Redefining Privacy: Howard Wu on Aleo, Zero-Knowledge, and the Future of Blockchain Confidentiality

In this interview, Howard Wu, Founder of Aleo and CEO of Provable (an Aleo Labs company that focuses on developing products for compliant and confidential payments, as well as creating tools for developers to deploy and manage apps on the Aleo blockchain) shares how they are rethinking privacy in the blockchain era through the use of zero-knowledge proofs.
With transparency long considered a massive cornerstone in our industry, Wu argues that true innovation lies in programmable privacy – a concept that allows users and developers to decide what data is shared and with whom.
Join us in an interesting and thought-provoking conversation centered around the fundamental beliefs of the cryptocurrency industry.
Aleo is built around the concept of privacy-preserving applications using zero-knowledge proofs. In your view, how does Aleo fundamentally redefine what privacy means in the blockchain space?
Transparency is one of the founding principles of blockchain transactions, creating a new community based on public accountability. However, as blockchain evolves, the community has increasingly recognized that absolute transparency can be problematic. Businesses need confidential transactions, individuals don’t want to expose all of their financial data publicly, and applications that manage personal data need to be able to decide what information should be public and what should be private.
Aleo is the first ZK blockchain designed with programmable privacy as a core principle, rather than an afterthought, opening up entirely new use cases that allow people to protect their application state and personal data from misuse.
Aleo is known for its vertically integrated stack—from the Leo programming language to snarkOS and snarkVM. Why was vertical integration a strategic choice, and how does it shape the developer experience on Aleo?
As developers ourselves, we wanted to give Aleo devs the simplest developer experience possible. From Leo, our Rust-based DSL, to snarkOS and snarkVM, developers have everything they need to build in one place. By abstracting away the low-level cryptography, developers can focus on the logic of their application and not the extensive cryptography knowledge that used to be needed to build with zero-knowledge.
With the Aleo mainnet now live, what kinds of real-world use cases are you most excited about, and what signals are you seeing that point to ecosystem traction?
Every time we share personal information with each other or with an organization is an opportunity for zero-knowledge to make that process safer and more secure. With that being said, zero-knowledge has immense potential to change the way we send payments online. The transparency offered by the blockchain isn’t conducive to making payments – why would we want the details of our transactions, including amount, sender and receiver, public? And more importantly, our entire wallet history is available anytime we send and receive money too.
This is blocking enterprise adoption of cryptocurrency in different finance applications, including payroll and cross-border payments. On Aleo, transactions can be sent privately and compliantly, opening up these new use cases for businesses around the globe.
Open-source is a central theme in Web3. How does Aleo balance building sophisticated cryptographic tools while keeping the ecosystem open and accessible to developers?
All of our software to run and operate the Aleo Network is fully open-sourced. In addition, our programming language, Leo, is also fully open-sourced. We want Aleo to be a decentralized and permissionless ecosystem.
We have prioritized publishing our technical roadmap to be open and visible to all community members. This level of transparency ensures projects building on Aleo know exactly what the core developers are focused on at any given moment, and when these are expected to land on the network as well.
All of our core protocol upgrades are made through collective decisions with our community. We use ARCs (Aleo Request for Comment) as our governance process, and have ARCs posted on vote.aleo.org to allow for community members to vote on the proposal. Once a quorum and minimum amount of “approve” votes is achieved, this is then moved forward onto the release pipeline.
Zero-knowledge proofs are powerful but often resource-intensive. How has Aleo approached the challenges of scalability and efficiency without compromising on privacy?
We designed Aleo to use an incredibly efficient zero-knowledge proof system, all without compromising on user or data privacy. Namely, the type of zero-knowledge proofs we use verify in mere milliseconds and are under 1KB in size. This differs in design from many other zero-knowledge proof systems out there and we’ve been able to use these properties of our solution to scale the throughput of consensus on the Aleo Network by supporting batch executions of programs and parallel verifications of transactions on the network.
As new proof systems evolve, we’ve also designed Aleo to be upgradable, so that we can incorporate newer technologies into the blockchain and allow for the network to scale even further.
Looking ahead, how do you envision the regulatory landscape evolving for privacy-preserving blockchains, and what role do you see Aleo playing in shaping that future?
I believe we’ll reach a balanced state that recognizes the need for oversight but also the need for privacy. We’re already seeing privacy as a fundamental right gaining ground culturally, and it’s a matter of time before regulatory standards evolve to meet it.
By building compliance tools directly into our platform, we’re positioning Aleo to be ahead of the curve addressing any potential future regulations while maintaining With all state on Aleo private-by-default, payments made on Aleo utilize an account view key to decrypt and read transactions. Developers are able to control which parties see what transaction data, allowing for more granular compliance control.

