The Present and Future of Privacy on Tezos
Want to learn more about the exciting developments on Tezos that are protecting your privacy?
This Session, hosted in collaboration with ZKProof, featured a presentation by Marco Stronati and Marc Beunardeau from Nomadic Labs. They provided us with a very detailed and informative look into the technical aspects of Sapling, demonstrating how the privacy-preserving protocol uses a process called shielded transactions to allow users anonymity when conducting transactions on the blockchain.
Stream this Session to learn more about the emerging privacy infrastructure on Tezos and what this means for the future.

TQ Tezos’s Co-founder Jacob Arluck had a moderated discussion with Marco Stronati and Marc Beunardeau from Nomadic Labs.
Marco presents the work of the privacy team at Nomadic Labs.
7:50
Marco talks about sapling and the use of sapling on Tezos.
15:40
Marc presents the current privacy plan at Nomadic Labs, like enhancing sapling.
24:30
Marc explains why we need a universal trusted setup ZK scheme.
25:40
Deep dive in PLONK.

Audience Q&A Session:
Moderator Jacob asks Marco and Marc questions from community members.
Q: Are there any solutions to get access controls with shielded transactions?
35:15
Q: How far away this solution is?
36:20
Q: How does the idea of a multi-asset shielded pool at Cryptium Labs play into your effort?
39:50
Q: How far are we from the first sapling?
41:20
Q: Can we have some sort of accumulator schemes for ACL (Access Control List)?
42:08
Q: Is there any overlap between the sapling implementation in Tezos and a future protocol upgrade that leverages ZKProofs for block compression as seen in Coda and Mina?
43:50
Q: Is there any chance that sapling will eventually be implemented in a way to automatically make all XTZ transactions private by default?
45:12
Q: Will ZK proofs be compatible with voting during proposals? So you could be a private baker and vote but not have it publically visible?
46:42
Q: In terms of scalability, how many sapling transfers of tez can you make per block?
50:22
Q: Not ZK related, but do you have any comments on the status with Tenderbake? How is it progressing?
50:57
Q: What do you think will be the most common pitfall that will lead to unwilling deanonymization?
53:50

This Session is hosted in collaboration with ZKProof. The ZKProof standardization effort is excited to partner with TQuorum to bring this session on how Sapling, one of the most widely adopted ZK protocols, has been integrated into the Tezos smart contract functionality. We appreciate the continued support of the standardization effort as a sponsor of our 3rd ZKProof Annual Workshop. Currently, ZKProof hosts a series of working groups dedicated to push standards forward in order to facilitate adoption across different topics and would love for you to join the effort!

New Sessions will take place every Wednesday—sign up for our newsletter updates so you never miss one.
