Korean Crypto Exchanges Struggle Despite Market Recovery

OKX maintains robust asset reserves with 103% BTC backingSeychelles-incorporated cryptocurrency exchange OKX has recently released its 12th asset reserve certificate, with its latest report revealing that the company maintains reserves of 103% for its top coins, which include Bitcoin (BTC), Ethereum (ETH), Ripple (XRP), Tether (USDT) and USD Coin (USDC). The measure is meant to reassure users that their funds are well-backed and, in fact, more than covered by the exchange’s reserves.Photo by rc.xyz NFT gallery on UnsplashBitcoin, Ether reserve surplusesOKX provided details on its latest asset reserve status via a blog post published to its website on Monday. Alongside providing the relevant asset reserve data, the exchange celebrated its first complete year of having utilized a proof-of-reserve-based system.For BTC, OKX holds a substantial reserve of 140,484 BTC, effectively exceeding the 136,227 BTC held in user accounts. Similarly, ETH reserves stand at 1.46 million ETH, providing a surplus over the 1.42 million ETH owed to OKX users.The exchange also demonstrated its considerable holdings in stablecoins, with over $5 billion in USDT reserves and over $327 million in USDC reserves. In an interview with CoinDesk recently, OKX Chief Marketing Officer (CMO) Haider Rafique, referred to the need to provide a mechanism to reassure platform users. He stated:“Customers often express concerns in person about centralized exchanges, highlighting issues with security, solvency and downtimes, even if they don’t always voice these concerns digitally.”Use of zero-knowledge technologyIn April, OKX upgraded its proof of reserve system, opting for the use of zero-knowledge scalable transparent argument of knowledge (zk-STARK) technology. This approach allows OKX platform users to independently verify exchange solvency, confirming their assets are backed by OKX reserves. A zero-knowledge proof demonstrates the truth of a statement without sharing the statement’s contents. Therefore, no account balances are made public to other service users, maintaining user privacy.Regular transparency is now crucial for exchanges like OKX, as it aims to provide users with the certainty that their funds are genuinely available for withdrawal at any given time. After the FTX insolvency incident, verifiable proof of reserves has become paramount in reassuring users about the safety of their investments.Trend towards improved standardsIn the wake of several high-profile crypto platform failures in 2022, many exchanges are making greater efforts towards reassuring users that their funds are safe and accounted for. This has given rise to the popularity of proof of reserve systems.On that basis, OKX hasn’t been alone in implementing a proof of reserves-based system. In July another Seychelles-incorporated crypto platform, Bitget, announced that it could demonstrate the debt-free status of its business through its proof of reserves system.Nic Carter, Partner at crypto venture capital and private equity firm Castle Island Ventures, has carried out some research into the various proof of reserve systems employed by a number of global crypto platforms. While accepting that the approach is not foolproof, Carter maintains that it’s still a move in the right direction. “The way PoR works is, if enough exchanges do it, the few exchanges that don’t do it end up sticking out like a sore thumb,” he states.

Flybit Achieves Top Score in FIU’s Anti-Money Laundering AssessmentSouth Korean virtual asset exchange Flybit said Monday that it has received the highest rating in the comprehensive anti-money laundering (AML) evaluation conducted annually by the Financial Intelligence Unit (FIU) under the Financial Services Commission for all financial companies in Korea.Photo by REDioACTIVE on PixabayRanking among top-performing financial institutionsThe comprehensive AML evaluation is aimed at facilitating the optimal establishment and implementation of strong AML systems. It is operated under a control system where financial authorities assess and oversee a given company’s AML risk management, and the company receives verification on the adequacy of its risk management levels.In this year’s evaluation, Flybit achieved a score of 89.70, scoring in the highest ranks among all financial institutions, including virtual asset service providers (VASPs). This places Flybit among the upper echelons of financial companies that received an “Excellent” rating, which make up only 15% of all evaluated firms.Robust and varied effortsThe exchange explained that it has taken a risk-based approach (RBA) to control and manage its AML risk factors that were found in the results from the FLYBIT Enterprise-Wide AML Risk Assessment (FARA) — an AML risk assessment model developed in-house — and the FIU’s semi-annual AML system compliance evaluation, where FLYBIT was deemed as a “self-monitoring” company.Notably, Flybit operates customized AML education programs for different ranks and job roles within its corporation, which leverages both external and internal resources, including the Korea Banking Institute. It also conducts over 40 hours of advanced-level training — three times longer than the FIU recommendation — for employees directly involved in AML-related tasks.“The basis for this [evaluation] result was the active interest and support of the management, as well as the operation of a specialized AML control system for VASPs,” said Seol Ki-hwan, a compliance officer in charge of AML reporting at Flybit. “In the future, we will continue our efforts, not only in AML compliance but also in fulfilling our responsibilities and roles as a model VASP.”

Safeheron, a Singapore-based provider of digital asset self-custody solutions for institutions, has released the world’s first open-sourced trusted execution environment (TEE) related to Intel Software Guard Extensions (SGX).  The Intel SGX is a hardware-based security technology integrated within some Intel processors. It enables application developers to run application code within a secure isolated environment, while preventing access to that code or modification of it by other applications or by the operating system running on that hardware.Photo by Shubham Dhage on UnsplashAddressing Web3 security & scalability challengesThe Intel SGX enables a TEE, creating a black box for computation. In a blog post published by Safeheron on May 6, the company claimed that its open-source framework “addresses fundamental security and scalability challenges within blockchain and Web3 ecosystems, offering broad potential for deployment across critical scenarios.” The company asserted that the enabling of off-chain TEEs as achieved by its framework, provides for robust blockchain layer-2 scaling, together with privacy-preserving computation. In this way, layer-1 blockchain load can be minimized while enhancing network throughput and verifiability. Safeheron further claimed that this all paves the way for the evolution of a trusted “second execution layer” for decentralized applications. Overcoming Intel SGX complexitySafeheron developed the TEE framework using C++, a high-level object-oriented programming language. The firm open-sourced the SGX framework due to the significant challenges that developing with Intel SGX poses, arising from its complexity and its engineering overhead. On X, the company claimed that the new framework reduces SGX TEE development complexity, enabling developers to build applications securely for blockchain, cloud security and privacy computing. The framework optimizes advanced cryptographic support, enhanced testing capabilities, high-level API design and secure and encrypted file input and output. Moving beyond closed and opaque systemsSafeheron added that it open-sourced the framework as it had seen concern expressed within the Web3 sector regarding the development of closed and opaque systems, with that concern elevated in relation to ongoing security failures related to Web3 platforms. Safeheron CEO Wade Wang told Cointelegraph that in open-sourcing the framework, the firm is “not threatened by competitors,” but that it is concerned about “slow innovation due to closed systems.” The Singaporean firm was established in 2021. It counts HashKey Capital, Bixin Ventures, Antalpha Ventures, M77 Ventures and Kryptos among its investors. Back in 2022, it raised $7 million in a pre-Series A funding round. At the time, the project’s mission was to make private keys, which individuals use to control and self-custody their digital assets, safer. In terms of products offered, the company markets its MPC Node Suite, a white-label solution that allows clients to build out multi-party computation (MPC) wallet-based applications. It also offers Keyless Wallets that facilitate the development of wallets that don’t require traditional keys.  In February crypto exchange platform BYDFi partnered with Safeheron, leveraging its MPC technology and TEE to build out a key management system.
