MultiVACThe design features of MultiVAC are purpose-built for integration with large-scale decentralized applications (dApps). As a core aspect of the protocol, developers can customize parameters for consistency, availability and partition tolerance, providing a high degree of user autonomy over the blockchain infrastructure. MultiVAC implements a novel approach to scalability for large-scale dApp development through a sharding model called Verifiable Random Functions (VRF) for transactions, computation, and storage. MultiVAC operates on the MultiVAC Virtual Machine (MVM), which includes the Blockchain Instruction Set Computer (BISC). MVM currently supports C compilation based on LLVM, to eventually integrate other languages such as Java and Go. For data storage and retrieval, MultiVAC employs a mechanism based on both Hash and Merkle Roots, in addition to a sharded storage network based on the native VRF model. MultiVAC utilizes a Proof of Instruction Execution (PoIE) consensus mechanism, which verifies accurate computation in a way similar to the proof of replication. The PoIE consensus algorithm is directly embedded into MVM, validating each executed instruction.
