Blockchain and public security work
There is no doubt that blockchain has development prospects, and the necessary condition for development prospects is to enter the mainstream market
North America blockchain infrastructure the oan (former aion network) founder and CEO Matt spoke published an article entitled "in order to successfully enter the mainstream market, blockchain projects must" eat dog food "in Forbes on July 24, in which Matt mentioned his views on how blockchain should enter the mainstream market - & quot; Eat dog food
in the science and technology circle, there is a jargon called & quot; Eat dog food Dogfood (also known as eating your own dog food) refers to companies using their own procts and becoming users of their own procts. Many high growth companies (such as Microsoft, Facebook, Amazon, apple, Netflix and Google) also test their procts by "eating dog food" or help build credibility“ "Eat dog food" is often used to find and fix bugs, but it has another value: to create reliable use cases for the company's procts
this is worth learning from blockchain projects, because blockchain projects often hold & quot; Once built, they (users) will come naturally, which habitually leaves the responsibility of creating new and interesting blockchain applications to a third party
this attitude is very common, even the well-known blockchain summit consensus 2019 also held a conference entitled & quot; Once built, they (users) will naturally come: to build a global blockchain Center & quot; To discuss how governments around the world can make efforts to attract blockchain projects while balancing regulatory, investment and innovation needs
to be fair, this strategy may be effective for blockchains that only focus on people in the currency circle. For the security token, especially for the exchange represented by the transaction, it makes more sense - "supply creates demand" is the usual idea here, especially considering that the realization of these transactions requires the construction of complex infrastructure
in contrast, "eat dog food" is more likely to be adopted by blockchain project developers who seek mainstream audiences (such as those in financial instry, manufacturing and supply chain, identity management, etc.). If blockchain technology wants to enter these mainstream fields, blockchain companies must first "eat dog food". This can not only clearly prove that blockchain technology is feasible outside the coin circle, but also highlight that blockchain can not only optimize existing use cases, but also create new use cases
and the oan team has been adhering to this concept, and relying on the oan and aion's technology stack built over the years, it has developed a financial technology platform moves for independent workers
Matt said that in the development and development of moves, the team hopes that the relevant functions of the OAN blockchain network can be brought into full play, so it will focus on the following three aspects:
1. How to use the OAN blockchain network to improve the credit efficiency of the proct there are two main considerations to improve credit efficiency: 1) can we use the mechanism of the defi market to rece the cost of capital; 2) Can the blockchain technology be used to increase the external trust in the credit process of moves. Here, moves will form a mechanism of "pooling wisdom", so that everyone can contribute to recing credit risk and increasing the credibility of credit process, and may even develop a micro guarantee mechanism in the future. Therefore, users will be able to participate in the market established by the platform as borrowers, lenders or guarantors
specifically, by connecting moves with the oan network, and with the help of digital asset aion, a relationship of interest consistency is formed between procts and users, so that users can personally experience the success of moves procts and directly participate in the oan, a blockchain network supporting moves
3. How to create the first open system of financial reputation data with moves
this open system may become a substitute for traditional credit scores or related mechanisms. Over the years, banks and financial institutions have been using Equifax, Fico or other similar institutions' scores as risk indicators, and the moves team believes that the procts they are building will be a good start - the beginning of a more perfect and modern financial reputation system. This is a long-term goal
moves supports North American mainstream carpooling, take out and other casual work economic platforms, and will be the flagship open application developed by the oan on its blockchain network. In June, moves expanded its operations from Ontario to Alberta and British Columbia into western Canada
all the initiatives of the oan team adhere to the spirit of "eating dog food" and strive to make blockchain technology enter the mainstream market as soon as possible. Blockchain is not for the minority, but for the mainstream. In addition to the oan team, many projects and institutions in the blockchain instry are also aiming at this goal. Can you say that such an excellent and targeted blockchain has no development prospects
However, where are the opportunities for these innocent employees? To put it bluntly, some blockchain entrepreneurs are bent on "empty handed White Wolf", and exploit layer upon layer through "deception". Using asymmetric instry information, blockchain, digital currency and other projects are over packaged, giving people a sense of "Hope". This part of the blockchain entrepreneurs' inherent "bad root", to a certain extent, has led to the instry's "sick" development trend
some blockchain entrepreneurs call for embracing the times, changes and the future, emphasizing the charm of decentralized "fairness". But in reality, it is for self-interest, which hurts the interests of job seekers and other related groups, which is a great injustice in itself
The asymmetry of information is not permanent. Blockchain, digital currency and so on are all areas worthy of attention, but they are not the capital that can be used by some entrepreneurs as unlimited squanders all the time. For the job seekers who want to join them, they should polish their eyes, otherwise they may be surprised if they are not carefulblockchain is composed of a series of data blocks generated by cryptographic methods. Each block contains the hash value of the previous block, which is connected to the current block from the original block to form a blockchain.
