1. blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
blockchain is the underlying technology of bitcoin, like a database ledger, recording all transaction records. Because of its safety and convenience, this technology has graally attracted the attention of the banking and financial instry
in April 2018, a group of scholars from Oxford University announced the establishment of Woolf University, the world's first blockchain University
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing method, 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.

2. First of all, we can take a look at the official website explanation of blockchain technology. 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 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
as we all know, blockchain technology is an independent underlying architecture from bitcoin system. From the perspective of architecture model, it is a set of distributed ledger, which is naturally used for bookkeeping
in the blockchain technology, if you want to generate accounting records, you need to have the transaction and flow of funds. Therefore, in the initial blockchain technology, the cryptocurrency corresponding to the main network is used as circulation goods, and the circulation transaction records of cryptocurrency between the accounts of the main network of the blockchain will be recorded on the main network
different from other transaction record databases, transaction records on the main network of blockchain technology will be recorded on all block nodes (i.e. all data blocks) in the main network, which is the so-called decentralization principle. That is to say, in blockchain technology, there is no central database to store all records, Every block on the chain has the transaction data of the whole chain, that is to say, every data block is the center
another feature of blockchain technology is that it can't be tampered with, because every transaction on the blockchain will be recorded in all blocks on the chain, so no single data block can change the record. Even if you change it, all other data blocks will also record real data, and each group of data can be traced back to the first time
because of these characteristics of blockchain technology, after the advent of bitcoin, blockchain has also attracted a lot of attention, and many people also began to want to use blockchain technology to make a centerless, traceable and unchangeable data, so as to ensure the credibility of the data
however, blockchain technology also faces many problems, such as single application scenario, non modifiable original error data, non recoverable currency stolen by hackers, etc.

4. The underlying architecture of laikelib blockchain technology is a blockchain technology system developed by the blockchain Technology Laboratory of Shanghai Heshu Software Co., Ltd. for details, you can go to the official website of laikelib.
5. Hello, it's a great honor to be here to answer your question. The following are some of my views on this issue. If there are any mistakes, please point them out. 1. The so-called blockchain technology, also known as the distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in database records
2. Blockchain is an innovative application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies in the Internet era. In recent years, the development and application of blockchain is of great significance to technological innovation and instrial revolution. This experience introces the relevant knowledge of blockchain technology
3. Blockchain is a distributed ledger, which can contain financial and / or non-financial transactions. It can be replicated (distributed) on multiple systems in almost real time through peer-to-peer network. Each participant "owns" the same ledger and gets updated when adding any transaction. Each participant helps to determine the inherent "invariance" of all existing records, Using cryptography and digital signature to prove identity, authenticity and enforce read / write access, there is a mechanism that makes it difficult to change history, and it is easy to detect someone trying to change it. Thank you very much for your patience. If you have any help, please accept it. I wish you a happy life! thank you!

6. The English version of blockchain is to introce the blockchain information in English
blockchain is a kind of distributed shared accounting technology. What it needs to do is to enable all parties involved to establish a trust relationship at the technical level. Blockchain can be roughly divided into two levels, one is to do the underlying technology of blockchain; The second is to do the upper application of blockchain, that is, the transformation, optimization or innovative application based on blockchain. What is the core meaning of the blockchain? Our understanding is that the core meaning of the blockchain is to establish data credit between the participants, create unilateral ecology under clear provisions through unilateral confrontation, and jointly guarantee complete opportunities. This is a system, and this kind of construction can end the problems before the blockchain, When data is shared, it is impossible to achieve new sharing. Even if you do orientation, it only gives you an interface. After the blockchain is established, the participants can realize credit sharing. Domestic platforms have applied blockchain technology to crowdfunding. For example, the European crowdfunding platform issues different tokens for crowdfunding projects on the platform. As an asset certificate, tokens can be freely traded in the market.

7. After that, the picture is very smooth, that is, there is a little action delay. Although the computer configuration is not high, it can still drive the dragon fly to kill, but the rest of the boss on the ground are single kill, fast 100 dog teeth trap
8. Its basic idea is: through the establishment of a group of public decentralized credit storage media on the Internet. In the communication network, users query and record the credit value data through the token, so the data information is true and can not be tampered with.
9. Before we mentioned the decentralized blockchain application platform, we always thought of foreign procts, such as Ethereum. But when I talk about this topic again today, I will think of a blockchain technology R & D enterprise in Shanghai, China --- Heshu software. Laikelib is a new generation of decentralized, independent innovation, safe and efficient, fully shared and diversified infrastructure platform for blockchain application development based on the combination of main chain and side chain technology. It can help developers quickly create decentralized applications. Similar to Ethereum in mode, they are all blockchain services, but the implementation mechanism is slightly different. The biggest feature of Ethereum is that it greatly expands the function of the script engine, and relieves the stack memory, function call depth and script length restrictions. But there is a big disadvantage that the application code itself and the data generated by the application exist in the same block chain, resulting in the rapid expansion of the chain. However, unlike several blockchain systems, its scalability is not achieved by transaction scripts, but by adding side chains. The advantage is that it reces the difficulty of contract programming, avoids the expansion of blockchain and allows each application to customize personalized block parameters.
