BLOCK CHAIN

A blockchain,[1][2][3] originally block chain,[4][5] is a growing list of records, called blocks, that are linked using cryptography.[1][6] Each block contains a cryptographic hash of the previous block,[6] a timestamp, and transaction data (generally represented as a Merkle tree). By design, a blockchain is resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way".[7] For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for inter-node communication and validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without alteration of all subsequent blocks, which requires consensus of the network majority. Although blockchain records are not unalterable, blockchains may be considered secure by design and exemplify a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been claimed with a blockchain.[8] Blockchain was invented by a person (or group of people) using the name Satoshi Nakamoto in 2008 to serve as the public transaction ledger of the cryptocurrency bitcoin.[1] The identity of Satoshi Nakamoto is unknown. The invention of the blockchain for bitcoin made it the first digital currency to solve the double-spending problem without the need of a trusted authority or central server. The bitcoin design has inspired other applications,[1][3] and blockchains that are readable by the public are widely used by cryptocurrencies. Blockchain is considered a type of payment rail.[9] Private blockchains have been proposed for business use. Sources such as Computerworld called the marketing of such blockchains without a proper security model "snake oil".[10]

The elements: A very short introduction

This Very Short Introduction is an exciting and non-traditional approach to understanding the terminology, properties, and classification of chemical elements. It traces the history and cultural impact of the elements on humankind, and examines why people have long sought to identify the substances around them.

BLOCK CHAIN TECHNOLOGY

Immutably storing the digital representation of entities (e.g. Bitcoin) as their state changes via transactions Cryptocurrencies/Store of value - What is my account balance? Digital Identity - Who are you and how have you changed over time? Digital representation of a vehicle/Tokenization – Who owned this car over time? Tracking provenance of food or drugs – What country & postal code did this chicken come from Blockchains are not good for: Executing AI Algorithms Executing Complex planning and scheduling algorithms Real-Time Control
