DOCOODING INFORMATION: Demolition of Events
Sorana is a platform with a decentralized application with an open source (DAPP) that uses evidence of a consensus in the deposit frame (POS) and a new programming language tour called Rust. One of the key features of Solana is its ability to store Tieto programs in packaged Base58. However, separating this information and converting it to the number of transactions may be difficult.
Problem:
When you start the Sorana main network, it saves the program in a binary file. In order to use this information, you need to read the binary file and disassemble the appropriate information. Unfortunately, Solana does not offer any built features or application subscriptions that would do it directly.
Solution: “Solan -Program” Library Using
Fortunately, there is an open source library called “Solan-Program”, which offers a simple interface to interact with Solana. With this library, you can read and write program information in a packed Base58 format.
Here is an example of how you can use this library to break the amount of the event from Solan:
Install addiction
Install the desired addictions before you start:
`Bash
PIP Install the Solan Program Program
`
Code Example:
`Python
From Solan.Program Import ENTERN_POINT, Program_id
@entry_point (“get_account”)
Def Get_Account (program_id, Account_index):
Download program information from the file
Open (F “{program_id}/data”, “RB”) as a F:
Program_data = F.READ ()
Decode data -coded base58
Decoded_data = Solan_Program.decode_Base64 (program_data)
Disassemble the number of transactions (assuming it is stored on the last warranty)
Transaction_amount = decoded_data [-1]
Restore Transaction_amount
Start the income point when a new account is created or updated
Inpoint_point (“head”, Get_Account)
`
How does it work:
- They represent the program ID and current account index.
- Function Download Program Information from the file using
Open.
- Decoded data coded Base58 can be found in the variable
decoded_data.
- Assume that the amount of the event is stored in the last program of program information. In this case, we pick it up to the ‘decoded_data [-1]
.
- Finally, we return the amount of extracted trade.
Advice:
- Remember to editProgram_id
andAccount_index` account according to the Solan settings.
- This example assumes a simple program that records multiple events in the last information. Depending on your special use case, you may need to adjust this approach.
- Remember that this is a simplified example, and you should consider additional errors and safety measures while working with sensitive program information.
According to these steps, you can successfully decide on the amount of the event from Solan at the “Solan -Program” library.
