Cologne, Germany, September 15, 2022. Today at 7:42 a.m., the most important public blockchain Ethereum was switched to a new consensus-building procedure. The switch from "Proof of Work" to "Proof of Stake" has been worked on for years. It is the first time an active blockchain has been successfully migrated to a new process while it is running. Ethereum is considered the most important blockchain because most of the newer blockchain-related processes and products, such as in digital arts ("NFTs") and alternative currencies, are based on it. Through the transition, consensus on a new state of the chain is no longer established through the massive use of computing time, but through a process that involves shareholders of the network. According to forecasts, the consumption of computing power - and thus of energy - will be reduced by up to 99% as a result of this changeover. 

Stephan Noller, UBIRCH CEO: "The Ubirch Trust Platform previously relied on multiple public chains. Ethereum has always been the most important of these. In order to let our customers maximally participate in the current improvements, Ubirch will immediately discontinue the use of Public Chains that continue to use the energy-intensive "Proof of Work" process."

• Public Blockchain Ethereum successfully masters the switch of the consensus algorithm from "Proof of Work" to "Proof of Stake" 
• Blockchain energy consumption drastically reduced by up to 99% as a result
• Ubirch therefore discontinues use of energy-intensive public chains with "Proof of Work" method
