VeChain: Testnet launches PoA 2.0 soon
The VeChain Foundation has announced the soon start of the testnet for the Proof of Authority 2.0.
Byzantine Fault Tolerance Protocol (BFT) prototype completes implementation.
Peter Zhou, chief scientist of the VeChain Foundation, has made an update on the introduction of the SURFACE consensus algorithm, also known as Proof of Authority, PoA, 2.0. Via his Twitter account, Zhou said that he had made “some good progress” with the core developers on the introduction of SURFACE. Testnet announces start date for the implementation of PoA 2.0.
Testnet launches PoA 2.0 The Vechain core dev and I have made some good progress on implementing PoA2.0. We will soon launch a new testnet implementing VIP-193, allowing faster tx confirmation. Moreover, I personally finished prototyping VIP-200 that will give us BFT finality.
Introduced as VIP-193, running on blockchain VeChainThor SURFACE is a consensus algorithm responding to the demand of businesses and application. Its goal is to improve the scalability and performance of the network by enabling faster transaction confirmation time.
SURFACE takes the best from blockchains like Ethereum and Bitcoin which use the Nakamoto Consensus, and applies an asynchronous Byzantine Fault Tolerance (BFT) mechanism. In this way, the network operates with a dual consensus mechanism ready to work in scenarios with optimal conditions and protected against possible bad actors, DDoS attacks, among other vulnerabilities, guaranteeing the security of the blockchain.
Improving VeChainThor blockchain capabilities
As mentioned above, Zhou confirmed that prototype for VIP-200 allows block of VeChainThor reach BFT finality. By allowing blocks to carry “extra finality related messages this can be achieved”. Thus, the nodes will be able to update their BFT status and achieve finality.
