XION launched DKIM and ZK dual modules, becoming the first blockchain to store email authentication keys on-chain

XION recently published an article introducing its new infrastructure and application scenarios. XION announced the official launch of the DKIM module and the ZK module, becoming the first blockchain to directly store email authentication keys (DKIM) on-chain, as well as the first consumer-grade L1 public chain to implement zero-knowledge verification at the protocol level.XION pointed out that existing email verification solutions (including projects like zkEmail) rely on centralized DNS servers to obtain encryption keys. When email service providers rotate keys, the old verifications become invalid, and there are no historical records available. XION's DKIM module permanently stores these keys in the on-chain state, completely eliminating the reliance on centralized DNS infrastructure. Its ZK module implements zero-knowledge proof verification at the protocol level, achieving an efficiency that is 10 times that of smart contract solutions. The two work together, allowing users to prove any information in an email without exposing the email itself.XION stated that currently about 61% of employees who witness misconduct remain silent, as traditional options are often "anonymous but ignored" or "speak up but risk unemployment." With the above infrastructure, XION has realized various application scenarios, including:Anonymous reporting and workplace evaluations (proving employment status without exposing personal information)Wallet recovery without mnemonic phrases (using email as a backup key)Purchase behavior and certificate verification (without excessive sharing of personal information)Trust-based ticket resale and insurance claims, etc.It supports Gmail and Apple Mail from launch, covering approximately 3.8 billion email users globally (accounting for over 90% of the global email market). Currently, the XION platform has over 800,000 monthly active users, with more than 150 brands including Uber, Amazon, and BMW already onboarded. The official statement claims this is a verification infrastructure built for the existing internet, "capable of verifying anything while leaking zero information."

Brevis co-founder Michael: In the next decade, 99% of blockchain computing will move off-chain, and ZK proofs will become key infrastructure

At the "Build and Scale in 2026" themed forum held by ChainCatcher in Hong Kong, Michael, co-founder & CEO of the ZK verifiable computing platform Brevis, delivered a keynote speech on "The Infinite Computing Layer Where Everything Can Be Computed," sharing how ZK technology is driving a fundamental transformation in the blockchain computing paradigm.Michael pointed out that the current on-chain computing costs are high and the speed is slow. The "verifiable computing" paradigm proposed by Brevis can offload heavy computations to off-chain, requiring only low-cost verification on-chain, achieving decoupling of computation and verification while supporting privacy protection scenarios.The speech showcased the performance breakthroughs of Brevis's core product, Pico ZKVM: its latest generation, Pico Prism, can complete Ethereum block proofs in an average of 6.9 seconds, with 99.6% of blocks completed within 12 seconds, achieving real-time proof (RTP) for Ethereum for the first time. Currently, Pico ZKVM, as an "on-chain ZK data co-processor," has been applied in various scenarios such as privacy-preserving incentive distribution, high-performance DeFi, and trustless on-chain data computation, providing Rust programming support for developers with zero ZK development experience.Michael predicts that in the next 10 years, 99% of blockchain computing will occur off-chain, verified through ZK proofs. Brevis is driving this process through its verifiable computing infrastructure.

a16z partner: Still坚持长期主义 in crypto investments, believing that after the popularization of blockchain finance, other categories of apps will emerge

a16z partner and a16z crypto leader Chris Dixon published an article on social media titled "The Long Game of Cryptocurrency," stating: There is a popular saying that the non-financial use cases of cryptocurrency are dead. Some also claim that the "read-write-own" model has failed. These conclusions misunderstand the core concepts and misjudge the stage of development we are in.We are currently in the financial era of blockchain. But the core idea has never been that all crypto applications will emerge simultaneously, nor that finance will not lead the way. The core thought has always been that blockchain introduces a new primitive—capable of coordinating human and capital at internet scale, embedding ownership directly into the system. Finance is the domain where this primitive can most naturally prove its value, which is why we often cite finance as the primary example of productive use cases for tokens.Finance is not separate from a larger vision; it is part of it. It serves as the foundation and testing ground for all other applications. At a16z and a16z crypto, we are looking long-term: our fund structure is designed for a cycle of over 10 years because building new industries takes time—operational sequence is crucial. Infrastructure and distribution networks often emerge before new categories of applications.The internet did not begin with social media, streaming, or online communities; it began with packet switching, TCP/IP, and basic connectivity. Only after hundreds of millions of people went online did entirely new cultural and economic categories emerge. Cryptocurrency is likely to be similar. A reasonable speculation is that we need to onboard hundreds of millions of people through financial applications like payments, stablecoins, savings, and DeFi before we can see meaningful adoption in media, gaming, AI, or other potentially more distant fields.Many applications rely on ready wallets, identities, liquidity, and trust mechanisms. This is why a16z has spent over five years working to establish a clear regulatory framework for tokens. Great endeavors take time. The breakthroughs we see today in the AI field are the result of decades of hard work by outstanding talents. Building a new technological system is a marathon, and this is what a marathon looks like in practice: a long period of groundwork followed by a sharp turning point. It is those chaotic years that make the clarity of the future possible.
