    ‘Deathmatch’ panel on private versus public blockchain heats up at South by Southwest

    Arguments over what it means to be truly decentralized

    A panel over the future of walled-garden blockchain nodes versus so-called “permissionless” blockchain stopped short of getting personal, but was still more contentiously vocal than most talks at South by Southwest in Austin, Texas. It included IBM OpenTech’s Christopher Ferris, a computer scientist and author of the company’s Blockchain Pulse blog; St. Mary’s University School of Law professor Angela Walch, who is also a research fellow at the Centre for Blockchain Technologies at University College London; and Jimmy Song, a venture partner for Blockchain Capital, Bitcoin Core developer, and author.
