Aztec v5 brings private smart contracts to Ethereum in alpha launch

Aztec v5 brings private smart contracts to Ethereum in alpha launch

Aztec has launched the alpha version of its v5 execution layer, introducing a programmable privacy framework that allows Ethereum applications to process both public and private state within the same layer-2 environment.

Summary

  • Aztec has released the alpha version of its v5 execution layer, bringing programmable privacy to Ethereum through zero knowledge powered smart contracts.
  • The new architecture processes private computations on user devices while verifying transactions on chain without exposing sensitive data.
  • Aztec said the execution layer supports confidential decentralized applications with features designed to reduce front running and MEV risks.

Aztec Labs announced the alpha release of its v5 execution layer, describing it as a step toward making privacy-native smart contracts practical on Ethereum. 

The new architecture allows developers to build decentralized applications that combine confidential user data with public blockchain state while relying on zero-knowledge proofs to verify transactions without exposing sensitive information.

Unlike Ethereum’s base layer, where every validator processes and stores transaction inputs, outputs, and execution data to reach consensus, Aztec’s execution layer moves private computation to the user’s device. Instead of revealing transaction details to the network, the system generates cryptographic proofs locally before submitting them for verification on-chain, reducing the amount of visible transaction data while preserving Ethereum’s security guarantees.

Client-side execution changes how private transactions are processed

At the center of the release is a client-side zero-knowledge execution engine integrated with Noir, Aztec’s domain-specific programming language for private smart contracts. Rather than executing confidential transactions across every network node like the Ethereum Virtual Machine, the system performs private computations on user hardware before generating recursive Succinct Non-Interactive Arguments of Knowledge, or SNARKs.

Those proofs allow the network to verify that state changes are valid without exposing plaintext inputs, transaction values, or account identities. According to Aztec Labs, the model cuts unnecessary data disclosure while maintaining mathematical guarantees that transactions have been executed correctly.

The architecture also introduces a hybrid state model designed to overcome one of the biggest engineering challenges facing privacy-focused blockchains. Purely private execution environments often struggle when multiple users attempt to update the same public state at the same time, creating state contention that limits interaction with shared decentralized finance infrastructure.

To address that limitation, Aztec separates private and public state management. Private assets are stored in UTXO-like note trees, while public data is maintained through key-value trees. During execution, private functions can generate deferred public function calls that are processed later within the same transaction lifecycle, allowing confidential and public operations to work together without sacrificing deterministic execution or creating race conditions.

The execution model is intended to support applications that require confidential computation while still interacting with Ethereum’s public ecosystem, including shared liquidity pools and other decentralized finance protocols.

Privacy model targets decentralized finance and enterprise applications

Beyond transaction privacy, the execution layer introduces features that could reduce several long-standing issues in blockchain execution.

According to Aztec Labs, transaction details remain hidden before state commitment, making it significantly harder for external observers to reorder pending transactions or exploit visible transaction data through Maximal Extractable Value strategies.

The architecture also provides building blocks for applications such as confidential order matching, private liquidity provisioning, and selective compliance systems that disclose only required information through viewing keys instead of exposing complete user records.

Those capabilities build on Aztec’s long-standing focus on programmable privacy rather than simple anonymous token transfers.

Speaking to crypto.news in April 2025, Aztec Labs co-founder and CEO Zac Williamson said blockchain privacy should go beyond hiding wallet addresses.

He described user privacy, confidential transaction data, and private smart contract execution as the three pillars needed for practical on-chain privacy, calling them “the holy grail of blockchain privacy.” 

Williamson also argued that privacy should not be treated as a separate segment of the industry, saying, “all crypto will be private” as programmable privacy becomes part of mainstream blockchain applications.

Discussing compliance, Williamson said privacy preserving systems should rely on selective disclosure instead of complete anonymity. He pointed to ZKPassport as an example, explaining that users can tap an NFC enabled passport to generate a zero knowledge proof and choose “what information you want to disclose,” whether it is nationality, age, or other identity attributes. 

He said the technology is “permissionless, it’s privacy preserving, and it ensures strong compliance,” adding that such systems are “a lot more powerful” than existing privacy solutions because they combine privacy with programmable compliance.

That vision expanded further in May 2026 when Aztec Labs acquired ZKPassport while committing to keep the passport verification platform open source. The acquisition brought the privacy-focused identity infrastructure directly into Aztec’s ecosystem, allowing developers to combine programmable privacy with zero-knowledge identity verification across Ethereum-compatible networks.

The technology had already been tested on Aztec’s network to help reduce Sybil attacks by allowing participants to prove they were unique individuals without revealing their identities. It was also used during the AZTEC token sale to perform sanctions screening while keeping participant information private.

