That appears to be a script that includes an OP_RETURN opcode followed by some encoded data. OP_RETURN is an opcode in the Bitcoin scripting language that allows users to attach arbitrary data to Bitcoin transactions.

The encoded data following the OP_RETURN opcode in this script is not immediately recognizable to me, so it is difficult to determine exactly what it represents without additional context or information. However, it is likely that the encoded data represents some type of message, identifier, or other information that is relevant to the Bitcoin transaction in question.
