❤️ Microsoft debuts Surface RTX Spark Dev Box — Nvidia-powered mini-PC helps devs get ready for an agentic Windows

With the company pushing Windows as a platform for agentic AI with Nvidia's new processor, the Surface-branded mini PC is set to run sustained workloads with a 100W thermal envelope — more than you can get in a laptop.

Microsoft says that includes "long-running training jobs, agentic AI pipelines and local model fine-tuning."

Nvidia states that the RTX Spark can deliver up to one petaflop of AI compute with 128GB of unified memory and can run models with up to 120 billion parameters locally.

The system will come set up for developers, with Visual Studio Code, GitHub Copilot, and other applications preinstalled. Windows Subsystem for Linux 2 (WSL 2) with support for Nvidia's CUDA technology will also come out of the box, along with PowerShell7.

🤑 Stellar CEO says Clarity Act would help, but tokenization isn't dependent on it

⚪️Stellar Development Foundation CEO Denelle Dixon said said the GENIUS Act gave financial institutions confidence that the U.S. government intends to support the industry through a clearer regulatory framework.
⚪️She noted that firms such as Franklin Templeton were already building tokenized products before recent legislation, citing the firm's money market fund on Stellar.
⚪️While she said passage of the Clarity Act would benefit the industry, Dixon argued that tokenization adoption is unlikely to be derailed if the bill stalls.

🤪 Stellar is positioning its technology stack around compliance, privacy and scalability for large financial institutions.

➡️Dixon said Stellar has maintained 99.99.99% uptime and processes billions of transactions each quarter.
➡️She emphasized that compliance tools were built into the network’s architecture, reducing the need for custom smart contracts to issue assets.
➡️Stellar is also developing privacy features using a composable model that allows institutions to tailor controls to specific assets and use cases.

🔄 Massive transaction volumes remain a key test for blockchain-based financial infrastructure.

🟠DTCC processed $4.7 quadrillion in securities transactions last year, highlighting the scale traditional market infrastructure already supports.
🟠Dixon acknowledged that tokenized settlement volumes will ramp up gradually rather than reaching peak scale immediately.
🟠She said maintaining reliability and avoiding network outages are critical requirements for institutional adoption.❗️

🤝 Dixon expects tokenized assets to be distributed across multiple public blockchains rather than concentrated on a single network.

⚫️She rejected the idea that one blockchain will dominate all institutional tokenization activity.
⚫️Instead, Dixon said a handful of networks will likely capture most real-world asset issuance based on their technical strengths.
⚫️She argued that open public blockchains will ultimately outperform closed alternatives because they evolve rapidly through global developer participation.

🤑 Mastercard expands settlement capabilities to include stablecoin, intraday, holiday and weekend options

Mastercard today announced plans to expand its settlement capabilities with additional intraday, weekend and holiday card settlement, supporting both fiat currencies and on-chain card settlement using regulated stablecoins.

🔄 Together, these enhancements will give issuers and acquirers greater flexibility in how they settle card-based transactions across Mastercard’s global payments network, helping improve liquidity management and expanding choice in how money moves.

❗️Mastercard will support settlement using regulated stablecoins including Circle’s USDC, which is already supporting early on-chain settlement flows in select markets, as well as Paxos-issued stablecoins including PYUSD, USDG and USDP, Ripple’s RLUSD and SoFi’s SoFiUSD. These stablecoins will be enabled across a range of supported blockchain networks including Arbitrum, Base, Canton, Ethereum, Polygon, Solana, Tempo and XRPL.

“Mastercard’s move into on-chain settlement is a landmark validation that blockchain technology is ready for the world’s most critical payment infrastructure,” — said Jack McDonald, senior vice president, Stablecoins, Ripple.

“RLUSD’s inclusion in Mastercard’s global settlement network reflects growing demand for trusted, regulated stablecoins built for real-world financial use cases on public blockchains like the XRP Ledger. We’re excited to support the next evolution of faster, more flexible, always-on settlement,” — he added. 🤝

🤑🤑 Tokentus Investment CEO Oliver Michel Says XRP Is His Biggest Crypto Holding, Backs XRPL and Stellar for Tokenization Boom

🇩🇪 German financial analyst just disclosed that XRP and XLM represent his two largest cryptocurrency holdings. Michel noted that both assets rank as top allocations in his personal portfolio as well as in the holdings of Tokentus Investment AG.

“XRP is my biggest position. And XLM is also my second-biggest,” — Michel said.

📄 Meanwhile, Michel stressed that the financial industry is adopting a multi-chain blockchain strategy for tokenization-related initiatives. To support his argument, he referenced a DTCC-related patent document that reportedly mentioned both the XRP Ledger and Stellar blockchain infrastructure.

“Everything gets tokenized. These 2 are in the blueprint.” — Michel said.

According to Michel, tokenization will fundamentally reshape global finance, while XRPL and Stellar remain among the blockchain networks best positioned to benefit from the transition. 🚀
