@Rarimo_protocol has launched its much anticipated zkRollup, featuring the world’s first public, decentralized identity registry powered by EIP-7812: https://x.com/Rarimo_protocol/status/1899472530588492272…
This enables users to create private, permissionless IDs without government or corporate control, enabling use cases like anonymous voting. The system aggregates various proofs - from passports to biometrics - and scales on @ethereum.
Rarimo were also a major sponsor of the recent @Zk_Hub_Global, where Co-founder @LashaAntadze gave a talk titled 'Client-side ZKAI - Biometric proofs' before moderating a panel on how AI can benefit from ZK, alongside @MinaProtocol Co-founder @evanashapiro and other prominent figures.
@PrivadoID has launched @billions_ntwk, a decentralized network enabling both humans and AI to verify identity using only a passport and phone, without requiring biometrics or special hardware: https://privado.id/blog/privado-id-introduces-billions-the-first-global-human-ai-network…
Built on privacy-focused ZK technology, Billions gives users full control over personal data. The network aims to tackle online trust issues like AI deepfakes and fraud, offering a scalable, accessible alternative for global proof of personhood.
In other news, Privado ID Co-founder @provenauthority led a highly anticipated panel discussion focused on the question of whether privacy is essential for crypto mass adoption, joined by key figures from @AleoHQ, @HorizenLabs, @zkPass, and @aztecnetwork.
@MinaFoundation’s @yunusguerlek took part in the Privacy x Verifiability conference at @EPFL_en on March 7, focusing on data privacy and verification. The following day, a 36-hour blockchain privacy hackathon was held by the Blockchain Student Association with support from @MinaProtocol, @hyle_org and @hedera, where developers worked on privacy and verifiability solutions, competing for a $15,000 prize pool: https://x.com/AstrominaOrg/status/1898770007120846981
@Aleph__Zero shared an article explaining why shielding is essential for blockchain users. Shielding makes assets private using Aleph Zero’s zkOS framework, protecting identities and transactions from public view. Through Common, users can manage and trade assets securely without complex steps. Aleph Zero also plans to extend shielding across multiple chains, aiming to bring privacy to broader web3 ecosystems through its growing shielder network: https://alephzero.org/blog/why-crypto-users-need-shielding/…
Additionally, the project announced the introduction of relayers to its network, enabling AZERO holders to support private transactions and earn rewards. Relayers require less hardware than validators, enhance zkOS privacy, and offer dual incentives for both relayers and nominators, advancing decentralization and privacy:https://x.com/Aleph__Zero/status/1891874619168006336…
@matthewniemerg, Co-founder of Aleph Zero, shared his thoughts on why businesses won't adopt blockchains without built-in privacy. He argues that radical transparency exposes sensitive data, threatening competitiveness and trust. To succeed, blockchains must balance verification with confidentiality, using technologies like ZKPs: https://cryptoslate.com/business-cannot-thrive-on-radically-transparent-blockchains/…
Finally, @Common__App Extension V1.04 is now live in the Chrome Store. It introduces an activity history feature, letting users track both private and public actions while maintaining privacy. The update installs automatically, so users don’t need to do anything. More details, including the full changelog, are available on the official site: https://x.com/Common__App/status/1898019945646035207
@horizenglobal announced it is joining @base as one of its first appchains, focusing on scalable, privacy-first applications.
