Privacy Is Key to the Next Phase of Ethereum

Ethereum introduced smart contracts to the world and spurred a Cambrian Explosion of innovation, including DeFi, NFTs, DAOs, and a universe of dApps. On July 30, the network will hit its 10 year anniversary.
The past decade of the ecosystem focused on proving Ethereum’s functionality and capabilities as well as enhancing efficiency through upgrades like The Merge, which marked the transition from Proof-of-Work to Proof-of-Stake. The next era requires a pivot to match the more mature ecosystem that it now supports — one that includes not just Web3 natives but financial institutions, governments, corporations, and people who don’t know what «yield farming» is but who may want to get a loan for their house with crypto collateral.
Amid increasing government and institutional involvement, the hope that crypto will contribute to creating a «free and open society,» an ideal originally expressed in A Cypherpunk’s Manifesto, is sometimes lost. For Ethereum to make good on that original promise, privacy must be a core tenant of its future.
Privacy is identity
Some degree of privacy is essential for financial safety and freedom. You wouldn’t want to reveal your net worth to the cashier every time you buy a latte or a slice of pizza, but this is essentially how crypto has been operating for the past decade — with the radical transparency of immutable ledgers recording every transaction publicly.
Not only does this level of transparency put individuals at risk for phishing and other attacks, but it also hinders the involvement of institutions that do not want to give their competitors an edge by revealing their activity. Though it is possible to retain pseudonymity through never interacting with a centralized platform, this is not practical for interactions that touch the real world.
People and businesses need to be able to interact with governments and banks through ID-linked accounts, and the key to enabling these types of interactions — without putting personal information in jeopardy to theft and misuse — is programmable privacy.
The solution is ZKP-powered technology
The solution is already here: Zero Knowledge Proof (ZKP)-powered smart contracts give users control over what information to share and with whom. With the programmable privacy enabled by ZKPs integrated into Ethereum at a foundational level, a world of applications are not just feasible but practical.
Products and services must comply with the regulatory requirements of each jurisdiction in which they operate. This includes collecting customer information in accordance with KYC guidelines, Countering-the-Financing-of-Terrorism (CFT) and AML laws. Typical KYC processes involve sharing some form of ID, such as a passport or driver’s license, along with personally identifying information (PII) like name, date of birth and address.
If captured by bad actors, this type of information can be used to target people in phishing scams and other types of attacks (see recent Coinbase data breach). Rather than requiring people to reveal their PII and make themselves and their data vulnerable to attack and theft, ZKP-powered solutions allow people to prove they are not operating out of sanctioned countries and to prove eligibility to participate, all without giving the platform their data and contributing to potential honey pots.
The possibilities enabled by ZKPs go well beyond compliance too. Airdrops currently suffer from Sybil attacks where AI bots beat out real human participants to give certain participants an outsized advantage. The same issue applies to decentralized governance. Decision making in a DAO cannot be truly fair and free unless it can be proven that the right number of votes are going to the right number of people — not bots. ZKPs offer a solution with «proof of humanity» via data provenance tools like zkPassport, zkEmail, and zkTLS.
Digital payments must provide the same privacy as cash. Payments in dollars, euros, and other sovereign currencies via stablecoins are another important factor in enabling mass adoption of DeFi applications, but this will never take off en masse without privacy guarantees. The same applies to decentralized mortgages, loans, and essentially any type of legal contract, which all require IDs to execute.
There are many other applications made possible with privacy as a core tenant of the Ethereum ecosystem. These include proving the authenticity of product or restaurant reviews, enabling secure digital voting, decentralized escrow services, carbon offsetting tracking, proving builder status on GitHub anonymously, and employment skill verification — all done in a secure, privacy-preserving way that doesn’t involve the sharing of sensitive PII to centralized providers.
Creating a culture that demands privacy
Though the technology exists to implement ZKP solutions today, challenges will need to be overcome before privacy is comprehensively reflected as a core value throughout the Ethereum ecosystem. Technical challenges with implementing ZKP-powered tech include the greater expense of ZKP transactions. Building ZKP-focused applications is also more complicated, posing a learning curve for builders. These are all solvable issues.
Other challenges are cultural: creating universal buy-in from the spectrum of participants in the value of privacy and coordinating the implementation of solutions across the tech stack, from protocol to wallet. There is also the misguided perception hurdle of privacy’s associations with illicit activity.
Changing technology is ultimately easier than changing minds, but the core ethos of crypto is, after all, a philosophical one — a technology that underpins a belief in freedom and the privacy of individuals and entities. If in another 10 years, we look back on another decade of Ethereum and can celebrate its role in enabling greater financial freedom, an emphasis on privacy will be key.

