Is sharing a blockchain
blockchain is a shared database. Blockchain is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on
main features:
1. Decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage
2. Openness. The foundation of blockchain technology is open source. In addition to the private information of all parties to the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface
3. Independence. Based on consensus specifications and protocols, the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously
extended data
application direction:
1. Payment: for example, in terms of time, traditional cross-border remittance takes 10 minutes or several days, while blockchain cross-border remittance can achieve remittance in seconds e to decentralization. In terms of convenience, traditional cross-border remittance needs to wait until the next day after 19:00, while blockchain cross-border remittance only needs one mobile phone to realize all-weather remittance
2. Sharing medical records: the medical data blockchain sharing platform can achieve many application scenarios. Patient history data and other information can be linked, and medical history and image data can be viewed by personnel entering the system. These medical data can also be used for modeling and machine learning

first of all, blockchain is actually a centralized database or a decentralized database, and all technical units are for better maintenance of the public database. Each node keeps a of data independently. Consensus algorithm is used to achieve the data consistency of the node's account book, and cryptographic algorithm is used to ensure the data can not be tampered, and the data can not be tampered and the security of data sending and receiving; Through the script system, the expression scope of account data is expanded
secondly, financial sharing center involves a large amount of financial data. We can combine the technical characteristics of blockchain with Financial Sharing Center. Next, I will combine the technical characteristics of blockchain with Financial Sharing Center
① distributed storage is a distributed database of the blockchain, and each node keeps a of the data independently. If this is combined with the Financial Sharing Center, The users who can join the "financial data on the chain" in the financial sharing chain are equivalent to the "nodes" in the blockchain network, and each user can keep a of the financial data separately, so as to achieve the purpose of sharing
② tampering is not allowed. A very important feature of blockchain technology is that the data cannot be tampered, To ensure the security of a data in the Financial Sharing Center, we need to consider the security as long as the financial data is involved.
of course, before doing the Financial Sharing Center, you must determine your specific needs, if necessary, first write a framework of the whole project, and then find a formal blockchain development team according to the needs, To help you develop this "Financial Sharing Center", we must pay attention to that before formal cooperation is reached, don't disclose the information of your project casually, in order to prevent the same kind from being copied.
the two Internet hotspots, blockchain and sharing economy, happen to have sufficient "cooperation space". With the development from theory to practice, the instry has made a lot of bold explorations about the two, and even some challenges to the traditional business model have emerged. In this way, the sharing economy with blockchain will be a new business model and a new subversion of interpersonal relationship. I plan to invest in the blockchain instry. After all, in the Internet era, I searched Guangzhou Xuanling Technology Co., Ltd. on the Internet and looked at the webpage. They are a company engaged in software blockchain intelligent contract development. There are many development cases, and the team is also strong.
the essence of sharing economy is to share information and resources seamlessly, directly and efficiently among strangers, so as to create value beneficial to both sides. To achieve this goal, the prerequisite is to trust each other and know the root. But since they are strangers, where does mutual trust come from? As a result, platforms that provide a sense of trust and promise fulfillment emerge as the times require - airbnb, Uber and didi taxi are among the best. By building and maintaining technology platforms, they aggregate, reorganize and allocate scattered resources and demands, verify the true identities, professional qualifications and background information of suppliers and demanders, provide transaction information, payment tools and comment records, and finally facilitate the transaction between the two parties
in the future of sharing economy, we must open up the channel of mutual trust at the indivial level, and blockchain is the key to open the channel. Sharing economy model is a new business model with P2P as the center, while blockchain is an innovative digital technology that drives comprehensive P2P transactions. Both of them expose their own loopholes and risks, and have great room for improvement and a long period of improvement. Blockchain and sharing economy can be mutual partners or competitors. Whether it is an enemy or a friend depends on the attitude and perspective of the authorities - whether they should take the initiative to consolidate and strengthen their advantages by taking the initiative to embrace each other, or whether they should wait for the day of marginalization? Airbnb, the leading enterprise of sharing economy, chose the former
decent can also be regarded as a kind of sharing economy project or a blockchain project.
in practice, the representative of sharing economy, mutual insurance, part-time crowdsourcing and blockchain technology have practical applications. For example, mutual insurance platform includes crowdsourcing and zebra club, and part-time crowdsourcing platform has Haohuo. They all introce blockchain technology to make their business process easier and easier to obtain the trust of users. Interestingly, they all use the bmeng blockchain platform. It seems that the digital asset platform like bmeng will become one of the mainstream business models in the blockchain instry.
the new way of sharing economy Mavericks seems to take over the business world because of the recent arrival of blockchain technology, which futurists call "ultimate subversive". The European crowdfunding model of "blockchain + crowdfunding" has emerged in China
blockchain is an innovative technology, which helps to realize real point-to-point transactions. Its implementation is determined, verified and recorded by decentralized ledger, which is protected by encrypted hash code. Each group of operations is digitally recorded in the data block created every ten minutes, and then irreversibly sealed with a random and unique code set called "hash". This can achieve a al purpose. First of all, this ensures that data blocks can be securely sealed and transaction data is permanently stored. Secondly, the block hash constitutes the first transaction in the subsequent transaction block and becomes the link or "chain" between blocks, so it is named blockchain.
