There was some discussion on the bitcointalk forums about using CLTV for
cross chain transfers.
Many altcoins don't support CLTV, so transfers to those coins cannot be
made secure.
I created a protocol. It uses on cut and choose to allow commitments to
publish private keys, but it is clunky and not entirely secure.
I created a BIP draft for an opcode which would allow outputs to be locked
unless a private key was published that matches a given public key.
