『一』What exactly is the Bitcoin blockchain technology that Microsoft is interested in?

Blockchain is an important concept of Bitcoin, which is essentially A decentralized database that serves as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
The blockchain is public on the Internet and can be queried in every offline Bitcoin wallet data. The functionality of a Bitcoin wallet relies on confirmation with the blockchain, and a valid check is called a confirmation. Usually a transaction requires several confirmations before it can proceed. Lightweight Bitcoin wallets use online confirmations, which means no blockchain data is downloaded to device storage.
Many altcoins of Bitcoin also use the same design, but are slightly different in proof of work and algorithm. For example, using proof of stake and SCrypt, etc.

Blockchain timestamp service and proof of existence
This concept was proposed in Satoshi Nakamoto’s white paper [1], who created the first block, the “Genesis block".
On January 3, 2009, Satoshi Nakamoto, the founder of Bitcoin, left a sentence in the genesis block that can never be modified:
“The Times 03/Jan/2009 Chancellor on brink of second lout for banks (on January 3, 2009, the chancellor was on the verge of implementing a second round of bank bailout)."
It was then that the British chancellor of the exchequer, Darling, was forced to consider a second bailout of the banks. In a time of crisis, this sentence was the headline of a front-page article in The Times that day.
Blockchain's timestamp service and existence proof, the time when the first blockchain was generated and the events that were happening at that time are permanently retained.
The Bitcoin company BTCC launched a service "Millennium Chain" in 2015, which is a blockchain engraving service, using the above principles. Users can engrave text on the blockchain through this service and save it permanently.
Bitcoin, Litecoin, Ruitai Coin, and Qianjin Card are all digital currencies based on blockchain technology.

『二』 [Blockchain] What is Bystack launched by Bytom

Before introducing Bystack, let’s briefly introduce Bytom, which is one of the three major domestic public chains. One, referred to as Bytom, consists of the abbreviation of Byte + Atom. Byte means the digital world; Atom means the physical world; Bytom means the bridge between the digital world and the atomic world.

The atomic world is not the atomic world written in science fiction novels. Here we can understand it as atomic assets, that is, the warrants for the counterparts in the traditional physical world., equity, dividends, bonds, intelligence information, forecast information, stocks and other financial derivatives.

The biggest feature of Bytom is that it is a dedicated blockchain platform focusing on the asset field and has its own unique business model.

Simply put, the purpose of Bytom is to connect the bit world and the atomic world, and build a decentralized network for the registration and circulation of diversified assets.

To sum it up in one sentence, it is: It is a multi-asset interactive protocol used to connect the digital world and the atomic world, and link online and offline.

Bystack is the BUTXO model BaaS platform with one main chain and multiple side chains pioneered by the Bytom team. It is also Bytom’s biggest strategy this year and its flagship product in the next 20 years.

Chang Chai (founder of Bytom) once said: Bystack is Bytom’s business solution. Bytom is equivalent to a bare engine. Bystack is a car. Bystack is not a side chain, but a BaaS platform that integrates main and side chains. It is Bytom+Vapor+other components.

1. Bystack’s technical architecture

Bystack is a general blockchain application stack platform that inherits and implements the three-layer blockchain architecture, consisting of the Bytom main chain and the Vapor side. Chain, Blockcenter middle platform, and access components such as Bycoin, Byone, and Bystore.

Relying on the Bytom public blockchain technology platform and Vapor side chain technology, and using Federation as the interactive protocol between the main chain and the side chain, it provides a channel for value transmission and lays a solid foundation for upper-layer applications. .

Blockcenter, as the core system of the entire blockchain enterprise-level service platform, on the one hand expands the capabilities of the underlying main and side chains, on the other hand abstracts the underlying blockchain technology and provides a typical application development framework. Also provides the necessary capabilities for maintenance, monitoring and upgrades.

2. Bystack node election

Bystack side chain node election includes four roles: side chain initiator, relay node, consensus node and voting principal.

Side chain initiator: It is the first side chain on the Bytom chain initiated by the Bytom Foundation;

Relay node: It is designated by the side chain initiator, mainly It is to protect the security of assets on the side chain. The technical threshold is relatively high. There is no open election this time;

Consensus node: divided into formal consensus node and alternative consensus node.The formal consensus node is responsible for producing blocks; the formal consensus node exits, and the alternative consensus nodes are promoted to consensus nodes according to the number of votes received;

Voting principal: Holding any amount of BTM (coin holders) is a vote Delegators can participate in the election of Bystack consensus nodes by voting and receive dividend rewards.