Alpha release follows security incidents involving legacy products

The execution layer arrives shortly after Aztec Labs dealt with security issues involving products that had already been retired.

Earlier this month, Aztec Labs disclosed that it was investigating a potential exploit involving a deprecated payments product launched in 2021 after roughly $2 million was transferred from an immutable smart contract. The company said the affected system had been discontinued in 2022 and operated without administrator keys, preventing the team from pausing or upgrading the contract.

Separately, another deprecated product, Aztec Connect, lost approximately $2.1 million after attackers exploited an old immutable RollupProcessorV3 contract. Aztec Labs said the incidents were unrelated to the active Aztec network.

The Aztec Foundation also stated that neither exploit had any connection to the current network or the AZTEC ERC-20 token, emphasizing that the affected contracts belonged to legacy infrastructure that had remained live on Ethereum after the products were sunset.

Kazakhstan Signs Network School Deal as Malaysia Revokes License

Published

on

Crypto Breaking News

Balaji Srinivasan’s Network School is looking to expand into Kazakhstan after regulators moved against its Malaysia operations, according to a memorandum of understanding announced by Kazakhstan’s Ministry of Digital Development, Innovation and Aerospace Industry. The deal, signed with minister Zhaslan Madiyev, aims to establish what the ministry describes as the first Network School campus in the country.

The Kazakhstan announcement comes as Network School’s Forest City-area presence faces escalating regulatory pressure. Malaysia’s local authorities revoked the business license of the operator, NSO Malaysia Sdn Bhd, prompting the Malaysia Digital Economy Corporation (MDEC) to begin steps to remove the company’s Malaysia Digital status. The situation raises the question of how easily Network School can restart and maintain immigration- and incentives-related arrangements across borders.

Key takeaways

  • Kazakhstan’s ministry says it has signed an MoU with Balaji Srinivasan to create the first Network School campus in the country.
  • Malaysia’s Iskandar Puteri City Council revoked NSO Malaysia Sdn Bhd’s business license over alleged licensing and premises-use breaches.
  • MDEC says it is taking immediate steps to revoke NSO Malaysia’s Malaysia Digital status, which comes with benefits such as tax incentives and employment flexibility.
  • Local officials in Johor have urged federal authorities to keep investigating whether Network School violated immigration laws.
  • Srinivasan has framed the developments as consistent with the “network state” concept, while also saying Malaysia issues are being addressed through a remedial process.

Kazakhstan MoU opens a new front for Network School

In a statement from Kazakhstan’s Ministry of Digital Development, Innovation and Aerospace Industry, the government said an MoU was signed with Zhaslan Madiyev and Network School founder Balaji Srinivasan to establish a campus in Kazakhstan. While the document signals a strategic expansion, details of implementation—such as timeline, campus location, and regulatory steps—were not included in the provided reporting.

Network School’s Kazakhstan pivot matters for prospective residents and investors because campus operations are closely tied to host-country regulatory conditions, especially around visas, employment rules, and corporate status benefits. Srinivasan has previously described Network School as a community built around attracting globally distributed talent and capital, and the Kazakhstan proposal positions the group to potentially preserve momentum rather than waiting for a resolution in Malaysia.

Kazakhstan has also been positioning itself as a technology hub, including plans connected to a “crypto city” in Alatau, as referenced in the source material. Against that backdrop, Network School’s presence could be marketed as part of a broader attempt to draw innovation-driven communities and companies to the region.

Malaysia: revoked license and a threat to Malaysia Digital status

Malaysia’s regulatory actions began after the Iskandar Puteri City Council (MBIP) revoked the business license of NSO Malaysia Sdn Bhd, the entity operating the Network School’s Johor-area campus. MBIP cited alleged breaches of licensing conditions and requirements related to how premises were used, according to a report linked in the source material from mediadigitaljohor.gov.my.

Following the license revocation, MDEC announced it was taking immediate steps to revoke NSO Malaysia’s Malaysia Digital status. The Malaysia Digital program recognizes qualified technology and digital companies and is described in the source material as offering incentives such as tax advantages, ownership flexibility, and permission to employ both local and foreign workers—benefits that can be critical for international communities that rely on a steady inflow of talent.

MDEC’s stated rationale is that Malaysia Digital status requires companies to comply with local and federal laws. Removing that status could complicate Network School’s ability to operate smoothly if the campus depends on the program’s employment and incentives framework.

Johor officials push for immigration-law scrutiny

The stakes extend beyond corporate licensing. The source material says Johor Chief Minister Onn Hafiz Ghazi urged Malaysia’s federal authorities to continue investigating whether Network School violated immigration laws. He characterized Johor as a “strategic entry point” because the state borders Singapore and therefore argued that any weaknesses or abuse of the immigration system should be addressed promptly and firmly.

