Nexus is a project created to build a new, and newly designed, blockchain. It is quantum-resistant by design, and in order to create what they call a three-dimensional decentralized ledger, Nexus employs no less than three consensus mechanisms. The structure being for their ‘Prime’, or general, channel, to use a traditional Proof-Of-Work for its consensus among blocks on their ledger. There any user can engage in mining, which is searching for a 308-digit clusters that you can do even with just a CPU. That area, the Prime Channel, is also used to formulate data usage in quantum physics research. The second channel, which they call their Hashing Channel, also employs Proof-Of-Work, the difference here is the usage of Hashcash and not prime clusters like in the Prime Channel. This algorithm is closer to the one Bitcoin uses. The third channel and third consensus mechanism is Proof-Of-Holdings, basically the new iteration of Proof-Of-Stake. Combining the three of those is thought to allow for a freer, more liberal environment for blockchain users.
