『一』What is the future of blockchain?

In 2018, blockchain-linked AI has become the hottest technical term, and more and more technology companies have announced their entry into the market. In the blockchain market and on the Internet, companies such as Xunlei, Renren, Baofeng, and Tianya have all taken blockchain-related actions. These companies have the same fate. They have all experienced prosperity, but after being impacted by the Internet entrepreneurship wave, they began to decline. Then they caught up with the hot spots of blockchain and began to try to counterattack.
Investment in the global blockchain industry is booming
According to the "In-depth Analysis Report on Business Model Innovation and Investment Opportunities in the Blockchain Industry" released by the Qianzhan Industry Research Institute, as of the end of April 2017, there were a total of 455 companies worldwide The blockchain company has received a cumulative financing amount of US$1.947 billion. Among them, the total investment and financing of U.S. blockchain-related companies is as high as 1.252 billion U.S. dollars, accounting for 64.3% of the global market; the total financing amount of Chinese blockchain emerging companies is approximately 114 million U.S. dollars, accounting for 5.86%, ranking second only to the United States in the world Second, it is growing rapidly.
The current overall survival status of the blockchain is good, with a survival rate of 87.25%. 47
of all the invested companies have been closed down, accounting for about 10.51%, and another 10 companies have been acquired. Due to changes in the competitive landscape of the Bitcoin market, some companies have been forced to close down. At the same time, some companies in the currency circle have gradually transformed into chain companies
Exploration at the national level has also begun. On March 23, the Department of Information Technology and Software Services of the Ministry of Industry and Information Technology announced that it would study and explore the application of blockchain in the industrial field. Previously, the Ministry of Industry and Information Technology stated that it was preparing to establish a national blockchain and distributed accounting technology standardization technical committee to explore the formation of a complete blockchain standard system to better serve the development of the blockchain technology industry.

『二』What is blockchain and how to make money with blockchain

Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
The ways to make money in the blockchain are as follows:
1. Coin speculation. Coin speculation is like stock speculation. Coin speculation is the lowest threshold for making money in the blockchain;
2. Vendors, district Blockchain is a global market. Like small traders, you can move from a low-price platform to a high-price platform to sell and earn the price difference;
3. Earn commissions for promotion. The blockchain method is to register first Exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates transactions, you can get a commission;
4. Mining, "mining" in Bitcoin is The accounting process;
5. Technical support, provided to some teams and enterprisesBlockchain technology support;
6. Open a trading website and charge handling fees;
7. Develop a wallet. The wallet is the infrastructure of the blockchain, just like the "Alipay" or "WeChat" of the blockchain "Payment";
8. Be a blockchain project or infrastructure equipment supplier.

『三』Is it good to buy a house in 2022? Do you have any plans to buy a house when the time comes?

First of all, there is no telling what will happen to China’s housing prices in the future.

Overall, in the next 2-5 years, the first and second tiers will fall by 15%, and the third and fourth tiers will drop by 30%. It is a high probability event. The first and second tiers have low holding costs, while the third and fourth tiers have limited purchasing power.

Nowadays, the leverage of residents is too high, and it is difficult for the state to increase wages even if they release funds. Basically, they are transferred to Leeks in the form of leveraged credit. The current situation is really unbearable. In the past few years, almost everyone who has enough basic money to make a down payment has bought a car. It is really dangerous to double the down payment.

Do the third and fourth tiers want to sell land? Of course they do. Is there a shortage of land? There is certainly no shortage. The new areas are all filled with land. The key is that this liability is not transferred to home buyers, and the government's land sales money is the bank's money. Again, there are too many stocks and I really can’t pick up the leeks. Recently, there have been more and more failed land auctions, and it is urgent to supplement finance with property taxes.

The essence of the first and second lines is the same, but the situation is slightly better, because the belief and holding cost are too low, and the two sides are still in a stalemate. Shenzhen and Shanghai restricted loan quotas, transaction volume dropped instantly, and the so-called big guys who bought the houses they just needed with full payment disappeared.

