Ethereum saw three closely watched developments land in the same stretch: Vitalik Buterin confirmed that an AI-assisted tool identified him as the author of an anonymous technical document, a proposal outlined how Bitcoin-style UTXOs could work on Ethereum, and Bitmine Immersion Technologies said it added 42,197 ETH in a single week, taking total holdings to 5,742,237 ETH.
Buterin confirms AI-assisted authorship discovery
Earlier this year, Buterin challenged the public to identify a document he had written under a pseudonym. On July 6, 2026, he said researcher Franklyn Wang solved it in less than two weeks using an AI-assisted analysis tool called Co-Invest.
The document was the December 2024 revision of EIP-7503, known as Zero-Knowledge Wormholes, submitted through the anonymous GitHub account 0xwormhole. Buterin also described the method behind the disguise: he wrote the original draft in Chinese, ran it through a local AI translation model, and then manually cleaned up the English. That process left stylistic traces Wang's tool was able to detect.
EIP-7503 focuses on private ETH movement
EIP-7503 proposes a model in which users burn ETH into an unspendable address and later re-mint it elsewhere with a zero-knowledge proof. The goal is to break the on-chain link between sender and receiver without relying on a separate mixing application.
The proposal is centered on transaction privacy, not on creating a new asset. Its authorship reveal arrived at the same moment that two other Ethereum stories were moving through the market, putting privacy research, state design, and treasury accumulation into the same conversation.
Native UTXO proposal targets Ethereum state growth
On the same day, a detailed design for bringing Bitcoin-style UTXOs to Ethereum was published. The idea keeps Ethereum's account model in place, but treats simple payments as one-time objects. Under the current structure, every new address that receives ETH or a token creates a permanent state entry.
The proposed design would instead prove a UTXO from history and keep only a single spent bit on-chain. According to the proposal, that could cut permanent state usage for payment-only transactions by about 99.8%.
It also depends on Frame Transactions, or EIP-8141, allowing a UTXO to pay its own gas and fund its own spend even if the receiving address holds zero ETH. That addresses a long-standing fee problem for fresh one-time-use addresses, including stealth payment use cases.
Bitmine lifts ETH holdings toward the 5% target
Corporate accumulation moved at the same time. Bitmine Immersion Technologies (NYSE: BMNR) said it bought 42,197 ETH in one week, bringing total holdings to 5,742,237 ETH. Using the article's reference price of $1,800 per ETH, that stack is worth about $10.3 billion, or roughly 4.8% of Ethereum's total supply.
Beyond ETH, Bitmine reported holdings of 206 BTC, minority stakes in Beast Industries and Eightco Holdings, and $527 million in cash and securities. Its combined crypto, cash, and “moonshot” holdings were listed at $11.1 billion.
The company also said 4,879,157 ETH is staked through its MAVAN validator network, generating an estimated annualized reward stream of $235 million or more. Chairman Tom Lee said Bitmine remains on course for its stated goal of owning 5% of all ETH before year-end.
Privacy research, state efficiency, and market structure moved together
Taken together, the three developments point to different layers of Ethereum's evolution: EIP-7503 on privacy, native UTXO design on state efficiency, and Bitmine on institutional ETH concentration. The next items to watch are whether EIP-7503 or the native UTXO design is scheduled for a future hard fork such as Hegotá, and whether client teams comment on EIP-8141, which both designs depend on.
