Does your consensus algorithm exist already? was it already implemented/tested in some proof of concept or is just on paper?
Dusk combines tested technologies but at the same time presents a consensus method underlying the blockchain that is a lot different of what we have seen before. Stealth addresses, Ring CT layer technology, Algorand and even Cryptonote are all used for inspiration. These technologies are all tested and used.
However, dismissing the technological breakthrough of SBA* (Dusk's consensus algorithm) as a simple combination of Algorand with Cryptonote (stealth addresses, Ring CT, etc), is the equivalent of dismissing Bitcoin because it combines Hashcash with digital timestamping services
.
SBA* provides several novelties that are not in Algorand and certainly not in Cryptonote. The latter uses proof-of-work that 1) sooner or later will face severe restriction by states because of excessive consumption of energy 2) requires specialized equipment and 3) promotes pool centralization. Algorand on the other hand is completely open, oriented to permissioned networks and does not even foresees reward incentives. Simply combining the 2 technologies also is not possible since they are incompatible (Algorand works only if the stake of any single node is completely open which goes completely against the philosophy of Cryptonote). SBA* is INSPIRED by these technologies and we mainly refer to them to explain how parts of the system work and how some of the technology is taken from the field and is thus tested, it however evolves toward completely different directions and presents novelties that IMHO qualify SBA* as a breakthrough:
1 - Blind bidding solves staking with anonymity
2 - The segregation of operations makes it possible to create the first ever economy being centralized pool averse
3 - It solves elegantly also the nothing-at-stake problem through its voting system
