what is the size limit of data that can be stored in a transaction.

Question

I am investigating a use case for multichain. Wondering if a the data transactions we currently have could be stored or if they are too large. Today we transmit messages/files that could contain several MB of data.

Answer 1

We've tested this and the current limit is 8 MB. Note though that you always have the option of chaining multiple transactions together. I should add that you need to set the max-std-tx-size and max-std-op-return-size values high enough in the blockchain parameters in order to support this.
