Topic: Verifiable Computation over the HelixTangle,by USC and Helix Cognitive Computing (Read 271 times)

Founded in 2017, Helix Cognitive Computing GmbH (www.hlx.ai) is a Berlin-based technology company that is dedicated to developing and creating a sustainable digital ecosystem that interconnects Everyone and Everything by using a next-generation peer-to-peer digital exchange network - the HelixNetwork.

The HelixNetwork consists of the HelixMesh Protocol, it's own distributed ledger the HelixTangle and a native currency – the HLX coin.

The HelixMesh protocol is based on the double-consensus (on- and off- chain) MeshCash framework. The main advantage over existing Byzantine Fault Tolerant (BFT) consensus protocols is a high degree of flexibility: HelixMesh can be deployed in both permissionless (by implementing the Proof-Of-Contribution abstraction) and permissioned environments. Moreover, virtually any BFT consensus can be used for the off-chain layer of HelixMesh. As a result, the liveness vs safety tradeoffs are not dictated by the protocol itself but may be adjusted based on the particular use-case requirements. This makes HelixMesh a robust blueprint for consensus protocols over IoT-sourced distributed ledgers. On a longer timescale, we envision a global interconnected network of HelixMesh-based specialized DLTs.

In collaboration with the University of Southern California, Helix Cognitive Computing has recently published the paper "Verifiable Computation over the HelixTangle“. To give you a little insight into our document you can read a summary of the paper here.


Abstract
The cryptocurrency platforms such as BitCoin and Ethereum rely on Proof-of-Work (PoW) consensus algorithm. Following the PoW, the nodes that solve the computationally intensive cryptographic puzzle is given the opportunity to create the next block in return for an incentive. Such puzzle-solving nodes are called „mining nodes," and its owners' are referred to as miners. Mining nodes are powerful computation platforms with the ability to perform computationally-intensive tasks. Although contemporary PoW computations demand high computation resources, the outcome of the PoW is not practical as the result of the computation is not used for any other applications except securing the blockchain. Using the mining nodes to execute practical algorithms for applications such as artificial intelligence, protein folding, and video processing would increase the effectiveness of the mining nodes while securing the blockchain. However, the distribution of computation tasks and sensitive data among trustless mining nodes leads to security vulnerabilities. Besides, the lack of technologies for verifying the result of the computation performed by the mining nodes makes verifiable computation impractical. In this work, we formulate the verifiable computation problem, discuss the existing work, and propose a novel platform for verifiable computation for the Helix Tangle.
