Primarily described in 1991, research scientists Stuart Haber and W. Scott Stornetta developed a digital system to avoid tampering with documents. The system helped stamp documents digitally and store them in blocks that are secured in a chain cryptographically. In 1992, the introduction of Merkle Trees enabled the system to add a collection of documents into a single block. This further increased the efficiency.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<figure><img decoding=\"async\" src=\"https:\/\/hh-certificates.sgp1.digitaloceanspaces.com\/blog\/wp-content\/uploads\/2022\/11\/29065846\/jpegbase64f7e35e7e81c9bad3.jpg\" alt=\"blockchain history\" width=\"483\" height=\"362\" \/>\n<p>\u00a0<\/p>\n<figcaption>Image Source: Naukri.com<\/figcaption>\n<\/figure>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>However, it was in 2008 that the concept of blockchain technology started being used for practical purposes. That purpose happened to be the transaction of digital currencies. Under the pseudonym of Satoshi Nakamoto, probably one person or a group of people worked on the first decentralized digital cryptocurrency, Bitcoin. For this purpose, they put the concept of blockchain into practice as a public ledger for transactions in 2009.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>In 2008, Satoshi Nakamoto also released a white paper on the features and characteristics of the technology. This particularly included the fact about the digital trust one can achieve through the decentralization of technology. Now, the technology has evolved and found many more cryptocurrencies for application.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>Secure transactions of digital currencies will remain the main reason for the usage of this technology for ages to come. However, the use of this technology is not just limited to currencies anymore.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<h2 class=\"wp-block-heading\"><strong>How Blockchain Technology Works?<\/strong><\/h2>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>Blockchain acts as a digital concept to store data. The main characteristic of blockchain technology is that data is recorded in blocks. These encrypted blocks are connected in a chronological series and shared among the participants of the blockchain and secured through complex math problems. Hence, people also call it Distributed Ledger Technology (DLT).<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>There are three main aspects to this process \u2013 blocks, nodes, and miners.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<h3 class=\"wp-block-heading\">1. <strong>Blocks <\/strong><\/h3>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>Blocks are similar to the pages of a ledger. Each block holds the information of various transactions added. The data once encrypted into the block is immutable. A series of these blocks, connected through hashes in a chronological form, make up a blockchain.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<figure><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/hh-certificates.sgp1.digitaloceanspaces.com\/blog\/wp-content\/uploads\/2022\/11\/29070314\/shubham-dhage-JlijbOtSWuw-unsplash-1024x576.jpg\" alt=\"blocks\" width=\"454\" height=\"254\" \/><\/figure>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>The blocks consist of three unique features \u2013<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<ul class=\"wp-block-list\">\n<li>Data in the blocks \u2013 Users can store any data in the blocks and link the blocks through cryptography.<\/li>\n<li>Nonce \u2013 The full form of the word is \u201cnumber used only once\u201d. This is a set of unique numbers generated on the addition of a newly encrypted block. Miners work on decoding these nonces to match up to the previous hash. This process is extremely complex and strenuous and thus, the miners receive rewards for solving each nonce and creating the block.<\/li>\n<li>Hash \u2013 Hash is a value generated from a string of text added in the block using mathematical formulae. The hash generated for a block gets permanently attached to the nonce of the block. The value is always of a fixed length irrespective of the length of the block data. Hashes play an important role in connecting the blocks and forming the series of blockchains.<\/li>\n<\/ul>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<h3 class=\"wp-block-heading\">2. <strong>Nodes <\/strong><\/h3>\n<p>\n\n\n<p><\/p>\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Top 10 Blockchain Certification Courses in India | ReviewsReporter\" width=\"720\" height=\"405\" src=\"https:\/\/www.youtube.com\/embed\/s6FpNSpDqPY?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<\/p>\n<figure><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/hh-certificates.sgp1.digitaloceanspaces.com\/blog\/wp-content\/uploads\/2022\/11\/29070818\/laptop-which-there-is-world-people-drawn-1024x683.jpeg\" alt=\"network of nodes\" width=\"495\" height=\"330\" \/><\/figure>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>Nodes in blockchain refer to all the network stakeholders and their computer systems.

This transaction, before being encrypted on a block, is validated by the nodes. Once considered to be valid, the transaction is added to a block. The block is generated by the miners who use various formulae and generate a unique nonce and hash for the block.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<h3 class=\"wp-block-heading\">2. <strong>Linking blocks \u2013 <\/strong><\/h3>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<figure><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/hh-certificates.sgp1.digitaloceanspaces.com\/blog\/wp-content\/uploads\/2022\/11\/30105357\/3226083_43028-1024x745.jpg\" alt=\"linking blocks in blockchain technology\" width=\"466\" height=\"338\" \/><\/figure>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>This block is then added to the series of blockchains chronologically. To ensure the chronology is intact, the new block also has the hash of the previous block mentioned in the header along with its own unique nonce, hash, and transaction details. Since all blocks depend on information from the prior blocks, a strong chain of dependency is created. Hence, it is called the blockchain. This way, the authenticity of the data is protected. If any change is made in any of the blocks, the hash of the blocks placed after that block also changes.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<h3 class=\"wp-block-heading\">3. <strong>Sharing of Blockchain \u2013<\/strong><\/h3>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<figure><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/hh-certificates.sgp1.digitaloceanspaces.com\/blog\/wp-content\/uploads\/2022\/11\/29074244\/earth-gbea4cda7c_1920-1024x683.jpg\" alt=\"network of nodes\" width=\"491\" height=\"327\" \/><\/figure>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>The changes can be verified by the other stakeholders.

