En cuanto a la cuestión de la delincuencia, la situación actual ya no es la misma que hace unos años. Otras criptomonedas centradas en la privacidad, como Monero, son preferidas para actividades delictivas.
The hidden text was a digital battle cry. When Satoshi Nakamoto, the mysterious inventor of bitcoin, created the first 50 coins, now called the "genesis block", he permanently embedded the date and that headline into the data. Mr Nakamoto had decided it was time for something new: a decentralised cryptocurrency, free from the control of governments and central banks. TWELVE YEARS ago, on January 3rd 2009, a headline on the front page of the Times read: "Chancellor on brink of second bail-out for banks"—a reference to the British government’s efforts to save the country’s financial system from collapse.
Nakamoto is believed to have created the first blockchain database and has been the first to solve the double spending problem other digital currency failed to. While Bitcoin’s creator bitcoin
is shrouded in mystery, his Wizard of Oz status hasn’t stopped the digital currency from becoming increasingly popular with individuals, businesses, and even governments.
But other investors, such as the managers of huge pension funds, are likely to keep steering clear. If some portfolio managers have come around to investing in bitcoin, its value could climb further; at least, there may be a floor to its value. They typically invest in things that generate reliable future cashflows, like bonds or stocks, and tend to shy away from things that don’t, such as gold, other commodities—and bitcoin. If the masses pile in via an ETF, that would also maintain demand.
Many consensus algorithms adopt the Las Vegas algorithm to avoid the limitations imposed by FLP impossibility on deterministic and asynchronous networks. When these type of algorithms are used, BNB it is likely to reach a consensus decision in each round. These non-deterministic consensus algorithms involve the Las Vegas rule: A consensus is always reachable in a network, but the time needed to reach consensus may be unbounded. The probability (P) of reaching consensus within T seconds will increase exponentially with the increase of T and will get closer and closer to 1. The bitcoin consensus mechanism described later in this article also adopts this method. In fact, this method has been adopted by many successful consensus algorithms and is an escape hatch within the scope of the FLP impossibility. In addition, FLP does not exclude randomized algorithms like Las Vegas.
To process a variety of real and complex problems and challenges in distributed systems, many solutions have been developed based on theoretical guidance. This article does not describe the implementation details and specific differences of these algorithms. Instead, only a general introduction is given to make a comparison on the whole from a broader perspective.
Bitcoin is quite different , rather than being printed; it is discovered. The underlying mechanics can get complicated, but essentially, the government controls the production of money, paper money (fiat currency). This process of discovering new bitcoin is known as "bitcoin mining". The discovery of new bitcoin is one aspect of bitcoin mining while the other half is confirming transactions on the ledger . In the USA, bitcoin our fiat currency is created by the Federal Reserve and printed by the US Treasury. Bitcoin mining can be done on any computer capable of running the program, but is typically done on highly specified hardware, known as bitcoin miners. These miners can be plugged into computers USB ports, but are typically high-powered stand-alone units. Traditional economies are focused around the transactions that occur with fiat money .
Exchanges, however, are a different story. Imagine a bank in Iowa is robbed: the USD didn’t get robbed, the bank did. Perhaps the most notable hack was the Tokyo-based MtGox hack in 2014, where 850,000 bitcoins with a value of over $350 million suddenly disappeared from the platform. This doesn’t mean that Bitcoin itself was hacked; it just means that the exchange platform was hacked.
En una entrevista reciente en el Podcast Artificial Intelligence de Lex Fridman, el creador de la programación en C++, Bjarne Stroustrup, lamentó profundamente algunos casos de uso de su creación, especialmente el uso en Bitcoin.
The main reason is that PoW mining relies on physical hardware and electric power resources in the real world, which easily leads to Economies of Scale. Companies that buy 10,000 mining machines have more bargaining power than individuals who buy 1 mining machine, and even can develop their own mining machines with lower costs. And, mines with 10,000 mining machines have higher bargaining power over electricity charges, and can be migrated near power stations in countries and regions with low electricity charges, or even build their own power stations with lower costs. If price manipulation is not taken into account, the price of 1 coin and the price of 10,000 coins increase linearly. From this perspective, PoS may be fairer and more conducive to decentralization. The consequence is that the larger the organization, the lower the comprehensive mining cost, which is exactly what has really happened in the real world. However, the views on this issue are very controversial, and many people have put forward completely different views, believing that PoS is fairer and more conducive to countering the centralization trend than PoW. In contrast, PoS does not need to rely on hardware in the real world, and has no Economies of Scale advantage.
