By Ultrain’s Chief Cryptologist Husen Wang

RPoS Consensus is divided into the following stages

1、 There are two committees, C1 and C2. Both can be joined freely with deposited stakes.

2、 C1 periodically generates a random number r using Verifiable Random Function. Proposers and Voters are selected by the Fisher-Yates shuffle algorithm with priorities.

3、 All proposers initiate their blocks, where all voters verify and vote upon the highest priority proposer’s block. The votes are signed with aggregatable signature. This makes lightweight client and cross chain transaction verification possible.

4、 After collecting enough votes through BFT algorithm, all nodes generate its block independently, and the corresponding proposer gets rewarded.

Compared with DPoS：

1、 RPoS is more decentralized and safe. Since DPoS has limited amount of nodes, it leaves room for “under the table” collusion between nodes, which compromises the overall security and fairness of the network. For example, during the random number generation process, fairness is required. However, nodes in DPoS can collude to predict or manipulate future random number without being detected.

2、 With larger amount of nodes, RPoS is harder to be attacked when compared with DPoS~There are a limited number of nodes in DPoS, thus easier to be attacked, which results in the overall failure of the network or a fork.

Compared with Dfinity:

1. The BLS signature of Dfinity needs to assume security in Gap Diffie-Hellman (GDH) group , which might

2. limit the security level of randomness. Threshold signature requires pairing calculation that runs slowly. During the process of threshold signature, members need to exchange information, which may result in a slow threshold signature and increase vulnerability to malicious attack. RPoS limits threshold signature to voting and changes voters frequently without group setup problem.

3. If participants can join and exit freely the group, it may lead to stolen of private key and predictable randomness.

4. The signature of groups cannot be compared to that of the PoW system (such as bitcoin), thus the security of block confirmation cannot be guaranteed and results in a longer confirmation time.

Compared with Algorand:

1. Algorand selects its committee member, especially the proposers, based on probability. Which might result in multiple proposers that causes the issue of “network storm”, which increases the overall consumption of bandwidth for nodes.

2. RPoS utilizes threshold signature algorithm, which composes a smaller voter message that is easy to transmit within the network and for client side verification.

3. RPoS introduces an incentive mechanism for both proposer and voter, a double signature punishment system that further improves overall security.

In addition:

1. RPoS optimizes layer0 message transmission, to minimizes arrival time for message propogation.

2. The RPoS plans to introduce TEE and KYC mechanism to further improve the overall system security.

- An analytical artilce by Guo Rei, Ultrain's CEO and Co-founder:

"Blockchain has been described as a revolutionary technology — that the technology born from Bitcoin will change our lives and guide us towards a future way of living. This hype is somewhat dampened, however, by the disappointing performance of existing blockchain infrastructure. Ever since Ethereum was introduced to the world, Blockchain 3.0 has been the ultimate vision that will fully realize the true value of the Internet. It is widely believed that a virtual business network, perfectly compatible with the concepts of decentralization, security, and ideal performance, will eventually be realized......"

Ultrain'e CTO and Co-founder Ning Li elaborated the difference between Blockchain and Distributed Database, two terms often confused by the general public.

Please read the full article at " https://medium.com/ultrain-chain/the-difference-between-blockchain-and-a-distributed-database-556f8361e6b3"

Li mentioned in his previous article on the evolution of blockchain technology, he will try to continue a series of articles that further explain the world of blockchain. His goal in this article was to breakdown the difference in nature between blockchains and distributed databases, and in his upcoming article he will elaborate how smart contracts can be perceived as “nuclear power” for the world of blockchain, rather than an interface for external services. I will also describe a series of valuable applications for smart contracts.

A great article by Ultrain. I like Gup's quote on "the most important aspect of a project’s success is often its economic design. A reasonable and logical model can preserve the overall security of a blockchain through economic incentives." In fact, it synchronizes with my own understanding. I think that token and incentives are heart and soul of blockhain.

DON'T GET ME WRONG, the actual technology implementation and achievement are extremely important as well, but getting the communities, and in this case, the miners on board are crucial for Ultrian's success! as those miners are the one providing services. I believe they can achieve the so called "win win situation". I mean 80% of the rev are going back to the miners!

This looks pretty solid to me Ultrain, attaboy!

Usage of the Utility Token:
1) Purchasing computing power using UGAS: A DApp running on Ultrain needs to purchase the computing power for running its code using UGAS when its smart contract is running. Cost = Amount x Price. Amount indicates the amount of UGAS to be consumed for this running, and Price indicates the price of UGAS. Ultrain monitors the market price of UGAS by using the Oracle machine mechanism and dynamically adjusts the price, ensuring that the operating costs of DApps are maintained at a relatively stable level for a period of time.                                                                               

2) Purchasing third-party services using UGAS: DApps running on Ultrain can purchase, using UGAS, third-party services deployed on Ultrain, such as the authentication service, credit service, and zero-knowledge proof service.                                                                                                                     

3) Obtaining tokens: All nodes (mining rigs) participating in mintage and computing must stake a certain amount of UGAS to participate in the economic system of Ultrain.
