quartz for jewelry making wholesale Bitcoin exchanges are always attacked by hackers, what should I do?

jewelry wholesale atlanta At present, most digital currency transactions are conducted on the exchange. Among the many exchanges, more well -known are Bitfinex, Binance, OKEX, etc.
, digital currencies such as Bitcoin, as decentralized assets, must be traded in a centralized exchange, which seems to hide contradictions and dangers in itself.
1. Exchange problems and challenges
In February 2014, the world's largest Bitcoin exchange MT.GOX was stolen 850,000 Bitcoin, and Bitcoin prices suffered a "cliff -style" plunge on the same day. Later, MT.GOX was exposed to adure self -theft. There were only 7,000 Bitcoin that was truly stolen.
In August 2016, the largest US dollar Bitcoin trading platform BITFINEX appeared security vulnerabilities, causing 120,000 Bitcoin to be stolen at the time worth $ 65 million. If it was converted to the price of December 2017, it was worth nearly 2 billion US dollars.
On December 19, 2017, the South Korean Youbit Exchange was attacked by hackers and lost 4,000 Bitcoin. The exchange announced bankruptcy.
On December 21, 2017, 60,000 Bitcoin was stolen on the Internet of Ukraine LIQUI exchanges, and the unit price of Bitcoin fell US $ 2,000 instantly.
In 2018, such a drama will only continue.
In addition to the threat of hackers, traditional exchanges also have some shortcomings, such as lack of supervision and inefficiency. The security guarantee for the security of investors can only rely on their own credit, and the cost of running is very low. Stock transactions have a national supervision, but the digital currency exchanges do not have such a sword of Damocolis. Moreover, in the exchange, the same order can only be submitted to an exchange. After the user places the order, the capital used for transactions will be frozen, and only the transaction can be completed or canceled. These are undoubtedly inefficient.
The is easy to be attacked, lack of supervision, and inefficient. In short, the problems of the exchange are all centralized issues.
2. The decentralization of the exchange
(1) The progress of the exchange itself
has upgraded the upgrade of security methods. At present, the best is the cold wallet, which is to put it, that is, it is to put it, which means that it is the one, which is the cold wallet. Digital currency is stored in offline U disks. At the end of 2017, when the Youbit exchange was attacked, 75%of the assets were timely withdrawn into the cold wallet to avoid greater losses. However, it seems to be a helpless way to protect the assets of the network. Of course, there should be many other ways, so I won't go into details here.
(2) Cross -ledger transaction
The representative of this aspect is Ripple network. The operating company is Ripple Labs, which is a semi -center -level system. Ripple is a decentralized liquidation protocol. In order to solve the high cost and high delay of inter -bank liquidation, its basic currency is Ripple (XRP). The Ripple network can connect various assets, such as the US dollar, RMB, yen, Bitcoin, etc. to their own network. In this system, the US dollar or Bitcoin can be exchanged to Ripple, and then Ripple is freely circulating in the network, as if a highway of circulation has been built between various assets. Because of the support of major banking institutions, Rippo achieved nearly 300 times the growth in 2017.
(3) Decentralization exchanges
It some teams tried to use blockchain technology to build decentralized exchanges. This decentralized exchange is an extension of cross -ledent transactions to some extent.
The representative of the early project is Bitshares. It is a blockchain development platform that is scattered around the world, even if some of them are attacked, it will not cause the system to collapse. Anyone can freely transfer, borrow, etc. on this platform, or quickly build a centralized exchange based on this platform. In order to ensure stable value, Bit shares also require 3 times digital assets as mortgages. At present, Bit shares are okay.
Later, with the development of Ethereum and smart contracts, the 0X protocol came into being (token for short). This is an open agreement running in the Ethereum blockchain, a central exchange in the Ethereum ecosystem. The 0X protocol has attracted many investors. At present, financing has been completed, and open source software tools and infrastructure have begun. Of course, there are many competitors that are convenient for 0X. Ether Delta, IDEX, OASIS Dex, etc. are trying to provide similar functions. Moreover, 0X is based on Ethereum's smart contract system, only supports ERC20 tokens. If other smart contract public chains begin to rise, 0x demand will be reduced.
In addition, there are some teams that are entering the venue, such as the domestic road printing agreement, and English is loopring (LRC). They adopt a design similar to the 0X protocol, and also introduce a fast payment function similar to Lightning Network. It is characterized by trying to match multiple exchanges. The user's orders can be broadcast to multiple exchanges, which are jointly completed by different exchanges. Moreover, the user can still use account funds after ordering, and users who transfer funds or all of them are equivalent to partial or all. To some extent, the breadth and timeliness of the transaction is improved. However, this system seems to cause damage to the "power" of the existing exchange. Whether you can persuade everyone to play together will be a problem.
3. Summary
At present, there is still a long way to go to the construction of the central exchange. In 3-5 years, traditional exchanges will still be the main battlefield of digital currencies.
, in the future, letting decentralized digital currency get rid of the centralized 桎梏 is still worth looking forward to.
