The driverless car in the Internet of Things can ensure real-time and safe communication of the vehicle, including car start, driver confirmation, use of smart contracts to understand maintenance service information, and real-time location information to track the vehicle. In addition, the Internet of Things empowered by the blockchain will also produce high efficiency in the following eight vertical areas.\nWith the popularization of blockchain technology, companies will shift from the Internet of Things, which only generates incremental revenue, to a new production relationship that creates new business models and sources of income.\nThis will bring about the disappearance of industry islands, and there will be more and more products and services across industries. Therefore, enterprises can obtain greater value from IoT investment, thereby allowing the Internet of Things and artificial intelligence to be more widely used.",

The emphasis here is an atomic swap (Atomic Swap) principle, either two clears, or the transaction fails. Synchronous settlement between foreign exchange currencies (payment-versus-payment) also has the same meaning. This scenario should be the most popular, such as a decentralized exchange. However, the white paper of any cross-chain project will advertise that they can build a decentralized exchange, which is actually a natural thing.\n\n3) Cross-chain Oracle: The triggering and execution of the smart contract of chain A depends on the information from the oracle of chain B. Chain A needs to be able to read the events, status and other data of chain B.\n\n4) Asset Encumbrances: Assets on chain A are locked, and the unlocking conditions depend on the behavior on chain B. Similar to the mortgage of property rights in finance, the two-way anchoring in the side chain also has this meaning.\n\n5) General Cross-chain Contract (General Cross-chain Contract): For example, according to the proof of assets on chain A, B's currency is used to distribute dividends on chain B.",

      "body": "### Content\nTo solve the problems introduced in the previous section, any user on the Internet should be able to create, control, and transfer state natively—and the resulting value—to any participant without the need for any intermediary or centralized Companies come to stop them from doing this.\n\nBlockchain networks have turned this vision into reality, such as Bitcoin and Ethereum. The Encryption Project began to build their applications and services on this basis, with the goal of creating Web 3, the future version of the Internet.\n\nIn order to achieve a more fair and open network, the blockchain network operates through different layers, and its stack is as follows.\n\nState layer: The state layer is located at the top. It captures and saves the state of every activity, interaction, or event that occurs in the lower layers. The state layer is provided by the blockchain (such as Ethereum, Bitcoin), and it can be public or authorized to access.\nComputing layer: Through the computing layer, developers can interact with the state layer and give it instructions. The complexity of the instructions varies with the blockchain network. Taking Bitcoin as an example, the computing layer is a Bitcoin script, and in the case of Ethereum, the Ethereum Virtual Machine (EVM) is responsible for this task.\nComponent layer: The component layer includes those elements built on top of the computing layer. Its use cases include native cryptocurrencies, fungible and non-fungible tokens (NFT), stable coins and digital identity solutions.\nProtocol layer: In order for the component to work, developers must add functionality and create a set of standardized rules in the form of a protocol. For example, dYdX for derivatives, Kyber Network for trading, and Aave for lending.\nScalable layer: Compatible with the computing layer, the scalable layer can include side chains and other solutions to improve the performance of the blockchain network. For example, Bitcoin's Lightning Network and Ethereum's Raiden.\nUser control layer: The main functions of the user control layer include managing users' private keys and at the same time providing them with the ability to sign transactions through the state layer. For this reason, both hosting (such as AAX) and user-controlled wallets (such as MetaMask) reside in this layer.\nApplication layer: The application layer includes third-party decentralized applications (DApps) built on the above-mentioned layers. For example, this is a web application based on Ethereum's CryptoKitties game or UniSwap platform (you can connect your wallet to interact with the service).\nIn addition to the above stack, Web 3 also uses a decentralized architecture. The blockchain network is maintained by miners and stores data on thousands of computers instead of the centralized server used in the Web 2 solution.\n\nBased on this, users can have direct control over the Web 3 platform and its content, allowing native creation, preservation, and transfer of state and value, while providing access to all participants who follow each network rule.",
