The world’s largest cypherpunk and human rights gathering returns to Buenos Aires on November 16, bringing together over 3,000 participants to celebrate privacy, digital freedom, and open internet values.
Among the speakers are Richard Stallman, Vitalik Buterin, Roger Dingledine, and Eva Galperin — pioneers shaping the global conversation on online rights.
Unlike purely technical conferences, this event explores privacy through a broader social and ethical lens, emphasizing its vital role in sustaining democracy.
Following the success of the first Congress — which featured Chelsea Manning, Vitalik Buterin, and 50 speakers before an audience of 2,000 — this year’s edition expands its mission to strengthen cypherpunk principles, culture, and activism within the Ethereum ecosystem.
Join the movement for a free and private internet — because without privacy, there is no democracy.
