Comparison between decentralized autonomous organization and com

1. Dao (data access object) data access object is an object-oriented database interface, which can also be called its decentralized self-made organization. It reveals the Microsoft Jet database engine (used by Microsoft Access), and allows visual basic developers to connect directly to access tables through ODBC as if they were directly connected to other databases. Dao is most suitable for single system application or small local distribution.

2. It can be regarded as a company that operates without any human intervention and gives all forms of control to a set of unbreakable business rules.

1. about the variability of blockchain

2. eth, if most people agree to modify the chain, that is, variability, then they can modify the blockchain records and contracts

3. etc, blockchain records and contracts can't be modified, that is, they can't be tampered with

4. here are the advantages and disadvantages of the two methods

   The advantage of

5. variability is that people can make timely changes to make the right decisions. Therefore, modifying the specification is more practical than finding loopholes

6. non modifiability means that no matter how smart people are at that time, it is impossible not to make mistakes. Therefore, when problems arise in this scheme, it is best to find and solve the loopholes through the existing legal framework

7. differences in development

8. eth, whether it is intentionally arranged or since its birth, the core decisions of blockchain are made by Ethereum foundation with the participation of the community and most of them are developed by it

9. etc, the decision-making of blockchain is mainly decided by the feedback of three loose, collaborative teams with community participation

10. in any case, anyone can put forward improvement suggestions for the two kinds of blockchains. This is the benefit of open source, and it is also very common. You will find that developers of the two chains communicate with each other through GitHub and reddit. I hope to improve the frequency of communication in order to achieve the common goal

11. about compatibility

12. at present, the two kinds of blockchains are compatible with each other. Contracts or applications written by eth can be applied on etc, and vice versa

13. eth, focusing on ewasm, is committed to providing a platform for more and more developers, while the issue of contract security is secondary, such as viper

14. etc focuses on making developers create more secure contracts, such as viper, iohk research, at the cost of consuming the number of potential developers

15. it's obvious that both chains can accept each other, regardless of whether their wishes are the same or not. My view is that the number of developers is not necessarily related to the quality of the proct

16. about the transaction speed

17. eth, the average is 25 seconds, which will be shortened after upgrading

18. etc, with an average time of 14 seconds, maintained at 10-14 seconds after upgrade, according to ecip-1010 and ecip-1036 protocols

19. about the block capacity

20. eth, with the daily trading volume of eth graally reaching 5 million, the block capacity is graally saturated. This situation is similar to the recent transaction cost of bitcoin. This problem can be solved by expanding the block capacity by increasing the default fuel limit

21. ETC­， At present, there is still a lot of room for block capacity. As more and more people accept etc, the block capacity will also increase, just like eth

22. about community

23. eth, mainly discuss on reddit

24. etc, mainly discuss on slack

25. about monetary policy

26. eth, the planned supply is growing steadily, resulting in an average inflation of 3% in eth blockchain in its life cycle

27. etc, before 2025, inflation will reach 3%, and then the total supply will reach 200 million etc, and then there will be deflation

    As for the regional distribution of trading volume, China accounts for 20%, South Korea 25% and the United States 25%
    In etc, China accounts for 50%, South Korea 25% and the United States 10%
    About securities, at present, investors do not have the option to trade securities. Recently, one of eth's ETFs, trading open-end index funds, was denied by the regulators

28. etc owns etc trading trust, which allows investors to own etc instead of the asset itself

1. Different network architectures:

decentralized application (DAPP) runs on the distributed network, the information of participants is protected (or anonymous), and the decentralized operation is carried out through different people in the network nodes. Distributed network is made up of node computers which are distributed in different places and have multiple terminals. When any line in the network fails, the communication can be completed through other links, which has high reliability

traditional app needs services provided by third-party service providers, and can achieve wireless network access through mobile communication network, which belongs to the centralized network architecture mode

2. Different from open source:

DAPP applications must be open source. Most of the tokens issued by DAPP run independently rather than controlled by an entity. All data and records must be encrypted and stored on a public and decentralized blockchain

traditional app software, games, navigation and other applications are generally provided by third-party service providers, which should solve the problems of right protection and economic interests, and their programs are not open source

extended data

in 2018, a large number of new DAPP projects were launched. According to the statistics, there are about two or three thousand dapps in the whole network. According to the DAPP survey of fluence labs, 72% of DAPP projects were launched in 2018. This means that in the past year, the number of dapps in the whole network has more than tripled

of all dapps, more than 80% are developed on Ethereum, about 20% on EOS and less than 10% on Tron. It is worth noting that about 10% of the projects are developed on multiple main chains at the same time, while the number of dapps developed on other main chains is relatively rare

there are about ten projects based on gxchain, mainly small applications in block city

5. HNB community set up a GMH, the policy and decision were voted by decentralized participants, executed by smart contract, without human intervention. Major issues shall be discussed and voted by the general meeting of all community members. The full-time boards (development board, reserve board and arbitration board) authorized by GMH perform their respective ties. It effectively protects the rights and interests of all.

6. Illegal fund-raising is not a real virtual currency. A very significant feature of deceiving "virtual currency" is the unilateral rise of investment income. The total amount of real virtual currency is limited, and the price fluctuates. However, the price of virtual currency under the illegal fund-raising scam tends to rise unilaterally, and the assets of investors' books have been increasing. Once the scam can not continue, These fake virtual currencies are worthless, and investors have nothing to lose. At present, in addition to bitcoin, there are eth Ethereum, usdt TEDA, inmi and other regular currencies.

7. They are all excellent digital currencies. We recommend the coin easy platform, support RMB direct recharge purchase, recharge withdrawal and instant account arrival!

8. Eth is the code of Ethereum, and Ethereum is the token on Ethereum blockchain. At present, many people are investing and trading in Ethereum. For novices, they may be a little confused about the operation mode of ether currency. In fact, the transaction of ether currency only needs to predict its price rise and fall trend on the domain Kingdom, and make a correct judgment to make profits. Although the minimum single transaction is $5 and the transaction cycle is as short as 30 seconds, be careful not to trade frequently or heavily.
