- Low fees are maintained in DigiByte thanks to the MultiAlgo approach working in conjunction with MultiShield (originally known as DigiShield). MultiShield calls for block difficulty readjustment between every single block on the chain; currently blocks last 15 seconds. This continuous difficulty readjustment allows us to combat any bad actors which may wish to manipulate the DigiByte chain.
- Manipulation may be done by a large pool or a single entity with a great amount of hash power mining blocks on the chain; thus, increasing the difficulty of the chain. In some coins such as Bitcoin or Litecoin difficulty is readjusted every 2016 blocks at approximately 10mins each and 2mins respectively. Meaning that Bitcoin’s difficulty is readjusted about every two weeks. This system can allow for large bad actors to mine a coin and then abandon it, leaving it with a difficulty level far too high for the present hash rate – and so transactions can be frozen, and the chain stopped until there is a difficulty readjustment and or enough hash power to mine the chain. In such a case users may be faced with a choice - pay exorbitant fees or have their transactions frozen. In an extreme case the whole chain could be frozen completely for extended periods of time.
- DigiByte does not face this problem as its difficulty is readjusted per block every 15 seconds. This innovation was a technological breakthrough and was adopted by several other coins in the cryptocurrency environment such as Bitcoin Cash, Dogecoin, Startcoin, Zcash, Aurora Coin, Bitcoin Gold, BitTokens, Creative Coin, Granite, Huncoin, Monacoin, Mooncoin, Nautiluscoin, Quatloo, Sakura Coin, Scorecoin, SmartCoin, StartCoin, SuperiorCoin and Ubiq.
- This difficulty readjustment along with the MultiAlgo approach allows DigiByte to maintain the lowest fees of any UTXO – PoW – chain in the world. Currently fees on the DigiByte blockchain are at about 0.0001 DGB per transaction of 100,000 DGB sent. This depends on the amount sent and currently 100,000 DGB are worth around $1000.00 with the fee being less than 0.000001 cents. It would take 1,000,000 transactions of 100,000 DGB to equal 1 penny’s worth. This was tested on a Ledger Nano S set to the low fees setting.
