AndUs to implement ZK rollups on Its public permissionless blockchain

Web3 & Enterprise·November 22, 2023, 7:18 AM

AndUs, 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.

Perspective on ZK rollups

Many 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 year

Holding 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.

Binance survey reveals evolving security habits of Asian platform users

Global crypto exchange Binance has carried out a survey which reveals that the security habits of Asian platform users are evolving positively.Photo by Vadim Artyukhin on UnsplashUsers responding to more sophisticated scamsIn a blog post published by the crypto exchange platform on May 6, Binance revealed that it had carried out a survey of nearly 30,000 platform users across Asia. The company’s takeaway following analysis of the survey data is that “scams are evolving — and so are crypto users.” The firm suggested that users are “stepping up their security game,” with exchanges facing growing demand from their users for real-time protection and smarter security tools. Increasing use of 2FAThe exchange platform found that 80.5% of survey respondents now use Binance two-factor authentication (2FA). While the use of 2FA is definitely a move in the right direction, it doesn’t guarantee the safety of a user’s digital assets.  In an article published by Forbes last month Forbes Contributor Davey Winder warned that infostealer malware can compromise 2FA codes in as little as 10 seconds. In June of last year, an OKX user lost $2 million in crypto to a hacker who utilized AI despite the victim having used Google’s 2FA. Double-checking transfersThe survey found that 73.3% of users double-check transfers before sending digital assets. Due to the nature of decentralized cryptocurrency, crypto transactions are not easily reversed and are usually irreversible. That puts a greater responsibility on crypto users to ensure that they are sending funds to the appropriate wallet address. Double-checking transfer addresses is not only necessary due to human error. Malware is also used by hackers to spoof such addresses, tricking the sender into sending the digital assets to their address rather than the one that was originally intended. It emerged in May 2024 that a Bitcoin trader had lost more than $70 million in Bitcoin in an “address poisoning” scam. Binance itself had warned users last September that “clipper malware,” which intercepts clipboard data on a user’s phone or desktop, replacing copied wallet addresses with alternative addresses under the hacker’s control, is increasingly being employed in hacking attempts. While the survey has revealed a positive evolution in the security habits of Asian platform users, there’s still room for further improvement. Just 17.6% of survey respondents utilize address whitelisting, a measure that restricts account user access to a safe list of pre-defined trusted addresses. Only 21.5% of survey respondents use anti-phishing codes as a security mechanism. The objective of phishing is to steal data, install malware on a user’s device or otherwise gain account access. An anti-phishing code aids the user in verifying the authenticity of emails and texts from a specific service. Security remains a major issue within crypto. Last month, hackers employed social engineering tactics to steal $330 million in Bitcoin from an elderly American victim. Exchange platforms themselves continue to struggle to safeguard user funds. Earlier this year, Binance competitor, Dubai-headquartered Bybit, suffered a $1.5 billion hack believed to have been perpetrated by North Korea’s Lazarus Group. Lazarus is also thought to have been behind a $235 million crypto theft at Indian crypto exchange WazirX in July 2024.

Japan targets 2028 for crypto ETF approval as global markets weigh U.S. risks

Japan is taking steps to approve exchange-traded funds (ETFs) tracking spot cryptocurrency prices, a regulatory shift that could take effect as early as 2028, according to a CoinPost report citing a Jan. 25 article by Nikkei.Photo by Jezael Melgoza on UnsplashThe timeline reflects the legislative steps required before retail investors can access digital assets through traditional brokerage accounts. Japan’s financial regulator, the Financial Services Agency (FSA), plans to amend investment regulations to permit cryptocurrencies as eligible assets for investment trusts. SBI, Nomura prepare crypto productsAccording to the report, major financial heavyweights, including SBI Holdings and Nomura Holdings, are already developing products in anticipation of regulatory approval. If cleared by the Tokyo Stock Exchange, the listings would allow Japanese investors to trade Bitcoin products alongside standard stock or gold ETFs. Institutional interest appears robust. A Nikkei survey conducted in November identified six major firms weighing the development of crypto investment trusts: Nomura Asset Management, SBI Global Asset Management, Daiwa, Asset Management One, Amova, and Mitsubishi UFJ. These companies are reportedly exploring products tailored for both retail and institutional clients. However, the 2028 target is largely dictated by the pace of tax reform. Government plans call for crypto profits to be taxed at a uniform 20%, replacing the current progressive system and putting digital assets on the same footing as equities and foreign exchange. The revised tax treatment would also apply to crypto ETFs and derivatives. At present, crypto gains are treated as miscellaneous income, leaving investors subject to progressive tax rates that can climb to roughly 55% once local levies are included. Crypto market slides amid volatility As Japan maps out its long-term regulatory course, recent market activity has been volatile, tied to potential currency interventions and U.S. political uncertainty. Bitcoin briefly surged to $91,000 over the weekend, a move CoinDesk reports some traders attribute to suspected Japanese intervention in the foreign exchange market. The theory suggests a transient reversal in the yen’s recent weakness forced an unwinding of leveraged carry trades, temporarily boosting the world’s largest cryptocurrency. However, the momentum was short-lived. Bitcoin is currently trading near $87,500, down 1.45% over the previous 24 hours. Market sentiment has been dampened by fears of a U.S. government shutdown and renewed trade tensions. On the prediction market platform Polymarket, participants have priced in a 78% chance of another government shutdown by Jan. 31. Compounding investor anxiety are President Donald Trump’s tariff threats. Trump recently warned he would impose 100% tariffs on Canada should the U.S. neighbor sign a trade deal with China. Canadian Prime Minister Mark Carney has since announced that Ottawa has no plans to forge such an agreement, according to CNBC. Monetary policy remains a headwind for risk assets. Ahead of the Federal Reserve’s interest rate decision this week, the CME FedWatch Tool indicates traders expect the central bank to hold rates steady in the 3.5% to 3.75% range at the Jan. 28 meeting. Markets are pricing in only a 2.8% chance of a 0.5% cut. The prospect of rates remaining unchanged offers little incentive for investors to pivot aggressively toward riskier assets like crypto. Gold, silver reach record levels This risk-averse environment has funneled capital into precious metals, driving prices to record levels. Both gold and silver have hit all-time highs, surpassing $5,000 per ounce and $106 per ounce, respectively. Amid the uncertainty, retail investors in neighboring markets are showing caution. In South Korea, a weekly survey by CoinNess and Cratos of 2,000 respondents found that 43.2% of investors are holding existing crypto positions without making additional purchases. Another 22.7% said they are actively trading, while 21.4% reported having no current position and waiting for a more favorable entry point. The remaining 12.7% said they are staying out of the market entirely.
