DigiShield is a difficulty readjustment algorithm originally developed for DigiByte.
who is use digishield in other blockchains?dogecoinOn March 12, 2014, version 1.6 of the Dogecoin client was announced. Along with allowing for there to be a fixed reward per block, the new client update also introduced a new difficulty algorithm called DigiShield. The main goal of the new difficulty algorithm, adopted from the Digibyte altcoin, was to prevent multipools from being able to mine (and thereby profit) off the coin, reducing the price of the coin drastically, along with forcing single-coin miners to deal with the rise in difficulty the pools left in their wake. Thanks to the algorithm's near-instant change in difficulty, any multipool entering the Dogecoin network will immediately leave, as the difficulty of mining will spike upwards severely, causing a drop in profitability and, ultimately, an absence of multipools.

https://z.cash/blog/new-alpha-release-faster-block-times.htmlUbiq - Smart ContractsWe have ported Digibyte's Digishield v3 difficulty adjustment algorithm to an Ethereum code base, the same difficulty algorithm recently chosen by the Zcash development team.
The new codebase allows for difficulty retargeting every 88 second block using the Digishield algorithm. This reacts to changes in hashrate each block to increase difficulty and increase attack costs for miners.

https://github.com/casinocoin/casinocoinNautilusCoinNautiluscoin uses DigiShield, an innovative anti-multipool mechanism. Multipool is a mining method that is used to mine coins at a very low difficulty in relation to their net pool hash. This allows many coins to be quickly and easily mined before the difficulty increases. Once the difficulty increases, the multipool miners dump the coins on the market and go aay, and, as the result, the righteous miners are left with a very high difficulty and very few new minable coins. This causes a drop in price and frustration among the committed community members & miners. DigiShield protects the system against multipool mining and ensures greater confidence in the coin
