Puffer Upgrades UniFi Preconf AVS to Deliver Sub-10ms Execution With Restaked Security
Puffer Finance supports scalable protocol deployment by combining unified restaking, rollup‑based infrastructure, and modular composability. With this upgrade, its UniFi Preconf AVS delivers a production‑ready mechanism for Ethereum‑native transactions that are executed within sub‑10 ms guarantees at a fixed price, with slashing collateral and rollup revenue-sharing incentives supporting economic security.
By design, rollups inherit Ethereum's approximate 12‑second block times, which limits performance for latency‑sensitive applications. Puffer's upgraded Preconf AVS addresses this by offering execution guarantees that ensure exact transaction outcomes at the time of transaction, rather than relying on later settlement prices.
The enforcement mechanism leverages EigenLayer's restaked ETH model. Validators and gateway operators back their sequencing commitments with slashing risk to mitigate potential liveness failures, toxic MEV exposure, or protocol-safety faults. The deployment currently secures in excess of 3 million ETH in restaked assets, providing significant economic depth for all UniFi‑integrated rollups.
Key Features of the Upgrade
Delegated Gateway Rights: Validators delegate block proposer responsibilities to specialized gateways focused on sequencing.
Lookahead Scheduling: Gateways receive advance visibility into upcoming L1 slots for precise coordination.
Refund Mechanisms: Users are refunded if Preconf execution fails.
Three‑Phase Rollout:
Phase 1: Early gateway access with validator delegation, no slashing—missed events forfeit rewards. First implementation supports sub‑100 ms confirmations via the Gattaca frags‑based gateway.
Phase 2: Expanded gateway participation and implementation of lookahead scheduling. Incentive structures modular and more decentralized.
Phase 3: Introduction of slashing for liveness or MEV risks (ranging from ~1 ETH to 1,000 ETH), integration with Ethereum's Universal Registry Contract, post-slash challenge/fraud‑proof periods, and mechanisms to redistribute or reclaim slashed collateral.
Additionally, a rewards distribution system has been introduced. Rather than routing all gains from preconfirmations to L1 proposers, a dynamic revenue-sharing model allocates incentives among validators, gateway operators, and rollup operators. Slashed funds are either refunded to affected users or retained within the Preconf rewards pool, aligning rollup operator interests with Ethereum's decentralization goals without fragmenting liquidity.

Cathie Wood Is Buying Shares of This Little-Known Ethereum Treasury Company. Should You?
Cathie Wood is known for making bold bets on disruptive technologies. Her latest move is catching attention in the crypto world. Through Ark Invest's flagship funds, she has been buying up shares of BitMine Immersion Technologies (BMNR), an under-the-radar company building an Ethereum (ETHUSD) treasury. BitMine recently shifted its focus to Ethereum and has already built holdings worth more than $2 billion. The company's goal is to acquire 5% of all ETH in circulation. Ark Invest has been adding millions of BitMine shares across its exchange-traded funds including its flagship Ark Innovation ETF (ARKK), showing its confidence in BMNR.

Amazon's $36M Bet on Quantum Computing: What Investors Need to Know AMD Stock Slips After Q2 Earnings, But Here's Why It's a Buying Opportunity Tired of missing midday reversals? The FREE Barchart Brief newsletter keeps you in the know. Sign up now! For investors watching Cathie Wood's next big play, BitMine could be a unique opportunity in the growing Ethereum treasury market. About BitMine Stock Based in Las Vegas, BitMine Immersion Technologies is a tiny crypto firm that has suddenly grabbed headlines. The company started as a Bitcoin (BTCUSD) miner and focuses on the accumulation of crypto for long-term investment using mining and capital raises to build its holdings. In mid-2025, BitMine announced a major pivot: a $250 million private stock placement at $4.50 per share to finance an 'Ethereum treasury strategy.' Management says the proceeds will be used to buy Ethereum and make ETH the company's primary treasury reserve asset. Following the announcement, BitMine's stock went on a meteoric run. In early July, shares briefly spiked over 3,000%, touching $161 at the peak as investors embraced the company's bold Ethereum treasury pivot. Despite the rapid rise and sharp swings, the stock remains