Solaris (XLR) is a decentralized privacy-oriented cryptocurrency network launched on 18th March 2017 using the NIST5 hashing algorithm. After a while, the team wanted to improve on the security and payment features of the network, so a decision was made to completely replace the code base. The network relaunched on the 7th October 2017 with the newly improved features and new XEVAN algorithm.
Solaris was built on the base of PIVX that forked from Dash, which in turn is based on Bitcoin. The team focused on achieving near instantaneous transactions that remain private and secure with the help of the Zerocoin Protocol. After an update, masternodes were implemented into the Solaris network and they started providing services for the new features such as a Decentralized Governance System with voting from owners of such nodes, as well as Instant Send.
