According to CoinPost, Kinexys, a blockchain division of JPMorgan, announced the addition of five currencies to its Blockchain Deposit Account (BDA) network: Australian Dollar (AUD), Hong Kong Dollar (HKD), Japanese Yen (JPY), Renminbi (RMB), and Singapore Dollar (SGD). This expands the total supported currencies to eight, including the existing Euro, British Pound, and US Dollar, making it the platform with the most supported currencies in the global blockchain settlement and on-chain foreign exchange field.The BDA operates on JPMorgan's private blockchain, supporting 24/7 settlement and programmable payment features. Japanese energy giant JERA Global Markets became the first enterprise to adopt the Yen BDA, aimed at optimizing internal fund flow management and liquidity allocation. Currently, Kinexys has processed a cumulative transaction volume exceeding $40 trillion, with a daily transaction volume of over $7 billion.

According to CoinDesk, blockchain analysis company Chainalysis has released a new methodological proposal aimed at establishing a unified on-chain fund tracking standard framework for law enforcement agencies and investigators, to identify address clusters and determine their possible control relationships.The proposal defines the on-chain analysis structure in the form of "ontology," focusing on systematically breaking down the currently unstandardized concept of "cluster" in the industry into wallet segments and functional roles, and describing on-chain relationships through a two-layer structure: the first layer defines the transaction graph structure, and the second layer assesses inference confidence.Chainalysis stated that the framework aims to enhance the interpretability and legal applicability of on-chain forensic methods, and is designed and validated based on its practical experience in relevant cases within the U.S. Department of Justice, including the analytical application in the mixing service Bitcoin Fog case.The company's Chief Scientist Jacob Illum pointed out that the goal of the proposal is to answer "on what evidence basis can these addresses be considered to belong to the same entity," while emphasizing that on-chain analysis itself cannot directly identify the ultimate user identity and still requires legal investigative methods combined with centralized entities such as exchanges.Chainalysis indicated that the standard proposal is currently open for discussion within the industry, hoping to promote the formation of more unified technical specifications for on-chain analysis methods in the fields of law enforcement and compliance.

The Ethereum Layer2 project Taiko announced that the attack path that occurred on June 21 has been blocked, and the related fixes have been reviewed by independent security experts, ensuring that user funds will not suffer losses.The team has developed a four-step restart plan: the first step is to deploy the fix and confirm the final state of the chain is correct, ensuring there are no forged checkpoints or claim paths that can be exploited by attackers, which will be reviewed by the Security Council; the second step is to replenish the cross-chain bridge funds, ensuring that L2 assets are fully backed 1:1, and that anyone can verify on-chain; the third step is to restore network operation, reopening transfer, exchange, and trading functions on L2; the fourth step is for the Security Council to submit a proposal to lift the suspension of the cross-chain bridge after confirming that the chain can achieve stable final confirmation and the network operates stably.Users will then be free to transfer funds between Taiko and other chains, and the team will implement a conservative withdrawal limit as an additional safety measure, but it is expected that there will be no restrictions on users' normal asset transfers.

According to Documenting Bitcoin, the Bitcoin network successfully mined a block using the Stratum V2 protocol for the first time. Compared to the currently widely used Stratum V1, Stratum V2 allows miners to independently construct block templates and choose transactions to package, rather than being completely determined by the mining pool. This retains the mining pool's revenue distribution mechanism while reducing the mining pool's control over transaction packaging, which helps enhance the decentralization and censorship resistance of Bitcoin mining.

Base officially released an analysis report on the interruption of block production, which disclosed that the Base mainnet experienced two interruptions in block production on June 25 and 26, lasting 116 minutes and 20 minutes respectively. The security of on-chain assets was not affected, and funds remained in a secure state.The root cause of the incident stemmed from a logic flaw in the sequencer's block construction: after a transaction execution failure, the old journal state was not correctly cleared, leading to gas calculation errors during the execution of subsequent valid transactions, which in turn generated invalid state transition blocks, causing the entire L2 chain to pause block production.Base stated that the issue has been resolved through a patch, and it will strengthen the protocol's fuzz testing and stress testing systems to identify potential malicious transaction paths, while also optimizing monitoring and operational processes. Additionally, there are plans to introduce a recovery mechanism to enhance the ability to recover quickly from similar incidents in the future.

