❶ What is blockchain technology and how it changes business and financial models

Blockchain technology is a distributed ledger technology. It allows multiple participants to jointly maintain a secure, transparent and immutable record on a decentralized network. Blockchain technology was originally designed for the digital currency Bitcoin, but is now widely used in many other fields.

The core features of blockchain technology include:

Decentralization: Blockchain has no central control agency, and data is distributed on various nodes in the network, which makes it decentralized. The centralization feature reduces the risk of single points of failure.

Transparency: Transaction records on the blockchain are public to all participants, and anyone can view these records. This helps increase trust and reduce the risk of fraud.

Immutable: Once a transaction is recorded on the blockchain, it cannot be easily modified or deleted. This guarantees data integrity and security.

Smart contracts: Transactions on the blockchain can be automatically executed to implement "smart contracts", which automatically execute corresponding operations when specific conditions are met. This helps simplify complex business processes and reduce costs.

Blockchain technology has had a profound impact on business and financial models, which is mainly reflected in the following aspects:

Reducing costs: Blockchain technology can reduce intermediary links and reduce costs. Transaction costs and operating costs. For example, by adopting blockchain for cross-border payments, remittance fees can be significantly reduced.

Improving efficiency: The automation and smart contract features of blockchain technology help improve the efficiency of business processes, reduce manual intervention, and reduce error rates.

Enhance trust: The transparency and non-tamperability of blockchain technology help to establish a reliable trust system, reduce the risk of fraud, and provide better protection for commercial activities.

Innovative business models: Blockchain technology has spawned many new business models, such as decentralized finance (DeFi), digital asset trading, supply chain finance, etc. These new business models have brought disruptive changes to existing industries.

In short, blockchain technology, as an emerging technical means, is gradually changing the landscape of business and finance. With the continuous development of technology and the in-depth promotion of applications, blockchain is expected to have a more extensive and far-reaching impact in the future

❷ What is the prospect of blockchain

Applications of blockchain It has extended to many fields such as medical health, education, charity, social management, and finance. The biggest advantage of blockchain is that it truly completes the construction of credit in an anonymous society, bringing new opportunities to many fields, thus making various innovative applications possible. . The current blockchain is equivalent to the Internet 20 years ago. It is in its preliminary stage. In the future, it will definitely become a major part of the social economy and be used to benefit the people and society. Please wait and see!
Blockchain uses distributedAn intelligent peer-to-peer network that identifies, disseminates and records information in a database, also known as the Internet of Value. The concept of blockchain was first proposed by Satoshi Nakamoto in his paper "Bitcoin: A Peer-to-Peer Electronic Cash System" published on the Bitcoin Forum in late 2008.
It is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be an untamperable and unforgeable distributed ledger.
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 the security of data transmission and access. A new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and manipulate data.
Blockchain Investment
Blockchain investment is indeed one of the hottest investment methods in today’s society. Although blockchain seems to have just started, as such a novel existence, it It is indeed very unique. Many people don’t know what blockchain is. They only know that blockchain mining can make money, so they follow it in a fog. But to achieve a truly safe investment, I suggest that everyone still Understand it first, prepare well before taking action, and don’t fight an unprepared battle.
Blockchain technology does have huge room for growth in the future. Many people believe that it will be able to subvert many existing industries in the future. This is very important. This is the source of all your confidence. If you If you don’t recognize the value of blockchain from the bottom of your heart, then you are likely to be affected by some negative remarks and even doubt the entire industry, which will affect your entire decision-making and judgment.
If you just want to play casually or test the water, the chance of success is very small.
Once you are determined, be prepared and spend all your precious energy on research. When investing, you must do your homework! Never invest money without knowing what the project is about.
Finally, the blockchain is a new industry after all. It is currently in a mixed situation, and of course there are scammers. Therefore, when we invest, we must be careful and do not accept what others say. Bright eyes.
In addition, I still have to say that investment is risky, so you must be cautious!

❸ Big data, artificial intelligence and blockchain are coming, are HRs ready?

