Crypto Billionaire Sam Bankman-Fried suggests capping the maximum bounty for attackers at $5 million and ensuring victims made whole

His intervention comes just days after a hacker got to keep $50 million of the roughly $100 million drained from the Mango decentralized-finance application under a deal with the platform after the heist. Over $3 billion has been looted from the crypto sector this year, which is set to be a record for hacking.

Bankman-Fried, co-founder of digital-asset exchange FTX, proposed in a blog post what he called a “5-5 standard” where hackers keep either 5% of the amount they’ve taken from a protocol or $5 million, whichever is smaller.

Other key provisos are that customers must be made whole and that the hacker is acting in “good faith” and fully intended to cooperate and return most of the assets. In crypto, attackers are sometimes viewed as white-hat hackers who seek to expose vulnerabilities in return for a reward rather than to make malicious gains.

“Hacks are extremely destructive to the digital asset ecosystem,” Bankman-Fried wrote, adding his 5-5 approach would have curbed the impact of hacks “more than 98%” but that he’s still unsure what the right standard would be.
