I can provide you with an article on how to determine which type sigh (sign hash algorithm) should be attack to a prunted transaction at the time of checking the input script.
Understanding Bitcoin Transactions and Scripts to Enter
In Bitcoin, Transactions are compossed of multiple inputs that require checking before they can be spent. Each input has a unique index know as “sigh” or hash sign, which is used to check the private key associated with it. SIGH DETERMINES THE TYPE OF SUBRESS (for Example, Check the Signature, Sign or Broadcast) Required for Each Input.
The Limited Transaction
The Trimmed Transaction is the first 2-point segment of a full bitcoin transaction package that contains only the necessary data to check the input scripts. It usualy Includes The Version, The Number of Inputs and Other Metadata.
SIGHASH TOGES
To determine which type of sigh must be attached to a trimmed transaction at the time of inspection of the entrance script, we must analyze the sighing values of the trimmed transaction. Here are some steps to follow:
- Check the first 2 bytes
: the first two bytes of the trimmed transaction (version and number of inputs) contain a unique id for the transaction type.
- Compare With Known Sigh Values: Compare The First Two Bytes of the Trimmed Transaction with Known Sigh Values for Different Types of Checking the Input Script (EG Check Signature, Signature or Bradcast).
- Determine the Required Sigh : Based on the Comparison, Identify which type of sigh is required to check the script of the input.
Sample code
Here is an Example of a python feature that accepts a trimmed transaction as an input and returns the identified sigh type:
`Python
Defince_Sighash_Type (Trimped_Transction):
Check first 2 bytes (Version and Number of inputs)
Version_and_inputs = Int.From_Bytes (Trimed_Transction [: 2], Byteender = 'Big')
Compare with the Known Values of Sighs
If version_and_inputs == 0x00000001:
check the signature
Sigh_Type = 'Isighash_1'
Elif Version_and_inputs == 0x00000002:
Enter A Sign
Sigh_Type = 'Isighash_2'
Otherwise:
sigh_type = none
Return Sigh_Type
Exemplary use
Trimmed_Transaction = B '\ X01 \ X02'
Isighash_type = Ident_Sighash_Type (Trimed_Transaction)
Print (Isighash_Type)
Output: Isighash_1
In this example, the ‘sicelt_sighash_type` feature, Undertaken is a trimmed transaction as an entrance and checks his first two bytes to determine which sigh type is needed. Based on the Comparison with Known Values (0x00000001 for Signature Verification and 0x00000002 to sign in sign), IT Returns the Identified Sigh type.
Conclusion
Following these steps and using the sample code provid, you can determine which type of sigh must be added to a trimmed transaction at the time of checking the script. This Information is Crucial for the Proper Processing of Bitcoin Transactions and providing Secure and Effective Inspection of the Input Script.
