For as long as human beings have looked at the sky, we have wondered what looks back. Pilots in every era of aviation have reported encounters with aerial phenomena their instruments could measure but their training could not explain. The United States military has officially confirmed the existence of Unidentified Aerial Phenomena — objects demonstrating flight characteristics beyond the known capabilities of any human-built aircraft.
Congress has held hearings. Former military and intelligence officials have testified under oath. The question is no longer whether something unexplained is happening in our skies. The question is what — and the only way to answer it is with rigorous, independent, tamper-proof data collected at scale.
That data does not yet exist. Governments classify what they collect. Individual sightings are dismissed as anecdotal. SENTINEL exists to change that — permanently, publicly, and in the hands of the people.
SENTINEL is a scientific instrument, not a cryptocurrency project. It scans our skies continuously, documents every anomalous detection — whether UAP or unidentified drone — and stores that data on a blockchain-verified, decentralized network that no government, corporation, or even its own founder can suppress or alter.
"The sky has always had witnesses. For the first time, those witnesses have a voice that cannot be silenced."
SENTINEL is not only about answering ancient questions. It is about protecting America right now. The skies above our homes, military bases, power plants, and airports are increasingly contested — and the public has no independent system for monitoring what moves through them.
Unmanned aerial vehicles operated by foreign state actors have been documented near sensitive US military installations, nuclear facilities, and critical infrastructure. These incursions represent a direct national security threat with no adequate public-facing response system.
Drone warfare is not the future — it is the present. Conflicts worldwide have demonstrated that swarms of small, cheap, commercially available drones can overwhelm traditional defenses. The United States needs a distributed, citizen-accessible early warning layer now, before the threat escalates further.
Military radar infrastructure is classified, inaccessible to the public, and not designed for distributed low-altitude monitoring. Law enforcement lacks the tools. The public has no visibility. SENTINEL fills this gap with a citizen-powered network that covers the ground-level airspace no existing system adequately monitors.
Imagine thousands of SENTINEL nodes — in homes, farms, and neighborhoods across the country — forming a continuous, citizen-operated radar net. Every unidentified drone, every anomalous aerial object, permanently recorded and publicly accessible. No single point of control. No suppression possible.
SENTINEL scans our skies and documents everything — UAPs that defy explanation and unidentified drones that threaten our security alike. Both are recorded permanently on the blockchain. Both are accessible to citizens, researchers, journalists, and government agencies. The data belongs to the American people.
SENTINEL was built to answer humanity's oldest question and protect America's immediate security. These missions are not in conflict — they are served by the same distributed radar network, the same blockchain-verified data archive, and the same commitment to open, citizen-accessible information.
Continuously scanning for and documenting Unidentified Aerial Phenomena — objects that cannot be explained by known aviation. Every anomalous detection is cryptographically signed, blockchain-timestamped, and permanently archived. The scientific record that the UAP question has always needed, finally being built by the people.
Identifying, documenting, and archiving unidentified drone activity across American airspace. Foreign adversarial drones, commercially operated drones without flight plans, and any unmanned aerial vehicle that cannot be correlated with known operators — all recorded, all permanent, all public. A citizen early-warning system for the drone age.
"Not even the founder of SENTINEL will be able to keep this information away from the people. That is the entire point." — Damon Mayo, Founder
All detection data — whether UAP or unidentified drone — is stored using the same architecture: raw data on a decentralized storage network spanning thousands of hard drives worldwide, with cryptographic proof of every record written permanently to the blockchain. No single authority controls the storage. No single authority can remove a record.
SENTINEL operates as four interconnected layers — from the radar sensor at your home, to an alert on your phone, to two parallel blockchain networks, to open access for citizen scientists and security researchers worldwide.
Every aerial object detected — commercial aircraft, drone, bird, or unknown — is automatically classified. ADS-B integration filters routine aviation in real time, leaving anomalous and unidentified objects for investigation.
Matches ADS-B transponder data for commercial, private, or military aviation
Profile consistent with known drone, bird, or weather balloon — documented and archived
Speed, maneuver, or profile outside the capability envelope of any known aircraft or drone
No correlation with any known aerial object — UAP or otherwise — across all sensor data
Every SENTINEL node starts with a Core radar module and expands with optional sensors. More sensors means richer detection packages — whether you are documenting a UAP, tracking an unidentified drone, or both simultaneously.
A full-stack node produces a complete evidence package for every detection: radar track, acoustic signature, optical image, thermal profile, RF emissions, and environmental readings — all cryptographically signed and blockchain-archived.
Continuous mmWave radar monitoring with cryptographic data submission. The foundation of every SENTINEL node.
BirdNET AI automatically identifies birds. Engine classification distinguishes drones from aircraft. Infrasound detection captures low-frequency anomalies.
Radar-triggered camera activates only on T2+ detections. Captures UAPs and unidentified drones. Every image cryptographically linked to its radar event.
FLIR infrared imaging detects heat signatures in total darkness. Distinguishes drone thermal profiles from birds, aircraft, and unknown objects.
Software Defined Radio monitors electromagnetic emissions. Identifies drone control frequencies. Flags objects emitting unknown or no RF signals.
Monitors magnetic field disturbances, radiation anomalies, and EMF fluctuations — environmental signatures historically associated with both UAPs and advanced drone technology.
SENTINEL was built from scratch by a small team driven by one conviction: the most important scientific question in human history — and the most urgent national security challenge of our era — both deserve a serious, independent, citizen-powered answer.
Inventor and entrepreneur who conceived the SENTINEL concept and brought it from idea to blockchain-verified reality. Damon leads SENTINEL's vision, strategy, legal structure, and community — driven by the belief that the sky belongs to everyone and its secrets should be kept by no one.
