Despite its apparent complexity, a blockchain is just another type of database for recording transactions – one that is copied to all of the computers in a participating network.21A blockchain is thus sometimes referred to as a ‘distributed ledger’. Data in a blockchain is stored in fixed structures called ‘blocks’.

Emergence of Blockchain Technology For centuries, businesses and in some cases entire industries have been built on the simple principle of trust between multiple parties. However, this business of trust is about to be disrupted and transformed with the advent of blockchain technology.

Likewise, while Bitcoin is just one of many currencies implemented via a blockchain, it is by far the most well-known. Many recent initiatives have focussed upon the Blockchain networks, we’ll see the Internet of Value emerge. Blockchain technology and smart contracts will enable programmable money and frictionless transfers of digital assets, lowering the cost to transact and giving rise to seamless transactions between people, … 07/12/2017 08/08/2018 Blockchain Blockchain, the technology behind Bitcoin , seems to be the driving technology behind the next generation Internet, also referred to the Decentralized Web, or the Web3. The blockchain is a novel solution to the age-old human problem of trust. It provides an architecture for so-called trustless trust. It allows us to financial asset applications (like Bitcoin), blockchain technology is poised to have an impact on a wide range of sectors. The OECD is exploring the policy implications in a variety of areas including health, transportation, agriculture, environment, and supply chain management.

technology at the heart of bitcoin and other virtual cur-rencies, blockchain is an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. The ledger itself can also be programmed to trigger transactions auto-matically. (See the sidebar “How Blockchain Works.”) Blockchain technology does not introduce an entirely new paradigm. Rather, it builds on the old template of a ledger – something that is used to log transactions over a period of time (see figure 4). Traditional ledgers are owned by one entity (such as a Blockchain technology has a wide variety of use cases in insurance, and the examples discussed below are just the tip of the iceberg. Our5 aim, however, is to shed light on the possible impacts on the insurance value chain. Smart contracts A smart contract is a contract IoT technology, such as sensors and RFID tags, enable real-time data to be written on blockchain as food products pass along the supply chain.

Blockchain serves as an immutable ledger which allows transactions take place in a decentralized manner. A blockchain is a distributed ledger technology that stores information across multiple systems securely to enable peer-to-peer transactions by creating a trustworthy source of ‘truth’ disintermediating the so-called ‘intermediaries of trust’. Emergence of Blockchain Technology For centuries, businesses and in some cases entire industries have been built on the simple principle of trust between multiple parties. However, this business of trust is about to be disrupted and transformed with the advent of blockchain technology.
