SEP 15: Attachment Convention (created 3/8/2018)
- Sometimes there is a need to send more information about a transaction than fits in the provided memo field, for example: KYC info, an invoice, a short note.
- Such data shouldn't be placed in the ledger because of its size or private nature. Instead, you should create what we call an attachment.
- A Stellar attachment is simply a JSON document. The sha-256 hash of this attachment is included as a memo_hash in the transaction.
- Red Hat automation reducing workforce in companies/government/organizations, facilitates more secure data transfer (emails, documents, accounting, contracts, etc), could be used with SEP 22 (IPFS Support).
