Understanding events related to P2SH editions: Why do you find information in the field of script and witnesses
As a Bitcoin investor or user, you will probably know the unique functions of the P2SH (private 2 address -shash). These transactions are safer and private than conventional traditional, key base transactions. One aspect that can lead to scratching your head is the reason why some spending events contain information in script -sig and witnesses.
In this article we examine the details of the P2SH consumption events by examining what happens in these additional areas and how they work.
What are the scripts and witness fields?
In Bitcoin, the event consists of several fields that recognize it as a unique event. These fields include:
* Scriptsig : Contains a script (instruction set) that are used to carry out the function during event mining.
* Witnesses
: Serialized data structure that contains metadata about the event.
P2SH: Private Key -based transaction
To understand why P2SH transactions contain both scripts and witnesses, we have to look at P2SH. In P2SH, every private key (digital signature) refers to a certain script. When the user spends a coin from the wallet, the event includes a new script with a private key signature.
The resulting transaction edition contains several data structures:
* Scriptsig : The script that performs the action during the event. This manuscript is created by a private key that is assigned to the P2SH address.
* Witnesses (or
ELIN ): Further information about the event such as value, N (number of coins) and other metadata.
Why do some events contain both scripts and witnesses?
In some cases, expenses can be both script and witness fields. This is not normal behavior in Bitcoin or P2SH. However, there are some scenarios in which it can happen:
- Restoration attacks : In rare cases, the attacker can use the use of reinstallers to be used to inject a harmful code in the transaction crystal using a private key that is assigned to the field of script -sig. This enables you to manipulate the behavior of the event after its mining.
- The script honor : The attacker could have used a script (malware that hides the code) to hide his harmful script at the event. This would prevent the analysis and detection of mining workers or other security measures.
Diploma
Understanding the P2SH editions is for everyone who uses Bitcoin or place this cryptocurrency. Although the scripts and witnesses are standard components of the P2SH event, there can be unusual cases in which they occur. To avoid problems, it is important to be aware of these scenarios and take the necessary precaution in private keys.
If you look at the basics of P2SH events and understand why you contain both scriptrig and witness fields, you are better equipped to navigate the complexity of Bitcoin and make conscious decisions about your digital property.