At present, blockchain is not only applied in the financial instry, but also in the following instries, such as banking, payment and cash transaction, network security, academic records and academia, election, network and Internet of things, prediction, right and so on. There are still many areas that need blockchain technology. It can be imagined that the Internet + we mentioned before will become a blockchain + situation in the future
from the demand side, finance, health care, notarization, communication, supply chain, domain name, voting and other fields are beginning to realize the importance of blockchain and try to connect technology with the real society
from the perspective of the investment side, the supply of investment funds for blockchain is graally rising, the investment enthusiasm of venture capital is also rising, and the investment density is increasing. The supply of funds at the supply side is expected to promote the further development of technology
from the perspective of market application, blockchain can become a market tool to help the society rece the cost of the platform and make the intermediary institutions become the past; Blockchain will promote the shift of the focus of the company's existing business model, which is expected to accelerate the development of the company
from the perspective of underlying technology, blockchain is expected to promote the transformation of data recording, data dissemination and data storage management; Blockchain itself is more like an open source protocol at the bottom of the Internet, which will touch or even completely replace the underlying basic protocol of the existing Internet in the near future
from the perspective of social structure, blockchain technology is expected to integrate law and economy and completely subvert the original social supervision mode; Organizational form will change because of it, and blockchain may eventually lead people to a distributed and autonomous society
Where should we start to learn blockchain
first of all, we need to have a comprehensive understanding of the source and cognition of blockchain from a macro perspective. Why do we need to do this? Because if we don't understand, we will have no voice. We don't know how to judge that the next outlet is blockchain. Even if people follow suit, we also need our own learning solution as support. So, what do we need to know? I have listed the contents, For your reference only, if you already know something about it, you can skip this step:
1), basic theory of blockchain
2), basic programming (computer software and hardware foundation, character set and character encoding, HTML5 + CSS3 and other front-end technologies, ECMAScript + BOM + DOM, jQuery, node.js, Ajax and express framework)
3) Go programming language and database operation
4), blockchain 1.0 programming - bitcoin
5), blockchain 2.0 - Ethereum
6), Star Cloud chain and EOS development practice
7), blockchain 3.0 - fabric of super ledger
to you who are still struggling in the tuyere of blockchain: there is a market when there is demand, and the society never lacks excellent technical talents, After a good understanding (you can refer to Qianfeng's blockchain video tutorial), you must be firm and accurate
1. POW workload proof, which is familiar with mining, calculates a random number that meets the rules through and or operation, that is, obtains the bookkeeping right, sends out the data that needs to be recorded in this round, and stores it together with other nodes in the whole network after verification
advantages: complete decentralization, free access of nodes
disadvantages: bitcoin has attracted most of the computing power in the world, and other blockchain applications using POW consensus mechanism are difficult to obtain the same computing power to ensure their own security; Mining causes a lot of waste of resources; The period of reaching consensus is long, which is not suitable for commercial application.
