Solana Foundation detailed a plan to address future quantum computing risks and protect network security. The foundation confirmed that core developers aligned on a post-quantum signature standard. It said the threat remains distant, yet teams have prepared migration strategies.

Solana Aligns Core Teams on Falcon Quantum-Resistant Signatures

The Solana Foundation said its core teams selected Falcon as a post-quantum digital signature scheme. Anza and Jump Crypto’s Firedancer reached the same conclusion through independent technical reviews. The foundation stated that both teams have started building early Falcon implementations for testing.

The foundation said Solana developers examined performance tradeoffs before selecting Falcon for integration. The network’s high-speed design requires low latency and efficient cryptography. However, developers concluded that Falcon can operate within existing technical limits without harming throughput.

The foundation said it will continue research and testing before any protocol change. It added that developers understand migration steps and maintain readiness for deployment. “Quantum is still years away,” the foundation said in its blog update.

Roadmap Covers Wallet Migration and Ecosystem Tools

Solana outlined a phased roadmap for introducing post-quantum protections across the network. The plan includes research on Falcon and other cryptographic options. It also covers potential deployment for new wallets if quantum risks increase.

The foundation said developers could introduce post-quantum schemes for newly created wallets first. Later, teams would migrate existing wallets through planned updates. The foundation stated that such a transition would remain manageable under the current infrastructure.

The blog post also referenced ecosystem work that already supports quantum resistance. Blueshift launched its Winternitz Vault primitive on Solana more than two years ago. The foundation said Google Quantum AI recently cited this implementation in research materials.

The foundation explained that Winternitz Vault operates as a quantum-resistant primitive on chain. It allows users to store assets with alternative cryptographic safeguards. Developers have maintained the tool live on Solana without protocol disruption.

Solana developers stated that they will monitor advances in quantum computing research. They will adjust timelines based on scientific progress and industry benchmarks. The foundation emphasized that no immediate network changes are scheduled.

The foundation said internal testing of Falcon implementations will continue across both core teams. Anza and Firedancer engineers will refine performance benchmarks during development cycles. The foundation confirmed that deployment would follow clear governance processes.

• Pudgy Penguins (PENGU) price touched $0.010 amid double-digit gains.
• The token surged as the Pudgy Penguins floor price pumped.
• Other non-fungible tokens also soared, including the Bored Ape Yacht Club.

Pudgy Penguins’ native PENGU token is up double digits in the past 24 hours, riding high on skyrocketing floor prices to touch three-month highs.

This surge comes amid notable price increases in the Pudgy Penguins NFT, with other tokens related to the sector also experiencing significant gains.

However, an uptick for Bitcoin and Ethereum fizzled on Monday, a scenario that puts the tokens’ prices in danger of retreating amid profit-taking.

Pudgy Penguins soars 14% amid NFT price gains

Data shows top non-fungible token collections are experiencing a remarkable resurgence, with floor prices extending their upside momentum.

Pudgy Penguins currently leads the charge as its floor price climbs above 5 ETH, with over 20% in weekly gains.

Market data highlights this momentum, with over 20 sales and nearly 1,000 ETH in trading volume over the past seven days.

The Bored Ape Yacht Club (BAYC) NFT boosts similar metrics and shows an 81% spike in floor price over the last 30 days.

Yet, this optimism contrasts with contracting overall NFT market participation.

Global sales, transactions, and active users have nearly halved since February, even as average sale prices have more than doubled.

This divergence suggests a concentration of capital among high-value collections like Pudgy Penguins, potentially signaling selective bullishness rather than broad recovery.

Notably, PENGU price is up 40% over the past week, and the 14% gain in the last 24 hours has pushed it to above $0.010 for the first time since late January.

Pudgy Penguins is in double digits up year-to-date.

​Pudgy Penguins price analysis

Analysts attribute the NFT rally primarily to surging cryptocurrency prices, with Bitcoin (BTC) recently touching $80,000 and Ethereum (ETH) reaching $2,400.

The broader market sentiment looks to have amplified demand for top-tier NFTs, where Pudgy Penguins has stood out with elevated transaction counts accompanying its price climb.

In the market, surging floor prices typically reflect strong conviction, and the opposite shows amid declining floor prices.

PENGU gains mirror Pudgy Penguins’ NFT momentum, and the upmove lifts bulls above the $0.008 supply zone.

The surge to above $0.010 makes the 100-day and 50-day moving averages key support levels at $0.0082 and $0.007.

Among technical indicators to note is the Relative Strength Index (RSI) that currently hovers above 70, signalling overbought conditions.

