The open universal standard for atmospheric exposure data.
No hardware required. No licensing fees. Runs on any device.
BXP is to breath exposure data what HTTP is to the web.
Air pollution kills more people than HIV, malaria, and tuberculosis combined. The tools to fix this exist. The data infrastructure does not. Until now.
Every device, application, and government agency stores air quality data in a different, incompatible format. A sensor in Accra cannot speak to a hospital in Nairobi. A reading in Delhi cannot contribute to a map in London. The data exists — but it cannot connect.
The largest air quality platforms maintain closed, proprietary data ecosystems. Researchers pay thousands to access data that should be public. Governments cannot share readings across borders. Innovation is blocked by licensing walls built for profit, not for people.
97% of air quality monitoring infrastructure is concentrated in wealthy nations. The populations suffering the most — in West Africa, South Asia, Southeast Asia — have the least data, the fewest tools, and the least power to hold polluters accountable.
HTTP gave us the web. PDF gave us documents. MP3 gave us audio. SSL gave us security. None of these required you to build hardware. Each became the foundation an entire industry was built on. Air exposure data has never had its HTTP. Until BXP.
BXP is a pure software protocol standard. It defines a universal file system architecture and data format for the capture, storage, transmission, and interpretation of atmospheric exposure data.
No sensors required. No hardware required. No centralized infrastructure required. BXP runs on any phone, any device, any platform, anywhere in the world — and it costs nothing to adopt.
It unifies data from government monitoring stations, satellites, existing sensor applications, phone-native sensors, and community reports into one open, portable, verifiable standard.
BXP defines a complete lifecycle for air exposure data — from the moment a reading is captured to the moment a community is protected.
Every BXP record is geographically anchored using the Geohash coordinate system. Minimum precision 5 (~4.9km cell). Recommended precision 7 (~153m). The entire planet is addressable. No location is excluded.
BXP accepts data from any source — government stations, satellites, existing sensor apps, phone-native sensors, or human observation. Three capability tiers ensure every reading has an appropriate quality flag. No source is excluded.
Raw data is normalized to BXP canonical units, corrected for temperature and humidity, and passed through automated quality control. The result is clean, comparable, trustworthy data regardless of source.
Technical measurements are translated into the BXP risk framework — six levels from CLEAN to HAZARDOUS, with specific protective actions for each. The BXP_HRI composite index incorporates all available agents for a complete picture of risk.
Individual observations become collective intelligence. Community reports combine human observation with sensor data — smoke color, odor type, physical symptoms, event tags, photo evidence. One person's reading. A million people's map.
BXP v2.0 covers every major atmospheric threat to human health — from microscopic fine particulates to invisible carcinogenic gases to biological agents that conventional monitors ignore entirely.
Every great standard in history succeeded because it removed the barrier of hardware dependency. BXP follows the same principle. The format is the invention — not the device.
Any existing data source can write BXP-formatted data immediately. The entire installed base of air quality infrastructure in the world becomes BXP-compatible the moment its developers adopt the standard.
BXP defines a standardized risk communication framework that translates any combination of technical measurements into clear, actionable guidance — in any language, for any population, anywhere on Earth.
Your exposure data is your health data. BXP treats it with the same seriousness as medical records — encrypted, private, yours to delete at any moment.
Personal exposure records encrypted by default. Your data cannot be read by anyone — including the server hosting it — without your credentials.
AES-256-GCMAll data in motion is protected with the most current encryption standard. Older, vulnerable protocols are rejected at the connection level.
TLS 1.3 MandatoryEvery reading can be cryptographically signed by its source device. Signed readings cannot be forged, altered, or attributed to a different origin without detection.
Ed25519 SignaturesPerson identifiers are never stored in plain form. Only SHA-256 hashes. Location precision for personal records defaults to neighborhood-level, not street-level.
SHA-256 + k-anonymityComplete permanent deletion of all personal exposure records with a single API call. Deletion is cryptographically verifiable. No shadow copies. No backups. Gone.
GDPR CompliantEvery BXP volume maintains a Merkle tree of all file checksums. Any tampering — with any file, anywhere in the volume — is instantly detectable without reading all data.
Merkle Tree VerificationBXP is a living standard. Each version expands the protocol's reach while maintaining perfect backward compatibility with everything that came before.
Open standards do not prevent commercial success. They enable it. Every major standard in history — HTTP, PDF, MP3 — created billion-dollar ecosystems around a free core. BXP is designed with the same architecture.
Any manufacturer, developer, or organization that wants to display official BXP compliance certification goes through the BXP Foundation. Standards certification is one of the most durable revenue models in technology history.
Revenue model: per-product certification feesThe official BXP cloud infrastructure. Organizations that need a managed, compliant BXP volume without running their own server subscribe to the BXP hosting service. Free for individuals. Paid for enterprises and governments.
Revenue model: SaaS subscription tiersThe inventor of a standard is the world's foremost expert on it. Hospitals, governments, smart cities, and sensor manufacturers pay premium rates for implementation guidance from the source.
Revenue model: enterprise consulting contractsWHO, the Gates Foundation, the Wellcome Trust, USAID, and the African Development Bank fund open health infrastructure that serves underserved populations. BXP is exactly this. Non-dilutive. No equity given up.
Revenue model: institutional grant fundingAggregated, anonymized atmospheric intelligence derived from the BXP network. Public health researchers, insurers, urban planners, and climate organizations pay for access to population-level exposure insights.
Revenue model: data licensing and API accessWhen BXP becomes the standard — and standards this well-designed always do — phone manufacturers and OS developers will build BXP support natively. Apple Health, Google Fit, Samsung Health. That moment creates extraordinary partnership and licensing value.
Revenue model: platform partnerships and licensingBXP was not born in a well-funded lab or a corporate R&D department. It was born from the observation that the most important infrastructure for human health — the data layer that tells us what we are breathing — simply did not exist.
The communities that breathe the worst air have the least data about it. The populations most at risk are the least equipped to measure, understand, or respond to their exposure. BXP exists to close that gap permanently — and to do it with a tool that costs nothing and works everywhere.
The standard is open. The mission is clear. The work has begun.
The original Breathe Exposure Protocol specification and working Python implementation published on GitHub by Elvarin. Core concepts established: user-owned data, offline-first, SHA-256 verification, portable containers. Version 1 is permanently frozen as the origin record.
Complete expansion into a production-ready global standard. Full file system architecture, 31-agent schema, REST API specification, security framework, BXP_HRI formula, governance model, and compatibility with every major existing air quality standard.
Reference implementations, SDKs, mobile applications, and the first BXP-compatible tools. The specification becomes software. The software becomes infrastructure. The infrastructure becomes the standard the world uses.
BXP is governed by the BXP Foundation — an open standards body with no commercial bias. Every developer, researcher, organization, and individual is welcome to contribute, propose changes, and help build what the world needs.
The complete BXP v2.0 Technical Specification is publicly available. Read it, review it, implement it. Every implementation strengthens the standard.
