Identification of P2TR output types in Bitcoin
As a developer working with bitcoin transactions, you may have encountered types of outputs SRIPTSPUBKEY that can be difficult to distinguish. One this type is P2TR (wooden root root). In this article, we will study how to identify the types of P2TR outputs and provide guidance on how to distinguish them from other transaction scripts.
Understanding types of output outputs
Bitcoin transactions use different types of Scriptpubkey outputs to present different types of transactions. Here are the main types of results:
- Payment for wood (P2TK) : represents a payment made at an external address.
- Payment for the address (P2TR) : represents a payment made directly from one external address to another.
- Payment of Privateyey (P2TP) : represents a payment made from an external address to the personal key of an individual.
Types output outputs and P2TR
In the context of the P2TR output, you probably encounter transactions with Scriptpubkeys, which are not necessarily the roots of the pay for wood. In order to identify the P2TR outputs, we need to examine the structure of Scriptpubkey of the transaction more closely.
Here are some key features of P2TR output scripts:
* Prefix Pay-to-Address (P2TR) : The first few bytes of Scriptpubkey usually show whether it is P2TR or other type.
* Script code : The following bytes contain the actual script code for the transaction.
* Sum : The amount to be sent is usually represented by the following fields:
+ 1: shows that production is an incoming payment at an external address.
+ 0: shows that production is a direct payment from one outside address to another.
How to identify P2TR output types
To identify P2TR output types, study the first few bytes of Scriptpubkey and search the following:
- P2TK prefix : Check that the transaction starts with
0x6a1e ..., showing the root for a tree payment.
- script code
: Check that the script code is not a direct payment at an address or private key, and is more recently a payment from one external address to another.
Examples and tools for codes
To help you identify P2TR types of outputs, here are some examples of Scriptpubkeys:
- P2tk:
0x6a1e ... 0x5b85f9c4
- P2TP:
0x5d43 ... 0xB84ef3e1(private key to public key)
- P2tr:
0xa7ad ... 0x0e56ba8c
You can use tools like “Bitcoin-QTor Wallet-Cli` to visualize the script code. These tools allow you to check the structure of Scriptpubkey and identify the type of transaction.
Conclusion
In this article, we studied how to identify P2TR output types in Bitcoin transactions. By looking at the first few bytes and script code of Scriptpubkey, you can distinguish the roots of the payment for wood (P2TK) and other types of output outputs, such as payment for the address (P2TR) or Pay-Privatekey (P2TP). This knowledge will help you write more efficient and effective scripts for working with bitcoin transactions.