Traders may need to watch out for NFT market fatigue or a significant BTC pullback.

If this happens, PENGU price could test lower support levels, including Feb 6 low of $0.0052.

On the flipside, the moving averages hint at a potential golden cross, with price likely to extend towards the YTD peak around $0.014.

These additions brought the cumulative holder count to its current level. The team described the increase as a continuation of rising engagement across the ecosystem. The figures reflect on-chain wallet data recorded during the reporting period.

Shibarium Surpasses 1 Billion Transactions

Shibarium also reached a new usage milestone during the same period. The layer 2 network processed more than 1 billion transactions, according to the shared data. This achievement places Shibarium among networks with high cumulative activity counts.

The team confirmed the milestone while outlining recent network statistics. It stated, “Shibarium has now crossed 1 billion total transactions.” The update linked the transaction growth to expanding network usage.

Transaction volumes increased as wallet numbers climbed during the week. The network handled daily transfers that contributed to the cumulative total. Each processed transaction is added to the overall count tracked on-chain.

Shibarium operates as Shiba Inu’s layer 2 scaling solution. The network supports faster transactions and lower fees compared to the main Ethereum chain. Developers continue to build and deploy projects within the ecosystem.

The 1 billion transaction mark reflects total processed transfers since launch. The data covers all confirmed transactions recorded on the network ledger. The team released the figures alongside updated holder statistics on April 27, 2026.

The latest wallet additions and transaction totals represent the most recent verified data. Shibarium’s cumulative transaction count now stands above 1 billion as of April 27. Total SHIB wallet addresses exceed 1.585 million based on on-chain records.

BitMine Immersion Technologies, the Ether treasury company backed by Fundstrat’s Tom Lee, has expanded its ETH holdings for the second time in as many weeks, even as large unrealized losses underscore the strategy’s risks.

The company said Monday it purchased an additional 101,901 Ether last week, bringing its total holdings to roughly 5.08 million ETH. Its combined crypto and cash reserves now stand at about $13.3 billion.

The latest acquisition follows a purchase of 101,627 ETH a week earlier, which was the company’s largest accumulation since December.

Despite the aggressive buying, BitMine is sitting on more than $6.5 billion in unrealized losses, based on total investments of approximately $17.6 billion, highlighting the impact of recent volatility in Ether prices.

The share price of the NYSE-listed BMNR stock is down more than 20% year-to-date, according to Yahoo Finance data.

Still, the company is generating yield on a portion of its holdings. BitMine has staked roughly 3.7 million ETH, allowing it to earn rewards for helping secure the Ethereum network and validate transactions, a strategy that provides a steady income stream even during price downturns.

Ether, crypto markets show signs of stabilization

BitMine’s large purchases come as the broader crypto market shows early signs of stabilizing after months of declines through March.

Ether rebounded above $2,400 last week after falling to a low near $1,800 earlier this year, according to TradingView data. Despite the recovery, the second-biggest crypto by market cap remains down roughly 23% year-to-date.

The rebound mirrors a broader uptick across equities and other risk assets in recent weeks, suggesting improving investor sentiment.

However, the volatility underscores the challenges facing crypto treasury players. Companies that accumulate large digital asset reserves are highly exposed to price swings, which can lead to significant unrealized losses during downturns, even as they continue buying. 

While strategies like staking can generate yield, they often do little to offset large drawdowns in asset value, leaving balance sheets sensitive to market cycles.

• Strategy purchased 3,273 Bitcoin for $255 million at an average price of $77,906 per coin.
• The latest acquisition increased Strategy’s total holdings to 818,334 BTC.
• The company funded the purchase by selling 1,451,601 MSTR shares through its at-the-market program.
• Strategy’s Bitcoin holdings are now valued at about $63.7 billion at current market prices.
• The company’s position has returned to profit with an estimated gain of $1.9 billion.

Strategy expanded its Bitcoin holdings with a new 3,273 BTC purchase worth $255 million. The acquisition lifted total reserves to 818,334 BTC and returned the company to profit. However, Peter Schiff challenged Michael Saylor’s $1 million Bitcoin forecast and questioned the accumulation strategy.

Strategy Expands Bitcoin Holdings With $255M Purchase

Strategy confirmed it purchased 3,273 Bitcoin for about $255.0 million at an average price of $77,906. The company increased its total holdings to 818,334 BTC as of April 26, 2026. It acquired the entire stash for $61.81 billion at an average price of $75,537 per coin.

