This algorithm is used in various altcoins to regulate difficulty.
This method was first introduced in Megacoin and used to adjust the difficulty of the network every block adaptively.
How Blockchains Maintain Consistent Block Times
The logic of the algorithm is shown as follows: KGW = 1 + (0.7084 * pow((double(PastBlocksMass)/double(144)), -1.228)) The algorithm runs in a loop that goes through a set of predetermined blocks (PastBlockMass) and calculates a new readjustment value.
The core idea behind this algorithm is to develop an adaptive difficulty regulation mechanism that can readjust the difficulty in response to rapid spikes in hash rates.
Kimoto Gravity Well (KGW) ensures that the time between blocks remains approximately the same.
In Bitcoin, the difficulty is adjusted every 2016 blocks, but in KGW the difficulty is adjusted at every block.
This algorithm is vulnerable to time warp attacks, which, allow an attacker to enjoy less difficulty in creating new blocks temporarily.
This attack allows a time window where the difficulty becomes low, and the attacker can quickly generate many coins at a fast rate.
