Who Pays Ethereum When Rollups Move Transactions Off-Chain?

AI-summarised brief · reviewed before publication

Ethereum rollups such as Arbitrum, Base and Optimism process most user transactions but they still rely on Layer 1 for data availability, settlement and security. Users pay fees to the rollup, which include a Layer 2 execution component and a charge for publishing transaction data to Ethereum. Rollup operators collect these fees and later settle batches of transactions on L1, paying Ethereum in ETH. The settlement uses EIP‑4844 blobs, whose fee market lowers data‑storage costs; historically over 90 % of rollup costs were for Ethereum data storage. Zero‑knowledge rollups add the expense of generating and verifying cryptographic proofs, consuming 500 k gas per batch. By aggregating transactions, rollups keep user fees low while Ethereum continues to earn fees from batch settlement and data storage.

💡 Why It Matters

· Ethereum’s ability to monetize cheap blob storage enables rollups to slash fees dramatically, paving the way for scaling to hundreds of thousands of transactions per second.

How ants are cashing in on the fight against money laundering

A study from Charles Darwin University proposes a swarm‑based AI system, inspired by ant colonies, to detect blockchain money laundering. The model assigns five specialized agents—each performing a distinct task such as flow analysis, relationship modeling, and anomaly tracking—to create a decentralized, adaptive detection framework. By combining multi‑agent AI with blockchain, the approach aims to improve accuracy, explainability, and auditability over traditional rule‑based systems. Researchers emphasize refining inter‑agent protocols and integrating the framework with compliance tools to enhance jurisdictional interoperability and regulatory compliance.

💡 The swarm‑based design offers a scalable, transparent alternative to static AML systems, potentially tightening oversight of rapidly evolving crypto‑financing channels.

ShardLab and Indonesia’s EKRAF Expand Blockchain Talent Partnership as Protocol Camp Cohort…

ShardLab, the blockchain arm of Hashed, concluded Protocol Camp Cohort 9 with a final demo at Melasti Beach, Bali, on August 21, 2026. The 12‑week builder bootcamp, part of a new Memorandum of Understanding with Indonesia’s Ministry of Creative Economy (EKRAF), selected six Indonesian participants through an international screening process. The MoU aims to cultivate blockchain talent across Southeast Asia, supporting Indonesia’s broader strategy to develop national capacity in decentralized technologies and digital assets. The program follows a successful partnership that has already produced projects such as BeBridge’s AI hackathon win and DollarParking’s stablecoin‑backed equity app.

💡 The collaboration signals Indonesia’s shift from a passive market to an active creator of blockchain solutions, positioning local talent to monetize intellectual property on a global scale.

Bithumb Temporarily Halts ONT, ONG, and MBL Transactions for Ontology Network Upgrade

South Korean exchange Bithumb halted deposits and withdrawals for Ontology tokens ONT, ONG, and MBL beginning 10:00 a.m. UTC on August 20 to support a scheduled Ontology network upgrade. The pause is intended to prevent transaction errors during the protocol change, a common practice when blockchains undergo hard forks or major updates. Trading of these tokens remains possible, but network‑dependent functions are disabled until the upgrade completes. Bithumb has not set a final end time, but similar maintenance windows typically last a few hours. Users are advised to monitor official announcements for resumption details.

💡 The suspension underscores how exchange‑level safeguards protect user assets during critical blockchain upgrades, preventing potential loss or stuck balances that could arise from incompatible transactions.

JCB, in Collaboration with Digital Garage, to Conduct a Proof of Concept…

JCB Co., Ltd., Digital Garage, Inc., and Lawson, Inc. have signed a Basic Agreement to pilot stablecoin payments in Lawson stores. The proof‑of‑concept will test the CPM (Consumer‑Presented Mode) method, where shoppers scan a barcode linking to a USDC wallet on their phone. JCB will supply the stablecoin payment platform and handle settlement, Digital Garage will provide payment APIs and backend support, and Lawson will host the PoC in its retail outlets. The trial aims to demonstrate the feasibility and convenience of USDC‑based in‑store transactions for inbound visitors to Japan.

💡 By validating stablecoin payments in a high‑traffic retail environment, the project could streamline foreign‑currency transactions for tourists, reduce settlement friction for merchants, and position Japan as a leader in crypto‑enabled commerce.

Web3 Platform Mixin Network Hit by $200m Crypto Hack

Hong Kong‑based decentralized finance project Mixin Network disclosed a cyber‑attack that compromised its cloud service provider’s database on September 23, 2023, resulting in the loss of roughly $200 million in cryptocurrency. The breach forced the platform to suspend deposit and withdrawal services while transfers remained operational, and Mixin enlisted Google and blockchain security firm SlowMist to investigate. Founder Feng Xiaodon addressed users in a live Mandarin briefing on September 25, outlining remediation steps, and the project later reported a $30 million drop in total value locked, according to DeFi Llama. Launched in 2017, Mixin’s XIN token supports cross‑chain transactions for about 10,000 DApps. The incident ranks as the fifth‑largest crypto hack outside exchanges, trailing incidents such as Ronin, Poly Network, BNB Bridge and Wormhole.

💡 The hack exposes the vulnerability of “decentralized” platforms that still depend on centralized cloud infrastructure, challenging the core security premise of Web3.
