⑶ How can enterprises build their own blockchain

Hello, thank you!

How can enterprises build their own blockchain?

With the popularity of various currency transactions, the development of the exchange industry has been driven. So as a novice who wants to cross industries, how to establish a blockchain exchange development company? Chainsoft Network summarizes the following points for you.

Please click to enter the picture description

1. Determine the operating scope of the exchange development company

Determine the company's The scope of operations is very important, as it determines whether the company has the potential to be profitable. Relevant laws and regulations vary from region to region every day, so the first step is to understand the local laws and regulations, and obtain the necessary licenses and approvals to open a Bitcoin exchange according to your scope of operations, to avoid violating local laws and regulations, and bring To cause unnecessary trouble.

2. Check the country’s regulations and compliance requirements

Almost all governments require entities involved in currency exchange businesses to comply with Know Your Customer (KYC) norms. KYC is the process by which businesses verify the identity of their customers through a government-issued ID card or passport. The main purpose here is to prevent money laundering. Make sure to comply with your country’s KYC norms and integrate the right client into your exchangeAccount verification process.

3. Work with a bank or payment processor

You need to work with a bank or payment provider to process payments via fiat currency. You can choose a trustworthy bank with extensive online facilities.

4. Create liquidity on your exchange

Any exchange needs liquidity to operate successfully. Customers are hesitant to place an order or even deposit funds unless they see complete order and trading activity. New trading naturally encounters liquidity issues.

5. Ensure high-level security of trading and customer data

Any exchange development company needs top-notch security to ensure exchange operators and traders’ funds are maintained Safety. This should also apply to your customers’ private data, including their KYC details and bank account information. The Gox breach, a security flaw that went unnoticed for years, resulted in the theft of nearly 1% of all Bitcoins in circulation at the time. According to Chainsoft Network, one-third of all Bitcoin exchanges were hacked between 2009 and 2019. Therefore security must be your top priority in trading.

6. Establish customer support channels

Finally, customer support is another important component of a successful exchange. Staff are needed to approve KYC requests, answer customer complaints, process deposits and withdraw fiat currency, etc. A fast customer support mechanism ensures that your customers start trading from the day they sign up and generate revenue for your exchange.

I hope this helps you solve related problems. For more details, please feel free to consult and discuss!

⑷ How to build a blockchain platform

In many cases of blockchain commercial applications, we can always see the word BaaS, which means Blockchain as The abbreviation of a Service, translated into Chinese as "Blockchain as a Service". So what exactly is Blockchain as a Service BaaS? With this question in mind, we followed Xiao Wang from the Renren Blockchain Technology Team to discuss it in detail.
According to Xiao Wang: Blockchain as a Service BaaS is a concept mainly proposed by the two giants Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service that combines blockchain technology. . For example, Microsoft's Azure cloud computing platform and IBM's Bluemix Garage cloud platform both provide blockchain as a service BaaS.
Blockchain as a Service (BaaS) is a space created by companies such as Microsoft and IBM from their own cloud service networks to run a certain blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of BaaS nodes is to quickly establish the development environment you need and provide a series of operational services such as blockchain-based search queries, transaction submissions, and data analysis. These services can both It is centralized or decentralized, and is used to help developers verify their concepts and models faster. BaaS FestivalThe serviceability of Dot is reflected in: stronger tools, making it easier to create, deploy, run and monitor blockchains.

⑸ What are the technological innovations and applications of blockchain?

1. Blockchain system

As the underlying technology of Bitcoin, the blockchain system It is generally composed of data layer, network layer, consensus layer, incentive layer, contract layer and application layer.

1. Data layer

The data layer encapsulates basic data and basic algorithms such as underlying data blocks and related data encryption and timestamps. It mainly describes the physics of the blockchain. The form is the chain structure on the blockchain starting from the genesis block. It includes the block data and chain structure of the blockchain, as well as the random numbers, timestamps, public and private key data on the blocks, etc. It is the underlying data structure in the entire blockchain technology.

2. Network layer

The network layer mainly implements distributed network mechanisms through P2P technology, including P2P networking mechanisms, data dissemination mechanisms and data verification mechanisms. Therefore, in essence, the blockchain is a P2P network with an automatic networking mechanism, and nodes maintain communication by maintaining a common blockchain structure.

3. Consensus layer

The consensus layer includes consensus algorithms and consensus mechanisms. The consensus layer allows highly dispersed nodes to efficiently reach consensus on the validity of block data in a decentralized blockchain network. It is one of the core technologies of the blockchain and the governance mechanism of the blockchain community. There are currently dozens of consensus mechanism algorithms, including proof of work, proof of equity, proof of equity authorization, proof of burning, proof of importance, etc.

