Firedancer, Jump Crypto’s independent validator software for Solana, requires researchers to burn 1 SOL to qualify for a bug bounty under terms effective Oct. 18. 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…

The company that owns the New York Stock Exchange wants people to be able to buy stocks 24/7. Given the trading volume crypto and other tokenized assets have seen in the past year or so, the decision to introduce stock tokens comes as no surprise.People want to trade all the time, and now institutions want a piece of that.

Wall Street has found a use for blockchain that involves neither memecoins nor replacing the banking system. It’s now helping institutions borrow billions between breakfast and lunch, usually because they have government bonds but not enough cash when a payment comes due.Getting a bill paid on time might be the technology’s least glamorous selling point, but banks have good reasons to care.Broadridge, a financial technology company with little of crypto’s celebrity, says its distributed-ledger repo platform processed an average of $359 billion a day in September, or $7.5 trillion across the month.Its system helps institutions finance securities, move collateral, and…
