Earlier today, Coin Center hosted a briefing in Congress in conjunction with the Congressional Blockchain Caucus. We covered the basics of cryptocurrency, why it’s exciting, and went through some the policy issues the technology raises, including questions of scaling, privacy, consumer protection, and tax.
One of the things made uniquely possible by cryptocurrency is microtransactions--tiny transactions without a middleman. To visualize this concept, we used a lightning enabled candy dispenser. We were able to show the process of sending tiny amounts of bitcoin from our phones to the vending machine and watch it dispense candy in real time. The network fees were 1 satoshi per transaction.
