And, of course, at other times a generic Paypal-like institution is indeed the best approach. In the case of Bitcoin 1.5, however, we are dealing with a world of factum law and decentralized technology, so we can be much more clever with how we combine two approaches - arguably, in fact, it is possible to get the best of both worlds. Some people, faced with the large number of exchanges getting hacked, see technologies like paper wallets, offline laptops and brainwallets with prepended usernames and twenty-character passwords as the solution; essentially, a return to the tried-and-tested best practices for storing gold in the twentieth century, plus a bit more complex technical magic built in.

In reality, however, Bitcoin users and services are losing substantial sums of bitcoin every week, and without chargeback-like consumer protections there are several high-profile stories of companies particularly in the Bitcoin mining industry taking users' bitcoins and only delivering a low-quality product several months too late, if at all. What CryptoCorp is doing is taking this basic idea, and applying two major improvements. Every time the CryptoCorp server receives a transaction to co-sign, it will run the transaction through a complex machine-learning fraud-detection model taking into account the amount, the frequency and amount of prior transactions and the identity of the recipient, and will assign the transaction a risk score.

Since there are far more non-criminals than criminals, one can easily argue that the frictionless nature of Bitcoin can offer benefits to society at large that outweighs this downside. With Armory you are in complete control of the creation and storage of all Bitcoin private keys. Consumer wallets will all be 2-of-3 multisig, sharing the keys between either a low-security local-storage key, a high-security key in a safety deposit box and a central provider, or two central providers and a low-security key.