Ethereum Foundation, Whales, and Hackers: What’s Driving the ETH Sell-Off?

TL;DR
- Whales, hackers, and the Ethereum Foundation wallets moved over $500M in ETH through large sales and withdrawals.
- Ethereum transfers rose to 4.6M ETH, nearing the monthly high of 5.2M recorded in July.
- Staking inflows hit 247,900 ETH, the highest in a month, locking more supply from trading.
Large Withdrawals and Whale Activity
Ethereum (ETH) has seen heavy movement from major wallets over the past few days. On-chain data from Lookonchain shows a newly created wallet pulled 17,591 ETH, worth $81.62 million, from Kraken in just two hours.
Over three days, two new wallets withdrew a combined 71,025 ETH, valued at $330 million, from the exchange.
One of these wallets, address 0x2A92, has withdrawn 53,434 ETH, worth $242.34 million, in two days. This includes a recent purchase of 30,069 ETH, valued at $138.46 million, during a market drop.
Major ETH Holders Offload Millions Amid Price Rally
In contrast, several separate entities have been disposing of some ETH holdings. A wallet tied to a hacker address 0x17E0 sold 4,958 ETH for $22.13 million at $4,463, securing a profit of $9.75 million. Earlier this year, the same address sold 12,282 ETH at $1,932 and later bought back part of the amount at higher prices.
A different whale sold 20,600 ETH for $96.55 million over the past two days, generating a profit of more than $26 million after holding the position for nine months.
Meanwhile, an Ethereum Foundation-linked wallet, 0xF39d, sold 6,194 ETH worth $28.36 million in the last three days at an average price of $4,578.
Recent sales from the same wallet included an additional 1,100 ETH and 1,695 ETH for over $12.7 million combined.
The #EthereumFoundation-linked wallet(0xF39d) sold another 1,300 $ETH($5.87M) at $4,518 ~11 hours ago.
Over the past 3 days, this wallet has sold a total of 6,194 $ETH($28.36M) at an average price of $4,578.https://t.co/4hfCWymHVG pic.twitter.com/ErUyEY8SJy

Network Activity on the Rise
CryptoQuant data shows Ethereum’s total tokens transferred have been climbing since August 9. After ranging between 1 million and 3 million ETH through late July and early August, transfers have risen to 4.6 million ETH, approaching the monthly high of 5.2 million recorded in mid-July. This increase has occurred alongside a price rally from about $3,400 to $4,600.
Interestingly, staking inflows generally stayed between 20,000 and 80,000 ETH per day over the past month. On August 14, inflows jumped to 247,900 ETH, the highest in the period.
At the time, ETH was trading near $4,600. Large staking deposits reduce the amount of ETH available for immediate trading, as staked coins are locked for a set period.
In the meantime, ETH trades at $4,647 with a 24-hour volume of $68.25 billion, down 2% on the day but up 19% over the week.

