㈠ Blockchain system development costs

The development cost of a blockchain project is generally estimated based on the technical difficulty.
Basically, the development cost of a blockchain is approximately Between hundreds of thousands and millions. Development costs are primarily calculated based on the number of developers and the hours of work invested. If there is ready-made source code that can meet the functional requirements, then development can be quickly achieved by modifying and adding functions, so the price is very low.
In fact, all the costs are in website development, manual maintenance, and hardware consumption. The cost of website development is basically determined by the investor's functions. Generally, the more functions a website has, the greater the investment.

㈡ Is the blockchain system development fee high?

The specific fee still depends on your specific needs, what you want to make it like, how many users you have in the early stage, how many users do you have in the early stage? Which model you plan to use, etc., are all part of the cost assessment. Of course, you can list your needs in detail, and then look for a development company to help you do it. The most important thing is to find a professional development company to help you do it, rather than just buying a system template.

㈢Blockchain technology development costs

Blockchain and Bitcoin are two sides of the same coin,

There is no way Separate,

But whether it is the financial circle or the technology circle,

while collectively singing the praises of blockchain,

but far away from the "Bitcoin" Black Singularity”.

Blockchain (blockchain) traceability

In the Satoshi Nakamoto white paper, there is no word blockchain (Blockchain) at all, only chain. The chain is just a subset of the Bitcoin system. Later, various copycat systems appeared. In order to abstract all systems into one concept, Mr. Zheng He conventionally coined a new word - Blockchain.

1. Blockchain is the original core technology of Bitcoin. Before Bitcoin was invented, blockchain did not exist in the world.

2. After the invention of Bitcoin, many people refer to the blockchain in Bitcoin and use similar technologies to implement various applications. This type of technology is collectively called blockchain technology and is implemented using blockchain technology. The various chains are called blockchains.

The relationship between blockchain and Bitcoin

The emergence and development of blockchain technology cannot be separated from Bitcoin. As long as When it comes to blockchain, Bitcoin is a topic that cannot be avoided. Because Bitcoin uses blockchain technology as its underlying technology, it was born based on blockchain, and the development of Bitcoin also stems from the momentum of blockchain; and the blockchain technology derived from Bitcoin can be The world is widely known and thanks to Bitcoin.

What is the relationship between the two? The following will clarify the connection and difference between blockchain and Bitcoin from three points:

1. The blockchain was born for Bitcoin

Satoshi Nakamoto originally wanted to create a system "based on cryptographic principles rather than on credit, so that any two parties who reach an agreement can make payments directly. An electronic payment system that does not require the participation of third-party intermediaries. In essence, Bitcoin is a new payment method. The core of its innovation is to rely on cryptography to remove the dependence of payment transactions on central institutions. That is, there is no longer a need for central institutions to take on account opening, transaction review, account balance change recording, etc. , realizing point-to-point direct transactions between users. If you are not a neutral technical person and just explain it from a libertarian perspective, you will get this analysis: Satoshi Nakamoto wanted to use encryption technology to transfer funds without relying on the central bank.

㈣ Blockchain technology development costs

Blockchain technology development costs are as follows:

The cost of blockchain technology development can be found from practice. There are significant differences, mainly influenced by development needs and complexity. According to the market level, the cost of a complete blockchain technology development project is at least 100,000 US dollars, and can reach millions of US dollars at most. The specific price depends on the complexity of the demand, the level of the development team, and the richness of blockchain knowledge. determined by other factors.

These servers are called nodes in the blockchain system, and they provide storage space and computing power support for the entire Yanyan blockchain system. If you want to modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes, and these nodes are usually in the hands of different subjects. Therefore, tampering with the information in the blockchain is a problem. This is an extremely difficult thing to do.

Compared with traditional networks, blockchain has two core characteristics: first, data is difficult to tamper with, and second, it is decentralized. Based on these two characteristics, the information recorded in the blockchain is more authentic and reliable, and can help solve the problem of people's mutual distrust.

㈤ What useful things can be produced by Bitcoin mining machines that waste so much electricity?

No matter what form or state it exists in, money is something that everyone likes. That's been the case from the beginning. When people established the concept of private property, they created general equivalents as evidence of exchange between the two parties. This equivalent has evolved from shells at the beginning, to copper coins, silver, gold, banknotes, etc., and there is even a Yap Island located in the Carlo Islands in the Western Pacific that uses stones for trading.