up roughly 385% year to date, underscoring the speculative buzz surrounding BitMine's dramatic strategy shift. Valuation wise, BMNR's looks expensive at the moment. The price-sales ratio is 40.5x, considerably higher than the sector median of 3x, indicating a very expensive stock compared to its peers. Cathie Wood Bets Big on Bitmine In a recent move, Cathie Wood's Ark Invest has been aggressively buying BitMine stock. Over several trading days in late July and early August, ARK funds accumulated hundreds of thousands of BMNR shares. CoinDesk reports that ARK's Innovation and Next Gen Internet ETFs (ARKW) bought about 477,498 shares on July 30 alone, following 529,366 the day before, and then about 540,712 more shares on July 31, roughly $15 million to $17 million each day. How Is BitMine Doing Financially? Bitmines' financial performance has been mixed lately. In its latest quarter, BitMine's revenue was roughly $2.05 million, mostly from mining and equipment sales, up 68% year-over-year. Gross margins are thin and expenses are high, driven by depreciation, compensation, and operational costs. The net loss per share was $0.31 per share. As of early August, BitMine's treasury held 833,000 ETH, valued above $2.9 billion. The company said this officially made it the largest Ethereum treasury in th world. What Do Analysts Think About BitMine Stock? BitMine recently received a 'Strong Buy' rating from the sole Wall Street analyst tracked by Barchart. The analyst has set a mean price target of $60, suggesting the stock could potentially gain 60% from its current level. The Bottom Line Although ARK's interest has drawn attention to this stock, and Wood's firm is known for both big winners and high-risk plays, it doesn't change the fundamentals. BitMine remains a very small company with limited revenue. Its balance sheet is dominated by crypto holdings, which fluctuate in value with Ethereum and Bitcoin prices, and it continues to report ongoing mining expenses. Overall, it's a risky bet for me, but those with a higher risk appetite might welcome a chance to bet on this one.

Ethereum treasury buying catches up to ETFs as exchange reserves dry up
Ethereum's liquid supply is vanishing. After a year of feasting alone, exchange-traded funds now face competition from new Ethereum treasury firms hungry for their slice of an ever-shrinking pie. Both groups combined have now acquired roughly 3.2% — worth almost $14 billion — of the cryptocurrency's circulating supply since June 1, according to Geoff Kendrick, global head of digital assets research at Standard Chartered, the UK bank. Invest in Gold American Hartford Gold: #1 Precious Metals Dealer in the Nation Thor Metals Group: Best Overall Gold IRA Priority Gold: Up to $15k in Free Silver + Zero Account Fees on Qualifying Purchase In a note to investors on Wednesday, he noted that treasuries have accelerated their accumulation in recent weeks. As the buying spree picks up, exchanges are being drained of their available supply. Major platforms now hold around 18.8 million Ether worth just under $70 billion, down from roughly 28 million in mid-2022, according to CryptoQuant data. It's the lowest level seen since around 2016, when Ethereum was trading for less than $20. Kendrick believes these treasury firms may now offer investors a more compelling way to gain exposure to Ethereum than spot ETFs. Their market value is increasingly in line with the actual Ether they hold — a measure known as the NAV multiple. SharpLink, one of the most prominent Ethereum treasuries, saw its NAV multiple fall from over 2.5 in July to just above one, indicating a more grounded valuation. That shift, Kendrick argues, makes these firms more investable. 'I see the ETH treasury companies as a better asset to buy than the US spot ETH ETFs,' he said, pointing to potential upside from staking rewards and flexible regulatory treatment. 2017 Bitcoin moment Some analysts believe this could be Ethereum's version of Bitcoin's 2017 breakout. Fundstrat's Tom Lee described Ethereum as 'Wall Street's preferred chain' in a recent CNBC interview. He predicted the Ether price could rise as high as $30,000 — an almost tenfold increase — if the current cycle plays out. And with Standard Chartered's forecast suggesting treasuries could eventually control 10% of ETH's supply, the scramble may still be in its early stages. Crypto market movers Bitcoin has gained 0.9% over the past 24 hours and is trading at $115,000. Ethereum is up 2.8% in the same period to $3,720.

