Subset of the Internet<\/b><\/div>\n<\/div>\n<div>\n<div style=\"text-align: justify;\">A blockchain is a network of nodes(also computing devices) that work together to manage data and transactions on those data. This is the same way the internet is made up of computers that share information.<br \/>Now, since blockchain is based on the Internet, we can see it as a more powerful and secure <b>subset of the Internet.&nbsp;<\/b><\/div>\n<\/div>\n<p><ins data-ad-client=\"ca-pub-7041870931346451\" data-ad-format=\"fluid\" data-ad-layout=\"in-article\" data-ad-slot=\"1097581601\" style=\"display: block; text-align: center;\"><\/ins> <\/p>\n<div>\n<div style=\"text-align: justify;\">Unlike the internet which contains all manner of junk, the blockchain holds highly sensitive financial records(ledger) which have been described a incorruptible(we&#8217;ll come to that in a moment).<\/div>\n<\/div>\n<div>\n<div style=\"text-align: justify;\"><\/div>\n<\/div>\n<div>\n<div style=\"text-align: justify;\"><b>How Does It Work<\/b><\/div>\n<\/div>\n<div>\n<div style=\"text-align: justify;\">A unit of data in a blockchain is called <b>block<\/b>. So the blockchain is an inter-network of all the blocks. Transactions are carried out on by those nodes. Transactions can be requested by user just like you and me. Transactions are what the name is, just like &#8216;bank transactions&#8217; which includes opening a new account, making a withdrawal, paying into the account and so on.<\/div>\n<p><\/p>\n<table align=\"center\" cellpadding=\"0\" cellspacing=\"0\" style=\"margin-left: auto; margin-right: auto; text-align: center;\">\n<tbody>\n<tr>\n<td style=\"text-align: center;\"><a href=\"https:\/\/2.bp.blogspot.com\/-It9ZOsLJ1x0\/WWX3aGITRII\/AAAAAAAAAIs\/oiWA8jeP_WoHc80am9X9QcbT7nZ44AaqwCLcBGAs\/s1600\/Blockchain2.jpg\" style=\"margin-left: auto; margin-right: auto;\"><img decoding=\"async\" loading=\"lazy\" alt=\"How Blockchain Works\" border=\"0\" data-original-height=\"402\" data-original-width=\"706\" height=\"364\" src=\"https:\/\/2.bp.blogspot.com\/-It9ZOsLJ1x0\/WWX3aGITRII\/AAAAAAAAAIs\/oiWA8jeP_WoHc80am9X9QcbT7nZ44AaqwCLcBGAs\/s640\/Blockchain2.jpg\" title=\"How Blockchain Works\" width=\"640\" \/><\/a><\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: center;\">Figure 1: How Blockchain Works &#8211; Part 2<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><\/div>\n<div>\n<div style=\"text-align: justify;\">The Life Cycle of a transaction in a Blockchain is show in Figure 1 from when a user requests for a transaction to when the transaction is complete.

Transaction is Requested<\/b><br \/>A&nbsp; transaction may be transfer of bitcoin to another account(user wallet), new user joining the system, buying\/selling transaction etc. So in step one, a transaction is requested by a user which could be you or me.<\/p>\n<p><b>2. Request is Broadcast<\/b><br \/>&nbsp;Since the database is a distributed database, all nodes in the network needs to get the transaction request (in centralized database, your a bank teller handles independent of other bankers\/customers). Simply put, everyone in the network\/blockchain gets the request.<\/p>\n<p><b>3. All Nodes Confirms and Validates the Request<\/b><br \/>This is where the system supersedes conventional system in the aspect of security. Before the transaction is entered, all node has to confirm and verify it. Making sure its authentic. The distributed database system handles this. It takes &#8220;some time&#8221;, but it has to be done to ensure the integrity and consistency of the system.<\/p>\n<p><b>4. A Block is Created (<\/b>This process is called<b> Mining)<\/b><br \/>When all nodes have reached a consensus that the transaction is legitimate and can be accepted, then a block can be created. A number of confirmed transactions is combined and recorded together as a block (a block is a combination of two or more individual transactions)<\/p>\n<p><b>5. Block is Recorded<\/b><br \/>The recording is actually done in this step. In the previous step, a block is created by combining the transactions. In this step, this new block in recorded permanently to the chain.<\/p>\n<p><ins data-ad-client=\"ca-pub-7041870931346451\" data-ad-format=\"fluid\" data-ad-layout=\"in-article\" data-ad-slot=\"1097581601\" style=\"display: block; text-align: center;\"><\/ins> <b>6.

Allows transactions to be carried out without the delays and bureaucratic nature of having a middle-entity such as banks<\/div>\n<div style=\"text-align: justify;\">2.