Asia Morning Briefing: The First AI vs BTC Environmental Impact Numbers are Here. And it Might Start a New Debate

Good Morning, Asia. Here’s what’s making news in the markets:
Welcome to Asia Morning Briefing, a daily summary of top stories during U.S. hours and an overview of market moves and analysis. For a detailed overview of U.S. markets, see CoinDesk’s Crypto Daybook Americas.
Mistral AI recently offered a rare benchmark in the Artificial Intelligence industry’s environmental disclosure, detailing the footprint of its flagship large language model, Mistral Large 2.
Over 18 months, training and operating this model generated 20.4 kilotonnes of CO₂-equivalent emissions, consumed 281,000 cubic meters of water, and depleted 660 kilograms of antimony-equivalent materials, Mistral’s report said. Notably, a single 400-token response from its chatbot, Le Chat, uses just 1.14 grams of CO₂, 45 mL of water, and 0.16 milligrams of mineral resources.
But how does this compare to bitcoin’s carbon footprint? After all, bitcoin’s energy use has been the subject of significant debate and is often cited when establishing bans on bitcoin mining in jurisdictions.
That makes AI inference seem downright frugal compared to Bitcoin’s proof-of-work engine. On average, one Bitcoin transaction emits between 600 and 700 kilograms of CO₂, consumes more than 17,000 liters of water, and generates over 130 grams of electronic waste.
Zooming out, the entire Bitcoin network emitted roughly 48 million tonnes of CO₂ in 2023, according to the Cambridge Centre for Alternative Finance. It also consumed over 2 billion liters of water and produced more than 20,000 tonnes of e-waste.
However, the Cambridge Centre’s numbers, although peer-reviewed, have been the source of considerable criticism and require important caveats.
First, Bitcoin’s electricity mix is not monolithic.
According to a survey of miners conducted by BTC Investment fund Batcoinz as of March 2023, Hydropower (23.1%), wind (13.9%), and solar (5%) collectively account for more than 40% of Bitcoin’s energy consumption. The difference between the numbers is because surveys done by Batcoinz include off-grid generation.
Nuclear energy, often considered carbon-neutral, accounts for another 7.9%. Gas and coal together represent 44%, but Bitcoin’s energy profile is more diversified than critics often assume.
Second, LLMs may benefit from a cleaner grid by default. For example, nuclear energy comprises over 22% of the European Union’s electricity generation, which reduces the CO₂ emissions associated with model training and inference in EU-based data centers such as Mistral’s.
That advantage isn’t due to model architecture, it’s grid geography. A U.S.-based training run drawing from coal-heavy regions would present a very different environmental profile.
So while the marginal footprint of using an LLM is vastly smaller than processing a BTC transaction, both operate within infrastructure landscapes that significantly shape their true environmental impact.
Training frontier models like GPT-4 or Gemini can still require millions of GPU-hours and heavy water consumption, depending on location. Still, Bitcoin’s design, mining every 10 minutes regardless of demand, results in a fixed energy cost that scales with time, not usage.
In contrast, AI’s marginal cost scales with the frequency of model usage. That distinction makes the emissions from a chatbot reply easier to amortize than those from a block reward.
As global scrutiny increases over the environmental costs of computation, transparency initiatives like Mistral’s, provide important reference points.
While proof-of-work is energy-intensive, the Bitcoin blockchain’s halving mechanism steadily reduces the rate at which new coins are created, encouraging miners to become more efficient over time. Its environmental footprint should be weighed against the utility it provides in securing a decentralized, global financial network.
Continued improvements in clean energy adoption and mining optimization will be key for both BTC and AI as they scale into core pillars of the digital economy.
Market Movers:
BTC: Bitcoin is trading at $119,500, struggling to maintain momentum after last week’s all-time high of $123,100, as retail-driven sell pressure on Binance has pushed Net Taker Volume below $60 million and signaled growing bearish sentiment, according to CryptoQuant.
ETH: Ether has pulled back over 3% to $3,696 after a multi-week climb toward $4,000, as technical indicators flash red and analysts question whether the rally can continue without a broader correction, despite ongoing institutional accumulation.
Gold: Gold prices rose nearly 1% on Tuesday, with spot gold reaching a five-week high of $3,430.41 amid ongoing trade uncertainty and falling US bond yields, which continue to draw investor interest.
Nikkei 225: Asia-Pacific markets opened higher after U.S. President Donald Trump announced a “massive Deal” with Japan, lifting tariffs to 15% on Japanese exports, with the Nikkei 225 rising 1.71% at the open.
S&P 500: US stocks closed mixed Tuesday, but the S&P 500 edged slightly higher to a record 6,309.62 as investors weighed earnings reports

