The oracle constellation

Seventeen math oracles sell verifiable computation — not trust-me APIs. Discover via Hub or MCP, pay in USDC micropayments, verify every proof yourself. Physical IoT (GAIA live relays) is a separate third class on the same Hub.

Also on the Hub — GAIA physical oracles

Live attested relays: Open-Meteo weather/AQ, UK grid carbon, USGS quakes, NOAA tides (+ sim fleet). Same discover → channel → invoke loop as the math family.

All oracles

Platon

Verifiable randomness + dynamical oracle

A 32-dimensional chaotic substrate that emits signed, auditable entropy and signals — the randomness agents need for sampling, nonces, tie-breaks, lotteries and leader election.

Chronos

Verifiable delay — proof of elapsed sequential time

Proves that real, non-parallelizable time has passed. Fair ordering, anti-MEV, timeouts — and an unbiasable randomness beacon when wrapped over Platon.

Lattice

Low-discrepancy (quasi-random) sequences

When agents need EVEN coverage, not random clumps: quasi-Monte-Carlo integration, sampling, coverage testing, optimization seeding.

Murmuration

Robust consensus aggregation

Turns a noisy crowd of agent estimates into one breakdown-resistant number — outliers can't move it. Price feeds, sortition, federated decisions.

Lumen

Reputation & trust scores

Who should an agent trust to invoke? Sybil-resistant reputation over an interaction graph — the basic need of any agent economy.

Colony

Optimization with a quality certificate

Agents offload NP-hard sub-problems (routing, assignment, scheduling) and get a near-optimal answer WITH a proof of how good it is.

Turing

Blue-noise structured sampling

Even, organic, never-clumped point sets — superior to white noise for sampling, dithering, stippling and procedural masks.

Percola

Network-resilience threshold

When does the whole trust graph fall apart? Computes the critical attack fraction f_c, collapse curve, susceptibility peak, and keystone nodes — a global phase transition no per-node score can express.

Fermat

Least-time routing with a dual certificate

Provably optimal capability composition over a weighted service graph — returns the least-time path plus eikonal potentials T(v) any client can verify in O(E) without re-running search.

Ablation

Systemic cascade-risk (SOC sandpile)

The tail risk of a dependency network: drives stress through a sandpile, fits the avalanche power-law τ, VaR/CVaR tails, and the trigger nodes that ignite market-wide cascades.

Landauer

Thermodynamic compute-cost audit

The physical price of irreversible computation: counts logically erased bits, derives the kT·ln2 energy floor in joules, Bennett's reversible bound, and thermodynamic efficiency.

Sortes

True ECVRF — ungrindable verifiable randomness

Draws lots you can verify. For a fixed (key, input) there is exactly ONE valid output — the oracle cannot grind or bias it, and anyone can verify the draw offline from an 80-byte proof. Lotteries, sortition, leader election, fair nonces.

Gauss

Gaussian-Process posterior + active-learning suggestions

Turns sparse, noisy observations into a calibrated posterior over functions — a mean and an honest uncertainty everywhere — and names the single best next point to sample. The principled replacement for hand-rolled UCB / bandit exploration: the uncertainty is computed, not tuned.

Aestus

Time-lock puzzles — seal now, opens later

Seals data so NOBODY can open it before ~T sequential squarings of wall-clock have elapsed — then ANYONE can, with no trapdoor holder. Sealed-bid auctions, dead-man switches, timed disclosure, fair coordinated reveals. Where Chronos proves the past elapsed, Aestus locks the future.

Betti

Topological shape — persistent homology

What SHAPE does the data have? Builds a Vietoris-Rips filtration and reads off Betti numbers b0 (clusters), b1 (loops), b2 (voids) across scale, plus a bottleneck-distance drift alarm — structure no scalar summary can express.

Kantor

Exact optimal transport with a dual certificate

How cheaply can one distribution become another — and is it provably the cheapest? Solves the exact Wasserstein / earth-mover problem and returns the transport plan plus Kantorovich potentials any client can verify in O(m·n) without re-solving.

Fourier

Graph-spectral analysis — Laplacian spectrum & Fiedler value

The Fourier transform on a graph. Reads the algebraic connectivity λ₂ (how close a network is to splitting), the Fiedler vector and its spectral bisection, and a spectral embedding — the global structure no per-node metric captures.
