Binance Publishes New Proof-of-Reserves Snapshot Following October Attack

TL;DR: Binance said on November 2 that it had completed a zero-knowledge proof-of-reserves procedure for a snapshot taken October 31, following the exchange’s late-October security incident. Proof of reserves should not be described as a full financial audit, a guarantee against losses or evidence that all stolen assets have been returned.

In the aftermath of a major exploit, balance verification and service recovery are parallel tasks. Reserve attestations may restore visibility, while withdrawal readbacks show that the platform can operate. Neither should substitute for a full account of the breach. Reading the three separately makes it harder for one reassuring number to obscure unresolved questions.

Binance said on November 2 that it had completed a zero-knowledge proof-of-reserves procedure for a snapshot taken October 31, following the exchange’s late-October security incident. Its announcement listed ten major cryptoassets, including Bitcoin, Ether, USDT, BNB, Solana, USDC, XRP and several dollar tokens. The company said the affected asset replenishment programme had reached approximately 95% at the time of the update. The dated original disclosure is the starting point for the figures and product scope discussed here.

A proof-of-reserves calculation tests whether a set of exchange-controlled assets can support the included customer balances under the method and date specified. Zero-knowledge techniques can help demonstrate a relationship without exposing every account balance. That is useful, but it does not automatically assess unrelated corporate liabilities, future cash flows, operational security or the completeness of every entity in a corporate group.

Publishing a new snapshot gives customers a concrete checkpoint rather than asking them to accept an undated reassurance. The advantage is comparability over time if disclosures remain consistent and complete. Yet a positive proof on October 31 cannot certify a November 3 withdrawal or prevent another attack. The most meaningful assessment combines reserve information with functioning services, incident disclosure and independent scrutiny.

A crypto incident produces several separate timelines: containment, investigation, recovery and a return to reliable service. Those phases can overlap without finishing together. A traced wallet is not automatically frozen; a frozen balance is not automatically returned; and a reopened withdrawal route is not a completed security audit. Keeping those differences visible helps readers judge progress more accurately.

For additional perspective, it is worth reading our existing reporting on Binance’s earlier staged withdrawal restart and Bitcoin payment infrastructure and node software context. Those background reports help separate established facts from a new, still-developing announcement.

Proof of reserves should not be described as a full financial audit, a guarantee against losses or evidence that all stolen assets have been returned. The company’s 95% replenishment claim refers to affected asset coverage, not an identical ratio for every token. Liquidity and availability can differ by asset even when an aggregate recovery figure appears strong.

Operational controls matter most when a business is under stress. Security announcements should identify the system affected, the customers who can act, the evidence supporting any recovery number and what remains uncertain. Clear scope protects users from false reassurance and from unnecessary panic. It also provides a sensible basis for follow-up accountability.

Binance said another snapshot would follow on November 4 and that the related proof process could take roughly 40 to 50 hours. The important next step is to inspect the published scope, proof methodology and any changes in customer liabilities. Separate withdrawal updates will determine whether the reserves shown on paper translate into reliable customer access.