At current prices near $77,850, the holdings carry a market value of $63.7 billion. This valuation places Strategy at roughly $1.9 billion in profit. Earlier this year, Bitcoin traded below $70,000 and left the company’s position underwater.

Michael Saylor announced the purchase on X and reported a 9.6% Bitcoin Yield year-to-date in 2026. He also released the company’s Form 8-K filing with the U.S. SEC. The filing detailed that Strategy funded the purchase through its at-the-market equity program.

Between April 20 and April 26, 2026, Strategy sold 1,451,601 MSTR shares. The share sales generated $255.0 million in net proceeds after commissions. During the same period, the company sold no preferred stock.

Schiff Challenges $1 Million Bitcoin Prediction

Peter Schiff responded to Saylor’s update and targeted his $1 million Bitcoin forecast. In 2025, Saylor said Bitcoin could reach $1 million if Strategy acquired 5% of the total supply. Schiff argued that current accumulation trends do not support that outlook.

Schiff stated that Strategy now controls about 3.9% of the total Bitcoin supply. He said the company purchased 231,666 BTC since Saylor made the forecast. According to Schiff, similar price reactions to future purchases could push Bitcoin below $60,000 before Strategy reaches 5%.

He wrote that “if the next 231,666 BTC move the market as the last ones did, the price could be under $60,000.” Schiff used this calculation to dispute the $1 million target. He has repeatedly supported gold as an alternative store of value.

Schiff also criticized claims about covering a reported 11.5% yield on STRC with modest Bitcoin growth. He argued that continuous issuance raises the required price increase. He said falling STRC prices could force higher yields and strain the structure.

According to Schiff, selling Bitcoin to cover yields would pressure the market. He warned that such actions could trigger a “death spiral” unless Strategy cancels the dividend. Strategy’s latest Form 8-K filing, dated April 27, 2026, confirms the recent equity-funded purchase.

TLDR

• Bitcoin reached $79,488 before easing to $78,223 as futures activity powered the latest price move.
• CryptoQuant CEO Ki Young Ju said the current Bitcoin rally is driven by derivatives, not strong spot demand.
• On-chain data shows Bitcoin’s 30-day apparent demand metric remains in negative territory.
• Michael Saylor’s firm, Strategy, purchased $255 million in Bitcoin after a $2.54 billion acquisition last week.
• Bitcoin ETFs acquired more than $2.6 billion worth of BTC this month despite weak on-chain demand.

Bitcoin climbed toward two-month highs as derivatives activity powered the latest advance. The asset reached $79,488 before easing to $78,223 during the session. However, CryptoQuant CEO Ki Young Ju said futures markets, not spot demand, drive the current Bitcoin rally.

Bitcoin Rally Fueled by Futures While Spot Demand Stays Weak

Ki Young Ju stated that derivatives traders lead the present move in Bitcoin. He said rising open interest shows traders are increasing leverage across futures markets.

He explained, “This rally is futures-driven,” and he pointed to negative on-chain demand data. CryptoQuant data shows Bitcoin’s 30-day apparent demand metric remains below zero.

Meanwhile, institutional buyers continued acquisitions through direct purchases and exchange-traded funds. Michael Saylor’s firm, Strategy, bought $255 million in Bitcoin after acquiring $2.54 billion last week.

At the same time, Bitcoin ETFs accumulated more than $2.6 billion worth of BTC this month. Yet on-chain metrics did not reflect matching growth in spot-driven demand.

CryptoQuant data showed futures demand in strong positive territory during the same period. However, Ju said bear cycles end only when both spot and futures demand recover together.

He added that current data does not show that alignment. Therefore, the structure behind the Bitcoin rally remains uneven.

Short Squeeze Accelerates Bitcoin Price Surge

On April 23, Bitcoin rose from $76,351 to $79,447 within hours. The move marked a 4.05% increase during that session.

Carmelo Alemán, an on-chain analyst at CryptoQuant, attributed the surge to forced liquidations. He said short traders closed positions rapidly as prices climbed.

Open interest jumped from $24.88 billion to nearly $28 billion during the rally. This rise showed a sharp increase in leveraged futures positions.

Short liquidations exceeded $607.9 million in Bitcoin during that move. Ethereum short liquidations reached $580.9 million in the same period.

Together, short liquidations totaled about $1.19 billion across both assets. In contrast, long liquidations remained just above $111 million combined.

Alemán said the imbalance highlighted strong pressure on bearish traders. As shorts closed, forced buying pushed prices higher.

CryptoQuant data indicated that derivatives activity expanded faster than spot transactions. Therefore, leverage played a central role in the advance.

