Ethereum enhancement

2. Since its establishment, Beijing Digital Capital Technology Co., Ltd. has been committed to studying how to effectively solve the instry pain point of "traditional instry + blockchain". Various projects emerge in endlessly in the blockchain instry, and the technology has been innovated repeatedly. At present, the hottest topic is "stable currency". Beijing digital technology has also been supporting the stable currency system, bringing new development opportunities for the blockchain instry
what is stable currency
stable currency, as its name suggests, is a cryptocurrency with stable value, and its exchange ratio with legal currency remains relatively stable. Because the exchange ratio between legal currency and goods and services is relatively stable, the ultimate anchor of stable currency is goods and services, that is, the actual purchasing power
stable currency originated from usdt (benchmarked US dollar) issued by 2014 bitfinex established tether limited. The opportunity for the birth of cryptocurrency is that the mainstream currency accounts for the vast majority of the market value, but the price fluctuates violently, which makes the liquidity of cryptocurrency market decline. In this case, in order to protect their assets, investors need to find a better way to store value, so the stable currency market arises at the historic moment
the essence of stable currency is a kind of accounting voucher
modern banking system is based on the central bank at the bottom, commercial banks at the top and financial technology companies at the top. Their basic prototype mainly comes from the double entry bookkeeping which was born 500 years ago. Even after so many years, the banking system is constantly developing and changing, but its core is the centralized account system, which depends on the central bank. When we transfer money from one account to another, we are actually making account changes through the bank. When using stable currency for transfer and remittance, it completely transfers from its own account book to another account book. The essence of stable currency is a kind of bookkeeping voucher
some people would say, isn't Alipay also using block chaining technology? On this basis, Alipay upgraded and upgraded the account book, which is two different schemes based on the stable currency issued by block chain technology. You see that money is transferred from a Alipay account to another Alipay account, but it is still operated in the central bank's account system.
why is stable currency the future of blockchain
at present, stable currency is mainly used to provide channels for legal currency to enter the cryptocurrency world, help currency people avoid risks in transactions, and provide payment services for blockchain application projects. Although the current digital currency market is not too optimistic, but the cryptocurrency project is in constant development. The number of stable currencies on the market has already exceeded 50, and is still on the rise. 2019 is bound to be the year of stable currency outbreak. How did stable currency break through in the wave of digital currency? Why is stable currency the future of blockchain? This involves how stable currency affects the blockchain instry
tickets for users to enter the market
after "94" in 2017, China banned the market circulation of cryptocurrency, restricted banks and other financial institutions as payment platforms or channels, and many countries also restricted the circulation of cryptocurrency. But there are still a lot of users who want to enter the market, they will choose over-the-counter trading and trade through the community. But because of the uncertainty, opacity, small scale and other problems, OTC has some trading risks. Usdt, a stable currency anchored to the US dollar at a ratio of 1:1, has become a supplementary scheme for some new funds
the insurance medium of user assets
in the weak market, the price of token fluctuates greatly, and traders do not want to take risks or leave the market. In the case that the trading platform does not support legal currency trading pairs, it is almost the only choice to use "stable currency trading pairs" to exchange for stable currency
the emergence of stable currency is the proct of a special historical stage e to the contradiction between the rapidly developing demand for token investment and the restriction of legal currency admission by regulation. The more serious the price fluctuation of mainstream currency is, the more valuable the existence of stable currency is
"trade as settlement" is an efficient payment and settlement tool
blockchain technology has great value in the field of payment and settlement. With the emergence of JPMorgan JMP, many banks around the world have begun to explore how to use blockchain technology to issue stable currency. The "stable currency" issued by these banking giants is essentially using a convenient and efficient settlement network based on blockchain technology. The more financial institutions and customer groups join the network, the greater the value of the settlement network
as JPMorgan Chase, IBM and Facebook have revealed that they want to issue currency, stable currency has once again set off an upsurge. After the strong fluctuation of usdt in the second half of 2018, it was derided as "unstable stable currency" by many people, so Pax, tusd, GUSD, etc. followed closely. Seizing the market quota of stable currency is very fierce for a time, but the fierce market competition means that there is not much space left in the market, and no matter how much stable currency there is, it seems meaningless. Then the major exchanges began to launch their own platform currency. JPMorgan Chase, IBM and Facebook also entered the market. The situation of stable currency also changed greatly. Facebook and JPMorgan have both broad user base and far-reaching economic impact, and issuing currency will certainly have inherent advantages. Beijing Digital capital technology, which is deeply engaged in the study of the significance of stable currency, has made practical application of stable currency in postal, supply chain finance, lottery and other fields. It is understood that the world's first African blockchain lottery will also be released in the near future. In this way, we can certainly expect to stabilize the currency market.

1. bitcoin

the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system

2. Litecoin (LTC) is an improved version of digital currency inspired by bitcoin. It was designed and implemented by a programmer who worked in Google. It was released on November 9, 2011. Lightcoin and bitcoin have the same implementation principle in technology, but the creation and transfer of lightcoin is based on an open source encryption protocol, which is not managed by any central organization

extended data

characteristics of bitcoin currency:

1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom

2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution

6. From bitcoin to Ethereum, it seems that more and more institutional traders are interested in accumulating Ethereum for long-term benefits, because Ethereum is also a store of value

1. Ethereum: a better value accumulation target

for many years, accumulating bitcoin has been the main way to store the value of cryptocurrency. Investors use bitcoin as a sharp weapon against the economic crisis. However, institutional traders are now also interested in Ethereum

in the 2020 annual review report of coinbase, it is noted that institutional customers are more and more interested in Ethereum. The reason is related to how investors evaluate Ethereum ecosystem
