区块链的开发者是谁,区块链的开发者是指

区块链技术是一种分布式数据库技术，它的开发者是一群有着丰富经验的技术专家和创业者。围绕着区块链技术，他们构建了三个相关的关键词：去中心化、共识机制和智能合约。

去中心化

去中心化是一种分布式的技术，它把数据和计算分散到网络中的多个节点上，不依赖于中心服务器，每个节点都可以自主管理和控制自己的数据。去中心化技术提高了数据的安全性和可靠性，使得数据不会被篡改，也不会因为某个节点的故障而影响整个网络的运行，极大地提高了系统的稳定性。

共识机制

共识机制是区块链技术的核心，它是由网络中的节点协商一致后，确定的一种规则，用来确保数据的安全性和一致性。共识机制有很多种，比如工作量证明、拜占庭容错等，它们都有着不同的特点，可以根据不同的应用场景来选择合适的共识机制。

智能合约

智能合约是一种可编程的自动执行的合同，它是基于区块链技术而开发出来的。智能合约可以帮助双方自动执行合同，从而确保双方的权益。智能合约可以解决传统合同执行中的问题，比如信任问题、不确定性问题等，使得双方能够更加安全、可靠地执行合同。

区块链的开发者们，通过去中心化、共识机制和智能合约这三个关键词，为区块链技术的发展做出了重要的贡献。他们的努力，使得区块链技术在数据安全、可靠性等方面有了显著的提升，为人们带来了便利。

Ⅰ What is the technical strength of Quark Blockchain QKI technical team and the technical support of the developers themselves?

It is not like what the poster said. The Quark team is doing a good job. Quark District Blockchain projects are stable. Why is Quark Blockchain and the team trustworthy?
First of all, Quark Blockchain has a group of young, enthusiastic, and motivated team members. You can often see them interacting with users in the communication group, collecting everyone’s opinions on the project, answering various questions, and discussing the project. s future. In addition, team members are also good friends with each other and some participants offline, and often study and discuss issues face to face. Unlike some project teams, the "written members" only exist in the text introductions on the official website and white papers. Looking at reality, the victims of some runaway projects don’t even know who the team members are? Where do you work? Not to mention meeting each other. Therefore, choosing Quark is choosing a reassurance with dual guarantees in the online world and the real world.
Secondly, during the development process of Quark Blockchain, team members participated in QKI’s trading activities fairly like ordinary participants, and the vast majority of team members purchased QKI in large quantities, which fully confirmed their absolute commitment to the project. confidence. Objectively speaking, the better the project develops, the higher the benefits each Quark Blockchain participant will receive. Therefore, as the core part of the participants, team members have sufficient motivation to do a good job in the project.
Third, from the perspective of technical support, Quark Blockchain has a block browser, all data is open and transparent, there is no falsehood, and there is no possibility of fraud. These data that every participant can see are very important to the circle. Fake projects that make money run away are simply impossible to realize, and this is also the best basis to prove that Quark Blockchain is a real and reliable project.
Finally, the QKI purchased by each participant comes from other users. Point-to-point transactions ensure that transaction funds will not flow into the team's control, and participants do not have to worry about the risks caused by the so-called team money trapping problem.

II Blockchain Developer Contest will launch the challenge of who can become the next Xunlei Wankecoin

In 2017, blockchain technology will undoubtedly set off a new wave of technology after the mobile Internet. , from the three dimensions of technology implementation, commercial application and commercial realization, blockchain is expected to become a new technology that will once again subvert people's digital lifestyle after the mobile Internet. Currently, the new wave of blockchain technology has fascinated more and more developers. Therefore, NEO, a non-profit community-based blockchain project, has joined hands with Microsoft to launch the first domestic blockchain developer competition, aiming to build on the NEO blockchain. The blockchain and Microsoft's development environment and tools have spawned more excellent applications, thus forming a powerful blockchain developer application ecosystem.

Mike Mason, director of technology in the Office of the Chief Technology Officer of ThoughtWorks, a global software consulting firm, said: "People are using blockchain technology in more interesting ways to use it as a 'de-Centralized Applications’ foundation, not just using it for applications like fintech and cryptocurrencies. You must know that the "blue ocean" has never lacked players. Some Internet companies are trying their best to land on the beach and have established that the blockchain industry market has become an inevitable choice for development. In China, Netcenter Technology, a wholly-owned subsidiary of Xunlei, uses blockchain technology in an innovative cloud computing model - "shared computing."

Earlier, Xunlei implanted the concept of sharing economy into the field of cloud computing and created an original "shared computing" model. By collecting users' idle computing resources, it transformed them into enterprise-oriented innovations. Cloud computing services, on the one hand, can effectively solve the social contradiction of tight computing resources and high computing costs, and on the other hand, can greatly reduce the operating costs of enterprises. In August 2017, Xunlei launched a new sharing economy smart hardware Wanke Cloud. Its significance is that in the shared computing ecosystem, Xunlei added blockchain technology to those who share bandwidth and storage through Wanke Cloud smart hardware. Player coins will be issued to users with idle resources such as computing power and computing power.

