Key and difficult points of blockchain research
blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data. In short, in the blockchain system, the transaction data generated by each participant will be packaged into a data block after a period of time. The data blocks are arranged in chronological order to form a chain of data blocks. Each participant has the same data chain and cannot be tampered unilaterally, Any modification of information can only be carried out with the agreement of the agreed proportion of subjects, and only new information can be added, and the old information cannot be deleted or modified, so as to realize the information sharing and consistent decision-making among multiple subjects, and ensure that the identity of each subject and the transaction information between subjects can not be tampered with, open and transparent
the technical commonness of blockchain projects: block, account, smart contract and consensus, which constitute the general model of the current blockchain system
today, I want to tell you what is a real dragon ball for blockchain application landing and enabling traditional commerce and trade
first of all, dragon ball technology will develop the electronic business platform integration asset plan, and the cable asset payment facility will serve the upcoming block chain business application landing wave. In the future, valuable assets can be applied to all aspects like WeChat payment and Alipay, which will bring convenience to people's payment and life, and at the same time, increase sales to businesses. This is the commercial value brought by Longzhu. Based on Singapore, the Longzhu foundation in Singapore will radiate the world and aspire to become the leader of new asset technology and contribute to the circulation of global commodity trade
In the bear market of blockchain, how to find the real valuable blockchain projects? Xiaobian explains from the following aspects:
1. Use the blockchain security technology testing center to see if it is MLM coin or air coin
no matter how advanced the concept is and how exaggerated the slogan is, the essence of any project still depends on technology. Blockchain projects without technology are just like the emperor's new clothes, We need a mirror that reflects the emperor's new clothes - blockchain security technology testing center
As one of the important initiators of blockchain security technology testing center, Tianhe Guoyun, the provider of ulord public chain technology, provides code audit function, which is a sharp tool for blockchain security technology testing center to identify blockchain projects. Code audit is to build a knowledge base of block chain code automatic audit with the help of machine learning and artificial intelligence. It can improve the efficiency of code audit and solve the security problem of intelligent contract. Through the quality evaluation of blockchain projects, exchanges, wallets and smart contract codes, blockchain code audit can prevent digital asset security accidents, provide code revision measures, security protection deployment and other services. It is reported that in addition to automatic audit, Tianhe cloud blockchain code audit can also customize expert team projects for all-round audit to help investors identify "fake projects" to a greater extent2. Look at the team of blockchain project
the blockchain field can be regarded as a comprehensive field, involving cryptography, mathematics, economics, even social management and other disciplines. We have a reliable team. As I mentioned above, the ulord project brings together a large number of high-level R & D and operation personnel
3. It is not only the concept of stir frying, but also the application of it
there are many startups in the field of blockchain. If you want to become a few widely recognized high-quality projects, it is not feasible to just speculate on a set of concepts or theories. Only the projects with the ability of making blood and doing things on the ground are good projects
at present, DAPP ushare, an application based on ulord public chain, has been officially tested on October 15. Ushare Youxiang is the first decentralized experience value sharing platform in the world, and the first DAPP based on ulord public chain. Through the decentralized consensus mechanism, we can build an open, fair and just content evaluation system, encourage high-quality experience procers and experience sharing disseminators, and let the value of high-quality experience flow
there are nearly 100 teams and projects carrying out negotiation and cooperation with ulord public chain
4. Communities have autonomy attributes
whether communities have Dao (distributed autonomous organization) attributes, which is naturally suitable for blockchain,
about community governance. Whether it's the operation mode of the community or the organizational form of the developer community, it's actually a process from quantitative change to qualitative change. We have realized the importance of community
ulord adopts the community autonomy mode of "everyone can participate and contribute to the ecology"
we will have some new community governance modes, including the cooperation of some developers and the cooperation mode of large-scale open source community, which will be born and flourish
The incentive system mainly includes three aspects: first, participation in bookkeeping; Second, the contribution of network resources; Third, participate in community construction. As mentioned above, in the accounting part of our whole budget system, the pow + POS part accounts for 60%, the contribution level of participating in open source community code accounts for 10%, and the remaining 10% is used as an incentive for community operation. Therefore, we hope that more people can participate in the construction and promotion of ulord. We hope to build a platform, but the dividends obtained by this platform should be shared with everyone in the largest range, which is essentially different from Internet proctsBlockchain instry development trend analysis technology has broad application prospects