Here's What It Would Take to Make $1 Million From Ethereum in 10 Years
Key Points Ethereum will almost certainly be around in 10 years. The odds are very good that it will be worth a lot more at that point than it is today. That doesn't mean its moonshot potential is going to unfold perfectly. These 10 stocks could mint the next wave of millionaires › Building a skyscraper starts with a blueprint that looks bold on paper, but it takes more than an architect's sketches for the plan to become a reality. The same applies to the ever-popular dream of turning a modest investment in a cryptocurrency like Ethereum (CRYPTO: ETH) into a seven-figure stake. Making $1 million with this coin will demand aggressive price appreciation, unwavering discipline, and a healthy tolerance for volatility, not to mention for its roadmap to play out as conceived and then subsequently be well received by the market. Ready to see exactly what it would take? Crunching the numbers Let's start by envisioning the finish line. Today, the coin trades at about $3,600. Assume Ethereum coins change hands at $30,000 in mid-2035, which would make for roughly an eightfold gain. That likely would require the network to capture a dominant share of the capital related to decentralized finance (DeFi), tokenized assets, and artificial intelligence (AI)-native blockchain applications. Furthermore, at that price, you would need about 33.4 tokens to crest the $1 million mark. Buying that much over 10 years at an average price of $5,000 would cost roughly $167,000, or about $1,391 per month. Most investors cannot afford to allocate that much to one fairly risky investment on a monthly basis, but it might still be possible by siphoning some of the regular flows of capital devoted to buying safer investments, as inadvisable as that may be. Importantly, those numbers shrink a bit if the purchased coins are staked consistently; some validators currently offer staking yields near 4%, and there are some Ethereum exchange-traded funds (ETFs) that now pass on staking rewards to shareholders. The math here has three pillars. First, the future price. A $60,000 end price cuts the amount of coins needed in half, and it slashes the monthly purchasing requirement to about $700, which is more manageable. Alternatively, a much lower price would make the entire endeavor financially impractical. Second is the average purchase price. A nasty bear market could drop your average cost far below today's level, or a melt-up could push it sharply higher. The third pillar is your own consistency. If you miss a few months of buying, the entire plan starts to wobble fast. None of those pillars are guaranteed to hold, so investors must treat this projection as a best guess, not a promise. The assumptions carry a lot of load here Now that we have a few rough figures pinned down, it's time to vet the assumptions that underlie the chain's prospects for growth. Ethereum's dominance of the decentralized finance sector looks fairly sturdy today, though not quite as unassailable as it did in 2021, and even less so compared to its strength in 2017. It hosts roughly $80 billion of the DeFi sector's $134 billion in total value locked (TVL), which is good for a market share of about 60%. If that share persists while the sector triples, the network's fee revenue, and by extension its staking rewards, would doubtlessly swell. Meanwhile, the broader smart contracts market is projected by Research and Markets to grow at a 23% compound annual growth rate (CAGR) through 2029 as more industries automate processes on-chain. It's practically a given that Ethereum will continue to capture a big share of that market, and AI agents that write, audit, and trigger smart contracts could juice growth even further. Evolving regulation rounds out the bullish case. A May 29 statement from the Securities and Exchange Commission (SEC) signaled a path for staking to remain legal when offered through registered intermediaries. Coupled with the first wave of ETFs, financial institutions finally have a compliance-friendly way to hold and compound Ethereum, which they are now starting to do. So, at least on the surface, Ethereum has a decent chance of being able to grow quickly enough to meet the requirements for investors to become millionaires during the next decade, provided they continuously invest some capital on a regular basis. This is not a slam dunk in any way Now for the cracks in the mirror. Rival smart contract chains like Solana offer lower fees and faster transaction speeds. They're also courting developers, both of which could chip away at Ethereum's market share and, in time, potentially supplant it entirely. And while U.S. regulators appear friendlier today, policy shifts can arrive overnight. Any one of these shocks could flatten staking yields, stunt price growth, or both, stretching the $1 million timeline well past 10 years. Therefore, aiming to amass $1 million in Ethereum within a decade is possible on paper, but it relies on a stack of optimistic assumptions that are not very sturdy. The base case here won't get most investors to the million-dollar mark with a reasonable amount of investing over time, even if it will likely make them significantly richer. Most investors will be better served by stretching the time horizon out, lowering the monthly contribution to a level that will not tempt them to bail during a crash, and letting the network's slower, steadier growth do the heavy lifting during the next 15 or 20 years instead. Don't miss this second chance at a potentially lucrative opportunity Ever feel like you missed the boat in buying the most successful stocks? Then you'll want to hear this. On rare occasions, our expert team of analysts issues a 'Double Down' stock recommendation for companies that they think are about to pop. If you're worried you've already missed your chance to invest, now is the best time to buy before it's too late.
