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. https://github.com/TierNolan/bips/blob/cpkv/bip-cprkv.mediawiki <https://www.avast.com/sig-email> This email has been sent from a virus-free computer protected by Avast. www.avast.com <https://www.avast.com/sig-email> <#DDB4FAA8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
