Standard gold blockchain 6

1. Are you talking about Xincheng heritage gold, which was just listed in September this year? The gold bar is of au999.9 purity. The manufacturer has both the qualifications of London gold and silver Association (LBMA) and Shanghai gold exchange. It holds the proct qualification certificate of China Banknote great wall and is made by China Banknote Great Wall, a company of China Banknote Printing and Minting Corporation. Is it reliable for the banknote printing unit.

2. blockchain has developed in five stages
1. Germination stage: the real germination stage of blockchain was from 2007 to 2009. In 2008, a Japanese American with the pseudonym of Nakamoto first expounded a new fantasy report on electronic money in the form of a synonym on the cryptography discussion group, and bitcoin came out. As early as 2007, Nakamoto began to explore a series of new technologies to create a new currency. On October 31, 2008, bitcoin white paper was released, and on January 3, 2009, bitcoin system officially began to operate
the main technologies supporting bitcoin system include hash function, distributed ledger, blockchain and asymmetric encryption; It can be seen that these technologies build the initial version of the blockchain, and it can also be said that the blockchain is the underlying technology of bitcoin. During the three years from 2007 to 2009, bitcoin was an experimental stage in which a very small number of people participated, and the real commercial activities had not really started
2. "Geek" niche stage: here, "geek" refers to people who are crazy about Internet technology and take technological innovation as fashion and life. On February 6, 2010, the first exchange of bitcoin appeared. On May 22 of the same year, someone bought two hamburgers with 10000 bitcoins. On July 17 of the same year, the exchange Mt. GOx was established, marking the official inflow of bitcoin into the market. Nevertheless, the only people who can really understand and enter the market to participate in bitcoin trading are geeks who are keen on Internet technology. They discuss bitcoin technology on the forum, mine for bitcoin on their own computers, and then buy and sell bitcoin on Mt. GOx. Now these geeks have become billionaires
3. Market brewing stage: the price of bitcoin was $13 at the beginning of 2013, but on March 18 of the same year, the government of Cyprus closed the bank and stock market e to the financial crisis, which made the price of bitcoin soar, and the highest price rose to $266 in April. On August 20 of the same year, the German government confirmed the currency status of bitcoin. On October 14, China network announced the opening of bitcoin payment channel. In November, the US Senate hearing also confirmed the legitimacy of bitcoin. On November 19, the price of bitcoin rose to US $1242, forming a new high. Nevertheless, the foundation for blockchain to enter the mainstream social economy is not yet available, and the soaring price of bitcoin is only e to over optimistic expectations. The containment of China's banking system, the collapse of Mt. GOx and other events made the price of bitcoin continue to fall. At the beginning of 2015, the price of bitcoin has dropped below $200. From 2013 to the beginning of 2015, the public began to understand bitcoin and blockchain
4. The mainstream period of blockchain: on June 23, 2016, the United Kingdom left the European Union, the fifth nuclear test of North Korea in September, Trump's election in November and other events, the uncertainty of the world's mainstream economy led to the recovery of bitcoin with the function of risk aversion. The market demand was large, and the increase of trading volume made the price of bitcoin soar from $400 in 2016 to $20000 in 2017, The wealth effect of bitcoin and the transaction overflow caused by network congestion of bitcoin have led to the outbreak of other series of virtual currencies, as well as a variety of blockchain applications, resulting in the emergence of a large number of blockchain assets that are 100 times, even 1000 times and 10000 times, which has aroused the crazy pursuit of the world, Subsequently, the Chicago Mercantile Exchange launched bitcoin futures trading, marking that bitcoin has officially entered the mainstream investment proct series, and bitcoin and blockchain have entered the global attention
5. Instry landing stage: after the market frenzy in 2017, the virtual currency and blockchain have been adjusted in terms of market, supervision, cognition, etc. in 2018, returning to rationality. In 2017, many blockchain projects that follow the blockchain technology will graally die out with the cooling of the market, and the projects with real blockchain applications will be initially implemented. 2018 is not only the first year of the blockchain, but also a gold rush period for the blockchain. After the waves wash away the sand, what remains is relatively good gold
from the perspective of the history of blockchain development, blockchain technology is not yet mature and is currently in the growth period. The specific practical application of blockchain is only used in the financial field. It still needs a long way to go to apply blockchain from other instries. However, we should grasp the trend of blockchain and actively learn from the new field of blockchain.