2. Proof of rights and interests of POS, a mechanism of upgrading consensus of pow; According to the token proportion and time of each node; It can rece the difficulty of mining in equal proportion, so as to speed up the speed of finding random numbers< Advantages: to a certain extent, it shortens the time to reach a consensus
disadvantages: mining is still needed, which does not solve the pain point of commercial application in essence
3. Dpos share authorization certification mechanism is similar to the voting of the board of directors, in which the coin holders cast a certain number of nodes to verify and account on their behalf
advantages: greatly rece the number of participating verification and accounting nodes, which can achieve second level consensus verification
disadvantages: the whole consensus mechanism still depends on token, and many commercial applications do not need token to exist
4. Pool verification pool, which is based on traditional distributed consistency technology and data verification mechanism; It is a consensus mechanism widely used in the instry chain at present.
advantages: it can work without token, and realizes second level consensus verification on the basis of mature distributed consistency algorithms (pasox and raft)
disadvantages: the degree of decentralization is not as good as that of bictin; The multi center business model is more suitable for multi-party participation
it has great advantages in using consensus mechanism to ensure data consistency (the consensus mechanism is first proposed by ripple, and the network transaction synchronization mechanism with data correctness priority. In the consensus network, no matter how the software code changes, if you can't reach a consensus, you can't enter the network, let alone fork)
- - - - - - - -
PS: a little black, although the consensus mechanism can absolutely ensure that there will be no hard bifurcation at any time. However, the disadvantage of this mechanism is obvious, that is, it is much longer than the current bitcoin network to reach a consensus with other nodes. In extreme cases, the consequences of disconnection in ripple consensus mechanism network are also very terrible
it is possible that one day after the power failure in your home, the whole system will no longer be able to reach a consensus with other rippled nodes (in fact, the consensus mechanism requires more than 80% of the nodes to acknowledge your data before your submission will be accepted by other nodes, otherwise it will be rejected by exclusive nodes), Even you can only empty all your 500 GB data and resynchronize to connect to other ripple nodes
so at present, the existing rippled end is not suitable for civil use (if it is commercial, the impact is relatively small. For example, RL's own rippled node is hosted in Amazon cloud data center. If it has no response for a long time, it can make high claims, and there is almost no break in that place except for large disasters). This is one of the aspects RL has always wanted to improve.
1、 Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies
blockchain is an important concept of bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
2. Application
1. Art instry
ascribe enables artists to declare ownership by using blockchain technology, issue numbered and limited edition works, and target at any type of digital form of art. It even includes a trading market where artists can buy and sell through their websites without any intermediary services
In recent years, bitproof is the most advanced application in many document time stamp applications, which will make the traditional notarization method become the past. Bitproof offers more services than free versions including blocksgin and originstaemp, including one for intellectual property. Interestingly, bitproof recently cooperated with an it school in San Francisco to put their students' academic certificates on the blockchain, completely redefining how to handle and use diplomas and student certificates Development instry colu is the first enterprise to allow other enterprises to issue digital assets. They can "token" all kinds of assets to impress many people. Although the free bitcoin wallet couperparty also allows simple tokens to be issued and traded among other wallet holders, the tokens of colu can be set with various states and types, can be detached from or returned to the system, and can be stored on BitTorrent's network when the data stored on the blockchain is too large4. Real estate instry
they plan to make the whole instry chain process more modern and solve various problems faced by everyone when participating in real estate, including naming process, land registration, agency, etc
5, Internet of things
a possible application scenario is: generate corresponding behavior through transaction, assign address to each device, inject a certain fee into the address, and perform relevant actions, so as to achieve the application of Internet of things. Similar to: PM2.5 monitoring point data acquisition, server leasing, webcam data call, DNS server, etc
6. Insurance instry in the past two years, the hottest topic in the field of science and technology can not be separated from blockchain technology. This underlying technology, born out of bitcoin, has proved its highly secure and reliable architecture and algorithm design with more than seven years of stable operation. At the same time, with innovative technologies such as distributed ledger and smart contract, it has opened up a huge imagination space for instrial upgrading of many instries. Some instry experts even predict that blockchain technology will set off the second Internet revolution
