Özet

Polygon has just launched a new self-sovereign, zero-knowledge proof (ZKP) identity service. Called Polygon ID, the solution will enable users to verify their credentials and identity without ever revealing any personal information.

The solution aims to front-run the know-your-customer (KYC) regulation that will put incredible pressure on cryptocurrency companies around the globe.

A decentralized solution for KYC

Privacy and anonymity are the cornerstone of Web3 culture, representing everything its users hold dear. However, the huge growth seen in the Web3 market, driven by DeFi and NFT industries, has made it a target for regulators.

Market watchdogs around the globe have been racing to regulate the burgeoning industry and gain some semblance of control over its fast-growing market. This push for regulation translates into more stringent KYC requirements for companies operating in the Web3 sphere.

For crypto service providers, KYC means requiring their users to provide personally-identifying information such as passports, government-issued IDs, and biometric data. And while this relieves the pressure from regulators, it presents a slew of other problems, which include infringement of privacy and data leak risks.

This rising concern is what Polygon set out to address with its new ID solution. Polygon ID is one of the first such solutions to be powered by zero-knowledge (ZK) cryptography and represents the first milestone in Polygon’s ambitious roadmap for 2022.

The scalable blockchain platform has made zero-knowledge cryptography the centerpiece of its strategic vision for the next couple of years and has committed $1 billion to fund projects exploring and implementing the technology. Polygon ID, the company told CryptoSlate, is the latest product in this rapidly growing portfolio.

The ID solution will leverage the Iden3 protocol and the Circom ZK toolkit to provide a decentralized and self-sovereign platform for organizations, businesses, and users. It can be used to construct a variety of identity and trust services, including dAccess-as-a-Service, KYC and KYB attestation, as well as distribution channels.

For end-users, Polygon ID offers a decentralized way to KYC by enabling them to create a digital identity that can confirm their access rights without divulging their personal information. Polygon told CryptoSlate that this is a major step forward over traditional forms of digital identification as it removes all redundancy and middlemen from the process.

“Polygon ID is private by default, offers on-chain verification and permissionless attestation. There is nothing in the digital identity space now that ticks all these boxes,” said Mihailo Bjelic, Polygon’s co-founder. “It is also a great showcase for how zero knowledge proofs can help us create a better world.”

It also allows for the construction of new forms of reputation, opening up new possibilities for companies in the Web3 space. According to Polygon, its new ID solution can be used to provide decentralized credit scores for financial primitives and social payments in DeFi and enable a decentralized Sybil score that could create new decision-making and governance models in DAOs. Polygon ID could also be used to create player reputation profiles for Web3 games and facilitate private P2P communication and interactions on social applications.

Polygon’s convenient privacy set that’s set to be delivered this year

Based on the expressible claim standard, Polygon ID offers advantages over other forms of digital verification such as NFTs and verifiable credentials (VCs).

While NFTs have become ubiquitous in the Web3 world, they lack the privacy and cost-efficiency needed to make them an effective verification solution. Verifiable credentials, on the other hand, offer a higher degree of privacy as they enable selective disclosure and can support ZK cryptography. However, they’re limited when it comes to expressibility and composability—all features required when implementing verification solutions to complex applications.

And while zk-proof-based identity solutions offer significantly more benefits and applications, their complexity often stands in the way of mainstream adoption. Polygon ID has drastically reduced the complexity that comes with the use of Circom 2.0 and created a much more streamlined solution.

This enables the onboarding for developers and partners to take place via the ID client toolkit, which will come with native apps, SDKs, and white label solutions. On-chain private verification is done using zkProof Request Language, while identities can issue claims through the relayer, a unique model that reduces the cost of user claims.

To support all of these features, Polygon ID will be structured as a set of tools and platform services. The product portfolio will include the Polygon ID Wallet app, the Polygon ID platform, and the Polygon ID Connect, a public service platform that enables access integration across user wallets and apps.

By the end of the week, Polygon is set to deliver a proof of concept for the Polygon DAO. Next quarter, the market should see the public release of the ID Wallet app and the Polygon ID SDK, while the full release of the Polygon ID platform and the SDK for custom use cases should happen this fall.

