What it looks like inside
Chance is the verification harness between an agent's intent and its execution. Five parts work together so that every verdict it produces is recorded as it happens, signed inside sealed hardware, and written to a public blockchain — then anyone can re-check the whole thing from their own browser, trusting no one in the middle.
How a decision flows
The agent reasons and searches the web; every step is sealed into a tamper-proof record as it happens.
A key inside the confidential enclave signs the result — proving which exact program produced it.
The signed result is written to a public blockchain: permanent, timestamped, unchangeable.
Your browser re-derives everything and checks it against the chain. Trust no one — recompute it.
What no one can fake
- ✓Every result is tamper-evident — alter one byte and it shows.
- ✓It's attributable to the exact code that produced it (sealed in hardware).
- ✓Once anchored, it's permanent and can't be quietly changed or denied.
- ✓Anyone can re-verify it independently — no trust in Chance required.
- ·The operator can run agents — but can't sign as the judge or edit a published record undetectably.
- ·The cloud host runs the program — but can't read the sealed key out of the enclave.
- ·Anyone with a link can read and re-verify a result — but can't forge or change one.
- ·The decision registry is a smart contract deployed on Base mainnet — every anchored decision is a real, public transaction.
- ·The signing key runs in a genuine AMD SEV-SNP confidential enclave on Microsoft Azure, attested in hardware on every run.
- ·The agent runs on a current frontier model with live web search.
