Two wallets tied to hackers bought Ether on July 12, according to on-chain monitor Ember. One hacker, identified as having stolen funds from Coinbase users, spent 7.378 million DAI early in the day to purchase 4,049.7 ETH at an average price of $1,822. A second address, which had received ETH from Tornado Cash in November last year, used 4.34 million DAI two hours before the report to buy back 2,405 ETH at an average price of $1,804. The combined purchase totaled 11.718 million DAI. The activity was flagged by Ember and cited by BlockBeats in a market update published on July 12. No other transaction details were disclosed in the report.

Ryan Berckmans argues that Robinhood Chain does not weaken the case for Ethereum. In his view, it does the opposite: it shows how a company building a real onchain business can choose Ethereum as the base layer while using an Ethereum Layer 2 for speed, customization and operational control. The article responds to the claim that serious operating companies are no longer interested in L1 or L2 infrastructure, using Robinhood as a counterexample. Berckmans says Robinhood first issued tokenized stocks on Arbitrum One, then moved to a dedicated chain built with Arbitrum technology. He describes Robinhood Chain as an Ethereum L2 that uses Ethereum blobs for data availability, ETH as the native gas token, and Ethereum for settlement and security. In that framing, Robinhood did not reject existing L1 and L2 infrastructure; it chose not to share its execution environment while still anchoring to Ethereum. The article places that decision in a broader shift across crypto. Berckmans argues that earlier crypto markets were dominated by token-centric projects, while the next phase will be shaped more by businesses focused on customers, products, cash flow and distribution. He says that changes in regulation, including the GENIUS Act in the United States and MiCA in Europe, have opened more room for large institutions to test stablecoins, tokenization and onchain transactions. As that buyer mix changes, he expects demand to concentrate around Ethereum’s split model: L1 for settlement, neutrality and liquidity, and L2 for tailored execution.

Robinhood Chain recorded $877.6 million in decentralized exchange trading volume over the past 24 hours, according to DefiLlama data cited by BlockBeats on July 12. That placed the network second across all chains during the period. Solana ranked first with $1.133 billion in 24-hour DEX volume, while Ethereum mainnet came in third at $778 million. The figures reflect a snapshot of recent on-chain trading activity across major blockchain networks and show Robinhood Chain ahead of Ethereum mainnet for the period covered in the data. No additional details on specific protocols or token pairs were provided in the source.

Two addresses tied to illicit crypto flows bought back a combined 6,454.7 ETH on July 12, according to on-chain analyst Ember, as cited by Odaily. One address, identified as a hacker wallet that stole funds from Coinbase users, spent 7.378 million DAI in the early hours of the day to purchase 4,049.7 ETH at $1,822. The second address, which had received ETH from Tornado Cash in November last year, spent another 4.34 million DAI about two hours before the report to acquire 2,405 ETH at $1,804. Ember also said that this second address had previously moved out 4,978 ETH and swapped it for 16.294 million DAI at a price of $3,273. The two transactions brought the day’s combined DAI outlay to 11.718 million and total ETH purchased to 6,454.7.

Bitfufu produced 125 BTC in June, with 70 BTC coming from self-mining operations and 55 BTC generated through its cloud mining service, according to a report cited by Odaily. The company’s average daily output dropped to 4.2 BTC from 5.7 BTC in May. At the same time, its total managed power capacity declined from 346 MW in the previous month to 273 MW. Despite the lower managed power capacity, Bitfufu said its proprietary hashrate rose 9.4% to 3.5 EH/s. The increase was linked to the purchase and deployment of 1,200 S21 XP mining rigs in June. The company also signed an agreement to buy and deploy another 2,000 S21 XP machines in July. As of June 30, 2026, Bitfufu held 1,671 BTC, down from 1,855 BTC at the end of May. Its average fleet efficiency was 17.9 J/TH in June, compared with 17.8 J/TH in May. By the end of the period, third-party suppliers and hosted clients accounted for 11.8 EH/s of the company’s 15.3 EH/s in managed hashrate. The figures were reported by Bitcoin.com News.

Polymarket generated more than $11 million in revenue this week, marking a new all-time high, according to data from DefiLlama cited by BlockBeats on July 12. The protocol’s cumulative revenue has also climbed past $97 million. The update points to a new peak in weekly earnings for the prediction market platform, based on the figures referenced in the report. No additional operating details were provided in the source brief.

OpenAI researcher Ethan Knight said on X on July 12 that GPT-5.6 Sol Ultra generated a proof paper and prompting setup for the cycle double cover conjecture, a well-known unsolved problem in graph theory. According to Knight, the model completed the result in about one hour, using up to 64 parallel sub-agents and without internet search. OpenAI’s public paper is three pages long. It first reduces the problem to cubic regular graphs, then uses the 8-flow theorem and GF(3) labels, and applies linear algebra to build a structure in which each edge is contained in exactly two cycles. The claim has not been published in an academic journal, has not gone through peer review, and has not been checked by formal verification systems such as Lean or Coq. Thomas Bloom, a mathematician at the University of Manchester in the UK, called the proof “very impressive” while also saying the references were not sufficient. The report was cited by ZDNet Korea Semiconductor and carried by Odaily.

Shenzhen-based Yunbao Smart has had its application for a ChiNext IPO accepted by the Shenzhen Stock Exchange, putting the chip startup on track to pursue the label of China’s first listed DPU company. Founded in August 2020 by Stanford PhD Xiao Qiyang, the company focuses on data processing units, a segment that gained attention after Nvidia introduced the DPU concept and Jensen Huang outlined the “CPU+DPU+GPU” architecture. According to the prospectus cited in the report, Yunbao Smart developed what it describes as China’s first high-performance, general-purpose programmable DPU SoC chip, with network bandwidth of 400 Gbps, four times the performance of traditional solutions, and power consumption cut by more than 50%. The company said it moved from FPGA verification to 6nm SoC mass production in four years. Financially, revenue rose from RMB 170,000 in 2023 to RMB 36.35 million in 2024 and RMB 370 million in 2025, while net losses were RMB 667 million, RMB 600 million, and RMB 1.19 billion over the same period. Tencent, which first invested in the angel round and kept backing later financings, held 19.7792% before the IPO through affiliated entities, making it Yunbao Smart’s largest shareholder. The report said the company’s valuation exceeded RMB 14 billion after a funding round in late November 2025.
