Bitcoin Relay Options The difficult question: Deep diving into node decision -making

As the global cryptocurrency landscape continues to evolve, the debate on the decisions of the nodes and the possibilities of relays have become increasingly important. While knots have the power to decide which transactions in relays, arises a critical question: Can they have the choice of not allowed to not allow certain types of transactions from relay? In this article, we will investigate the reasons why the relay is allowed or denied specific types of transactions and exploring the impact on the decisions of the node.

Background: Node decision -making and relay options

Bitcoin nodes are responsible for checking the transactions and making decisions for breaking them. When a new transaction is transmitted on the network, it is done in several stages of verification before connecting the blockchain. Knots need to decide which transactions for relay based on their own policy and guidelines.

Allow relay options: Why is it a bad idea

While assigning knots for depriving certain types of transactions may seem like a convenient solution, there are important reasons why this is not recommended:

1
Unclear guidelines : Without clear guidelines on what makes spam or malicious transactions, nodes can fight to make deliberate decisions.

  • Network Stability

    Bitcoin: Why can't nodes have the relay option to disallow certain transaction types?

    : Allows of nodes disagree with specific types of transactions could lead to network instability, as all ecosystem may require some transactions.

3
Safety Risks : Failure to take certain types of transactions from relaying could pose security risks, such as allowing you to block spam transactions by properly addressing the underlying issues.

Why is this bad idea: P2TR_V1 Specifics

One special type of transaction that could cause concern is P2TR_V1 (previous transaction). This type of transaction contains an inscription spam where the previous output of these transactions is reused. In other words, this involves reuse of existing outputs to avoid charges or simplified processes.

By default, the nodes are expected to transfer all valid transactions, including P2TR_V1S. However, this approach might not be sufficient to prevent the inscription spam. In order to address this problem, the nodes may have to introduce additional rules and guidelines to distinguish legitimate and malicious P2TR_V1s.

Is there a bad idea to give a knot option to ban specific types of transactions?

While the idea of ​​letting the knots should not allow special transaction types may seem attractive, it is not a good approach to a number of reasons:

1
Lack of clear guidelines : Without clear guidelines for what makes spam or malicious transactions, nodes can fight to make conscious decisions.

  • Network Stability : Allows of nodes disagree with specific types of transactions could lead to network instability, as all ecosystem may require some transactions.

Conclusion

In conclusion, it is not advisable to have a convenient solution to the relief of unauthorized specific transactions from relaying, it is not advisable to have a vague guidelines, possible safety risks and clear requirements. Instead, it is advisable to follow certain protocols and guidelines for testing and broadcasting transactions.

suggestions

To maintain the stability of the network and prevent the inscription spam:

  • Introduce clear guidelines : Create strict rules and guidelines that make up the malicious or spam.

  • Use existing verification mechanisms : Use the existing P2TR_V1 verification mechanism that has been operating efficiently for years.

3
Continuously monitor and audit : Regularly review and audit node decision -making processes to ensure that they follow certain guidelines.
