Recently, according to Toyota's Blockchain Lab website, the company is actively researching how to incorporate Ethereum blockchain technology into its vehicles. This move is driven by Toyota's deep consideration of developing 'Mobile Originated Account' (MOA) tools based on ERC-4337 standards. The development of this tool aims to propel the industry towards smarter processes, particularly in advancing towards fully autonomous driving. By introducing blockchain technology, Toyota hopes to provide safer and more efficient data management and transaction processing methods for future autonomous vehicles, thereby enhancing the driving experience and overall operational efficiency. This innovative attempt not only showcases Toyota's forward-looking perspective in technology, but also opens up new paths for the entire automotive industry in its digital transformation journey.
