On October 2, at 11:30 AM Eastern Time, the Arbitrum Security Committee executed an emergency upgrade on Arbitrum One and Nova, suspending the activation of all new Stylus contracts on both chains, while adding a protective mechanism against BoLD single-step proofs in the dispute system of Arbitrum One. The Arbitrum Foundation stated that this action is part of ongoing proactive security measures aimed at protecting the security and integrity of the network.Stylus allows developers to write smart contracts using languages such as Rust and C++, while maintaining compatibility with the Ethereum Virtual Machine, with its programs compiled into WebAssembly format. This suspension primarily targets manually written WASM programs that do not use the standard Stylus compiler toolchain and have not yet been patched by the current version of ArbOS. The Security Committee increased the gas required for activation to the theoretical maximum by calling ArbOwner.setWasmActivationGas(2^64 - 1), making new activations economically unfeasible. Activated Stylus contracts are unaffected and can continue to execute and renew, and the deployment and execution of Solidity contracts are also unrestricted.The newly added BoLD protection allows anyone to pause the settlement from Arbitrum One to Ethereum when two conflicting and accepted answers appear in the same dispute step, which may delay unconfirmed withdrawals to allow the Security Committee to deploy fixes. Officials pointed out that the currently discovered Stylus-related vulnerabilities mainly affect the activity of the chain, such as denial-of-service attacks, and do not jeopardize user funds.

The Batch V1.1 upgrade for the XRP Ledger is just one vote away from initiating the activation process. The RippleX team has fixed 11 software defects in the latest review. The Batch feature allows users to combine up to eight related transactions into a single operation, ensuring that both parties complete the transfer simultaneously when two people exchange tokens, thus avoiding the situation where one party pays while the other fails.In Tuesday's snapshot, the upgrade received support from 27 out of 35 trusted validators, accounting for approximately 77%, while changes to the XRP Ledger require an 80% support rate. Therefore, currently, one validator's vote can determine success or failure, and obtaining one more vote will initiate a two-week activation countdown. The support rate must remain above this threshold for 14 days, during which validators can change their votes.Previously, researchers discovered vulnerabilities in the original Batch proposal, allowing attackers to initiate transactions using others' accounts without authorization under specific conditions; this version was not deployed on the mainnet. The new version was released with xrpld 3.3.0 on August 6, and the latest review found 11 issues related to signatures, authorization checks, and server crashes. Among these, a serious vulnerability rated by the security company Common Prefix could allow attackers to reuse user signature permissions to execute transactions beyond expectations. RippleX stated that the review involved four senior engineers, audits from Halborn and Common Prefix, public security competitions, and automated testing, and mentioned that commercial projects using Batch have been signed or are in development.

According to SolanaFloor, Jump Crypto's Firedancer team will stop supporting the Solana transitional validator client Frankendancer after Alpenglow is activated on the Solana mainnet, with the upgrade expected to go live in October with v4.3.The team stated that the decision was made due to the maintenance and security burden, and they will subsequently focus resources on the complete Firedancer client.

Pine Analytics released the Zcash Q3 2026 report. Ironwood was activated on July 28 at block 3,428,143, and within five weeks, holders migrated 87% of their Orchard balance, with the new pool holding 3.84M ZEC as of August 31. The shielded supply increased by 9.9% to 4.86M ZEC, with the shielded ratio rebounding from 26.3% to 28.7%, recovering 440K from the 745K unshielded ZEC in June.The price of ZEC rose from $407 on June 30 to $836 on August 31, an increase of 106%. Grayscale ZCSH converted to a spot ETF, with assets growing from $155 million to $346 million. Mining difficulty rose by 35%, reaching an all-time high, with two corporate miners committing approximately $65 million in hash power. NU7 has no mainnet height yet, and holders will vote until September 14 to decide whether to launch before September 30 with a 25-second block time and smooth issuance; there are still 470K ZEC remaining in Orchard.

The core development team of Solana, Anza, posted on platform X stating that the mainnet Beta transaction V1 will begin activation at epoch 1035, expected around September 15 at 1:20 UTC.The ecosystem team indicated that more time is needed to test and integrate V1 support; V1 is currently live on the development network for integration testing. The computational budget in V1 is set through new transaction configuration settings; the computational budget instructions are still usable in traditional transactions and V0 transactions, but will not take effect in V1; application developers should check the impact of related changes on their applications even if they do not plan to send V1 transactions.

