MultiVAC is the next generation of high-performance public chains designed for large-scale decentralized applications, enabling blockchain systems to scale indefinitely and sustainably through trusted sharding technology. MultiVAC first developed a reliability probability model for selecting shard nodes based on verifiable random functions, and applied this model to key links of blockchain transactions, computing, storage, etc., making mission objectives achieve high reliability with the participation of some nodes. MultiVAC shards transactions in the network according to the canonical UTXO account model, selects miners for billing through the reliability probability model, and raises corporate chain performance to enterprise-level commercial levels. As the first public chain for elastic computing models in the blockchain space, MultiVAC innovates with PoIE consensus for verifiable computing tasks, BISC instruction set designed for blockchain, and MVM virtual machine with universal computing power, enabling developers to independently balance consistency in distributed applications. Availability and zoning tolerance requirements provide complete support for complex business logic at the application layer, so as to build a diversified public chain ecosystem more conveniently.
