Transparency of the underlying was not the issue. Anyone investing in this stuff could…
No-one knew what was in them -- the value was asserted by the ratings agencies and they were purchased based on expected rate-of-return.

The fact that transparency was an issue is also apparent right here, since nowhere near 65% of consumer mortgages failed. But no-one would buy because no-one could tell if any particular CDO was backed by anyone who was still capable of making payments.
With Ethereum and smart-contract based mortgage systems this completely disappears, since the blockchain broadcasts every single payment made in real-time and it is possible for anyone to simply look and see if whether defaults are rising or falling among the mortgages that underpin their collateralized securities.
