** Understanding the error “Script-Script-Verify-Flag.

When trying to check a SchnorR signature for a bitcoin transaction, some users may find an error known as “non-matatorial-screen-verify-flag (Schnorr’s Invalid Signature)”. This problem may occur despite the successful checking of the signature with a valid script flag.

The question: Invalid Signature

In Bitcoin, a SchnorR subscription is used to verify that a sender to transmit a specific transaction. When a user creates a schnorr subscription, he specifies which public key in the sender’s portfolio should be used for the signature. The signature itself contains additional information, such as input data and expected output (ie the transaction hash).

The script flag is an important component of a Schnorr subscription. It specifies how the user wants to spend the coins for the transaction. A non-Mandatary-Script-script-script-script error occurs when the script flag is present but not used correctly.

Possible causes of error

There are several reasons why you can find this error, despite the successful verification of your Schnorr signature:

• Inconsistent script flags : If the script flags in the sender’s wallet do not correspond to the expected entry data, it may cause an invalid signature.

• Invalid input data : If the input data used to generate the signature do not correspond to the expected value, it may also lead to an incorrect signature.

• Incompatibility of the script flag

  : The script flag must be present and specified correctly for a valid SchnorR signature. However, if the flag is absent or has incorrect values, it may cause problems.

Alternative solutions and solutions

To solve this error, it may be necessary:

• Check that the script flags : Make sure the sender’s portfolio script flags correspond to the expected input data.

• Check the input data : Make sure the input data used to generate the signature correspond to the expected value.

• Check that there are inconsistent script flags : Check that the script flags are not confused.

Example Code

Here is an example of how you can create a schnorr subscription and check it using the Bitcoin-Schnorrl-Line tool:

`Bash

#!/bin/bash

Create the public key of a sender

pk = “your_public_key_here”

Set the input data for the transaction

Input_Data = “Your_INPUT_DATA_HERE”

Create a schnorr signature

schnorr_signature = $ (bitcoin -schnorr -txin <(echo "$ pk") --Txin <<< "$ input_data")

Check the signature with the expected script flag (1)

Verifier_Sript_flag = 1

Subscription = $ (Bitcoin-Schnorr -Txin <(echo "$ pk")-txin <<< "$ input_date"-script-verify-flag $ verifier_script_flag)

Check for errors

If [$? -NE 0]; then

ECO “Error: Invalid Schnorr Signature”

other

Echo “Success: Checking the Schnorr Subscription with valid script flag ($ verifier_script_flag)”

Fi

Transmit the transaction using the signature verified

TX_HASH = $ (Bitcoin-Cl Send-TXID <(echo "$ schnorr_signature")

`

Conclusion

The error “S-Script-Script-Verify-Flag (Invalid Schnorr Invalid Signature)” may occur despite the successful verification of a SchnorR signature. By understanding the possible causes and working with possible solutions, you can solve this problem and successfully transmit your transaction using the verified subscription.