So I advise those who don’t know how to enter the market carefully. Bitcoin is not a store of value. Prices fluctuate greatly, and people who speculate in Bitcoin may become rich overnight, or they may become paupers overnight. And many countries do not recognize the legal utility of Bitcoin, and some countries even explicitly prohibit the use of Bitcoin. The above is just my personal opinion. Criticisms and corrections are welcome. If you agree with my opinion, please give it a thumbs up and leave, thank you! If you like me, please follow me, thank you again!

㈥ One article to take stock of the six core tracks of the Metaverse

An inventory of the six core tracks of the Metaverse

01, gaming/social media

With the continuous development and maturity of technologies such as the Internet, blockchain, and metaverse, the content industry under the new organizational form of the Internet will inevitably experience new breakthroughs:

1. Content density and interaction to a higher level

2. Greater user freedom and authority

3. Decentralization of distribution

Two major development directions in the game field : UGC games and blockchain games have received fundamental support for their development and are expected to become the vanguard of the metaverse wave. More importantly, games exist in a virtual electronic form and have a very strong mutual attraction with the concept of the metaverse. The Metaverse brings the reality of real life into games. Equipment and assets in virtual games can be linked to reality, and players can even build a complete industrial chain through games.

At present, the more representative metaverse games include Axielnfinity Decentraland and Roblox. Their characteristics include decentralization, monetization, open source, etc.

02. E-commerce

Technologies such as VR, AR and digital simulation will reconstruct the online e-commerce scene, and Metaverse has broad application prospects in retail. In the metaverse, you can create a shopping mall and complete your consumption in a game-like experience through the simple operation of placing an order with one click. In addition, Metaverse can also get rid of the form and function of physical stores, and more imaginative digital shopping experiences are being developed. The experience provided by Shenman Technology for retail e-commerce scenarios is changing the consumption patterns of users in the e-commerce field.

Gucci cooperates with Roblox to launch The Gucci Garden Experience virtual exhibition. Players can enjoy the exhibition and purchase virtual items. Tmall has launched a 3D version of Tmall Home Decoration Mall to provide consumers with a 360° presentation of furniture decoration effects, helping users browse different styles of decoration designs and make decisions. As the pandemic prevents consumers from frequenting beauty counters, L'Oreal is currently promoting Modiface AR technology to help customers try on cosmetics, such as lipstick shades and hair colors, through their phone cameras.

03. Office

Meta CEO Mark Zuckerberg said when talking about the Metaverse that the Metaverse widely helps people experience a sense of existence. Sense makes the way we interact more natural. Many of the meetings we have today are looking at a grid of faces on a screen. But we're used to being in the same room with people and having a sense of space, and if you're sitting to my right, that means I'm sitting to your left. In the future, you'll be able to sit on my couch like a hologram instead of just doing it over the phone.

Remote working has become more common under the influence of the new crown epidemic, but traditional remote working still faces some problems.For example, there is a lack of real-time interaction and low communication efficiency. The Metaverse can enable virtual office to be conducted in a face-to-face interaction manner. Google has launched Project Starline, which aims to create a 3D remote interaction format where participants can observe the chat partner from different angles and make physical or eye contact.

Facebook launched Horizon Workrooms, a remote collaboration tool that allows colleagues wearing VR devices to communicate face-to-face in the same virtual conference room, breaking the barrier of the screen.

04. Digital Collections

The domestic digital collections market is a branch of the metaverse that emerged after the overseas NFT concept. Due to strict regulatory policies and unclear policies, the industry formed is not yet complete. Among the many domestic digital collection market participants, technical service providers provide basic blockchain technology and related services as the infrastructure layer for digital collections. Numerous digital collection casting platforms provide digital collection providers with a package solution for casting, issuance, and sales of digital collections, and have become the primary trading market for the domestic digital collection industry.

In addition, although the distribution of domestic digital collections is mostly based on the PGC or UPGC model, in terms of quantity alone, 90% of the copyright-owning suppliers are individuals, which means that the top suppliers are mostly enterprises or organizations. , the digital collections issued by it are in short supply, and there is a price but no market. Followed by excellent individual suppliers and the second-tier corporate suppliers, and finally a large number of ordinary individual suppliers, forming a three-level and well-defined pyramid structure.

05. Virtual people

Virtual identity is the most basic dimension of the Metaverse. It has diversified application scenarios and commercialization paths. High fidelity, intelligence, and tooling are the characteristics of virtual people. Three major development trends. At present, the development of Nianduan virtual humans is in the stage of diversified development. The technology continues to mature and develop in various directions. Hyper-realistic virtual humans exist beyond the 2D form and can achieve independent emotional expression and communication. Virtual humans sprouted from early hand-drawn and 2D animations, and the concept of virtual humans was introduced from the film, television and music industry.

