Kalshi taps DoubleZero for Wall Street-style high-speed data feed

SummaryKalshi‘s order book is adding Solana-based DoubleZero’s low-latency market data feed to meet institutional demand.The DoubleZero Foundation described DoubleZeroEdge as a transport layer, sending live exchange and onchain data over dedicated fiber, distributing it simultaneously to all connected traders.The model has underpinned traditional financial exchanges, including NYSE, Nasdaq and the CME, for decades, the foundation said.  The growing presence of financial institutions in cryptocurrency brings with it increasing demand for Wall-Street style systems in digital asset markets, such as servers that offer split-second advantages when executing trades.  Kalshi is looking to meet that demand by adding Solana-based DoubleZeros low-latency market data feed to its prediction market order book.  The DoubleZero Foundation said this will provide trading firms with a machine-readable view of a prediction market for pricing, hedging and signal generation on Solana, one of the major layer-1 blockchains.  The foundation described DoubleZeroEdge as a transport layer, sending live exchange and onchain data over dedicated fiber, publishing the data and distributing it simultaneously to all connected traders.  In traditional finance (TradFi), institutions use specialized networks to access data at high speed, whereas in crypto, traders still largely rely on the internet. DoubleZero attempts to address that through a bespoke onchain system.  “This is the same distribution

Coldcard flaw exposed $116M self-custody risk: Gray

The Coldcard seed-generation failure has exposed about $116 million in Bitcoin to theft while renewing questions about how users verify the security of self-custody tools, according to TEXITcoin founder Bobby Gray.  SummaryAttackers have reportedly drained about 1,816 BTC worth $116 millionfrom more than 5,200 addresses.A firmware error left some Coldcard seeds with about 40 bits of entropyinstead of 128 bits.Gray said users who added independent dice-generated entropywere not affected by the reported attacks.Coinkite has released patched firmware, but existing vulnerable seeds require a complete wallet migration.  Bobby Gray, founder of TEXITcoin, told crypto.news that Coldcard users suffered losses because they trusted the hardware wallet to generate secure seed phrases without independently checking the source of randomness.  “Coldcard sat on a broken seed generator for five years, and it still cost people $116 million,” Gray said.  “Some of these wallets were generating seeds with as little as 40 bits of entropy instead of the 128 they promised.”  Gray said the lower entropy turned recovery phrases designed to resist brute-force attacks into targets that determined attackers could search without gaining physical access to the devices.

BitMart reserve doubts raise custody concerns: Arch CTO

BitMart‘s missing proof-of-reserves report and withdrawal complaints from two crypto projects have raised fresh questions about how customer assets are held during the exchange’s wind-down.  BitMart concerns expose verification problem  Arch Lending co-founder and CTO Himanshu Sahay said questions about withdrawals and exchange closures expose the difference between assurances offered by a platform and financial information that customers can independently check.  “Whenever questions arise around withdrawal processing or exchange wind-downs, it points to a structural gap across digital asset markets: the difference between platform-level statements and independent verification,” Sahay said in a statement to crypto.news.  Customers often have no real-time method for establishing whether an exchange holds their assets in segregated accounts or combines them with funds used for other operations, according to the executive. Uncertainty increases when withdrawals slow because customers must rely on the same company processing their requests for information about its financial condition.  Sahay said the crypto industry already has tools that can reduce such uncertainty, including third-party custodians, reserve attestations, and strict asset segregation. Their value depends on whether customers can use them to verify solvency claims before operational problems emerge.  “This isnt a new issue, but a recurring one that resurfaces whenever a platform faces operational stress.”  BitMart stated in May

Who Owns the Presidents Tweets? A Federal Lawsuit Wants an Answer

The Intercept and the Freedom of the Press Foundation filed a Truth API lawsuit against President Donald Trump on Wednesday. The case asks a federal judge to decide whether the president can sell early access to his own official statements.  The complaint, filed in the Southern District of New York, says presidential posts are government information.
