Tencent Hunyuan has released and open-sourced the next-generation large language model Hy4 preview. This model has a total of 770B parameters and 49B active parameters, with a context length exceeding 1M. It demonstrates strong capabilities in real productivity tasks such as coding, office work, and science, firmly placing it in the top tier of open-source models. Hy4 preview significantly expands in model size, context length, and data scale, and enhances real-world performance through high-quality data co-built with Tencent experts in software engineering, gaming, finance, security, and deep collaboration with products like WorkBuddy.In software engineering, the model enhances understanding, planning, debugging, and verification capabilities for long-range development tasks, enabling the construction of complex front-end projects like a Three.js miniature town from scratch. In game development, it supports generating playable prototypes from a single sentence and can complete a full demo in Unity. In smart office applications, it can handle complex financial audits, filtering, analyzing, and delivering from multiple documents. In scientific research, it achieves acceleration in tasks such as molecular dynamics simulations and has initially formed a recursive self-improvement feedback loop.Hy4 preview can be experienced in Tencent products such as WorkBuddy/CodeBuddy domestic and international versions, Yuanbao, ima, and can also be accessed via API calls through Tencent Cloud Tokenhub and OpenRouter. WorkBuddy/CodeBuddy will launch a limited-time free activity for two weeks. Since the reconstruction of the infrastructure, the Hunyuan large model has iterated a major version approximately every two months, continuously optimizing through a preview-first and formal version-following approach.

The Supernova upgrade of MultiversX decouples consensus from execution, allowing the network to reach consensus on blocks before processing transactions. Before the upgrade, block production followed a sequential model: proposers selected transactions, executed them locally, and submitted blocks containing the results, while validators had to re-execute the same transactions before voting, making execution part of the consensus critical path. Supernova changes this order: proposers select transactions and directly propose blocks without prior execution; validators can immediately vote once they confirm the proposal complies with protocol rules, while execution occurs asynchronously in the background, with execution results typically referenced and notarized in the next block header, lagging consensus by about one block (approximately 600 milliseconds).To address the validity verification issues brought by decoupling, Supernova introduces a virtual memory pool state that tracks pending nonces, expected balance consumption, and transactions that have been proposed but whose execution results have not yet reached consensus, providing proposers with a forward-looking account view. Meanwhile, the Execution-Result Inclusion Estimator (EIE) limits the number of execution results that can be referenced in a block based on the capacity that the minimum specification node can safely handle; an automatic backpressure mechanism reduces block capacity when execution lags. Supernova has been producing 600-millisecond blocks on the testnet and devnet since August 20, with the mainnet expected to activate on September 10, 2026.

The blockchain network BNB Chain has enabled the Pasteur hard fork on the BNB Smart Chain (BSC) mainnet. The upgrade involves cross-chain bridge validation, validator authorization, staking, and governance security, while enhancing block capacity without changing the 450 milliseconds block time.This upgrade includes BEP-682, BEP-695, and BEP-675, which respectively involve duplicate validator entries, validator key rotation and penalty governance, and block submission processes. In the internal testing environment QANet, the new process increased throughput from 1,237 transactions per second to 2,324 transactions per second, but the related data comes from controlled tests and not mainnet measurement results.

According to The Defiant, Arbitrum activated the ArbOS 61 Elara upgrade on August 20, adding optional protocol-level transaction filtering, priority fee support, and alternative data availability interfaces for dedicated chains, while adjusting the base fee management and expanding the Stylus contract capacity of Arbitrum One. The compliance filtering feature is turned off by default and requires the chain owner to actively configure external compliance service providers (such as TRM Labs or Chainalysis) and set rules, executing through a dual mechanism of simulated transactions and on-chain guardians.The priority fee feature is also turned off by default and requires the chain owner to enable it through pre-compilation. The collection of priority fees on Arbitrum One still requires a separate DAO vote. Elara also introduced the BaseFeeManager contract, allowing Offchain Labs to adjust the base fee within the DAO-approved range of 0.01 to 0.1 gwei, with a validity period of two years. The code size limit for Stylus contracts has been increased from 24KB to 96KB, which does not apply to Solidity contracts.

