A node is a device on a blockchain network, that is in the crux the underpinning of the technology, allowing it to function and survive.  Nodes are disseminated across a widespread network and carry out a variety of tasks. In this blog we will try to understand what blockchain nodes are. A node can be any active electronic device, including a computer, phone or even a printer, as long as it is connected to the internet and as such has an IP address. The role of a node is to support the network by maintaining a copy of a blockchain and, in some cases, to process transactions. Nodes are often arranged in the structure of trees, known as binary trees. Each  cryptocurrency   has its own nodes, maintaining the transaction records of that particular token.  Nodes are the individual parts of the larger data structure that is a blockchain. As the owners of nodes willingly contribute their computing resources to store and validate transact ions, they have th...

Cryptocurrency mining is one of the most regularly used approaches of validating transactions that have been executed over a blockchain network. Not only does blockchain work to protect transaction data through encryption, as well as store this data in a decentralized manner (i.e., on hard drives and servers all over the world) so as to keep a single entity from gaining control of a network, but also the primary goal is to ensure that the same crypto token isn't spent twice. In effect, "mining" is one means of making sure that cryptocurrency transactions are accurate and true, such that they can never be compromised in the future. Cryptocurrency mining itself refers to a type of validation model known as "proof-of-work" (PoW). There are two common validation types, and we'll look at the other, known as proof-of-stake, in a moment. In the PoW model -- which bitcoin , Ethereum, Bitcoin Cash, and Litecoin use, to name a few -- individuals, group...

Cryptojacking (also called malicious cryptomining) is an emerging online threat that hides on a computer or mobile device and uses the machine’s resources to “mine” forms of online money known as cryptocurrencies . It’s a burgeoning menace that can take over web browsers, as well as compromise all kinds of devices, from desktops and laptops, to smart phones and even network servers. Like most other malicious attacks on the computing public, the motive is profit, but unlike many threats, it’s designed to stay completely hidden from the user.  Cryptojacking is a scheme to use people’s devices (computers, smartphones, tablets, or even servers), without their consent or knowledge, to secretly mine cryptocurrency on the victim’s dime. Instead of building a dedicated cryptomining computer, hackers use cryptojacking to steal computing resources from their victims’ devices. When you add all these resources up, hackers are able to compete against sophisticated cryptomining o...
