India’s WazirX Partners with TaxNodes to Simplify Taxes

The People’s Bank of China (PBOC) plans to roll out a new structure for its central bank digital currency (CBDC) operations, moving the digital yuan into a deposit-based role within the commercial banking system beginning Jan. 1, 2026. Lu Lei, a deputy governor of the PBOC, announced the update, marking a new direction after nearly a decade of pilot programs. According to a report by FTChinese, the move fits into Beijing’s broader economic planning, as authorities seek to reinforce China’s role in global finance while containing risks tied to loosely regulated digital activity. The deputy governor said China will continue to run the digital yuan under a two-tier system, with the central bank responsible for rules and infrastructure, while commercial banks manage wallets, payments, and compliance. He added that the arrangement is designed to prevent banks from being sidelined and to limit shadow banking risks associated with digital payment platforms outside the regulated system.Photo by Eric Prouzet on UnsplashDigital yuan transactions top $2.3TThe announcement comes as use of the digital yuan, known as the e-CNY, continues to rise. By late November 2025, the system had handled 3.48 billion transactions with a total value of 16.7 trillion yuan ($2.3 trillion). There are about 230 million personal wallets and 18.84 million corporate wallets. Beyond domestic use, the e-CNY is being positioned for international trade. Lu pointed to progress on mBridge, a cross-border payments project involving multiple central banks. The platform has processed 4,047 transactions worth the equivalent of 387.2 billion yuan ($55.3 billion), with the digital yuan accounting for about 95.3% of the settlement value. The deputy governor also sounded a note of caution on private-sector innovation, saying the rapid growth of digital assets and stablecoins could complicate the conduct of monetary policy. He said central banks need to ensure that new payment tools do not undermine macroeconomic stability or allow money to circulate beyond regulated channels. Hong Kong to license crypto dealers, custodiansAs Beijing moves to strengthen its state-backed currency framework, Hong Kong is also tightening oversight of the crypto market. On Dec. 24, the city’s Financial Services and the Treasury Bureau (FSTB) and the Securities and Futures Commission (SFC) released their conclusions on proposed legislation to regulate virtual asset dealing and custodial services. Following the implementation of the Stablecoins Ordinance in August, regulators are now moving to require firms offering crypto dealing or custody services in Hong Kong to obtain licenses and operate under regulatory supervision. They also began seeking feedback on whether to extend oversight to virtual asset advisory and management providers, with the proposed framework modeled on existing securities market rules. In a separate development underscoring the contrast between state-backed and decentralized digital currencies in the region, reports this month pointed to a sharp drop in Bitcoin network activity linked to mainland China. BTC hashrate drop seen amid China mining changesKong Jianping, CEO of Nasdaq-listed Web3 infrastructure firm Nano Labs, said on the social media platform X that the global Bitcoin network’s hashrate fell by about 100 exahashes per second, or roughly 8%, around Dec. 15. He attributed the decline to the shutdown of an estimated 400,000 mining rigs, mainly in Xinjiang. A lower hashrate means less computing power is securing the network, reducing competition among miners that validate transactions. China has maintained a broad ban on crypto trading and mining since 2021. Industry outlet Wu Blockchain said the reasons for the latest shutdowns were unclear. 

As the cryptocurrency market anticipates the approval of a spot bitcoin exchange-traded fund (ETF) in the United States and the subsequent boost to bitcoin’s unit price, Arthur Hayes, Chief Investment Officer (CIO) of family office Maelstrom, has issued a warning of potential market turbulence. Hayes, better known as the founder of crypto derivatives platform BitMEX, has moved on to Hong Kong-based Maelstrom, a family office that invests in early stage infrastructure ventures that implicate a move towards the decentralization of everything.Photo by Kanchanara on UnsplashMacroeconomic risk factorsIn a detailed blog post on Friday, Hayes outlines a number of macroeconomic variables that could lead to a bitcoin unit price downturn. Hayes begins by highlighting the depletion of the Federal Reserve’s reverse repo program (RRP), which has served as a significant driver for risky assets over the past year. This program allows qualified banks and investment firms to park cash and earn interest on it. The RRP balance has rapidly declined from a record high of $2.5 trillion at the end of 2022 to $700 billion. Hayes projects it to reach its historical average of $200 billion by March. As this liquidity source dwindles, he anticipates negative impacts on bonds and stocks, as well as cryptocurrencies. Fed BTFP expirationThe second factor contributing to the potential market turmoil is the expiration of the Bank Term Funding Program (BTFP) on March 12. This crucial Fed facility is designed to provide longer-term loans to commercial banks. The mechanism aids banking sector stability. Hayes is concerned that the BTFP might not be extended. Such an eventuality could lead to bankruptcy for banks holding massive unrealized losses on their bond holdings. It could lead to a “liquidity rug pull” event reminiscent of the banking crisis in March of the previous year. The crypto OG predicts that such an eventuality would force a response. “The combination of a lack of liquidity gushing from the RRP and the lack of printed money to cover the bond losses on banks’ balance sheets will decimate the financial markets globally,” he wrote. Hayes asserts that the combination of reduced liquidity from the RRP and the lack of printed money to cover bond losses could have a global impact on financial markets. In response to this scenario, he predicts that the Fed will cut interest rates during its March 20 meeting and reinstate the BTFP funding line. ‘Healthy’ correctionIn terms of bitcoin’s price, Hayes foresees a “healthy” correction of 20% to 30% from early March prices if the outlined scenario unfolds. However, he suggests the decline could be as much as 40% if BTC rallies to $60,000-$70,000 in the coming weeks. Despite this temporary plunge, Hayes remains optimistic about bitcoin’s resilience, emphasizing its status as a neutral reserve hard currency that is not a liability of the banking system and is traded globally. In a recent podcast appearance, Hayes expressed the view that the business model of U.S. dollar stablecoin issuer Tether will be challenged once multinational banks receive the go-ahead to offer fiat-backed stablecoins. Overall, Arthur Hayes has urged investors to be cautious and to prepare for potential market volatility in March, emphasizing the importance of understanding the interconnected factors influencing both traditional finance and the cryptocurrency market. 

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.
