[Jsdsi-users] Re: <What's the correct way to send over Proof?>

[Sameer A. <aj...@cs...>]

You can transfer a Proof as a Sequence (using proof.getSequence).  But we
should probably add support for transferring it just as a Proof.  The
reason I didn't in the firts place is because Proof isn't actually an
official SPKI/SDSI datatype---it's specific to JSDSI.
