Query: Lightweight Selective Disclosure for Verifiable Documents on Blockchain   To achieve lightweight selective disclosure for protecting privacy of
document holders, we propose an XML format for documents that can hide
arbitrary elements using a cryptographic hash function and salts, which allows
to be partially digitally signed and efficiently verified, as well as a JSON
format that can be converted to such XML. The documents can be efficiently
proven to exist by representing multiple such structures as a Merkle tree and
storing its root in blockchain.
  We show that our proposal has advantages over known methods that represent
the document itself as a Merkle tree and partially hide it.
