Silencio DePIN: How a Polkadot-powered data network turns smartphone noise readings into real-world value
Silencio is a Decentralized Physical Infrastructure Network (DePIN) that pays people to measure ambient noise with their phones, building a global noise-level dataset for cities, real estate, hospitality, and research. Built on peaq (a Polkadot ecosystem chain), it combines an easy mobile app, business-ready data products, and tokenized incentives.
What is Silencio (and why it matters)
Silencio is a DePIN that turns everyday smartphones into noise-level sensors. Users measure ambient decibel levels via the app, help build a global noise map, and earn rewards (such as $SLC airdrops and gamified raffles). This creates a privacy-preserving, crowdsourced data layer that helps people choose quieter homes, locate calm restaurants, and plan healthier cities.
Silencio runs on peaq, a Polkadot ecosystem chain that acquires blockspace on Polkadot via Coretime (active parathread status). That gives Silencio access to Substrate tooling and Polkadot’s scalability roadmap while keeping DePIN-specific functions close to the protocol layer.
As of recent coverage, public trackers and community posts have reported 300k–370k+ users across 180+ countries—evidence of rapid adoption for a no-extra-hardware model. (Figures vary by source and date; always time-stamp stats when you cite them.)
ELI5: Silencio in one minute
- People use a phone app to check how loud their surroundings are—like a decibel speedometer.
- Those readings (not voice recordings) go to a shared map that shows typical noise levels for streets and places.
- Contributors earn rewards, and city planners, hotel brands, and renters get useful, up-to-date noise insights.
How Silencio works
- Data collection: Users start a measurement session in the mobile app; the phone logs dB(A) values tied to time and approximate location. Documentation emphasizes Silencio does not record audio content—it captures numeric sound-level data only.
- Privacy & consent: Silencio describes dissociating sound-level data from usernames, offering users the ability to view/delete their data, and a privacy-first design. App store disclosures indicate no data collected/shared for the app; always verify per your jurisdiction.
- On-chain settlement & rewards: Activity and incentives are anchored on peaq, a Polkadot ecosystem chain built for DePIN. Users can participate in leagues, airdrops, and monthly raffles denominated in $SLC (Silencio’s token).
- Distribution & growth: Partnerships such as preinstall programs on budget smartphones are designed to place DePIN apps directly in users’ hands in emerging markets—an adoption lever for supply-side growth.
Key features
- Mobile app (iOS/Android): Measure ambient noise; gamified Leagues; referrals; earn in-app coins and $SLC airdrop eligibility (subject to regional rules).
- Explorer: Public noise maps to compare neighborhoods, venues, and trends.
- Privacy-preserving measurements: Numeric dB(A) only; whitepaper and policy emphasize anonymization and opt-out.
- Tokenized incentives: $SLC distribution via raffles/airdrops with clear disclaimers. Not investment advice.
- Polkadot/peaq alignment: Built atop peaq (Polkadot ecosystem, active Coretime parathread), giving Silencio a credible, modular DePIN base.
Silencio toolset comparison
| Tool | Primary purpose | Who it’s for | Data produced | Earning mechanics | Access |
|---|---|---|---|---|---|
| Silencio App | Capture noise levels via phone; contribute to map | General users, citizen scientists | dB(A) time/location series (no audio) | In-app coins, Leagues, $SLC airdrop eligibility | iOS/Android stores |
| Explorer | Visualize noise trends by area/venue | Renters, travelers, city teams | Aggregated noise layers & heatmaps | None (view only) | Web explorer (from app/site) |
| Chrome Extension | Lightweight measurements/utility in browser | Power users, reviewers | Session readings | Indirect (account-bound) | Listed via app/site |
| Leagues & Raffle | Gamified engagement & distribution | App users seeking rewards | N/A | Monthly raffles; airdrops; referral boosts | In-app events & rules |
Who uses the data (use cases)
- Urban planning & smart cities: Identify hotspots, plan mitigation, monitor after interventions.
- Real estate & PropTech: Compare locations by typical noise exposure; enhance property discovery with objective acoustic profiles.
- Hospitality: Help travelers find quieter hotels/cafés; benchmark venue ambience for brand standards.
- Public health & research: Study correlations between noise exposure and outcomes (sleep quality, stress, cardiovascular risk) using large-scale, hyperlocal signals.
- Mobile growth channels: Low-cost smartphone preinstalls drive participation in emerging markets—critical for geographic coverage.
Step-by-step: start earning with Silencio
- Install & sign up (iOS/Android).
- Run a measurement session: Keep the phone out of your pocket, at chest height if possible; walk the target area for several minutes to log stable readings.
- Submit & review: Check the map layer for your contributions; repeat at different times of day to capture variability.
- Engage Leagues & referrals: Join Leagues, participate in monthly raffles, and invite friends (subject to local rules).
- Stay compliant: Read the airdrop disclaimer and local regulations. This isn’t investment advice.
Example: run a “quiet venues” campaign in one district
- Scope: 25 restaurants in a tourist zone; measure evening dB(A) for 7 days.
- Plan: Recruit 30 local contributors; provide a simple route; enforce privacy and measurement protocol.
- Metrics: Median & 95th-percentile dB(A) per venue; peak times; “quietest night” badge.
- Outputs: Public mini-map; listicle “Top 10 quiet cafés”; share with tourism board.
- Iteration: Repeat post-renovations or seasonal changes; compare deltas.
Common pitfalls & tips
- Assuming voice is recorded: Silencio emphasizes numeric sound levels only, not conversations.
- Pocket measurements: Obstructed mics skew results—keep the phone exposed during walks.
- One-off sessions: Noise varies by time/day; collect recurring samples to improve reliability.
- Regulatory blind spots: Airdrop eligibility differs by country; read disclaimers. Not investment advice.
- Over-claiming user numbers: Sources differ (e.g., 300k+ vs 370k+). Always date-stamp figures you publish.

FAQs
1) What chain is Silencio on? Silencio runs on peaq, a Polkadot ecosystem chain that acquires blockspace on Polkadot via Coretime (active parathread).
2) Does Silencio record my voice? No. The system collects numeric dB(A) noise-level metrics rather than audio content, with anonymization and user controls.
3) How do I earn? Run measurement sessions to earn in-app coins, join Leagues, and become eligible for $SLC airdrops/raffles where permitted.
4) Is $SLC listed anywhere? Listing data may be available on aggregators. Always verify latest listings and liquidity before transacting. Not investment advice.
5) How big is the network? Public reports vary from 300k+ to 370k+ users depending on date/source. Cite your source and include a timestamp when publishing.
6) Where can I see the maps? Use the app/site Explorer to view aggregated noise layers and venue insights.
7) Is there a growth plan for emerging markets? Yes. Preinstallation on affordable smartphones is one path to expand supply-side data collection and geographic coverage.
8) What about privacy compliance? Silencio communicates privacy-by-design, anonymization, and user controls. Check local regulations and app store disclosures for details.
Conclusion
Silencio shows how DePIN + Polkadot can turn everyday phones into environmental sensors that pay people for data with clear privacy guarantees. For builders and ecosystem teams, it’s a case study in no-hardware growth, city-grade datasets, and tokenized participation atop peaq.
