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…

The post CME Group to launch Solana and XRP futures options in October appeared on BitcoinEthereumNews.com. CME Group is preparing to launch options on SOL and XRP futures next month, giving traders new ways to manage exposure to the two assets.  The contracts are set to go live on October 13, pending regulatory approval, and will come in both standard and micro sizes with expiries offered daily, monthly and quarterly. The new listings mark a major step for CME, which first brought bitcoin futures to market in 2017 and added ether contracts in 2021. Solana and XRP futures have quickly gained traction since their debut earlier this year. CME says more than 540,000 Solana contracts (worth about $22.3 billion), and 370,000 XRP contracts (worth $16.2 billion), have already been traded. Both products hit record trading activity and open interest in August. Market makers including Cumberland and FalconX plan to support the new contracts, arguing that institutional investors want hedging tools beyond bitcoin and ether. CME’s move also highlights the growing demand for regulated ways to access a broader set of digital assets. The launch, which still needs the green light from regulators, follows the end of XRP’s years-long legal fight with the US Securities and Exchange Commission. A federal court ruling in 2023 found that institutional sales of XRP violated securities laws, but programmatic exchange sales did not. The case officially closed in August 2025 after Ripple agreed to pay a $125 million fine, removing one of the biggest uncertainties hanging over the token. This is a developing story.
