The 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.
