Coinone adds new security features

OKX Ventures, the investment wing of the Seychelles-based cryptocurrency exchange OKX, has disclosed a strategic A-round investment in Polyhedra Network. Details of the investment have been outlined through a press release published via PRNewswire on Tuesday. Specializing in the creation of Web3 infrastructure, Polyhedra Network places a premium on interoperability, scalability and privacy, leveraging advanced zero-knowledge (ZK) proof technology.Photo by Precondo CA on UnsplashInteroperability with privacyA ZK proof provides the ability for one party to cryptographically prove to another party that it possesses a certain piece of information without having to reveal the actual underlying information to the other party. Central to Polyhedra Network's product offering is its zkBridge protocol, a system facilitating trustless and efficient cross-chain infrastructure for both layer-1 and layer-2 interoperability. The protocol empowers the receiving chain to verify specific state transitions on the sending chain. This approach ensures robust security without external assumptions, effectively reducing the costs associated with on-chain verification. Polyhedra Network made an initial impact in 2023 with the launch of the "zkBridge Mainnet Alpha." That product enabled interoperability over 20 layer-1 and layer-2 blockchains, including well-known networks such as Bitcoin, Ethereum, BNB Chain and Arbitrum. Distributed proof systemThe innovative strides of Polyhedra Network, which was founded in the United States by James Zhang, Tiancheng Xie and Nikhil Shah, continued in 2023 with the introduction of deVirgo, a novel distributed proof system expediting proof generation. The deVirgo protocol also incorporates recursive proofs which trim on-chain proof verification costs associated with zkBridge. Last month, Polyhedra Network unveiled its Bitcoin messaging protocol with zkBridge, ushering trustless interoperability into the Bitcoin ecosystem through the use of ZK-proof technology. Asian backingBy championing entrepreneurs contributing to the blockchain industry's advancement, OKX Ventures is helping to build innovative companies, bringing global resources and historical experience to the forefront of blockchain projects. It is one of many Asia-centric venture firms to do so. Polyhedra has secured backing from Hong Kong’s Animoca Brands and HashKey Group, Singapore’s UOB Venture Management, NGC Ventures, Signum Capital and Foresight Ventures, alongside KuCoin Ventures. In an initial funding round in February 2023, the UC Berkeley team attracted $10 million in funding. By April, a pre-Series A round had raised a further $15 million. Dora Yue, the founder of OKX Ventures, expressed their honor in participating in the investment in Polyhedra Network's interoperability infrastructure. Yue lauded the creativity demonstrated by Polyhedra Network's team in developing advanced ZK-proof mechanisms, emphasizing the balance achieved between ZK interoperability and scalability. OKX Ventures, with an initial capital commitment of $100 million, is committed to supporting Polyhedra Network's vision of seamlessly connecting the Web2 and Web3 worlds, aiming to attract a more extensive user base to the industry. As the investment arm of the global crypto exchange platform, it dedicates itself to exploring top-tier blockchain projects on a global scale. Its focus is on fostering cutting-edge blockchain technology innovation, aspiring to support the healthy development of the global blockchain space and investing in long-term structural value.

