VXPass opens blockchain-based COVID-19 vaccination verification program to licensed medical practitioners and their patients

VXPASS, a blockchain-based platform built to manage, store and verify records for global COVID-19 vaccination programs, has today announced that it is opening its Digital Covid Card replacement to licensed medical practitioners and their patients all around the world. By opening the service to medical professionals directly, licensed practitioners can now offer patients the ability to record their vaccination records to a shared database on-chain, enabling them to hold and securely share their vaccination records digitally as needed, such as via a smartphone, without exposing their personally identity.
VXPASS as a platform allows medical professionals to securely document a patient’s status during the course of their personal COVID-19 vaccination program by creating a digitally signed version of the COVID-19 vaccination cards. Without storing any personally identifiable information, VXPass creates a record of all relevant vaccine data (including the type of vaccine given, the time each dose was administered) on the BSV blockchain, using techniques that protect patient privacy. The data application enables government bodies and health organizations to better monitor their vaccination programs in real-time while also giving control over access to
The process of writing the vaccination details to the blockchain using VXPASS can be undertaken by the medical practice as part of the service they offer to their patients, meaning that patients will not need to interact directly with the blockchain. With today’s new service offering, medical practitioners can now use the service to create digital records of new vaccinations as they occur, as well as digitizing existing vaccination records.
VXPASS will offer tokens (built using RelayX and available for pre-sale immediately on both RelayX and VXPass.com) which will entitle users to have their vaccination records written to the blockchain using the VXPASS platform at participating medical practices starting at $4.99. Participating medical practitioners may offer this service directly within their practices also. In the future, VXPASS will begin rolling out virtual visits with local doctors for those patients whose doctors are not currently enrolled.
Speaking on today’s announcement, Zachary Weiner, founder of VXPASS, said:
“At present, paper cards are the only way that most people are able to keep a record of their vaccinations. They’re not only inconvenient and unreliable, but in many places, not acceptable as a valid proof of vaccination. With VXPASS, we solve that issue by digitizing vaccination records and placing them in the patient’s custody, on the blockchain. This creates an immutable and verifiable signed record of a patient’s vaccination which can be accessed and securely shared by them, anywhere at any time. Initially, VXPASS focused on creating secure patient owned records at the time of vaccination, but with today’s announcement, our platform is now able to offer that same simplicity and security to all patients holding a valid record of vaccination record – something we see as a crucial step to putting the pandemic in the past and moving forward with our collective futures.”
Also speaking, Jimmy Nguyen, Founding President of Bitcoin Association – the global industry organization that works to advance business with the BSV blockchain, said:
“The team at VXPASS have built an effective tool which leverages the power of the BSV blockchain to track vaccination records in a way which is more accurate and more efficient, without sacrificing patient privacy – demonstrating the tangible benefits that blockchain technology can offer today to empower personal health care data.”

Blocks & Headlines: Today in Blockchain – May 16, 2025

A Pivotal Moment for Blockchain’s Many Frontiers
Today’s briefing arrives at a crossroads in blockchain’s evolution. From AI-driven Layer-1 grant programs to gamified resets in Web3, from supply-chain trust revolutions to exchange-driven token incentives, and high-stakes regulatory leadership shifts, the industry is charting new territory on multiple fronts. As builders, investors, and policymakers navigate this shifting terrain, five stories stand out for their potential to reshape blockchain’s trajectory:
-
Lightchain Protocol AI unveils a $150,000 developer grant program to onboard top builders in AI × blockchain.
-
Blockchain gaming experiences its lowest engagement of 2025, signaling a sector reset toward sustainability.
-
Norwegian Seafood Council research highlights blockchain’s trust-building power in global supply chains.
-
MEXC Exchange announces the Einstein (EIN) listing on July 20, 2025, buoyed by a $50 million rewards event.
-
Summer Mersinger, a US CFTC commissioner, is tapped as CEO of the Blockchain Association, marking a pivotal regulatory turn.
In this op-ed–style briefing, we’ll unpack each development, explore its implications for blockchain, cryptocurrency, Web3, DeFi, and NFTs, and assess how these narratives intersect to define today’s momentum.
1. Lightchain Protocol AI’s $150K Grant: Catalyzing Decentralized Intelligence
What happened: On May 15, 2025, Lightchain Protocol AI—a Layer-1 blockchain optimized for AI workloads—launched its Developer Grant & Ecosystem Incentive Program, pledging up to $150,000 in total funding to on-board teams building dApps, explorers, wallets, analytics dashboards, DeFi protocols, NFT platforms, and AI-powered modules on its network. Grants are milestone-based (up to $5,000 per milestone), accompanied by technical support, co-marketing, and ecosystem visibility. Source: Bitcoin News
Why it matters: Lightchain’s move underscores the growing fusion of AI and blockchain. By allocating resources to builders at the intersection of these technologies, the protocol signals that the next wave of innovation will hinge on intelligent smart contracts, federated learning coordination, and on-chain decision-making. For developers, this grant lowers barriers to entry and emphasizes sustainable, value-driven growth over token speculation.
> “We’re seeking impactful projects that align with Lightchain AI’s goal of bridging AI and blockchain—everything from AI prediction markets to compute marketplaces.” > — Lightchain Protocol AI Core Team
Implications:
-
DeFi & NFTs: Expect AI-augmented lending protocols and NFT platforms with dynamic metadata driven by on-chain models.
-
Ecosystem Growth: Lightchain’s aggressive grant strategy may spur competitors (e.g., Ethereum layer-2s) to bolster their own builder incentives.
-
Governance & Sustainability: The milestone-based approach aligns funding with tangible progress, a model DeFi DAOs may increasingly adopt for resource allocation.

2. Blockchain Gaming’s 2025 Low: A “Reset” Toward Quality
What happened: According to Crypto.news, blockchain gaming saw daily active wallets dip to 4.8 million in April 2025—a 10% month-over-month decline and the lowest point of the year for Web3 gaming. Share of the DApp ecosystem for gaming fell to 21%, now tied with DeFi, while AI projects surged to 16% of on-chain activity. Funding also plunged nearly 70% from March to $21 million in April, though Arbitrum Gaming Ventures deployed $10 million from its $200 million fund to support titles like Wildcard, XAI Network, and Proof of Play.

> “Capital is harder to secure, but that’s not necessarily bad. Weak projects are falling away, and funds are flowing into builders laying the groundwork for the next generation of blockchain games.” > — Sara Gherghelas, DappRadar Analyst
Why it matters: The downturn reflects a market recalibration from token-centric models toward user engagement, game mechanics, and interoperability—key for mainstream adoption. High-profile missteps (e.g., Square Enix shelving Symbiogenesis, Sega’s experimental launch of KAI: Battle of Three Kingdoms) contrast with enduring partnerships like Ubisoft + Immutable’s Might & Magic card game.
Implications:
-
DeFi and Gaming Convergence: As DeFi’s share remains steady, expect crossover innovations (e.g., on-chain staking integrated into gameplay).
-
Investor Focus: Sustainable tokenomics over ‘yin-yang’ hype; capital will favor projects with robust retention metrics and revenue models.
-
NFT Utility: Gaming’s reset may accelerate evolution of NFTs beyond collectibles into dynamic, utility-driven assets.
