@cloak_xyz safe to say Cloak is the “Zcash (as network, not token) on Solana”? how different is the design? can you make a comparison?

@mgf_sol Similar goal (privacy), different design. Cloak is built for Solana execution using Shield Pool + Groth16 + viewing keys (selective disclosure). Docs: architecture/proofs sections in our technical documentation.

Privacy without accountability fails institutions. Accountability without privacy fails operators.

@mgf_sol Selective disclosure is done with viewing keys: private by default, but the owner can reveal specific transaction data to an authorized party. Basis is Groth16 proofs over Shield Pool commitments/nullifiers.

@mgf_sol Shield Pool + Groth16 proofs. Transactions are private by default, with selective disclosure when needed.

I created a Solana AI auditing system that costs 99% less than a formal audit. It is still very much in beta, but we're using this system at @exo_tech_ to promote safer Solana smart contract development. Sign up and give it a try! ai-audits.exotechnologies.xyz

@HardhatChad @toly what if everything is private and we prove X amount is playing without revealing who is playing? 🤔

@toly Looking into this. But in general, a public board leads to more play than a blind board

The Solana Hacker Hotel in Argentina marked a new chapter for @solana builders in LATAM. 10 days, 52 people from 6 countries, 8 workshops, 3 side events, 2 mini hackathons — all with one mission: accelerating the Solana ecosystem across Latin America. Huge thanks to @raikucom, @solflare, and @triton_one for supporting local initiatives in our region. It's an honor to have such strong and aligned partners by our side. Next stops: Solana Economic Zone and Breakpoint. Never stop building. The Brazilian storm will baldly hit Abu Dhabi. 🇧🇷⛈️🇧🇷

If you're a privacy founder - let's talk. Writing $500k-1.5m pre seed checks now
vitalik.eth@VitalikButerin

Encrypted messaging, like @signalapp, is critical for preserving our digital privacy. Two important next steps for the space are (i) permissionless account creation and (ii) metadata privacy. @session_app and @SimpleXChat are two messaging apps pushing these directions forward. For this reason I've donated 128 ETH to each. Addresses available on their websites if you wish to follow on: getsession.org simplex.chat But also, actually download and use them! Neither of the two are perfect pieces of software, they have a way to go to get to truly optimal user experience and security. Strong metadata privacy requires decentralization, decentralization is hard, users expecting multi-device support makes everything harder. Sybil / DoS resistance, both in the message routing network and on the user side (without forcing phone number dependence) adds further difficulty. These problems need more eyes on them. I wish all teams working on these important problems best of luck.

Cloak now supports private SPL transfers and swaps. A new layer of privacy on Solana - invisible movement, verifiable settlement. We’re building the privacy rail so users and builders can operate without exposing their entire state to the world. More to come.
