A High-Throughput Flexible Blockchain Platform Based on Trusted Sharding Computation
MultiVAC is a blockchain platform of next-generation for developing large-scale and highly loaded dApps. To solve the problem of scaling, it uses technology based on fragmentation of the main chain into shards.
MultiVAC creates a high-speed network for dApps. In general, MultiVAC provides an infrastructure for dApps that allows you to work with a high degree of security and reliability. MultiVAC is the first to offer the Sharding model based on proven random functions (VRF) for transactions and storage. VRF seems to be an interesting technology that is becoming more and more popular among blockchain projects. One of the well-known projects implementing VRF technology is Ontology.
The working principle on VRF + Sharding technologies. The shard belongs to the subgroup of the whole network. For example, if the whole network has two shards, A and B, only one of the two nodes must be selected to process the transaction. In a MultiVAC network, a node is assigned based on VRF to process the transaction. The main mechanism is to generate a random number in the main chain, and then encrypt it with the private key of the node. The end result is a random number that is assigned to a particular shard in accordance with the probabilistic model. Since dApps consist of smart contracts in a public chain, the codes must be executed on all nodes, that significantly increases computational costs. To solve this problem, MultiVAC implemented its own consensus algorithm called "Proof of Instruction" (PoIE). The main focus of PoIE is on the efficient execution of calculations for the performance of smart contracts. MultiVAC is a rather flexible platform for configuring between these three tasks (security, decentralization and scalability). Flexible calculation of shards means that dApps built on MultiVAC can work depending on what parameters are specified by the developers. Developers can choose their own parameters for consistency, usability, partition availability and decentralization level. The shard size is established by the creator of the contract. A greater number of nodes are allocated to ensure availability and security, while a smaller number contributes to higher capacity.
Team: The team of 16 people is working on the implementation of the idea. The development team includes former senior engineers from Google, Tencent and Alibaba, and also researchers from Harvard.
Among the advisor there is a famous person, Roger Lim. He is the founder, partner of the NEO Global Capita fund. He was an adviser in many successful ICOs.
Competitors: often compared with Zilliqa and Quarkchain.
Conclusion: The technologies that MultiVAC plans to use for solving the tasks of scalability, security and decentralization have not found their practical application at this stage, it is not clear whether the market needs will be met, and whether they can work as it was stated. Sharding technology is popular at the moment and many projects are trying to implement it. Probably MultiVAC will be the project that will show the working product with sharding technology. And then they will be able to take a worthy place among the competitors. But it is a completely different story.
