Bitcoin: Is a Segwit format transaction with all inputs of non-witness program type valid?
Bitcoin: Is the Segwit format transaction with all invisible program inputs?
Entry
The introduction of Segwit, the extension of the Bitcoin protocol designed to improve the scalability and shortening of the transaction times, led many users to think about the importance of some transaction formats. In this article, we will examine whether the Segwit format transaction with all invisible program inputs (NWP) is correct.
What are the types of invisible programs?
Bitcoin programs relate to the functions or scripts that are not part of the witness’s transaction. They can include a user -defined code such as intelligent contract performance. The introduction of Segwit was aimed at improving the efficiency and performance of this type of transaction by reducing the amount of memory required.
What is Segwit?
Segwit is an update of the Bitcoin protocol designed to improve scalability and shorten transaction times. It allows you to create new types of transactions, such as Segwit-Spend, which can be used to send funds without enabling a full script. In addition, it allows more efficient performance of intelligent contract functions.
SEGWITS SPACE
When it comes to the correct Segwit transactions with NWP inputs, we must consider the following key aspects:
–
NWP inputs : Input of the invisible program must be in the form of a script. Types of scripts can include various options, such as Pay-to-Scile (P2SP) priority, Pay-to Witnes (P2BCCP).
–
Hashes script : Hash of the script inputs is crucial for determining its validity.
–
The length of the script
: The length of the script input may not exceed a specific threshold, depending on the specific type of transaction.
example Segwit transaction format
Let’s examine the example of the Segwit transaction format with inputs of invisible programs:
`
[Nversion] [marker] [flag] [txins] [txouts] [witness]
`
Here, TXINS 'is an input transaction indicator, Txoutsis an indicator of the output transaction, and the "witness" determines whether the shortcut or script should be taken into account.
is it important?
In order for this specific example to be valid in accordance with the SEGWIT standards, the following conditions must be met:
- NWP inputs have the form of scripts with specific types (P2SP, P2WP, etc.).
- The scripts for these input data match their appropriate "TXINS" and "Txouts".
- There is no incorrect or excessive length of the script.
Application
To sum up, although some transaction formats may be valid according to SEGWIT standards, the conditions listed above must be met to make sure that NWP input transactions are actually correct. This ensures proper performance of intelligent contract functions in the Bitcoin network.
Examples of use
Here is an example of the use of:
[NEVERSE] [MARKER] [FLAGA] [TXINS] [TXouts]
`
In this format, N represents the new version of the protocol. Other parameters indicate whether to take into account the shortcuts of the witness or the script for NWP input transactions.
`Bash
[1.0] [1] [0x00000000] [01]
This sample transaction with the entrances of the type of invisible programs (P2SP and P2WP) would be valid according to SEGWIT standards, assuming that the abbreviation values for these scripts correspond to their appropriate “TXINS` and” TXouts “.
note
The delivered format is a simplified representation, not a actual Bitcoin transaction. In practice, more detailed details are contained in transactions in the real world.
Application
In this article, we have examined whether the Segwit format transactions with all the inputs of the type of invisible programs are correct. Understanding the requirements for NWP input scripts in accordance with Segwit standards, users can create correct transactions that comply with these specifications.
