The quantum threat to crypto, and the privacy stack that survives it.
02 · The Second Edition
QDay Summit
On 6 June 2026, 220+ builders, researchers and investors gathered for the first QDay Summit at Network School to face a single fact: the cryptography underpinning Bitcoin, Ethereum and every major blockchain is on a countdown.
The second edition, Quantum & Privacy Day, takes place in Singapore during Token2049 and adds privacy to the discussion. Post-quantum security keeps your money safe. Privacy keeps it quiet.
Brought to you by Quantus and NEAR. Curated for founders, protocol engineers, capital allocators, and blockchain security leaders.

Because the conversation happening in that room won't happen anywhere else. This is not a conference. It's a focused conversation on the quantum threat to cryptography and the privacy stack that survives it, in one room, on the 62nd floor, during Token2049 week. If you're building, funding, or governing systems that rely on public-key cryptography, this is where you need to be.
Quantum & Privacy Day is the second edition of the QDay series, convened by Quantus and NEAR. It brings together founders, protocol engineers, capital allocators and blockchain security leaders to address post-quantum migration and the privacy stack that goes with it.
Attendance is curated and capacity is limited. Every registration is manually reviewed, so please include an active social link when you apply. Luma approved only, and no plus ones.
