In a message from February 24, 2014, Tamas Blummer raises a question regarding the spam limit of at least 5430 satoshis when the script is OP_RETURN. Blummer expresses concern that it may be possible to create cheap spam through this method. In response, it is clarified that OP_RETURN outputs are provably unspendable and therefore not included in the UTXO set. The client conducts a check and handles TX_NULL_DATA outputs separately, ensuring they are not considered dust. Tamas Blummer notes that it currently costs 5430 satoshis to create an output. Wladimir, another user, responds by stating that if transactions like this are not abused and there is a need for more space, the limit can always be increased in future versions. It remains unclear whether the same spam limit applies when the script is OP_RETURN, but the original poster expresses concern about the potential for cheap spam.
