Ethereum: Can a validator include transactions with non -valid firms?

In Ethereum blockchain, validators play a decisive role to guarantee the integrity and safety of the network. To achieve this, the validators must include valid transactions in their blocks, which are then transmitted throughout the network. However, what happens when a validator obtains a non -valid transaction firm? In this article, we will study if a validator can include such transactions.

Yellow paper

According to Ethereum’s yellow book (Section 2.4), the decision of the validator to include a transaction in its block is based solely on the validity of the transaction itself, not on the information provided by other nodes or interested parties. This means that if a validator receives a non -valid transaction firm, it will still be included in the block.

The case of invalid signatures

While the yellow document explicitly establishes that validators must include valid transactions, there are situations in which a non -valid firm may occur. For example:

• A malicious actor can generate a transaction with an invalid firm and send it to a node on the web.

• The knot can receive a transaction from an external source and try to add it to its local blockade.

Can a validator include non -valid signatures?

According to the yellow document, it seems that validators cannot include transactions with non -valid firms. The document establishes that the validators must verify the validity of each transaction before including it in its block. This guarantees that only valid transactions are included in the circuit.

However, this does not mean that validators cannot receive or validate non -valid firms from other nodes or sources. In fact, many developers and researchers from Ethereum have studied ways to deal with such cases, such as:

• Implementation of additional mechanisms to verify non -valid firms.

• Use of techniques such as optimistic sequence to allow partially valid transactions to the block.

Conclusion

In conclusion, although the yellow book provides clear instructions on how validators must include transactions in their blocks, it is not explicitly dedicated to the ability to include transactions with non -valid signatures. However, many Ethereum developers and researchers have studied ways to deal with such cases, and the future updates of the yellow book provide clarifications about this.

After all, the ability to include transactions with non -valid firms depends on the specific implementation and design of the Blockchain network. Although there may be theoretical restrictions, it is currently not possible for validists to include non -valid signatures in their blocks based only on the information provided by other nodes or interested parties.
