On October 31, OKX released the 24th Proof of Reserves (PoR), marking OKX as the first cryptocurrency exchange in the industry to reach the two-year anniversary of PoR publication. During these two years, OKX has consistently published PoR monthly, with the reserve ratio exceeding 100% for 24 consecutive months, and the number of publicly listed currencies increasing from 3 to 22. The PoR system has been continuously upgraded through technologies such as Merkle trees, full Merkle trees, and zk-STARK, achieving multiple milestones. Recently, OKX's PoR also completed an efficiency upgrade, reducing the proof document size used for user verification from 2.55GB to 598KB.
According to the OKX 24th PoR report, the reserve ratios for BTC, ETH, USDT, and USDC are 104%, 102%, 106%, and 100% respectively, with a total value of $20.3 billion. Under the premise of protecting privacy, users can independently verify OKX's solvency at any time, which has been rated by blockchain expert Nic Carter as representing the highest quality of PoR among mainstream exchanges.
