Earlier this month, a conference held in Valley Forge, Pennsylvania, brought together ideas from two seemingly distant worlds. The first-ever Catholic Crypto Conference gathered over 250 Catholics - theologians, philosophers, cryptocurrency enthusiasts and professionals from the financial services industry among others - to discuss the relationship between Catholicism and cryptocurrencies. More attended online. The ethos of the conference was fraternal and inquisitive: what are the opportunities "crypto" can bring? What are the risks? And how should Catholics view blockchain technology and Web 3?
