Here’s what happened in crypto today

Today in crypto, US stablecoin legislation moves closer to a Senate vote. Meanwhile, Ukraine eyes adding cryptocurrencies to its national reserves, and a proposed Bitcoin software update stirs community debate.GENIUS stablecoin bill passes key vote, advances in US SenateIn a 68-30 vote, the US Senate chose to advance the Guiding and Establishing National Innovation for US Stablecoins, or GENIUS Act, more than a month after it was introduced.Speaking from the Senate floor on Wednesday, Majority Leader John Thune urged members of Congress to support the bill, echoing many of US President Donald Trump’s talking points on digital assets, including that the legislation would help make the US the “crypto capital of the world.”'A majority of senators, including several Democrats, voted to invoke cloture for the bill, setting it up for debate and a full floor vote before potentially sending it to the House of Representatives for further consideration.“We want to bring cryptocurrency into the mainstream, and the GENIUS Act will help us do that,” said Thune.Crypto asset reserve bill lands in Ukraine’s parliamentUkrainian lawmakers have introduced a draft bill that would allow the National Bank of Ukraine (NBU) to include cryptocurrencies like Bitcoin in the country’s reserves.Submitted to Ukraine’s parliament, the Verkhovna Rada, on Tuesday, bill number 13356 proposes amendments to the law “On the National Bank of Ukraine” regarding the inclusion of crypto assets alongside gold and foreign currencies.While authorizing the central bank to acquire cryptocurrencies like Bitcoin as part of state reserves, the bill would not require the authority to do so, according to Yaroslav Zhelezniak, a member of parliament who confirmed the introduction of the bill on his Telegram channel.The central bank would retain full discretion over whether to allocate any portion of its reserves to crypto, how much to allocate and when to do so.“How, when and how much should be the decision of the regulator itself,” Zhelezniak said.Although leaving the final decision to the NBU, the lawmakers support the creation of a potential state crypto asset reserve as a step that will integrate the country into global financial innovations, Zhelezniak said.Bitcoin update to raise data limit on OP_RETURN functionAn upcoming Bitcoin software update will increase the data limit on a divisive function that will allow significantly more images, text and documents to be stored on the Bitcoin blockchain, Bitcoin Core developer Gloria Zhao said on Monday.The Bitcoin Core 30 update, slated for Oct. 30, will remove the 80-byte limit on the OP_RETURN function and allow each output to carry up to 4 megabytes of data. The function enabled the Ordinals craze last year, allowing Bitcoin users to post non-fungible token-like collections on Bitcoin.The slated change infuriated the conservative sect of the Bitcoin community, who argue that non-financial data clogs the blockchain with spam, while others, including the proposal‘s lead author Peter Todd, believe increasing the data limit will expand Bitcoin’s use cases beyond finance.In a statement on GitHub, Zhao said the Bitcoin Core devs favored a more hands-off approach, allowing users to utilize the chain however they choose and that preventing “certain transactions from being mined reflects a misunderstanding of the relationship between open source software users and developers.”
