The stcChain project is a blockchain-based platform that aims to revolutionize the way IoT data is managed, secured, and transacted. It is designed to provide a secure and efficient ecosystem for various industries to leverage blockchain technology. stcChain offers features such as decentralized storage, smart contracts, and a consensus mechanism to ensure data integrity and transparency. The project is committed to promoting innovation and collaboration in the blockchain space.

Hyperledger Besu is an open-source Ethereum client developed under the Apache 2.0 license and written in Java. It runs on the Ethereum public network, private networks, and test networks such as Rinkeby, Ropsten, and Görli. Besu implements Proof of Work (Ethash) and Proof of Authority (IBFT 2.0 and Clique) consensus mechanisms. You can use Besu to develop enterprise applications requiring secure, high-performance transaction processing in a private network. Besu supports enterprise features including privacy and permissioning.

The Besu client supports common smart contract and Dapp development, deployment, and operational use cases, using tools such as Truffle, Remix, and web3j. The client supports common JSON-RPC API methods such as eth, net, web3, debug, and miner.</p> <p>Besu doesn’t support key management inside the client. You can use EthSigner with Besu to access your key store and sign transactions.

Blockchain applications are comparable to conventional software applications, except they implement a decentralized architecture and cryptoeconomic systems to increase security, foster trust, tokenize assets, and design new network incentives. Here are over 90 Ethereum apps that are currently being used across the Ethereum blockchain ecosystem, from prediction markets to smart legal agreements.

EthSigner is an open-source, client-agnostic, Ethereum transaction signer developed under the Apache 2.0 license and written in Java. EthSigner separates private key management from transaction validation by signing transactions using a private key that can be secured in a variety of cloud providers, or encrypted on a local disk.

The Economy of Things offers an equalized opportunity to access IoT data so that a much broader range of AI practitioners can create value from it, and in turn accelerate the transformation towards cognitive cities. EoT can be used as a foundational substrate to power a new ecosystem of data marketplaces, and more broadly, data sharing for the public good.

1. Simplify privacy compliance for organizations - Personal data ownership remains in the hands of people, while value creation from that data by companies is unaffected. It makes any process involving private data compliant with the most restrictive data protection frameworks. 2. Create new revenue streams - Anyone who owns data, no matter how much and what kind, can earn revenue by granting access to those willing to pay. This applies to individuals and organizations. 3. Unlock data taps - The ability to monetize data introduces an incentive to share data. This increases the amount of data breaking free from silos, ready to be blended and transformed to create value. 4. Make IoT data available - With more IoT data available to use for City Planners and AI Scientists, data models will get more accurate, increasing the market value of data products & smart city services. The ability to easily search and find data from a global corpus removes barriers and friction to match data supply and demand. 5. Liberalize IoT data workflows - With IoT data and data services organized in markets, data science workflows can be redesigned from scratch. Market actors will be able to compete and collaborate on each activity in the value chain. 6. Seed the New Data Economy - Data markets will be made 100% liquid. While it is difficult to describe how the New Data Economy will look like, moving from an archaic ownership model to a completely liberalized economy is expected to drive disruption. 7. The wave of change coming to data science and AI with the adoption of blockchain & IoT technologies is likely to be as big as the one that came with the adoption of the internet.

stcChain aims to contribute to smart cities innovation by leveraging blockchain technology to address key challenges faced by modern urban environments. Some of the goals of stcChain in the context of smart cities innovation include: 1. In Data Management: stcChain offers secure and decentralized IoT data storage solutions, making it easier for smart cities to manage vast amounts of data generated by IoT devices, sensors, and other sources. 2. In Transparency and Trust: By utilizing blockchain technology, stcChain helps establish transparent and trustworthy systems for various smart city applications, such as transportation, energy management, and public services. 3. In Efficiency and Security: stcChain enhances the efficiency and security of transactions within smart cities by providing a reliable and tamper-proof platform for conducting and recording transactions. 4. In Interoperability: stcChain aims to promote interoperability among different systems and applications in smart cities, enabling seamless IoT data sharing and communication between various stakeholders. Overall, stcChain seeks to be a catalyst for innovation in smart cities by offering cutting-edge blockchain solutions that can enhance sustainability, resilience, and quality of life in urban environments.

Besu includes a command line interface and JSON-RPC API for running, maintaining, debugging, and monitoring nodes in an Ethereum network. You can use the API via RPC over HTTP or via WebSockets. Besu also supports Pub/Sub. The API supports typical Ethereum functionalities such as:</p> <p>Ether mining<br /> Smart contract development<br /> Decentralized application (Dapp) development.

A blockchain is a distributed, cryptographically-secure database structure that allows network participants to establish a trusted and immutable record of transactional data without the need for intermediaries. A blockchain can execute a variety of functions beyond transaction settlement, such as smart contracts. Smart contracts are digital agreements that are embedded in code and that can have limitless formats and conditions. Blockchains have proven themselves as superior solutions for securely coordinating data, but they are capable of much more, including tokenization, incentive design, attack-resistance, and reducing counter party risk. The very first blockchain was the Bitcoin blockchain, which itself was a culmination of over a century of advancements in cryptography and database technology.

Blockchain technology has a wide variety of benefits, for both global enterprises and local communities. The most commonly cited benefits of a blockchain are trusted data coordination, attack-resistance, shared IT infrastructure, tokenization, and built-in incentivization.

The Economy of Things is the result of the emergence and combination of two fields: the Internet of Things and Blockchain Technology. It allows verified connected devices, vehicles, smart street furniture and machines to transact seamlessly and securely without human intervention, but with full owner control.

The Economy of Things is created when new value is extracted from the Internet of Things. This means that physical assets are turning into Digital Assets that can participate in new disruptive digital markets, liquefying the physical world. Individuals, as well as organizations, control and can provide access to their IoT data streams without worrying about losing ownership and privacy. They can earn a revenue from their data and decide exactly what data streams are shared, to whom, and how. It also gives them visibility of how their data is accessed and used by apps, services, and other companies.
