Datavault AI has agreed to acquire BankWyse, a Wyoming banking institution, while promising funding substantially larger than the cash it reported at the end of June.The mismatch leaves a central question for the proposed deal: How can Datavault finance the purchase and capitalize the bank without another layer of debt or dilution?The agreement disclosed on Aug. 19 values the initial consideration at approximately $22 million, comprising $14.66 million in Datavault stock and $7.34 million in cash. BankWyse’s sellers could receive up to another $10 million if they meet milestones, split evenly between cash and stock.Separate from the purchase price, Datavault…

At USENIX Security on Aug. 12, researchers presented a Solana Proof-of-History clock attack they had disclosed privately to Solana developers in December 2025. Anza’s 50,000 SOL Alpenglow competition closed seven days later, and its rules appear to place the attack outside the scope.The paper describes a protocol-valid way for a scheduled leader to stretch its effective block window and suppress honest leaders’ proposals in a fork-assisted version. The path relies on Proof-of-History and TowerBFT, the machinery Alpenglow is intended to replace but had not yet displaced on mainnet in Agave 4.2.The finding creates both a contest-scope story and a transition-risk…

MAYAChain’s attacker moved about $1.36 million in hard assets to external chains, while the estimated impact across the network’s liquidity pools approached $11 million.The $1.36 million figure tracks assets that left the system, including roughly 20.83 BTC. The larger estimate captures a cascade inside the pools: false accounting created a huge CACAO balance, that balance became withdrawable, and CACAO’s subsequent collapse repriced the network’s remaining liquidity.Maya Protocol operates MAYAChain as a cross-chain liquidity network where users trade against pooled assets. Its CACAO token connects those markets, which allowed a failure that began in one pool to spread through the value…

Cosmos Health’s crypto treasury was down about 46% at the end of June as the Nasdaq-listed company warned that recurring losses and reliance on outside financing raised substantial doubt about its ability to continue as a going concern over the next 12 months.The company held 474.85 ETH and 15.66 BTC worth a combined $1.66 million against a $3.1 million cost basis, leaving about $1.44 million in unrealized losses.
