a massive attack.Though this does not provide direct ASIC or nice hash resistance, it does help mitigate their effects.

In conclusion, with this change, the chain will be more stable and efficient. Mining PIRL is currently profitable even while the overall crypto market has been down, and PIRL remains among the top coins in profitability on various mining rating sites. PIRL can be mined effectively with both AMD and NVDIA GPU’s and with a variety of Ethash based miners.
