EVIDENCE · LIVE

What is proven. What is not.

Every claim Coreum makes, with how far the evidence goes and where to check it yourself — on Robinhood Chain, on Bitcoin, or by recomputing the hashes. If a row says Not yet, we do not claim it.

CLAIMSTATUSEVIDENCE BOUNDARYCHECK IT

Every verdict is written into a verified contract on Robinhood Chain

Proven

Written hourly in batches, so the newest verdicts stay pending for up to an hour.

Contract source ↗Read verdictOf() ↗

Only the network's wallet can write, and a written verdict cannot be changed

Proven

Enforced by the contract code: seal() is writer-only and skips jobs already sealed.

Cores commit a hash before anyone reveals (commit–reveal)

Proven

Every commitment, verdict, reason and salt is public; recompute sha256(job | verdict | reason | salt).

Any answer page

The ledger is a SHA-256 hash chain anyone can recompute

Proven

Recomputing proves nothing was edited after the fact — not that the answers are right.

Each verdict is sealed into the ledger exactly once

Partly

Jobs #19, #35, #37, #38 and #53 were sealed twice by a race, fixed on 20 Oct 2026. Both copies stay — editing the ledger would break the chain — and the contract holds one of each.

Run the verifier

The ledger head is anchored on Robinhood Chain every hour

Proven

Each anchor is a transaction whose calldata reads coreum-anchor:v1:<block>:<hash>.

Anchor list

The ledger head is anchored on Bitcoin every day

Proven

Via OpenTimestamps; a stamp becomes a Bitcoin proof once its calendar commits (a few hours).

Anchor list (kind: ots)

Five different AI models answer every question

Proven

Llama 3.3 70B, Mistral Small 3.1, Qwen3 30B, Gemma 4 26B, GPT-OSS 20B — named on every answer.

Cores

Token Check judges a token from its on-chain facts

Partly

Facts come from GeckoTerminal and the token's owner() over RPC. A risk screen, not a code audit.

Example: $CORS

The cores are run by independent operators

Not yet

Today all six reference cores are run by Coreum: five open models on Cloudflare Workers AI and DeepSeek V3 through DeepSeek's API. Anyone can run a community core; none is online yet.

Run a core

The network knows about recent events

Not yet

Cores answer from model knowledge, with no web search; on topics newer than their training they answer UNSURE.

Example

Every verdict is correct

Not yet

Not claimed. A verdict is what independent models agree on — they can be wrong together.

REPRODUCE

Check it yourself in one command.

One file, no dependencies, Node 18+. It downloads the ledger and recomputes every hash, reads each verdict straight from the contract on Robinhood Chain, matches every anchor transaction to the ledger, and recomputes the cores' commitments from their revealed answers. It never signs or sends anything.

curl -O https://www.coreum.xyz/verify-coreum.mjs
node verify-coreum.mjs              # commit-reveal on the last 10 jobs
node verify-coreum.mjs --reveal 60  # or more

Read the script before you run it: verify-coreum.mjs. Exit code 0 means everything matched; anything else prints what did not.
