blockchain could be fully
implemented across these parties, many of these attributes could be included in a smart contract, thus becoming a pre-trade requirement to execute an order rather than a downstream, post-trade check that requires

implemented in such a way that the copy of the
blockchain is itself spread over data centers in
multiple countries.
