What is Opal?
Opal (OPAL) is a decentralised, open-source cryptocurrency released in September 2014 as a re-branded OnyxCoin. The project's main focus is on developing what it calls "Opacity technologies", which implement several unique features in the cryptocoin's blockchain. These include encrypted messaging (messages can be encrypted, stored and sent anonymously to contacts), opaque addresses (mathematical functions to protect personal financial transactions and keep them hidden from public view).