extended materials:
in 2008, Nakamoto proposed the concept of "blockchain" in the white paper on bitcoin, and established bitcoin network in 2009, developing the first block, namely "Genesis block"
the shared value system of blockchain was first imitated by many cryptocurrencies, and improved in workload proof and algorithm, such as equity proof and scrypt algorithm. Subsequently, the blockchain ecosystem has been evolving all over the world, with the emergence of ICO for the first token sale, Ethereum for smart contract blockchain, "asset token sharing economy with light ownership and heavy right to use" and blockchain countries
at present, people are using this shared value system to develop decentralized applications (DAPP) in all walks of life, and build decentralized autonomous organizations and decentralized autonomous communities (DAS) around the world

enhance the judicial effectiveness of notarization
the core value of notarization is that the evidence effect of notarization must be authoritative and can be accepted by judicial institutions, which requires it to have sufficient guarantee in terms of authenticity, and blockchain notarization can provide sufficient guarantee in this aspect
the network account book of the blockchain adopts the distributed storage accounting mode, and is equipped with the technologies such as permission system configuration, multi-level encryption mechanism, partition consensus protection mechanism, and timestamp to ensure the authenticity and integrity of the data. After the formation of notarized documents, once a series of actions such as uploading the blockchain and stamping the time stamp are completed, the file data recorded on the chain will be extremely difficult to tamper with. No matter when and who registers the file content, it has the complete sense of uniqueness and traceability, which greatly improves the effectiveness of notarized judicial evidence<

improve the efficiency of notarization work
cumbersome evidence confirmation process, a large number of manual audit cost investment, has been a huge problem faced by the notarization instry, the blockchain certificate can effectively solve this problem
through face recognition, live detection, electronic signature and other artificial intelligence technologies, blockchain notarization can directly connect with the latest data source of the public security information database, and then conct comparison and recognition to quickly confirm the identity of the parties. The hardware acceleration of blockchain notarization, such as GPU / FPGA, 10000 level smart contract sandbox TPS and other intelligent auxiliary systems, can help the notary office to process notarial certificate generation, execution certificate generation, intelligent query and other operations in seconds, which effectively solves the tedious and time-consuming problems of evidence solidification and preservation process, and greatly improves the efficiency of notaries' business, At the same time, it can also effectively avoid manual errors and other problems

broaden the boundary of notarization business
with the improvement of work efficiency, the notary office can free up more human and material resources to expand the scope of notarization business in Xinjiang. In the era of digital economy, almost all transactions and payments are completed online, which will proce many new notarization needs. Of course, notarization institutions should move from time to time to provide corresponding notarization services for citizens in the digital era
although the blockchain technology is still in its infancy in China and even in the world, it has been recognized by most people that it will be the infrastructure of the next generation of digital era. I believe that in the near future, the data on the blockchain will achieve massive growth, which is undoubtedly a huge and valuable data resource library for notarization, and it is also a blue ocean for the market. Therefore, whoever gets the ticket of blockchain notarization earlier will gain the leading power in the era of digital notarization, and then continue to expand the scope of notarization service in Xinjiang

deepen the inherent value of notarization
in addition, the emergence of blockchain notarization certificate has also brought changes to the business connotation of notarization institutions. First, the emergence of the public certificate of blockchain expands the single practice mode of notarization institutions to carry out practice activities through notarization intelligent platform; Second, the emergence of blockchain notarization makes notarization develop from the traditional independent practice of notarization institutions to the practice of interaction and cooperation between notarization institutions and technology companies, judicial institutions and even parties; Thirdly, the process of block chain notarization has changed from passive evidence preservation notarization to active evidence preservation. The notarization function has been extended to maximize the value of dispute prevention of notarization.