Wankecoin is a digital asset based on blockchain technology under the Xunlei shared computing ecosystem. The launch of Wanke Coin has made Xunlei a pioneer in China's blockchain technology, and Xunlei's shared computing has many advantages: First, Wanke Coin is based on shared computing and blockchain technology, and ensures users share computing resources through smart contracts. It is equal to the payment and income of the content and cannot be repudiated; secondly, through decentralized ledger records, all transactions are ensured to be true and transparent; thirdly, user copyrights and modification records are registered through the blockchain to protect users' copyrights from infringement.

In fact, blockchain technology has strong advantages in areas such as network security and cross-border payments, and is also of great value in building a community with a shared future in cyberspace. On October 31, 2017, Chen Lei, CEO of Xunlei Group and CEO of Wangxin Technology, proposed the All in blockchain strategy and announced that starting from Wanke Cloud, Xunlei will increase investment in blockchain technology to explore cloud computing and blockchain. Application of chain technology integration. On the day of the press conference, Wanke Cloud also signed a copyright content distribution agreement with 4K Garden, trying to integrate shared computing and blockchain technology to provide a platform for copyright distribution and content distribution. In the future, blockchain will have more application scenarios in Xunlei's shared computing ecosystem. Xunlei’s innovative attempts may provide more inspiration to developers of other blockchain technology applications.

At the same time, as a pioneer in the blockchain application market, Xunlei is also actively guiding the healthy development of blockchain applications, insisting on not doing ICOs or third-party trading platforms, and severely cracking down on violations. A third-party platform for trading Wanqi coins, and uses measures such as the real-name system for Wanqi currency wallets to suppress speculation and hype. Therefore, blockchain application developers should also abide by laws and regulations and avoid risks.

Xunlei’s “Wanke Cloud” is based on blockchain technology and has taken the lead in creating C-side applications of China’s blockchain technology, paving the way for China’s blockchain technology to participate in the development of the global blockchain ecosystem.It has played a driving role and created important value in the development of digital economy. "The history of the development of the Internet is a history of innovation and entrepreneurship of Internet talents." The development of blockchain also requires the support of a large number of talents. We are very much looking forward to the refreshing "blockchain" in the first domestic blockchain developer competition. +” application is born!

Ⅲ What technology development is needed for blockchain

What technology development is needed for blockchain:
1. Blockchain theory: Blockchain developers Being familiar with the theoretical knowledge of blockchain is the most basic requirement for a blockchain developer. The content includes blockchain network architecture, decentralization and other related application technologies. Expanding technical theory is mastery of Ethereum development.
2. Smart Contract: Smart contract is a string of codes that blockchain developers need to write in blockchain programming language. It is a trust mechanism developed after imagining logic according to different scenarios, aiming to eliminate the intervention of third parties. Create an efficient and high-trust blockchain network. Blockchain developers need to realize automatic execution of this string of code, and the operation effect is irreversible.
3. Cryptography: Many blockchain application scenarios have high encryption, and point-to-point encryption mode is a characteristic of cryptography. By studying cryptography, blockchain developers understand encryption concepts such as wallets, keys, and a wide range of encryption and decryption technologies
4. Distributed architecture: Blockchain developers must understand the functions of distributed architecture and networks . Decentralized network is the foundation of the blockchain architecture. The transmission of information in the blockchain network must follow a decentralized approach so that everyone can enjoy the same network rights.

IV What do you think of blockchain developers

I think it is worth it for blockchain developers to develop something that has not yet been developed, and they will definitely look forward to it. .

IV Is it true that the main developer of Bitcoin created a new virtual currency?

According to a report on October 24, Beijing time, Jeff Garzik is the bottom layer of Bitcoin One of the few key developers of the software, he is well aware of the shortcomings of the Bitcoin blockchain. Therefore, he decided to create a better digital currency.

He named the currency Metronome and said it would be the first virtual currency that can be used on different blockchains.

This flexibility means that if a blockchain dies due to developer infighting or no one using it, Metronome users can move their holdings elsewhere. Kajik said this can help Metronome maintain its valuation and ensure long-term survival. To found Metronome, Kajik founded the startup Bloq. Metronome will be officially launched on Tuesday at the Money 20/20 conference in Las Vegas, he said.

Metronome will be generated and supported by automated distributed software that is not controlled by anyoneControl and cannot change. The software will begin auctioning the Metronome currency in December and will retain and use the proceeds from the auction to drive the price of the currency. The rest of the project will be open source, so anyone can develop apps for Metronome.

Bloq will provide developer tools for enterprise users. Of the 10 million Metronome coins that will be auctioned in December, Bloq and other organizations that helped create and promote Metronome will retain 2 million. Every 24 hours, 2,880 new Metronome currencies are born.

Metronome avoids the problems that users often encounter when wishing to transfer from one blockchain to another. That is, users must sell one of the cryptocurrencies they hold and then purchase another cryptocurrency. This incurs transaction fees and may result in the loss of potential appreciation in the currency sold. With Metronome, these are not problems.

When users wish to transfer Metronome to another blockchain, they will be given a digital receipt. They can then send the receipt to another blockchain and then add Metronome to that blockchain.
