Solana reduced slot time to 350 ms

Solana has successfully implemented the first stage of its plan to reduce slot times, lowering the target from 400ms to 350ms in mainnet epoch 1020. This 12.5% reduction is part of the approved SIMD-0525 upgrade, the first of four planned steps to ultimately achieve a 200ms slot time. The change, activated by validators on the Agave v4.2 client, aims to accelerate transaction confirmations and improve network resilience. Future reductions to 300ms, 250ms, and finally 200ms will each be activated in subsequent epochs, with the upgrade schedule allowing for a pause if missed block rates increase. Following the update, the network's average slot time was approximately 366-370ms. The SOL token price reacted positively, gaining nearly 4.5% to approach $95. The article also notes a recent incident where Solana neared a transaction finality halt due to multiple validator outages.

Arbitrum Activates ArbOS 61 Elara With Optional Orbit Compliance Filters

Arbitrum has activated the ArbOS 61 "Elara" upgrade, introducing new tooling for its Orbit chains. The key addition is an optional protocol-level compliance filtering feature, designed for private or enterprise Orbit deployments to meet regulatory needs, and explicitly not for the public Arbitrum One or Nova networks. The upgrade also expands the Stylus contract size limit from 24 KB to 96 KB, providing developers greater flexibility for building more complex applications in languages like Rust and C++. This move underscores Arbitrum's evolution beyond a single L2 into a broader infrastructure stack, balancing enterprise customization with the open ethos of its public ecosystems.

Besu Discloses Five CertiK-Identified Vulnerabilities Fixed in Latest Security Update

Ethereum client Besu has detailed five security vulnerabilities, ranging from Minor to Major severity, identified by blockchain security firm CertiK. All issues were fixed in the patched version 26.7.1, released on July 27. The vulnerabilities involved block-announcement processing, future-height consensus proposal buffering, WebSocket subscriptions, and JSON-RPC filter creation, which could under certain configurations exhaust node memory or thread capacity, affecting availability or consensus. CertiK discovered the vulnerabilities through independent adversarial testing on a private multi-node network. The 26.7.1 update introduced new configurable controls, including limits on active JSON-RPC filters and WebSocket subscriptions, along with a filter timeout. Besu urged node operators to upgrade promptly. Technical details were withheld until August 14 to provide a responsible disclosure window. The public security advisories now provide full remediation details.

Solana cuts blockchain slot time to 350 milliseconds

Solana has reduced its blockchain slot time to 350 milliseconds, the first reduction since the network's launch. According to Solana Foundation VP of Technology Jacob Creech, this marks a "new era" with a next target of 300ms. Average slot times are currently 360ms, down from the original 400ms target. The reduction is part of a broader plan to eventually cut slot times to 200ms to improve network latency and confirmation speed. This initial cut is the first of four planned 50ms reductions. The changes, formalized in the approved SIMD-0525 proposal, are slated for implementation in the upcoming Agave v4.2 validator client, though the schedule remains tentative.

Solana reduced network slot time to 350 milliseconds

Solana has reduced its network slot time to 350 milliseconds, a first since the network's launch, announced Jacob Crick, VP of Engineering at Solana Foundation. He stated the next target is 300 ms. Prior to this change, the average slot time was 360 ms, already below the network's original 400 ms target. This is part of a broader plan, introduced in June, to progressively cut the slot time from 400 ms to 200 ms. The goal is to improve network responsiveness and accelerate transaction confirmations. The plan involves a total of four 50-ms reductions. These changes are scheduled to be implemented on the mainnet with the release of the Agave v4.2 validator client from Anza, although the timeline is tentative. The underlying proposal for the slot time reduction, SIMD-0525, was approved and incorporated into the code on May 14.

Cardano Network Activity Increased by 33%

Cardano network activity has surged, with transaction counts and developer commits showing significant growth. Since its 2017 launch, the Cardano blockchain has processed approximately 123.02 million transactions. Developer activity is also high, with over 303,000 recorded code commits, indicating ongoing protocol improvements. Data from Chainspect notes a nearly 48% single-day jump in activity, with over 24,000 transactions processed. For comparison, Polkadot leads in developer commits (over 701,000), followed by Ethereum (520,000+), Arbitrum (200,000), and Optimism (182,000). Cardano's Total Value Locked (TVL) increased by 6.05% in 24 hours to $58.01 million, while weekly trading volume on its DEXs rose 22.42% to $9.15 million. Concurrently, ADA's price increased by 13% to $0.2139, with its market cap reaching $7.8 billion and daily trading volume up 52% to $857.6 million. Developers have announced the roadmap for the Dijkstra upgrade, planned in two phases: first deploying Ouroboros Linear Leios (CIP-164) to increase network throughput, followed by Ouroboros Peras (CIP-140) to accelerate transaction processing.

MANTRA Chain Freezes Operations Following Undisclosed Network Incident

MANTRA Chain has suspended all network operations as of August 21 following an undisclosed incident, halting transactions, validators, bridges, and public endpoints. The cause—whether security, configuration, or technical—remains unexplained. This unprecedented freeze occurs just three days after the launch of the MANTRA Zone upgrade, which introduced a new EVM interface. Notably, the network previously remained operational during a significant OM token crash in 2025. The suspension coincides with the pending acquisition of MANTRA Chain by Inveniam Capital Partners, expected to conclude in Q3 2026. The UAE-regulated chain has not disclosed investigation details or a recovery timeline, leaving users unable to transact or move assets via bridges.

Cardano Foundation Drafts Dijkstra Upgrade For Smart Contract Execution

The Cardano Foundation has released a draft Cardano Improvement Proposal (CIP) called "Dijkstra," which proposes changes to enhance smart contract execution pathways and computational efficiency on the network. The proposal is currently in the discussion phase and is not active on the Cardano mainnet; it must progress through community review and refinement before potential implementation. Dijkstra addresses a core long-term challenge for Cardano: improving developer experience and smart contract performance without compromising its methodical, research-driven design philosophy. Enhanced execution efficiency could reduce computational friction, enabling developers to build more scalable and complex decentralized applications (dApps). This is seen as crucial for Cardano's competitiveness in a crowded smart contract market that includes rivals like Ethereum, Solana, and Avalanche. The publication of the CIP draft marks the start of a community evaluation process. Developers will assess its technical merits, potential trade-offs, and alignment with Cardano's broader roadmap. While the outcome is not guaranteed, the proposal signals ongoing work to strengthen Cardano's application layer for the future. The article emphasizes that the technical development story holds more significance than short-term market price movements.

Ethereum Foundation warns some tools may break with Glamsterdam upgrade

The Ethereum Foundation (EF) warns that the upcoming Glamsterdam upgrade, which introduces significant gas-model changes via EIP-8037, may cause some wallets, indexers, and gas estimators to break. Tools relying on a hardcoded maximum gas limit must be updated, as the changes separate state-gas costs for operations that create new state. While a standard ETH transfer to an existing account remains 21,000 gas, sending to a new account incurs an additional charge. Developers are urged to test their software on the Plataberget testnet. The upgrade also includes enshrined proposer-builder separation, block-level access lists, and increased contract and initialization-code size limits.
