Basic Concepts in Cryptocurrencies (Block Chain, Cryptocurrencies, Wallets, Addresses, Transactions)

Here are the basic concepts you need to know to understand cryptocurrencies better.


A simple definition of cryptocurrencies is restricted entries in a database which cannot be altered without satisfying certain conditions. A network of peers constitutes a cryptocurrency such as Bitcoin. Each peer has a record of the comprehensive records of every transaction and therefore the balance of every account. Mainly, cryptocurrencies are records related to token in decentralized consensus database. Unbreakable cryptography protects the term cryptocurrency established due to the consensus-keeping procedure. Cryptocurrencies are developed on the basis of cryptography. They are not protected by individuals or trust but by mathematical algorithms. A public key cryptography structure protects cryptocurrency reserves. Simply the holder of the private key can send cryptocurrency. Highly reliable cryptography and the durability of large numbers makes it almost impossible to break into this arrangement.


The blockchain is definitely an ingenious creation. By letting digital data to be circulated while making sure that it does not get duplicated, blockchain technology shaped the infrastructure of a new kind of internet. Blockchain was originally formulated for the digital currency, widely recognized as Bitcoin. In order to have a basic understanding of blockchain, you need to imagine a database, which is reproduced thousands of times throughout a network of computers. Now picture this network is intended to update this database on a regular basis. This will provide you with the basic understanding of the blockchain. Data stored on a blockchain exists as a shared and continuously reconciled database. This is the method of utilizing the system, which has understandable advantages. The blockchain database is not stored at a single location, which means that the record it stores are actually public and conveniently verifiable. A central version of this data does not exist making it completely secure from a hacker or possibility of corruption. Held by millions of computer at the same time, anyone on the internet can access the data on a blockchain.


A software, which holds your private and public keys for your cryptocurrency is identified as a cryptocurrency wallet. It communicates with a number of blockchains to empower its owner to initiate a transaction for his/her cryptocurrency as well as to keep track of their balance. In case you wish to deal with any cryptocurrency such as Bitcoin, it is a prerequisite to have a cryptocurrency wallet. Millions of individuals make use of cryptocurrency wallets. However, there is substantial misapprehension related to the way a wallet works. In contradiction with customary wallets in your back pockets, digital wallets do not store cryptocurrency. In fact, cryptocurrencies do not get stored in any particular location or exist anywhere in any physical form. All that exists are records of transactions stored on the blockchain.

There are different kinds of wallets, which deliver different techniques to access and save your cryptocurrency reserves. Cryptocurrency wallets can be further divided into three different types namely paper, hardware or software. Paper wallets are convenient to use and deliver an exceedingly high standard of security. A paper wallet is just referred to a physical copy of your private and public keys in a printed form. Hardware wallets save the private key of a user on a storage device similar to a USB. While hardware wallets allow you to make a transaction through an online system, they are saved offline. This ensures delivery of improved security standards. Hardware wallets can be suitable for a number of web interfaces and can support different cryptocurrencies.

Software wallets are different from hardware wallets, and they come in three different subtypes, which are an online wallet, desktop wallet, and mobile wallet. Online wallets are based on the cloud technology and can be accessed from any computer and any location. Although they are accessible in a far secure manner, online wallets save your private keys on an online system, which is administered by a third party. This makes an online wallet more prone to the risk of being hacked. Unlike online wallet, a desktop wallet can be downloaded and installed on a laptop or a PC and can be accessed from that particular computer only. While this makes a desktop wallet secure in one way, on the other hand, if the computer is hacked or get infected by a virus, then there will be a high risk that you may lose all your cryptocurrency reserves. Mobile wallets run on an application on your smartphone and are handy for the reason that they can be used everywhere including retail stores. These wallets are typically much smaller in size and simpler as compared to desktop wallets because a smartphone can offer a limited space for a mobile wallet.


A cryptocurrency address is fundamentally the similar thing as your residential address. It is the location from which you can send, receive and store your cryptocurrency. These addresses are usually comprised of an extended sequence of alphanumeric characters. A wallet address is the public portion of the twofold encoded keys essential for a cryptocurrency owner to receive or confirm a transaction. The address itself does not matter, nor does its format. The only thing matters are that the address accomplishes its purpose, which is to allow payments to an individual who has distinctive evidence, usually, a private key, to exclusively access the funds. Simply put an address a protected identifier.


A transmission of reserves amid two cryptocurrency wallets is identified as a transaction. This transaction gets submitted to a public ledger and waits for validation. When a transaction is made, wallets utilize an encoded electronic signature. This is an encoded part of data also identified as a cryptographic signature, to deliver calculated evidence that the transaction is generated from the holder of the wallet. The validation procedure takes a bit of time, usually a few minutes while “miners” mine. Mining authorizes the transactions and adds them to the public ledger.
