The differences between the two attendees were further put on display by way of comments published after the appearance before the U.S. senators. Following the event, Van Valkenburgh said in a statement that he appreciated "the opportunity to present the committee with real-world examples of the value public blockchain networks can bring to society, and to respond to some of the criticisms that have been leveled against them for years." In contrast, Roubini took aim at the many social media critics who responded disdainfully to his remarks as the hearing went on. Roubini tweeted:

Roubini will testify before the U.S. Senate Committee on Banking, Housing and Urban Affairs alongside Coin Center director of research Peter Van Valkenburgh in a hearing entitled "Exploring the Cryptocurrency and Blockchain Ecosystem." Announced last week, the hearing marks the latest move by members of the U.S. Congress to better understand the emerging technology and asset class.
