Boundless Halts ZK Proving, Redirects ZKC Into AI Credit Payouts

The Boundless Foundation will stop accepting new zero-knowledge proof requests on November 5, 2026, and will replace ZKC's staking rewards with metered access to open-weight AI models starting January 2, 2027, according to a November 3 Foundation post. The change retires the proving product outright and rewrites the token's utility around what the Foundation calls tokenized AI inference.

The mechanics are contained in the existing staking contract. Holders do not need to deposit anything new. They keep ZKC staked, sign a message linking their wallet to a Boundless AI account, and receive a pro-rata share of a shared credit pool every two days. Staked ZKC is not spent when credits are drawn down.

How big is the credit pool?

The initial pool is roughly $1,000 of AI credits per allocation window. A wallet holding 1% of total staked ZKC would receive about 1% of that pool, or around $10 per two-day window. Credits expire when the next window opens, and the Foundation says they are nontransferable and carry no cash value. Pool size, refresh timing, and the model menu remain project parameters the Foundation can adjust for capacity and cost.

The supply schedule flips alongside the payout schedule. Proving rewards stop first. Staking rewards run through one final epoch ending January 1, 2027, after which the Foundation says no new ZKC will be minted. The circulating total becomes fixed at the last verified on-chain amount, and AI credits begin the following day. The structure keeps stakers paid without expanding the token float.

What happens on each date?

The Foundation's shutdown calendar lists four concrete deadlines:

• November 5, 2026: New proof requests end. Outstanding proving rewards must be claimed before this cutoff.
• November 30, 2026: The Explorer interface goes offline. Staking moves to a standalone UI, with instructions published beforehand. The existing contract's 30-day withdrawal period remains in force.
• January 1, 2027: The final staking-reward epoch ends; minting of new ZKC stops once settlement clears.
• January 2, 2027: Tokenized inference launches for eligible stakers on Boundless AI.

An earlier Foundation brief had already announced the November 5 proving pause and the Explorer retirement. The November 3 post adds the credit math, the fixed-supply commitment, and the January 2027 launch date. The Foundation says the protocol's source code remains public even while proving operations sit idle.

Why does the split of responsibilities matter?

The on-chain role here is narrow. The contract accounts for who is staked and in what proportion. Boundless AI handles delivery: open-weight models served through its platform, its API, and integrations including Vercel's AI Gateway. Linking a wallet does not verify that a model output was correct, safe, or useful. It proves only that the Foundation accepted a stake-linked claim on a credit pool.

The economics constrain the pitch. Roughly $1,000 every two days, split across all eligible stake, functions as a small shared faucet rather than a personal compute stipend. The credits hold value only as long as Boundless AI keeps serving models, an operating commitment rather than a cryptographic guarantee. Demand that relied on Boundless operating as a live prover network loses that path on November 5.

Who else is converting stake into compute?

Most crypto staking still pays out more of the same token. Boundless is taking the opposite bet: lock capital, receive inference that users would otherwise buy from a cloud bill. The model sits alongside other AI-blockchain experiments that turn staked assets into compute claims rather than token yield, with 0G's route from staked assets into AI compute credits as one parallel.

Open questions remain in the Foundation's own terms. Eligibility rules, the list of supported models, and the exact final supply figure are still being filled in. ZKC holders who wanted proof rewards now hold a claim on AI access instead, under terms the Foundation has not finished publishing.

The practical deadline is November 5, 2026: proving rewards unclaimed by that date disappear with the product. Whether a share of a small, expiring credit pool makes an "AI Access Coin" mean usable model time rather than a rebranded stake becomes testable on January 2, 2027.
