Brainstem brings Web3 fitness trackers to the Economy of Things on peaq
peaq, the Web3 network powering the Economy of Things, announces the expansion of its ecosystem as Brainstem Digital Health joins in to decentralize health data distribution. Brainstem is a scalable decentralized platform for collecting health data from wearable devices. Integration with peaq will see its devices outfitted with self-sovereign peaq IDs, which will be used to sign the data for authentication. Brainstem will also enable the community to monetize their health data on peaq’s instance of the Gaia-X data marketplace. Health wearables will make up a decentralized physical infrastructure network (DePIN) for gathering privacy-first health data on peaq.
The fitness and health tracker market is growing rapidly and will soar to $187.2 billion by 2032, according to Market.us. Health data collected on wearable devices is becoming increasingly valuable as AI rapidly transforms the healthcare landscape. However, legacy technological solutions and approaches represent a challenge to the sector. The Web2 healthtech industry has already produced such stories as hackers getting access to users’ GPS data and a fitness app revealing the locations of US military bases. Web3 privacy preservation will be a critical component that safeguards against risky Web2 data collection practices.
Brainstem is working to bring Web3 data handling to the health and fitness tracker market using the DePIN model, which crowdsources real-world hardware through token incentives. Its wearables will facilitate the collection of heart rate, heart rate variability, pulse oximetry, movement, blood pressure, and ultimately a range of other health metrics. Brainstems users who opt to share their anonymized data will earn rewards in crypto while providing researchers focusing on wellbeing with valuable data. This ecosystem will work as a global DePIN for collecting and monetizing privacy-first health data.
The integration with peaq will enable Brainstem to achieve this by leveraging peaq’s machine-oriented Web3 tools and functions. As a first step, Brainstem will link its app with the peaq network’s testnet. It will also add support for wallets compatible with peaq and update the app’s interface to work with them. Brainstem will outfit all of the wearables in its DePIN with decentralized peaq IDs, which the devices will use to sign the data they collect. Finally, it will enable the community to share and monetize their data on peaq’s instance of the Gaia-X data marketplace. Brainstem users will also be able to earn extra rewards from peaq’s mechanism redistributing a fraction of the network fees between connected device owners.
The Gaia-X market integration will connect the Brainstem DePIN with the EU-backed project bringing top enterprises, research institutions, and Web3 startups together. Gaia-X is working toward ensuring Europe’s digital sovereignty and moving the tech space toward more transparency and privacy. As part of moveID, a Bosch-led project in the Gaia-X 4 Future Mobility family, peaq is co-creating the standards and infrastructure for connected mobility of tomorrow.
“Health and Fitness trackers are capable of collecting troves of accurate, objective data that can help inform healthcare and wellness professionals and researchers, but this shouldn’t come at the expense of privacy,” says Brainstem’s co-founder Max Campbell. “We are changing the paradigm by providing a tool that empowers individuals and gives them full control and ownership over their data. peaq is a perfect home for our project thanks to its DePIN focus and device-centric features and economics that will enable us to build and scale fast.”
“The AI revolution has a lot in store for health and wellness, but it needs quality and privacy-compliant data for that,” says Till Wendler, co-founder of peaq. “Brainstems solves this puzzle by leveraging the Web3 stack. We are excited to see it join the peaq ecosystem and are confident it will bring a lot of value to the community.”

Blocks & Headlines: Today in Blockchain – May 30, 2025 (Fraser Edwards, Kyiv NFT, Spirit Blockchain Capital, Indian eHealth, Hedera)
Blockchain technology and cryptocurrencies continue to redefine industries—from competitive gaming and cultural heritage preservation to corporate finance, healthcare, and alternative tokens. Today’s briefing highlights five pivotal developments shaping the ecosystem: Fraser Edwards’s vision for trust in eSports; Ukraine’s wartime cultural preservation via NFTs; Spirit Blockchain Capital’s Q1 2025 operational report; India’s push for blockchain-enabled electronic health records (EHRs); and the rise of viral altcoins such as UniLabs, Sui, and Hedera Hashgraph. Together, these stories illustrate the themes of trust and identity, preservation and provenance, institutional maturation, public-sector innovation, and token diversification. In this op-ed–style round-up, we distill the essence of each story, cite sources, and offer analysis on how they advance Web3, DeFi, and NFT frontiers.
1. Rebuilding Trust in eSports: Can Blockchain Fix Competitive Integrity?
Source: CCN
Summary:
In a recent CCN interview, veteran trader and eSports investor Fraser Edwards argues that blockchain’s immutable ledgers can restore credibility in the rapidly commercializing world of competitive gaming. According to Edwards, match-fixing scandals and opaque prize-pool distributions have eroded fan confidence. By tokenizing tournament entries and payouts on public blockchains—complete with smart-contract–enforced escrow—organizers can guarantee that prize monies are distributed exactly as advertised, and that no post-match manipulation occurs. Tournament operators in Asia and North America are already piloting Ethereum-based payout dApps, aiming to increase transparency for players and sponsors alike.
Key details & analysis:
-
Smart-contract escrow: Funds are held in a time-locked contract that releases prize money only upon verifiable match results. This prevents disputes over referee decisions or delayed payments.
-
On-chain reputation: Player and team reputations can be tokenized via non-fungible reputation badges that accrue based on fair play and community votes—discouraging cheating.
-
Scalability concerns: High-traffic tournaments may require Layer 2 rollups or alternative chains (e.g., Polygon, Immutable X) to reduce gas costs and latency.
Opinion: Blockchain’s dual promise of provable fairness and programmable finance makes it uniquely suited to eSports. Yet adoption hinges on UX: seamless wallet integrations, minimal transaction fees, and clear regulatory guidance on esports tokens.
2. When Art Meets Blockchain: Ukraine’s Wartime Cultural Preservation
Source: The Kyiv Independent
Summary:
As monuments crumble under artillery fire, Ukrainian curators and technologists are partnering to mint NFTs representing lost or endangered artifacts. The Kyiv Independent reports that the National Art Museum of Ukraine has launched “Project Phoenix,” tokenizing high-resolution 3D scans of sculptures, manuscripts, and paintings. Proceeds from initial sales fund restoration and digital archiving efforts. Each NFT embeds provenance metadata—including GPS coordinates, curator notes, and condition reports—ensuring that future generations can verify authenticity and context, even if the physical artifact is destroyed.
Key details & analysis:
-
Metadata richness: Beyond simple ownership, NFTs store structured metadata—using ERC-721 metadata extensions—that capture curatorial insights and conservation logs.
-
Decentralized archives: IPFS and Arweave are employed to host ultra-high-resolution imagery, with on-chain hashes guaranteeing data integrity.
-
Community engagement: Fractional-NFT drops allow diaspora communities to collectively own tokens, strengthening cultural ties and crowdfunding preservation.
