Created a new dat directory using dat(1); found a new file in there. Curious what it's for, and how it's formatted. Thanks!

Hey @yoshuawuyts, check out #93

This will presumably get documented in to a SLEEP DEP eventually (https://github.com/datprotocol/DEPs, to replace/update the old whitepaper), but I don't believe anybody is working on a SLEEP DEP yet. We could also insert a note on docs.datproject.org (FAQ?) if you submit a PR.

You might also find these other documentation-related issues helpful if you're doing an implementation working off the whitepaper, particularly if you want to support current (pre-hyperdb) hyperdrive:

• Current chunking: content-aware? de-duped? datproject-discussions#77
• Please clarify hyperdrive metadata "children"/"trie" encoding  #92
• Please clarify hyperdrive metadata "children"/"trie" encoding  #92
• Spec: how to delete files? #94
• https://github.com/bnewbold/geniza/blob/master/notes/crypto/notes.txt

That file has been there for quite some time.