The Impossible Trilemma Is Basically a Pseudo-Problem

The article argues that the core limitation of blockchain technology is not the scalability trilemma, but its fundamental lack of privacy, which acts as a barrier to institutional capital. It defines blockchain as a slow, expensive, shared computer whose primary value is "permissionlessness" (no administrator) and verifiable trust. While this is ideal for native financial assets like stable币, which now process trillions, two critical flaws remain for mainstream adoption: regulatory legitimacy and a default transparency that leaks all financial activity. The author contends that transparency is not a feature but a tax, quantified through MEV extraction, making the public ledger unusable for serious institutions. However, modern cryptography, specifically zero-knowledge proofs, now offers a solution: "provable privacy." This allows users to prove compliance (e.g., solvency, KYC) without revealing underlying data. This fusion of privacy and auditability resolves the transparency-compliant privacy-compliance dichotomy, enabling a purely upgraded system where transactions are verified but not broadcasted. Closing these flaws is presented as the essential bridge to onboard the next wave of trillions in capital.

The "Impossible Triad" Is Fundamentally a Pseudo-Problem

The article argues that blockchain's fundamental limitation is not the scalability trilemma (decentralization, scalability, security), which has been largely solved, but the lack of **privacy** and, until recently, clear **legitimacy**. Blockchain is described as a slow, expensive, globally shared computer whose core value is censorship resistance and verifiability. While ideal for native digital assets like money (e.g., stablecoins), its default transparency acts as a **tax**, exposing all transactions and enabling MEV extraction, which deters serious institutional capital. Simultaneously, its permissionless nature created regulatory ambiguity. The piece contends that **privacy** is the missing critical feature. It rejects the false choice between total transparency and complete anonymity. Modern cryptography (like zero-knowledge proofs) enables **compliant privacy**: users can prove facts (solvency, KYC status, compliance) without revealing the underlying sensitive data (specific holdings, identities). This preserves auditability for regulators and eliminates the leak of financial information. With recent regulatory progress (e.g., the GENIUS Act) addressing legitimacy, adding default, provably compliant privacy becomes a pure upgrade. It transforms blockchain from a costly, public ledger into a confidential settlement layer, finally bridging the gap to mainstream institutional and individual adoption of on-chain finance.

Optical Chips: Collective Capacity Expansion

The global optical chip industry is experiencing a massive wave of expansion driven by surging AI data center demand. Major players across the US, Japan, Europe, and China are aggressively investing to ramp up production capacity. In the US, Coherent is expanding its 6-inch Indium Phosphide (InP) semiconductor fab in Texas, supported by CHIPS Act funding and a $2 billion strategic investment from NVIDIA. Lumentum is building a new factory for InP optical devices, and Nokia is scaling its advanced photonic chip packaging and testing capabilities. NVIDIA's investments aim to secure future supply of critical lasers and optical interconnect products for AI infrastructure. Japan's JX Advanced Metals, a leading InP substrate supplier, plans a multi-billion yen investment to increase its capacity 7-10 times, strengthening its grip on the crucial upstream materials market. In Europe, IQE and Tower Semiconductor settled a patent dispute and signed a multi-year InP epitaxial wafer supply agreement, highlighting that next-generation silicon photonics platforms will integrate high-performance InP components. STMicroelectronics and Sivers Semiconductors are also expanding silicon photonics production and partnerships. China is rapidly building out its domestic supply chain. Dongshan Precision's subsidiary, Source Photonics, announced a $12 billion project to expand optical chip and module production. Companies like Sanan Optoelectronics and Yunnan Germanium are scaling up InP chip manufacturing and substrate production, moving towards vertical integration from materials to modules. While debate continues around the exact future architecture—whether CPO (Co-Packaged Optics), NPO, or pluggables will dominate—analysts like Morgan Stanley argue the underlying driver is unchangeable: the explosive growth in bandwidth demand. This will inevitably increase the volume of optical engines, lasers, and related content per GPU, regardless of the final technical path. The competition for "more light" in the AI era has intensified into a global, full-chain capacity race.

