The explosive blockchain gives people unlimited fantasy. When many people think about the benefits of blockchain, one of its problems has aroused people's concern, that is, security. Some time ago, 360 discovered a high-risk vulnerability in the blockchain, which can control all the nodes on the EOS. We all know that 51% of the nodes in the blockchain can tamper with the data, let alone 100%. Let's see what's going on
On May 29, 360 Vulcan team announced that it had discovered a series of high-risk security vulnerabilities of EOS 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. For more details, please clickNow the most popular is the blockchain. Now people continue to join the blockchain instry. Even some giant enterprises are also studying the blockchain. Some people say that the blockchain is a fraud, and others say that the blockchain is the hope of the future. Let's explain it
1. Is blockchain a Ponzi scheme
No, blockchain is a technology. Technology itself can't commit a crime without self-consciousness
blockchain is essentially a decentralized accounting system
What is decentralization? Take chestnuts for example:in Guaizi village, Cuihua has an affair with Lao Wang next door and is seen by Li Si. After that, Li Si told everyone in the village about it. As a result, Cuihua and Lao Wang Dao are well-known about the affair. For more details, please click
it is the birthplace of blockchain technology, and the market has confidence in it. It still maintains a stable growth under the adverse situation of major policies. Once it solves the problem of capacity expansion, the price rise can be predicted
2. Ethereum
compared with bitcoin, the advantage of Ethereum is that it has no policy problems. Although the event led to its bifurcation, the establishment of enterprise version Ethereum alliance may solve this problem. Its concept and Prospect of smart contract attract many developers to follow
the essence of community operation is that the majority decides the minority when indivials support eth
3. Zec
compared with bitcoin and Ethereum, the risk of z-coin will be greater, and its value will take a longer time to reflect. But in the long run, the value of anonymity will be one of the values that human beings generally pursue
4. BTS
bitstocks are very powerful and the system is very stable. Decentralized trading, anchoring system and so on. Although the founder bm's brain damage has hurt the community, the value of bitstocks is obviously undervalued. It is a wise choice to hold bitstocks on the cheap.
the MLM currency of blockchain will collapse on the day when the capital chain breaks as the underlying technology of bitcoin, "blockchain" is like a distributed database ledger. With the price of virtual currency based on blockchain technology such as "bitcoin" soaring, ordinary investors are increasingly interested in blockchain and digital currency
Li Xuyang, head of Tencent's security and anti fraud laboratory, said that there are more than 3000 MLM platforms using the blockchain concept. The reporter's inventory of recent cases found that "blockchain + fraud" mainly has three "routines"
extended data
with the sharp rise and fall of bitcoin and the explosion of the concept of "blockchain", many pyramid schemes under the banner of "blockchain" also appear frequently
putting on the "new vest" of blockchain, the "old routine" immediately incarnates another "new shortcut" of "Chinese aunts" in pursuit of "financial freedom" and "big pits" worth hundreds of millions. Experts suggest that relevant departments establish a joint supervision and joint strike mechanism, improve the ability of risk investigation, and timely cool down the excessive speculation chaos of "blockchain"
