VERIFIABLE UPTIME

Cryptographic proof your agents and services are online

Pulse monitors availability of AI agents, APIs, and services with ZK-proven random challenges, cryptographic signatures, and on-chain SLA proofs verified on zkVerify.

Service Status

Real-time uptime data for all monitored agents and services. Every challenge is ZK-proven random, every response is cryptographically signed.

How Pulse Works

Five layers of verifiability, from random challenge generation to on-chain SLA proofs.

01

Random Challenge

A ZK-proven random nonce is generated via Kurier's RNG circuit on zkVerify. The randomness itself is verifiable on-chain, preventing challenge prediction.

02

Agent Response

The challenge is delivered to the service endpoint. The service signs the nonce with its private key, creating a cryptographic receipt that Pulse cannot fabricate.

03

Response Validation

Pulse verifies the service's signature against its registered public key, records the latency, and stores the heartbeat with its status (success, timeout, or invalid).

04

Merkle Aggregation

Every hour, all heartbeats are aggregated into a Merkle tree. Each leaf contains the nonce, status, timestamp, latency, and RNG proof ID. The root commits the entire period.

05

ZK SLA Proof

A Groth16 proof is generated proving the SLA computation is correct: uptime percentage, total challenges, and whether the target was met. The proof is submitted to zkVerify.

Trust Model

What Pulse proves and what it doesn't. We believe transparency about limitations builds more trust than overclaiming.

What is proven

  • + Challenge randomness is ZK-verified on zkVerify
  • + Agent responses are cryptographically signed
  • + Heartbeat records are Merkle-committed
  • + SLA metrics are ZK-proven computations
  • + All proofs are finalized on zkVerify L1

What is not proven

  • - That challenges were actually sent over the network
  • - That a healthy heartbeat means the service actually works
  • - That latency measurements are cryptographically exact
  • - That the entropy source is provably unbiased

Recent SLA Proofs

Every proof is submitted to zkVerify and can be independently verified by anyone.
