securing DB after a sync with the chain

[urbien]

A recent massive banks breach is notable for not stealing account data, but for manipulating data, specifically account balances, to a loss of at least $300M, likely close to a $1B. This could be prevented in the future with the blockchain.

But we need to be careful, when loading data into corporate DBs we lose the benefits of the blockchain.
We need to see if we can port some of the blockchain principles to our DB structures and/or continuously verify them against the blockchain. I suggest this as a topic for further discussions.
