Here we report on the progress of the leading builders in the Privacy ecosystem, documenting recent significant releases, technical breakthroughs and general updates
Articles
@AleoHQ wrote an article in which it explains how its view key system addresses the longstanding tension between privacy and regulatory compliance in crypto. Instead of exposing user data by default, Aleo accounts feature cryptographic “windows” called view keys - protocol-native tools for selective disclosure.
With account and transaction-level view keys, Aleo enables secure, auditable disclosure on demand, preserving both privacy and compliance without centralized data storage: https://aleo.org/post/aleo-view-key-compliance/
Launches
@worldcoin has launched AMPC, a new open-source system using anonymized multi-party computation to protect iris codes in biometric verification. It enhances privacy by avoiding plaintext data and using cryptography at every stage. With NVIDIA H100 GPUs, AMPC supports ~50 million pairwise comparisons per second.
Independent partners now run the system, ensuring decentralization and transparency, while ongoing development focuses on scaling, efficiency, and maintaining user privacy at a global level: https://world.org/blog/engineering/introducing-ampc-another-leap-privacy-performance-world-id…
In addition, World ID offers private age verification without exposing personal data. Users tap their passport’s NFC chip in the World App, the date-of-birth field is encrypted and stored solely on the device.
When a site requests confirmation, a ZKP returns only “yes” or “no” for the required age. No documents, birth dates, biometrics, or cloud storage are involved, and integration via API is straightforward: https://world.org/blog/policy/a-new-privacy-preserving-age-assurance-technology-for-the-digital-age…
Partnerships
World is teaming up with Rappi to offer at-home World ID verifications, starting in Belgrano and Palermo, Argentina. Users can schedule an Orb visit through the Rappi app, letting trained couriers handle the process directly at their location. The service aims to make human verification more accessible as digital identity grows in importance:

Adoption
World is expanding access to its privacy-focused human verification system in response to rising global concerns about AI impersonation and online trust. The World ID protocol allows users to prove they are human without sharing personal data, offering an anonymous safeguard in digital interactions:
Taiwan:
Residents can now verify their World ID at a World Space in Taipei using an Orb device. With high internet usage and early AI adoption, Taiwan fits naturally into World’s network. A recent survey shows 88% of people worry about distinguishing bots from humans. Verification is private, stored only on users’ devices: https://world.org/blog/announcements/world-launches-in-taiwan…
United Kingdom:
The service launched during London Tech Week, with verification points open in London and expansion planned for cities like Manchester and Glasgow. Public concern is growing: 75% say it’s essential to prove humanness online. World ID offers anonymous, secure identity proof without storing personal or biometric information: https://world.org/blog/announcements/world-launches-in-the-uk
Launches
@zkemail has launched its Registry platform, allowing users to create ZKPs without needing cryptography skills. It enables verification of select email elements - like sender or content - while keeping identities private.
Proofs are generated locally and can be shared with parties such as journalists or officials. Use cases include whistleblowing, event confirmation, and discreet financial verification: https://x.com/zkemail/status/1930302609828770135…
Tech
ZK Email has introduced a new account recovery demo using Passkeys and EIP-7702. Users can upgrade their burner wallets to Safe Smart Wallets, where the Passkey becomes the wallet owner. An email can be added as a guardian, enabling recovery if needed. This aims to simplify crypto wallet use and improve onboarding for mainstream users: https://x.com/zkemail/status/1934641936213889512…
Partnerships
ZK Email partnered with @OpenZeppelin to integrate Email Signers into Account Signers. This allows developers to use email-based authentication in smart contracts while leveraging OpenZeppelin’s secure, upgradeable framework.
The feature aims to simplify Web3 access for non-crypto users by enabling easier, secure interactions with wallets and blockchain transactions through familiar email tools:

Tech
@Rarimo_protocol has introduced UltraGroth - a modification of Groth16 that enables the use of lookup tables to optimize non-linear activations in Bionetta circuits. Instead of checking each bit individually, inputs are split into chunks and verified against a table.
This reduces the number of constraints from 977,592 to 127,360. Security is ensured via a deterministic rand value derived from a hash of an intermediate commitment: https://mirror.xyz/0x90699B5A52BccbdFe73d5c9F3d039a33fb2D1AF6/T4lHiBlo7VoYp-5SEuitQnY7_ullpwkZbanOOwjeZI4…
Optimization
The team shared an article explaining how embedding weights as constants in R1CS circuits can make linear operations constraint-free, significantly improving proving efficiency. The piece compares R1CS and Plonk, showing that R1CS benefits more from this optimization.
Bionetta, their client-side proving system, leverages this technique to reduce proving time, enabling large models like zkLiveness to run with around 100K constraints efficiently: https://mirror.xyz/0x90699B5A52BccbdFe73d5c9F3d039a33fb2D1AF6/p4SxosKTbrdxhociK-vNCk_K9EMpa-hpke-YKtpZ49A
Update
@nymproject released NymVPN v2025.10, focusing on improved connection stability and app performance. The update fixes the “One Hour Bug,” improves bandwidth top-ups, and resolves issues with startup and background disconnects across platforms.
Android users see better stability, and desktop apps get auto-updates and connectivity fixes. NYM plans to add in-app payments, PayPal and crypto support, DNS customization, and stronger censorship resistance in upcoming updates: https://nym.com/blog/nymvpn-v2025.10…
Articles
Nym has published an article covering how AI tools like ChatGPT are widely used at work, often through personal accounts, raising serious privacy concerns. Their survey shows employees regularly input sensitive data - from customer and company information to personal health and financial details. Yet few understand metadata risks.
While AI boosts productivity, respondents want encryption, data deletion, and tools like NymVPN to protect their privacy and restore control: https://nym.com/blog/convenience-vs-caution-AI
Partnerships
@zkPass announced two new collaborations aimed at advancing private and verifiable identity infrastructure across Web3:
• @TakerProtocol: Partnered to integrate zkPass’ privacy-preserving data oracle into BTC yield strategies, enabling sybil-resistant reputation signals without exposing user data - a key step toward real-world adoption of verifiable BTC earnings: https://x.com/zkPass/status/1928486972802166792…
• @Polyflow_PayFi: Teamed up to enable privacy-first identity for PayFi applications. By leveraging zkPass’ zkTLS protocol, the partnership allows sensitive Web2 credentials (like credit scores) to be verified onchain - without exposing the underlying data - for use in payments, credit, and healthcare: https://x.com/zkPass/status/1933366845253493227
