Another high-profile hack has raised more questions about the vulnerabilities of the blockchain

Ronin was a juicy target for a hacker. The blockchain project supports the wildly popular Axie Infinity video game, which with an estimated 8 million players has drawn comparisons to action-driven collecting games like Pokémon Go.
