NoConsensus.wtf @ SBC'25

[system]

​NoConsensus.wtf brings together researchers and engineers to discuss censorship-resistance, scalability, and anonymity in blockchain p2p layers. At this event we’ll explore various Ethereum P2P bottlenecks, R&D in anonymous broadcast (e.g. ZipNet , ADC Net), and Information Flow Control for P2P Confidential Containers.

​No product or marketing pitches, presentations are meant to calibrate discussions. Expect to exchange research insights and get ready to whiteboard.
