How to query a blockchain
but the third party intervention also has many disadvantages:
- high transaction cost (a certain handling charge)
- Privacy exposure (the third party needs to provide the information of both parties in order to verify the information)
-...
imagine that if the third-party organization is removed and the two parties trade directly, how can the transaction take effect? The emergence of blockchain technology is to solve this problem. Blockchain is based on the principle of cryptography rather than trust mechanism, which makes the two parties reach an agreement to trade directly and publish it to all witnesses.
Blockchain is an important concept of bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
the data on bitcoin blockchain, which we call the data on the chain, generally includes: bitcoin active address, new address, continuous active address, reactivated address, transaction volume on the chain, number of transactions on the chain, TSP, transaction transfer fee on the chain, large amount transfer, mining difficulty and other data
we generally query the data on some blockchains through the blockchain browser, Bitcoin's more commonly used blockchain browsers are:

The relevant certificates can be issued online for the data of blockchain storage and network forensics through easysaving. Through the record number on the certificate, the blockchain query can be concted directly through the official website of easysaving and relevant arbitration commission, including the preservation subject, preservation time stamp, Guangzhou Internet court evidence number, blockchain hash value and other relevant information
1) if it's just "blockchain", the direct network can find a good interpretation of "blockchain network"
2) if it is "blockchain technology", the network also has a good interpretation, and all walks of life are also trying to combine with blockchain technology in new fields. Maybe in the future, blockchain technology will be used correctly instead of being used to deceive people
3) if it is "blockchain information", you can go to all kinds of blockchain media or financial media, and almost every day there are relevant blockchain instry information and news reports. Such as: Babbitt, coin you finance, blocknet, golden, daily, etc
4) if it's "blockchain audio", you can go to Himalaya FM, litchi micro class, qianchat and other platforms. For example, the audio related to "voice of money", "Yu Lingxiong", "Wang Feng" and some other financial media blockchain is also good, with various dry goods and in-depth analysis
therefore, the above four points are all related to blockchain. It depends on your choice.

for those who care about this book, green is here. I'm really sorry, because there are so many green things ring this period, so it can't be updated in time. Please forgive green. When green has finished all the things, it will come to update at the first time. After all, green is the first time to write a book, but also an amateur author, so you can also cool the difficulties of all cool green. Green is here. Thank you very much. Please continue to support...
please accept
put the program calling this WebService into an independent thread a, and then create another thread B for timing. Thread a and thread B share a variable responseok
start the thread B before calling WebService in thread A. After successful return, set responseOK=true.
when thread B starts, it will stop timing if responseok = = true. If the timing exceeds 20 seconds, it will terminate thread a and return an error message
it seems that if the server times out when calling WebService, an exception will be triggered. Just intercept this exception.
Users can query the relevant information stored on the blockchain by inputting the record number on the certificate through the official websites of easy security, notary office, Arbitration Commission , including security subject, security timestamp, security hash value, Guangzhou Internet court evidence number, relevant block information, etc. It can effectively ensure that user information, time and electronic data can not be tampered with, and ensure that the whole process can be traced, all data can be verified, and the whole link can be trusted< br />
