We’ve had great traction with our support of Ethereum on Azure. The existing Proof-of-Work solution has been deployed tens of thousands of times across a variety of industry verticals. Through the extensive development on our platform, we’ve received great feedback from the community that has helped us shape our next Ethereum ledger product. I’m excited to announce the release of Ethereum Proof-of-Authority on Azure.
Proof-of-Work is a Sybil-resistance mechanism that leverages computation costs to self-regulate the network and allow fair participation. This works great in anonymous, open networks where competition for cryptocurrency promotes security on the network. However, in private/consortium networks the underlying ether has no value. An alternative protocol, Proof-of-Authority, is more suitable for permissioned networks where all consensus participants are known and reputable. Without the need for mining, Proof-of-Authority is more efficient while still retaining Byzantine fault tolerance.
