Binance Publishes New zk Proof-of-Reserves Snapshot

Binance completed a new zero-knowledge proof-of-reserves (PoR) snapshot that, per The Block (Nov. 2, 2026), lets users holding listed assets verify their balances are included. Whether the zk proof was published after a later 50–60 hour estimate is unconfirmed. U.Today's Nov. 14, 2026 page description calls it a security upgrade, but zk-SNARKs have been in Binance's PoR since 2023. The Block's headline and crypto.news both link the snapshot to recovery from a reported security incident.

What was announced

The Block reported (its URL is dated Nov. 2, 2026) that Binance finished the snapshot. Users holding BTC, ETH, USDT, BNB, SOL, USDC, XRP, USD1, RLUSD and ZEC can independently verify their balances are included. The outlet's headline ties the snapshot to work to restore assets and withdrawals after a reported hack. Only the opening of that report was reviewed.

U.Today's page description says Binance is drawing attention to a security upgrade. It says the upgrade lets users independently verify their assets are backed at a minimum 1:1 ratio. Only the page metadata was reviewed, not the article body. A Binance primary statement could not be confirmed.

The method is not new

On Feb. 10, 2023, Binance announced that its PoR system had integrated zk-SNARKs, a zero-knowledge verification method. Cointelegraph reported it as an upgrade to improve the security and transparency of reserve verification.

The 2026 item is therefore a new snapshot, not the introduction of zero-knowledge proofs. Calling it a 2026 security upgrade may overstate what is new, though Binance's own description of any technical change was not confirmed.

Incident context

crypto.news reported that Binance said it had completed coverage of assets affected by a security incident and published a new PoR snapshot. User verification was still waiting on the zk proof. Binance estimated it would take 50–60 hours to generate because of the computing workload. The report's exact date was not confirmed (the snippet says only "Nov."), so it is unclear whether that window has already passed.

The size, date and cause of the incident remain unconfirmed. This brief does not state them as fact. It is also unconfirmed whether the zk proof has since been published, and whether withdrawals were suspended or restored.

What the snapshot does and does not establish

Per The Block, the snapshot lets users confirm their own balances are included. The minimum 1:1 backing claim comes from U.Today's description only. No independent audit of Binance's reserves was found in the sources reviewed.

Market context

BNB traded at about $606.11 on Nov. 14 at 14:01 UTC, with a market cap of $79.82 billion.

Among assets in the snapshot, BTC traded at $66,670.62, ETH at $1,888.42 and USDT at $0.99917 at that time.
