The post The Channel Factories We’ve Been Waiting For appeared on BitcoinEthereumNews.com. Visions of future technology are often prescient about the broad strokes while flubbing the details. The tablets in “2001: A Space Odyssey” do indeed look like iPads, but you never see the astronauts paying for subscriptions or wasting hours on Candy Crush.  Channel factories are one vision that arose early in the history of the Lightning Network to address some challenges that Lightning has faced from the beginning. Despite having grown to become Bitcoin’s most successful layer-2 scaling solution, with instant and low-fee payments, Lightning’s scale is limited by its reliance on payment channels. Although Lightning shifts most transactions off-chain, each payment channel still requires an on-chain transaction to open and (usually) another to close. As adoption grows, pressure on the blockchain grows with it. The need for a more scalable approach to managing channels is clear. Channel factories were supposed to meet this need, but where are they? In 2025, subnetworks are emerging that revive the impetus of channel factories with some new details that vastly increase their potential. They are natively interoperable with Lightning and achieve greater scale by allowing a group of participants to open a shared multisig UTXO and create multiple bilateral channels, which reduces the number of on-chain transactions and improves capital efficiency. Achieving greater scale by reducing complexity, Ark and Spark perform the same function as traditional channel factories with new designs and additional capabilities based on shared UTXOs.  Channel Factories 101 Channel factories have been around since the inception of Lightning. A factory is a multiparty contract where multiple users (not just two, as in a Dryja-Poon channel) cooperatively lock funds in a single multisig UTXO. They can open, close and update channels off-chain without updating the blockchain for each operation. Only when participants leave or the factory dissolves is an on-chain transaction…

Ripple XRP is a cryptocurrency that primarily focuses on building a decentralised payments network to facilitate low-cost and cross-border transactions. It’s a native digital currency of the Ripple network, which works as a blockchain called the XRP Ledger (XRPL). It utilised a shared, distributed ledger to track account balances and transactions.

The post China Blocks Nvidia’s RTX Pro 6000D as Local Chips Rise appeared on BitcoinEthereumNews.com. China Blocks Nvidia’s RTX Pro 6000D as Local Chips Rise China’s internet regulator has ordered the country’s biggest technology firms, including Alibaba and ByteDance, to stop purchasing Nvidia’s RTX Pro 6000D GPUs. According to the Financial Times, the move shuts down the last major channel for mass supplies of American chips to the Chinese market. Why Beijing Halted Nvidia Purchases Chinese companies had planned to buy tens of thousands of RTX Pro 6000D accelerators and had already begun testing them in servers. But regulators intervened, halting the purchases and signaling stricter controls than earlier measures placed on Nvidia’s H20 chip.

Regulators concluded that Chinese chips had reached performance levels comparable to the restricted U.S. models. This assessment pushed authorities to advise firms to rely more heavily on domestic processors, further tightening Nvidia’s already limited position in China. China’s Drive Toward Tech Independence The decision highlights Beijing’s focus on import substitution — developing self-sufficient chip production to reduce reliance on U.S. supplies. “The signal is now clear: all attention is focused on building a domestic ecosystem,” said a representative of a leading Chinese tech company. Nvidia had unveiled the RTX Pro 6000D in July 2025 during CEO Jensen Huang’s visit to Beijing, in an attempt to keep a foothold in China after Washington restricted exports of its most advanced chips. But momentum is shifting. Industry sources told the Financial Times that Chinese manufacturers plan to triple AI chip production next year to meet growing demand. They believe “domestic supply will now be sufficient without Nvidia.” What It Means for the Future With Huawei, Cambricon, Alibaba, and Baidu stepping up, China is positioning itself for long-term technological independence. Nvidia, meanwhile, faces…
