Solaris XLR was released on March 18, 2017. On Saturday, October 7, 2017 UTC time, the Solaris blockchain was restarted. The previous Nist5 algorithm was replaced by XEVAN. XEVAN was created by Bitsend developers and since then has proven to be a stable ASIC resistant and efficient algorithm. The Xevan hashing algorithm is a unique combination of a double X17 difficulty algorithm with an extension to 128 bits. Solaris has a number of unique features that set it apart from other cryptocurrencies, some of which include a decentralized governance system using masternodes and an "instant send" feature that allows transactions to be confirmed instantly.
