Is the eos memo field data that is attached to each transaction immutable and stored forever on the EOS blockchain?

1 Answer 1


Yes, the data is included in the transaction which affects its hash. If the data were to be removed, the hash of the transaction would change, disrupting the nature of the block chain.

  • The memo field has character limitations.