4. Incentive layer

The incentive layer mainly includes the issuance system and distribution system of economic incentives. Its function is to provide certain incentives to encourage nodes to participate in the security of the blockchain. Verification work, and incorporating economic factors into the blockchain technology system, incentivizing nodes that abide by the rules to participate in accounting, and punishing nodes that do not abide by the rules.

5. Contract layer

The contract layer mainly includes scripts, codes, algorithm mechanisms and smart contracts, and is the basis for blockchain programmability. It embeds code into the blockchain or token, and can implement customized smart contracts. When certain constraints are reached, it can be automatically executed without going through a third party, which is the basis for trustless blockchains.

6. Application layer

The application layer encapsulates various application scenarios and cases, similar to applications on computer operating systems, portals on Internet browsers, search Engine, e-mall or APP on mobile phone. It deploys blockchain technology applications on Ethereum, EOS, QTUM, etc., and implements them in real life scenarios. In the future, programmable finance and programmableCheng Social will be built on the application layer.

The data layer, network layer and consensus layer are necessary elements to build blockchain technology. Without any layer, it cannot be called blockchain technology in the true sense; the incentive layer, contract layer and The application layer is not a necessary factor for every blockchain application, and some blockchain applications do not completely include this three-layer structure.

From a business perspective, blockchain technology has its own characteristics, that is, it is sufficiently digital, it is cross-border, cross-time and space, and cross-organization. The flow of data has no boundaries, so the blockchain is distributed at the same time, it is self-organized and decentralized.

So the origin of blockchain and the application of any new disruptive technology have always had two routes, or two methods. One way is to regard it as a tool and use it to improve the traditional business model and obtain an improvement in marginal benefits. The other is to treat it as a system to reconstruct the underlying logic of business.

There is a good example of these two application methods in the past few years. When Internet companies are promoting "Internet+", we also see many traditional business organizations saying that it is not "Internet+", but "+Internet". So where are those people who shout "+Internet" now? Some people think that the Internet is just a technology used to improve traditional things, and some Internet technologies can be added to traditional things. For example, if you use the Internet as email, you build an email system and think it is the Internet. But some people treat the Internet as a system and reconstruct the business from the bottom up. In the end, you will find that you are unemployed.

The second is decentralization. Why go to the center? Regional center technology in business has brought about business decentralization, which is an inevitable trend in history. Where is this trend? I think there are two points. One is economic globalization and entering version 2.0. Now through the Internet, it is no longer the company that is globalizing, nor the company turning itself into a multinational company, but the Internet is empowering any individual, so that it can sell its products through the Internet in a small county in China. worldwide. When economic globalization develops to personal globalization, solving point-to-point transactions and point-to-point services becomes a prominent issue. Then the real-time clearing and settlement and point-to-point transaction settlement brought by blockchain technology can just help the globalization of personal business activities.

The third is the digitalization of the economy. When data is collected to a certain extent, its circulation is basically across time and space. The demand for financial payments from commercial activities is carried with them anytime and anywhere, but it is impossible to provide scenario-based and virtualized payment settlement anytime, anywhere and on demand. Services will eventually be eliminated by technology and the market.

⑹ As an entrepreneur, how should we focus on blockchain technology?Use technology to build your own business model

This requires you to conduct market research to see what pain points blockchain can solve in reality.
For example, the problem of opaque public voting can be solved using blockchain, and some people are already doing it abroad.
Using blockchain technology for crowdfunding, domestic European crowdfunding is currently doing this, combining digital currencies with physical assets.
Data storage, using blockchain technology to store data, prevent data theft, etc.

⑺ How to build blockchain services

Blockchain services refer to developing public chain applications based on the infrastructure provided by the public chain and running the applications to provide services. For example, smart contracts are used to develop public chain applications on Ethereum and run on Ethereum nodes to provide effective services to the public. On Bitcoin, some certificate deposit services are provided using the limited functions of Bitcoin.
Blockchain developers should establish effective channels that can collect the shortcomings of the current blockchain and make targeted improvements. This process is called Improvement Proposals: Bitcoin Segregated Witness ( Consisting of a series of BIPs) is a good example. Developers at the application layer can use the IP process to feed back problems discovered during use to developers, forming a virtuous cycle. And the IP process should not be limited to the technical field, but should go deep into the Business Layer.