According to official news, Base disclosed at 00:27 Beijing time that the mainnet experienced an interruption due to block production issues. The team confirmed that the problem originated from an anomalous block interfering with the construction of subsequent blocks, and all funds are safe. At 1:53, the team announced that the new block ordering had been restored, and internal nodes were synchronizing normally. Teams running validation nodes need to restart Base nodes to restore synchronization. At 3:22, the team announced that block production had returned to normal, and various applications and infrastructure were gradually coming back online as nodes were restarted. The team has identified the root cause of this interruption and will prioritize releasing a complete post-incident analysis report.In addition, The Block reported that this interruption occurred on the same day that Base planned to conduct the Beryl upgrade at 02:00 Beijing time, but it is claimed to be unrelated to the scheduled maintenance.

According to Cointelegraph, a study based on 857,000 active users of Polymarket shows that about 60% of users who placed their first bets during the World Cup had never interacted with blockchain protocols before.Alvin Kan, Chief Operating Officer of Bitget Wallet, stated that prediction markets have changed the traditional logic for crypto users to get involved—users no longer need to understand blockchain technology first, but can participate directly because they have opinions on real-world events. This has made prediction markets a new entry point for some users into the crypto space.Data shows that the trading volume of Polymarket's World Cup champion contracts has exceeded $3.1 billion, with sports contracts contributing over $4.9 billion in trading volume to Polymarket in the past 30 days, and reaching $8.5 billion on Kalshi, becoming the main trading category on both platforms.

Blockchain data infrastructure startup Cambrian has completed a $6 million seed round financing, led by Franklin Templeton and Polychain Capital, with participation from Flow Traders, Selini Capital, Paper Ventures, Nomad Capital, and others.Cambrian also previously secured $5.9 million in pre-seed financing led by a16z Crypto Startup Accelerator, bringing the total funding to $11.9 million. It is reported that Cambrian was established in 2024 and currently provides APIs for institutions and AI Agents, covering real-time and historical on-chain data such as yield, risk, lending rates, trading activity, liquidity positions, and market sentiment, helping users allocate capital on-chain.The company plans to expand its existing APIs into a verifiable blockchain data oracle network, serving institutional financial clients, AI Agent builders, and protocols that need reliable data to control the flow of funds. Unlike traditional oracles that mainly provide price data, Cambrian aims to aggregate lending protocol data, DEX liquidity, social sentiment, developer activity, and historical market data.According to Cambrian, its platform has processed millions of API calls, currently indexing approximately $4.5 billion TVL across four major lending protocols, tracking 1,789 vaults under 895 curators, and monitoring over 320,000 DEX liquidity pools on Base and Solana. The company also plans to expand trading data support, adding Hyperliquid and richer perpetual contract data.

Du Jun from ABCDE Lianchuang stated that over the years of twists and turns, the crypto field has returned to the payment narrative in the Bitcoin white paper. He will continue to invest in the crypto field and still believes that blockchain will eventually reconstruct financial infrastructure.

NEAR officially announced the next major protocol upgrade SPICE (Separation of Consensus and Execution), which is a key step towards Nightshade 3. After the upgrade is completed, the NEAR block time will be reduced from the current 600 milliseconds to 200 milliseconds, achieving about a 3x speedup, approaching the maximum speed allowed by physical conditions. The core of SPICE is to decouple the consensus layer from the execution layer, allowing validators to complete block consensus without waiting for transaction execution, thereby reducing latency and supporting more complex, time-consuming transactions.NEAR stated that this upgrade will be the largest underlying architecture change since Stateless Validation in 2024. After the upgrade, the transaction experience of applications such as NEAR Intents and near.com will be further enhanced. Defuse Labs CEO Alex Shevchenko indicated that the final confirmation time for NEAR is expected to drop to about 0.4 seconds, faster than Visa's standard of about 3 seconds, achieving a payment experience close to "completed in the blink of an eye."NEAR also mentioned that faster block times are crucial for the AI Agent economy, enabling high-speed payments and complex transactions between agents, and allowing longer tasks to be executed across multiple blocks. Additionally, SPICE will pave the way for Nightshade 3 and lay the foundation for achieving cross-shard atomic execution in the future. The NEAR development team stated that this will help address the development complexity and potential vulnerabilities brought by asynchronous environments, improving network scalability and security.

According to mempool data, miners mined an empty block at Bitcoin height 954352 (that is, the block only contains a transaction for the block reward Coinbase), with only a 62-second time interval from the previous block height.Miners pack empty blocks out of economic considerations, and this is the wisest choice for miners. In order to make full use of this time for mining and avoid conflicts with transactions packed in the parent block, miners cannot fill the block with transactions, meaning miners can only attempt to mine empty blocks.