There is no necessity for any kind of permission to be a part of the network.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>Since it is so transparent, this kind of blockchain is suitable for usage in voting by the government, and fundraising activities.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<h3 class=\"wp-block-heading\">2. <strong>Private Blockchain<\/strong><\/h3>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>This blockchain network is smaller when compared to the public network. Usually smaller organizations run this kind of network. The information is available for all stakeholders of the organization but not everyone. Techies also call this network Permissioned blockchains and business blockchains.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>The closed network is suitable in cases of supply chain management, and asset ownership records.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<h3 class=\"wp-block-heading\">3. <strong>Hybrid Blockchain<\/strong><\/h3>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>Organizations that wish to implement both, public and private blockchains into their system use this kind of blockchain. The flexibility provides them with a choice to decide what information they wish to keep private within the organization and which to provide access to the public. The use of smart contracts can validate access to the public.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>Real estate companies, retail stores, and highly regulated markets like banking use hybrid blockchain in the best way.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<h3 class=\"wp-block-heading\">4. <strong>Consortium Blockchain<\/strong><\/h3>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>Also known as the Federated blockchain, the consortium blockchain is similar to the hybrid blockchain. However, predetermined nodes control who initiates, and validates all transactions in blockchains. Though the other members are also capable of initiating and receiving transactions, only validator nodes provide validation.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>The best way to use the consortium blockchain is for payments and banking as various banks can form a network and assign power to validator nodes.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<h2 class=\"wp-block-heading\"><strong>How <\/strong>to use <strong>Blockchain Technolo<\/strong>gy<strong>?<\/strong><\/h2>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>The usage of blockchain in cryptocurrency transactions is not unknown to anyone in today\u2019s world. The omission of any third party like banks gives the users enough flexibility and transparency in the process. This makes real-time transactions possible even across countries without any hassle or huge transaction fees.<\/p>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>However, there are many other ways to use blockchain technology.

Hence, the decentralization of data makes it trustworthy.<\/li>\n<li>Smart contracts make the process of transactions even simpler and more automated.<\/li>\n<li>Storage of documentation in blockchains can completely eliminate the use of paper documentation while improving security and privacy.<\/li>\n<\/ul>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<h3 class=\"wp-block-heading\"><strong>Disadvantages of Blockchain Technology<\/strong><\/h3>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<ul class=\"wp-block-list\">\n<li>The application slows down when there are more users of the network.<\/li>\n<li>There is excessive usage of energy, especially by miners. Miners solve various mathematical problems for the creation of blocks and in most cases, this consumes very high power.<\/li>\n<li>Though the immutable nature of blockchain is very useful, it is very difficult to make corrections in the data in case of mistakes.<\/li>\n<li>The cost of implementation and working of the technology is very high.<\/li>\n<li>The users get private keys to access the network. But in case of loss of this key, recovery is almost close to impossible and can cause a big problem, especially for cryptographic value holders.<\/li>\n<\/ul>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<h2 class=\"wp-block-heading\"><strong>Why learn about Blockchain Technology?<\/strong><\/h2>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<figure><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/hh-certificates.sgp1.digitaloceanspaces.com\/blog\/wp-content\/uploads\/2022\/11\/29143422\/OKTOBERFEST-5-1024x768.jpeg\" alt=\"learn blockchain technology\" width=\"478\" height=\"358\" \/><\/figure>\n<p>\n\n\n<p><\/p>\n\n\n<\/p>\n<p>Because it is the future!

As a coordinator, senior language instructor, center head and a content writer the basic requirement at the DNA level was the same \u2013 effective communication. He discovered early in life that quality of communication makes the difference between great results and mediocre outcomes. And thus, he developed his first forte: focus on the listener and tailor the message accordingly. As he progressed in his career, he realized that the most compelling stories communicate through multi-sensory messaging - a powerful combination of visual, verbal, and intuitive content."},{"@type":"Person","@id":"https:\/\/www.henryharvin.com\/blog\/#\/schema\/person\/9e93b4bd9ba4662a3515e8493abbcb85","name":"Varsha Alva","image":{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/hh-certificates.sgp1.digitaloceanspaces.com\/blog\/wp-content\/uploads\/2022\/11\/21151047\/Dp-1-150x150.jpg","url":"https:\/\/hh-certificates.sgp1.digitaloceanspaces.com\/blog\/wp-content\/uploads\/2022\/11\/21151047\/Dp-1-150x150.jpg","contentUrl":"https:\/\/hh-certificates.sgp1.digitaloceanspaces.com\/blog\/wp-content\/uploads\/2022\/11\/21151047\/Dp-1-150x150.jpg","caption":"Varsha Alva"},"description":"With over four years of experience in varied roles, I aspire to be the best in whatever I do. As a child, I heard people say that it is better to be the \"Master-of-one\" than a \"Jack-of-all\". Yet, jack-of-all was what intrigued me. So with the skills and knowledge that I have gained in life as a hospitality professional, in business development, and as a pastry chef, I am now on my journey to be one of the best content writers.
