Re: Researching to leverage Hashed-Timelock Agreements (HTLAs) paradigm for establishing atomicity between different DLT networks for asset swaps with full decentralization

Hi Evan,

Would like to quickly check with you on the questions below. Thanks!

1. Do you need that whole transaction to happen atomically or for the
balances to just end up that way?
    Nathan Aw: Probably the latter? Might be possible to have the different
transactions to happen atomically?

2. Also, do you need every party to maintain their own view of the state of
the balances, or is there a single central party that could track them?
    Nathan Aw: Ideally no central party. the decentralized network should
be and ideally be intelligent enough to identify these gridlocks and
address them automatically,          perhaps with the help of some
configuration?

Are there any of such capabilities in the roadmap?

Regards,

Nathan Aw