It's worth it

the blockchain system is jointly maintained by all of us, and it does not need to specially consume human and material resources. The decentralized structure greatly reces the cost. At the same time, the disclosure of data makes it almost impossible to make false accounts. Blockchain takes mathematical algorithm as endorsement, and its rules are based on an open and transparent mathematical algorithm, which can enable people with different political and cultural backgrounds to reach consensus and realize cross regional mutual trust

in addition to building a monetary system, blockchain also has many application opportunities in the pan financial field. Based on the programmable characteristics of blockchain, people try to add smart contract to blockchain system to form programmable finance, which is represented by smart contract

extended data:

precautions:

the effective behaviors of users on the platform, such as consumption behaviors, are recorded on the blockchain. While confirming the rights, corresponding data rights and interests are allocated to users. OLO can be used not only to exchange goods and services in the whole ecosystem, but also to exchange with other mainstream digital currencies for cash. Such an incentive will encourage users to contribute more valuable data

small and medium-sized enterprises join the ecosystem through API interface, and use OLO to buy big users, big data and large traffic, so as to realize precision marketing and expand the scale of enterprises. In the whole process, user data is desensitized, so there is no need to worry about privacy leakage. Finally, a big data trading platform with shared interests and value appreciation between users and enterprises is built to bridge the business model gap between users and enterprises

as a token backed by data assets, OLO represents the value of the continuous precipitation of big data. The more precipitation of data, the more valuable it is, so OLO itself has value

Blockchain 4.0 is the landing of a large number of scene applications and the deep integration of multiple fields, such as blockchain plus artificial intelligence, supercomputing, big data, etc., which requires and promotes the upgrading of the underlying infrastructure construction, greatly improves its inclusiveness, carrying capacity and scalability, builds its solid ecological network system, and makes the blockchain value network radiate more scenes, Value is more reflected. The block chain structure is as follows:

as a new generation of public chain, SPG super gold puts forward its own innovation on the basis of absorbing the advantages of public chain in the past. Considering that Neo has its own unique advantages in solving the problems of low scalability, low concurrency and low transaction feedback of the public chain, and has achieved practical results, at the same time, in the super gold cryptocurrency SPG generation mode, it prefers the mining output mode under the more decentralized workload proof mechanism, Therefore, super gold creatively launched a two-tier structure combining transaction verification with Ethereum workload proof algorithm ethash, which separated transaction verification and block packaging synchronization, so as to better solve the problems of low scalability, low concurrency, low transaction feedback and block congestion of blockchain, At the same time, the smart contract system of super gold is more suitable for the development trend of current blockchain technology. The support of cross chain protocol for cross chain transaction can help build a public chain platform with higher universality, wider application range and more prosperous and stable ecology. Therefore, SPG super gold can be classified as blockchain 4.0 array

5. The gold token issued by digix is the gold in the digital asset world. It is a typical representative of asset token project. How can it be linked with gold
gold is the best choice for risk aversion. The gold token issued by digix is the gold in the world of digital assets, and its token, DGX for short, can play a role of hedging in the world of digital assets
How can DGX benchmark gold? It will be gold assets on the chain (that is: blockchain) operation. For example, if you have a kilogram of gold ready for sale, you can cut the gold for sale, but it is too troublesome and easy to cause loss. You can also send 1kg of gold to Singapore for LBMA to verify the gold. After the verification, the certificate of ownership of gold assets will be issued to you
the digital certificate can be converted into 1000 DGX tokens, i.e. 1 DGX token = 1 gram of gold. The circulation efficiency of gold has been greatly improved. Similarly, when you need to extract gold, as long as you have the corresponding token, you can replace it with a certificate to extract gold.

