Open Source Base L2 Stele v1

Cryptographic proof
of physical reality.

HolyAxiom makes every moment tamper-evident — sealed by hardware, anchored on blockchain, verified by mathematics. In a world of deepfakes and synthetic media, we build the infrastructure for truth.

"If it happened — there is proof.
If there is no proof — it didn't happen."

6 Sensors

GPS, IMU, audio ADC, optical PRNU, clock, entropy pool — all feeding the ha-chip trust boundary simultaneously.

7 AI anomaly detectors. ECDSA P-256 signature. Non-extractable hardware key. Raw sensor data never touches the app CPU.

Stele Proof

The world's first language for physical reality claims. Hardware level baked into the type system. Compiles to Solidity.

Base L2

Merkle roots anchored on-chain every 30 seconds. Verifiable by any smart contract. Permanent. Public. Forever.

We invented a new language for truth.

Stele is the world's first formal language for expressing cryptographic claims about physical reality. Hardware level is part of the type system — not a runtime check. A proof that claims L2 hardware but only provides L0 evidence is rejected at compile time.

Stele programs compile to Solidity require() statements — making your proof verifiable by any smart contract, on any chain, forever.
