Criminal cyber attacks on health care information repositories have increased 125 percent since 2010. With the announcement of the Excellus breach last week, the total number of big-headline medical information compromises reported in 2015 had crossed the mind-blowing demarcation line of 100 million files.
A blockchain is public ledger of transactions that is distributed among all participants in a market or system. Each transaction that happens within a market or system must be verified by a strong majority of participants.

What differentiates the ALM hack is that it has moral ramifications.
