human.tech Launches Clean SDK for Privacy-First Web3 Apps

human.tech has launched the Clean SDK, a toolkit enabling developers to build privacy-first Web3 applications with transparent accountability. Released alongside Aztec's version 5, the SDK provides components for integrating zero-knowledge identity verification, sanctions screening, and private transactions, without developers handling sensitive user data or building compliance infrastructure from scratch. It uses zero-knowledge proofs and programmable verification to allow apps to confirm user legitimacy and sanctions compliance while keeping identities confidential. The first application built on the SDK, Shield, a privacy bridge to Aztec, also launched. It allows users to transfer assets privately while proving a unique human is behind each transfer and that funds have passed sanctions checks, as verified by a May 2026 audit. The SDK offers three core verification techniques: Proof of Innocence (sanctions screening against 23 sources), Proof of Personhood (simpler verification via Human Passport), and Proof of Clean Hands (higher-assurance zero-knowledge government ID checks). This allows apps to authenticate users and transactions without exposing personal data. Designed for Aztec builders, the SDK lets developers add programmable privacy to decentralized apps, eliminating the need to create their own verification and ZK infrastructure. Shield demonstrates its practical use for private bridges, but the SDK aims to enable a wider ecosystem of private, accountable financial apps and services. The launch addresses growing demand for infrastructure that balances privacy and accountability. The SDK avoids traditional identity databases, storing encrypted data off-chain, screening at both entry and exit points, and including a gated disclosure mechanism for legal requests. human.tech's products, including the Clean SDK, focus on using zero-knowledge technology to enable verifiable personhood and privacy in digital systems.

Zcash price prediction – Can Ironwood upgrade keep ZEC’s 37% rally alive?

Zcash has rallied nearly 37% since its Ironwood (NU6.3) upgrade deployed to testnet in early July. This major upgrade introduces a new shielded pool and a "turnstile" mechanism to strengthen supply verification without compromising privacy. Concurrently, it marks the retirement of the legacy zcashd node, a significant architectural shift for the network. After its rally, ZEC is consolidating around $546, with buyers attempting to establish support. Immediate resistance lies near $560, with a breakout potentially targeting $600, while the $500 region acts as key support. The final testing phase precedes Ironwood's planned mainnet activation later this month.

Starknet Launches Privacy-First Bitcoin strkBTC, Targeting Institutional On-Chain Finance

Starknet introduces strkBTC, a privacy-focused version of Bitcoin designed for institutional on-chain finance. As digital assets face increased scrutiny, two major challenges emerge: the public visibility of all transactions and the looming threat of quantum computing to current cryptographic signatures. Bitcoin, representing over 56% of the crypto market, highlights these issues most clearly. strkBTC, built on Starknet’s STRK20 privacy framework, allows Bitcoin to be used privately on-chain while maintaining compliance. It operates in two modes: a public mode like standard ERC-20 tokens, and a shielded mode that hides balances and transactions from public view. This addresses the need for confidentiality in institutional finance, similar to traditional markets’ private trading venues. A third-party auditor, Financial Privacy Inc, holds view keys for regulatory access when necessary. Additionally, Starknet is positioned ahead in quantum resistance. Its STARK-based proof system relies on hash functions rather than elliptic-curve cryptography, making it less vulnerable to quantum attacks. Starknet’s native account abstraction also allows easier migration to quantum-resistant signatures without protocol-level forks. The team has outlined a roadmap to achieve end-to-end quantum security before “Q-day,” though dependencies on Ethereum’s own migration remain. While strkBTC currently uses a trusted bridge consortium, Starknet plans to transition toward more trustless, Bitcoin-native verification over time. The initiative underscores a shift in on-chain finance beyond yield—prioritizing privacy, compliance, and long-term security for institutional adoption.

Zcash's New Node Zakura Goes Live: Privacy Payments Can Reach 50,000 TPS, Aiming to Rival Visa and Mastercard

Zcash, a privacy-focused cryptocurrency, has launched a new full node software called Zakura version 1.0.0. Developed by Zcash co-founder Sean Bowe and Dev Ojha, with private ZEC donations, its goal is to enable Zcash to process over 50,000 transactions per second (TPS)—matching the scale of Visa and Mastercard—while maintaining full transaction privacy and verifiability. This addresses a key bottleneck, as Zcash currently handles only about 1 private transaction per second. Zakura is a fork of the Zcash Foundation's Zebra node. It features chain pruning and snapshots, reducing disk usage and allowing new nodes to sync in under two minutes. It also offers compatibility with the legacy `zcashd` client interface. The scalability challenge stems from the large data size of privacy proofs. Bowe's Tachyon project aims to use recursive proofs to reduce consensus-layer data needs from ~500 MB/s to ~100 MB/s. For wallet scalability, Valar Group is researching Private Information Retrieval (PIR) tech to allow wallets to fetch their data privately. Zakura supports fast block propagation and the upcoming "Ironwood" network upgrade (NU6.3), scheduled for activation around July 28th. Ironwood was created to contain a critical inflation bug discovered in the Orchard shielded pool in May 2024. The fix uses "turnstiles" to trap any counterfeit ZEC created during the vulnerability period within the shielded pool, preventing it from entering circulation and restoring supply integrity.

