Binance says it completed a zero-knowledge Proof of Reserves for Oct. 31 snapshot, CryptoBriefing reports (unconfirmed primary artifacts)

Opening — what was reported and the immediate caveat

CryptoBriefing reports that Binance "says it has finished a zero-knowledge proof for its Proof of Reserves snapshot taken on October 31." This snapshot is reported to cover the instant 00:00 UTC on October 31, 2026.

The reporting attributes technical details to Binance — specifically that the proof uses a zk‑SNARK implemented on a Merkle‑tree structure and that an open‑source verification tool is available on Binance's Proof of Reserves website and GitHub.

The supplied reporting reproduces reserve ratios for the covered tokens (examples: Bitcoin at 100.04% and BNB at 101.30%).

Important caveat: the primary cryptographic proof files, the actual verification tool URLs and independent third‑party audits were not supplied in the materials provided to this brief; those artifacts therefore remain unverified here.

Essential facts (reported by CryptoBriefing, on record)

Snapshot timestamp: 00:00 UTC on October 31, 2026 (reported).

Scope: proof reportedly covers ten tokens — BTC, ETH, USDT, BNB, SOL, USDC, XRP, USD1, RLUSD, and ZEC (reported).

Technical approach: reported use of a zk‑SNARK over a Merkle‑tree structure to prove total liabilities were covered without publishing individual balances (reported).

Verification claim: CryptoBriefing reports Binance says an open‑source verification tool is available on the exchange’s Proof of Reserves website and GitHub (reported).

Reserve ratios: CryptoBriefing reproduces Binance’s reported reserve ratios for the covered tokens (examples cited in the report include Bitcoin at 100.04% and BNB at 101.30%).

Follow-up snapshot: CryptoBriefing reports Binance planned another Proof of Reserves snapshot on November 4, 2026 to include additional tokens (reported).

Context — why this matters now

The report notes the Oct. 29–30 hot‑wallet drain (reported at roughly $6.3 billion) as recent context; CryptoBriefing also reports Binance said it had recovered about 95% of affected assets as of Nov. 2, 2026, though the primary Binance update was not supplied in the provided materials.

A zero‑knowledge Proof of Reserves, as described, is intended to let users and observers verify total liabilities are covered at a specific moment without exposing individual balances — a difference from simple public balance disclosures. CryptoBriefing characterises this approach as stronger than simpler PoR methods because it keeps account privacy intact while enabling aggregate verification (reported).

Confirmed developments from the source material

Binance reported completion of a zero‑knowledge proof for the Oct. 31 snapshot, per CryptoBriefing’s on‑record reporting.

The proof is reported to cover ten named tokens and to include reported reserve ratios that CryptoBriefing reproduces.

CryptoBriefing reports Binance provided or will provide verification tooling (open‑source) on its Proof of Reserves website and on GitHub, enabling independent checks according to the report.

Binance reportedly scheduled an additional Proof of Reserves snapshot for Nov. 4, 2026 to broaden token coverage.

Limits and unknowns — what the report does not prove

The reported proof is explicitly a snapshot: CryptoBriefing notes it proves coverage at the single instant 00:00 UTC on Oct. 31, 2026 and does not demonstrate backing at times before or after that instant (reported).

Primary cryptographic proof artifacts (the proof files), the verification tool URLs, and any independent third‑party cryptographic audits are not included in the supplied materials and therefore remain unverified here.

CryptoBriefing flags a scope limitation: none of the ten tokens in the proof were among the less‑liquid tokens Binance said made up the remaining reported shortfall (reported). This means the proof’s token set may not cover tokens cited elsewhere as part of a shortfall, per the report.

Analysis — interpretation and careful inference

What this means for users

If implemented as described, a zk‑SNARK over a Merkle‑tree can allow an exchange to demonstrate aggregated solvency or that total liabilities are covered at a snapshot moment while keeping individual account balances private. CryptoBriefing reports Binance claims that capability.

Because the supplied reporting reproduces reserve ratios and cites an open‑source verification tool, readers can expect Binance intends for independent verification. However, without the primary proof files, the tool’s URLs or an independent audit included in the supplied materials, independent verification cannot be completed from the provided source alone.

The snapshot nature and reported token scope limit what this proof can show: it does not demonstrate continuous solvency, nor does it cover tokens outside the reported ten. The Oct. 29–30 hot‑wallet drain and reported partial recovery remain relevant context but are not proven by this single snapshot claim.

• Users may be able to verify their inclusion and the aggregate coverage if Binance provides the advertised open‑source tool and the cryptographic artifacts.
• Even a verified snapshot does not prove ongoing backing at moments after Oct. 31.
• Tokens not included in the reported ten remain outside this proof’s scope, per the source.

Useful reader questions and current status

What exactly did Binance publish? (Primary proof files, the proof’s public parameters and the verifier tool URL are not supplied in the CryptoBriefing materials.)

How can I verify my account was counted? (CryptoBriefing reports Binance provided an open‑source verification tool on its Proof of Reserves site and GitHub; the tool’s links and proof artifacts were not supplied here.)

Does this snapshot mean funds are safe today? (A single snapshot only demonstrates coverage at the reported instant, not continuous backing.)

Will upcoming snapshots expand coverage? (CryptoBriefing reports Binance scheduled another snapshot for Nov. 4, 2026 to include additional tokens.)

• Current status: Reported completion of a zk PoR for the Oct. 31 snapshot (CryptoBriefing).
• Unresolved: primary proof artifacts, verification URLs and independent third‑party audits were not supplied in the provided materials.

Closing — what to watch next

Watch for publication of the cryptographic proof artifacts, the verification tool URLs on Binance’s Proof of Reserves website and GitHub, and any independent third‑party audits or community verifications.

CryptoBriefing reports a Nov. 4, 2026 follow‑up snapshot that Binance planned to use to include additional tokens; that follow‑up and any supply of primary artifacts will be important to validate the on‑record claims reproduced here.
