AndUs to implement ZK rollups on Its public permissionless blockchainAndUs, the South Korean developer of public permissionless blockchain Anduschain, announced on Wednesday (local time) that it is preparing to implement zero-knowledge (ZK) rollup technology into its blockchain to enhance scalability and security. ZK rollups are layer-2 scaling solutions that move transactions off-chain to increase throughput on the Ethereum mainnet.Photo by Shubham Dhage on UnsplashPerspective on ZK rollupsMany Korean projects are focused on developing various layer-2 solutions. Against this backdrop, Park Sung-jun, CEO of AndUs and a Ph.D. in cryptography, believes ZK rollups will eventually surpass the currently popular optimistic rollups as the mainstream technology. Although both ZK and optimistic rollups improve scalability by processing transactions off-chain, they differ in their approaches: ZK rollups rely on validity proofs, while optimistic rollups utilize fraud proofs.Introduction next yearHolding this belief, AndUs has formulated a ZK rollup implementation plan and has begun its development, aiming to introduce it by next year. Park commented that this upgrade will significantly improve the blockchain’s speed and expressed plans to offer the world’s lowest gas fees.AndUs claims that their DEB consensus algorithm focuses on fairness, enabling nodes to engage in mining without preconditions. Furthermore, Anduschain’s ZK rollups will be fully compatible with Ethereum virtual machines (EVMs), facilitating a seamless transition of decentralized applications (dApps). The cryptocurrency used on Anduschain is named DEB, and it is currently listed on cryptocurrency exchanges ProBit Global and MEXC, according to CoinMarketCap.AndUs has been participating in the Tech Incubator Program for Startups (TIPS) program, which is led by private investments under the guidance of the Korean Ministry of SMEs and Startups.

Aptos Labs, the developers behind the Aptos layer-1 blockchain, has entered the Japanese market through the acquisition of HashPalette, a blockchain network concerned with the issuance, management and distribution of non-fungible tokens (NFTs). HashPalette informed stakeholders of the development on Oct. through an X post, alongside a press release published on its behalf by Japanese public relations company PR Times. Photo by Tianshu Liu on UnsplashExpanding Asian presenceUp until now, HashPalette has been a wholly owned subsidiary of HashPort, a blockchain-related consulting and infrastructure provider based in Tokyo. This acquisition sees the project transfer to being a wholly owned subsidiary of Aptos Labs. Accordingly, this will mean that applications developed by HashPalette will be migrated onto the Aptos Network. Similarly, the Palette Chain blockchain will migrate over to Aptos. From Aptos Labs’ perspective, the acquisition enables it to expand its blockchain ecosystem in Japan and within Asia more broadly. Aptos Labs Co-Founder Mo Shaikh described the acquisition as an investment in “the talented builders and creators of the region.”  Deal pending approvals, closing conditionsWhile the parties have announced the acquisition, the deal is still subject to required approvals being granted, together with various closing conditions related to the sale being met. Addressing the need to close out the deal, HashPalette tweeted:“HashPort and Aptos Labs will work closely together in the transition and will take great care to ensure that all stakeholders, including PLT and ELF holders, are not disadvantaged by the migration.” The PLT token is HashPalette’s native token. According to the project’s whitepaper, it has utility when it comes to the payment of NFT issuance fees and node management fees relative to the Palette Chain. Additionally, it can be used to pay for NFTs issued on the Palette Chain and for subscription payments related to applications developed on top of the network. The ELF token is a crypto asset utilized within THE LAND ELF Crossing, an NFT farming game which was developed by HashPalette and issued on the Palette Chain. The game is being marketed in Japan with the assistance of Animoca Brands following a partnership earlier this year. The companies have agreed to gradually migrate NFTs which had been issued on Palette Chain, relative to the EXPO2025 digital wallet developed by HashPort, to the Aptos Network. Once that migration has been achieved, it’s envisaged that the Aptos Network will become the only blockchain associated with the EXPO2025 digital wallet. Unresolved Palette Chain issuesFrom the point of view of the development team behind HashPalette, it was outlined in the press release that the move goes beyond a simple financial transaction. It acknowledged that “Palette Chain still has many issues.”  Against that background, the team believes that in order to further accelerate the social implementation of Web3, it has “considered how to make services built on Palette Chain more scalable and usable, and to enable smoother access to the global Web3 market.” That consideration has brought the project team to the conclusion that migrating to the Aptos Network offers the best path forward. At the time of writing, Aptos’ APT token was trading at $8.93, up 12.44% over the course of 24 hours, according to CoinMarketCap data.

Japanese Crypto Firm Pafin to Introduce DeFi Asset Management PlatformA Japanese company specializing in cryptocurrency services is preparing to launch a DeFi asset management platform.Photo by Shubham Dhage on UnsplashDeFi asset managementPafin, the company behind Cryptact, a service that automates cryptocurrency profit and loss (P&L) calculations, is set to introduce Defitact on June 5. Defitact is a platform designed to consolidate transactions involving decentralized finance (DeFi) assets and NFTs, complemented by illustrative charts. Pafin claims that it is the first provider of crypto P&L calculations to offer blockchain asset management in the Japanese language.The company envisions a broad array of services through Cryptact, from asset management to P&L calculations, to support all Web3 activities in today’s digital landscape.Beta test for subscribersStarting from May 29, Pafin will roll out a beta test for Defitact, exclusive to Cryptact newsletter subscribers. Subscribers will be able to access the service by entering their wallet addresses in the URL provided with the newsletter, which will be sent on the beta test launch date. The newsletter will be sent to those who sign up by May 28, and registration for a Cryptact account is free.This service emerges amidst the growing prominence of Web3, with DeFi — a financial service leveraging blockchain technology — standing out as one of its most rapidly evolving sectors. As of the close of 2021, the DeFi market had a near $100 billion valuation, according to a report by the Japan Research Institute.The nature of DeFi, lacking a centralized administrator, places the onus of crypto wallet management on individuals. The Defitact service seeks to resolve the inconvenience of monitoring and managing real-time transactions on DeFi platforms, typically operating outside crypto exchanges.Available in Japanese and EnglishAs a free, bilingual (Japanese and English) service, Defitact provides a transaction history and displays crypto market capitalization in three fiat currencies: the Japanese yen, the US dollar, and the euro.Pafin’s future plans include integrating Defitact with Cryptact, adding an NFT management service, and enabling the aggregation of multiple wallets for efficient digital asset portfolio management.
