If you want to query the transaction records on the main network, you can use Etherscan. However, if you build your own private chain, how should you query the transaction records

the answer is that you need to listen to the logs on the chain, save them in the database, and then query them in the database. For example:

< pre t = "code" L = "Java" > varaddr = & quot& quot;< br />varfilter=web3.eth.filter({fromB lock:0 ,toBlock:' latest', address:addr });< br />filter.get(function(err,transactions){
transactions.forEach(function(tx){
vartxInfo=web3.eth.getTransaction(tx.transactionHash);
/ / at this time, the transaction information txinfo can be stored in the database
})< br />});

Web3. Eth. Filter() is used to monitor the log on the chain, and Web3. Eth. Gettransaction() is used to extract the information of the specified transaction. Once the transaction information is obtained, it can be stored in the database for query

7. Note that Ethereum is 2.0 now. As of 13:57 on the 4th, the current deposit contract address of Ethereum 2.0 has received 1000098eth, and 31252 addresses have completed the mortgage of 32eth. With the increasing number of mortgage, the annual yield of mortgage will graally decrease. After the mortgage amount reaches 1 million eth, the current annualized yield is about 15.7%. Zhongyuan, a well-known exchange, has taken the lead in opening the mining channel of eth2.0 verification node, and then launched qeth. Users can invest their own eth in verification node mining and exchange qeth to obtain liquidity, and then participate in mining. Compared with the disadvantages of eth2.0, qeth has too many things: the liquidity is guaranteed, the user does not have to bear the technical cost, the threshold of participation does not need 32 eth as low as 0.1eth, the nodes are maintained by the platform, and the income is distributed according to eth2.0.

8. Opinion taking refers to children's ability to infer other people's internal psychological activities, that is, to understand other people's thoughts, wishes and emotions. The essential feature of view taking is that indivials are self-centered in their cognition, that is, they can look at problems from the perspective of others. Therefore, an indivial must first be able to discover the potential differences between his own views and those of others, and distinguish his own views from those of others. However, to distinguish one's own views from others is not to choose others' views. Only by making accurate inferences about others' views on the basis of differentiation can one really have the ability to choose views. The ability of opinion taking is developed under the stimulation of extensive social interaction and colorful social clues, which has an important impact on children's personality and social development
some contemporary developmental psychology theorists and researchers have developed Piaget's views on children's cognition and put forward various stage models to describe the development of children's view taking ability. There are mainly two theoretical models:
Flavell divides a series of cognitive psychological actions that occur when children adopt opinions into four stages according to the order of occurrence: 1. Cognitive evaluation of others has the possibility of different views (attitude, knowledge, etc.) from their own. Children realize that people have different views on a certain event or situation. 2. Need stage. Children realize that it is necessary to infer the opinions of others in order to achieve their goal of interpersonal communication, persuade others and win in the game. 3. Inference stage. The cognitive activities in this stage include all psychological activities except perception. The purpose of these activities is to infer the views of others in a particular situation, that is, character characteristics. 4. Application stage. Indivials apply their inferential information to subsequent behaviors, such as what to say and how to say to others
Salman used the dilemma story of "Holly climbing the tree" to study children's perspective taking ability. According to the children's reaction, Selman divides the development of view taking ability into five stages: stage 0: egocentric view taking. Children cannot distinguish between their own interpretation of events and what they believe to be true or correct. Stage 1: social information perspective selection (about 6-8 years old). Children are aware that others have different understandings and opinions. Stage 2: self reflective viewpoint selection (about 8-10 years old). Children realize that everyone knows that others have their own thoughts and feelings. They not only know that others have different views, but also can be aware of others' views. Stage 3: mutual viewpoint selection (10-12 years old). Children can view the interaction of two people from the perspective of a third party and a common friend. Stage 4: viewpoint selection of social and custom system (over 12-15 years old). Children recognize that there is a comprehensive view, and also recognize that "in order to accurately interact with others and understand others, each self should consider the common view of the social system."
