Fig. 9. Different types of blockchain-based on permission and trust models. As seen in Fig. 9, we can classify the permission and trust model of consensus algorithms in four types: • Permissionless and public: Consensus algorithms like PoW are in this class. The best applications of this...
Such a structure allows faster block creation in the sidechain and, accordingly, faster processing of transactions without the loss of security and without increasing the volume of the block. Such a two-level blockchain is of the greatest interest for the creation of a cascade system of state ...

Cross chain transactions are the next step in the evolution of cryptocurrency adoption. The easier it becomes to unite the hundreds of blockchain's that currently exist in silos, the faster the technology as a whole can begin to scale and achieve mass adoption. For more read the documentation...
The game theory framework makes complicated game types of problems simple to understand situations more clearly. Therefore, stochastic models with a game framework have been widely studied [24,25] and these models are applied for various areas including the blockchain [25,26,27] and the business...
Moreover, in combination with blockchain technology, the CPA scheme allows a cloud server to generate proof of possession of the EHR data and an auditor to check the correctness of the proof (please refer to [19] for the detailed application model). Contributions. In this work, we observe ...
In addition, blockchain use has brought attention to decentralized identifiers and self-sovereign identity as an alternatives to traditional authentication methods. User authentication is key to securing networks. Learn about the different authentication types available, including 2FA, biometrics and ...
