Ravencoin faces potential four-day transaction rollback after critical block flaw

Two dominant mining pools rebuilding the chain from before Friday's invalid block, putting deposits and withdrawals at risk of reversal.

• A critical block flaw on the Ravencoin network has put all deposits, withdrawals, and payments made since Friday at risk of permanent reversal if a competing chain built by majority mining pools prevails.
• Two mining pools controlling most of Ravencoin's hashpower are actively constructing a replacement chain originating from before the first invalid block, making a multi-day reorganisation technically feasible.
• The reorganisation window spans up to four days of confirmed transactions, an unusually large reversion scope that would affect any counterparty that treated those confirmations as final.
• Ravencoin's price fell 20% in the immediate aftermath of the exploit disclosure.
• Exchanges and custodians that processed RVN deposits or withdrawals since Friday face direct exposure if the replacement chain is adopted; halting RVN activity is the standard risk-mitigation step until chain stability is confirmed.

Itaú Unibanco joins ANBIMA tokenization pilot with OpenAssets

Brazil's largest lender will test tokenized bonds and investment funds under regulatory oversight

• Itaú Unibanco, Latin America's largest bank, has partnered with digital asset infrastructure firm OpenAssets to participate in a tokenization pilot overseen by Brazil's capital markets association ANBIMA.
• The pilot will test tokenized fixed-income securities and investment funds, marking Itaú's most direct institutional commitment to tokenized asset infrastructure to date.
• The initiative pairs OpenAssets' tokenization platform with Itaú's distribution scale, positioning the joint effort as a regulated proof-of-concept for Brazilian capital markets.
• Success in the ANBIMA pilot could accelerate broader regulatory clearance for tokenized securities in Brazil, a market where similar programmes have struggled to move from experiment to live issuance.

FlightAware sues Kalshi over unauthorized use of data in flight cancellation markets

Flight tracker seeks restraining order, citing trademark misuse and risk of market participants manipulating cancellations

• FlightAware's lawsuit alleges Kalshi built and operated flight cancellation prediction markets using FlightAware's proprietary data and trademark without permission, creating a commercial product on the back of assets FlightAware did not license.
• FlightAware is seeking a temporary restraining order that would bar Kalshi from any activities involving the flight-tracking platform, a remedy that, if granted, would immediately suspend the contested markets.
• The lawsuit raises a safety argument beyond intellectual property: FlightAware contends that financial incentives tied to cancellation outcomes could encourage unsafe tactics to cause cancellations and create the potential for disruption to air travel.
• The complaint includes trademark infringement and injury to reputation claims, and state authorities have been cited comparing Kalshi's contracts to gambling.
• The case is an early test of where liability sits when prediction markets use third-party data as settlement oracles without formal data-licensing agreements, a question that will affect how Kalshi and rival platforms structure future event contracts.
