Bitcoin: Understanding the security question p2tr
As Bitcoin developers continue to improve their protocol for safe and effective transactions, the question draws attention between enthusiasts and researchers equally: What happens when the Bitcoin Transaction is sent using the P2TR command sequence (prepaid transaction)?
In this article, we will deepen the world of P2TR scripts and explore why some critics have expressed concern about their safety.
What are P2TR scripts?
P2TR scripts are a type of bitcoin transaction script that allows for quick and convenient payment processing. Unlike P2PKH transactions (RMD160) or P2WSH (Sha256), which use private switches to sign and check transactions, P2TR scripts do not require encryption or deciphered public key.
The problem: no public key
The decisive aspect of Bitcoin safe transactions is the use of a digital signature. The standard Bitcoin protocol uses a private key to retrieve a unique digital signature for each transaction using algorithms such as RMD160 (digital hash randomized hash) or SHA256 (HASH algorithm Safe 256). This ensures that the sender’s identity and the size of the transaction will be checked.
In contrast, P2TR scripts use a public key encoded in the Boch32M format. Although it may seem simple, it raises significant concerns about security. Without a public key, any attempt to check or audit transactions can compromise the entire system.
The equivalent “P2PK”?
As mentioned, some critics claim that P2TR scripts are simply a P2PKH (RMD160) version with the coding of BEC32M. In other words, they do not provide additional characteristics or security benefits compared to their P2PK counterparts.
Consequences and security concerns
The lack of a public key in the P2TR scripts makes them vulnerable to several security issues:
- Centralization
: If a malicious actor can cross and manipulate these transactions, you can access confidential information about the private keys of the users.
- audition : Without a digital signature or verification process, it is difficult to track the origin and ownership of the assets.
- Bifuerability : The security risks associated with P2TR scripts make them vulnerable to manipulation by external participants.
Conclusion
The lack of public switches in P2TR scripts has caused concerns among Bitcoin enthusiasts and researchers. Although they may seem a convenient solution, the possible security effects make it essential to reassess its design and implementation.
As developers continue to improve the Bitcoin Protocol, we can expect to see improvements in sequences of a safe transaction commands. Future updates may relate to these restrictions, guaranteeing the long -term resistance of our decentralized financial system.