This time Bystack will recruit 10 formal consensus nodes and 32 alternative consensus nodes. The annual mortgage income of the formal nodes is expected to be 10%-60%. In the first year of node operation, the Bytom Foundation will use 10 million BTM as block rewards for official nodes (reward ratio is 60.98%) and alternative nodes (reward ratio is 39.02%).

The threshold for this node election is 1 million BTM holders. If you do not have 1 million BTM holders, there are two ways to participate: one is to recruit a few friends to make up 1 million BTM, and then participate in the node election ; The second is to vote for the promising nodes with the BTM you currently hold, and then receive dividends. The dividend rewards are set by the nodes themselves.

Voting will open on July 5th. At that time, Bytom will provide an APP to facilitate voting delegates to participate. The voting rules are one vote, one vote. After voting, BTM will be locked. It will take 20 days to unlock. You can continue voting later.

The Bystack node election time plan is as follows:

3. What is the difference between Bystack and the BaaS platforms of IBM, Microsoft Azure and Amazon AWS?

Different architectures: At present, most BaaS are based on alliance chains, private chains, and some are based on Ethereum, which are neither independent nor controllable. Bystack is the first BaaS with a single-master multi-side architecture, which is autonomous and controllable. It is difficult for a single public chain or a single alliance chain solution to meet specific business needs.

For example, certain business scenarios require irreversibility of transactions and non-tamperability of data, which cannot be achieved by the alliance chain. Certain scenarios have very high requirements for transaction speed and TPS, and the enterprise version of public chains such as Ethereum cannot meet these requirements.

The implementation scenarios are different: The current implementation directions of other BaaS are mostly non-mainstream business fields such as certificate depository, public welfare, charity, traceability, etc. After all, blockchain is a subversion of traditional business logic and technical logic. They are For those who are successful on the Internet, the success of the Internet is the disadvantage of blockchain.

For example, they cannot decentralize data, computing, or account identities. Therefore, there is a paradox of self-subversion when traditional giants do blockchain. Although the Bystack white paperA dozen business application scenarios are listed, but the focus will be on one or two scenarios with a market potential of hundreds of billions.

『三』What is the blockchain BaaS platform

As blockchain technology continues to be applied in the physical field, more and more technology companies have proposed their own underlying technology frameworks. As well as industry solutions in vertical fields,
The English name of the BaaS platform is Blockchain as a Service, and the direct translation is Blockchain as a Service, referred to as BaaS. In fact, BaaS is a new type of cloud service that combines blockchain technology, which refers to embedding the blockchain framework into the cloud computing platform.
Blockchain as a Service BaaS is a space created by companies such as Microsoft and IBM from their own cloud service networks to run a certain blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of BaaS nodes is to quickly establish the development environment you need and provide a series of operational services such as blockchain-based search queries, transaction submissions, and data analysis. These services can both It is centralized or decentralized, and is used to help developers verify their concepts and models faster. The serviceability of BaaS nodes is reflected in: stronger tools, making it easier to create, deploy, run and monitor blockchains.
The main technical features include:
Fast service construction: a multi-mode distributed ledger platform to facilitate the rapid construction of services;
Visual operation and maintenance management: providing visual operation and maintenance from the network, system and business levels Operation and maintenance management;
Comprehensive regulatory audit: Provide comprehensive monitoring and audit support to meet business compliance needs;
Smart contract management: Support programmable contract development and provide standardized contract templates;
Blockchain as a Service: Provides configurable enterprise-level blockchain cloud services for various industries;

The BaaS platform is easy to access, highly available, efficient and stable, safe and reliable, highly compatible, Personalized customization, intelligent operation and maintenance and other features. Currently, the blockchain service platform Baas has supported the implementation of multiple blockchain products and projects, such as commodity traceability systems, genealogy chains, etc.

The professional base is based on providing students with diversified growth paths, promoting the reform of the training model integrating professional degree research, production, and research, and building an applied and compound talent training system.

『四』What is the difference between public cloud and private cloud

Public cloud is a cloud that third-party provider users can use. Public cloud is generally available through the Internet and may be free. Or low cost.
Private cloud refers to the cloud used by the enterprise itself. All its services are notNot for use by others, but for internal use by your own personnel or affiliates. The deployment of private cloud is more suitable for large enterprises or government departments with many branches. As these large enterprise data centers become centralized, private cloud will become the mainstream model for deploying IT systems.
To put it simply: the private cloud is your own home, where only you or the people you allow can live. Generally, the privacy you don’t want outsiders to know is kept at home; the public cloud is a paid attraction, and everyone who has bought a ticket can Can enter.

