VeChain has introduced a new virtual node to improve high availability and resilience by automatically redirecting requests to live nodes and retrying failed requests. This approach adds a valuable safety net to the existing node infrastructure, which is important as single nodes often fail and outages are likely to occur. The virtual node has been battle-tested in different dApps over the past six months and adjustments have been made to handle outages. VeChain has two types of nodes: Authority nodes, which validate all blockchain transactions and require a full KYC and application procedure, and Economic nodes, which provide stability to the ecosystem and require a minimum of 1,000,000 VET to access.
