Systems that use a Bitcoin-like proof-of-work function are both:

1) Monumentally inefficient
2) Vulnerable to an attacker who wins the proof-of-work lottery most of the
time, like has recently happened to Bitcoin
<http://www.coindesk.com/ghash-io-never-launch-51-attack/>

Compounding this problem is the desire to prevent key compromise in
Bitcoin-like systems via the use of multisignature trust and trusted third
parties which sign-off on certain operations. This approach centralizes
authority, in which case a consensus-based system like Ripple with trusted
gateways could be used instead. If it were, it'd be much more efficient,
and arguably have better security properties.
