you have to read the attachment about blockchain and write it same the example which i attached, just write it in the word.

Blockchain set to change the public and private sectors The technology will help governments and businesses save time, effort and resources Blockchain is a growing chain of virtual blocks linked with each other using codes (cryptography). It is the latest trend among public and private sector companies. The technology is growing so fast that Middle East and Africa spending on blockchain will more than double to $80.8 million by the end of 2018 from a year earlier. But what is blockchain exactly? Bloc kchain is a growing digital chain of transactions (buying or selling) that are linked with each other using codes – making the communication safe . This creates an open record (ledger) of transactions in a fast and efficient manner. It is the technology use d behind cryptocurrencies such as Bitcoin and can work as a real -time record for history of financial transactions, contracts, physical assets and supply -chain information. In other words, the minute you send money to someone else, everyone on the chain ca n see what has happened. What makes this different from sending money through a bank is that no one person or entity is in charge of the whole chain. It is an open network and everyone in the chain can see the details of each record. Every block is encoded and can only be edited by its owner with a private key or password . If any change or edit is made , the entire chain is updated in real time so that everyone can see immediately . How does it work? Each transaction is digitally encoded to make sure it is a real transaction and that it is protected . This means digital security is maintained , while at the same time reducing operational cost and speeding up the decision -making process. It is cheaper and quicker because it does not need to go through a central b ank for checking. The UAE plans to use blockchain for digital transactions, giving each customer a unique identification number that points to their information on the secure chain. It is being used in a number of business applications and it makes sure that information and data on the blockchain cannot be hacked. The benefit to companies is that it allows everyone to see all transactions, meaning there will be no hidden or secret transactions. B lockchain technology will also help public and private sec tors save time, effort and resources , allowing them to process their transactions at their preferred time from any place. For example, Smart Dubai’s blockchain -powered Payment Reconciliation and Settlement System, which went live in October this year, allo ws transactions to be performed accurately and in real time, greatly increasing efficiency.