The introduction of the property tax has completely changed this equilibrium state. The guide price is obviously prepared for the property tax. Otherwise, who else would be so tired to provide a guide price for each community. If the real estate tax pilot is implemented quickly, it will be by the end of the year. If it is slow, it will be next year. It will definitely be launched. It will not be as harsh as everyone thinks, and it will not be like Shanghai and Chongqing before. Sell ​​the land when it is time to do so without delaying property taxes. After all, there will be a transition time, and the ratio between the two will be dynamically adjusted. At the same time, state-owned developers began to develop public rental housing. The country has many options for building public rental housing: a large number of vacant office buildings in the city center have been renovated, have good locations, and are endorsed by the state. It just depends on whether the country is willing or not. As the holding cost goes up, first-line housing prices will definitely loosen, but after all, if the first-line declines for a few years, a 15% drop is acceptable, which is nothing more than a return to around 2019.. So I personally feel that the first and second tiers will be an excellent low point to get started in 2-3 years.

It is estimated that it will take 2-3 years before the third and fourth tiers are fully levied, but if we have expectations, we will not be afraid of rising prices. The bubble in the third and fourth tiers is still quite serious. A 30% drop is considered good, but it may be cut in half directly.

This time we look at the determination and means to deal with double reductions. It feels really different.

Finally, no matter whether you buy it or not, just pay attention to the leverage. Yesterday I saw a post about buying a house in Chengdu, draining the down payment of both parents and borrowing foreign debt. It's so dangerous. Many people born in the 1990s have not realized that their parents' bodies are getting weaker day by day, and people will get sick as they get older. Being sick costs a lot of energy and money.

『四』What is blockchain technology? What exactly is blockchain?

In a narrow sense, blockchain is a way to store data in a chronological order. A chained data structure composed of blocks connected in sequence, and a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.

[Infrastructure]

Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer composition. Among them, the data layer encapsulates the underlying data blocks and related basic data and basic algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the core of the blockchain The basis of programmable features; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.

Extended information:

[Blockchain core technology]

Blockchain mainly solves the trust and security issues of transactions, so it addresses this issue Four technological innovations:

1. Distributed ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they all Can participate in supervising the legality of transactions and can also jointly testify for them.

The uniqueness of blockchain's distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure.Distributed storage generally divides data into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and has equal status, relying on the consensus mechanism to ensure storage consistency, while traditional distributed storage generally synchronizes data to other backup nodes through the central node.

No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically speaking, the accounts will not be lost unless all nodes are destroyed, thereby ensuring the security of the accounting data.

2. Asymmetric encryption and authorization technology. Transaction information stored on the blockchain is public, but account identity information is highly encrypted and can only be accessed with authorization from the data owner. , thus ensuring data security and personal privacy.

3. The consensus mechanism is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.

The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be the computing power and the number of shares. Or other characteristic quantities that the computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result.

4. Smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to automate claims settlement in some standardized insurance products.

In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.

『五』 Energy Blockchain Research丨Four major blockchain development trends that are expected to become “evergreen trees”

Blockchain technology continues to develop and expand to adapt to the needs of the financial market and the Internet market, and continues to provide digital solutions for them. By integrating blockchain technology in Web3 technology, we are developing decentralized finance (DeFi) services and decentralized applications (DApps) to enhance the digital ecosystem.

Experts estimate that by integrating blockchain technology and solutions, banks can save $12 billion or more annually. linkThe United Nations also uses blockchain technology to address issues related to human rights violations, fund international humanitarian development, and promote environmentally friendly blockchain ecosystem innovation.

One of the challenges with blockchain trends is that they are fleeting because the industry is constantly evolving. Therefore, some companies and developers often have questions about the development of a certain blockchain project. However, after diligent research and analysis, we found that the following four projects have the potential to become “evergreen” blockchain development trends. What’s more, these four projects are actively providing blockchain solutions to developers in the decentralized finance and decentralized application industries.

