360 Korea blockchain

1. I've learned about this TTC project and participated in the activities. The main network of this project just launched this year is also making wallets. It's building their own TTC ecology, payment, social networking, advertising and so on. It's a big game of chess

I understand that their ecological goal is

master-slave chain structure
the main chain is used for asset trading, with high security requirements; The slave chain is used for data transaction with fast speed

payment solution
the solution for TTC asset transfer. By accessing the TTC payment SDK, anyone can take TTC as a new payment method

win-win ecosystem
TTC is committed to building a stable ecosystem for super nodes, voting users, DAPP developers, users, users, etc Businesses provide value

TTC connect
TTC connect builds a bridge between users and TTC, users can transfer assets, reward synchronization, vote for super nodes, pay with TTC, etc.

TTC is a blockchain solution for large transaction volume and a sustainable token economy model. In foreign well-known market website coinmarketcap and domestic well-known market website non small can query<

TTC is developing rapidly. In March this year, TTC released version 2 of TTC white paper, launched TTC main network and launched TTC connect. In addition, TTC has already been online in major exchanges, such as upbit, the largest exchange in South Korea, coinzest, tokocrypto, bitrex, bibox and bitforex

consensus mechanism is the core of blockchain. After decades of development, consensus mechanism has derived a variety of consensus algorithms from the initial single workload proof pow, such as asset proof mechanism POS, proxy asset proof mechanism dpos, Byzantine fault-tolerant algorithm BFT and so on. Each consensus algorithm has its own advantages and disadvantages. TTC platform is designed to deal with large-scale transactions and support rapid verification. It uses multi-layer bft-dpos as the consensus mechanism

multilayer BFT dpos is a consensus algorithm based on dpos, and a series of super nodes generate blocks on behalf of all users, which improves the speed of transaction confirmation through BFT mechanism

this is the most I know, many of them are seen on the website, I hope it can help you;

Recently, Vulcan team of 360 company found a series of high-risk security vulnerabilities in EOS, a blockchain platform. It is verified that some of the vulnerabilities can remotely execute arbitrary code on EOS nodes, that is, they can directly control and take over all nodes running on EOS through remote attacks

In the early morning of May 29, 360 reported this kind of vulnerability to EOS official for the first time, and assisted it to repair the security risks. The person in charge of the EOS network said that the EOS network will not be officially launched until these problems are fixed

EOS super node attack: the virtual currency transaction is completely controlled

in the attack, the attacker will construct and publish a smart contract containing malicious code, and the EOS super node will execute the malicious contract and trigger the security vulnerability. The attacker then uses the super node to pack the malicious contract into a new block, resulting in the remote control of all nodes in the network (alternative super node, exchange recharge withdrawal node, digital currency wallet server node, etc.)

because the system of the node has been completely controlled, the attacker can "do whatever he wants", such as stealing the key of the EOS super node and controlling the virtual currency transaction of the EOS network; Obtain other financial and privacy data in the participating node system of EOS network, such as digital currency in the exchange, user key stored in the wallet, key user information and privacy data, etc

What's more, an attacker can turn a node in the EOS network into a member of a botnet, launch a network attack, or become a free "miner" to extract other digital currency

3. It takes 57 days for rx470 and 100 days for 1070. I hope you can get rid of this idea. Now the appreciation of the virtual coin country is choking, so we need to be cautious< br />

4. Under the AA blockchain ecology, a community of benefits has been formed, and a brand-new live video blockchain ecological scene has been built for the business of "Multi Chain, aggregation and chemical reaction"
Company background
South Korea Kaa, a cultural and entertainment property company with the most advanced star making system in Asia, has created 60% of the mass media announcers and hosts in South Korea. With the first-class cultural civilization system and mature artist operation form, we have a complete grasp of the property proction process from excellent ordinary people to budding artists. Kaa platform, therefore, is the first community-based new media ecosystem focusing on the live broadcast platform of reward and mining, covering the key upstream and downstream aspects such as labor, cost and service. Through the blockchain technology, the anchor, fans, community and users are closely linked to form a community of benefits, build a mutual win-win blockchain ecological scene, and realize the capital integration and the maximization of the benefits of all parties
name introction
under the blockchain ecology, the world's first reward mining live broadcasting platform provides common sense ecation throughout the system for the blockchain instry, identifies the good and bad names, and creates a new platform for cost sharing and cost acquisition. Kaa platform integrates artist course training, artist packaging, online live broadcasting, token spending, reward mining and business. It combines the current hot spots of live broadcasting and blockchain reward mining to create a new blockchain token ecology

5. It seems that there is such a thing.
to be exact, it is some high-level South Korean government officials who gave AOS platform. At the end of 2019, AOS held a road show in South Korea. The South Korean army chief of staff and a number of members of Congress attended the meeting, and the community also took photos
the shareholders behind the AOS project are certainly not ordinary people. Just like the shareholders behind OK trading and Huo coin exchange, they all have backgrounds. Many of AOS's playing methods are not small workshops or air currency routines. AOS is completely following the orthodox route and is engaged in blockchain technology and application.

It was reported on May 29 that recently, Vulcan team of 360 company found a series of high-risk security vulnerabilities in EOS, a blockchain platform. It is verified that some of the vulnerabilities can remotely execute arbitrary code on EOS nodes, that is, they can directly control and take over all nodes running on EOS through remote attacks

the hidden dangers of blockchain network security need to be paid attention to

EOS is a new blockchain platform known as "blockchain 3.0". At present, its token market value is as high as 69 billion yuan, ranking fifth in the global market value

in the blockchain network and digital currency system, nodes, wallets, mines, exchanges and smart contracts all have many attack surfaces. 360 security team has found and exposed several serious security vulnerabilities for digital currency nodes, wallets, mines and smart contracts

this time, the 360 security team found a series of new security vulnerabilities in the smart contract virtual machine of EOS platform, which is a series of unprecedented security risks. No security researchers have found such problems before. This type of security problem not only affects EOS, but also may affect other types of blockchain platforms and virtual currency applications

360 expressed the hope that through the discovery and disclosure of this vulnerability, the blockchain instry and security peers will pay more attention to the security of such issues, and jointly enhance the security of the blockchain network

According to foreign media reports, South Korean Internet giant kakao will officially launch the encrypted wallet "klip" in the second half of this year. On August 12, kakao talk announced the notice page of "klip", through which users can store and manage the karay token. According to the analysis, "klip" will also support cryptocurrency issued by the blockchain platform klaytn. As early as last March, kakao announced the plan to launch the blockchain platform, and released the test network of the blockchain proct klaytn in October last year

it is said that after launching the blockchain platform klaytn main network, kakao will release klaytn's encrypted wallet and import it into its chat application kakaotalk

8. Save the page on the screenshot ah, but in fact, there is a rule that the next time you log in with your mobile phone number, you can see your cat, do not need to save the page alone.

9. 360 will be released in the evening. It is said that Netease is now running very well. The black diamond is relatively stable. The promotion mode is also steady. It is not extreme, but it is also in the forefront. With the graal maturity of technology, it will become better and better; It was the first and popular one. At that time, it was able to lead a lot of dogs, but now it is also very popular. Each blockchain represents its own company brand, and its development will not be poor. If China's network giants can't play blockchain well, other technical forces will be poor, too...

10. Blockchain 360 blockchain is a fast-moving technology, which fundamentally changes finance, supply chain, medicine, insurance, law and commerce. Join the host, Bryant Nielson, and he just
