Yes, Commissioner Hester Peirce is sort of the self-appointed blockchain/crypto expert, and supporter, among the Commissioners. She is certainly the most educated of them on the subject, and has been a speaker or panelist on numerous summits and conventions over the past 3 years.
I applaud her willingness to go all in on the important subject and get out there and appear at public events, something a lot of Commissioners are reluctant to do.
