India’s NPCI Looks to Recruit Blockchain Talent

Rising Cryptocurrency Arbitrage Transactions Raise Concerns in South KoreaThe number of arbitrage transactions between South Korean and foreign cryptocurrency exchanges has been experiencing a notable uptick, according to a report by local media outlet Maeil Business Newspaper.In recent developments, foreign actors engaging in price manipulation have been transferring substantial amounts of cryptocurrency assets to Korean exchanges, driving up prices. Subsequently, they transfer these tokens from Korean exchanges back to overseas platforms, capitalizing on the price discrepancies to generate profits.Photo by Maxim Hopman on UnsplashBithumb’s case in H1According to documents submitted to Kim Hee-gon, a member of the ruling political party People Power Party, on Monday, KRW 3.4 trillion ($2.6 billion) worth of tokens were moved from Bithumb, a leading Korean cryptocurrency exchange, to foreign trading platforms during the first half of this year. Although this figure marks a 40% decrease compared to H1 2022’s KRW 5.7 trillion, primarily due to the significant decline in token prices across the cryptocurrency market, it’s noteworthy that the number of transactions has seen a significant increase.Other exchangesGopax, another major exchange in the nation, recorded token outflows totaling KRW 12.3 billion. On the other hand, Upbit, Coinone, and Korbit, which are also prominent exchanges, declined to provide data due to reasons like confidentiality concerns. However, given that Upbit holds an 82.0% share of the Korean crypto market, nearly four times larger than Bithumb’s share (14.2%), it is suspected that the volume of tokens transferred from Upbit to foreign platforms would likely have followed a similar proportion.While the value of tokens sent from Bithumb to overseas operators saw a year-over-year decrease, the number of transactions surged to 231,302, nearly doubling the figure of H1 2022’s 124,048 transactions. The average transaction size was KRW 14.7 million.Even though the overall enthusiasm for cryptocurrencies might have cooled off since last year, the spike in the number of transactions suggests that there’s been a surge in arbitrage trading between Korea and foreign markets.Kimchi premiumEarlier this month, a significant transaction caught the eye of cryptocurrency market observers in South Korea. On September 1, crypto data analytics firm Arkham identified that 170,000 CyberConnect (CYBER) tokens were transferred to Bithumb from a crypto wallet thought to be owned by DWF Labs, a firm specializing in cryptocurrency trading and investment. The timing of the transaction coincides with a period during which the Kimchi premium for CYBER exceeded 100%. The Kimchi premium refers to the crypto price gap between Korean exchanges and their foreign counterparts.The complicating factor here is that DWF Labs is a foreign entity that is managed by a foreign team.The use of corporate accounts is virtually prohibited in the Korean crypto market. The Travel Rule mandates that any transfers of tokens between Korean and international exchanges must go through accounts that have been verified under Know Your Customer (KYC) guidelines. Given these regulations, there are growing suspicions within the crypto community that foreign venture capitalists may have used accounts in borrowed names to conduct sales on Korean exchanges, which are restricted to Korean citizens. However, it’s worth noting that there is currently no legal basis for taking punitive action even if borrowed-name accounts were indeed used.Lawmaker Kim commented on the limitations of current financial regulations aimed at preventing money laundering in the cryptocurrency market. Despite efforts by financial authorities, including the introduction of the Travel Rule, Kim stated that these measures have not been very effective. He emphasized the urgency of enhancing the regulatory framework to curb potential illicit activities involving cryptocurrencies, such as those exploiting market arbitrage opportunities.

Coti plans transition to Ethereum layer-2 network in 2024Israeli blockchain developer Coti plans to introduce a scalable, privacy-focused Ethereum layer-2 protocol in 2024. This strategic move aims to extend Coti’s privacy-centric features to a wider audience within the Ethereum ecosystem.Photo by Zoltan Tasi on UnsplashIncorporating ‘garbled circuits’Taking to the X social media platform on Wednesday, Coti unveiled its plan to transition from a standalone protocol to an Ethereum layer-2. The centerpiece of the project, which Coti has termed “Coti v2: a privacy-centric Ethereum L2,” is a cryptographic method known as “garbled circuits.”Garbled circuits are a cryptographic primitive that enables two or more parties to evaluate an arbitrary Boolean circuit securely, without revealing any information beyond the output, all while using a constant number of communication rounds. This innovative approach enables the processing of transactions without exposing sensitive information and data, aligning with the platform’s commitment to privacy.Having originated in the 1980s, garbling protocols have evolved into a crucial element of privacy-preserving technologies, excelling in scenarios where confidential data needs to be part of a computation without revealing the information itself.Focusing on privacyCoti CEO Shahaf Bar-Geffen emphasized the significance of this privacy-oriented protocol, stating:“Sensitive data transmitted as public information on a blockchain is a bug, not a feature.”Bar-Geffen highlighted the protocol’s ability to prevent sensitive data from being exposed to competitors, partners and clients engaged in transactions on Coti’s chain. The CEO elaborated on how garbling protocols differentiate Coti v2 by facilitating transactions and smart contract executions where details remain private between involved parties.The Coti CEO emphasized the critical role of such privacy features in decentralized finance applications, where transaction confidentiality is as essential as transaction integrity. Coti claims that other platforms focusing solely on anonymity for privacy may face regulatory challenges and might not provide a compliant foundation for the broader ecosystem.Targeting specific use casesCoti envisions its protocol catering specifically to use cases demanding advanced privacy provisions in finance and healthcare. Currently designed for enterprises, Coti’s existing protocol enables the management of blockchain-based products such as custom-branded tokens, wallets, website integrations and fiat on-and-off ramps.In a blog post on Medium, the blockchain startup outlined that in addition to privacy, v2 will enable smart contracts, EVM compatibility and Solidity programming, alongside the features currently offered by v1. Notwithstanding these new features on the v2 product, the company confirmed to The Block that in respect of Coti’s original Cardano-based product, “Coti’s work with Cardano continues. We have a project built there called Djed, and that will continue to remain on Cardano.” Djed is an ADA-backed stablecoin pegged to the U.S. dollar.The anticipated release of Coti v2’s developer net in the second quarter of 2024 signals a move towards realizing the potential in advancing Ethereum’s privacy standards. As a layer-1 protocol, Coti presently contributes to Web3 applications by providing digital infrastructure, including tools for wallets, tokens and payment modules, with a total value locked of $31 million.The upcoming integration as a privacy-centric layer-2 positions Coti as a key player in enhancing Ethereum’s capabilities and fostering a more secure and confidential blockchain experience.

