Signum can send arbitrary data or text messages to every transaction with up to 1'000 characters. The message can be public or encrypted so only the sender and receiver can read it. The message limitation is only by byte length. It can transmit data using any information structure or encoding, even with double encryption. There are no limitations to their format. Example transaction for a statement:
