Semaphore

A zero-knowledge protocol for anonymous interactions 👾

[Semaphore @SemaphoreDevs]

We’re excited to announce the release of Semaphore V4 which introduces new features and optimizations that help make building on Semaphore more seamless, cost-effective, and efficient!

Here are the updates:

Introducing: @fileverse Floppy Disk 💾

A limited-edition collectible that doubles as a 1 GB encrypted storage. Secure the Floppy Disk and experience the future of private, real-time collaboration on @gnosischain.

Get yours from the @gnosis_ app Marketplace, powered by Circles.

[Circles @aboutcircles]

Hidden powers of your Circles x Fileverse Floppy Disk

▪️ Claiming privacy is ZK secured thanks to @semaphoredevs / @PrivacyEthereum
▪️ Collaboration + storage is E2EE thanks to dDocs
▪️ Access is permissionless thanks to Gnosis Chain
▪️ Sovereignty is guaranteed thanks to @safe smart accounts

Explore new forms of private, everyday collaboration.

Soon, you'll also be able to use your Floppy to bypass the closed doors of new apps 👀

ZK Social Recovery with Semaphore 🚀
Really great work. Excited to see this!

[Fileverse @fileverse]

🥧 WHY & HOW

ZK proofs and smart contracts are two novel primitives with the potential to fundamentally improve how we live and interact on the Internet.

We need to show how, in practice, through non-financial applications, your whole digital life should not be at the mercy of one company’s infrastructure or arbitrary rules. iCloud started popularizing social recovery recently (good step forward), but it remains centralized.

🌶️We've built the privacy-enhancing, secure and decentralized alternative, building on top of the work of amazing team @PrivacyEthereum @SemaphoreDevs, and @safe smart accounts + @erc4337 account abstraction.

It's now live for both ddocs and dsheets and will be continuously improved!

[Fileverse @fileverse]

Weekly update for dDocs and dSheets🧑‍🎄💃

💛Social ZKovery: account recovery made privacy-enhancing, social & serverless

One security upgrade before we start the new year:
-Setup: add 2 trusted people to ur recovery set
-Recovery: together they can help u recover ur account

Public Announcement:

🚨 A bug was found in the BinaryMerkleRoot circuit in ZK-Kit. It allowed invalid Merkle tree leaves to generate valid ZK proofs.

This has been fixed in v2.0.0 of BinaryMerkleRoot.

@SemaphoreDevs v4, which relies on this circuit, is being updated accordingly.

All downstream projects using this ZK-Kit circuit and Semaphore v4 were notified in advance.

A new Trusted Setup Ceremony is coming soon. Stay tuned!

[Noir @NoirLang]

How do you scale private actions to millions of users?

In “Scaling Semaphore: Noir in Action,” @ViviPlasenciaC will explore how @PrivacyScaling is scaling to meet that demand, discuss the motivation behind using Noir, share benchmark results for proof generation and verification, and highlight key insights.
