Once described by PGP creator Phil Zimmerman as “the Mister Rogers of cryptography,” Hal Finney (1956) was known for his relentlessly uplifting spirit. He carried a positive perspective on life with him even when amyotrophic lateral sclerosis (ALS) paralyzed his entire body, until the Bitcoin pioneer ultimately passed away from the disease on August 28, 2014.

Finney, too, liked to operate on the cutting-edge of technology. When the internet became publicly available for the first time in the early 1990s, he immediately began to explore the World Wide Web and other corners of the brand new information superhighway, and quickly recognized the revolutionary potential embedded in the nascent network.

As communication went digital, anyone’s conversations were in peril of being monitored. The Net could represent an encroachment on everyone’s privacy and, therefore, become a possible threat to human liberty.

This was true for regular communication, and Finny realized it was equally true for financial…