Ju reiterated that on-chain demand still shows weakness despite price gains. He stated that negative apparent demand contrasts with rising futures exposure.

Bitcoin traded near $78,223 after touching $79,488 earlier in the day. Open interest remained elevated near $28 billion at the latest reading.

Bernstein’s latest research paints IREN as potentially the next Bitcoin miner to pivot into AI infrastructure, anchored by a multi-billion-dollar deal with Microsoft. The note frames this move as part of a broader, upcoming shift in mining economics as operators redirect energy and capital toward high-margin AI compute rather than traditional crypto mining.

The analysts spotlight IREN’s AI cloud push, noting about 150,000 GPUs already contracted and forecasting an annual revenue run rate of roughly $3.7 billion once the capacity is fully functional. A five-year engagement with Microsoft sits at the core of the plan, with Microsoft committing GPU capacity for AI workloads and providing substantial prepayments that help fund the infrastructure expansion.

Overall, Bernstein estimates IREN’s GPU program amounts to about $5.8 billion in invested capital. The note emphasizes that this sum is largely funded through Microsoft prepayments and GPU-backed financing facilities, supplemented by other cash and capital sources, which helps keep borrowing costs comparatively favorable during the rollout.

Bernstein’s central thesis is that this transition could redefine IREN’s business model. The firm suggests IREN will progressively sunset its Bitcoin mining operations as it retrofits sites to accelerate cloud deployment. Rather than a wholesale shutdown, IREN is repurposing existing mining hardware and facilities—particularly in Texas and British Columbia—replacing ASIC rigs with GPUs designed for AI workloads.

On balance, Bernstein anticipates that IREN’s AI cloud revenue could emerge as the primary source of income in the coming years, with Bitcoin mining shifting into a legacy role as power capacity is redirected toward contracted, higher-margin AI computing workloads. The shift is already underway in practice, with the company pursuing a hardware and location strategy built around AI workloads rather than pure BTC production.

IREN isn’t isolated in this pivot. Several peers in the mining sector, including TeraWulf and HIVE Digital, have begun reallocating power and capital toward AI and high-performance computing, often while maintaining some level of ongoing BTC mining. The trend has sparked discussion about how AI data centers might reshape the economics of crypto mining, and whether the shift could stabilize revenue streams in a landscape of volatile energy prices and crypto cycles.

Key takeaways

• Bernstein identifies IREN as a potential leader in AI infrastructure, anchored by a Microsoft-backed, GPU-heavy expansion.
• Approximately 150,000 GPUs are contracted, with an estimated $3.7 billion in annual revenue run rate once the capacity is fully operational.
• Microsoft’s five-year agreement includes substantial prepayments that fund the build-out, complemented by GPU-backed financing.
• The broader GPU investment—around $5.8 billion—faces capital structure designed to minimize new debt through prepayments and financing facilities.
• Bernstein projects AI cloud revenue as the main income driver for IREN in the medium term, with Bitcoin mining becoming a legacy segment as energy capacity shifts to AI workloads.
• From an investor perspective, Bernstein assigns a $100 price target and maintains an Outperform rating, acknowledging dilution risks and the gradual wind-down of mining as factors.
• The sequence mirrors a wider industry transition, as other miners explore AI data-center strategies in parallel with existing mining operations.

Strategic pivot and financing mechanics

At the heart of the thesis is a deliberate redeployment of IREN’s physical footprint. Rather than shuttering operations, the company is retrofitting sites to host GPU farms that can support AI-centric workloads. The initial focus areas include North American locations such as Texas and British Columbia, where available power capacity and supportive infrastructure could accommodate high-demand AI compute tasks in parallel with ongoing mining activities.

The financial scaffolding reinforces the strategy. Microsoft prepayments and GPU-backed financing facilities are designed to underpin the capex-heavy transition, reducing the immediate need for traditional equity raises or debt funding. Bernstein notes that this arrangement can cushion the transition against capital-cost fluctuations, provided AI demand holds up through the deployment cycle.

Industry context: a broader AI data-center shift

The IREN narrative sits within a broader wave of miners examining AI and HPC as revenue diversification. Firms like TeraWulf and HIVE Digital have publicly signaled similar pivots, emphasizing the opportunity to monetize surplus power by supporting AI workloads in addition to BTC mining. If this trajectory persists, it could alter the economics of crypto mining by introducing longer-term, contracted revenue streams that are less sensitive to spot energy price movements.