1

Blockchain Applications in Enterprises

Developers who want to create high-quality decentralized applications can do so with Jelurida's flagship blockchain Solutions "NXT and Ardor" to build scalable applications that meet market needs. To put it simply, Jelurida is working hard to seamlessly connect physical companies and enterprises with the blockchain industry. Imagine, is a blockchain without practical application still a blockchain?

Futurecoin is the world's first open source blockchain platform that relies entirely on Proof of Stake (PoS) consensus. Proof of Stake is an algorithm based on Byzantine fault tolerance that eliminates computational loss in the Proof of Work (PoW) model and improves transaction security.

Developers can leverage the Futurecoin framework to build and save custom blockchain solutions and create reliable exchanges for tokens. On the other hand, AdoCoin’s sub-chain functionality allows organizations to build permissionless blockchain digital solutions and run smart contracts.

By using these solutions and Ignis, Jelurida has achieved some success. Unlike some blockchain companies, Jelurida has achieved all milestones in its development path and currently operates in several countries on three continents.

Currently, Jelurida has many real-life projects running on its platform, one of which is Cycle4Value, an environmentally friendly gamification system that can control traffic conditions and improve public health.

Gaming and Non-Fungible Token Development

Enjin is for blockchain developers in the gaming and non-fungible token industry is another promising advance that provides creative developers with the opportunity to create the next generation of decentralized software and applications. Enjin powers real-world projects in the medical, political, financial, and entertainment sectors, and is proud to provide blockchain solutions to millions of users. The project has a market capacity of nearly 45 million, more than 2 million wallets have been installed, and more than 1 billion assets have been created.

"Go! By Health Hero", one of the real-life projects built on Enjin, is a future currency-based solution that can promote the development of health-related projects and services. This project is currently very popular. Other projects include Microsoft's Azure Heroes, "Lost Relics" and "Age of Corruption" for gamers.

Currently, Enjin is deeply cooperating with the emerging future currency industry. It is expected that as the industry develops further in the future, Enjin will play an important role in the industry.

Speed ​​and data security

When a developer wants to create a decentralized blockchain service with scalability and reliability, Speed ​​and safety are the basic factors he needs to consider. Elrond has done just that, processing more than 10,000 transactions in one second, which is 100 times faster than Bitcoin and Ethereum combined.

Here are some of the “evergreen” trends we need in the coming years.

Elrond uses an adaptive state sharding mechanism to support fast verification and transaction processing. Like Jelurida, Elrond uses proof of stake to save resources and improve transaction security.

With over 90,000 active accounts and a large number of development projects, it’s no surprise that Elrond’s ecosystem valuation has jumped from $10 million to $500 million. Elrond operates in approximately 30 countries and counts more than 115 companies and startups among its clients.

Environmentally friendly system

Cudos is a broadband blockchain platform that provides blockchain projects with computing resources by integrating the computing resources of developers and users around the world. power. The platform serves as a network for developers to share and sell common resources, enabling reliable and scalable blockchain projects on the Internet. Developers can build and publish decentralized applications, mine cryptocurrencies and amortize network fees.

Gaming and non-fungible token developers and markets, including other related blockchain businesses, can leverage the Cudos framework to create high-quality and secure decentralized solutions and products. The Cudos ecosystem is committed to providing developers with cheaper, more convenient, reusable and environmentally friendly blockchain solutions; providing organizations with cloud computing-based blockchain solutions; introducing innovative solutions into the Web3 framework, Allowing developers to create the next generation of decentralized applications.

Cudos recently partnered with blockchain-based carbon credit company ClimateTrade to offset its carbon dioxide emissions. The world is currently experiencing the negative impacts of climate change, and businesses and individuals have a responsibility to quickly mitigate and ultimately reverse these impacts.

『Lu』 What does block mean?

Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained".