South Korea’s largest crypto exchange, Upbit, suffered a security breach on Nov. 27 that resulted in the theft of 44.5 billion won ($30.4 million) in digital assets, all taken from the exchange’s hot wallets. The stolen tokens were all Solana-based, and Upbit CEO Oh Kyoung-suk said in a statement that no users will incur losses, as the company will cover the full amount with its own reserves.Photo by FlyD on UnsplashHot-wallet breach hits 24 tokensThe exchange said in a statement that the compromised tokens were transferred to an unknown external wallet at around 7:42 p.m. UTC on Nov. 26. In total, 24 cryptocurrencies were affected, all within the Solana ecosystem. The stolen assets ranged from infrastructure tokens such as Solana (SOL) to staking-related assets like Jito (JTO), along with the stablecoin USD Coin (USDC) and memecoins including Bonk (BONK), Moodeng (MOODENG), and Official Trump (TRUMP). According to Oh, the breach was followed by an emergency security review of the affected networks and wallets. He added that all remaining assets were moved to cold storage to prevent further unauthorized transfers. Oh also said the exchange is working to trace the stolen assets and block on-chain movements wherever possible, noting that Solayer (LAYER) tokens worth 2.3 billion won ($1.6 million) have already been frozen. Upbit is also reaching out to relevant projects and institutions for assistance. This marks Upbit’s second theft case. The first took place on Nov. 27, 2019, exactly six years ago to the day, according to News1. Authorities focus on Lazarus’ involvementFinancial authorities are investigating the incident, and North Korea’s Lazarus Group is being treated as the leading suspect, the Maeil Business Newspaper reported. Lazarus is also believed to have been behind the 58 billion won ($40 million) worth of Ethereum (ETH) stolen from Upbit in 2019. A government official told the paper that the latest breach did not appear to stem from a server intrusion but may have involved a stolen administrator account, allowing the attackers to impersonate internal staff and move assets—similar to the method used in the 2019 case. Security analysts echoed that assessment. One investigator said the stolen funds moved through exchange wallets before being mixed, a pattern often linked to Lazarus. He added that mixers, which are prohibited in Financial Action Task Force (FATF)-member jurisdictions, make tracing difficult and that attackers typically route assets through countries outside that framework, further pointing to North Korea. Following the incident, Upbit suspended deposits and withdrawals for all assets and said services will resume once security is fully verified. The halt has also affected trading dynamics on the exchange, with CryptoQuant CEO Ki Young Ju noting that retail investors are fueling altcoin spikes as arbitrage bots remain offline. Dunamu, Naver set $6.8B growth planThe security crisis struck at a particularly sensitive moment for Upbit’s operator, Dunamu, overshadowing what was intended to be a celebratory corporate milestone. On that same day, Dunamu, Naver, and Naver Financial held a joint press conference to outline their global expansion strategy. Dunamu brings its blockchain and crypto infrastructure, Naver contributes its position as Korea’s dominant search engine, and Naver Financial adds its payment platform serving 34 million users. The event came after reports that Naver Financial and Dunamu had approved a merger plan through a comprehensive share swap, with the ratio set at 1 to 2.54. The three companies said they will combine their respective strengths to invest 10 trillion won ($6.8 billion) over the next five years in building an ecosystem centered on Web3 and artificial intelligence (AI).During the press conference, Naver CEO Choi Soo-yeon said no decisions have been made on a Nasdaq listing for the newly combined Naver Financial–Dunamu entity or on whether it might eventually merge with Naver, according to TechM. She said dual listings remain a matter requiring national consensus. Choi also noted that while Naver Financial is a Naver subsidiary, Dunamu is the larger partner, and a later merger between the combined entity and Naver is unlikely.
