Bitcoin mining company Marathon Digital is looking to partner with blockchain developers to build a Bitcoin L2 cross-border transfer solution. Julian Duran, the company's head of sidechain products, revealed this at the Bitcoin 2024 conference on July 26. According to Duran, cross-border transfers are "the biggest use case for blockchain, and Bitcoin in particular". He noted that in emerging markets, the average cost of sending money overseas is 8% to 10% of the transaction value, and settlement typically takes 3-4 days. In contrast, bitcoin transfers are usually completed in 10 minutes, while layer 2 solutions can be faster. Marathon is also focusing on the field of tokenization of physical assets (RWA), having started plans to tokenize whiskey barrels in the United States and partnering with an RWA platform to protect French castles. Notably, Marathon is one of the largest corporate holders of bitcoin, with a reserve of around 20,000 coins worth over $1 billion. In July alone, the company bought around $100 million worth of bitcoin.
