In the past six years, the five major virtual asset platforms in South Korea have experienced 57 incidents of hacking and system failures, with a total compensation amount reaching 7 billion won

According to the Korea Herald, the five major virtual asset trading platforms in South Korea (Upbit, Bithumb, Coinone, Korbit, Gopax) have experienced a total of 57 hacking and system failure incidents over the past six years (from 2020 to April 2026), with a total compensation amount of approximately 7 billion Korean won (about 5.1 million USD). By exchange, the number of incidents is as follows: Upbit 26 incidents, Bithumb 14 incidents, Gopax 8 incidents, Coinone 6 incidents, Korbit 3 incidents.Among them, Bithumb compensated approximately 2.5 billion Korean won (about 1.8 million USD) for the BTC misissue incident in February this year, Upbit compensated approximately 790 million Korean won (about 570,000 USD) for a hacking incident in November 2025, and compensated approximately 3.2 billion Korean won (about 2.3 million USD) for a system incident on December 3, 2024. It is worth noting that the standards for compiling incident reports by exchanges and the scale and form of compensation vary. For example, Gopax counts errors that occur when viewing the asset list as system failures, while Bithumb only counts situations where all customers encounter difficulties using core services for more than 10 minutes as system failures.In addition, Bithumb also provided some applicants who suffered losses due to system failures with free fee vouchers instead of cash compensation. The compensation amounts for system failures are as follows: Upbit approximately 3.21 billion Korean won, Bithumb approximately 3.2 billion Korean won, Coinone approximately 49 million Korean won. Korbit and Gopax did not provide any compensation.

The second trial of the 660,000 yuan virtual currency theft case in Wuhan, China, has been revised: the main culprit was sentenced to ten years and six months in prison, and the amount stolen was determined based on the actual payment cost incurred by the victim

According to the "Procuratorial Daily," Lin, Zeng, and Dai conspired to use virtual currency trading as a pretext. During the trading process, they secretly filmed the victim's digital wallet private key and, after the virtual currency was credited, secretly logged into the victim's wallet to reverse the transaction, transferring the related virtual currency back to their controlled accounts. The three committed the crime three times, causing the victim a total economic loss of 660,000 yuan.The first-instance court held that in the absence of a clear judicial interpretation regarding the valuation method of virtual currency and sentencing standards, it was inappropriate to directly determine the amount involved as particularly huge based on the victim's purchase amount of 660,000 yuan. Therefore, they sentenced the three based on "other serious circumstances," imposing prison terms ranging from eight years to five years and six months, along with fines. The Hanyang District Procuratorate of Wuhan City in Hubei Province subsequently filed an appeal, which was supported by the Wuhan City Procuratorate.The prosecution argued that the first-instance court applied the law incorrectly and imposed an excessively light sentence. Prosecutor Dai Wentao of the Wuhan City Procuratorate stated that in the case where the victim had a clear loss amount to refer to, it was contradictory and legally erroneous to claim that the value of virtual currency could not be determined. In judicial practice, using the resale price and transaction price as the basis for determining the amount of theft has become mainstream, and determining the value of virtual currency based on the actual cost paid by the victim has factual, legal, and practical basis.The Intermediate Court of Wuhan accepted the prosecution's opinion in the second instance, revoked the corresponding content of the original judgment, and changed the determination of the theft amount to particularly huge. It sentenced the principal offender Lin to ten years and six months in prison for theft, and sentenced the accomplices Zeng and Dai to eight years in prison each, along with fines.

Aleo releases a white paper on privacy stablecoins, proposing a permissionless institutional-level privacy stablecoin architecture

Aleo released the privacy stablecoin white paper "Stablecoin Privacy," stating that the privacy layer is the key infrastructure missing for blockchain payment rails to be adopted by mainstream institutions. Aleo indicated that as the GENIUS Act provides opportunities for the widespread adoption of stablecoins, the issue of permanently public transaction information on public blockchains may still hinder institutions from using stablecoins in scenarios such as payroll, fund management, and vendor payments.Aleo claims that existing solutions do not adequately meet the needs of institutions in terms of privacy protection and risk management. The white paper proposes a permissionless private stablecoin architecture based on Aleo, which introduces programmable risk mitigation mechanisms while protecting transaction privacy through zero-knowledge technology and programmable smart contracts, allowing institutions to conduct private transactions without sacrificing compliance and risk control.It is reported that the team members behind this white paper have long been dedicated to research at the intersection of cryptography, policy, and financial systems. Aleo's Global Policy Director Yaya J. Fanusie, member of the Crypto Innovation Council and former Global Financial Crimes Compliance Officer at Coinbase Valerie-Leila Jaber, and cryptographer and Johns Hopkins University Computer Science Professor Matthew Green possess rare practical experience in private payments, financial regulation, and zero-knowledge cryptography.
