[Bitcoin blockchain Liquid was hacked and lost US$320 million, and about 4,000 Bitcoins were stolen] On September 7, a Bitcoin blockchain used by many cryptocurrency exchanges was hacked, resulting in losses of US$320 million. It became the latest in a series of recent thefts that have shaken the outside world's confidence in the security of digital assets. Liquid Network, which develops a blockchain designed to speed up transactions, noted in an X post that its Liquid Federation wallet held about 4,200 bitcoins, of which about 4,000 were stolen. The hack is the latest in a string of recent incidents that have thrust cryptocurrency cybersecurity issues into the spotlight. Just last week, an attacker stole $6 million from a digital asset lending platform associated with Crypto.com. In August, the popular Bitcoin cold wallet Coldcard was hacked, which also raised questions about how to store this digital asset in the most secure way.
