1. It also depends on what kind of blockchain app you develop. A simple one can be done with thousands of yuan, and a complex one can be done with tens of thousands or even hundreds of thousands of yuan
2. Different companies have different prices. As for the blockchain system, Shengshi Huacai company has specialized research, with good service, good technology and high cost performance. You can consult Shengshi Huacai company in Shenzhen.
3. As we all know, there are many blockchain projects. The common ones are: mobile phone mining, digital currency development (token), digital currency exchange, digital currency wallet, blockchain mall, blockchain pet cultivation, blockchain games...
blockchain development needs to be determined according to the development methods and functions. Customized development is expensive, and it will be very expensive if there are many and complex functions, Therefore, this specific price can only be expressed in a specific scheme.
4. How much does it cost to develop a blockchain application? For example, blockchain digital wallet
there are many kinds of blockchain digital wallet apps. For example, online applications can be divided into many kinds, including full node wallet, light wallet and centralized wallet. In addition, they can be divided into single chain wallet and Multi Chain Wallet, while offline applications can be divided into paper wallet and hardware Wallet
the development costs of different types of blockchain digital wallets are very different. For example, the development costs of single chain wallets and Multi Chain wallets are different because of the different system types used in the development. It can be known that the development of Multi Chain wallets is more difficult, because the quotation will be much higher than that of single chain wallets.

Ethereum miner fee

1. In a public chain, anyone can read and write data. Reading data is free, but writing data to the public chain costs a certain amount of money, which helps to prevent junk content and protect its security through payment

Secondly, any node on the network (each connected device containing a of the account book is called a node) can participate in the mining method to protect the network. As mining requires computing power and electricity charges, miners need to be paid for their services, which is also the origin of miners' fees

Third, the difference between Ethereum and bitcoin, Ethereum introces the concept of gas, the purpose of which is to limit the amount of work required to execute the transaction and pay for the execution. Gas is used to measure the resources (including computation, storage, bandwidth, etc.) consumed by your transaction (or contract code call)

extended data:

ten rights of miners:

1. The "ten rights" of coal mining enterprise workers in safe proction include: the shift leader does not go down the well, and the workers have the right not to go down the well; The workers have the right to leave the well early if the shift leader leaves the well early; Workers have the right not to work if potential safety hazards are not investigated; If the management personnel command against rules and regulations, the workers have the right not to carry out them

Without safety measures, workers have the right not to start work; Workers have the right not to go down the well if they don't organize safety study before class; If the "Trinity" (monitor, safety inspector and gas inspector) safety inspection is not carried out, workers have the right not to start work

The workers have the right not to start the work if the detection and monitoring system is not installed in place and operates abnormally; Workers have the right not to go down the well if they are not equipped with fully qualified labor protection and protective equipment; The route to avoid disaster is not marked, and workers have the right not to go down the well. The coal mine shall not dect the wages and dismiss the workers for the above reasons

Eth trunk interface is a kind of interface that can be created dynamically. This type of interface can be bound with several physical Ethernet interfaces and used as a logical interface to increase bandwidth and improve reliability

The advantages of

trunk are as follows:

1. Load carrying through trunk interface and traffic load carrying in eth trunk interface

2. When a member's interface is connected to the physical link, the traffic is switched over, and the link is used to improve the reliability of the whole trunk link

3. Total bandwidth of trunk interface

extended data:

trunk specific application

1. Trunk function is used to connect the switch and the server, providing the server with exclusive high bandwidth

2. Trunk function is used for cascading between switches to provide high bandwidth data transmission capacity for data exchange between switches, improve network speed, break through network bottleneck, and then greatly improve network performance (main application)

trunk function example

-- for example, in order to increase the bandwidth and improve the connection reliability, an Internet bar movie server is a al network card, which is bound and connected with 23 and 24 ports of the central switch; If the 1 and 2 ports of the layer 2 switch are connected with the 1 and 2 ports of the central switch, then the central switch needs to make the 1, 2 ports, 23 and 24 ports trunk respectively. Note: the layer 2 switch here also needs to support trunk

7. The difference between gold futures and international spot gold
gold futures
International Spot gold
trading variety: gold (99.95%)
gold (99.99%)
trading unit: 300g / hand
1 hand = 100oz
quotation unit: yuan / g
USD / oz
minimum price change: 0.01 yuan / g
0.1 USD / oz
fluctuation limit: International Spot golden wave Dynamic four dollar gold futures fluctuate 1 yuan (spot gold is in line with international standards)
trading time: 9:00 a.m.
11:00 p.m.
1.30 p.m.
3:00 p.m.
20 hours a day (7.30-3.30)
Trading Margin: 7% of the contract value
1 hand / 1000 U.S.
transaction handling fee: 2 / 10000 of the completion price
1 hand / 100 U.S.
both have advantages and disadvantages
it depends on how you choose It's too late
the minimum margin for the listing of gold futures contracts is tentatively 9% of the contract value. From the date of listing to December 31, 2008, the handling charge for the trading of gold futures contracts is tentatively 30 yuan / hand
this is the gold variety of futures companies
the handling charge of spot gold is: 50 dollars per hand + 0.5 point difference

8. In the process of digital currency transfer, such as BTC and eth, miners' fees need to be paid. Miner's fee is the fee given to miners in the blockchain network, which can encourage miners to package transactions and maintain the safe and stable operation of the blockchain network. Miner fees can also be understood as transaction costs in blockchain network, similar to transfer fees in daily life
characteristics of miner's fees:

miner's fees are constantly changing, and the specific amount is determined by the status of the blockchain network at that time
different blockchain networks have different ways to calculate miners' fees
the higher the miner's fee is, the better the transaction will be packed by the miner
not all token transfers need to pay miner's fees, for example, EOS and Tron transfers do not need to pay extra miner's fees
the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.
9. Miner's fee refers to the incentive fee paid to miners ring digital currency transfer. This amount is not fixed. Of course, the more miner's fee you pay, the faster it will be packaged. It can be understood as the transaction cost in the blockchain network. If you are interested, you can learn about celletf
