Bitcoin mining company Marathon Digital is looking to partner with blockchain developers to build a Bitcoin L2 cross-border payment solution。Julian Duran, the company's head of side chain products, revealed this information at the Bitcoin 2024 conference on July 26。Duran said cross-border payments are "the biggest use case for blockchain, especially Bitcoin."。He noted that in emerging markets, the average cost of sending money abroad is 8 to 10 per cent of the value of the transaction, and settlement usually takes 3-4 days.。In contrast, Bitcoin transfers are typically completed in 10 minutes, while a two-tier solution may be faster.。Marathon is also focusing on the real asset tokenization (RWA) space, having begun plans to tokenize whiskey barrels in the US and working 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 bitcoins worth over $1 billion.。In July alone, the company bought about $100 million worth of bitcoins.。