The difference between public cloud and private cloud
Location of IT facilities: When an enterprise builds a private cloud platform, the IT infrastructure is its own and is generally located within the enterprise. When using a public cloud platform, the IT infrastructure is located in a third-party data center. There is an exception here, which is the concept of virtual private cloud (VPC, Virtual Private Cloud) proposed by some service providers. It refers to a dedicated computing environment isolated by technical means within a third-party data center, and Connect to the enterprise through secure channels.
Infrastructure differences: For many large enterprises, due to years of IT construction and technological evolution, their IT infrastructure often uses different technologies and platforms. In other words, these enterprises use heterogeneous platform environment. However, for most current public cloud service providers, their platforms are often built on cheap and standard hardware platforms. Platforms built in these standardized ways can meet the needs of most users at a relatively good price/performance ratio. In addition, in terms of service provision, public cloud service providers often provide the most popular services with the most extensive and concentrated demand. Therefore, for public cloud services, the services and environment are often isomorphic, which is different from the IT environment built by the enterprise.
Business model: If an enterprise chooses to build its own IT system, it will obviously need to make a large one-time investment to purchase software and hardware equipment, and even the infrastructure of a data center. In the company's financial statements, this is reflected as a relatively large fixed cost. However, if an enterprise uses a public cloud service provided by a third party, then according to the current charging method of cloud computing services, the enterprise can choose to pay by monthly service fee or by the amount of IT resource usage. In this way, enterprises can use IT services without a large upfront investment, which is reflected in an ongoing operating cost.
Differences in degree of control: The IT system built by the enterprise itself is completely owned by the enterprise as an enterprise asset and is operated and maintained by the enterprise itself. Although enterprises need their own IT operation and maintenance teams, the advantage is that enterprises can independently control IT systems and carry out transformation and customization according to actual needs. For public cloud services, enterprises actually adopt the method of renting services. The advantage is that they do not need to manage the basic platform services themselves, but for enterprises this also reduces their customization.capabilities, because all infrastructure, including servers, networks, storage, etc., as well as the above software platforms are maintained and managed by service providers.

『五』 Is the enterprise-level blockchain cloud service platform BaaS?

In many cases of blockchain commercial applications, we can always see the word BaaS, BaaS It is the abbreviation of Blockchain as a Service, and the Chinese translation is "Blockchain as a Service". So what exactly is Blockchain as a Service BaaS?
With this question, we followed Xiao Wang from the Renren blockchain technology team to discuss it carefully.
According to Xiao Wang: Blockchain as a Service BaaS is a concept mainly proposed by the two giants Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service that combines blockchain technology. . For example, Microsoft's Azure cloud computing platform and IBM's Bluemix Garage cloud platform both provide blockchain as a service BaaS.
Blockchain as a Service BaaS is a space created by companies such as Microsoft and IBM from their own cloud service networks to run a certain blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of BaaS nodes is to quickly establish the development environment you need and provide a series of operational services such as blockchain-based search queries, transaction submissions, and data analysis. These services can both It is centralized or decentralized, and is used to help developers verify their concepts and models faster. The serviceability of BaaS nodes is reflected in: stronger tools, making it easier to create, deploy, run and monitor blockchains.

『Lu』Microsoft, Hyperledger and the United Nations join the Blockchain Identity Alliance ID 2020

Technology giant Microsoft and the blockchain alliance Hyperledger have joined the blockchain-based identity alliance ID 2020. Chain’s digital identity project—ID2020 Alliance.

The news was announced yesterday at the World Economic Forum in Davos, Switzerland, and the ID2020 alliance - which has also been joined by aid agency Mercy Corps and the United Nations International Computing Center - aims to provide Digital identity to improve people’s lives.

According to a press release, the group is developing solutions focused on giving users direct ownership and control of their personal data through the use of blockchain technology. The focus of the problem is that there are more than 1.1 billion people around the world who cannot prove their identity and therefore have difficulty accessing benefits and services. According to the World Bank, this situation also raises more serious issues such as human trafficking.

The project has received a $1 million donation from Microsoft, as well as funding from Accenture and the Rockefeller Foundation.ckefeller Foundation) and other entities. Global consulting giant Accenture, one of the project's founding members, announced a $1 million investment last summer at the ID 2020 Alliance Summit in New York.

David Treat, general manager of Accenture’s global blockchain practice, said:

Decentralized, user-controlled digital identities have the potential to help refugees and other disadvantaged people unlock The potential for economic opportunity while improving the lives of those who just want to browse the web safely and privately.

The press release also explains that the digital identity owned by the user will include a legal form of government-issued identification and allow for seamless authentication of individuals and institutions.

『撒』 Is the enterprise-level blockchain cloud service platform BaaS?

