<p>Unveiled last week as a part of Toyota’s Mobility 3.0 concept, the project centers around exploring mobility as a smart account on the <a href="https://btc-pulse.com/solana-based-jupiter-spark-controversy-collaborating/" rel="noopener noreferrer nofollow">blockchain</a>. Introducing vehicle mobility onto public blockchains brings tokenizing rights, making a car function as a completely independent service entity.</p>
<p>“The most extreme scenario suggested by these features is fully autonomous driving in the future,” <a href="https://www.toyota-blockchain-lab.org/library/how-to-introduce-mobility-into-the-public-blockchain" target="_blank" rel="noopener noreferrer nofollow">Toyota’s blog post read</a>. Autonomous mobility no longer requires human operation as all rights are handled in the on-chain world, it added.</p>
<h2 class="wp-block-heading" id="every-toyota-car-has-its-own-account-on-ethereum">Every Toyota Car Has Its Own Account on Ethereum</h2>
<p>Toyota is exploring how to design MOA, based on the Account Abstraction standard ERC-4337 on Ethereum. Interestingly, the car behemoth noted that such an MOA design on ERC-4337 makes sure that the blockchain account for a car is retained, even if the private key is lost.</p>
<p>“Account Abstraction separates the authentication process from key management, ensuring that the account itself is retained even if the private key is lost,” Toyota wrote. “This enables safer and more flexible account management.”</p>
<p>Further, leveraging Ethereum will also manage information about the car, such as usage history, more transparently and efficiently.</p>
<h2 class="wp-block-heading" id="bridging-vehicle-id-systems-with-on-chain-addresses">Bridging Vehicle ID Systems with On-Chain Addresses</h2>
<p>Besides, ERC-4337 allows the “deterministic setting of an address before the account is deployed.” This helps in bridging the existing vehicle ID systems with on-chain addresses.</p>
<p>Toyota also proposed a key token concept, which complies with the <a href="https://btc-pulse.com/meta-reportedly-cuts-metaverse-20-as-q2-earnings/" rel="noopener noreferrer nofollow">NFT </a>standard and holds car owner information and “usage rights.”</p>
<p>“By expressing car access as NFTs tied to MOA, permissions can be controlled simply by transferring NFTs,” it noted. “This allows handling ‘usage rights’ digitally without being conscious of the hardware, making it easier for developers to realize services such as car sharing.”</p>
<h2 class="wp-block-heading" id="toyota-s-blockchain-lab-initiative">Toyota’s Blockchain Lab Initiative</h2>
<p>Toyota’s Blockchain Lab has proposed the mobility-oriented account-based project for vehicles. The lab is a virtual organization established in 2019 within the Toyota Group to promote the use of blockchain.</p>
