Zcon is an annual conference that the Zcash Foundation organizes, with a focus on Zcash and privacy-preserving technologies.
This year’s theme is “The Future Has Not Been Written.” This year we strive for all attendees to not only learn about updates in the ecosystem but we hope to inspire positive change within the cryptography world.
Zcon4 will be held in-person, at the Hilton Diagonal Mar Barcelona in Spain from 8:00 CEST Sunday, July 30-17:00 CEST Tuesday, August 1. We recommend arriving on Saturday, July 29th and planning to stay the night of Tuesday, August 1st.
Zcon4 will also have a virtual component, so that community members who are unable to attend in-person, can still view and participate in the event. Virtual registration is now open.
You can register for Zcon4 and ZK Week events (Crypto Lounge Experience & ZK Proof 5.5) here.
*The Zcash Foundation reserves the right to refuse attendance to anyone who has violated the Code of Conduct at any time in any virtual or in-person space and anyone that the Foundation deems may detract from the mission of the conference. In this case, ZF will refund the conference fee and communicate with the registered person accordingly.
We are no longer accepting speaker proposals.
The deadline to apply for a scholarship has passed and we are no longer accepting applications.
Privacy-preserving technology requires developers and community members with both talent and passion. The Zcash Foundation supports future privacy leaders who are working towards a career in the financial privacy ecosystem and community members who need financial support. The Zcon4 scholarship we offer supports travel (an economy-grade flight up to $1,500 USD), lodging expenses during the conference, and we will waive the conference ticket fee for those whose contributions are vital to the financial privacy ecosystem. Amounts vary based on geographic location and need; we evaluate on a case-by-case basis.
Yes! Once you complete your registration, you will receive an email with a link to book using the Zcon4 discount.
Space is limited so we recommend booking ASAP.
Attendees are responsible for booking flights and accommodation at the Hilton Diagonal Mar Barcelona (discounted group rates are available; breakfast is included with your hotel reservation).
We will start announcing speakers in early summer. The schedule from last year’s Zcon can give you an idea of the types of presentation subjects and speakers to expect.
Some things to consider when packing to attend Zcon4:
In order to fully control the environment for Zcon4 we decided to secure all of the meeting and breakout rooms on the first floor so only attendees wearing the Zcon4 name badge will be able to enter the meeting space. Additionally, the foyer outside the meeting space opens up into an outdoors courtyard where attendees can mingle and take breaks; we plan to leave the doors open, when possible, to increase airflow.
There is no smoking in the meeting space area or hotel (only outside in designated areas).
Barcelona is a vibrant city full of life, which is exactly the type of energy we want to elicit at Zcon4.
Much of the communication for both in-person and virtual attendees will happen virtually on the Whova app so everyone in the community can participate. Anyone can view the sessions that are livestreamed on the Zcash Foundation’s YouTube channel without registering.
To participate in discussion with other participants and to ask speakers questions, you must register with a name and email address and agree to our Code of Conduct policy – virtual attendee registration is now open. The name you enter will be your public username when you participate in the chat during the conference. If you would like to use a pseudonym, enter it as your first name with “.” as your last name. There is no fee for attending virtually.
The Whova app is your go-to resource for Zcon4. You can add sessions to your calendar, participate in discussions with other attendees, ask speakers questions, watch live streams of each session, and have access to other important info for ZK week. Check out this Whova guide for the web and mobile app.
Thank you for asking. All communication and interactions, both in-person and virtual, are subject to the same Code of Conduct as the Zcash forum
