1. The essence of a blockchain wallet is a private key, which is a random hash string. If you have the private key, you have the right to use the wallet. According to the storage method of the private key, it can be divided into cold wallet and hot wallet
cold wallet refers to the wallet where the network can't access your private key. Generally, it will take a notebook to record it. Although it avoids the risk of being stolen by hackers, it may also be lost
a hot wallet is a wallet that can access your private key on the Internet. Hot wallets are often in the form of online wallets, which are not easy to lose, but also have risks.

2. Today, I'd like to show you what you don't know about social workers...
in the embryonic stage
before 2006, social work in our province had not been included in the scope of work of Party committees and governments at all levels
with the increasingly frequent exchanges in the field of social services between Guangdong, Hong Kong and Macao, some social service institutions in Guangzhou began to explore social work practice since the 1990s. For example, Fengyuan street in Liwan District of Guangzhou cooperated with neighborhood counseling association to provide social work services to meet the needs of residents for community services; Guangzhou old people's home cooperated with Hong Kong Sheng Kung Hui to introce professional social workers to implement social work services for the elderly in homes; Some social organizations such as Guangzhou YMCA also try to introce social workers to accumulate practical experience< On the other hand, social work ecation started. Since 1999, South China Agricultural University, Guangdong Business University, Sun Yat sen University, Guangzhou University, Guangdong University of technology and other universities have set up social work programs
the social work service practice explored by social forces and the development of social work professional ecation have laid a certain foundation for the start of social work in our province< In 2006, after the Ministry of Civil Affairs held the national civil affairs system social work talent team construction promotion meeting in our province, our province quickly launched the pilot exploration, graally built social work demonstration areas in all parts of the province, strengthened the decision-making and coordination on major issues of social work, and steadily promoted the pilot work. Comprehensive promotion stage (2011 to present)
in 2011, the ninth meeting of the 10th CPC Guangdong Provincial Committee focused on strengthening social construction. The general office of the CPC Guangdong Provincial Committee and the general office of the provincial government issued the implementation opinions on strengthening the construction of social work talent team, and included "the number of social workers with certificates per 10000 people" into the evaluation index system of "happy Guangdong", The social work of our province has entered the stage of comprehensive promotion
the practice of social work has been graally deepened, and the service field has graally expanded from social welfare and social assistance to disability rehabilitation, drug control and ecation, community correction, employment assistance, employee assistance, dispute mediation, emergency response and other fields. The service area has expanded from urban areas to rural areas, and the service object has extended from children and adolescents, the elderly, the disabled to the floating population, the elderly and the disabled Disaster victims, women with special needs and other groups
social work professionals and social work service institutions are the main bodies that directly provide social work services. All parts of our province take the cultivation and expansion of social work talents and social work service institutions as the core of the development of social work, promote social work talents to take root in the front line to do service, and social work service institutions to build brand based on the long-term
judging from the government's emphasis on social work, Xiaobian thinks that social workers will graally appear as a profession, which is not only to distinguish them from the enthusiastic aunts of the neighborhood committee, but also to distinguish a mode of helping others and solve the existing problems in depth
social workers may be needed by more people in the future. If you have a social worker card at this time, it will be even better.

4. People who play digital currency know that everyone's wallet account has a private key. If you lose the private key, all the property in the wallet will no longer exist, so losing the private key is a terrible thing for friends who play currency. In addition, the person in charge of an encrypted digital currency exchange in a foreign country said: "it is the iron law of the blockchain world to recognize only the private key but not the person. With the current computing power and technology, it is absolutely impossible to dece the private key from the address. If it is feasible, all the addresses on the whole blockchain will lose security, and the assets on the blockchain will lose their meaning. "

6. Although
has completed payment in the early days of mobile payment, it has been through the input of payment password or fingerprint. But now Ma Yun's Alipay has opened a quicker and more convenient way, that is, brush face payment. P>
Alipay has already done the payment method of face recognition through camera. We have to wonder that the progress of high technology brings people convenience and quick, which is really very attractive, so that people do not need to take out the mobile phone operation.
there is no need to worry about this. In fact, it's just like using a mobile phone to brush your face and open your mobile phone. You can't and can't unlock your mobile phone just by using people's photos. Of course, people who are curious about this will take photos to do experiments, but this photo is not their own
someone took out a picture of Ma Yun's face and scanned it. They thought that he would brush his face successfully or that some of Ma Yun's eggs would happen. However, no matter how many times he did it, it didn't work. It just showed that he failed to brush his face. In fact, the payment wire has been very stable, and the payment security we are worried about has been taken into consideration by the technical personnel and is now in use, so we can use it safely
