DigitalNote [XDN] is one of the first cryptocurrencies that is truly resistant to 51% attacks. This feature is a result of two separate systems that are now implemented: our Proof-of-Work/Proof-of-Stake hybrid distribution and our VRX v3.0 Difficulty Retargeting Algorithm. Since the network is now secured via both Proof-of-Work and Proof-of-Stake, that means an attacker must not only have 51% of the network hashrate but also 51% of the coins (which is highly unlikely). Additionally, the VRX v3.0 Difficulty Retargeting Algorithm insures a balance for both stakers and miners while checking blocks for proper spacing, rejecting them if they have not met one of the main parameters for the chainĀ­.
