When someone mentions cryptocurrency, they're talking about a digital currency that uses cryptography to secure transactions and control the creation of additional units. The concept was first introduced by an anonymous person or group known as Satoshi Nakamoto in 2008.
Cryptocurrencies are usually built upon decentralized networks (i.e., blockchain technology), but cryptocurrencies can also be centralized or distributed in nature.
Cryptography is simply the process of using mathematical algorithms to encrypt information so that only those who possess the decryption key can read it. So when we talk about cryptocurrencies and blockchain technology, we are talking about things that are encrypted and need specific keys to understand what's happening within them.
Blockchain is a distributed ledger. It’s a digital record of transactions, but it’s not just that—it’s also a shared database and an app for uploading data to the internet.
Blockchain is not just the technology behind cryptocurrencies such as bitcoin or ether. Blockchain represents much more than just one type of digital currency. It's a disruptive force in many industries where trust is essential to everyday business operations.
Contracts and Smart Contracts
A contract is an agreement between two or more parties to do or not do a particular thing. A smart contract is an agreement that uses code to automate the performance of the contract and make sure it's fulfilled
Smart contracts are part of the blockchain, which means they are stored on a decentralized ledger (the blockchain) and cannot be altered once written into it. This allows for transparency, immutability, and trust in transactions without requiring legal involvement because everyone can see what was agreed upon in real-time.
Wallets & Cryptocurrency Wallets
A cryptocurrency wallet is a safe digital wallet that may be used to store, transmit, and receive digital currencies such as Bitcoin. Most currencies have an official wallet or a few third-party wallets that are officially endorsed.
A cryptocurrency wallet is required to utilize any cryptocurrency. A cryptocurrency wallet is a software that runs on your computer or mobile device that allows you to transmit, receive, and store digital currencies such as Bitcoin and Ethereum.
Tokens are the ones that are built on a blockchain. They can be used to represent a digital asset, digital information, digital file, or physical object.
Distributed Ledger Technology (DLT) & Hash Functions
Distributed Ledger Technology (DLT) is also known as blockchain technology. It is a decentralized system that allows for the verification of transactions without the involvement of any third party.
Essentially, it’s a database spread across multiple locations. The information stored on this shared ledger cannot be altered or deleted by any single entity. Instead, the data is maintained by the consensus of all participants in the network.
The term 'miner' refers to the people who validate transactions and then add them to the public ledger. A miner can also be defined as a computer that is running the mining software.
The process of validating transactions and adding them to the public ledger is known as "mining". Mining requires expensive hardware, electricity, and time; therefore, miners are rewarded for their contribution by receiving a small fee for every transaction that they validate for others.
In addition to this fee, miners receive newly created bitcoins (BTC) as well as transaction fees paid by users sending funds over the network.
Nodes, Decentralized & Centralized Blockchain Network
Nodes are computers connected to the network. A large number of nodes on a blockchain network makes it more secure and reliable.
The Bitcoin network is decentralized. It means that no single entity controls it, but there are some central points where most of the mining happens.
The Ethereum network is also decentralized and anyone can run a node on their computer or server. However, most people just connect to a public node because it’s easy and doesn't require any maintenance or configuration changes if your internet connection goes down for some reason (or if you move).
Proof of Work and Proof of Stake
Proof of Work and Proof of Stake are the two most important terms in the cryptocurrency industry. You must have heard them at least once or twice before.
● Proof of Work was first introduced by Adam Back in 1997. It requires miners to find a number called nonce which is smaller than a given threshold value and hash it with the SHA-256 algorithm to produce a valid block hash.
● Proof of Stake, however, differs from its predecessor as it doesn’t require any work (mining) to verify transactions on a blockchain network. This process is called “minting” and is more correctly referred to as "forging." In this case, the validator(s) are required to show ownership over some amount of cryptocurrency for them to create new blocks on the network.
Mining pools are groups of miners that combine their computing power to increase the chances of mining blocks. This is done because it is significantly more difficult for an individual miner to generate a block on his own. The reward for doing this is split among the pool members.
The more people join the mining pool, the greater your chance of creating blocks. This is more money kazan(you can also join pools with different risk levels).
As you may have guessed by now, this basic definition doesn't do justice to all the complexities involved when talking about mining pools.
Which are the Critical Ones?
There are numerous terms associated with cryptocurrencies. These These help you to converse with ease while taking any trades in the cryptocurrency markets . Apart from the above ones mentioned, you can do your own research to know more about the ones relevant to your need.
If you want to deal in cryptocurrencies, then it is critical to know the terminologies of the industry. If you are planning to invest in cryptocurrencies, then you need to understand what a token is? Tokens are digital assets that can be used as a medium of exchange or an investment instrument.
Ethereum, Waves etc. It has been created using various blockchain technology platforms such as These tokens represent a stake in the platform and can also provide voting rights over its use and development.
