If Bitcoin actually brings about a degree public accountability and gets central banks using a common, open ledger, then
possibly the most opaque (ostensibly) public institution, adopting the most accountable and public innovation in data management? Nuh.
The funny thing about this is that cryptographers have been proposing hash chains to secure ledgers and other history for ~25 years, and been firmly ignored until something like Bitcoin that uses exactly that tech (plus Proof-of-work) got big enough to bring it to the attention of people like IBM.
Now that's interesting background. Which kind of suggests that the top cryptography guys don't end up employed in any kind of R&D management roles at places like IBM, which is kind of surprising.
Not really interested in this though, it's hardly going to be non-political or free market. Still betting that the best decentralised solution will prevail. At any given time.