According to Crypto.news, Cardano governance company Intersect has updated its roadmap, dividing the Dijkstra upgrade into two phases: the first phase will go live in Q4 2026, including the Linear Leios scaling solution, nested transactions, new serialization structures, and PlutusV4 changes; the second phase will activate the Ouroboros Peras consensus protocol through a separate hard fork, with a target date of Q2 2027.Linear Leios introduces an endorsement block mechanism, where additional transactions are certified by the stake committee to enhance throughput while retaining the existing Praos security model. Additionally, Cardano plans to submit an amendment to add Dijkstra-related parameters by September 11. The Rust node client Amaru has already acquired relay and chain synchronization capabilities, with a mainnet block production target set for November 2026. Intersect emphasizes that the above timelines are estimates rather than commitments, and governance and community testing may lead to delays in activation.

According to Harmony monitoring, Harmony stated that it is advancing the rollback plan and has reached an agreement with validators and exchanges on the specific path. The minting vulnerability fix has been activated, and a complete list of attacker wallets will be announced soon.Previously, the number of ONE tokens abnormally minted on the Harmony network had exceeded 30 trillion, involving 6 abnormal blocks.

The number of registered users on the Zhipu MaaS open platform (i.e., API users) has approached 7 million, an increase of about 2 million compared to early July, including 23,000 enterprise customers. The user count for the developer product ZCode, which competes with Codex, surpassed one million within one month of its launch.Since the beginning of this year, Zhipu's ARR has grown 15 times. It is understood that after the release of new models by Kimi and Alibaba, Zhipu's ARR growth rate has not been affected. Some investors have revealed that the current ARR has reached $2 billion, but Zhipu's official stance has denied this, with people close to the company indicating that the actual figure should be higher. On July 21, it was reported that Zhipu has built a domestic AI computing power infrastructure with a scale of 1GW. It is understood that more than 50,000 domestic computing chips have been activated to alleviate the growing inference demand. On July 31, Zhipu's long-term Coding Plan, which had significantly increased in price, was opened for purchase.

According to Whale Alert monitoring, an address holding 500 BTC was activated after being dormant for 12.7 years. These bitcoins are currently worth $31,315,572, whereas in 2013 they were only worth $507,500.

According to Jinshi reports, the Korean Exchange has activated the circuit breaker mechanism for the KOSDAQ index, suspending trading for 20 minutes.

Zcash activated the Ironwood NU6.3 network upgrade at block height 3,428,143, launching a new shielded pool to enhance network security and allow for the independent verification of ZEC circulating supply.After the upgrade, the original Orchard pool was restricted, and new funds are not allowed to enter. Existing funds must be migrated out through a turnstile before re-entering Ironwood, ensuring at the protocol level that pool expenditures do not exceed verifiable income. Ironwood is based on a revised protocol that has been formally verified and independently audited, aimed at preventing similar risks to the previous Orchard declarative vulnerabilities. Wallets supporting Ironwood (such as Zodl 3.8.0) have provided migration paths, allowing users to transfer funds from Orchard to the new pool without changing addresses.

Uniswap founder Hayden posted on the X platform, stating that many people have not noticed that the Uniswap protocol fees have been activated and UNI has been burned. He continues to receive replies believing that the protocol fees have not been activated.Currently, there are 3 governance proposals being voted on: 1) Robinhood Chain fees (v2/v3); 2) v4 fees; 3) fee bridge cleanup on xlayer, ava, megaeth, sonium.

