Canton Of Schwyz
The canton of Schwyz (german: Kanton Schwyz rm, Chantun Sviz; french: Canton de Schwytz; it, Canton Svitto) is a canton in central Switzerland between the Alps in the south, Lake Lucerne to the west and Lake Zürich in the north, centred on and named after the town of Schwyz. It is one of the founding cantons of Switzerland; Switzerland's name is derived from the name of the canton, and the flag of Switzerland from its coat of arms. For the history of the name, see Schwyz. The Swiss Federal Charter is on display in Schwyz. Northeast of the town of Schwyz is Einsiedeln Abbey. History Prehistory to the Roman era The earliest traces of humans in Schwyz are from the Upper Paleolithic and Early Mesolithic, or about 12,500 BC. An excavation of the karst caves in the valley of the Muota river (''Muotatal'') revealed numerous sites, some dating to the Younger Dryas period (c. 10,000 BC). The alpine meadows at Bödmeren, Twärenen and Silberen were Stone Age hunter-gather ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Distributed Computing
A distributed system is a system whose components are located on different networked computers, which communicate and coordinate their actions by passing messages to one another from any system. Distributed computing is a field of computer science that studies distributed systems. The components of a distributed system interact with one another in order to achieve a common goal. Three significant challenges of distributed systems are: maintaining concurrency of components, overcoming the lack of a global clock, and managing the independent failure of components. When a component of one system fails, the entire system does not fail. Examples of distributed systems vary from SOA-based systems to massively multiplayer online games to peer-to-peer applications. A computer program that runs within a distributed system is called a distributed program, and ''distributed programming'' is the process of writing such programs. There are many different types of implementations for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Network
A computer network is a set of computers sharing resources located on or provided by network nodes. The computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network can include personal computers, servers, networking hardware, or other specialised or general-purpose hosts. They are identified by network addresses, and may have hostnames. Hostnames serve as memorable labels for the nodes, rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol. Computer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth, communications ...

Algorithm
In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. More advanced algorithms can perform automated deductions (referred to as automated reasoning) and use mathematical and logical tests to divert the code execution through various routes (referred to as automated decision-making). Using human characteristics as descriptors of machines in metaphorical ways was already practiced by Alan Turing with terms such as "memory", "search" and "stimulus". In contrast, a heuristic is an approach to problem solving that may not be fully specified or may not guarantee correct or optimal results, especially in problem domains where there is no well-defined correct or optimal result. As an effective method, an algorithm can be expressed within a finite amount of spac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bitcoin
Bitcoin ( abbreviation: BTC; sign: ₿) is a decentralized digital currency that can be transferred on the peer-to-peer bitcoin network. Bitcoin transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. The cryptocurrency was invented in 2008 by an unknown person or group of people using the name Satoshi Nakamoto. The currency began use in 2009, when its implementation was released as open-source software. The word "''bitcoin''" was defined in a white paper published on October 31, 2008. It is a compound of the words ''bit'' and ''coin''. The legality of bitcoin varies by region. Nine countries have fully banned bitcoin use, while a further fifteen have implicitly banned it. A few governments have used bitcoin in some capacity. El Salvador has adopted Bitcoin as legal tender, although use by merchants remains low. Ukraine has accepted cryptocurrency donations to fund the resistance to the 2022 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prize For Innovation In Distributed Computing
The Prize for Innovation in Distributed Computing (also called SIROCCO award) is an award presented annually at the conference International Colloquium on Structural Information and Communication Complexity (SIROCCO) to a living individual (or individuals) who have made a major contribution to understanding "the relationships between information and efficiency in decentralized computing", which is main area of interest for this conference. The award recognizes innovation, in particular, it recognizes inventors of new ideas that were unorthodox and outside the mainstream at the time of their introduction. There are two restrictions for being eligible for this award: (1) The original contribution must have appeared in a publication at least five years before the year of the award, (2) One of the articles related to this contribution and authored by this candidate must have appeared in the proceedings of SIROCCO.

Blockchain
A blockchain is a type of distributed ledger technology (DLT) that consists of growing lists of records, called ''blocks'', that are securely linked together using cryptography. 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). The timestamp proves that the transaction data existed when the block was created. 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 irreversible in that, once they are recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks. 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 consen ...
