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 MoneyGram launches stablecoin-powered app in Colombia appeared on BitcoinEthereumNews.com. MoneyGram has launched a new mobile application in Colombia that uses USD-pegged stablecoins to modernize cross-border remittances. According to an announcement on Wednesday, the app allows customers to receive money instantly into a US dollar balance backed by Circle’s USDC stablecoin, which can be stored, spent, or cashed out through MoneyGram’s global retail network. The rollout is designed to address the volatility of local currencies, particularly the Colombian peso. Built on the Stellar blockchain and supported by wallet infrastructure provider Crossmint, the app marks MoneyGram’s most significant move yet to integrate stablecoins into consumer-facing services. Colombia was selected as the first market due to its heavy reliance on inbound remittances—families in the country receive more than 22 times the amount they send abroad, according to Statista. The announcement said future expansions will target other remittance-heavy markets. MoneyGram, which has nearly 500,000 retail locations globally, has experimented with blockchain rails since partnering with the Stellar Development Foundation in 2021. It has since built cash on and off ramps for stablecoins, developed APIs for crypto integration, and incorporated stablecoins into its internal settlement processes. “This launch is the first step toward a world where every person, everywhere, has access to dollar stablecoins,” CEO Anthony Soohoo stated. The company emphasized compliance, citing decades of regulatory experience, though stablecoin oversight remains fluid. The US Congress passed the GENIUS Act earlier this year, establishing a framework for stablecoin regulation, which MoneyGram has pointed to as providing clearer guardrails.
