Decentralized community website

1. Whaleex: it's a decentralized exchange based on EOS. I usually choose it when I trade. The trading depth is good, and the transaction can be completed soon after I register. The best place is the high security. The smart contract passes the security audit and can be used safely
x protocol: a point-to-point open protocol running on Ethereum. The protocol aims to become a general open standard, as a basic mole that can be combined with other protocols to drive more and more complex blockchain applications. However, Ethereum is famous for its congestion, so its current situation is not very good
loopring
Road printing protocol: decentralized transaction protocol of class X. The on chain smart contract is responsible for asset custody, matching and transaction, and the off chain smart contract is responsible for order matching. It has an on chain trading loop matching technology, which encourages the exchange to match the transaction path with the maximum discount, so as to save transaction costs for users and make the exchange profitable at the same time. But on the other hand, it also increases the complexity of smart contract and the execution cost of Ethereum transaction, and the effect in practical application remains to be seen
there are also kyber, idex, bitstocks, etc. decentralized exchanges are the trend in the future, so there are still quite a few in the market. But comparatively speaking, I still think whaleex is the most reliable.

2. Compared with centralized trading platform, what are the advantages and disadvantages of decentralized trading platform
since 2013, many decentralized trading platforms have emerged. Different from the centralized trading platform, the decentralized trading platform does not need to register an account, and can participate in the transaction by using the personal digital asset account
secondly, every transaction of the decentralized trading platform is carried out through the blockchain, and it needs to wait for the confirmation of the blockchain before the transaction is successful. At the same time, the decentralized trading platform is not responsible for keeping users' assets and private key information. On the one hand, it avoids the moral hazard of the trading platform, on the other hand, it requires you to keep your private key well
e to the low liquidity and slow transaction processing of decentralized trading platforms, the total transaction volume only accounts for 0.03% of the global total transaction volume of digital assets. At present, the tokens of airswap, kyber, 0x and omisego can be traded on huobi.pro.

3. Network platforms, such as websites, need to use domain names. If they don't have domain names, they can't access websites. Now there are many kinds of domain name suffixes, such as. Top,. CN,. Com, etc. domain names can be used normally as long as they are renewed before the redemption period.

4. For example, this gotc is very good to use. You can try it. Moreover, they have been established for a long time and are relatively mature

5. I have been playing currency for many years, and I have used many trading platforms. I think the best one to use is gotc decentralized trading platform. First of all, this platform is a truly decentralized trading platform. On this platform, the power to initiate and agree transactions, as well as the power to quote, are in the hands of users, and the platform has no right to interfere or participate in the reconciliation. It's very safe and reliable.

6. Take gotc for example. All records can be queried through blocks, which is true and reliable
the order is linked in seconds, and the transaction is completed in an average of five minutes; Only 0.2% will be charged to platform merchants.

Blockchain technology can help us improve the security of encryption, authentication and other protection mechanisms, which is absolutely good news for the Internet of things security and DDoS Defense Community

blockchain has the potential to become an important solution for safe communities, as well as for the financial, energy and manufacturing instries. At present, verifying bitcoin transaction is one of its main uses, but this technology can also be extended to smart grid system, content delivery network and other application scenarios

how to apply blockchain to network security

whether it's protecting data integrity or using digital identification technology to prevent Internet of things devices from DDoS attacks, blockchain technology can play a key role, at least now it has shown this ability

Internet of things security and DDoS Defense Community

a blockchain startup claims that its decentralized "billing" system can help users resist DDoS attacks with traffic over 100gbps. Interestingly, the company said that this decentralized system allows users to rent their own extra bandwidth and submit their bandwidth access rights to the distributed nodes of the blockchain. When a website suffers from DDoS attacks, the website can use the leased bandwidth to mitigate DDoS attacks

improve confidentiality and data integrity

although the original design of blockchain did not consider the specific access control, now some blockchain technology implementation has solved the problems of data confidentiality and access control. In this era, any data may be tampered, which is obviously a serious problem, but the complete data encryption maliciously guarantees that the data will not be accessed or tampered by others through man in the middle attack in the transmission process

the whole IOT instry needs data integrity protection. For example, IBM's Watson IOT platform allows users to manage IOT data in a private blockchain network, which has been integrated into their big blue cloud service. In addition, Ericsson's blockchain data integrity service provides comprehensive audit, compatible and reliable data services to allow developers to use predix PAAS platform for technical implementation

one of the best applications is the transformation of our public sector and the creation of citizen centered infrastructure. This will enable the public to have their own identity and every transaction can be verified. We can use smart contracts and signed assertions to formulate elements of public services, such as benefits, etc

Internet of things & amp; Smart devices

now the attention of the whole IT community has begun to shift to the Internet of things & amp; Smart devices are on the rise, and security is absolutely one of the primary considerations. Although the Internet of things can improve our work and proction efficiency, it also means that we need to face more security risks. As a result, many companies seek to apply blockchain to protect IOT and instrial IOT (iiot) devices because blockchain technology can enhance authentication, improve data traceability and mobility, and assist record management

according to Alexey malanov, an anti-virus expert at Kaspersky laboratory, blockchain technology helps to track hacker attacks, adding:

"network intruders usually clear the permission log to hide traces of unauthorized access to devices. But if the logs are distributed in multiple devices (for example, through blockchain Technology), the risk can be reced as much as possible. "

German Klimenko, chairman of the digital economy development fund, said: "at present, the Ministry of defense is vigorously promoting it development and research, which is a good thing for the instry."

NATO and the Pentagon are also studying the "defensive" Application of blockchain. This technology is actively used to protect the system from network attacks. NATO will use blockchains to protect financial information, supply and logistics chains, while the Pentagon is developing a data transmission system to prevent hackers

in general, blockchain technology is not omnipotent, at least not yet. Whether from the perspective of technical integrity or system implementation, the current blockchain technology can not guarantee the security of the device 100%. Note: the above content comes from the Internet

8. If it is truly decentralized, there will be only one dotc.pro, and the others are not truly decentralized. Dotc.pro, from transaction to transfer currency, is settled on the smart contract chain, not on other platforms

9. Specifically, in short, the service provided by the OTC area is similar to the digital currency Taobao. Users can freely display their digital currency assets on the platform, and conct point-to-point legal currency trading with people from all over the world. The platform does not participate in trading and mixing, and the whole process is supported by EOS blockchain technology. Gotc is OK

10. These websites themselves are very unstable,
if you can't open them, wait a while,
maybe you can open them later.
