Taiko Labs Raises Funding to Build Ethereum-Equivalent zkEVM

Vietnamese authorities have dismantled a criminal ring that used cryptocurrency to launder illicit gambling profits, AFP reported, citing local media. The group converted local currency into digital assets such as USDT and Ethereum, routing funds to users for online betting. Operating multi-layered investment websites, the network grew to as many as 20,000 users and managed 25 million accounts, despite Vietnam’s ban on cryptocurrency. In total, the transactions involved were valued at roughly $3.8 billion. Police allege that millions of dollars were funneled into real estate, luxury cars, and cross-border cash transfers. While the money laundering probe continues, the gambling case has already produced convictions. Four Vietnamese siblings who ran the network, along with 39 other defendants, received sentences in Ho Chi Minh City ranging from a three-year suspended term to 13 years in prison. An Indian national identified as the alleged mastermind remains at large.Photo by Amanda Jones on UnsplashThai police foil crypto-themed fraudElsewhere in the region, police in neighboring Thailand busted a South Korean crime syndicate based in Pattaya that allegedly stole more than 20 billion won ($14.2 million) through fraud schemes that invoked cryptocurrency as a lure, along with other scams, the Chosun Ilbo reported. The scam ring reportedly obtained customer data from a lottery tip site and collected money from victims either by posing as agents offering membership refunds or by claiming to provide compensation for leaked personal information, which they disguised as opportunities to buy digital assets. In addition to these schemes, the syndicate ran romance scams and posed as authorities. Thai police arrested 20 members in a June resort raid. Nine more suspects, including ringleaders, remain in custody awaiting extradition. Seoul police said that, in total, 25 members have been caught, 21 of whom are now detained. Authorities believe the network may be linked to other groups in Thailand and are widening the investigation. Europe uncovers $120M crypto fraudCrypto crimes aren’t limited to Asia. In Europe, police arrested five suspects in a Eurojust-led operation that uncovered an online investment scam worth at least €100 million ($116.8 million). Operating since 2018 across 23 countries, the scheme lured victims with platforms promising high returns, then funneled deposits through Lithuanian accounts before disappearing. In a report by the Organized Crime and Corruption Reporting Project, Elliptic Chief Scientist Tom Robinson said such schemes often have little to do with cryptocurrency itself, instead exploiting its technical obscurity and the allure of quick gains. Beyond scams, outright theft from crypto platforms is also climbing. A Chainalysis study found that by the end of June 2025, more than $2.17 billion had been stolen from exchanges and related platforms—already surpassing the total for all of 2024. The firm projects losses could reach $4 billion by year-end. The single largest incident was the February hack of the Bybit exchange, in which thieves took $1.5 billion, roughly 69% of all funds stolen in the first half of this year. Crypto crime turns increasingly violentThe Chainalysis report also flagged a rise in physical attacks, in which criminals use violence or coercion to force individuals to hand over their crypto holdings. The firm warned that 2025 may log nearly twice as many cases as the worst year on record, noting that the attacks often rise and fall with expectations for Bitcoin’s price. In response to these threats, Chainalysis stressed the need for a multilayered approach to crypto security. It advised service providers to strengthen internal controls through regular audits and employee screening, while upgrading wallet infrastructure and other technical defenses. For individuals, the firm said, keeping holdings discreet has become as critical as technical safeguards, especially amid the rise in physical attacks. 

