I don't think what you're saying here is correct. 'fake' transaction problem between counterparties aren't an issue and as I replied to your comment on the 1-5day settlement period in the GS r3 thread >> It takes some financial assets 3-5 days to settle That 1-5 days to settle isn't due to slow and disconnected systems though, which is what many looking from a tech perspective believe. Most financial transactions are matched in settlement systems the same day they are traded. The 3-5 days is for prefunding of underlying accounts, tear ups and other asset class idiosyncratic reasons.
