first_img Petrobras tests Cardano, tracking sustainable aviation fuel and diesel

According to CoinDesk, Brazil's state-controlled energy company Petrobras is testing the Cardano blockchain to track statements related to low-carbon fuels.The Cardano Foundation announced two research projects on Wednesday, one focusing on sustainable aviation fuel, which is a low-carbon aviation fuel alternative that can be used in existing aircraft and airports, and the other on Diesel R, which is diesel produced by Petrobras using renewable materials such as vegetable oils and animal fats.The aviation fuel project targets the book-and-claim model in green fuel sales: airlines can pay for the environmental benefits of sustainable fuel, even if the fuel itself is used elsewhere. This model requires recording the benefit attribution and claiming time to avoid double counting the same emissions reduction.The application records the source, recipient, and claiming time of each benefit through Cardano. In real scenarios, passengers can input their departure and destination airports to calculate the corresponding fuel benefits and receive a certificate linking their quota to the original fuel certificate. The diesel project records information on fuel production, transportation, and usage, compiling it into a complete fuel process history, which helps companies report Scope 3 emissions.Frederik Gregaard, CEO of the Cardano Foundation, stated that Brazil has been one of the most stable adopters of Cardano, from government agencies like SERPRO to industrial sectors like SENAI, and Petrobras continues to value the on-chain traceability and transparency.He mentioned that with x402 landing on Cardano and Fireblocks increasing support for Cardano native tokens, institutional interest continues to grow.

Analysis: The passage of the CLARITY Act is expected to drive BTC's strength against the trend, fueled by the logic of currency depreciation and regression

According to CoinDesk, amidst the impact of the Middle East conflict on global stock markets and commodities, Bitcoin has risen against the trend, reaching a one-month high and helping to revitalize the overall cryptocurrency market. After falling nearly 50% from its historical high in October last year, Bitcoin had once been in the oversold territory.Following the outbreak of this round of key conflicts, traditional assets have significantly declined, while BTC's relatively strong performance has reinforced its temporary "safe-haven narrative." Market analysis suggests that this round of increase is mainly driven by three factors:The return of the "fiat currency depreciation" logic, as the intensifying Middle East conflict exacerbates global fiscal pressures, which may lead to expectations of more easing and deficit expansion, strengthening the "fiat currency depreciation" narrative, prompting some funds to be reallocated to digital assets.There may be expectations for a de-escalation in the Middle East situation. Although there has been no response from the U.S., this news has strengthened market expectations that "the conflict may not spiral out of control for a long time," supporting the recovery of risk asset sentiment.The CLARITY Act is close to being passed, aiming to clarify the legal status of stablecoins, which is beneficial for the cryptocurrency market.
