A. Introduction

A next-generation ultrafast and autonomous public chain platform.

B. Industry

For public chain platforms, there are three key requirements: large scalability, fast finality and high reliability. Currently, a large number of public chain platforms are still at the developing stage, making great efforts to meet the three requirements. However, blockchain technology alone cannot bring this goal come true. As a project dedicated to the establishment of a next-generation public chain platform, JURA has designed an adapted platform combining the core technologies of Ethereum, IOTA and Filecoin, in order to fulfill the three decisive requirements. There are also a lot of competitive projects on the market, including Zilliqa adopting the Sharding technology, Rchain, Nerthus focusing on the DAG technology, and etc. (7/10)

C. Mode

JURA has claimed its ambition to build an underlying public chain with the ability to outperform that of Ethereum. One of its important features is extremely low transaction fee. The monthly cost of running a full node is as low as $3. To maintain the operation of the system, three roles are designated in JURA: judger, storager and coordinator. Rewards will be distributed to these three when they have correctly performed their respective duties. A judger is responsible for validating transactions and resolving conflicts. To become a judger, users have to stake a certain sum of tokens. They can take their tokens back and receive rewards only when they make right decisions. In case of any incorrect and dishonest behaviors, the tokens will be confiscated by the system. A storager is responsible for storing large, unstructured data within JURA, while a coordinator is responsible for monitoring the information of the shards, whose rewards are distributed in accordance with its contribution. Only full-node users can choose to take at least one of the three roles mentioned. (6.5/10)

D. Technology

JURA is powered by 4 core technologies: FUSUS data structure, dynamically monitored and distributed Sharding (DMDS), Proof of Utility (PoU) consensus mechanism and artificial intelligence. FUSUS is an individual account-based DAG-lattice. With FUSUS, the way in which transactions are sent and received adapts flexibly to the real-time traffic volume of the network, which helps lower cost and improve transaction speed. Two consensus mechanisms are adopted in JURA. A Proof of Verifiable Random Time (PoVRT) mechanism is proposed to generate verifiable random time. It ensures that the sending node has correctly waited for the proper random time, and thus guarantees the security of the system. In addition, JURA also proposes a Proof of Utility mechanism to monitor the whole system, the functionality of which is similar to a traditional dynamic, multi-dimensional reputation system. The adoption of DMDS enables the parallel processing of requests through node partitioning and makes sure that when a node is discarded, it will be quickly routed to another backup shard. Meanwhile, the whole network is well monitored with PoU mechanism rating the behavior of its participants. Besides, JURA also introduces artificial intelligence to carry out transaction-level filtering and warn malicious nodes. Generally speaking, JURA provides a combination of several state-of-art technologies. However, the whitepaper only mentions the adoption of these technologies without explaining why they are chosen among all other options. Besides, as an underlying public blockchain, the whitepaper of JURA is not rigorous enough, as it lacks forcible argument for the security and feasibility of the project. The project has not been open-sourced so far. Therefore, more observation is recommended. (6.5/10)

E. Ecosystem

Twitter: 8,024 followers; Telegram: 35,470 members. The main purpose is investment. JURA’s strategic partners include OneLedger, Cortex Labs, Hero Node, SciDex and etc. (6.5/10)

F. Team

The team is basically composed of Chinese and Korean members who base in various locations, such as China, Korea and America. Donglin Wu, co-founder, holds a B.S. in Math from Harvard University. Donglin is a seasoned entrepreneur. Alex Dang, co-founder, holds a Ph.D. in Biomedical Engineering from Colombia University. Alex is a fresh graduate and previously worked as an external consultant at Jacob D Fuchsberg Law Firm. Iris Yang, co-founder, received her B.S. in Applied Math from Colombia University. Iris previously worked as a researcher at Fortune Ventures. Cameron Wang, Chief Cryptographer and System Architect, holds a Ph.D. in Math from Princeton University and previously worked as a teaching assistant at Princeton. Although most of the members graduated from world-class universities, the team lacks a solid academic background and rich experience in blockchain development, which means little help for this project. Not to mention that many of its members have just graduated. Besides, the members are settled in different locations, which may tie down the overall efficiency. (6/10)

G. Conclusion

The ambition of JURA is to establish a next-generation public blockchain. Technically speaking, it plans to integrate a variety of technologies, including DAG, Sharding, artificial intelligence and etc. However, as an underlying public chain, the whitepaper of JURA fails to provide rigorous evidence for the security and feasibility of its innovative data structure and consensus mechanism. The team background is of little help regarding the development of this project. In addition, given to the intense competition among public chain projects, the implementation of JURA can be quite worrisome.
