Dear sir, the entire NSA staff are currently plugging away on that pesky P=NP problem, including datacenter janitors.

I have suspected for awhile now that the bitcoin blockchain is actually an attempt to break SHA-256. Bitcoin is built around incentives, and it has created an incentive for people all over the world to basically brute force this algorithm and maintain a recursive set of low entropy outputs.

Which would make the btc blockchain an incredibly expensive and valuable data set, for someone armed with the right mathematical theory.

How could you break it without destroying its value?

Why would the NSA care about destroying Bitcoin's value?

Part of Security is knowing your adversaries power. I think you might be on the right track. You can’t put a price on the security of an algorithm. However, Satoshi gave us a very good metric for calculating it.
