Sui Research revealed a way for blockchain wallets to upgrade for quantum safety without a hard fork or address changes. The approach, based on EdDSA cryptography, allows compatible networks like Solana, Sui and Near to transition securely with minimal disruption.
Cryptographer Kostas Chalkias described the breakthrough as the first backward-compatible path to quantum safety for wallets. The upgrade uses zero-knowledge proofs to verify private key control without exposing data, keeping original public keys and supporting dormant accounts.
While praised as one of the most important cryptographic advancements in recent years, the upgrade method does not apply to Bitcoin or Ethereum. These networks use different signature methods, which may need bigger changes to stay secure as quantum tech evolves.
Although quantum computers are not yet capable of breaking blockchain encryption, researchers and developers are racing to prepare. The risk of millions of wallets becoming vulnerable has triggered serious debate in the crypto community.

India’s Income Tax Department is using AI and data tools to identify tax evasion in cryptocurrency transactions. The government collected ₹437 crore in crypto taxes in 2022-2023 using machine learning and digital forensics to spot suspicious activity.
Tax authorities match deducted at source (TDS) data from crypto exchanges to improve compliance. The introduction of the Crypto-Asset Reporting Framework (CARF) also enables automated sharing of tax information, aligning India’s efforts with international tax agreements.
These moves mark a push for greater transparency in India’s digital asset market. Enhanced wallet visibility and automatic data exchange aim to reduce anonymity and curb tax evasion in the crypto space.
India continues to develop regulations focused on consumer protection, cross-border cooperation, and tax compliance, demonstrating a commitment to a more traceable and accountable crypto industry.

The Bank of Korea is forming a virtual asset committee to monitor the country’s growing crypto market and support legislative developments around stablecoins. The new Virtual Asset Team will assist regulators and handle policy matters on digital assets and stablecoins.
As part of this shift, the central bank has renamed its CBDC-related units to reflect a more business-driven approach. The newly titled Digital Currency Team replaces the former Digital Currency Research Team.
Two additional teams, Digital Currency Technology and Digital Currency Infrastructure, will focus on testing platforms and voucher systems using deposit tokens.
Although South Korea’s central bank postponed its CBDC trial in late June due to regulatory uncertainty and concerns from local banks, discussions are expected to resume once legal issues are addressed.
At the same time, the country’s major banks are preparing to issue stablecoins pegged to the Korean won by 2025 or 2026, with support from the Bank of Korea for a bank-led rollout.

Thailand has launched a digital asset sandbox to attract high-spending, tech-savvy tourists by enabling seamless cryptocurrency payments. The initiative lets foreign visitors convert digital assets to Thai baht and spend them using local e-money platforms.
The Securities and Exchange Commission, the Bank of Thailand, and other agencies oversee the regulatory sandbox. It aims to simplify payments from street vendors to luxury retailers, eliminating currency conversion friction and card fees.
Authorities plan to focus on merchant education, compliance, and cybersecurity to support the programme’s success.
The move aligns with Thailand’s broader strategy to become a regional digital finance and blockchain innovation hub. Recent policies include a five-year capital gains tax exemption on crypto sales through local exchanges.
The sandbox could attract fintech firms and blockchain events, signalling Thailand’s ambition to lead in digital asset adoption while maintaining regulatory safeguards.

Indonesia plans to implement fresh tax regulations on cryptocurrency starting August 2025, reclassifying digital assets as financial instruments. The regulatory authority is shifting from Bappebti to the Financial Services Authority, marking a significant overhaul in oversight and licensing.
The upcoming tax increase on crypto transactions aims to boost government revenue, but risks discouraging retail investors due to higher costs. OJK Chair Mahendra Siregar emphasises that the new framework aligns cryptocurrencies with broader financial regulations.
The allowlist of tradable digital assets will nearly double, expanding market opportunities amid the changing landscape.
Fintech startups face challenges adapting to stricter rules and rising operational expenses, potentially disadvantaging them compared to regional competitors like Singapore and Hong Kong.
While retail investors may find initial barriers, more straightforward rules and regulatory sandboxes could foster long-term stability and innovation. Indonesia’s approach will require a careful balance between encouraging growth and ensuring oversight.

The US Department of Justice has moved to seize over $2.3 million in Bitcoin tied to a member of the Chaos ransomware group. The funds, taken from a wallet linked to the individual known as ‘Hors’, are alleged to be proceeds of extortion and money laundering.
Chaos operates as a ransomware-as-a-service group, renting its malware to affiliates targeting Windows, Linux, and NAS systems. The group has been active since early 2025 and is known for encrypting victims’ data while demanding crypto payments under threat of public leaks.
US Federal agents accessed the wallet in April using a recovery seed phrase from an older Electrum platform and transferred the assets to a government-controlled address. The DOJ said the operation demonstrates growing success in disrupting ransomware-related crypto flows.
Despite the seizure, challenges remain as such groups evolve their tactics and benefit from the relative anonymity of decentralised platforms. Authorities stress that continued cross-agency cooperation and advances in blockchain forensics are essential in combating future threats.

Originally due by 4 August, the review period has been extended to 18 September. The proposed fund aims to list on NYSE Arca under the SEC’s commodity-based trust framework.
The regulator also delayed rulings on Grayscale’s Solana Trust, now pushed to 10 October, and Canary Capital’s Litecoin ETF. According to the SEC, more time is needed to assess the applications and address regulatory concerns.
Commissioner Hester Peirce recently warned stakeholders to expect a slow pace in crypto ETF approvals due to ongoing legal and regulatory challenges.
Despite the delays, the SEC has moved faster than in previous cycles. The first spot Bitcoin ETF took over a decade to receive approval, finally gaining the green light in January 2024.
While the Truth Social fund has not drawn formal objections, its ties to Donald Trump have raised concerns among lawmakers over potential conflicts of interest.

Stablecoins are becoming central to a new financial system, says Coinbase. The crypto exchange believes it will soon replace traditional payment networks and power transactions by people and AI agents.
Coinbase vice president Shan Aggarwal described stablecoins as the ‘future of global payments,’ especially when combined with self-custodial wallets. These internet-native bank accounts could expand digital commerce to billions, including those without access to traditional banking.
The firm is building tools like x402 and AgentKit to support AI agents that can autonomously send, receive, and manage stablecoins. Such systems are designed to work around the clock, without the limits of legacy infrastructure.
Beyond the crypto sector, Coinbase sees stablecoins transforming payments for small businesses and underserved regions. By 2030, the company expects nearly everyone online to interact with them, whether knowingly or not.

Tokenisation can remove barriers to green energy investment, allowing more involvement beyond institutional players, says Mete Al, Co-founder of ICB Labs.
Individuals could invest smaller sums and earn passive income by turning assets like solar farms into fractional digital tokens. It allows them to support renewable energy without owning physical infrastructure.
High costs and trust issues limit access to sustainable projects, but blockchain tools can boost confidence and ensure fair rewards.
ICB Labs is already working on a tokenised solar project for 2026. Al emphasises that strong governance and flexible regulation, including regulatory sandboxes, are essential to support innovation in decentralised climate finance.
