A Customizable Public Blockchain for Industrial- scale dApps

Read the full PDF report

Summary

MultiVAC is creating a public blockchain for industrial-grade dApps. The project adopts  a  sharding  mechanism  utilising  probabilistic  models  to  achieve consensus. MultiVAC also introduces proprietary technologies that provide high flexibility for developers to dynamically adjust several parameters according to the complexities of their business needs. In short, the team seeks to build a blockchain that is extremely fast, scalable and robust.

Company overview

Incorporated in Singapore, MultiVAC has an objective of developing a high- performance public blockchain. The platform will provide flexibility for users to resolve the blockchain trilemma, allowing them to balance the factors between security,  decentralisation  and  scalability.  MultiVAC  utilises  a  probabilistic sharding model combined with a uniquely designed MultiVAC Virtual Machine (MVM)  to  create  a  trusted  and  flexible  execution  environment.  Some fundamental issues the team would like to solve includes:

•The enhancement of security and issues in typical sharding networks without compromising the scalability factor

•To improve the fair and efficient mechanism of node selection by adding an unpredictability layer to enhance the selection process

•To verify the honest execution of computational tasks

Commercial & Technical Strategy

MultiVAC utilises a random sharding technique to achieve higher efficiency and fairness in node selection. This is done without compromising the security and scalability needed for blockchains to achieve industry scale. Furthermore, the MultiVAC  Virtual  Machine  (MVM)  is  equipped  with  a  proprietary  designed blockchain instruction set (BISC) and Proof of Instruction Execution (PoIE) that allow users to decide on the parameters tradeoff between security, scalability and decentralisation. Several noteworthy features include:

•Sharding with Verifiable Random Functions (VRF) – A probability model that is applied to the sharding mechanism, ensuring true randomness, lower cost and higher efficiency in node selection. This function is further enhanced with an unpredictability layer under Verifiable Unpredictable Functions (VUF) to increase the robustness of randomness.

•UTXO  (Unspent  Transaction  Output)  and  Byzantine  Fault  Tolerance Mechanism – This methodology combined with dynamic shard adjustment achieves  the  in-shard  consensus  of  the  network,  solving  the  issue  of expensive synchronisation costs that exist in current sharding technologies.

•MultiVAC Virtual Machine (MVM) – The platform that supports the flexible execution environment. Two main features are embedded within:

a)Proprietary BISC (Blockchain Instruction Set Computer) model, which is a set of instructions bridging the connectivity between the hardware and software.

b)PoIE  (Proof  of  Instruction  Execution)  consensus  algorithm  uses  the Merkle Tree data structure to verify honest execution within the network