Stablecoins Finally Find Real Yield: An In-Depth Look at On-Chain Reinsurance Re | A Conversation with Re Founder Karan Saroya

Stablecoin Real Yield Found: A Deep Dive into On-Chain Reinsurance with Re's Karan Saroya As stablecoin supply exceeds $170 billion, the search for sustainable, non-speculative yield intensifies. Re, an on-chain reinsurance platform, provides an answer: connecting stablecoin capital to the trillion-dollar traditional reinsurance market. Re operates as a regulated reinsurer, accepting stablecoin deposits as collateral to back US insurance companies. These insurers pay premiums, generating yield that flows back to on-chain depositors. Currently supporting 35 insurers and underwriting $500 million, Re projects scaling to over $1 billion soon. Key insights from a Bankless podcast with founder Karan Saroya and investor Avichal of Electric Capital: 1. **Uncorrelated, Real-World Yield:** Re offers stablecoin holders access to reinsurance returns (targeting 12-14%+), an asset class entirely separate from crypto or equity markets. 2. **Operational Efficiency via Smart Contracts:** Re replaces traditional, labor-intensive capital fundraising with smart contracts, allowing a ~12-person team to compete with industry giants. 3. **Regulatory Leverage:** For every $1 of collateral, regulations allow backing $5-7 in written premiums. This leverage amplifies returns from the underlying risk-free rate. 4. **DeFi Integration:** Depositors receive receipt tokens, which can be used in protocols like Morpho for "looping," potentially pushing yields to 18-20%+. 5. **The "DeFi Mullet" Model:** A compliant front-end (regulated reinsurer) paired with a decentralized back-end (smart contracts, DeFi capital markets). 6. **RE Governance Token:** Modeled on Lloyd's of London, the token governs the central capital pool's allocation, counterparty acceptance, and parameters. 7. **Real Economic Impact:** Capital funds real-world productivity (factories, clinics, businesses) via insurance, moving beyond crypto's internal loops. The discussion highlights a pivotal moment: DeFi's supply-side infrastructure is now met by real demand for productive yield, potentially kickstarting a flywheel where vast on-chain stablecoin capital seeks these real-world returns.

1996 or 1999? Walsh's First Test is 'How to View AI'

"1996 or 1999? Wall's First Big Test Is 'How to View AI'" Federal Reserve Chairman Wall's initial challenge is not whether to raise or cut rates, but a more fundamental judgment: what kind of boom is the current AI boom? This will determine the Fed's policy path and define his legacy. Economics is split between two opposing views, according to reporter Nick Timiraos. One sees imminent productivity gains that will increase supply and cool inflation, allowing the Fed to hold steady. The other argues that while productivity benefits are distant, demand shocks are here now, and waiting for data confirmation risks missing the intervention window, forcing sharper rate hikes later. Wall has signaled a leaning toward the first view, echoing 1996-era Alan Greenspan, who embraced strong, productivity-driven growth without fear of inflation. However, Wall faces a different macro environment than Greenspan did, with tariff pressures, expanding fiscal deficits, and diminishing globalization benefits, which could force more significant inflation pressures even if AI benefits materialize. Wall's logic, expressed before taking office, is that AI-driven productivity gains won't show in official data for years. If the Fed waits for confirmation, it might mistakenly tighten policy and choke off the very growth that could suppress inflation. This argues for using forward-looking narratives over lagging data. Chicago Fed President Austan Goolsbee presents a key counter-argument. He distinguishes between expected and unexpected productivity booms. A widely anticipated boom, like the current AI wave, can cause people to spend future wealth gains in advance, overheating the economy before productivity actually rises, thus requiring preemptive rate hikes. He cites rising costs for AI data centers as evidence of such overheating. Fed Governor Christopher Waller offers a rebuttal to Goolsbee, noting the "expected spending" mechanism only works if people can borrow against future income, which many households cannot do due to borrowing constraints. Wall also faces a paradox related to his desire to reduce the Fed's use of "forward guidance" (pre-announcing policy moves). This practice was established in 1999 when Greenspan began signaling hikes to avoid market shocks. If the economy follows a less optimistic path, Wall may be forced to choose between using the guidance he wants to abolish or risking market volatility by staying silent. The ultimate question defining Wall's first major test remains: Is this 1996 or 1999?