Solana developer Brennan Watt announced on the X platform that the Solana mainnet has activated the first slot time reduction, with the target decreasing from the current 400 milliseconds to 350 milliseconds, which will officially take effect in the 1020th Epoch.Watt pointed out that some SDK constants (such as DEFAULT_MS_PER_SLOT) have not yet been updated to the new values and will be pushed in subsequent versions. The transition period may affect applications that rely on SDK constants matching the mainnet reality, and developers are advised to manually determine whether the functionality is enabled based on Epoch boundaries when it takes effect. Watt explained that the long-term plan is to put these parameters on-chain for client queries, but currently, to launch the reduction feature as soon as possible, this transition period must be endured.

The proposed soft fork BIP-54 (Consensus Cleanup) specification for Bitcoin was completed in May 2026, aimed at fixing four consensus rule boundary issues without adding new Bitcoin features. Wang Chun, co-founder of the digital asset mining pool F2pool, stated that they do not support BIP-54 and mentioned that if the proposal obtains the required majority through the standard BIP-9 process, F2pool will upgrade its mining nodes but will not issue a support signal in advance.BIP-54 has been tested in the Signet-based testing environment Bitcoin Inquisition, and the mining pools MARA and ViaBTC have voluntarily produced compatible coinbase transactions; the formal activation parameters have not yet been determined, and the mainnet voting is still incomplete. Previously, BIP-110, which attempted to restrict certain non-financial data in Bitcoin transactions, did not receive enough support from miners and stalled around block height 961635; BIP-54 does not involve restricting general script functionality.

According to Bitcoin Magazine, the BIP-110 soft fork is about to enter a critical activation phase. The proposal will enter the mandatory signaling phase around August 9, corresponding to block height 961,632, and is expected to lock in at block 963,648 by the end of August, with new transaction rules activated at block 965,664 in early September. BIP-110 adopts a 55% signaling threshold, and its restrictions will be enforced for 52,416 blocks (approximately one year).BIP-110 mainly restricts transaction features such as large data pushes, oversized output scripts, undefined witness versions, and Taproot annexes, but exempts UTXOs created before activation, maintaining compatibility for standard currency use. Analysis indicates that most businesses do not need to take action—businesses that act as value storage or process transactions through third-party payment providers are essentially unaffected. Businesses running their own full nodes can choose whether to switch to BIP-110 nodes. The core risk to be aware of is chain forking. If a fork occurs, miners should choose the branch expected to prevail or pause and wait; exchanges and custodians should increase confirmation requirements, monitor dual chains, and delay final settlements to prevent double spending and false confirmation risks. If there is no fork, no special actions are required.

According to official news, Uniswap Labs has released a temperature check proposal, suggesting the activation of protocol fees in the v4 pool. This proposal follows the rapid governance process previously approved by UNIfication and will directly enter a five-day Snapshot voting period, followed by on-chain voting.Due to the Hook architecture of v4 making fee settings more complex than v2/v3, the proposal has designed the V4 Fee Controller system, which includes two core contracts: V4FeePolicy calculates the fees for any pool based on governance rules, and V4FeeAdapter is responsible for executing governance overrides and collecting fees into TokenJar. Fees are calculated hierarchically based on the family of the pool: first checking the specific trading pair rate set by governance, then the family default rate, and finally the global default rate.This proposal aims to activate fees for three types of pool families across 11 chains including Ethereum, Arbitrum, Base, and BNB Chain: static rate pools without Hooks, CCA pools after continuous liquidation auctions, and aggregator Hook pools. The rates for aggregator Hook pools are adjusted by a 25x multiplier, with a default of 10 bp for non-Base chains (3 bp for stablecoin pairs) and a default of 3 bp for Base chains (1 bp for stablecoin pairs). All fees will flow into each chain's TokenJar, and the amount of UNI burned on L2 and Alt-L1 will be cross-chain bridged to the Ethereum mainnet and sent to the 0xdead address.The Snapshot voting window is from July 7 to July 12, and on-chain voting will start during the week of July 13. Since GovernorBravo limits each proposal to 10 actions, two on-chain votes will be submitted in parallel to cover all chains.