Crypto Watch This Week: Uniswap Fee Switch Vote Starts Today, CLARITY Act Could Face Senate Vote This Week

**Weekly Crypto Watch: Key Events & Catalysts** This week’s crypto focus is on pivotal governance votes, potential regulatory progress, and major protocol upgrades. **Uniswap** takes center stage with two crucial on-chain proposals going to vote from July 19-26. The first aims to activate protocol fees for Uniswap V2/V3 on the new Robinhood Chain and direct them to a UNI token burn mechanism. The second seeks to activate V4 fees across seven major chains, including Ethereum and Base. Robinhood Chain has already seen over $60B in Uniswap volume since its launch 18 days ago. The proposals build on last year's UNIfication plan, which transformed UNI into a fee-generating asset. On the **U.S. regulatory front**, the **CLARITY Act** could face a Senate floor vote this week. While some lawmakers are optimistic, the bill faces hurdles, needing at least 60 votes to overcome a filibuster. Prediction market Polymarket currently gives it only a 34% chance of being signed into law this year. Other notable catalysts include: * **Morpho's** fixed-rate lending protocol, **Morpho Midnight**, is set for its public launch, starting with a single market (cbBTC/USDC) on Base. * **Derive** (formerly Lyra) is preparing for its largest-ever upgrade, **V3**, which will reportedly introduce 0DTE options and a more retail-friendly UX. * **Pendle** will hold a community call on July 22 to share its roadmap, with a focus on expanding its RWA (Real World Assets) capabilities. * An undisclosed privacy-focused application for **Polymarket**, built on **Starknet**, is reportedly launching on July 20.

zcashd shuts down, Zcash enters Ironwood era: Is quantum-resistant privacy the future?

Zcash has completed its infrastructure transition by retiring the original zcashd software and fully adopting the Rust-based Zebra and Zakura node implementations. This shift, finalizing in July 2024, enhances network maintainability and prepares for the upcoming Ironwood era. Despite a previously disclosed vulnerability in the Orchard shielded pool, user confidence appears resilient. Shielded transaction volume grew 11.1% quarter-over-quarter, and the anonymity set expanded significantly, even as total shielded balances saw a moderate decline. The prompt containment of the Orchard flaw, which did not threaten total ZEC supply, demonstrated effective protocol safeguards. The incoming Ironwood upgrade aims to further strengthen long-term security through formal verification and quantum-resistant features, moving Zcash from reactive fixes to proactive, verifiable security assurances.

‘Unbounding of EF continues’ — Bitmine backs ETHSystem to advance Ethereum privacy

A new Ethereum-focused non-profit, ETHSystems, has been launched to advance privacy and confidential systems on the network, with backing from Bitmine Immersion Technologies, Sharplink, and Ethereum co-founder Joe Lubin. Bitmine Chairman Tom Lee emphasized that institutional adoption requires privacy, viewing Ethereum as a settlement layer for confidential systems. This marks the third such non-profit supported by Bitmine as the Ethereum Foundation (EF) scales down its role, a trend some analysts describe as the "unbundling" of the EF. While these new entities are staffed by former EF members, Bitmine's central financing role raises questions about decentralization. The article also discusses whether Ethereum could surpass Bitcoin in market dominance, citing growing stablecoin adoption and institutional interest as key factors, though long-term trends remain uncertain.

A Year Later, 'Lean Ethereum' Moves Forward: What Is Ethereum Aiming to Achieve?

A year after its initial proposal, "Lean Ethereum" is resurfacing as a core focus, signaling a potential fundamental shift in Ethereum's development narrative. While recent years prioritized scalability (e.g., Rollups, blobs), current discussions center on long-term sustainability and decentralization. This shift is evident on multiple fronts. Organizationally, the Ethereum Foundation (EF) is becoming "leaner and more focused," while key responsibilities like R&D (Ethlabs) and institutional outreach (Ethereum Institution) are being distributed to independent organizations. This aims to reduce systemic reliance on a single entity. Technologically, "Lean Ethereum," described by Vitalik Buterin as Ethereum's "third major iteration," outlines a 3-4 year roadmap. Its goals extend beyond raw throughput to emphasize protocol properties for a "long-term trust infrastructure." Key directions include: protocol simplification via "light verification" (using recursive STARKs instead of heavy re-execution); prioritizing quantum resistance; integrating privacy as a first-class protocol goal; and consensus-layer improvements for faster finality and reduced validator burden. Complementing this, the proposed 0x02 compounding validators feature seeks to make staking rewards more sustainable and equitable for smaller participants by allowing native reinvestment, improving capital efficiency and reducing network overhead. Together, these changes represent a move towards "subtraction": reducing dependency on centralized organizations, the cost for individuals to verify the chain, and capital inefficiencies in network participation. The aim is a more decentralized, verifiable, and resilient Ethereum capable of supporting the next decade of growth, even if the tangible benefits of these foundational shifts may take years to fully materialize.

Just Now, Musk Admits It: All Code Uploaded by SpaceXAI Deleted

Elon Musk has admitted and confirmed that SpaceXAI's coding assistant, Grok Build, was secretly uploading users' private code and data without consent, and has ordered all such data to be completely deleted. The issue was exposed by an independent security researcher who set up a "honeypot" test repository with fake API keys and passwords. Despite being instructed only to respond "OK" without accessing files, Grok Build proceeded to upload the entire repository's contents and history to a Google Cloud storage bucket. Investigations revealed that the data uploaded was 27,800 times larger than the legitimate task traffic, and the "help improve model" toggle did not stop the collection, only governing whether data was used for training. In one instance, a user's entire home directory was uploaded. The report caused immediate outrage among developers, leading to widespread key rotation and software uninstalls. Following public pressure, SpaceXAI introduced a `/privacy` command for data deletion and, ultimately, Musk pledged to delete all previously uploaded user data with "zero anything whatsoever will remain." The incident has severely damaged trust in AI coding agents, highlighting the inherent risk of granting such tools high-level system access. While the data may be erased, the fundamental concern over privacy and security remains unresolved for developers.
