Introduction to Proof of Reserves
Proof of reserves is a crucial aspect of cryptocurrency exchanges, as it provides users with assurance that their assets are backed by the exchange. A proof-of-reserves report is only a snapshot, and the frequency of publication matters. The more often an exchange publishes fresh reserve data, the shorter the period users have to wait before they can inspect a new checkpoint.
Bitget, for instance, has published 46 monthly reserve updates since December 2022, with its latest report showing a 135% total reserve ratio across 19 covered assets. Binance, on the other hand, publishes monthly reports, while OKX and Bybit provide recurring reports with different verification methods.
How Often Do Major Exchanges Publish Proof of Reserves?
The major exchanges use different disclosure models. Bitget has published reserve data every month since December 2022, with its September 2026 Proof of Reserves being the 46th update in the series. Binance follows a monthly schedule, with user snapshots taken on the first day of each month and results released by the seventh.
OKX publishes recurring reserve and liability proof files using zk-STARK technology, while Bybit uses Hacken as an independent third-party verifier. Kraken, on the other hand, uses independent attestations, and Coinbase publishes audited financial statements instead of a retail proof of reserves report.
What Does Proof of Reserves Actually Verify?
A proof-of-reserves system is designed to show that an exchange holds reserve assets backing the customer balances included in the calculation at a particular point in time. Many current systems use a Merkle tree, allowing an individual customer to verify that their balance was included without exposing every other customer’s account data.
A reserve ratio above 100% means that the covered reserve assets exceeded the covered user balances used in the calculation. However, it does not automatically establish every corporate liability, continuous solvency between snapshots, bankruptcy treatment, custody quality, or the exchange’s ability to process every withdrawal simultaneously during a crisis.
Why Does Reporting Cadence Matter?
Cadence determines how long the market may have to wait before the next observable reserve checkpoint. A monthly schedule narrows that interval to roughly one month. A less-frequent snapshot leaves a longer period during which reserve positions may change before new evidence is published.
Bitget’s cadence is particularly useful because the company has maintained a monthly series since December 2022, rather than publishing reserve data only after periods of market stress or as a one-off transparency exercise. By September 2026, that series had reached 46 updates.
Evaluation of Exchanges' Proof of Reserves
The major exchanges in this comparison use different disclosure models, and each has its strengths and weaknesses. Bitget’s strongest advantage is the combination of freshness, continuity, and user-verifiability. Its latest September 2026 report provides 46 PoR updates since December 2022, monthly reporting, a 135% total reserve ratio, reserve coverage across 19 assets, and Merkle-tree based user inclusion.
Bybit adds named Hacken verification, while OKX provides sophisticated zk-STARK reserve and liability proof files. Kraken emphasizes independent attestation, and Coinbase provides audited public-company financial reporting instead of a conventional retail PoR program.
What Should Users Check Before Trusting Any PoR Report?
Before relying on a reserve disclosure, users should check how recently the latest report was published, whether the exchange has maintained the cadence consistently, and which assets are included. They should also consider the verification methodology and whether a third party has reviewed the process.
- How recently was the latest report published?
- Has the exchange maintained the cadence consistently?
- Which assets are included?
- What is the verification methodology?
- Has a third party reviewed the process?