Massive DOGE Whale Activity Hints at $1 Breakout

TL;DR
- Whales bought two billion DOGE this week, lifting their combined holdings to 27.6 billion coins.
- A single 900M DOGE transfer worth $208M to Binance drew attention to large exchange movements.
- DOGE broke key resistance, with momentum building for a possible push toward the $1 price mark.
Price and Market Moves
Dogecoin (DOGE) traded at $0.23 at press time, slipping 4% over the past day but still showing a 2% gain for the week. Daily turnover came in at about $6.18 billion.
Meanwhile, the broader crypto market saw over $1 billion in liquidations. Hotter-than-expected US Producer Price Index data pushed traders to scale back expectations of a near-term Federal Reserve rate cut. DOGE had roughly 290,500 coins liquidated during the sell-off.
On the two-week chart, analyst Trader Tardigrade notes that DOGE has cleared a downward-sloping resistance line after completing what appears to be a “wave V” in an Elliott Wave sequence. Similar setups in the past, where prolonged declines stayed within falling channels before breaking higher, have been followed by sharp rallies.

Momentum gauges are also turning up. The Stochastic RSI, which had dropped into oversold territory, is now heading higher. Previous reversals from this zone have coincided with sustained upward moves. The current formation points to a possible run that could carry DOGE past the $1 mark.
Heavy Whale Buying and Large Transfers
As reported by CryptoPotato, blockchain data shows large investors have added two billion DOGE in the past week, spending just under $500 million. That brings their holdings to about 27.6 billion coins, or 18% of the supply. The buying streak has prompted speculation within the community.
Recently, Whale Alert flagged a 900 million DOGE transfer worth about $208 million into Binance. The tracking indicates that it originated from a wallet connected to the exchange, likely as an internal activity. The address involved holds 2.88 billion DOGE, one of the largest balances on the network.
Ali Martinez also reports that transactions above $1 million reached a one-month high, with activity building since early August and peaking as DOGE traded at $0.25.

Sentiment Building
Analyst Gordon described the current setup as “a nice bit of consolidation” before a potential breakout, adding,
“This will be one of the first coins normies FLOCK to & the pump will be MASSIVE.”
With whale accumulation rising, high-value transfers increasing, and a bullish technical pattern in play, DOGE is positioned for a potential push toward $1 if momentum holds.

Ripple Price Analysis: XRP at Risk as Key Support Levels Could Trigger Sharp Drop

XRP has recently entered a consolidation phase after a strong rally earlier this summer, with the price action now hovering around key resistance levels on both its USDT and BTC pairs. Yet, while momentum has slowed, the charts still indicate a generally bullish structure, with multiple key support levels remaining firmly in place.
Technical Analysis
By ShayanMarkets
The USDT Pair
On the XRP/USDT daily chart, the price is currently trading near the $3.10 mark, facing a strong resistance zone around $3.40. This follows a breakout above the $2.70 range in July, which has now flipped into a support area.
Both the 100-day and 200-day moving averages are also trending upward and recently formed a bullish crossover around $2.45, reinforcing the medium-term bullish sentiment. If the $3.40 resistance breaks, a push toward the critical $4.00 range becomes likely.
However, the RSI hovering near the neutral 50 level suggests a lack of strong momentum for now, meaning a short-term pullback into the $2.80 support zone is still possible.
This zone will be key for maintaining the bullish structure. Losing it could open the door for a deeper correction toward the 200-day moving average located around the $2.40 mark. Yet, as long as the price stays above the moving averages, the broader trend remains bullish.
The BTC Pair
Looking at the XRP/BTC chart, the pair has recently pulled back after hitting the 3,000 SAT resistance, with the price currently around 2,600 SAT.
This follows a clean breakout above the long-term descending channel and a successful retest of its upper boundary, which coincided with the 200-day moving average and the 2,400 SAT support zone. This confluence remains a key bullish technical factor, as holding above it could attract renewed buying pressure.
That said, RSI levels around 48 show that momentum has cooled after the sharp July rally, meaning XRP may continue ranging between 2,400 SAT and 3,000 SAT in the near term. A decisive close above 3,000 SAT would likely open the path to the 3,400 SAT zone, while losing 2,400 SAT could shift the bias back toward 2,000 SAT support. For now, the structure still favors the bulls as long as higher lows remain intact.