Advertisement

That emphasis highlights a common tension for border-adjacent technology hubs: even when a concept has strong global appeal, enforcement actions tied to immigration compliance can quickly affect day-to-day operations, staffing, and residency arrangements for community members.

Earlier coverage referenced in the source material indicates that scrutiny has been ongoing, including questions about how the campus fits within existing legal frameworks. The current license revocation and the potential loss of Malaysia Digital status suggest authorities are not treating the matter as purely procedural.

Srinivasan denies shutdown claims and points to remediation

As the regulatory situation unfolded, Srinivasan denied reports that Network School was shutting down. According to the linked social media statement in the source material, he said Network School had received two notices: one reportedly requiring “change the text of a sign,” and another related to a coworking setup formed by combining two adjacent units, where one side had a valid license but the other did not.

Srinivasan said the issues fell within a remedial period and that the organization would remediate them, adding that its members were otherwise unaffected. Cointelegraph also notes that it reached out to Srinivasan and Network School for comment, but the provided text does not include any additional responses beyond the denial and remediation framing.

Advertisement

Interpreting these statements alongside the MBIP and MDEC actions reveals an important asymmetry: public guidance from local authorities and program administrators may move faster than a company’s internal remediation plan. In practical terms, even if a remedial path exists on paper, the uncertainty can still disrupt hiring, occupancy, and community planning—especially for international residents who rely on predictable compliance timelines.

Meanwhile, Dragonfly Capital managing partner Haseeb Qureshi, quoted in the source material, linked the “Malaysia drama” to the broader “network state” argument. He suggested that the outcome could be used to negotiate new arrangements with other jurisdictions—an interpretation Srinivasan appears to be leaning into as the Kazakhstan MoU emerges.

What to watch next for Network School

Readers should focus on two tracks as the story develops: whether MDEC’s Malaysia Digital revocation proceeds and how quickly Malaysia’s immigration inquiries translate into enforceable outcomes, and—on the other side—how Kazakhstan operationalizes the MoU into concrete regulatory approvals for a Network School campus. Until those details are clear, Network School’s ability to retain its community and recruitment momentum will likely depend on jurisdiction-by-jurisdiction compliance rather than a single global brand narrative.

Digital Chamber Sues Illinois Over 0.2% Crypto Tax Law

Published

on

US CPI Data is Critical for Bitcoin and Gold This Week

The Digital Chamber sued the Illinois Department of Revenue on Tuesday, asking a Sangamon County court to strike down the state’s new Digital Asset Tax Act before it takes effect.

The trade group represents more than 250 blockchain firms. It argues the 0.2% levy unfairly singles out digital assets based on the technology used to record ownership.

Inside Illinois’ Digital Asset Tax Act

Illinois enacted the Digital Asset Tax Act as Article 3 of Public Act 104-0468. The measure sets a 0.2% tax on the exchange, transfer, or storage of a customer’s digital asset.

Brokers must also register with the Department of Revenue. Violating the Illinois statute exposes them to Class 3 felony charges. The tax takes effect January 1, 2027.

Governor JB Pritzker signed Senate Bill 3019 into law in June. It drew heavy backlash from the crypto industry at the time, and the courts are now involved.

The Digital Chamber’s lawsuit raises six claims under state and federal law. It argues that the tax treats identical property differently based only on how ownership is recorded.

“Put simply, this tax discriminates against people who transact in digital assets,” the group said.

A tokenized Treasury and a book-entry Treasury carry the same rights, the suit says. However, only the blockchain version is subject to tax. The filing compares the setup to taxing one email system but not another.

The group also warns that the definition could stretch far beyond crypto. It says future state taxes could reach AI-enabled settlement systems and cloud-based payment networks.

“Taxes should be carefully considered, not only for the revenue they produce but for the fairness of those being taxed. That was not the case here, as the provision slipped into legislation the night before the bill’s final consideration,” CEO Cody Carbone said.

The suit asks the court to declare the Act void and block enforcement. A repeal bill, House Bill 5798, remains pending in the legislature.

Tracking Real User Activity: Why It Matters More Than Vanity Metrics

Published

Tracking Real User Activity: Why It Matters More Than Vanity Metrics

In the digital economy, numbers are everywhere. Websites report page views, social media platforms count likes and followers, and blockchain applications showcase wallet addresses and transaction volumes. While these metrics may look impressive, they don’t always reveal the true health of a product or ecosystem. The real indicator of success is real user activity—how actual people interact with a platform over time.

Whether you’re building a decentralized application (dApp), launching a Web3 protocol, or managing a traditional SaaS platform, understanding real user behavior is essential for sustainable growth.

What Is Real User Activity?

