Here is an interesting comment from R3cev:
"At R3, our team of engineers are in constant collaboration with the financial services professionals at our 42 member banks. Most of our work entails marrying requirements with development execution to satisfy the standards of our consortium.
Though we cannot claim a monopoly on expertise in distributed ledgers or capital markets, we have begun to eliminate certain approaches to any financial-grade software solutions. Upon examining the distributed ledger landscape, weve found that the most saliently unsuitable application of distributed ledger technology is also one of the most popular: colored coins.
Colored coins are Bitcoin transactions which carry particular meanings (...) and replicate the move fast and break things attitude common to Silicon Valley rather than being designed in a way that best addresses the problem they seek to solve. The multiple hacks on Bitcoin exchanges through the years attest (...) the inadequacy of this approach when millions, let alone billions, of dollars are at stake."Read the full report @
