I've been meaning to link to this one for a few days. Antonopoulos appeared before the Canadian Senate on October 8th. CoinDesk:
A decentralized system, Antonopoulos suggested, is actually more secure. Unlike ‘pull system’ credit card transactions where customers trusted merchants with full access to their accounts, bitcoin’s ‘push system’ left control with users.
Bitcoin transactions could be sent in the clear and unencrypted over open networks without fear of compromise, which allowed the infrastructure to be open to any participant or software application without vetting, authorization or identification.
Contrary to popular belief, he added, bitcoin is not unregulated. It is “regulated by mathematical algorithm” and puts core security functions into its users’ hands.
