Advanced privacy measures

The two firms will work together to develop various blockchain-based service platforms, such as a token securities offering (STO) platform, that will be equipped with strengthened privacy protection technology for data stored on blockchains.

 

Innovation unleashed

Lambda256 has been leveraging its Web3 developer platform Luniverse to work with a plethora of businesses, including those in the security token industry, to help them build, deploy and manage blockchain networks. Some of its solutions include DID, a blockchain-based identity management system; Trace, a blockchain verification and tracking system; and Point, a blockchain-based loyalty rewards solution.

CryptoLab, on the other hand, has developed in-house homomorphic encryption technology that can encrypt data while allowing that data to still be operated on. The firm’s CEO, Chun Jeong-hee, who is also a professor at Seoul National University’s Department of Mathematical Science, was selected as a Fellow of the International Academy of Cryptography (IACR) this year in recognition of his contributions to the development of the field of cryptography.

“By combining Lambda256’s blockchain platform with our homomorphic encryption technology, we look forward to exchanging our technology and capabilities,” said Shin Jun-bum, CTO of Cryptolab. Jason Lee, CISO of Lambda256, also reaffirmed the companies’ joint goal of solving data privacy issues that occur in the blockchain space. He added that they would take this opportunity to bring blockchain to fields like finance and healthcare that are sensitive to data privacy.

NFTs not subject to South Korea’s Virtual Asset User Protection Act

NFTs not subject to South Korea’s Virtual Asset User Protection ActIn anticipation of the Virtual Asset User Protection Act coming into effect in July of next year, the South Korean Financial Services Commission (FSC) has issued an advance notice regarding its subordinate statutes.Photo by Ethan Brooke on UnsplashSeven specific provisionsThe subsidiary regulations under the Act detail seven specific provisions aligned with the Act’s objectives. Firstly, assets categorized as electronic securities, mobile vouchers, deposit tokens backed by the Bank of Korea’s central bank digital currencies (CBDCs) and non-fungible tokens (NFTs) will not be classified as virtual assets and hence, not regulated by this Act. However, in instances where NFTs are used as a means of payment for specific goods or services, they will be regarded as virtual assets.Secondly, banks will take responsibility for managing the deposits of users on cryptocurrency exchanges. This aligns with the Act’s requirement for virtual asset service providers (VASPs) to keep users’ funds separate from their own, either by depositing them in, or entrusting them to, reputable institutions. Under these regulations, banks are required to manage users’ assets in a manner consistent with how investors’ deposits are handled under the Capital Markets Act. This means that banks are allowed to invest VASP users’ assets only in secure instruments, such as state and local government bonds, and are also obligated to pay fees to deposit owners, taking into account the yields of these investments.80% of user assets in cold walletsThe third key aspect of the regulations is that VASPs are required to store a minimum of 80% of user assets in cold wallets, which are not connected to the internet. This is higher than the current requirement of 70%, enhancing the security measures for users of virtual assets. To calculate the total value of a virtual asset at any given time, its total supply is multiplied by its average daily price over the past year. VASPs are obligated to assess the value of virtual assets every month.The fourth regulation mandates that VASPs must enroll in an insurance plan, contribute to a rainy day fund or accumulate reserves. This is to ensure they can fulfill their compensation responsibilities in the event of incidents like security breaches or technical failures. The required preparation amount is set at a minimum of 5% of the user assets stored in hot wallets, as these are more susceptible to risks. VASPs are required to update their compensation thresholds or reserves monthly and must take any necessary actions to comply with these requirements by the next working day following the update.Information disclosure guidelinesAnother regulation addresses the issue of insider trading in the context of the virtual asset market. Under the current Capital Markets Act, information is considered disclosed when it’s made available through disclosure systems of the FSC or the Korea Exchange (KRX). However, since the cryptocurrency market lacks a similar system, the new statute provides criteria for determining when information is deemed disclosed.For instance, if a VASP, including exchanges, releases crucial information about a virtual asset on an exchange and six hours pass, that information is regarded as disclosed. This acknowledges the non-stop nature of the crypto market. Moreover, information disclosed post 6 p.m. is treated as officially disclosed after 9 a.m. the next day.Additionally, if a virtual asset issuer publishes significant information about its token on a website hosting its white paper, the information is deemed public after one day. This is conditional upon the website being publicly accessible and having consistently provided important token information for the preceding six months.These rules aim to provide clarity and fairness in information disclosure in the crypto market, adapting the principles of traditional financial markets to the unique dynamics of virtual assets.No arbitrary suspension of transactionsThe sixth regulation restricts VASPs from arbitrarily halting deposits and withdrawals of virtual assets unless there are justifiable reasons for such actions. Acceptable circumstances for suspending these transactions include situations where the VASP experiences a technical disruption in its system, where regulatory authorities instruct a VASP to cease deposits and withdrawals or where cyberattacks or similar incidents have occurred or are clearly imminent.Lastly, virtual asset exchanges are required to monitor for abnormal transactions continuously. These are transactions that show substantial shifts in the prices or trading volumes of virtual assets, particularly in response to news or rumors that could influence cryptocurrency prices. If VASPs suspect unfair trading practices, they must report to the FSC or the Financial Supervisory Service (FSS). When there is ample evidence of such activities, crypto exchanges are obligated to notify the police or the prosecutors’ office. In addition, the financial regulator has the authority to levy fines based on the prosecution’s decisions or after completing consultations with the prosecution if a year has passed since the day of the report.During the period of advance notice, which spans from Nov. 11 to Jan. 22, the FSC will seek comments from relevant organizations, experts and businesses. This process is aimed at refining the rules and regulations subordinate to the Virtual Asset User Protection Act. Moving forward, the financial authorities plan to publish a set of guidelines and Q&A materials and conduct explanatory sessions, with the goal of ensuring a smooth implementation of the Act.

