Block chain
Block chain may refer to:
Block chain (database)
A block chain or blockchain is a permissionless distributed database based on the bitcoin protocol that maintains a continuously growing list of data records hardened against tampering and revision, even by its operators. The initial and most widely known application of block chain technology is the public ledger of transactions for bitcoin, which has been the inspiration for similar implementations often known as altchains.
Etymology
The block chain consists of blocks that hold timestamped batches of recent valid transactions. Each block includes the hash of the prior block, linking the blocks together. The linked blocks form a chain, with each additional block reinforcing those before it, thus giving the database type its name.
Model
A block chain implementation consists of two kinds of records: transactions and blocks.
Transactions
Transactions are the content to be stored in the block chain.Transactions are created by participants using the system. In the case of cryptocurrencies, a transaction is created anytime a bitcoin owner sends cryptocurrency to another.
Hindustani language
Hindustani (Hindustani: हिन्दुस्तानी,ہندوستانی[ɦɪn̪ˈd̪uːsˌt̪aːni], lit. "of Hindustan") historically also known as Hindavi, Dehlvi, and Rekhta, is the lingua franca of North India and Pakistan. It is an Indo-Aryan language, deriving primarily from the Khariboli dialect of Delhi, and incorporates a large amount of vocabulary from Sanskrit, Persian, Arabic and Chagatai. It is a pluricentric language, with two official forms, Modern Standard Hindi and Modern Standard Urdu, which are its standardised registers, and which may be called Hindustani or Hindi-Urdu when taken together. The colloquial languages are all but indistinguishable, and even though the official standards are nearly identical in grammar, they differ in literary conventions and in academic and technical vocabulary, with Urdu adopting stronger Persian, Turkic and Arabic influences, and Hindi relying more heavily on Sanskrit. Before the Partition of India, the terms Hindustani, Urdu, and Hindi were synonymous; all covered what would be called Urdu and Hindi today. The term Hindustani is still used for the colloquial language and lingua franca of North India and Pakistan, for example for the language of Bollywood films, as well as for several quite different varieties of Hindi spoken outside the Subcontinent, such as Fiji Hindi and the Caribbean Hindustani of Trinidad and Tobago, Guyana, Suriname, Jamaica and South Africa.
