Blockchain mode enterprise chain

2. There are still many domestic enterprises that are actually doing blockchain technology, such as fun chain technology, Vientiane blockchain, energy chain group, complex US technology, Xinghe blockchain, Zhigui technology and medical chain group. They are all well-known enterprises with good technology in the instry. Internet giants basically have blockchain sections.

3. The market is roughly divided into
1. The underlying chain platform providers, such as ant / network, usually only provide chain and development tools, but the specific instry / scenario solutions and development delivery capabilities are limited, which is not their focus. They want to use blockchain packaging to sell more cloud services
2. Blockchain solution companies usually provide blockchain solutions in their own familiar fields, but most of them are small and medium-sized teams or start-up teams. Most of them have little difference in blockchain technology capabilities and have a deep understanding of their respective fields
however, the biggest problem for such companies is that because the blockchain instry is still in its early stage and there is no mature business model or profit model, most of them need external investment to continue their life, which leads to the difficulty in guaranteeing their service ability or continuous performance ability, and frankly speaking, their business is unstable
on the other hand, because it is not a professional end-to-end delivery or professional outsourcing, it has no mature methods, team and project management to ensure the efficient and complete delivery of a blockchain solution. So for buyers, it is easy to get out of control in the process of project development, or it is difficult to get satisfactory delivery results in the end.

Blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum

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. In essence, it is a decentralized 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 a batch of bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:

1. The blockchain with the whole network open and without user authorization mechanism is called public chain

2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain

3. All the nodes in the network are in the hands of one organization, which is called private chain

alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain

blockchain 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. Decentralization is the most prominent and essential feature of blockchain

2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in 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, so the information of the whole system is highly transparent

3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), 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

5. In many cases of blockchain enterprise application, we can always see the word baas. Baas is the abbreviation of blockchain as a service, which is translated into "blockchain as a service" in Chinese. So what is blockchain as a service baas? With this question, we will follow Xiao Wang of Renren blockchain technology team to discuss it carefully
according to Xiao Wang, the concept of blockchain as a service (baas) is mainly proposed by Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service combined with blockchain technology. For example, Microsoft's azure cloud computing platform and IBM's bluemix garage cloud platform all provide blockchain as a service baas
blockchain as a service (baas) is a space created by enterprises such as Microsoft and IBM from their own cloud service network to run a blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of baas nodes is to quickly establish the development environment they need, and provide a series of operation services based on blockchain, such as search query, transaction submission, data analysis, etc. these services can be centralized or decentralized to help developers verify their concepts and models faster. The service of baas node is reflected in: it is more instrumental and easy to create, deploy, run and monitor blockchain.

6. I'd like to know about blockchain. It's said that blockchain can create ten times the value of the Internet, so I'd like to ask you to use blockchain to create 1 million value for me. Anyway, it's just a small amount of money for blockchain.

7. In many cases of blockchain commercial application, we can always see the word baas. Baas is the abbreviation of blockchain

8. In a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography

broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing paradigm to program and manipulate data by using smart contracts composed of automated script code
