OKX Introduces zk-STARK Technology to Proof of Reserves, Monthly Snapshot Shows USD10.4 bln in BTC, ETH and USDT

• 18 additional cryptocurrencies included in OKX Proof of Reserves, available to be verified using trustless tools

HONG KONG SAR, 28 APRIL, 2023 - OKX, the world’s second-largest crypto exchange by trading volume and a leading Web3 technology company, today announced the biggest upgrade to its Proof of Reserves (PoR) yet, introducing zk-STARK zero-knowledge technology which allows users to independently verify exchange solvency and confirm their assets are backed by OKX reserves.

The latest PoR report showed USD10.4 billion in Bitcoin, Ethereum and USDT, a 39% increase since January 2023.

Zero-Knowledge Scalable Transparent Argument of Knowledge (zk-STARK) is a secure cryptographic method that verifies the accuracy and authenticity of OKX's PoR while upholding user privacy - no account balances are visible to other parties.

Current OKX reserve ratios:

• BTC: 103%
• ETH: 103%
• USDT: 103%

For the first time, 18 additional crypto assets are available for the public to verify, bringing the total to 21.

The additional assets covered are: USDC, XRP, DOGE, SOL, OKB, APT, DASH, DOT, ELF, EOS, ETC, FIL, LINK, OKT, PEOPLE, TON, TRX and UNI.

Lennix Lai, Chief Commercial Officer at OKX, said: "Proof of Reserves is an indispensable way to demonstrate transparency and guarantee solvency, and builds user confidence and trust in the industry as a whole. OKX is committed to leading the crypto space when it comes to empowering users to verify reserves and liabilities in real time using trustless 'future tools' like Proof of Reserves."

OKX PoR has raised the bar for transparency in the industry, having published tens of thousands of addresses for its Merkle tree program. OKX is one of the only major platforms to release monthly PoR.

As part of its commitment to transparency, OKX will continue to publish PoR on a monthly basis.