Big data, artificial intelligence (AI) and blockchain are currently hot topics , these emerging technologies will always change our lives in the future. So, for HR practitioners, what impact will these emerging technologies have on HR?
Big data
Big data refers to a collection of data that cannot be captured, managed and processed within a certain time range using conventional software tools. It requires new processing models.It can produce massive, high-growth and diversified information assets with stronger decision-making power, insight discovery and process optimization capabilities.
In the past, when recruiting personnel, a competency model was first established based on theory. This model is based on certain experience, logic and assumptions. It has not been tested in practice to see whether it is really correct and effective. Instead, it pays more attention to the logical inferences before and after. However, the core of big data is to use massive data to predict what may happen in the future, rather than to establish causal relationships. It is derived from past practice. Google can be said to be a pioneer in using big data technology for recruitment. Google first asks all current employees to complete a questionnaire with hundreds of questions, and then uses big data analysis to derive a set of mathematical models to find suitable talents based on this set of mathematical models. In this way, Google no longer only judges the ability of job seekers based on diplomas and grades, but can also find job seekers who have great potential in schools and grades that are not very good.

Big data is currently used in HR, mainly to digitize the behavioral characteristics of the company's existing personnel, and to establish competency and quality models through big data and algorithms. The difficulty in application lies in how to digitize behaviors and how to establish mathematical models.
Artificial Intelligence
Artificial Intelligence, abbreviated as AI in English, is the study of the laws of human intelligent activities, the construction of artificial systems with certain intelligence, and the study of how to allow computers to complete tasks that previously required human intelligence. Competent work is to study the basic theories, methods and technologies of how to apply computer software and hardware to simulate certain intelligent human behaviors. For example, our common smart search is a type of AI application.
Predictive algorithms and machine learning are rapidly emerging as a tool to target the best candidates, and many AI+ recruiting companies have emerged. Use AI to quickly assess the personal qualities of job seekers and draw conclusions by examining word preferences, micro-movements, psychological emotions, and social media terms. AI tools can also be used to screen resumes and search databases to save recruiters time and automatically market jobs to qualified candidates. AI recruitment software can be used in the early stages of recruitment to narrow the scope of candidates. In the later stages of recruitment, employers will often choose to communicate face-to-face with job seekers and make human judgments. This software increases recruitment efficiency and reduces screening bias.

At present, the application of AI in HR is mainly in external recruitment software services. Building AI-based recruitment internally requires a lot of investment in costs.
Blockchain
Blockchain is an encrypted ledger of digital records that are organized into a set of data, called ‘blocks’, and distributed over a network. These blocks are located on servers called "nodes" and are connected together like a chain. Whenever a new transaction occurs, the blockchain is authenticated on the network. Therefore, authentication of each node is required to add blocks to the chain.Blockchain creates trust because a copy of the chain showing each transaction is held by the entire network. This is a method of decentralizing data, sharing it only with the people you want to share it with, and the data can only be modified or deleted by its owner. It's encrypted and nearly impossible to change unless you are the verified owner of that data.

The immutability and openness of information on the blockchain make this data storage method very credible. In the past, we needed to spend a lot of time verifying the authenticity of education certificates, the validity of skills, and even needed to verify relevant information through external background check agencies. Similarly, job seekers are also afraid of leaking personal information and are reluctant to disclose relevant information. Blockchain technology can help recruiters verify candidates' credentials in a highly secure manner and reduce the possibility of certificates being altered or forged, while also effectively protecting job seeker information. In this way we will reduce the time spent on information verification and improve recruitment efficiency.
At present, the application of blockchain is just an idea and concept. It requires the participation of a large number of people and organizations to build data in this way, so that it can be applied in the HR field in the future.

❹ Take stock of the top ten hot words of the Internet of Things in 2021

Brother Bin will work with you to take stock of the top ten hot words of the Internet of Things in 2021 and create a new future in 2022

2021 is an extremely difficult year for the Internet of Things. At the beginning of the year, Tuya, an IoT platform to B business, went public at a huge loss; at the end of the year, Didi America, an IoT shared travel to C business, delisted. For more than half a year, ofo's deposits were not refunded, and they were still trying to make ends meet; for a whole year, production, supply, price increases, stockpiling, and out-of-stock were suspended around chips, and many IoT integration companies were in desperate need of survival.