with the characteristics of point-to-point payment, openness and transparency, the most direct application field of blockchain technology application is payment field. However, there are many pain points in domestic ticketing instry, such as too many agent levels, rampant scalpers, selling more than one ticket, fake tickets, lack of credit, etc, It can be solved by blockchain technology. The traditional ticketing mode needs the support of centralized facilities such as the third-party ticketing platform, and the information is extremely asymmetric. The new ticketing mode based on blockchain technology can realize point-to-point transaction, and the whole process is transparent and traceable
blockchain e-ticketing platform
{rrrrrrr}
data source: the financial field of blockchain + application sorted out by prospective instry research institute is reshaping the financial instry pattern
the open and tamperable attribute of blockchain technology provides the possibility for decentralized trust mechanism,
has the potential to change the financial infrastructure. All kinds of financial assets, such as equity, bonds, bills, warehouse receipts, fund shares, etc., can be integrated into the blockchain ledger to become digital assets on the blockchain. They can be stored, transferred and traded on the blockchain, which makes them have a very broad application prospect in the financial field
by recing the cost of cross-border payment, securities trading and compliance, blockchain technology can save banks $15 billion to $20 billion a year
through the application of intelligent contract, blockchain + insurance can realize automatic claim settlement of insurance policy. Insurance institutions have high management and operation costs, and the data on the blockchain is true and reliable, which can effectively simplify the processing process of policy claims. In addition, the blockchain technology can realize the digital management of personal data, simplify information authentication, and help to trace the history of data
entertainment of blockchain + application: the development ecology of blockchain has taken shape, and the media instry may become the main beneficiary
blockchain technology can be widely used in news, games, picture right and other entertainment fields
blockchain technology will bring great changes to the underlying structure of the game and have a great impact on the current game instry. Gamers now have gatekeepers (centralized organizations) to decide prices, tax, censor users, control content, and profit from data. Through the decentralized platform, consumers can socialize and trade without mediation, providing more control and flexibility for game players in the game experience
blockchain + applied supply chain: it can improve the transparency of the supply chain, establish a new supply chain system
blockchain technology can improve the transparency, traceability and security of the supply chain, and promote a kind of trust and integrity. 1) At present, the supply chain has many disadvantages, such as long chain, many intermediate links, many interest joints, opaque and so on; 2)
the distributed bookkeeping technology of blockchain can register the transfer of goods on the ledger as a transaction, and determine the participants related to the proction chain management, as well as the proct price, date and location
2. The project side has rich experience and strong team innovation ability
nowadays, blockchain projects are springing up, but few of them are really remembered by people and have always been pushed forward. The reason is inseparable from the blockchain project side. If the project side has experience and the team has strong innovation, it is easy for the project to move forward orderly and proceed according to the plan. On the contrary, if the project side lacks experience, the blockchain project is more stagnant and in trouble. Therefore, a good team's project leader's pattern and courage are absolutely extraordinary
3. The project is graally implemented, and the hope is just ahead.
many blockchain projects now have currency issuance, which can let more people know about the project on the one hand, and also find like-minded investors to develop research projects together, so as to promote the implementation of the project. In this process, when the value is graally reflected, the price of the currency issuance will rise in a straight line, And people will have more confidence in the project< As we all know, in blockchain projects, only those projects that are ultimately implemented, solve practical problems for people and bring practical convenience are real value projects. If the project planning is not clear at the beginning and the goal is not clear, the final project may not be able to move forward and implement. On the contrary, the procts with clear planning and practical implementation are not only easy for people to accept and trust, but also can be widely promoted and implemented
5. Smooth user experience
after many investigations, the blockchain project party will finally implement the applied procts or application scenarios, which must be convenient for user experience and operation. In the later stage, for the problems raised by users, it will help users solve problems through multiple channels, so as to enhance the sense of participation and enthusiasm of users.
Blockchain is composed of a series of data blocks generated by cryptographic methods. Each block contains the hash value of the previous block, which is linked to the current block from the original block to form a blockchain. Each block must be generated after the previous block in chronological order, otherwise the hash value of the previous block is unknown. The generation of each block is supervised by the whole network, and each node has a complete of the data, forming a huge blockchain network between nodes
take the concentric mutual aid launched by Abbotts, a blockchain start-up company, as an example, each user can form a node, and each node can contribute computing power to the network, participate in bookkeeping, and enhance network security
