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.

Ranchi

Ranchi (/ˈrɑːntʃi/ ) is the capital of the Indian state of Jharkhand, and its third most populous city of the state. Ranchi was the centre of the Jharkhand movement, which called for a separate state for the tribal regions of South Bihar, northern Orissa, western West Bengal & the eastern area of what is present-day Chhattisgarh. The Jharkhand state was formed on 15 November 2000 by carving out the Bihar divisions of Chota Nagpur and Santhal Parganas.

The name Ranchi is derived from the previous name of the Oraon village at the same site, Archi. "Archi" derives from the Oraon word for bamboo grove or stave. According to legend, after an altercation with a spirit, a farmer beat the spirit with his bamboo stave. The spirit shouted archi, archi, archi and vanished. Archi became Rachi, which became Ranchi. One of the historically significant neighborhoods of Rachi is Doranda (duran "दुरङ" means song and daah "दअः" means water in the Mundari language). Doranda lies between the Hinoo (Bhusur) & Harmoo Rivers, where the civil station, treasury and church established by the British Raj were destroyed by rebel forces during the Sepoy Mutiny.
