Binance says reserve proof takes 40–50 hours: what users can check while waiting

7 min

The short answer

Binance says its full cryptographic reserve proof takes approximately 40 to 50 hours to generate, according to Cointelegraph's October 31 report. The exchange has published a new reserve snapshot while the proof is being prepared. For a customer waiting to move funds, that leaves a practical distinction: a reserve update, a completed proof and a completed personal withdrawal answer different questions. Cointelegraph's reporting on the reserve update.

The reported computation time is the new point examined here. Our earlier report on Binance’s 90% replenishment examined the remaining token shortfall. This analysis asks which evidence a customer should look for during the gap between an exchange's statement and the publication of material that can be checked. Neither the reported duration nor a reserve percentage supplies an account-specific withdrawal result.

Why a 40–50-hour estimate needs a starting point

Cointelegraph reports Binance's explanation that the computational workload makes the full zero-knowledge proof take about 40 to 50 hours to generate. It also reports that Binance had published a new reserves snapshot. Those are two distinct pieces of information: a snapshot has been made available, and further proof material is still being generated.

The report does not establish the exact moment at which that generation started. A customer therefore cannot turn the range into a reliable completion deadline by adding it to the time they first saw the headline. The time a news page was published, the time a social post appeared and the start of the underlying computation need not be identical. We have no verified start timestamp from these reports with which to calculate the finish.

A useful next update would identify the snapshot's observation time and say whether the proof corresponds to that same snapshot. That is our evidence request, rather than a description of fields we have verified on Binance's current page. Readers should preserve the date attached to each document they consult instead of treating all documents visible on the same day as one record.

The reported estimate also gives no basis for judging whether an individual account's withdrawal will be processed before or after proof publication. CNBC describes reopening as a separate milestone subject to security checks and final confirmation. There is no confirmed sequence in the opened reports that puts every user's transaction behind the end of the proof calculation. CNBC's report on coverage and the withdrawal conditions.

A coverage statement leaves questions about the supporting record

Both reports say Binance had replenished or covered about 90% of the stolen token assets. CNBC explicitly distinguishes that backing from recovery of assets from the attacker. Cointelegraph reports that less-liquid tokens make up the remaining shortfall and are being purchased through market and over-the-counter transactions.

Those statements describe the exchange's reported replenishment progress. The proof question concerns the support available for assessing that account. Cointelegraph says CertiK had told it on Friday that more information was needed to verify Binance's claimed $5 billion in replacement cryptocurrencies. The article then describes the subsequent snapshot and the proof still being generated. CertiK's earlier request should retain its date; it cannot be presented as a review of a later completed proof.

For a customer, the most useful way to read the next publication is to ask what specific assertion it supports. Does it address a particular asset balance? Which observation date does it use? Does it explain how the stated coverage relates to customer obligations? These questions are the framework of our analysis. The opened reports do not contain enough material for us to answer them on behalf of an independent verifier.

A broad coverage percentage also needs to remain attached to the subject it measures. The 90% figure concerns the reported replenishment of stolen token assets. It is not a figure for the proportion of personal withdrawal requests completed, the probability of receiving a transfer or the proportion of stolen funds recovered. Substituting any of those meanings would change the claim.

The top-ten claim is asset-specific

CNBC lists the assets Binance says are fully backed: BTC, ETH, USDT, BNB, SOL, USDC, XRP, USD1, RLUSD and ZEC. It reports Binance's explanation that the outstanding tokens outside that group are less liquid and take longer to source in the required amounts. Cointelegraph describes bitcoin, ether and eight other assets as fully backed in Binance's update.

An account holder can use that reported list to formulate a precise question about an asset they hold. They should not assume that a statement about BTC also describes an unrelated token, or that the same update verifies the status of every network used to transfer an asset. Neither report supplies an account-by-account or network-by-network processing record.

This is particularly relevant when an account contains several assets. Keep each balance and each pending transfer identifiable in your own records. A general statement about reserves will not tell you whether a specific request has a transaction reference, which destination it uses or whether the receiving wallet has recorded the transfer. Those are the details to ask about when the service provides an account-specific answer.

The less-liquid token explanation also remains an attributed explanation. The reports do not provide an itemized list of every remaining purchase, its execution price or its completion time. We cannot calculate a completion schedule for those assets from the aggregate percentage, and a proof-generation estimate does not fill that gap.

Replacement funding and frozen funds require separate accounting

Cointelegraph reports that Binance is using its corporate treasury, part of SAFU and a portion of its futures insurance fund to replace stolen assets. CNBC identifies the same funding sources. Cointelegraph says the spokesperson did not specify how much each contributed or disclose the minimum required insurance-fund balance.

The reporting also separates replacement assets from tokens frozen after the incident. Cointelegraph describes roughly $3 billion frozen by industry partners including Tether and Circle, while saying those funds are separate from Binance's replacement of stolen tokens. We do not add that rounded freeze figure to the replenishment percentage or treat it as money returned to customers.

That separation matters when evaluating the next reserve publication. A statement about a funding source explains where replacement resources reportedly came from. A statement about frozen assets describes a different category. An account-specific transfer receipt describes a customer's transaction. A future reconciliation would be more useful if it connected the relevant categories explicitly, without requiring readers to infer that two headline totals can be combined.

We have not reconstructed that reconciliation. The available reports support the attributed funding explanation and the existence of a reported proof-generation delay. They do not establish the contribution from each fund, a final recovered amount or an independently verified final balance sheet for this incident.

Reopening is a service milestone with its own evidence

CNBC reports that Binance was aiming to resume withdrawals on Sunday, November 1, subject to security checks and final confirmation. As of this analysis prepared on November 1 SGT, the cited report is evidence of the plan. It does not establish that withdrawals have reopened for every account or asset.

The customer task should follow the service state that can actually be observed. For an existing request, preserve its reference, requested asset, amount and destination. If the account supplies a blockchain transaction identifier, compare that identifier with the receiving wallet's record. A new public statement can then be assessed alongside the request instead of replacing its history.

If a request remains pending, ask support about that request and keep the reply with the original reference. In the support message, copy the request identifier, asset, amount and destination from your saved record; add the transaction identifier if one has been supplied, then ask which status applies to that exact request.

Avoid compensation links or unsolicited messages asking you to connect a wallet, supply a recovery phrase or send funds to release a payment. Use the service through the route you already use and check its own status information. Nothing in the opened reports establishes a separate compensation website or a claim procedure requiring a payment.

What the next proof update should let a reader assess

For this story, the unresolved point is the eventual publication and assessment of the full proof. Cointelegraph's quoted estimate explains the reported waiting period. It does not supply a completed independent examination. We have not reviewed a finished proof or established a clock start for the 40-to-50-hour calculation.

Our next checks would be whether new proof material has actually appeared, what date and assets it covers, and whether an identified reviewer has examined that exact material. Keep any review tied to its scope and date. A statement asking for more information before a release cannot settle the contents of material published later.

For a personal withdrawal, keep following the transaction record separately. The evidence needed to assess an exchange's reserve representation and the evidence needed to confirm receipt of your own transfer overlap only when the connection is shown. The next useful account update is a status or transaction reference that can be matched to your existing request.
