On October 8, the XRP Ledger activated the PermissionDelegationV1_1 feature, allowing account owners to authorize other accounts to perform specific tasks without relinquishing control of the account's master key. According to the monitoring site XRPL Dashboard, such upgrades require over 80% support from trusted validators for two consecutive weeks; based on the current 35 validators, at least 29 must support it. The countdown for this feature was reset in September due to the support rate falling below the threshold.This feature allows enterprises to split permissions by function. Stablecoin issuers can authorize compliant accounts to approve new customers while keeping the master key offline. Authorized accounts use their own keys to sign and can only perform the granted operations; owners can change or revoke these permissions at any time. Each authorized account can receive up to 10 permissions, which limit the types of operations they can perform, rather than automatically setting spending limits. Banks have previously separated payment and compliance responsibilities at the employee level, and this upgrade enforces such division at the ledger level.According to a report shared by Evernorth, a subsidiary of XRP Treasury, the network held an average of $3.72 billion in tokenized assets and $539 million in Ripple's RLUSD stablecoin in the second quarter, totaling approximately $4.26 billion. Official guidance advises users not to delegate PaymentBurn permissions before separately fixing activation; this permission is intended for assistants to destroy tokens but, under certain conditions, also allows for the creation of new tokens. This warning pertains to tokens issued on the ledger rather than newly minted XRP.

According to Cointelegraph, Zcash has activated the NU7 network upgrade on the testnet, putting the planned protocol changes into real testing, about a month away from its target mainnet launch. According to data from the Zcash testnet block explorer ZecBlock, the scheduled activation height block 4,465,026 for NU7 was mined on October 4 at 18:21:45 UTC, and Zcash subsequently confirmed on the X platform that NU7 is running on the testnet.NU7 is the next network upgrade for Zcash, which will shorten the network's target block interval from 75 seconds to 25 seconds. This upgrade will also disable version 4 transactions and introduce a network sustainability mechanism that recycles part of the transaction fees for future block rewards. Disabling version 4 transactions also means that if users do not transfer funds before NU7 is fully activated, ZEC stored in the old Sprout shielded pool of Zcash will be unspendable.The Zcash Foundation stated that testnet operators should test NU7 under real conditions using the candidate version, allowing developers to evaluate the upgrade before mainnet activation. Zcash developers plan to make a final decision on mainnet activation and determine the activation height based on the testnet performance on October 20, with a target mainnet activation date of November 5.

According to Whale Alert monitoring, a Bitcoin address that had been dormant for 13.1 years was activated at 17:44. This address contains 801 Bitcoins, worth approximately $6,829,660.

The Polygon Foundation announced on the X platform that the PIP-92 proposal has been officially activated, and the staking rewards for the Polygon Chain will be increased to an expected 7.7%. This incentive will last until December 1, 2026.According to PIP-92, the 27.3 million POL priority fees accumulated by the network will be used to enhance the reward earnings for stakers over the next two months.

The Ethereum Foundation announced that the Ethereum network upgrade Glamsterdam will be activated on the Sepolia testnet on October 6 at 21:53:36 Beijing time, corresponding to epoch 353024 and slot 11296768. The activation date for Hoodi and the mainnet has not yet been determined.Glamsterdam combines the execution layer Amsterdam upgrade and the consensus layer Gloas upgrade. Key changes include the embedded proposer-builder separation and block-level access lists to enhance L1 throughput, as well as adjustments to gas billing to better reflect the costs of execution and state growth. Node operators must update their execution layer and consensus layer clients before activation. Contracts relying on fixed gas assumptions may need to be modified.

The privacy blockchain project Zcash plans to implement the NU7 upgrade, which will stop accepting the fourth version of transactions that spend funds from the Sprout pool after the upgrade. If ZEC is not transferred out before the upgrade, holders may lose the ability to spend the related funds. This proposal will not destroy the Sprout pool funds, and access may be restored in the future, but the proposal warns that funds left in the pool may also become permanently unspendable.Zcash co-founder Zooko Wilcox has forwarded the relevant reminder. The NU7 upgrade is scheduled to activate on the testnet on October 6, and Zcash expects to decide on October 20 whether to activate it on the mainnet as planned on November 5. The upgrade will also reduce the target block time from 75 seconds to 25 seconds and maintain the network halving cycle.

According to Whale Alert monitoring, a dormant address holding 600 BTC (worth 51.15 million USD) has been activated after 14.2 years of inactivity.

The Zcash development team plans to activate the NU7 mainnet upgrade on November 5, after various organizations and engineering teams have reached a consensus on the upgrade content and expected timeline. Zcash developer Sean Bowe stated that the upgrade will be activated on the testnet on October 6. The team plans to finalize the mainnet upgrade and activation block height after evaluating the performance of the NU7 testnet on October 20.The upgrade will shorten the target block interval from 75 seconds to 25 seconds, disable version 4 transactions, and integrate a network sustainability mechanism. The selected network sustainability mechanism will retain the Zcash halving cycle, with the previously removed supply being reintroduced starting February 2031. NU7 does not introduce a new transaction format, resulting in limited impact on wallets, but full nodes, indexers, and block explorers may need adjustments.

According to a report by Christine D. Kim, Ethereum developers confirmed at the ACDC #186 meeting that the Glamsterdam upgrade will be activated on the Sepolia testnet on October 6 at 13:53 UTC. However, there is significant uncertainty regarding this upgrade—currently, the latest private testnet Glamsterdam-Devnet-9 is not stable, and a serious vulnerability has been discovered in the consensus layer that could cause the entire network to stop producing blocks. The execution layer EIP-8037 also has bugs that need to be fixed.Developers will launch Devnet-10 in the coming weeks, and if Devnet-10 remains unstable, the Sepolia upgrade date may be postponed. The activation schedule for the Hoodi testnet and mainnet is currently undetermined, and whether the goal of launching the mainnet by the end of the year can be achieved remains uncertain.

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.