Cartesi Launches Inaugural dApp on Ethereum MainnetSingapore-based Cartesi, the app-specific roll-up protocol with a virtual machine running Linux distributions, has introduced its inaugural dApp.The decentralized application, aptly named Honeypot, has been designed to serve as a platform for developers and ethical hackers to rigorously scrutinize the security of the Cartesi protocol’s underlying codebase, all in exchange for lucrative bounties.Photo by Michael Förtsch on UnsplashHoneypot deploymentAccording to a press release published on Tuesday, Honeypot is set to fulfill the vital role of stress-testing Cartesi’s foundational code on the Ethereum mainnet. The successful deployment of Honeypot will pave the way for Cartesi’s technology to be employed in a multitude of other dApps. Notably, a unique aspect of Honeypot is the tempting incentive it offers. The first individual to successfully hack it will be entitled to drain the sum of 1.77 million Cartesi tokens, equivalent to $220,000, after one year without any constraints.Embedded within the Honeypot dApp’s backend code is an algorithm that only permits the Cartesi Foundation’s depositor account to make fund withdrawals. Participants who dare to take on this code-breaking challenge must successfully navigate the intricacies of the algorithm to claim the reward.Developer Advocacy contributor to Cartesi, Gabriel Barros, stated: “We want to welcome all developers to test Cartesi’s Rollup infrastructure — but in a gamified challenge.”Aiding dApp developmentCartesi stands as a Layer 2 network specifically designed to streamline the development of intricate and powerful dApps. Its mission is to bridge the gap between conventional development practices and blockchain-based solutions, attempting to offer a seamless transition for developers.At its core, Cartesi introduces a mechanism that enables dApps to execute resource-intensive computations off-chain within a Linux environment. Crucially, these off-chain computations are verifiable by the blockchain, ensuring that the final results remain consistent across all nodes. This approach empowers developers to harness existing software and tools while ensuring compatibility with the blockchain.Linux insideThe choice of a Linux environment is pivotal to Cartesi’s framework. Linux enjoys widespread usage worldwide, particularly in server environments, making it a familiar and well-adopted platform. This familiarity extends to the extensive array of tools and libraries available within the Linux ecosystem, which are leveraged by developers for a myriad of traditional web applications.Gabriel Barros underlined Cartesi’s mission, stating:“Cartesi’s goal is to eliminate the limitations Web3 developers face by enabling them to import decades of familiar programming tools, libraries, and languages to the blockchain. By doing so, Cartesi unlocks a new realm of possibilities, allowing developers to surpass what was previously imaginable with earlier web3 applications.”Cartesi’s introduction of the Honeypot dApp on the Ethereum mainnet signifies a significant step towards ensuring the security and robustness of its protocol. Furthermore, it demonstrates Cartesi’s intentions in attempting to foster a vibrant and innovative ecosystem for developers in the blockchain space.

Crypto-Friendly Xapo Bank Enters Indian MarketXapo Bank, a cryptocurrency bank based in Gibraltar, has set its sights on India and plans to offer banking and cryptocurrency services in the country.Xapo, which claims to be the first bank in the world to integrate traditional private banking with crypto, issued a press release which was published via Bloomberg on Thursday to announce the development.Photo by Julian Yu on UnsplashMassive market opportunityWith a population of over 1.3 billion, India presents a massive opportunity for Xapo Bank, which is backed by prominent investors like SoftBank, DST Global, and Ribbit Capital. This move comes at a time when India has seen impressive foreign inflows of $15.5 billion in the first quarter of 2023.The CEO of Xapo Bank, Seamus Rocca, suggested that the absence of conventional banking services in certain parts of South Asia has created a void that Xapo Bank aims to fill. By providing innovative financial products and services, the bank hopes to empower individuals and businesses with access to reliable and inclusive banking solutions.Rocca stated that the move “represents an opportunity to provide our hybrid banking and investment solutions to its large underserved populations, bridging an important gap in the region’s financial systems and allowing its savvy savers, investors, and professionals the freedom to explore their financial potential with a single mobile application.”Competitive interest rate offeringOne of the attractive features of Xapo Bank for customers in India is its competitive interest rates on deposits. The bank offers attractive returns, with a yearly interest rate of 4.10% on US dollar deposits and 1.00% on Bitcoin deposits. Notably, the daily interest payments on Bitcoin deposits are distributed in the smallest denomination of the cryptocurrency, a satoshi.Xapo Bank’s expansion into India aligns with the country’s projected economic growth of 6.3%, according to Fitch Ratings. Despite the worldwide economic downturn, India’s GDP demonstrated robust growth of 6.1% in the first quarter, showcasing the country’s resilience.Government policy challengesHowever, Xapo Bank will face challenges as it enters the Indian market. The world’s most populous country has implemented strict measures regarding cryptocurrencies, including a 30% tax on all cryptocurrency income and the elimination of deductibility for losses. Such regulations could potentially impact Xapo Bank’s operations and profitability in India.Authorities like the country’s central bank, the Reserve Bank of India (RBI), have been more inclined to encourage the financial services sector to adopt blockchain technology rather than offer cryptocurrencies directly. Earlier this month, American multinational financial services company JPMorgan Chase partnered with six major Indian banks in a blockchain offering that aims to improve the interbank settlement process.Nevertheless, Xapo Bank remains undeterred, recognizing the immense potential of India’s growing economy and the urgent need for accessible financial services. The bank’s expansion promises to create opportunities for individuals and businesses across the nation, contributing to India’s economic development and financial inclusion.Moreover, Xapo Bank’s entry into India reflects a broader trend of fintech innovation and the convergence of traditional banking and digital currencies. As the world becomes increasingly interconnected, financial institutions like Xapo Bank are reshaping the financial services landscape by offering forward-thinking solutions that bridge gaps, ultimately empowering individuals and fostering economic growth.
