Blockstream has patched bridge nodes on the Liquid Network after a $320 million exploit, and says funds are safe to return. The company confirmed the fix on Sunday, though it didn't say when the patch was applied or what exactly went wrong.
The $320 million exploit
The exploit hit the Liquid Network, a sidechain built for faster Bitcoin transactions. Blockstream didn't disclose how the attack worked, but the scale of the loss — $320 million — makes it one of the larger incidents in the network's history.
Bridge nodes patched
Blockstream said the bridge nodes have been patched. Those nodes are critical to moving assets between the Liquid Network and the main Bitcoin chain, so a vulnerability there could have wider implications. The company didn't provide technical details of the fix.
Funds safe to return
Blockstream said funds are safe to return, suggesting the exploit didn't permanently drain user balances. The company didn't say when withdrawals or transfers would resume, or whether any users lost money in the interim.
Security reminder
The incident highlights the need for robust security measures in blockchain systems. Even networks that have been running for years aren't immune to attacks, and the response — patching and reassuring users — is a reminder that the infrastructure is only as strong as its weakest link.
