Bitcoin: Is the scriptSig spending an PayToAnchor output expected to always be empty?

The script editions and Payanan choir editions: a sensitive balance

The most recent introduction of new P2A outputs (Payment-to-Anadon) in Bitcoin has curiously awakened the type of these scripts on the type of these scripts. In particular, we examine whether “script -dig -dig editions” are always empty.

Understanding the script SIG expenses

In Bitcoin, a script SIG spends that it is responsible for paying a fee for the development of a transaction. The SIG script contains information about who or what the fee has paid. However, this does not necessarily mean that the script is actually connected to any associated money fund.

P2A outputs: a new era of simplification

The introduction of P2A outputs marks a significant deviation from traditional Bitcoin transactions. In contrast to regular P2PKH addresses (Public Key Key Hash), for which a “scriptpubkey” has to unlock the transaction and transmission funds, P2A outputs have an optional “script -dig” component. This new format promises to simplify the process of reducing payments.

The script -sig spending problem

Now that we know about the script -sig -output status, let us go into whether it can be expected that it is always empty. The reason is simple: if someone has paid a fee with a P2A transaction, they did not necessarily give out their own funds. In other words, several wallpoons could be involved in the payment process, each of which contributes to the same P2A output.

This raises an interesting question: Script -Gangen" Always the same0x0000000000000000000000000000000000000001 ‘, as some may expect?

The answer

In short, yes, it is possible that “script -dig -dig editions” can be empty in certain cases. Here is the reason:

• Several wallets can contribute to the same P2A output.

• Some transactions may not have a corresponding script at all (e.g. when using a special “Paytoanchor” (P2A )ade.

• The existence of other items with scripts that output different amounts of coins can lead to empty values ​​of script -sig editions.

However, it is important to note that the P2A standard is still based on the concept of script -sig editions for the development of transactions. If a wallet receives a payment of an external source (e.g. a P2A transaction or a PayToanchor address), you normally spend your own funds that are assigned to the “Script -IG ‘component”.

Finally

It is not always expected that “script -dig -dig editions” is empty, but there are scenarios in which this could occur. In order to alleviate these risks, Bitcoin developers and users should be aware of the potential for several wallets that contribute to the same P2A output or other wallet-specific script-SIG values.

If we understand how the new P2A outputs work and how the effects of your design are, we can better navigate the world of Bitcoin payments and opportunities.
