Underlying code of blockchain Technology
Publish: 2021-05-23 15:26:24
1. The era of blockchain 1.0 is the era of digital currency, and the technical basis is:
1. Lianzhuang data block structure based on blocks
2. Network wide shared ledger
3. Asymmetric encryption
4. Source code open source
blockchain 2.0 era technical basis:
1. Smart contract; It is an application in the blockchain system. It is a business logic that can run automatically by coding. It usually has its own token and special development language
2. DAPP: it includes the user's applications, including but not limited to various cryptocurrencies, such as Ethereum wallet
3. Virtual machine: used to execute the compiled code of smart contract. Virtual machine is Turing complete
with the application and deepening of blockchain technology, the era of blockchain 3.0 has come. The mode of blockchain cooperation can be seen from behind the operation of all walks of life. Therefore, blockchain will change the way of human life widely and profoundly, so the whole life service will enter the era of blockchain. In the process of Internet development, blockchain + physical instry, blockchain e-commerce and blockchain community operation can be applied to blockchain technology
of course, 3.0 came into being with the development of modern cryptography. Today's applied cryptography is the result of cryptography 20 years ago. Therefore, in order to apply blockchain technology to more participation scenarios, especially in Internet economy and other aspects, more verification is needed to verify whether the existing encryption technology can meet the demand, and more in-depth integration of cryptographic frontier technology and continuous innovation are needed.

2. The projects of jinwowo network technology analysis blockchain are divided into three levels:
the top and easiest thing to do is the application layer. I can see two or three such projects every day, accounting for more than 95% of the whole market. But such companies often write a lot of technical things in the white paper. In fact, they also write in vain. This is purely for the purpose of collecting pages, because they don't need to talk about technology at all
the second type is the intermediate operation level, such as quantum chain and ant. This kind of project is similar to the operation procere, called the basic chain, which is used to run the application. This category is relatively small, and the proportion has dropped to less than 5%
the third category is more downward extension and lower level, such as standard chain and arcblock. This kind is even less. It's good to see two or three in a month. And some of them are not necessarily true, because there is really nothing to write about, and all fields are occupied by others, so someone will go in this direction.

3. 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 for building trust and acquiring rights and interests between different nodes in the blockchain system.
blockchain is an important concept of bitcoin, which is essentially a decentralized database and serves as the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chained 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 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 A new distributed infrastructure and computing method for programming and operating data by using intelligent contract composed of automated script code
go language + blockchain training course:
1 What are the advantages of go
advantages of go
1: performance
2: language performance is very important
3: developer efficiency & don't be too innovative
4: concurrency & Channel
5: fast compile time
6: team building ability
7: powerful ecosystem
8: gofmt, Mandatory code format
9: grpc and protocol buffers
can be directly compiled into machine code, independent of other libraries. Glibc version has certain requirements, and deployment is completed by throwing a file
static type language has the feeling of dynamic language. Static type language can check out most hidden problems when compiling, while dynamic language has the feeling that there are many packages that can be used and the efficiency of writing is very high.

4. Laikelib main chain: the main chain of laikelib mainly deals with the interaction between the application business model and the application scenario. Laikelib side chain: around the main chain, any application system can be developed in the side chain for users to use.
5. Comprehensive interpretation of blockchain
with the popularity of bitcoin, many investors also aim at the technical support behind bitcoin blockchain. So, what is blockchain? In fact, it is a decentralized distributed ledger database. Without the center, each node of data storage will the whole ledger synchronously, and the information is transparent and difficult to tamper with.

7. 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.
