Blockchain development process
1.Requirement analysis:Determine the specific requirements and goals of blockchain applications,design an executable development plan,and determine factors such as budget and time.
2.Design and implementation:Determine the blockchain system architecture based on requirements,including node construction,selection of consensus mechanisms,determination of data storage methods,and so on.
3.Decentralized contract:The smart contract of blockchain is one of its important applications.Developers can create and run smart contracts on the blockchain to achieve common functions such as automated transactions,data writing,and data querying.Therefore,smart contracts should be designed and deployed on the blockchain.
4.System testing and security inspection:Conduct system testing and security inspection,and repair and improve all system vulnerabilities.
5.Online maintenance:Deploy and operate blockchain,continuously improve the system,promote,iterate,and update blockchain applications
What is a public chain?
Public Blockchain refers to a fully open blockchain network that does not require access rights and can be joined and used by anyone.The public chain adopts a completely open consensus mechanism,such as PoW,which means that anyone can participate in the maintenance and confirmation mechanism of the network.At the same time,through the decentralized services provided by the underlying public chain,it achieves the characteristics of openness,transparency,tamper resistance,and difficulty in being attacked for data such as digital currency,transactions,and asset certificates.
The process of building a public chain
The construction of a public chain can be simply summarized from a technical perspective as follows:building the underlying architecture of blockchain->consensus mechanism->smart contract and token issuance.In terms of underlying architecture,the public chain generally adopts the underlying design of networks such as Bitcoin and Ethereum,and pays attention to the stability,security,and scalability of the network.The following is the specific process:
Step 1:Choose a development language and blockchain architecture
Choosing the appropriate development language and blockchain architecture is crucial as it will determine the security,stability,efficiency,and scalability of the public chain.At present,when developing public chains,the mainstream languages are mainly C++,Rust,and Go,and in terms of blockchain architecture,the forms represented by Bitcoin and Ethereum have become the standards for the underlying architecture.
Step 2:Choose a consensus mechanism
The consensus mechanism is the most crucial part of the public chain,serving as the foundation for formulating and confirming all transaction rules and transactions in the blockchain.The consensus mechanism also directly affects the distributed accounting methods of the public chain,such as leader election mechanism and ledger confirmation.Now,the mainstream consensus mechanisms in the blockchain network include PoW,PoS,DPoS,PBFT,etc.Each mechanism has its specific advantages and disadvantages and scope of application.The development team of the public chain needs to select an appropriate consensus mechanism according to its needs and characteristics.
Technical points
Building a public chain is a complex task that requires consideration of multiple technical points,which are inevitable components of public chain construction.The following are some important points:
1.Security:The security of the public chain is the most important factor.Developers need to consider how to handle potential attacks and failures,such as denial of service(DDoS)attacks,51%attacks,and double flower transactions.
2.Scalability:The public chain needs to gradually expand as the transaction volume increases.Therefore,developers need to consider how to increase network throughput and capacity without sacrificing on chain transaction speed.
3.Usability:In the development process of the public chain,a very important issue is how to enhance the usability of the public chain.This means that developers need to consider issues such as transactions,network latency,and device damage in offline environments to ensure the stability and continuity of the public chai
