⑵ How to develop a browser development solution based on blockchain

Blockchain browser is used to browse blockchain information In the main window, the content recorded in each block can be viewed from the blockchain browser. Usually digital asset users will use a blockchain browser to query the transaction information recorded in the block. The main function of the blockchain browser solution developed by Yingtang Zhongchuang is that it records in detail the confirmation process of each block and the generation and distribution process of digital currency, and completely records the transactions between each block. The circulation situation of digital currency, thus more completely and openly disclosing the stock, increment, turnover rate and other information of digital currency. The only thing hidden is the owner behind each block.

Extended information
1. Digital currency can be considered as a virtual currency based on node network and digital encryption algorithm. The core characteristics of digital currency are mainly reflected in three aspects: ① Due to some open algorithms, digital currency has no issuer, so no person or institution can control its issuance; ② Due to the determined algorithm solution, the total amount of digital currency is fundamentally fixed. It eliminates the possibility of inflation caused by the abuse of virtual currency; ③ Because the transaction process requires the approval of each node in the network, the transaction process of digital currency is safe enough.
2. The emergence of Bitcoin poses a great challenge to the existing monetary system. Although it belongs to a broad sense of virtual currency, it is fundamentally different from the virtual currency issued by online companies, so it is called digital currency. This article compares digital currency with electronic currency and virtual currency in terms of issuer, scope of application, issuance quantity, storage form, circulation method, credit guarantee, transaction cost, transaction security, etc.

Both Code and Read Contract under this tab page do not need to be connected to the wallet, only Write Contract needs to be connected to the wallet.
3. Option Write Contract tab, connect metamask wallet
After the metamask wallet is successfully connected:
After clicking the Write button, the metamask wallet will pop up, prompting that BNB needs to be consumed. Just authorize and confirm the consumption of BNB.
After the execution is completed, the execution results can be queried on the blockchain browser.
After the currency issuance is completed, the contract must be open sourced and the contract code must be verified to completely match the ABI and bytecode. Therefore, tokens need to be uploadedRelevant information to the BSC blockchain browser, including: contract name, compiler version, license, constructor parameters, etc.
The following are the operation steps of the open source contract code:
1. After the currency issuance is completed, record the transaction hash of the contract:
Query the hash details on the BSC blockchain browser:
