LONDON (Reuters) - Hackers have stolen cryptocurrency worth almost $615 million from a blockchain project linked to popular online game Axie Infinity, the latest cyberheist to hit the digital asset sector.

Ronin, a blockchain network that lets users transfer crypto in and out of the game, said on Tuesday the theft happened on March 23 but was not detected until almost a week later.
