interface Attachment : NamedByHash
An attachment is a ZIP (or an optionally signed JAR) that contains one or more files. Attachments are meant to contain public static data which can be referenced from transactions and utilised from contracts. Good examples of how attachments are meant to be used include:
Calendar data
Fixes (e.g. LIBOR)
Smart contract code
Legal documents
Facts generated by oracles which might be reused a lot