Real user activity refers to meaningful interactions performed by genuine users rather than bots, fake accounts, or one-time visitors. These interactions demonstrate actual engagement and value creation.

Examples include:

  • Returning to use an application regularly
  • Completing transactions
  • Providing liquidity
  • Participating in governance
  • Creating content
  • Referring new users
  • Making purchases
  • Using multiple features within the platform

Unlike vanity metrics, real activity reflects authentic adoption.

Why Vanity Metrics Can Be Misleading

Many projects celebrate milestones such as:

Advertisement
  • One million wallet addresses
  • Hundreds of thousands of followers
  • Millions of transactions
  • High website traffic

While these achievements may attract attention, they don’t necessarily indicate an active community.

For example:

  • Wallets can be created automatically.
  • Followers can become inactive.
  • Transactions can be generated by automated bots.
  • Website visits may last only a few seconds.

Without genuine engagement, these numbers provide limited insight into long-term success.

Key Metrics That Actually Matter

Instead of focusing solely on headline numbers, successful teams monitor indicators that reflect user behavior.

Daily Active Users (DAU)

Measures how many unique users interact with the platform each day.

Monthly Active Users (MAU)

Shows sustained engagement over a longer period.

Advertisement

Retention Rate

Tracks how many users return after their first visit or transaction.

High retention usually indicates that users find ongoing value.

Session Duration

Longer sessions often suggest users are actively exploring features rather than leaving immediately.

Feature Adoption

Understanding which tools users actually use helps prioritize future development.

Advertisement

Conversion Rate

Measures how many visitors become active participants, customers, or token holders.

Real User Activity in Web3

Tracking activity becomes more challenging in decentralized ecosystems because users may have multiple wallets and interactions occur across various protocols.

Useful on-chain indicators include:

  • Active wallet addresses
  • Repeat wallet interactions
  • Smart contract usage
  • Liquidity participation
  • NFT trading frequency
  • Governance voting participation
  • Staking duration
  • Cross-chain activity

Combining blockchain analytics with application-level data provides a much clearer picture of adoption.

The Role of Analytics Tools

Modern analytics platforms help developers understand user behavior while respecting privacy.

Advertisement

Common capabilities include:

  • Event tracking
  • User journey analysis
  • Funnel visualization
  • Cohort analysis
  • Retention reports
  • Heatmaps
  • Performance monitoring
  • Error tracking

In Web3, blockchain analytics platforms add visibility into wallet activity and on-chain interactions.

Why Retention Beats Acquisition

Acquiring new users is expensive.

Keeping existing users is far more valuable.

A platform with 10,000 loyal users who engage weekly often outperforms one with 500,000 one-time visitors.

Advertisement

Returning users:

  • Generate recurring revenue
  • Provide feedback
  • Build communities
  • Create organic marketing
  • Increase network effects

Retention transforms growth into sustainability.

Privacy Should Never Be Ignored

Tracking users should never come at the expense of personal privacy.

Responsible analytics emphasize:

  • Anonymous identifiers
  • Aggregated insights
  • Consent-based data collection
  • Transparent privacy policies
  • Minimal data storage

Emerging technologies such as zero-knowledge proofs (ZKPs) and privacy-preserving analytics enable platforms to measure engagement without exposing sensitive user information.

This balance is becoming increasingly important as privacy regulations continue to evolve worldwide.

Advertisement

Turning Data into Better Products

Collecting analytics is only the first step.

The real value comes from acting on the insights.

For example:

  • High abandonment during onboarding may indicate confusing instructions.
  • Low governance participation may suggest voting is too complex.
  • Frequent exits after connecting a wallet could reveal poor user experience.
  • Strong engagement with one feature may justify expanding that functionality.

Data-driven decisions help teams allocate resources more effectively.

The Future of User Activity Tracking

Artificial intelligence is making analytics more intelligent than ever.

Advertisement

Future platforms will increasingly:

  • Predict user churn before it happens
  • Recommend personalized experiences
  • Detect fraudulent behavior automatically
  • Identify growth opportunities in real time
  • Optimize onboarding using behavioral insights
  • Measure user satisfaction through interaction patterns

For decentralized applications, AI combined with blockchain analytics could create adaptive ecosystems that continuously improve based on genuine community activity.

Conclusion

Real user activity is the foundation of sustainable digital growth. While large numbers may generate excitement, consistent engagement, strong retention, and meaningful interactions reveal whether a platform is truly delivering value.

As Web3 and decentralized technologies continue to mature, projects that prioritize authentic user behavior over vanity metrics will be better positioned to build lasting communities, improve their products, and achieve long-term success. In an increasingly competitive digital landscape, understanding how real people use a platform isn’t just helpful—it’s essential.
