This location is most often a central computer or database system. decentralized database: A decentralized database is a database that is installed on systems that are geographically located at different locations but not linked through a data communication network. A distributed database: A distributed database is a single logical database, which is installed on a set of computers that are geographically located at different locations and linked through a data communication network. Block-chain & bit-coin: BlockChain is technology that’s enables Moving Digital coins or assets from one individual to another individual.A BlockChain, originally block chain, is a growing list of records, called blocks, which are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. By design, a blockchain is resistant to modification of the data. Bit-Coin: is a cryptocurrency, a form of electronic cash. It is a decentralized digital currency without a central bank or single administrator that can be sent from user to user on the peer-to-peer bitcoin network without the need for intermediaries. Concept and Problems: You want to be able to tell, when a data-set has changed. You need proof that/when it was (not) changed. Tamper-Evidence: a blockchain is decentralized. Thus there cannot be a single place where the blockchain is stored (that would make it centralized). Advantages: It is a Decentralized System. The Blockchain is Transparent. The Blockchain is More Secure. Faster and Cost Effective. Immutable. It Can Record Historical and Current Records In One Place. No Downtime. Disadvantages: Complexity. Size of Blockchain. Human Errors.
