Aevo Launches Novel Index Perpetual ContractAevo, the layer-2 derivatives platform launched by Singapore’s Ribbon Finance earlier this year, has introduced a new index perpetual contract.The contract allows traders to engage in long or short positions based on the market capitalization of accounts within the social application Friend.tech.Photo by Compare Fibre on UnsplashFRIEND-PERPThe FRIEND-PERP market is now live according to The Block, and it has gained significant traction, boasting a daily trading volume of $501,824 and a current trading price of $7.14. This market operates on a unique premise — a perpetual contract, which, unlike conventional futures contracts, does not adhere to an expiration date. This feature is particularly appealing to the crypto trading community, enabling them to seize opportunities without the constraints of time-bound contracts.Surge in interestFriend.tech, the social app at the center of this Aevo product offering, has integrated with Ethereum layer-2 network Base, a blockchain incubated by Coinbase earlier this year. This network, which officially welcomed the public on August 9, has been the center of attention within the crypto sector over the past couple of weeks.The social app enables market participants to buy shares of individuals who hold accounts on X (formerly Twitter). Since its launch earlier this month, the Friend.tech app has grown rapidly. It attracted over 100,000 daily users within 24 hours of its launch.Each user stands to benefit financially from the purchase and sale of their shares, a pioneering approach that has lured prominent figures, including venture capitalist Garry Tan, NBA star Grayson Allen, and celebrated YouTuber FaZe Banks, to the platform.Boost for BaseUS crypto platform Coinbase has embraced Friend.tech as it marks the first major breakthrough use case for its Base blockchain network. This collaborative effort has propelled the Base network to new heights, positioning it among the top cryptocurrency projects by user fee revenue. With $1.4 million in fees generated over the last 24 hours alone, Friend.tech ranks among industry giants, trailing only Ethereum and Lido Finance in this metric, according to data from DeFiLlama.While the app has risen at a phenomenal pace, there are concerns relative to the degree of privacy it affords its users. The public availability of the Friend.tech API used to convert X usernames into wallet addresses has raised the alarm for potential data exposure.A Yearn Finance developer, known by the pseudonym Banteg, used this API to compile a list of Ethereum addresses linked to X accounts. While the community has reassured users that access can be revoked, the implications of this exposure for privacy and security cannot be understated.The Aevo project was first announced by Ribbon Finance in September 2022 and subsequently launched in June. The goal of the project is to convert users from centralized exchanges, bringing them over to the decentralized exchange (DEX) platform.

Bank of Korea and Samsung Team Up for Offline CBDC ResearchIn a move aimed at advancing central bank digital currency (CBDC) technology, the Bank of Korea (BOK) signed a memorandum of understanding (MoU) with Samsung Electronics on Monday, according to a press release. The agreement was sealed during a signing ceremony attended by Lee Seung-heon, BOK’s Senior Deputy Governor, and Choi Won-joon, Executive Vice President and Head of Development in the Mobile Experience (MX) Division at Samsung Electronics.Under the terms of the MoU, both parties have committed to ongoing research on CBDC issued by the Bank of Korea, with a specific focus on collaboration in the offline payment sector. Samsung Electronics had previously participated in the second phase of the CBDC simulation study conducted by the BOK last year.Photo by Aleksandar Pasaric on PexelsCBDC without InternetThe company’s efforts have led to the development of an offline CBDC technology that facilitates transfers and payments via near-field communication (NFC) between devices without requiring an internet connection. These transactions are conducted within the embedded secure element (eSE) chip of Samsung Electronics’ mobile devices, which holds one of the highest levels of security certification, CC EAL 6+.The Evaluation Assurance Level (EAL) is a numeric grading system that measures the security level of tech products and systems according to the Common Criteria (CC) security standard. It ranges from EAL0 to EAL7, with EAL7 representing the highest level of security.Leveraging this technology, the BOK and Samsung will continue their joint research to enhance security in offline payments using Samsung Galaxy smartphones and watches. Additionally, they aim to provide support for stable payments in situations where network connectivity is disrupted, such as during disasters.Growing interest in CBDCsGiven the global interest in CBDCs, with central banks worldwide exploring their potential, the research collaboration between the BOK and Samsung assumes great significance. The results of this partnership will guide further cooperative efforts to develop the international CBDC ecosystem.BOK Senior Deputy Governor Lee Seung-heon emphasized the significance of the joint achievement, expressing optimism that the partnership would keep Korea at the forefront of offline CBDC technology.Samsung’s Executive Vice President Choi Won-joon underscored that the company’s collaboration with the Korean central bank allowed Samsung to utilize its advanced security technology in digital currency. He expected their combined efforts would considerably contribute to the global development of CBDC technology.

Upbit upgrades matching engine to process KRW 1 quadrillion trading volumeSouth Korea’s largest cryptocurrency exchange Upbit has enhanced its matching engine — which matches buy and sell orders from users on the exchange — to be able to handle a daily trading volume of KRW 1 quadrillion (approximately $757.3 billion), according to local news outlet Kyunghyang Games.Photo by Maxim Hopman on UnsplashBecause the crypto market operates nonstop without limits to time or borders, having a solid infrastructure that can seamlessly handle large amounts of data is crucial. Upbit has thus been working on its so-called “Stairway to Heaven” project for the past two years to upgrade its trading infrastructure, including its matching engine.Constant upgradesThe Stairway to Heaven is a long-term project in which Upbit’s operator Dunamu has invested a total of KRW 10 billion (approximately $7.6 million) to adjust to the rapidly advancing crypto industry and improve the performance of the entire market system. The upgradesThe main goal of the project is to upgrade Upbit’s matching engine to be cloud-native and horizontally scalable. The engine is now capable of supporting more than 40,000 transactions per second — a 25-fold increase from the previous version of the engine — allowing it to respond efficiently to surges in user traffic. In the event of a traffic spike, the system can handle more than 100,000 transactions per second with additional servers, the exchange said.“Unlike the way traditional finance approaches ledger management, our cloud-native architecture allows us to flexibly respond to surges in traffic,” Upbit said. “We will continue to make various system improvements to offer a stable investment environment.”Elevating the user experienceIn addition to upgrading its matching engine, Upbit has recently revamped its UI/UX to include price chart updates by second increments and an overview of profits and losses. The exchange plans to continue its multifaceted efforts in service quality, security and investor protection to become a domestically and globally recognized exchange.
