Before explaining the eHRC technology, let me introduce what a machine gun mining pool is.
The academic name of the machine gun mining pool is mutilpool, which is a composite mining pool, which provides a mining pool with the ability to automatically switch mining currencies. This kind of mining pool will convert the harvested different currencies into a certain currency (usually Bitcoin) to pay the miners during payment and settlement. Machine gun mining pools usually gather a lot of computing power. The computing power of Scrypt algorithm is mostly between a few Gs and more than ten Gs. Before the difficulty adjustment, make full use of the advantages of large computing power and have a high chance of grabbing blocks.
Both Bitcoin and Litecoin adjust the difficulty every 2016 blocks. Bitcoin generates 10 minutes for each block, and Litecoin generates 2.5 minutes for each block. In this way, you will wait a long time for each difficulty adjustment, and this time will be fully utilized by the machine gun mining pool to conduct block grabbing behaviors with low difficulty through large computing power.
The eHRC technology is designed to address this problem. The English definition of eHRC technology is as follows:
eHRC uses the standard Bitcoin protocol to calculate the next block difficulty, but adds 2 extra historical block lookups, or block average times to calculate the new difficulty more accurately. The difficulty ReTarget has been increased to every block.
eHRC uses the standard Bitcoin protocol to calculate the difficulty of the next block, but adds 2 additional historical blocks or average time checks to more accurately calculate the difficulty of the new block. At the same time, make each block undergo difficulty redirection. In this way, since each block must be calculated based on the current computing power, the mining of each block is fair.
Therefore, eHRC technology is a new difficulty calculation rule against machine gun pools. It uses the method of calculating the difficulty of each block once, so that the machine gun pool cannot use the difficulty adjustment interval to grab blocks, so that the machine gun pool cannot reflect the advantage of large computing power and mines fairly with the miners.
On April 25, 2014, Feathercoin has successfully completed a controlled hard fork and upgraded to version 0.8.6.2. We ushered in the eHRC era.
