The first Blob-Parameter-Only (BPO) fork went live on Ethereum mainnet on Tuesday morning at block 23975796. The lightweight BPO upgrade, introduced by EIP-7892, solely adjusted two parameters: increasing the blob target from 6 to 10 and raising the maximum blob limit from 9 to 15. This expansion of blob capacity is a key adjustment for reducing Layer 2 transaction costs. BPO forks are designed to balance the bandwidth constraints of solo stakers with the growing data availability needs of Layer 2 solutions, enabling more scalable blob transactions. The next BPO fork is scheduled for January 7th, which will further raise the blob target to 14 and the maximum limit to 21.

ADI Chain, an EVM L2 network powered by GPU computing, is now live on mainnet. The launch also includes its native gas token, ADI. ADI Chain is built on ZKsync’s Elastic Network, leveraging Airbender, ZKsync’s RISC-V–based zkVM. Airbender is designed to support future cross-chain and modular interoperability. Backed by leading UAE institutions and regulated by the UAE Central Bank, ADI Chain will host the first Dirham-backed stablecoin developed by First Abu Dhabi Bank and IHC. ADI Chain aims to serve as a compliance-ready platform designed for institutional and real-world asset (RWA) digital infrastructure.

1inch introduced Aqua Protocol, a shared liquidity layer designed to solve capital fragmentation and unlock dormant value in DeFi. The protocol allows a user's assets to power multiple DeFi strategies simultaneously from a single wallet, creating a multiplier effect for liquidity and shifting the focus away from locked liquidity. The protocol is self-custodial, meaning assets remain in the user's wallet, only being pulled and returned in a single, atomic transaction when a trade executes. A developer release, including the SDK and documentation, is now available for experimentation. A full user interface (UI) is scheduled for a public launch in early 2026.

Rainbow announced a public token sale for its $RNBW token on the CoinList platform. The sale is scheduled to go live on December 11, at 5:00 pm UTC, and will be open to both from the US and non-US users. Last week, Rainbow announced a new Class F share class that grants the Rainbow Foundation a 20% equity stake in the company on behalf of all $RNBW token holders. The TGE date is yet to be announced.

BlackRock filed a new Form S-1 with the SEC to gain approval for its iShares Staked Ethereum Trust ETF, which will trade under the ticker ETHB and become the company's fourth iShares crypto ETF. The filing's approval is required before trading of the Staked ETH ETF can begin. Staking yield will be treated as income for the Trust. The new ETF is expected to improve returns for shareholders while simultaneously contributing to the economic security of the Ethereum network. The move follows the successful launch of the iShares Ethereum Trust ETF (ETHA), which began trading in July 2024 and currently holds over $11 billion in ETH.

Aztec Network raised 19,476 ETH from its token sale, leveraging Uniswap's Continuous Clearing Auction (CCA) mechanism. The CCA enables automatic liquidity bootstrapping by selling tokens block-by-block, fulfilling orders at multiple clearing prices. Over 16,741 users participated in the sale. Participants can now claim their $AZTEC tokens, which will remain non-transferable until an onchain governance vote, scheduled potentially as early as February 11th, 2026. Users with over 200k tokens can now stake their allocation to secure the network. Aztec Network is a privacy-preserving Layer 2 for private smart contract execution.

ZKsync announced the planned deprecation of its original protocol version, ZKsync Lite, in 2026. Launched in June 2020, ZKsync Lite served as a proof-of-concept that validated key ideas for zero-knowledge (ZK) systems, leading to its current ZKSync Era network. No immediate action is required by users. ZKsync will release a detailed migration plan in the coming year. ZKsync says funds on ZKsync Lite will remain safe and withdrawals to L1 will continue to function throughout the process. The team is focusing on the ZKsync Era network, including the ZK Stack and Prividiums. ZKsync Era currently holds over $480 million in total value secured (TVS) as the 7th largest rollup.

OKX migrated X Layer, it’s native L2 network, from Polygon's Chain Development Kit (CDK) to Optimism’s OP Stack. X Layer aims to provide 5,000 TPS for real-time markets, near-zero slippage for DEX trades, full EVM compatibility, and access to OKX and L2 liquidity. OKX is integrating bridging to X Layer in its self-custodial wallet. The exchange aims to connect its user base of 50 million with the Ethereum ecosystem. With over $25 billion in user assets, OKX currently ranks as a top 5 centralized crypto exchange with $1.9 billion 24-hour trading volume.

L2Beat researcher donnoh.eth published his thoughts to reducing the withdrawal window for Stage 1 Optimistic Rollups from seven days to potentially one day, within the context of the Ethereum L2 Stages Framework. Optimistic rollups currently use a 7-day challenge period to protect bridged funds primarily against a strong censorship attack. The rollup framework dictates that Stage 2 rollups must maintain this 7-day period to fully inherit Ethereum security guarantees. The concern with a shorter period for Stage 1 is the increased vulnerability to soft censorship attacks. In economic censorship attacks, defenders must spend funds on priority tips that are not reimbursed. Donnoh.eth says that the next step for reducing the withdrawal window is to agree on a reasonable defender advantage to require.

ethPandaOps launched a live custody monitoring tool, powered by the dasmon engine, for Peer Data Availability Sampling (DAS) introduced in Fusaka. Fusaka moved Ethereum's Data Availability (DA) from full replication to a sharded architecture via PeerDAS, where individual nodes only store a subset of the data. The tool aims to ensure the network collectively upholds DA guarantees by making Ethereum's new data availability layer observable and verifiable, giving operators, researchers, and users confidence in the network's guarantees. ethPandaOps is an Ethereum DevOps team that provides resources for testing protocol upgrades.

The Ethereum Everywhere team, an Ethereum Foundation team dedicated to amplifying and connecting communities and events globally, is launching an Ethereum Community Hub in Lagos, Nigeria. Located at Web3bridge Africa, the hub will serve as a co-working space and central gathering point for builders, researchers, creators, and artists developing within the Ethereum ecosystem. The hub will host a launch event on December 11, 2025. Two other Ethereum hubs are already live in London and Berlin.