2021 is an extraordinary year for the Internet of Things. Behind the normalization of the epidemic are 5G telemedicine/cloud supervision, non-contact prevention and control/time and space companion reporting, autonomous driving/delivery/retail and other Internet of Things technology and scenario support. The core of the Sino-US trade war is the right to speak on international standards such as 5G/6G, the right to formulate rules for the operation of the digital economy, the global footprint of the digital industry, the support of new OS platforms and killer application ecosystems, etc. The battle for new technologies + new applications + new models.

Brother Bin will take you to sort out the Internet of Things in 2021 under the top ten hot words.

1. Non-contact epidemic prevention

From the beginning of the year to the end of the year, the epidemic has become normal, and everyone is always preparing and fighting. In the process of epidemic prevention, the non-contact technology of the Internet of Things has contributed a lot.

The non-contact channel integrates health code, infrared temperature measurement, identity verification, self-service disinfection, etc., and the whole process ends in 3-5 seconds.

Non-contact logistics can be realized through self-unloading of unmanned trucks, AGV + robotic arms, and self-service disinfection by robotic arms.The entire process of unmanned transportation and distribution of goods.

These non-contact scenarios all require the Internet of Things end (temperature and humidity/robot arm/AGV/truck positioning, etc. collection), pipe (4G/5G/Wifi, etc.), cloud (various applications )ability.

2. 5G telemedicine/cloud supervision

Since last year, China Mobile has successfully implemented “5G telemedicine” in Wuhan Huoshenshan Hospital and many hospitals, collecting live videos, Environmental and patient status data help frontline medical staff share local medical data with remote experts to achieve expert remote diagnosis.

Doctors conduct consultations remotely, and online partners remotely watch the live broadcasts of Huoshenshan and Leishenshan Hospitals. For this reason, the term "cloud supervision" became a hot word on the Internet at the end of last year.

3. Autonomous Driving + Connected Vehicles

Autonomous driving in 2021 has taken another step forward amid ups and downs.

Tesla’s disputes continue and the risks of data collection are exposed. Major car manufacturers such as Wei Xiaoli, traditional car companies and BATH are severely lacking in cores and are under great pressure to deliver, but they are all working hard to innovate. Alibaba has enriched the unmanned delivery scenarios of Xiaoman Donkey, Xiaopeng has launched unmanned horse toys and unmanned aerial vehicles, and Huawei is constantly and actively adjusting its Internet of Vehicles strategy.

4. Cat1/NB-IoT+5G standard

On July 9, the International Telecommunication Union ITU meeting included my country’s NB-IoT in the 5G technical standard. NB-IoT is officially included in 5G standards, which is another manifestation of my country's leading international standards-setting organization's voice.

Also an ITU standard, Cat1, as the standard for 4G communication LTE network user terminals, gives full play to its advantages of low cost, low power consumption, lower delay, wider range and higher speed, and has been used in It has experienced explosive growth in the past two years.

5. Passive Internet of Things

Passive is the Internet of Things without power/energy source. The Internet of Things is very fragmented, and the scenarios are very fragmented. The types of sensors that need to be collected, power consumption requirements, and regional locations are all diverse and scattered. For this reason, sensors and IoT devices that can obtain their own energy are very important. Of course, solar energy and power conversion can be used as passive sources. The new passives that have made rapid progress this year are realized through electromagnetic/radiation conversion. It consumes less power than existing RFID, has wider application scenarios, and of course has greater market value.

6. Satellite Internet of Things

At present, the Internet of Things only covers 20% of the land, 5% of the ocean, and basically 0 in sky/space. The satellite Internet of Things is through satellites. Turning satellites into base stations must complement the remaining network coverage with future 6G, quantum communications, etc., and continue to improve transmission speed and bandwidth.

7. Dual Carbon + Carbon Tracking

To realize the country’s dual carbon strategy, carbon tracking is a key link. What is carbon tracking? It is to monitor carbon emissions and understand where carbon is emitted, how it is emitted, and how much it is emitted. Only with carbon tracking can we have better management of carbon emissions, recycling, and transactions. To monitor carbon emissions, we use the various sensing, transmission, cloud and data analysis capabilities of the Internet of Things.