According to Zcash developer Sean Bowe (@ebfull), the Zcash Ironwood network upgrade has made significant progress: all consensus rule changes have been implemented and have entered the audit phase, and the related specifications (ZIPs) have been released and are nearing final status; the testnet activation is scheduled for July 4, and the mainnet activation is expected to be completed around July 21.The team is simultaneously conducting formal verification work to eliminate potential risks regarding supply integrity, and the relevant results will be announced before the mainnet activation. The only impact on users after the upgrade will be the migration process of the old funding pool. There is already sufficient hashing power expressing support for the mainnet upgrade, although some wallets may not be able to complete adaptation in time, but the team has stated that this will not delay the activation, and ample alternative solutions and testnet time will be provided.

According to on-chain analyst Ai Yi's monitoring, the WLFI unlocking activation portal has been open for two weeks. A total of 45.9 billion WLFI has been transferred to the unlocking contract, with a progress of 73.8% and a total value of 2.81 billion USD.The WLFI team and related stakeholders have burned 3.2 billion WLFI, valued at 194 million USD. The current price of WLFI is 0.06137 USD, an increase of 18% compared to the low point at the beginning of the month.

The stablecoin one-stop wallet UU Wallet today announced the launch of the 15-day "UU Travel Season" event. During the event, users who complete their first travel-related purchase using the UU Visa virtual card or physical card will receive a $5 cashback. Supported platforms include major global travel and transportation service providers such as Uber, Grab, Booking.com, Airbnb, and Trip.com.In addition, to lower the access threshold for users, UU Wallet will implement a limited-time policy of waiving the card activation fee for virtual cards during the event. New users can activate and use the card for free after completing real-name authentication, and existing users can also activate their accounts without upfront costs during this period.It is reported that UU Wallet is committed to providing global payment and remittance services centered around stablecoins, and has already launched Visa card and cross-border remittance functions. This event is a core initiative to promote the "daily use of on-chain dollars" and user growth in the second quarter of 2026. In the future, the platform will continue to enhance its product matrix around payment, exchange, and wealth management services related to stablecoins.

According to Whale Alert monitoring, a dormant Bitcoin whale address that has been inactive for 13.7 years has just been activated, containing 2,100 BTC (worth $147 million), which were only valued at $13,685 in 2012.

Aave founder Stani.eth announced on the X platform that Aave has released the Aave V4 Ethereum mainnet activation governance proposal. Aave V4 will introduce a modular architecture, where the liquidity center Liquidity Hubs holds shared liquidity, while Spokes define independent lending environments with governance restrictions. This version is also expected to launch a topology, promotion paths, implementation and control models, as well as an initial asset range for risk parameterization. Once the community reaches a consensus on this proposal, a Snapshot will be submitted for voting.

The decentralized confidential computing project Acurast has announced the ACU token economics. The total supply of ACU tokens is 1 billion, of which 24% will be used for community activation (early computing providers, Cloud Rebellion airdrop, listing incentives, CoinList token issuance), 11.5% will be used as operational funds, 24% will be allocated to the community treasury, 24% will be distributed to the team and advisors, 10% will be used for liquidity, and 6.5% will be allocated to early supporters.

According to records from forkcast org, the 172nd Ethereum Consensus Layer Core Developer Conference (ACDC) mainly discussed: successful activation of BPO2, Blob Target increased to 14, Limit increased to 21; EIP-8070 (Sparse Blob Pool) confirmed to be included in Glamsterdam; the proposal process for the Hegota headline proposal has been opened.

The Ethereum treasury company Bitmine has once again deposited 82,560 ETH into the Ethereum staking system, bringing its total staked ETH amount to 544,064, valued at approximately $1.62 billion at current prices.Due to Bitmine's recent acceleration in staking, the current Ethereum validator queue has increased to about 977,000 ETH, with new validators expected to wait nearly 17 days. The amount of ETH waiting to be withdrawn in the exit queue exceeds 113,000.Ethereum network data shows that over 35.5 million ETH have been staked at this stage, accounting for about 29% of the total supply, with an annualized staking yield close to 2.54%.

Data analyst jpn memelord stated that one major effect of Uniswap enabling the fee switch is that fraudulent liquidity pools (such as honeypots and automated rugs) can disappear overnight, as these pools rely on a protocol fee rate of zero.According to rough estimates, half of the trading volume on Uniswap on Base may belong to such pools. The official unfiltered data shows that the trading volume of Uniswap on Base in 2025 is $208.07 billion, but after adding some filtering criteria, the non-fraudulent trading volume is only $77.38 billion.

ChainCatcher news, according to whale_alert monitoring, a wallet address that has been dormant for over 14 years has just been activated, containing 4,000 BTC (worth $442 million), which were valued at only $67,724 in 2011.