In 1991, the Journal of cryptography published an article by S. Harper and w. stonetta, which discussed the method of adding time stamps to digital documents. In 1992, the same group of people discussed how to increase efficiency. This is the origin of blockchain technology. In 2008, the "blockchain" created by people or groups under the pseudonym of Nakamoto Tsung by bitcoin has a more idealistic color exclusive to the Internet

as one of many solutions of distributed computing, the most significant feature of blockchain compared with other distributed computing is that there is no need for administrators. For this reason, blockchain has paid a huge price in efficiency

Secondly, since digital currency is likely to become an important form of payment for sovereign currency in the future and contribute to the global use of sovereign currency, digital currency and gold are complementary and symbiotic. Blockchain provides a window to observe the real exchange rate and interest rate of sovereign currency. If we need to make the world generally accept the digital currency of sovereign countries, we need to first generally accept the credit currency of sovereign countries. As an ancient and widely accepted credit collateral, gold is obviously an important part of sovereign state reserves. With the impact of digital currency on traditional settlement system, the importance of local currency value will rise

especially with the explosive growth of global negative interest rate bonds, the number of credit collateral that can stably support the value of local currency is decreasing. At present, whether negative interest rate can last is a controversial topic in the academic circle. We tend to think that negative interest rate itself is a short-term phenomenon, and in the long run, it must be settled once and for all. In the process, as a traditional safe haven asset, gold is bound to have more space, and the trinity of gold (credit support), sovereign currency (credit medium) and digital currency (circulation means) will also be the international strategy of sovereign currency

the ideal of blockchain has failed, but the application of blockchain has just begun. The gold instry and gold should play an active role in this wave and contribute to RMB internationalization and instrial upgrading

7. Poof, this project calls itself national endorsement. Known as blockchain 4.0, it's just boasting B
now we are all talking about DAPP, parallel chain, side chain, super node, blockchain 3.0, and the 4.0 has come out, which is an air currency project, or air currency is not.

8. There is a popular folk saying: "the one who collects the debt is the grandson, and the one who owes the debt is the Lord", which vividly refers to the old problem that it is difficult to collect the debt and ask for the debt. Among these difficulties, the most difficult is that the debtor maliciously evades the debt and plays missing, which is also known as "running away";. In view of this kind of runaway phenomenon, small make up for the majority of creditors to give a move

there are two ways for debtors to run. The first is that the debtors really have no ability to repay. Under the pressure of all kinds of creditors, they have no choice but to hide and run. Xiaobian suggests that the debtors should give the other party enough time, and there is no need to look for them, because even if you find them, you can't pay them back, on the contrary, you force the other party to take risks

the second way for debtors to run away is to escape with money. Many debtors go against their conscience, hide and run with a lot of money that doesn't belong to them, and live a luxurious life like an emperor all day long. Then this kind of debtors is the object we creditors need to make great efforts to find. We can start with the other party's relatives, friends and social circles, and use the loose outside and tight inside method to find out. As we all know, no matter how much a person hides, he will not lose his social circle. We can start with the people he often contacts before, and wait for the hare. If it's really inconvenient, you can use a third-party investigation agency to find out for you

here I would like to say that if your debtor belongs to the second group, it will inevitably bring you a certain amount of money loss, because it takes a lot of manpower, energy and financial resources to find a person. There is no good thing in the world that you can get without effort, only you are prepared to find a failure, Only in this way can we sum up the experience in the continuous failure and finally find out the person who runs away successfully<

Xiaobian found a runaway old girl for a friend before. It took him half a year to succeed. The main reason for success lies in his firm belief that he will never give up until he reaches his goal. Nothing is difficult in the world. It's only a matter of time to find out the runaway debtor as long as you don't give up.
