Bitcoin: CoinSelection: GetSelectionAmount: m_value or effective_value

Understanding Bitcoin Transactions: Conselection and Getselectionamount

The process of choosing Bitcoin transactions is a critical aspect of the protocol that allows miners to choose which transactions include the block. One of the key methods used for this purpose is
Cointelection , namely the ‘Getselectionamount ()’ method on the structure of outputgroup.

However, it seems that there is a problem with a code fragmentation that shows that m_value or ‘Effict_Valuecannot always be returned to' Getselectionamount () . Let's immerse yourself why this can be the case and how it affects the choice of bitcoin transactions.

When Baník called "Outputgroup :: Getselectionamount (), it basically requires a number of coins in each of the selected transactions. For various reasons, however, the return of the value may not be exactlym_value(actual amount), but more recently an approximation or representative symbol.

Here are some possible reasons why "M_VALUE or” Effect_value “may not return:

• If the selected transactions exceed this limit, the mine will have to choose a fewer coins or use another method to allocate the available space.

• Complexity of transaction : Some types of transactions (eg transaction fees) may require more complicated processing or validation, resulting in other overhead costs and potentially causing Getselectionamount () to return the value to The representative symbol instead instead of a symbol of a representative of the actual amount.

• Calculation of the difficulty of yield : an algorithm of difficulty in producing yield extraction is designed to ensure that each block has sufficient computing sources with profit. However, this process may introduce some coincidence and variability, which can lead tom_valueor 'Effe_Value' will not return exactly.

• Difficulty to set up

  : Without accuratem_valueor chefection_value, miners may try to diagnose problems related to the validation of the block or to correct the difficulty.

In order to relieve these risks, Bitcoin developers recommend that you use the following proven procedures when choosing coins:

• Check the return Getselectionamount () compared to the actual amount.

• Use a consistent and reliable method for distributing transaction coins.

• Apply additional inspections or validation to make sure that the selected coins are within appropriate limits.

Understanding these restrictions, developers can offer more stable algorithms for the selection of transactions and minimize potential problems in the bitcoin extraction process.
