The Way Hawk Network Empower the Internet of Things with Blockchain

How does blockchain technology become a new generation of infrastructure that balances decentralization, security, and performance? How does blockchain combine with the Internet of Things to form a trusted Internet of Things? From the current point of view, the IoT is a trigger point in the future. The IoT fits naturally with blockchain in many aspects. Objectively speaking, the combination of the IoT and blockchain has other challenges besides the distributed data storage and edge computing mentioned above. The combination of the IoT and blockchain is extremely complex. To face billions of devices with different computing power, it is required to solve the problems of interoperability, security, privacy, and incentives of heterogeneous systems. 

Hawk Network has clear steps to solve these problems one by one. The goal is to make billions of devices in the Internet of Things safely accessible to blockchains and to achieve interoperability between devices and data. Ultimately, in order to achieve a real landing, ultra-large-scale Internet of Things equipment must achieve fast, low-cost transactions, and can protect privacy, meet the equipment interconnection of heterogeneous systems, and encourage more nodes to enter, increase deployment scale, and reduce operating costs. To solve these problems, Hawk Network implements a three-step approach.

User Proof of Stake Consensus Algorithm for Distributed Internet of Things

UPOS consensus algorithm is more suitable for distributed Internet of Things. Hawk Network adopts UPOS (User Proof of Stake) consensus mechanism. UPOS is designed to solve the drawbacks of traditional DPOS (Delegated Proof of Stake) consensus mechanism. For example, the representative nodes of block generation in DPOS mechanism are relatively fixed, which is difficult to meet the needs of complex blockchain architecture in the Internet of Things. The improvement of UPOS is to propose a random rotation mechanism of proxy rights and interests consensus. Through cryptography technology, a group of nodes is randomly selected from the dynamic node pool to generate blocks. At the same time, the communication complexity of PBFT is optimized to improve transaction throughput. One of the advantages of Random Rotation Agency Equity Consensus Mechanism is that it adapts to Hawk Network's master-sub-chain architecture, and can support complex block-chain architecture by dynamically partitioning the pool of proxy nodes to ensure the efficient and safe operation of the mainchain and subchain elastic architecture.

Adopts Chain-in-chain Architecture to Solve the Interconnection Problem of Heterogeneous Networks

Because of different scenarios and requirements, in order to achieve communication between heterogeneous systems, Hawk Network does not adopt a common chain applicable to all nodes, but allows heterogeneous devices to form an internal network first, and finally connect to a large backbone network to achieve connectivity with other networks. Hawk Network adopts chain-in-chain architecture to solve the interconnection problem of heterogeneous networks. There is a single main chain, and there are many different subchains on the main chain. Applications and devices running on different sub-chains are different and can be customized to solve the heterogeneity of the Internet of Things. Through the chain-in-chain approach, the sub-chains of different scenarios serve different needs. For example, sub-chains running on devices with weak storage can use Nimble-like Wimble architecture to reduce storage; subchains focusing on payment scenarios may not need to run smart contracts. These different chains need to transmit digital assets and states. Cross-chain protocols can achieve interoperability between chains. Of course, it also needs to consider the impact on cross-chain performance and security implications. 

Make it Portable, Trustworthy and Support Large Anonymous Collections

Trusted Computing Environment Empowers the Internet of Thing. Hawk Network has improved the technology of the Internet of Things to make it portable, trustworthy and support large anonymous collections. Subsequently, on the premise of depending on trusted computing environment, cryptographic tools will be used to implement lightweight privacy protection intelligent contracts. Thus, the Internet of Things can be empowered with blockchain and edge computing technology. Once the technology is mature and the problems of performance, interoperability, cost, privacy, security and so on are solved, trusted Internet of Things has a high probability of becoming the next trigger point of the blockchain. Therefore, it can promote the development of the IoT, make the IoT to eventually become the mainstream, and ultimately bring more convenient, safe and credible services to people through technology and incentive mechanism.
