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 Launches Digital Identity On EthereumBhutan, 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 Prividium Breakthrough InitiativeZKsync 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 Holds 3 Million ETHBitMine 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.Other NewsPrivacy on Ethereum #14Sophon introduces a stablecoin card Octant opens creator programEthereum Community Hub goes liveVirtuals AI hackathon closes soonBinance compensates users $283mDisclaimer: Content is for informational purposes only, not endorsement or investment advice.