When virtual humans enter a stage of rapid development, deep learning algorithms, AI and other technologies have promoted the development of motion capture, expression capture, rendering and other technologies. Virtual humans can highly restore the image of real people and achieve real-time driving. Emerging technologies in various fields have promoted the accelerated growth of the virtual human industry. In recent years, virtual humans have placed more emphasis on the combination of AI and virtual humans, aiming to be applied in daily life and pan-entertainment scenarios.

06. Industry

Nvidia CEO Jensen Huang said in an interview that companies can rely on Yuanverse to reduce cost waste and improve operational efficiency. We're wasting a lot of stuff to compensate for the fact that we're not simulating, we're simulating factories in the metaverse, simulating plants, simulating real-world power grids and saving billions of dollars.

The industrial metaverse is a virtual space that is parallel to and independent of the real industrial world.The true mapping of the real industrial world in the digital world is the holographic digital industrial world.

Moreover, with the continuous development of cloud computing, 3D design, virtual reality (VR), augmented reality (AR), digital life, artificial intelligence, Internet of Things, blockchain, 5G, 6G and other technologies, With development and improvement, the industrial Yuanyu will become more mature, and the virtual industrial world will become closer and closer to or even surpass the real industrial world. When any aspect of industrial design, production, and manufacturing is empowered and supported by a widely used and mapped virtual world, this marks that the manufacturing industry has officially entered the era of the industrial metaverse.

㈦ How much does it cost to develop a blockchain?

"The development cost of a blockchain application app is estimated based on the functional complexity of the app. According to the startup technology forecast It is estimated that the development cost is between hundreds of thousands to hundreds of thousands. Generally speaking, the development time of apps with complex functions will be longer, and the cost will be higher. Apps with simple functions will be faster than Bohuzheng, and the cost will be higher. That is low. Development costs mainly include labor costs and hardware consumption. The more complex the function, the longer the app takes, and the corresponding cost will be higher. For example, if there is ready-made source code that can meet the functional requirements, then It can be developed quickly by modifying and adding functions, so that the price is very low."

㈧ How much energy is wasted by Bitcoin?

Although many countries do not recognize Bitcoin Value and status, but Bitcoin is still relatively popular in recent years, and its existence is highly controversial. Some people say that it has no practical significance and is just a number. If it is not officially recognized by the world, mining is a constant waste of energy. Some people also say, "One day in the currency world, one year in the world, no one can be sure whether Bitcoin is a dark horse or not."

In fact, Bitcoin is calculated through computer networking, also called mining. At first, there were personal computers that could mine, but the efficiency was relatively low, and Graphics card fee. Later, there were specialized Bitcoin mining machines, ranging from a few hundred to two to three hundred thousand yuan.

When we talk about Bitcoin, blockchain is naturally indispensable. Bitcoin becomes Bitcoin because of the blockchain, a secure ledger of all payments and transactions that everyone can contribute to updates. We need to solve a very complex mathematical problem - the hash algorithm through brute force cracking to complete a block.

Many people want to know how much a Bitcoin is worth. In fact, the price of Bitcoin changes all the time. We need to check the numbers of the day. The current price of a Bitcoin is less than 30,000.

㈨ Blockchain technology development costs

Because the development of blockchain software requires certain technologies, the cost is basically not low.
For example, blockchain wallets, blockchain exchanges, and blockchainChain browsers, blockchain malls, etc. cost hundreds of thousands. If it is to develop a single function, it will cost tens of thousands. If it is custom-developed blockchain software, the price will be higher.
In addition, the development cost of blockchain is also related to the following situations: Blockchain game development cost.
1． There are many types of blockchains: public chains, private chains, and industry blockchains. Prices will vary for different types of development.
2. Blockchain development functions: The more functions required, the higher the complexity and the higher the price, and vice versa.
3. Blockchain application port: Different development ports require different development costs. Cost analysis of blockchain platform development costs.

Since the development of blockchain software requires certain technologies, the cost is basically not low. Things like blockchain wallets, blockchain exchanges, blockchain browsers, and blockchain malls cost hundreds of thousands. If you want to develop a single function, it will cost tens of thousands. If you want to customize Yanhail to develop blockchain software, the price will be even higher.
