Dallas Federal Reserve research published Oct. 16 found that alternatives to the cash-futures…

The burn is non-refundable even when a report identifies a real vulnerability that someone else submitted first.The change narrows the route to payment for later finders compared with Firedancer’s spring audit contest. In an Oct. 16 retrospective for Jump Crypto, Ishan Bhatt partly attributes the duplicate-report problem to the team’s own review delays: researchers kept finding bugs while earlier reports waited for action.The current terms generally award the first submission about the same issue or…
