Blockchain-based Service Network
The Blockchain-based Service Network (BSN) is a backend architecture in China for developing and managing blockchain-based applications, and is split into Chinese and International uses. BSN China, designed as the backbone of China's blockchain strategy, was established in 2018 and launched in 2020 by the State Information Center under the National Development and Reform Commission of China, China Mobile, China UnionPay(state-owned payment and settlement provider), and a technology architect. BSN International operates under the Singapore-based BSN Foundation. The BSN integrates both private and public blockchain frameworks and cloud service providers to build the underlying development and production environment, where enterprises, governmental bodies, and financial institutions can build Blockchain-as-a-Service Systems and blockchain applications while being compliant with China's regulations of non-cryptocurrencies. BSN International draws on Amazon Web Services data center ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frontend And Backend
In software development, frontend refers to the presentation layer that users interact with, while backend involves the data management and processing behind the scenes, and full-stack development refers to mastering both. In the client–server model, the Client (computing), client is usually considered the frontend, handling user-facing tasks, and the Server (computing), server is the backend, managing data and logic. Some presentation tasks may also be performed by the server. Introduction In software architecture, there may be many Abstraction layer, layers between the hardware and End-user (computer science)#End user, end user. The ''front'' is an abstraction, simplifying the underlying component by providing a user-friendly interface, while the ''back'' usually handles data storage and business logic. Examples E-commerce Website: The ''frontend'' is the user interface (e.g., product pages, search bar), while the ''backend'' processes payments and updates inventory. Bank ...

Permissioned Blockchain
The blockchain is a distributed ledger with growing lists of records (''blocks'') that are securely linked together via cryptographic hashes. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree, where data nodes are represented by leaves). Since each block contains information about the previous block, they effectively form a ''chain'' (compare linked list data structure), with each additional block linking to the ones before it. Consequently, blockchain transactions are resistant to alteration because, once recorded, the data in any given block cannot be changed retroactively without altering all subsequent blocks and obtaining network consensus to accept these changes. Blockchains are typically managed by a peer-to-peer (P2P) computer network for use as a public distributed ledger, where nodes collectively adhere to a consensus algorithm protocol to add and validate new transaction block ...

Cloud Computing
Cloud computing is "a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand," according to International Organization for Standardization, ISO. Essential characteristics In 2011, the National Institute of Standards and Technology (NIST) identified five "essential characteristics" for cloud systems. Below are the exact definitions according to NIST: * On-demand self-service: "A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider." * Broad network access: "Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations)." * Pooling (resource management), Resource pooling: " The provider' ...

Interoperability
Interoperability is a characteristic of a product or system to work with other products or systems. While the term was initially defined for information technology or systems engineering services to allow for information exchange, a broader definition takes into account social, political, and organizational factors that impact system-to-system performance. Types of interoperability include syntactic interoperability, where two systems can communicate with each other, and cross-domain interoperability, where multiple organizations work together and exchange information. Types If two or more systems use common data formats and communication protocols then they are capable of communicating with each other and they exhibit ''syntactic interoperability''. XML and SQL are examples of common data formats and protocols. Low-level data formats also contribute to syntactic interoperability, ensuring that alphabetical characters are stored in the same ASCII or a Unicode format in all ...

Digital Currency
Digital currency (digital money, electronic money or electronic currency) is any currency, money, or money-like asset that is primarily managed, stored or exchanged on digital computer systems, especially over the internet. Types of digital currencies include cryptocurrency, virtual currency and central bank digital currency. Digital currency may be recorded on a distributed database on the internet, a centralized electronic computer database owned by a company or bank, within digital files or even on a stored-value card. Digital currencies exhibit properties similar to traditional currencies, but generally do not have a classical physical form of fiat currency historically that can be held in the hand, like currencies with printed banknotes or minted coins. However, they do have a physical form in an unclassical sense coming from the computer to computer and computer to human interactions and the information and processing power of the servers that store and keep track o ...

US House Of Representatives
The United States House of Representatives is a chamber of the bicameral United States Congress; it is the lower house, with the U.S. Senate being the upper house. Together, the House and Senate have the authority under Article One of the U.S. Constitution to pass or defeat federal legislation, known as bills. Those that are also passed by the Senate are sent to the president for signature or veto. The House's exclusive powers include initiating all revenue bills, impeaching federal officers, and electing the president if no candidate receives a majority of votes in the Electoral College. Members of the House serve a fixed term of two years, with each seat up for election before the start of the next Congress. Special elections also occur when a seat is vacated early enough. The House's composition was established by Article One of the United States Constitution. The House is composed of representatives who, pursuant to the Uniform Congressional District Act, sit ...

Hyperledger
Hyperledger (or the Hyperledger Project) is an umbrella project of open source blockchains and related tools that the Linux Foundation started in December 2015. IBM, Intel, and SAP Ariba have contributed to support the collaborative development of blockchain-based distributed ledgers. It was renamed the Hyperledger Foundation in October 2021. In September 2024, Hyperledger Foundation and Trust Over IP Foundation became part of the newly launched Linux Foundation Decentralized Trust. History and aims In December 2015, the Linux Foundation announced the creation of the Hyperledger Project. The founding project members were announced in February 2016, with ten further members and the governing board announced a month later on March 29. On May 19, Brian Behlendorf was appointed the project’s executive director. The project’s objective is to advance cross-industry collaboration by developing blockchains and distributed ledgers, focusing on improving the systems’ performance ...
