I can't push this transaction. Always getting Exception: Code: -26, Error: mandatory-script-verify-flag-failed (Non-canonical DER signature)
i don't know why you are receiving that error but it is because your transaction is not signed. it contains 104 inputs and only 3 of them are signed and the rest don't have any signature!
No, I didn't buy a wallet.dat, I am doing some tries with dormant addresses using the SIGHASH_SINGLE vulnerability for P2PKH addresses.
what vulnerability?!!!
