① What are the current development prospects of blockchain technology

Research strength has increased and research results have been significant

As of the end of 2019, my country’s blockchain technology The number of research institutions has reached 97. In addition, domestic universities have deployed blockchain technology research, strengthened the innovation of blockchain technology theoretical knowledge, and improved the blockchain technology research and development capabilities of universities. By the end of 2019, there were 24 universities in my country participating in strengthening blockchain technology research and development. The core technologies are mainly distributed in the aspects of consensus algorithm, cross-chain, underlying architecture and multi-chain.

Judging from the research results, in terms of consensus mechanism, my country’s consensus mechanism is gradually moving from a single algorithm to a hybrid consensus; in terms of cryptographic algorithms, cryptographic algorithms such as secure multi-party computation, homomorphic encryption, and zero-knowledge proof are continuously integrated and applied. ; Research on cross-chain technology and security technology has gradually become a research hotspot.

From the perspective of blockchain hardware, currently, the world’s most important digital currency mining equipment suppliers are all located in China, including Bitmain, Canaan, and Yibang Technology. Three mining equipment companies account for more than 90% of the market share.

From the perspective of industry applications, the financial industry is currently the industry with the most blockchain technology implementation projects and the richest scenarios, such as supply chain finance, asset certificate aromatization, credit reporting and risk control, etc.

China accounted for 60% of the world’s patent applications in 2019

With the tilt of national policies towards blockchain and the implementation of applications in various fields, blockchain-related patents have gradually gained Attention from all parties. Compared with 2018, the number of blockchain-related patent applications from Chinese enterprises has increased significantly in 2019. Among the top 100 global companies on the list, my country accounts for 63%.

The blockchain industry will be further standardized in 2020

In 2020, my country’s blockchain policies will continue to be favorable, standards and regulations will be more perfect, industry scale will continue to grow, and technology will continue to innovate and develop. , the application demonstration effect in key areas is accelerating. At the same time, based on the problems existing in the development of my country's blockchain in 2019, CCID Blockchain Research Institute proposed to speed up top-level design and formulation, establish a sound regulatory system, accelerate core technology innovation and research and development, promote third-party evaluation and certification, strengthen professional talent training, and accelerate promotion Six suggestions for implementation in various fields.

② What is blockchain

In the simplest terms, blockchain is a distributed ledger.

To understand what this means, we first have to look at its opposite: a centralized ledger. Because blockchain technology started with finance, we will also introduce it below using banks as an example.

The following is our process for using bank debit card transactions:

You can swipe your card to purchase goods in stores.

The merchant sends a statement to your bank for the agreed upon amount.

Your bank will verify that you may authorizeBuy.

The bank sends the money to the merchant.

Finally, the bank records this information in its ledger.

There’s a lot of technology involved here, but that’s basically it. The last step is important - the bank records all transactions made by the customer. This ledger goes all the way back to the first transaction the bank made.

This ledger is kept, maintained and regulated by the bank. You can read it in your online bank account, but you can't change it. The bank has complete control. If it decides to make a change, there's nothing you can do about it.

Crucially, if hackers were able to access a bank’s ledger, that could cause a lot of problems. They can change the account balance to make it look like certain transactions never occurred, etc.

This is why distributed ledgers are so cool.

Blockchain Network Visualization

If a bank operates on a distributed ledger, each member of the bank will have a copy of the ledger, and whenever any member of the bank When they make a purchase, they tell every other member of the bank.

Each member will validate the transaction and add it to the ledger (the added records are called "blocks"). This has some important benefits, as there is no centralized authority that can manipulate records. Hackers accessing one ledger won't be a big problem because other ledgers can easily verify it.

On the other hand, it requires a lot of work. In short, the second system is blockchain (at least in financial scenarios).

As mentioned above, blockchain is a decentralized list of transactions. If I send Xiao Ming 2 Bitcoins, I send a message to everyone in the network saying "I am sending Xiao Ming 2 Bitcoins" and they all record the transaction.

The future of blockchain, how will it change our lives?

One thing that is important about blockchain is that it is a public resource and no one really owns it because everyone owns it.

Blockchain is not just science fiction. We don’t need to understand the mechanism behind this technology, but you do need to understand that it may completely change our lives in the next 20 years.

This may sound bold, but remember, 20 years ago we were browsing the Internet on Netscape, using state-of-the-art Motorola flip phones, and buying our first DVD players. At that time, if we imagined that a computer could be held in our hands and that we could buy cars, make payments, and watch movies, it would have been considered a fantasy.

Although the impact of blockchain may not be as obvious as the Internet, nor as tangible as mobile phones, blockchain will effectively solve many worries in daily life. Such as intermediaries cheating people, transaction delays, etc.In our current lives, middlemen are everywhere and we take them for granted as a part of life. If one day these intermediaries cease to exist, you will find that the world will become a different place.

Imagine that by 2040, blockchain may become a mature and widely used technology. When one day you can't live without the blockchain just like you can't live without the Internet now, you will be surprised to find that this decentralized accounting technology has simplified the complexity and become a part of your lifestyle

③ Will the blockchain industry decline in 2019?

No
Although the currency circle is now in a bear market, blockchain does not become useless without cryptocurrency.
The blockchain industry has developed very rapidly in recent years. Blockchain technology is increasingly appearing in front of people. More and more blockchain applications have been implemented. Blockchain electronic invoices, blockchain Traceability, blockchain finance, etc. Talents in the blockchain industry are also very scarce. Many universities in my country have opened blockchain courses to provide talents for the blockchain industry.
The development of a new technology will inevitably encounter setbacks, and the blockchain industry will develop even stronger in the future.

④ What fields has been covered by blockchain in 2019?

Digital finance, Internet of Things, intelligent manufacturing, supply chain management, digital asset transactions and other fields. According to querying blockchain news, as of 2019, blockchain has covered digital finance, Internet of Things, intelligent manufacturing, supply chain management, digital asset transactions and other fields. The blockchain is actually equivalent to a disintermediated database, which is composed of a series of data blocks.

⑧ How much is the pi currency worth in RMB and when?

When is the pi currency worth in RMB? This is mainly determined by third-party transactions. , instability will also occur with economic fluctuations.

Generally, cryptocurrency holders have two options to convert their cryptocurrency holdings into "Real" money (or "cash-out"):

Buy goods and services directly or exchange their cryptocurrency for government-issued currency (e.g., USD, EUR, etc.) on a cryptocurrency exchange. Use your money directly Use Pi to purchase goods and services. Pi Network is building a peer-to-peer marketplace where our members will be able to purchase goods and services directly with Pi. We aim to begin trialling in-app transfers of Pi in the fourth quarter of 2019.

Exchange Pi for government-issued currency on cryptocurrency exchanges. Pi’s core team has no control over when cryptocurrency exchanges (like Binance, Coinbase, Kraken, etc.) decide to list Pi. However, Pi will be able to list Pi on the project’s first Phase 3 (i.e. Mainnet) for trading. At this point, exchanges can choose to list Pi. In the meantime, Pi's core team is currently focused on implementing our technical plan (see our white paper) to reach Phase 3.

⑨ What will be the development trend of blockchain in 2019

As an industry insiderScholars, what I see is the survival of the fittest, the survival of the fittest. Those unreliable and purely deceptive blockchain projects will die faster in the cold winter, and even if they don't die, they will slip away. Companies that are truly capable and earnestly research blockchain technology will have a higher probability of surviving and then take off in the next bull market.
In terms of currency prices, the overall price in 2019 should still be in a bull market, because bears are long and bulls are short.
There will be more breakthroughs and developments in technology and business applications in 2019.
