Mixin Network has confirmed a report from SlowMist, a blockchain security consultancy, that it has been hacked for nearly $200 million.

“In the early morning of September 23…the database of Mixin Network's cloud service provider was attacked by hackers, resulting in the loss of some assets on the mainnet,” Mixin Network said in a statement. “The funds involved are approximately US$200 million.”

Mixin Network is a service similar to a layer-2 protocol, designed to make cross-chain transfers cheaper and more efficient.

But the problem with this, as many have pointed out on Twitter, is that it's reliant on a centralized database, creating a single point of failure.

According to a monthly report from July, the top 100 assets on the Mixin Network have a value of just over $1.1 billion.

The firm reports that there were 663,489 unique monthly transactions of bitcoin (BTC) and 179,647 ether (ETH) transactions during July.
