Bitcoin Daily: Austria Backs Pandemic-Related Blockchain Initiative; Ride-Hailing App Ryde Will Enable Bitcoin Payments
PYMNTS.com: The government of Austria is backing the creation of a pandemic-related mobile application based on the blockchain, CoinDesk reported. Its Federal Ministry for Digital and Economic Affairs provided a grant of $67,600 to the QualiSig program that taps into portions of the country’s digital identity infrastructure to make prototypes involving wellness data, fraud prevention and fake news. One prototype lets people verify coronavirus testers. Another prototype brings together signed coronavirus test results with the digital citizenship of an individual to let them go to a musical performance or travel by plane, while an additional prototype seeks to stop fake news. The prototypes harness the Ardor blockchain. It was reported that they will not be ready to go into a live environment for eight months at a minimum.

Cryptobriefing: One-liner: “Parent-and-child chain” architecture with lightweight smart contract capabilities and no blockchain bloat. Ardor is operated by Jelurida and has its roots in the Nxt blockchain, which was one of the first PoS networks and has been running since 2013. Ardor was created by the same team to overcome the adoption challenges of traditional linear blockchain architecture. These include the use of a single token, a lack of customization capability, and blockchain bloating as a result of processing and storing every single transaction in the same way. Ardor aims to overcome this with an architecture that comprises the main parent chain and child chains. Each child chain is entirely customizable according to user requirements and can use its own token. Ardor also makes use of stateless, lightweight smart contracts programmed in Java.

Wendy O: So I definitely remember #Peercoin was the first PoS, but it was hybrid PoW. I'm also pretty sure #NXT was the first Pure PoS, not $ALGO. Can someone clarify?