Nevertheless, the transition introduces new risks. AI compute contracts typically involve longer commitments and higher upfront capex, which could heighten exposure to technology cycles and utilization risk. Execution quality, regulatory considerations, and the pace of AI adoption will shape whether these reorganizations translate into durable profitability for the companies pursuing them.

Investor outlook: what Bernstein sees for IREN

In its note, Bernstein assigns IREN a price target of $100, implying substantial upside should the company successfully scale its AI cloud platform while winding down mining. The target sits with an Outperform rating, reflecting confidence in the strategic shift but tempered by the dilution concern and the gradual decline of mining revenue. The target marks a revision from a prior $125 price objective, signaling a more cautious stance on near-term dilution and transition risk.

As of the report, IREN trades below the $50 level, presenting what Bernstein characterizes as roughly 10x upside potential if the AI infrastructure strategy materializes as envisioned. The firm emphasizes that the outcome depends on execution, the durability of Microsoft’s utilization, and the sector’s ability to absorb additional AI capacity in a market that remains sensitive to macro and energy-cost dynamics.

Beyond IREN, the trend toward AI data-center deployment across the mining sector is drawing attention from investors and regulators alike. The coming quarters will reveal how quickly these firms can scale GPU-centric operations, how favorable the financing terms remain, and whether AI demand proves resilient through varying market cycles.

As the industry watches, the central questions revolve around utilization risk, the pace of retrofits, and the long-term profitability of AI-first business models for crypto miners. If IREN and its peers can demonstrate stable AI revenue streams alongside disciplined capital management, the shift could redefine what it means to operate a crypto mining enterprise in the current era.

Investors should monitor quarterly updates for site retrofit progress, GPU procurement milestones, and disclosures on Microsoft utilization patterns. The trajectory of the AI cloud run rate and the evolution of the company’s funding framework will be telling signals for how quickly this strategic pivot can translate into sustained financial performance.

As the transition unfolds, the market will be keen to see whether the combination of Microsoft’s support and GPU-backed financing can sustain a robust AI compute business, and how durable these AI-driven margins prove to be in a competitive data-center landscape.

Tether has released an open-source development framework for Bitcoin mining, aimed at giving operators and developers unified control over hardware and software across mining operations.

According to Monday’s announcement, the framework combines a backend SDK and user interface tools to replace fragmented, vendor-specific systems, allowing miners to monitor devices, manage operations and build custom applications across sites from a single control layer.

It uses a modular architecture in which hardware exposes standardized functions and independent modules can be added without altering the core system, enabling integration across different machines, services and locations.

The toolkit supports deployment across Windows, macOS and Linux, and is designed to scale from individual setups to large industrial operations, with features for automation, monitoring and coordinated hardware management, Tether said.

The framework is designed to reduce reliance on proprietary tools and simplify operations across fragmented mining setups, where vendor lock-in and interoperability challenges can increase costs and limit flexibility.

Tether said the release builds on the company’s earlier open-sourcing of its Mining OS, extending its mining software stack with a development layer for building dashboards, workflows and analytics tools on top of existing infrastructure.

The move comes about a week after the company disclosed an 8.2% stake in Antalpha, a Bitcoin-focused lender and equipment financing provider with close ties to mining hardware supplier Bitmain.

Tether is the issuers of USDT (USDT), the largest stablecoin by market capitalization, accounting for about $190 billion of the roughly $320.7 billion global stablecoin market cap, according to DefiLlama data.

Miners continue to push into AI infrastructure

As Tether moves deeper into Bitcoin mining infrastructure, traditionally pure-play mining operators across the industry are increasingly turning to artificial intelligence and high-performance computing workloads to diversify revenue.

One of the earliest companies to pivot was CoreWeave, originally a crypto mining operation that began shifting toward cloud and high-performance computing in 2019 as demand for AI compute increased.

Since then, a growing number of publicly traded miners, including Riot Platforms, HIVE Digital, MARA Holdings, TeraWulf and Cipher Mining, have pursued similar strategies, redirecting power capacity and infrastructure toward AI and high-performance computing.

Last week, Core Scientific said it plans to raise $3.3 billion through senior secured notes due in 2031 to fund data center expansion and refinance short-term debt. 

On Monday, Hut 8 said in a filing that it is seeking to raise $3.25 billion in senior secured notes to fund a 245-megawatt AI data center in Louisiana, tied to a 15-year, $7 billion lease agreement with Fluidstack, according to The Miner Mag.

Some miners are moving further. Also on Monday, analysts from Bernstein said IREN, the largest publicly traded Bitcoin miner by market capitalization, will likely phase out its mining operations over time as it scales its AI cloud business.
