Of course, no one likes these nasty accidents. Unfortunately, when the price of an asset is determined byReal-time Bitcoin transactions only a few factors, especially when these factors are not transparent to the public and are only in the hands of a few people, they are often more destructive. Therefore, by measuring the frequency of these types of events, we can get a good understanding of the performance of each asset in terms of tail risk. Please note that higher volatility does not necessarily mean higher tail risk, because if you have an expectation of the magnitude of the volatility, there will be almost no black swan. For example, no one complains about Bitcoin's 3-5% volatility today, but they curse the S&P 500 index for falling 3-5%. The losses caused by unforeseen outliers are the greatest.
1:1 reserve guarantee: According to Tether's CTO and co-founder Craig Sellars, users can wire US dollars through SWIFT to a bank account provided by Tether, or exchange USDT through an exchange. When redeeming USD, the reverse operation is sufficient. Tether's website claims that it will strictly abide by the 1:1 reserve guarantee, that is, for every USDT token issued, its bank account will be guaranteed by 1 USD.
Non-collateralized tokens: are the closest cryptocurrencies to decentralization. They rely on a model supported by smart contracts, which is set to emulate a reserve bank. Essentially, it will increase or decrease the money supply so that its final value remains as close as possible to the value of fixed assets (such as the US dollar). The main disadvantage of this stable digital currency is that it relies on a growing user base, otherwise, it would be impossible to maintain its link with it.
The two authors of the paper, StuartHaber and ScottStornetta, were both from academics. In the 1970s, Hubble graduated from Harvard University with a major in mathematics, then traveled to Paris Normal University and Stanford University, and finally completed a PhD in cryptography at Columbia University and became an expert in this field. Stoneta was about 10 years younger than Hubble, and studied at Stanford University in the 1980s until he received a PhD in physics. The chance that the two wrote this paper together was that after graduation, they both went to the then popular high-tech company Bellcore to do research and development1. Obviously, their profound mathematical backgrounds provided the foundation for the invention of blockchain and made this seminal paper on blockchain technology.
At the end of June, Bitrue was attacked by hackers and approximately $4.23 million in assets were stolen. The hackers found a security hole in Bitrue's platform that allowed them to gain access to the accounts of approximately 90 users. Subsequently, the hackers used the information they obtained and analyzed from these 90 accounts to successfully hack Bitrue's hot wallet. As a result, 9.3 million Ripple coins and 2.5 million ADA coins were stolen on the platform.
In addition, the GalaxyS10 series is also equipped with an AP (application processor) Exynos9820 developed by Samsung. Exynos9820 also includes a semiconductor-based cryptographic key management technology PReal-time Bitcoin transactionsUF, in fact, GalaxyS10 has enough security technology to safely store private keys.
2017 is also a year of unity. After Ethereum survived the hard fork of TheDAO, it successfully attracted widespread community attention. Both ETH and ETC have risen sharply in price, and ETH has also gained liquidity in all major cryptocurrency exchanges. Silicon Valley is very interested in this, and, compared to other trend-setting things that have emerged during the same period, it has particularly helped capitalize this asset.
The second type of people are institutional economists. I have also included law and economics here. Because although I was in law school, the teacher Su Li and his Ph.Ds in law school at the time were actually fans of law and economics. The founder of law and economics, Richard A. Posner (Richard Allen Posner) is a professor and jurist at the University of Chicago. He once analyzed the economic principles of various legal systems.
