To misquote (and, indeed, to mispunctuate) Charles Dickens: it was the best of blockhains; it was the worst of blockchains.

This week, cryptocurrency company Wormhole lived up to its name by exposing an exploitable vulnerability that apparently allowed cybercriminals to run off with an eye-watering 120,000 Ether tokens.

Assuming a conversion rate of ETH1 = US$2800, that comes out close to $340,000,000.

You’ll find mention of this cyberheist on Wormole’s Twitter feed (@wormholecrypto), under an apparently un-ironic heading that describes the company’s business as:

Interoperability protocol powering the seamless transfer of value and information across 7 high value chains with just one integration”

“Seamless transfer” indeed!