Dan Tapiero Projects Crypto Economy Hitting $50T, Launches $500M Fund Under New Firm

Well-known digital asset investor Dan Tapiero is merging private equity firms 10T Holdings and 1RoundTable Partners under a new brand 50T, reflecting his forecast that the digital asset ecosystem will reach a market value of $50 trillion in the next decade.
«50T is a natural evolution from our original thesis in 2020 when we launched 10T with the belief that the digital asset ecosystem would grow from $300 billion to $10 trillion in 10 years,» Tapiero said in a Tuesday press release.
«Today, we estimate that we’re already at $5 trillion, far exceeding our initial timeline, which is why we’re adjusting our outlook upward,» he said. «Recent successes like the Circle IPO and Deribit acquisition demonstrate the maturity of this sector and validate our investment thesis that all value will eventually move on-chain.»
USDC stablecoin issuer Circle surged nearly 10-fold from its initial price following its the stock market debut last month, while crypto exchange Coinbase acquired Deribit for $2.9 billion in May.
Funds under 50T were investors in Circle, Deribit, and digital trading platform Etoro, which also went public recently, and other portfolio companies are also gearing towards going public, the press release said.
50T is also launching a $500 million growth equity fund dubbed 50T Fund alongside the rebrand.
It’s a closed-end fund with a ten-year horizon, designed to back later-stage companies building out core infrastructure in blockchain and web3, with a first close planned in Q4 2025.

SEC Approves, Immediately Pauses Bitwise’s Bid to Convert BITW Crypto Index Fund to ETF

The Securities and Exchange Commission approved — then abruptly paused — Bitwise’s plan to convert its Bitwise 10 Crypto Index Fund (BITW) into a spot exchange-traded fund (ETF) on Tuesday, raising fresh uncertainty around the agency’s standards for crypto ETFs.
The fund holds 90% of its weight in bitcoin (BTC) and ether (ETH), with the remainder spread across Solana (SOL), XRP, Cardano (ADA), Avalanche (AVAX), Chainlink (LINK), Bitcoin Cash (BCH), Uniswap (UNI) and Polkadot (DOT). It manages $1.68 billion in assets and rebalances monthly.
Bitwise launched the fund in 2017. The 2.5% expense ratio remains steep by ETF standards, but the conversion to a spot ETF would make BITW the first multi-asset crypto index ETF in the U.S. — if it proceeds. The asset manager has not yet disclosed if the management fee would stay at 2.5%.
A similar product, Grayscale’s Digital Large Cap Fund (GDLC), which tracks BTC, ETH, XRP, SOL and ADA, also received initial SEC approval before the agency reversed course, pausing the fund’s launch.
A letter from the SEC on Tuesday said «the Commission will review the delegated action,» identical wording to the letter Grayscale received when its ETF was paused.
According to sources who spoke to CoinDesk at the time, the SEC’s hesitation likely stems from the need to establish consistent standards for crypto ETFs, particularly for tokens like XRP and ADA that do not yet have standalone ETFs.
The SEC’s ETF docket has been busy. On Tuesday, the regulator published filings from Franklin Templeton, Fidelity, Invesco Galaxy, and others seeking to amend redemption mechanics for their Bitcoin and/or Ethereum ETFs. It also launched a review of the Canary Capital SUI ETF and extended the deadline on 21Shares’ SUI ETF application.
Separately, 21Shares filed a proposal for an ETF tracking ONDO, the token powering real-world asset platform Ondo Finance.