8. Digital Virtual Human + Digital Twin + Metaverse

Come together. The motion capture and expression collection of the Internet of Things connect physical people (virtual human avatars) with digital virtual people; the end-pipe cloud of the Internet of Things connects digital twins of equipment, production lines, workshops, factories, parks, streets, cities and other objects , the scene entity and the digital body are connected; and digital virtual people + digital twins are the CPS world that integrates people + things, connecting people and things with the prototype of the metaverse.

At the beginning of the year, digital twins (digital twins) were in the spotlight; in the middle of the year, the metaverse became popular (Brother Bin checked through Moments and was invited to write a recommendation for the book "Metaverse" in early August, and then the metaverse Explosion); the explosion of digital virtual humans at the end of the year looks lively on the surface, and the Internet of Things is the lining of its technology.

9. Internet of Things Security

The delisting incident of Didi in the middle of the year can be described as a milestone event in Internet of Things security/network security. Didi uses Internet of Things technology to collect data from nearly 1 billion users and the location and voice information of the vast majority of the country for many years. If these massive amounts of data are not firmly in the hands of the people, national data will not be safe. Similarly, the more an IoT platform company is, the more it must be cautious and tread on thin ice in ensuring the security of IoT data on its platform and ecosystem.

10. Chip shortage

Finally, let’s talk about the chip shortage, because some chips are still in shortage. The prices of radar, dynamic control, and imaging chips for the Internet of Vehicles, as well as USB, network cards, and analog chips commonly used in IoT/5G scenarios have skyrocketed by 10 times, 50 times, or even 100 times. Natural disasters and man-made disasters are no longer clear.

If we don’t want to be strangled when it comes to chips, we must make domestic products to strengthen ourselves and the Chinese people to unite.

Brother Bin has three hopes for the Internet of Things in 2022:

1. Killer applications will no longer be put on hold. The killer application of the Internet of Things has been talked about for a long time, but it has been delayed. Brother Bin hopes that killer applications of the industrial Internet will truly emerge in 2022, especially in the three directions of 5G, industrial Internet, and Internet of Vehicles combined with vertical industries.

2. New technology concepts will no longer be divided again and again. Since the beginning of the year, countless people have been cut off by blockchain, quantum technology, digital twins, digital currency, NFT, virtual digital people, the metaverse... on the K-line of the stock market, in investment circles, and in pyramid schemes. Brother Bin hopes that in the coming year, the Internet of Things and VR/AR,The further integration of blockchain will further consolidate the digital twin base, support the construction of the metaverse framework, and promote the true implementation of e-commerce 3.0 (virtual live broadcast), digital virtual humans, and industrial digital twins.

3. Semiconductor chips are no longer competitive. Finally, I sincerely hope that in 2022, those who are still hoarding chips will make a certain profit and sell them as soon as possible. Remember: the sign of eating = the sign of death.

Luo Pang endorsed network 5G cloud driving (remotely controlling unmanned vehicles through 5G to realize driving) in this year's New Year's Eve "Friends of Time". He hopes that 5G cloud driving will become a new era. The killer app of the year.

❺ What is the Metaverse and what are its core technologies

The Metaverse mainly has the following core technologies: One is extended reality technology, including VR and AR, the second is that digital twins can mirror the real world into the virtual world, and the third is to use blockchain to build an economic system. The metaverse cannot simply be equated with video games, nor can it be equated with virtual worlds. It is creative play Open exploration and connection to reality.

With the explosion of the concept of the Metaverse, virtual digital humans have once again become the focus of public attention. Recently, A-Soul, the leading domestic virtual idol group developed by ByteDance and operated by Lehua Entertainment, caused a chain reaction due to the suspension of its members, bringing the virtual idol industry and its ecology to the attention of all walks of life again. With the fermentation of the idol group A-Soul incident, other virtual people who are one of the investments of the Byte family have also been pushed to the forefront.

It is understood that at the beginning of this year, ByteDance invested in "Li Weike", "Li Weike" and the team behind it: Hangzhou Li Weike Technology Co., Ltd. has also received much attention from the industry and media. focus on. Recently, Hangzhou Li Weike Technology Co., Ltd. launched two new virtual human characters: Lingxia and Xiaoke. The company stated that the new characters, together with Li Weike, will eventually be implemented in AR glasses products.
