Zerocoin Protocol
Zerocoin is a privacy protocol proposed in 2013 by Johns Hopkins University professor Matthew D. Green and his graduate students, Ian Miers and Christina Garman. It was designed as an extension to the bitcoin network, Bitcoin protocol that would improve Bitcoin transactions' anonymity by having coin-mixing capabilities natively built into the protocol. Zerocoin is not currently compatible with Bitcoin. History Due to the public nature of the blockchain, users may have their privacy compromised while interacting with the network. To address this problem, third-party management, third-party Cryptocurrency tumbler, coin mixing service can be used to obscure the trail of cryptocurrency transactions. In May 2013, Matthew D. Green and his graduate students (Ian Miers and Christina Garman) proposed the Zerocoin protocol where cryptocurrency transactions can be anonymized without going through a trusted third-party, by which a coin is destroyed then minted again to erase its history.

Privacy Protocol
Privacy protocols are guildlines intended to allow computation while still protecting the individuals involved. It can be developed from just two individuals trying to discover if they both know the same secret, without leaking information about the secret itself. In this case, after the protocol runs, both individuals will either know that they share the secret, or know that they do not share it; they will have gained no additional information about the other's secret. Examples of privacy protocols For example, say the secret is a name of a person. One protocol is to use a random phone number, such as 555-111-2222, then replace the last n digits of the phone number with the secret such as 555-111-JOHN. Then the first person calls the number and leaves a message with the person on the other end for the second person. Next the second person calls the number of their secret and asks if there are any messages for him. One issue with this protocol is that the phone number created ...

Prime Number
A prime number (or a prime) is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, or , involve 5 itself. However, 4 is composite because it is a product (2 × 2) in which both numbers are smaller than 4. Primes are central in number theory because of the fundamental theorem of arithmetic: every natural number greater than 1 is either a prime itself or can be factorized as a product of primes that is unique up to their order. The property of being prime is called primality. A simple but slow method of checking the primality of a given number n, called trial division, tests whether n is a multiple of any integer between 2 and \sqrt. Faster algorithms include the Miller–Rabin primality test, which is fast but has a small chance of error, and the AKS primality test, which always pr ...

Egalitarianism
Egalitarianism (), or equalitarianism, is a school of thought within political philosophy that builds from the concept of social equality, prioritizing it for all people. Egalitarian doctrines are generally characterized by the idea that all humans are equal in fundamental worth or moral status. Egalitarianism is the doctrine that all citizens of a state should be accorded exactly equal rights. Egalitarian doctrines have motivated many modern social movements and ideas, including the Enlightenment, feminism, civil rights, and international human rights. The term ''egalitarianism'' has two distinct definitions in modern English, either as a political doctrine that all people should be treated as equals and have the same political, economic, social and civil rights, or as a social philosophy advocating the removal of economic inequalities among people, economic egalitarianism, or the decentralization of power. Sources define egalitarianism as equality reflecting the natural st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphics Card
A graphics card (also called a video card, display card, graphics adapter, VGA card/VGA, video adapter, display adapter, or mistakenly GPU) is an expansion card which generates a feed of output images to a display device, such as a computer monitor. Graphics cards are sometimes called discrete or dedicated graphics cards to emphasize their distinction to Graphics processing unit#Integrated graphics, integrated graphics. A graphics processing unit that performs the necessary computations is the main component of a graphics card, but the acronym "GPU" is sometimes also used to refer to the graphics card as a whole. Most graphics cards are not limited to simple display output. The graphics processing unit can be used for additional processing, which reduces the load from the central processing unit. Additionally, computing platforms such as OpenCL and CUDA allow using graphics cards for General-purpose computing on graphics processing units, general-purpose computing. Applications o ...

Central Processing Unit
A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. This contrasts with external components such as main memory and I/O circuitry, and specialized processors such as graphics processing units (GPUs). The form, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the fetching (from memory), decoding and execution (of instructions) by directing the coordinated operations of the ALU, registers and other co ...

Application-specific Integrated Circuit
An application-specific integrated circuit (ASIC ) is an integrated circuit (IC) chip customized for a particular use, rather than intended for general-purpose use, such as a chip designed to run in a digital voice recorder or a high-efficiency video codec. Application-specific standard product (ASSP) chips are intermediate between ASICs and industry standard integrated circuits like the 7400 series or the 4000 series. ASIC chips are typically fabricated using metal-oxide-semiconductor (MOS) technology, as MOS integrated circuit chips. As feature sizes have shrunk and design tools improved over the years, the maximum complexity (and hence functionality) possible in an ASIC has grown from 5,000 logic gates to over 100 million. Modern ASICs often include entire microprocessors, memory blocks including ROM, RAM, EEPROM, flash memory and other large building blocks. Such an ASIC is often termed a SoC (system-on-chip). Designers of digital ASICs often use a hardware descrip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
InterPlanetary File System
The InterPlanetary File System (IPFS) is a protocol, hypermedia and file sharing peer-to-peer network for storing and sharing data in a distributed file system. IPFS uses content-addressing to uniquely identify each file in a global namespace connecting IPFS hosts. IPFS can among others replace the location based hypermedia server protocols and to distribute the World Wide Web.YoutubeStanford Seminar - "IPFS and the Permanent Web"- Juan Benet of Protocol LabsQuote: "...The InterPlanetary File System (IPFS) is a new hypermedia distribution protocol, to complement--and eventually replace--HTTP. It improves the security, performance, operation modes, and data friendliness of the Web. In particular, it yields a powerful new model, where websites and web applications are decoupled from origin servers, are distributed trustlessly through the network, and are encrypted, authenticated, and executed safely..." Design IPFS allows users to host and receive content in a manner simila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Democrat Party (Thailand)
The Democrat Party ( th, พรรคประชาธิปัตย์; ) is a Thai political party. The oldest party in Thailand, it was founded as a royalist party, and now upholds a conservative and pro-market position. The Democrat Party made its best showings in parliament in 1948, 1976, and 1996. It has never won an outright parliamentary majority. The party's electoral support bases are southern Thailand and Bangkok, although election results in Bangkok have fluctuated widely. Since 2004, Democrat candidates won three elections for the governorship of Bangkok. From 2005 to 2019, the Democrat Party was led by Abhisit Vejjajiva, former prime minister. Names The Thai name of the party, ''Prachathipat'' (ประชาธิปัตย์), is derived from the word ''prachathipatai'' (ประชาธิปไตย) which means 'democracy', 'democratic' or 'democrat'. The party said it wanted the term to mean the people in whom democracy is vested. History P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Private Network
A virtual private network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. The benefits of a VPN include increases in functionality, security, and management of the private network. It provides access to resources that are inaccessible on the public network and is typically used for remote workers. Encryption is common, although not an inherent part of a VPN connection. A VPN is created by establishing a virtual point-to-point connection through the use of dedicated circuits or with tunneling protocols over existing networks. A VPN available from the public Internet can provide some of the benefits of a wide area network (WAN). From a user perspective, the resources available within the private network can be accessed remotely. Types Virtual private networks may be classified into several categories: ;Remote acce ...