a16z establishes Seoul presence as Asia’s retail crypto market evolves

Andreessen Horowitz is deepening its bet on Asia’s retail crypto boom, even as trading on South Korea’s largest exchanges has cooled from last year’s peaks. The firm’s crypto arm, a16z crypto, said in a press release that it has opened its first Asia office in Seoul, citing South Korea’s high level of retail participation. Nearly one in three South Korean adults owns cryptocurrency, exceeding the share of stock investors, according to the firm. The move comes as the broader Asia-Pacific region cements its role as a hub of grassroots crypto activity, a trend highlighted in Chainalysis’ 2025 Global Crypto Adoption Index.Photo by Brady Bellini on UnsplashAltcoin-heavy retail marketSouth Korea has been a major contributor to that growth. Bloomberg reported in October that digital assets have increasingly become a long-term savings vehicle for many South Koreans, particularly those trying to purchase homes. Trading on local platforms remains heavily skewed toward higher-risk altcoins, which account for more than 80% of total volume across domestic exchanges. Still, overall activity has dropped sharply over the past year. A November report from Wu Blockchain said trading on Upbit, the country’s largest exchange, is down about 80% from a year earlier. The platform averaged $1.78 billion in daily volume in November 2025, compared with roughly $9 billion in December 2024. Bithumb, the second-largest exchange, saw a similar pullback, with average daily volume falling from $2.45 billion last December to about $890 million this November. Some of that retail liquidity appears to have rotated into equities, with the benchmark KOSPI index up more than 72% year-to-date. Asia’s wealthy to increase crypto exposureEven as spot volumes recede, higher–net–worth investors across the region are signaling longer-term interest. Sygnum’s APAC HNWI Report 2025, cited by Cointelegraph, found that 60% of surveyed high-net-worth individuals plan to increase their crypto exposure over the next two to five years. The report said 87% of respondents already hold digital assets; about half allocate more than 10% of their portfolios, and the average allocation is around 17%. The survey included 270 participants with more than $1 million in investable assets or extensive professional investing experience, drawn from ten Asia-Pacific markets led by Singapore and including Hong Kong, Indonesia, South Korea, and Thailand. Overall, 90% of respondents said they view digital assets as important for long-term wealth preservation and legacy planning, rather than primarily as a speculative trade. Anchored by the new Seoul office, a16z crypto said it plans to provide go-to-market support for portfolio companies seeking to expand in Asia, including help with distribution, partnerships and community building. The effort will be led by Park Sung-mo, whose previous roles include positions at Monad Foundation and Polygon Labs, as Head of APAC go-to-market. Pakistan looks to crypto for financial modernizationPolicy debates elsewhere in Asia also reflect growing interest in digital assets' economic role. At the Bitcoin MENA Conference on Dec. 9, Pakistan’s Virtual Asset Regulatory Authority chairman Bilal Bin Saqib said the country needs to move beyond conventional economic structures and leverage digital assets as a new source of momentum, according to Cointelegraph. He argued that digital assets and blockchain could form part of a new financial architecture for the Global South, not merely serve speculative use cases. The country’s youth-heavy population, about 70% under age 30, was central to his view that it could take a leading position in crypto adoption. Chainalysis’ 2025 index placed Pakistan third worldwide, pointing to how policymakers in emerging markets are increasingly factoring digital assets into long-term economic strategies.

Japan moves to fold crypto into mainstream finance

Japan is moving to pull its cryptocurrency market firmly inside the regulated financial system. A bill approved by the cabinet this month would reclassify digital assets as financial products, while separate developments in blockchain infrastructure and corporate treasury strategy suggest the shift extends well beyond Tokyo's rulebook. The cabinet approved the bill on April 10 to amend the Financial Instruments and Exchange Act, according to Nikkei. The legislation would bring cryptocurrencies under the regulated financial system and mark a departure from the previous framework, which had largely treated them as payment instruments under the Payment Services Act.Photo by Louie Martinez on UnsplashTighter rules take shapeIf enacted, the new rules could take effect as early as 2027. They would prohibit insider trading based on undisclosed information, require issuers to file annual disclosures, and redesignate licensed firms from "crypto-asset exchange operators" to "crypto-asset trading operators." Penalties for operating an unregistered business would also be stiffened, with maximum prison terms raised to 10 years from three and fines increased to 10 million yen ($63,000) from 3 million yen ($19,000). The changes align with the government's broader effort to strengthen market integrity, transparency, and investor protection. The regulatory tightening comes as firms work to build compliant blockchain infrastructure. SBI Ripple Asia, a joint venture between SBI Holdings and Ripple, announced on April 7 that it had completed development of a token issuance system based on the XRP Ledger. The company described the project as financial infrastructure for issuing and managing prepaid payment instruments as tokens on a public blockchain. Such instruments, regulated under current Japanese law, could be handled via apps, websites, and APIs. SBI Ripple Asia added that it completed regulatory registration on March 26 as an issuer of third-party prepaid payment instruments. Corporate treasuries expand crypto betsListed companies are also increasing their exposure to digital assets. WIZE, a Tokyo-listed firm formerly known as Mobcast Holdings, reported holdings of 24,597 SOL as of April 10, valued at roughly $3.13 million (about 498 million yen). The company had announced in October 2025 that it would begin building a Solana reserve, and the latest disclosure suggests corporate crypto holdings in Japan are expanding beyond Bitcoin (BTC).Metaplanet remains the most aggressive example of the trend. Chief Executive Simon Gerovich said on X that the company purchased 5,075 BTC in the first quarter and now holds 40,177 BTC, acquired for a cumulative 623.37 billion yen ($3.92 billion) at an average purchase price of 15,515,598 yen ($97,600) per coin.
