1. This is the order of importance: BTC private key, wallet security password, BTC address
the private key is everything and must not be told to anyone
as long as there is a private key, you can re import the wallet and reset the wallet security password
a BTC account can have many addresses, so the least important one is the address. No matter how unimportant, you can't just tell others.

2. If you lose the mnemonic words in the digital currency wallet, it is almost equal to the loss of the private key. Mnemonic words are just a form of the private key that is easier to understand. If you lose the private key, it is almost equal to the loss of the digital currency in the wallet. With the current technology, it is impossible to crack it. Therefore, if you forget it, you can only recognize it. Change the wallet and back up the mnemonic words
3. 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. Indeed, there are blockchain wallets using this technology, such as IDC
wallet. In fact, mnemonics are another form of expression of the private key, which has the same function as the private key, mainly to protect your blockchain money

5. 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. Let's start with the conclusion: I can't find it
the reason why blockchain has anonymity is that there is no identity on it. Some of them only have addresses and private keys. To operate the assets on the addresses, private keys are the only and necessary conditions. As a blockchain user, the private key is everything. And in order to ensure the security of the blockchain, with the current computing power and technology, it is absolutely impossible to push back the private key from the address. If it is feasible, all the addresses on the whole blockchain will lose their security, and the assets on the blockchain will lose their meaning
how to solve the application problem with such a hard to remember private key? At present, the blockchain wallet has met the demand to a certain extent, and few people really remember such a complex private key to play with blockchain. Trusted third-party private key escrow institution is also a choice (in fact, it is very close to the concept of online hot wallet), and then the private key system combined with biometric technology can also be an exploration direction Fingerprint, voiceprint, etc.)