Each block contains the cryptographic hash of the previous block, the corresponding timestamp, and transaction data (usually represented by a hash value calculated using the Merkle tree algorithm), like this The design makes the block content difficult to tamper with. Distributed ledgers connected by blockchain technology can effectively record transactions between two parties and permanently verify the transaction.

At present, the biggest application of blockchain technology is digital currency, such as the invention of Bitcoin. Because the essence of payment is to "add the reduced amount in account A to account B." If people have a public ledger that records all transactions of all accounts to date, then for any account, people can calculate the amount of money it currently holds.

The blockchain is precisely the public account book used to achieve this purpose, which saves all transaction records. In the Bitcoin system, the Bitcoin address is equivalent to the account, and the number of Bitcoins is equivalent to the amount.

(6) Health Tree Blockchain Extended Reading:

Conceptual definition

From a scientific and technological perspective, blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming. From an application perspective, simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency.

These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for the blockchain to create trust. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is an important concept of Bitcoin.

It is essentially a decentralized database, and as the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each dataThe block contains information about a batch of Bitcoin network transactions, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

In the original English version of the Bitcoin white paper, the word blockchain does not actually appear, but chain of blocks is used. In the earliest Chinese translation of the Bitcoin white paper, chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.

The Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations" on January 10, 2019, which will come into effect on February 15, 2019.

As an important breakthrough for independent innovation of core technologies, the security risk of blockchain is regarded as a major shortcoming that currently restricts the healthy development of the industry. Frequent security incidents have sounded the alarm for the industry. To embrace blockchain, we need to accelerate the exploration and establishment of a security system that adapts to the blockchain technology mechanism.

『淒』 What new situations and problems will new technologies such as blockchain bring to trials

September 2018, the highest The People's Court issued and implemented the "Regulations on Several Issues Concerning the Trial of Cases in Internet Courts", which clearly stipulates that the electronic data submitted by the parties shall be collected, fixed and processed through electronic signatures, trusted timestamps, hash value verification, blockchain and other evidence. If tamper-proof technical means or certification through electronic evidence collection and storage platforms can prove its authenticity, the Internet Court should confirm it.
On January 10, the National High Court Presidents’ Conference was held in Beijing. The Supreme People's Court proposed to strengthen the protection of data rights and personal information, carefully study the new situations and new problems brought to the trial by new technologies such as artificial intelligence, big data, cloud computing, and blockchain, and serve the digitalization, intelligent transformation of the industry and the digital economy. healthy growth. In Internet cases, electronic evidence has become a difficult problem in Internet trials because of the difficulty in preserving, obtaining, and notarizing evidence.
Using blockchain technology, the platform can well solve the credibility problem of electronic evidence in the entire chain from generation and storage to notarization and proof: when uploading to the chain, the blockchain is used to ensure the originality of the stored evidence data. reliability and integrity; after uploading to the chain, each judicial node on the preservation chain is used to ensure the credibility and security of the data; during litigation, the evidence is directly passed to the Internet court to improve the efficiency of rights protection. The core advantage of blockchain is decentralization. By using encryption algorithms, tree structures and consensus mechanisms, trust relationships are established in decentralized distributed networks, and distributed multi-node encrypted storage of data is realized, creating an open The transparent, non-tamperable, verifiable and traceable technical system allows each node to simultaneously store certificates and jointly supervise, effectively solving the problems of poor reliability and low security existing in the centralized model.
Using its own blockchain technology and judicial service capabilities, the platform has launched application scenarios such as blockchain certificate storage, electronic signing, intellectual property protection, and Internet justice, helping users to issue easy evidence certificates and notarial certificates online anytime and anywhere. , notarized custody letter, digital copyright certificates, and also provides services such as blockchain traceability inquiry, verification and preservation, allowing users to directly query relevant information about blockchain certificates in real time through official websites such as notary offices and arbitration committees. These will provide evidence for certificates and rights protection lawsuits. Provide strong judicial support.
