Data Labs leverages blockchain technology for data-based travel itinerary appFounded in 2021, Data Labs is changing the landscape of travel by leveraging blockchain and NFT technology to offer a wallet service called “MyInfo Market,” where users can store and control their own data, according to an article published by Korean news outlet Data News.In particular, MyInfo Market can be used in tandem with the company’s travel app Yeohaengdaelo, which utilizes users’ travel-related data to recommend travel destinations and organize and share itineraries. Users can directly manage their personal preference information on MyInfo Market and selectively submit the information necessary to receive rewards. “It’s not just a travel itinerary app, it’s also a way for individuals to earn money using their own data,” said Kim Jong-hyun, CEO of Data Labs.Photo by Eva Darron on UnsplashSeamless travel experienceYeohaengdaelo integrates Naver Blog, Instagram and KakaoTalk services into one app, aimed at relieving the stress that comes with travel preparation, Kim explained. It utilizes data such as the region a user is traveling to, their travel companions and information on facilities, as well as their travel preferences and patterns. The app also provides real-life services such as discounts at designated restaurants near the travel site.Building trust and valueThe company explained that it intends to maintain a cyclical data ecosystem where users can willingly provide their data to get travel recommendations and receive suitable compensation for that information in return. Because the ecosystem is blockchain-based, it provides a safe method of personal information management.Since the launch of Yeohaengdaelo in July, Data Labs has been developing a business model that can secure a solid user base and revenue for affiliated businesses. It expects to reach 55,000 members next year and 2.14 million members by 2028. The company also expects to use the business model as a basis for generating KRW 500 million (approximately $386,000) in revenue next year by linking marketing channels, issuing discount coupons for kids’ amenities and providing data royalties.In the future, Data Labs plans to expand Yeohaengdaelo to include not only travel preparation services but also information on various discounts that users can receive based on the location they are in. Efforts like this will be necessary to provide unique user experiences, the company said.Data Labs is also currently receiving support through Y&Archer’s tourism acceleration program. Y&Archer is a Korean investment and acceleration firm known for its AC Program, which discovers, accelerates and supports startups through various projects.“In the past, companies profited from personal data, but Yeohaengdaelo allows individuals to monetize their data. Our goal is to create a world where individuals can regain the rights (to their own data) and be at the center of Web3 content,” Kim said.

Bank of Korea Conducts Successful CBDC Pilot Test with Financial InstitutionsThe Bank of Korea (BOK) announced yesterday in a press release that its central bank digital currency (CBDC) pilot program operated successfully in a practical setting involving multiple financial institutions.Testing environmentsPreviously, the CBDC system was tested in an isolated cloud environment. In this recent test, the system was installed on the servers of various financial institutions over a five-month period to evaluate its performance.The 1.2 billion KRW ($905,000) project included the participation of six companies, such as Kakao’s Krust Universe, KakaoBank, and KakaoPay, as well as 14 banks and the Korea Financial Telecommunications and Clearings Institute. Kookmin, Shinhan, and Woori were among the participating banks.Four scenariosThe BOK and financial institutions tested the system’s performance under four scenarios: increasing transaction requests per second, increasing the number of active users, reducing the transaction queue size, and adjusting the block generation time ratio.The increase in transaction requests led to a 10% decrease in transactions per second (TPS), from 2,100 TPS to 1,900 TPS, compared to the single cloud environment test. This result is still deemed acceptable, as the highest TPS recorded in the current small payment infrastructure network is 1,200, which occurs on paydays and other high-transaction days.Issues such as slower response times arose with higher transaction request volumes but were resolved by enlarging the transaction queue size and increasing the block formation time proportion in the block generation process. The block generation process involves two stages: block formation, where transactions are recorded, and block validation, where transactions are verified.Greater stabilityThe test demonstrated that transaction errors at individual institutions did not affect others, suggesting that a distributed ledger system offers greater management stability than a centralized system. However, institutional officers cited challenges in problem-solving and communication when using the distributed ledger system.The BOK plans to involve more institutions in ongoing experiments this year, supporting them in testing their smart contracts on the CBDC pilot system.Photo by Bundo Kim on Unsplash

Korean Firms Team Up to Boost Biofuel Use Through Blockchain TechSouth Korean tech service provider SK C&C announced on Thursday that it inked an agreement with Recycle Ledger, a company that operates a service for tracking transactions related to recycling resources. Through this collaboration, the two firms aim to employ ChainZ, SK C&C’s blockchain application programming interface (API) platform, to track the journey of waste cooking oil.Photo by Sigmund on UnsplashBroadening ESG operationsThis deal allows SK C&C to broaden its environmental, social, and governance (ESG) operations into the waste management sector through blockchain tech, strengthening its position as a prominent provider of ESG solutions and a leader in Korea’s net-zero digital intelligent transport systems (ITS).Prior to this initiative, SK C&C launched Click ESG, a comprehensive ESG management platform, and Centero, a carbon credit trading platform, enhancing its ESG offerings.Recycle Ledger operates an ESG platform built on blockchain technology, enabling easier tracking of waste and recycling resources while promoting transparent information sharing. The firm is currently developing a tracking management system for waste cooking oil, specifically tailored for aviation biofuels, a rapidly emerging market sector.Global trendThe US, the EU, and other developed nations are implementing regulations that require sustainability certification for biomaterials and enhancing systems to monitor and manage the collection process of waste cooking oil. This oil can serve as an ingredient for biofuels.This stricter regulatory landscape emerged partly in response to instances of greenwashing, where conventional biofuels are falsely presented as being derived from used cooking oil. Such deceptive practices became prevalent due to the escalating prices of biofuels.Since the adoption of the International Air Transport Association’s (IATA) resolution known as Fly Net Zero in October 2021, which commits airlines to achieve net zero carbon by 2050, many developments have taken place. The EU has imposed a requirement for suppliers to blend at least 2% of sustainable aviation fuel (SAF) into kerosene starting from 2025, planning to boost this to 63% by 2050. The US, meanwhile, aims for 100% SAF use in its aviation fuel demand by 2050.Waste cooking oil trackerIn light of these developments, Recycle Ledger plans to introduce a blockchain-based service that comprehensively tracks and manages the complete life cycle of waste cooking oil, from restaurants to biofuel producers. By utilizing blockchain technology, the company aims to help waste cooking oil exporters obtain sustainability certifications for biomaterials.Recycle Ledger is collaborating with fintech solution provider Woori FIS and electronic payment firm Payup to develop a system that addresses the inconvenience of cash transactions for recyclable resources. Recycle Ledger is also exploring the implementation of a carbon point system for waste cooking oil emissions.Blockchain-based data flow trackingMeanwhile, SK C&C will provide its blockchain mainnet ChainZ as an API to help Recycle Ledger provide its services swiftly and securely.SK C&C’s data tracing API is designed to document information across all data management stages, including data creation, provision, receipt, analysis, and deletion, offering an environment to track data flow.Recycle Ledger CEO Kim Ki-jong said that its platform could enhance the value of recyclable resources and prevent greenwashing by storing transaction data on the blockchain.Choi Chul, the head of the Web3 tech group at SK C&C, touted ChainZ’s benefits, including data security, transparency, and integrity. He highlighted the need for data traceability and transparency within the ESG sector given the multiple stakeholders involved, and affirmed ChainZ’s readiness to satisfy the demand for new ESG services.
