Aurora
Pioneering Innovation in Blockchain Technology

Blockchain is deemed to be a cornerstone for establishing a reliable and secure Internet environment. With the most fundamental attribute of trust among the peers on the network, blockchain has made its mark as a remarkable technology that has rendered the value-transmission process transparent and confidential without intervention from intermediaries while making the value exchange more efficient and less costly. As blockchain evolves to expand into other industrial applications, an aurora of wonderful and colorful blockchain possibilities have emerged into the picture, propelling modern blockchain enthusiasts into a wider cosmos of blockchain applications. The above metaphor serves as both the name and the very driving principle behind one such explorer of the blockchain universe–Aurora; a blockchain implementer whose entire journey within the blockchain realm is significantly analogous to the technology’s evolutionary timeline in the past decade.

Aurora Chain (AOA) is Aurora’s proprietary blockchain technology that commits itself to increase operational speed and to create a blockchain tech designed for applications. By providing a solution to many common blockchain challenges, Aurora chain links all industries while promoting the creation of applications, and building a colorful blockchain world. Ushering in a breakthrough into the blockchain world, Aurora Chain offers intelligent application isolation and enables multi-chain parallel expansion to create an extremely high transaction per second (TPS) with security maintenance. To accomplish this mission, Aurora Chain applies DPOS+BFT consensus mechanisms and contracts with “speed of light” operation rate to link industries such as games, big data, AI, and IoT.

Aurora Chain leads the mission for creating lightning fast contracts and facilitating the easy development of applications on the blockchain through a series of techniques like DPOS+BFT consensus mechanisms, P2P Stereo-net, proprietary application isolation, Multi-asset launching, Multi-chain Parallel operation, Pending Zone, upgradable blockchain and Cluster Grouping.

The Driving Force

Since blockchain is most commonly used for digital asset offering, Aurora Chain enables in-depth collaboration with other industries by allowing businesses to embed applications and rules into the blockchain.

Aurora Chain applies EVM virtual machine and Solidity developing languages to write perfect smart contracts essential to incorporate blockchain into other sectors. As public chain supports a contract that is directly related to how closely a blockchain is combined with other industries, Aurora pre-determines that only contracts with an abundant under layer, a high level of freedom, and transparent code can meet the needs of different industries.

Aurora has also been proactive toward the concerns on the transaction throughput (TPS) of many blockchains, which is reported to hinder the blockchain from being combined with other industries. To alleviate this concern, Aurora Chain is focused on boosting the speed of transaction processing. Aurora Chain commits to build upgradable blockchain and realizing automatic upgrading in designated height. Meanwhile, with cluster self-grouping technology, Aurora Chain can reduce users’ data storage costs. The company offers a resolution to difficulties when implementing blockchain technology in applications and speeds up the construction of blockchain ecology. Ensuring immediate application, Aurora Chain emphasizes the combination of ideal and reality, the co-existence of efficiency and practicality. Aurora Chain enables in-depth incorporation with various types of applications to speed up the implementation of blockchain applications.

The Core Attributes

Aurora Chain also uses the delegated proof of stake (DPOS) mechanism due to high transaction speed and high TPS of DPOS consensus mechanism. When AOA balance of an account is higher than five million AOAs, the account can apply for the candidacy of AOA proxy. However, when AOA balance of a proxy candidate is lower than 5 million AOAs, its candidacy will be automatically disqualified. Every address with the balance of AOAs is qualified to vote for proxy candidacy, and the top 101 candidates with the most significant number of votes can automatically become the proxy nodes for packing transactions. Also, every address can only vote for each candidate once with maximum quota of 101 votes. With one vote, 1 AOA needs to be locked till the end of voting. Aurora adds BFT (Byzantine Fault Tolerance) to this DPOS for effectively avoiding forks. A broadcasting network is built among different nodes. Proxy candidates can build up a direct connection through the upper layer network, which enables that BFT mechanism between proxies could be realized quickly. With network layering, Aurora Chain can achieve faster and safer communication.

Aurora Chain builds up a stereoscopic P2P network where there is a broadcasting network among nodes based on user datagram protocol UDP and a long connection among proxy candidates based on TCP.

Through the upper network, a high-speed BFT consensus system can also be realized among proxy candidates. Moreover, a proxy ROOT tree is added to the head of each block to record its status and to boost the speed of verification.

The standard token offering procedure offers to include simplified and regulated token offering methods and procedures that are significantly complex. However, Aurora chain can simplify this procedure of asset offering with the provision of processing speed and capability of expansion with the same level as main chain coins. Through Aurora’s multi-asset token offerings, tokens can be used in the contracts directly and there is no need of introduction of other contracts. Additionally, upgrading a blockchain is difficult after it has been released except when a compulsory fork is applied at the expense of impeding the development of blockchain. But with the LLVM compiler, blockchain code and contract scripts can be put together. Leveraging underlying codes stored within the chain, consensus recognition, and automatic upgrading with designated height could be realized. All clients will upgrade together after the upgraded blockchain is placed on the old version at a specific link. Given the events when any node turns onto self-grouping function, certain nodes in the network will form up a cluster combination, which can participate in transaction verification and storage to reduce users’ data storage costs. Aurora chain helps others with transaction verification, where its users receive an extra bonus resembling a mining mechanism.

Aurora has developed specific apps for blockchain developers, users, and the community. The company’s AOA range of applications is designed to bring innovation in the blockchain development while connecting with Aurora community and developers. The AOA Lite Wallet is a personal mobile wallet developed for account enquiry, receiving, transferring, and account management. The AOA Mainnet Wallet is an app developed for blockchain developers that provides a visualization tool for AOA Mainnet account management, trading, and smart contracts.

Established in the year 2013, Aurora Chain commenced online and simultaneously opened the Aurora chain platform for smart contracts. Over the following years, Aurora chain upgraded the intelligent application isolation technology and the Stereo-net; further improving security and operational speed. Recently in December, the company completed a matured development of multi-chain parallel operation services, cluster grouping technology, and upgradable blockchain technology, implementing cooperation between 30 applications. For the prospective year of 2019 and the future beyond, Aurora is focused on working toward combating anti-quantum attacks and building a blockchain world that is significantly more secure and faster.
