Ethereum: Can a validator include transactions with invalid signatures?

In the Ethereum blockchain, validators play a crucial role in ensuring network integrity and security. To achieve this, validators must include valid transactions in their blocks, which are then transmitted throughout the network. However, what happens if the validator receives an invalid signature on the transaction? In this article, we will look at whether the validator can include such transactions.

Yellow paper

According to Ethereum Yellow Paper (2.4 This means that if the validator receives an invalid signature of the transaction, it will still be included in the block.

Invalid signature case

Although yellow paper clearly states that validators should include valid transactions, there are situations where an invalid signature may occur. For example:

• A malicious actor could create a transaction with an invalid signature and send it to the node on the network.

• The node can get a transaction from an external source and try to add it to the local block.

Can a validator include invalid signatures?

Based on yellow paper, it seems that validators cannot include transactions with invalid signatures. The article states that validators must check the validity of each transaction before incorporating it into the block. This ensures that only valid transactions are included in the circuit.

However, this does not mean that validators cannot receive or confirm invalid signatures from other nodes or sources. In fact, many Ethereum developers and researchers have studied ways to handle such cases, such as:

• Implementation of additional verification mechanisms to determine invalid signatures.

• Using methods such as optimistic consistency to block the ability to add a semi -valid deal.

Conclusion

In conclusion, while yellow paper provides clear guidelines on how validators should include transactions in their blocks, this does not clearly solve the ability to include transactions with invalid signatures. However, many Ethereum developers and researchers have studied ways to deal with such cases, and it is possible that subsequent yellow paper updates will provide clarification on this issue.

After all, the ability of validator to include transactions with invalid signatures depends on the implementation and design of a special blockchain network. While there may be theoretically restrictions, validators are currently not able to include invalid signatures on their blocks based solely on the information provided by other knots or stakeholders.