BaaS is the same as IaaS, PaaS and other concepts, and tends to be within the scope of public cloud, while enterprises Services should consider more customized needs. Based on many years of practical experience from enterprise users, ChainNova is building solutions from both public cloud and hybrid cloud (i.e., enterprise cloud services). Currently, well-known domestic and foreign cloud service providers such as AWS are preparing to launch systematic service solutions, hoping to bring more flexible, complete, and powerful technical capabilities to customers. The purpose of establishing such a blockchain technology capability platform and the smart chain ChainNova is of course to better help customers solve problems. In the financial field, ChainNova is cooperating with industry leaders such as IBM to jointly create end-to-end industry solutions with the help of both parties' rich experience in financial industry scenarios.

『八』Microsoft Accelerator CEO Tan Lin: Optimistic about public chains in the long term, but ToB business may be the first to be implemented

The above poem is the work of Xiaobing, the artificial intelligence developed by Microsoft, and she One of my favorite poems from the collection of poems "Sunshine Lost the Window".

3 days ago, I saw Xiaobing again in the Microsoft Asia-Pacific R&D Group. When I approached her, Xiaobing scored 78 points on my appearance through the real-time sensory platform, which was higher than half a year ago. The previous 67 points have improved. It seems that this guy has learned wisely.

Of course, the purpose of my trip is not Xiaobing, but to interview Tan Lin, CEO of Microsoft Accelerator Beijing. He has more than 20 years of experience in IT companies. He has served as a researcher at Peking University Smart City Research Center, general manager of CA Greater China, BI/EPM channel director of Oracle Greater China, marketing director of Apple China, etc., and in February 2018 Appointed CEO of Microsoft Accelerator·Beijing.

Microsoft Accelerator is known as "the selection rate does not exceed 2%, which is more difficult to get into than Harvard", but after sorting out the past 13 batches of BeijingAfter reviewing the list of innovative companies in Beijing, I found that there were many blockchain companies among them, including Qulian Technology, Bubi Technology, Ganrong Internet of Things, Xiaoyi, Fada, etc. Interestingly, Tan Lin himself is also very concerned about blockchain technology. He once said in an interview with the media: "The large-scale application of blockchain can break through the dimensions of traditional Internet ecological cluster companies in the next 5 to 10 years."< /p>

What are the selection criteria for Microsoft Accelerator? What kind of blockchain projects are likely to gain traction? How does Tan Lin view the current development of the blockchain industry? How should we cope with the wave of technology?

I believe that everyone can find the answers to the above questions in this interview.

Babbitt: Can you disclose the selection criteria for Microsoft Accelerator?

Babbitt: As far as we know, Microsoft Accelerator Beijing will fully implement the "360 Ecological Plan" starting from the 12th phase. Can you briefly introduce it?

Babbitt: What do you think of blockchain technology? Is it one of those exponential technologies you mentioned?

Babbitt: Which one represents the future development direction more, the alliance chain or the public chain?

Babbitt: How do you understand the token economy? What do you think of its financial attributes?

Babbitt: Microsoft Accelerator • Blockchain projects that Beijing has invested in include Bubi Technology, Qulian Technology, Senrong Internet of Things, Xiaoyi, Fada, and Xiubao Technology, and has invested in the above companies. What's the logic? How to get accepted into Microsoft Accelerator?

Babbitt: In August last year, the Global Tourism Blockchain Laboratory jointly initiated by Datang Network, Microsoft Accelerator, Beijing Smart City Research Institute, and Xishan Angels Association was established. Can you introduce this? What does it do?

Babbitt: Finally, let’s talk about something light and interesting. I found out that you have a hidden identity and you are a poet. You will compose a poem at each accelerator’s welcome meeting for companies settled there. , there are both ancient poems and modern poems. Why do you like to write poems?

Babbitt: Your job is to constantly pay attention to the development of various technological waves, but we know that this does not happen overnight. For example, artificial intelligence has taken so many years to achieve today's results. As ordinary individuals involved, how should we view our role and the value we play?

After the interview, Tan Lin gave me a book, "Computing the Future" co-written by Microsoft President Shi Bode and Microsoft Global Executive Vice President Shun Xiangyang. On the way back, I read it In the preface, it reads: "All of this brings us to an extremely important conclusion, just as Steve Jobs repeatedly emphasized during his lifetime - to make engineering technology and humanities compatible.combined with each other. "I think this is probably what Tan Lin wants to express in the end.

Although this paragraph is actually based on thinking about artificial intelligence technology, at the current stage of blockchain, it seems that it is not yet We need to worry about the hidden dangers it may cause, but when I think about the big names in the industry preaching about blockchain technology, they claim that it can protect the privacy and ownership of user data, and solve problems such as unfair distribution of benefits. I sincerely hope It can maintain its original intention of serving mankind and will not, as Mr. He Baohong predicted, "technology in adulthood will become what it originally hated."