Zcash core developer Sean Bowe posted on the X platform that the block height for the Zcash Ironwood mainnet activation has been determined and marked. All major organizations have committed to activating the NU6.3 upgrade at block height 3,428,143, expected to occur at 8 PM Beijing time on July 28.According to previous news, this upgrade stems from the earlier Orchard pool vulnerability—this vulnerability could allow attackers to mint an unlimited amount of counterfeit ZEC, and due to the privacy attributes of the Orchard pool, the team could not determine whether any counterfeit ZEC was minted before the vulnerability was patched. The Ironwood upgrade will implement two core measures: first, it will introduce a new privacy pool using the Orchard protocol, while the old pool will be gradually phased out; second, it will add a control flag in the zero-knowledge proof circuit, which, when enabled, can disable the function of transferring to other users in the pool while retaining the change feature.

According to official documentation, Base plans to activate the B20 token standard on the mainnet at 2:00 (UTC+8) on July 9. B20 is a superset of ERC-20, running as a native precompiled program on Base, which allows for lower transfer costs and higher throughput while maintaining full compatibility with ERC-20.Functions such as roles, supply caps, pausing, strategy gating, memo, and permit are all built into the chain. The standard ERC-20 leaves these logics for users to build, audit, and maintain themselves. With B20, developers only need to call the singleton B20 Factory to create a fully configured token in a single transaction.

Base Senior Developer Advocate Jon Roethke tweeted that the B20 token standard is expected to activate on the Base mainnet on June 27 at 2:00. After the activation of the Base Beryl upgrade, the activation registry may take up to about 1 hour to be fully enabled.B20 is a new native token standard introduced with the Base Beryl upgrade, compatible with ERC-20, suitable for scenarios such as stablecoins, RWA, and equity-like assets.

Arc announced that the testnet will officially activate the v0.7.2 upgrade on June 18 at 20:00 (Beijing time), bringing new features to the network. The official reminder for testnet node operators is to complete the upgrade before activation to avoid node desynchronization.

The Zcash developers have completed the consensus rule changes for the Ironwood upgrade and plan to activate this upgrade in July. This upgrade will introduce a new privacy transaction pool based on the Orchard protocol to replace the old Orchard pool, and adjustments will be made to ensure that the circulating supply of ZEC remains constrained.According to the developers' plan, Ironwood will introduce a "flag" mechanism between the old and new Orchard pools, restricting the old pool from receiving new transactions while allowing for change generation as a privacy protection measure. After the upgrade is activated, the old Orchard pool will be prohibited from receiving new deposits, and wallets will route new transactions to the new pool.The developers stated that this design combines the existing turnstile mechanism to ensure that the circulating supply of ZEC cannot be infinitely minted and allows users to migrate their funds to the new pool to reduce potential risks.

Core contributors of the Zcash ecosystem, ZODL, announced that they are collaborating with Tachyon, Valar Group, Zcash Foundation, and Shielded Labs to propose a new network upgrade plan and privacy pool called Ironwood.Ironwood will be built on the existing Orchard protocol and will further enhance security through formal verification and additional independent audits.

The KOSPI index in South Korea has fallen by 5%, with Samsung down 6.5% and SK Hynix down over 8%. Nasdaq futures are down nearly 1%, and large chip stocks are broadly down in after-hours trading.The Korea Exchange has activated the KOSPI circuit breaker due to a 5% drop in KOSPI 200 futures, pausing programmatic trading for 5 minutes.

According to the Tasnim News Agency, Iran and the resistance front have decided to fully block the Strait of Hormuz. As a countermeasure, other fronts may also be activated, including the Strait of Mandeb.Negotiations will not take place until Iran's demands to stop Israeli actions in Lebanon and Gaza are met.Iranian officials have demanded that Israel immediately cease its military operations in Gaza and Lebanon. Iran has also requested that Israel fully withdraw from the areas it occupies in Lebanon before negotiations can resume.

Base announced that its first independent network upgrade, Base Azul, has gone live on the testnet, with the target mainnet activation date set for May 13, 2026. This upgrade is the first network-level upgrade for Base independent of the OP Stack.The official statement indicates that Azul will enhance security, performance, and developer experience in three areas: Base will enable a multi-proof mechanism through Azul, base-reth-node will become its sole execution client, and it will adopt the latest execution layer specification (Osaka) to keep Base aligned with Ethereum. Users do not need to take any action for this upgrade.
