• Tornado Cash Proof of Association (PoA) tool.

• Bhutan launches its digital identity system.

• ZKsync Prividium Breakthrough Initiative.

• BitMine now holds 3 million ETH.

0xbow, the developers of the Privacy Pools protocol, introduced Tornado Cash Proof of Association (PoA), a tool that allows Tornado Cash users to cryptographically prove their withdrawals aren’t linked to illicit addresses without compromising privacy. The system generates a ZK proof that checks a withdrawal against a curated blacklist. Users simply enter their note and withdrawal address; all computation happens locally, and no connection between deposit and withdrawal addresses is revealed. The PoA aims to end suspicion toward Tornado Cash users by maintaining a public PoA Registry that marks verified addresses.

Bhutan, a small Buddhist kingdom on the eastern edge of the Himalayas, launched its national digital identity system on Ethereum, becoming the first country to do so. Aya Miyaguchi, President of the Ethereum Foundation, and Ethereum creator Vitalik Buterin, attended the launch ceremony alongside Bhutanese leadership. Known for its Gross National Happiness framework, Bhutan aims to align digital innovation with citizen wellbeing. The Bhutan National Digital Identity (BNDI) system is already fully operational, with credentials for all 700,000+ citizens expected to migrate by Q1 2026. The initiative is a collaborative effort among the NDI team, GovTech, and Ethereum community contributors.

ZKsync unveiled the Prividium Breakthrough Initiative, aimed at bringing blockchain infrastructure to global institutions and creating an interconnected global financial network. The effort is backed by Citi, Deutsche Bank, Mastercard, and over 30 other partners. It addresses the challenges of balancing privacy, security, interoperability, and speed. Unlike existing infrastructure, Prividiums are permissioned, private Layer 2 networks anchored to Ethereum and secured by zero-knowledge proofs. They offer up to 15,000 transactions per second throughput with one-second latency.

BitMine Immersion Technologies Inc. now holds over 3 million ETH, worth approximately $12.8 billion, representing more than 2.5% of Ethereum’s total supply. The milestone marks the halfway point toward BitMine’s goal of owning 5% of the ETH circulating supply. The company recently acquired 202,037 ETH during last week’s crypto market flash crash. Altogether, Digital Asset Treasury companies now hold nearly 6 million ETH, approaching the 6.9 million ETH held by ETFs.

• $19b in crypto liquidations

• Aave executes $180m in liquidations.

• A whale nets $192 million in profits.

• Keyring launches a donation vault.

The cryptocurrency market suffered a historic $19 billion liquidation event on Friday, October 10, 2025, marking the largest in its history, surpassing the Covid, FTX, and Luna crashes. Long positions accounted for $16.6 billion, with shorts losing $2.4 billion, including $5.5 billion wiped out in a single hour. The crash intensified after President Trump announced 100% tariffs on Chinese imports effective November 1, causing Bitcoin and Ethereum to plummet about 12%. Bitcoin fell by nearly $20,000 amid the flash crash. Altcoins faced even more severe losses, with some seeing extreme down wicks due to thin liquidity.

Roughly thirty minutes before President Trump’s October 10, 2025, announcement of 100% tariffs on Chinese imports, a newly created Hyperliquid account opened massive short positions on BTC and ETH with 8-12x leverage. The trades, executed on the decentralized perps exchange, netted $192 million in profits within hours amid the crypto market crash. The precise timing of the trade has sparked allegations of insider trading.

Aave, the leading DeFi protocol with over $40 billion in TVL, processed $180 million in liquidations in a one-hour period during the historic crypto market crash triggered by Trump’s 100% tariff announcement on Chinese imports. Founder Stani Kulechov praised Aave’s flawless performance, marking the largest single-day stress test for the DeFi protocol. The AAVE token itself plummeted 64% in the flash crash, but has mostly recovered since.

The Ethereum Foundation’s Funding Coordination Team, in partnership with Keyring Network, launched a donation initiative to support the legal defense of Tornado Cash developers Roman Storm and Alexey Pertsev. Over the next two months, 100% of protocol fees from Keyring’s zkVerified vaults on the Ethereum mainnet will be allocated to their legal defense funds. Keyring’s zkVerified permissioned vaults enable compliant, privacy-preserving DeFi lending. Users can deposit USDC into these vaults to earn rewards, while the collected fees are directed to support the privacy-focused developers. So far, the vaults have generated $22,109.52 in fees.

The Ethereum Foundation released a roadmap for Kohaku, an open-source initiative designed to make crypto wallets both secure and private, while minimizing reliance on trusted third parties. The project is led by Vitalik Buterin and Nicolas Consigny, a protocol support member at the Ethereum Foundation. Kohaku aims to make privacy a normal and accessible feature for everyone, enabling users to transact privately and securely without sacrificing decentralization or usability. The roadmap includes a wallet SDK and a reference implementation that wallet teams can adopt to integrate private and secure transaction capabilities.

Robinhood has launched trading for tokenized stocks and ETFs for its European customers, enabling users to access to more than 200 U.S. equities onchain. The launch includes zero-commission trading, dividend payouts, and 24/5 market access. Currently, tokenized stocks are live on Arbitrum One, with plans to migrate them to Robinhood Chain, the company’s upcoming Layer 2 network built on the Arbitrum Orbit stack. For every share purchased, a corresponding token is minted onchain. In future updates, users will be able to transfer stock tokens to self-custodial wallets.

Concrete, a DeFi yield infrastructure provider, launched the Staked EIGEN Vault, a yield-optimizing product that turns EIGEN tokens into productive assets within the EigenLayer ecosystem. The vault combines EigenLayer’s native restaking yields with Concrete’s delta-neutral trading strategies, targeting 6–8% USD-denominated returns. By depositing EIGEN, users earn yield and ecosystem incentives while receiving sEIGEN, a liquid vault token representing their share of the underlying strategy. EIGEN serves as the native staking, governance, and incentive token of the EigenLayer restaking protocol.
