Building upon the original Bitcoin. Denarius features changes such as Stealth Addresses, Native TOR, Cross-Chain Atomic Swaps, Proof of Data, Hybrid MasterNode System (Fortuna Stakes), Encrypted Messaging, Multi-Signature Addresses & Transactions, and Tribus (a new PoW hashing algorithm). A maximum of 10,000,000 D is to be created during the hybrid PoW/PoS lifecycle of 3 years, which then transitions to Proof of Stake (6% APR) entirely after the first 3 years.
Denarius has a Hybrid MasterNode system named Fortuna Stakes. It aims to have a fair distribution reward system which ensures that all Fortuna Stakes receive the same income over time. Fortuna Stakes reportedly receive 33% of each POW & POS block that is mined. FS/MN Collateral is 5000 D.
Tribus (Latin for three) is the Proof of Work hashing algorithm used in Denarius. Tribus consists of three of what it believes to be the most popular and secure cryptography algorithms that were featured in the NIST5: JH, Keccak, and Echo.
