Standard gold blockchain video

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. digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency.

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

4. 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.

5. In general, you need to play 3-4 low-level skills first, and then use high-level skills to top them. If you belong to the same kind of skills, you can certainly top them. Just like if you have symbiosis, you can certainly top them. It should be noted that there can only be one manual skill, one automatic skill, and two or three auxiliary skills.

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. Yes, the real blockchain technology
has three characteristics: open source code, limited total amount and decentralization,
is the real encrypted Internet digital asset,
"as long as the Internet exists, network gold will never disappear"<

two trumps of network gold EGD:
1. As a kind of encrypted digital asset based on blockchain technology, EGD has clear property rights, limited total amount and decentralized Internet native attributes
2. The unique global EGD Customization Technology (coloredpoints / tag) is an advanced derivative protocol based on EGD data block.

9. Bitcoin itself has some "attributes" behind gold, but the way of implementation is very different.