Mercari, one of Japan's leading e-commerce platforms, has declared its intention to accept bitcoin payments starting from June of this year. The decision, which was reported by Japanese financial media outlet Nikkei on Friday, outlines that the processing of bitcoin payments will be managed through Mercari's Tokyo-based crypto subsidiary, Melcoin.Photo by Dmytro Demidko on UnsplashSeamless BTC conversionIt's noteworthy that Melcoin will convert all BTC payments into yen, ensuring vendors receive fiat currency despite the buyer's choice of bitcoin for payment. While the company won't display prices in bitcoin, listing items for sale in fiat yen, customers will have the option to select BTC as a payment method during the purchase process on the platform. In recent months, Mercari has introduced various crypto-related products, including the Mercari bitcoin crypto trading service. This service allows users to buy and sell bitcoin using the proceeds from their sales on the platform. The integration of a loyalty points system further enhances the crypto trading experience, enabling Mercari users to exchange their points for bitcoin. Remarkably, Mercari announced that its bitcoin trading service surpassed the 1 million user milestone in October, just seven months after its launch. At the time of the launch of the trading service, the company outlined that it would “make bitcoin more accessible to people who have never tried crypto trading before.” Notably, around 80% of the crypto users on Mercari had no prior experience with crypto-asset trading in June of the previous year. Expanding its crypto-related offering to include bitcoin payments unleashes much more potential relative to crypto adoption. 22 million monthly usersEstablished in 2013, Mercari has evolved into Japan's largest community marketplace platform, boasting 22 million monthly users as of July 2023. It’s a flea market application, making it a consumer-to-consumer platform that could play a significant role in bringing about bitcoin adoption in Japan among ordinary people. The company has also expanded its footprint internationally, with a particular focus on Europe. Market observers have labeled Mercari's crypto service, along with a competitor operated by Rakuten, as a potential "gateway" for bitcoin and crypto investors and traders. Rakuten, another major Japanese e-commerce platform deeply involved in the crypto space for an extended period, operates the Rakuten Wallet crypto trading service. Like Mercari, Rakuten has integrated its loyalty points program with its crypto arm, allowing users to trade their points for crypto-assets. Rakuten had also emerged last year among a shortlist of Asian companies expressing an interest in purchasing failed crypto exchange FTX. A recent survey highlighted the growing influence of these e-commerce giants in the crypto space. Japanese individuals who entered the coin trading scene towards the end of 2022 overwhelmingly favored either Mercari's bitcoin trading app (24.7%) or Rakuten's Rakuten Wallet platform (24.2%). This revelation dealt a blow to traditional crypto exchanges, with bitFlyer, the long-standing market leader, securing the third position with a share of 11.3%. This move contributes towards a more progressive crypto environment in Japan, where lawmakers recently indicated a willingness to consider making tax rules more accommodative of the crypto sector.

SK Geo Centric Launches Korea’s First Blockchain-Based Plastic Recycling PlatformSK Geo Centric, a chemical affiliate of South Korea’s second largest conglomerate SK Group, has announced today the launch of the country’s first blockchain-based plastic recycling platform. This endeavor aims to ensure the safe and widespread use of recycled plastics by customers.Photo by mali maeder on PexelsAddressing environmental pollutionPlastic recycling has emerged as a promising solution to address environmental pollution. However, concerns have been raised about the source and safety of collected plastic waste. Recognizing the demand from customer manufacturers who utilize recycled plastic, SK Geo Centric developed the new platform to provide more comprehensive information than what is required by the International Sustainability and Carbon Certification (ISCC) PLUS, which the company previously obtained.The ISCC PLUS certification is a voluntary program designed for circular products, including chemicals and plastics, derived from using renewable energy sources. It is administered by ISCC, an independent multi-stakeholder initiative based in Germany. While adhering to the same certification standards as ISCC EU, ISCC PLUS allows for customization to meet the requirements of other markets.Blockchain techSK Geo Centric’s innovative platform utilizes blockchain technology to record and store every step of the plastic recycling process, ensuring transparency and traceability. Intermediate producers and end-users can access the complete history of recycled plastic by scanning the QR code on the product. Information such as the types, sources, and proportions of plastic waste used in a product, as well as the quality of materials, will be readily available.The history records will be stored in the form of non-fungible tokens (NFTs), providing proof of authenticity for the product. This information can be shared via email among the relevant parties. Manufacturers can now demonstrate to their customers the specific recycled materials used in their products.Market growth and efficient distributionSK Geo Centric believes that the systematic management of history records will enhance the credibility of the plastic recycling market, leading to its growth. Transparent records of high-quality and safe plastic waste will facilitate trading. Furthermore, real-time information on the recycled plastic market will enable efficient distribution within the industry.Recycling facilityIn addition to the platform, SK Geo Centric plans to establish the Advanced Recycle Cluster in Ulsan, a city in southern Korea, later this year. The presence of this plastic recycling facility is expected to expand the scale of the recycling market and attract more participants.Na Kyung-soo, CEO of SK Geo Centric, highlighted the importance of trust among market participants in fostering the development of the recycled plastic sector.
