--- layout: post title: "Zcon0 Recap" excerpt: "Talks and resources from our first Zcash conference." categories: blog tags: [Zcon] image: feature: date: 2018-07-12 author: sonya --- Zcon0 was our first annual conference, and it went incredibly well. We spent June 26 – 28 in beautiful Montréal, where we were blessed with sunshine and warm weather. It was wonderful to have so many members of the Zcash community together in one place, including developers from different projects such as Ethereum, Monero, ZenCash, Siacoin, and the Coda Protocol. We were especially thrilled to announce our inaugural Privacy Guardian Award, which we bestowed on pseudonymous community member [mineZcash](https://www.zcashcommunity.com/). This person exemplifies the Foundation’s values and their presence is a boon to the community. The Foundation extends its thanks to everyone who helped make the event happen: [Paige](https://twitter.com/ioptio) and [Ryan](https://twitter.com/AdjyLeak) from the Zcash Company, the many speakers and workshop leaders, the [in•clued](https://inclued.com/) team, and staff from the [venue](https://www.fairmont.com/queen-elizabeth-montreal/). Of course, heaps of credit go to our own Operations Director [Antonie Hodge](https://twitter.com/antoniehodge), who was the primary organizer and made everything run smoothly. > "Excited to be at #zcon0 and great to see the Zcash community's strong and consistent commitment to security and privacy." — [Vitalik Buterin](https://twitter.com/VitalikButerin/status/1011700102690271232) # Presentations All the talks are available to watch in a [playlist on YouTube](https://www.youtube.com/playlist?list=PL40dyJ0UYTLK507afWUMgzUYeh-i4qQWS).

Additional resources that speakers and workshop leaders shared: * [Justin Smith’s scorecard for mobile wallets](https://jsmith.website/scorecard.pdf) * [Simon Liu’s recap of the cryptocurrency mining workshop](https://forum.z.cash/t/what-happened-at-the-zcon0-mining-workshop-and-more/30062) * [Daira Hopwood’s circuit optimization handout](https://docs.google.com/document/d/1aZ1GUAJOBFuqD4GOo9HqAH8w4xJo7HM4Bjte5-wkdnU/edit) # Outside Coverage The Zero Knowledge podcast [dedicated an episode](http://www.zeroknowledge.fm/32) to covering Zcon0, including interviews with attendees and speakers. CoinDesk reporter Rachel O’Leary covered the conference in a series of articles: * [“Zeroing In: Zcash Sets 2-Year Course for Better Crypto Privacy”](https://www.coindesk.com/zeroing-zcash-sets-2-year-course-better-crypto-privacy/) * [“Zcash Votes Against ASIC Resistance In Boon for Big Miners”](https://www.coindesk.com/zcash-governance-panel-shoots-research-asic-resistance/) * [“What Does Crypto Care if Zooko Is a Millionaire?”](https://www.coindesk.com/zooko-wilcox-ohearn-zcash-millionaire/) Additionally, Alejandro Machado [recapped the governance keynote](https://twitter.com/alegw/status/1013954471460851714) in a Twitter thread, Lucas Vogelsang blogged about [“The State of ZApps,”](https://medium.com/@lucasvo/the-state-of-zapps-first-edition-zcon0-conference-notes-51b53ac52a88) and Alexis Gauba asserted that [“Cypherpunk is Not Dead”](https://medium.com/thunderofficial/team-ramblings-cypherpunk-is-not-dead-a25501ddbee1) (we agree). # Feedback In a post-Zcon0 workshop, we collected suggestions of what we could improve next time: * Allow speaker Q&A instead of pushing all questions to the workshops * Give workshop leaders more clarity about the format in advance * Announce and explain the Chatham House Rule to all attendees * Let the workshop leaders project a computer screen or even slides * Tinker with the workshop summary format so that the knowledge needed for each one builds on the previous section * Break workshops into separate rooms * Have a clear Schelling point for social discussion and after-event planning * Consider having lightning talks * Account for displaying slides in the livestream * Print the nametags on both sides * Give journalists a clearly marked badge * Facilitate student attendees to connect with each other * Make sure beginners feel welcome and accommodated That’s a wrap. Thank you again to everyone who participated in Zcon0! Here’s to another fantastic conference next year.
