24 Jun Cryptocurrency Algorithms: Different coins and popular algorithms in the market.

Cryptocurrencies:

A cryptocurrency, in general terms, is virtual or digital money in the form of tokens or “coins.” Though some cryptocurrencies have entered the real world through credit cards or other schemes, the vast majority remain completely intangible.

The term “crypto” refers to the complex encryption that enables the creation and processing of digital currency and their transactions across decentralized platforms. Along with this crucial “crypto” aspect is a shared commitment to decentralization; cryptocurrencies are often developed as code by teams that include methods for issuance and other restrictions.

Coins and altcoins:

Any cryptocurrency with its own blockchain is referred to as a coin. Because Bitcoin functions on its own infrastructure, it is categorized as a “currency.” The Ethereum blockchain, like Bitcoin, governs Ether.

The term “altcoin” refers to any coin other than Bitcoin. Many altcoins function similarly to Bitcoin. Others, like Dogecoin, are quite different. Doge, for example, offers an endless amount of currencies, but Bitcoin is limited to 21 million units.

Major Cryptocurrency Kinds and How They Work:

Bitcoin (BTC):

Bitcoin was the world’s first cryptocurrency, going back to a white paper released in 2008, and it is still the most well-known sort of crypto. It runs on its own blockchain, with an army of decentralized miners verifying transactions (and creating new Bitcoins up to a certain limit). Bitcoin had the greatest market capitalization in January 2022, at US$896 billion.

Bitcoin, being the coin that heralded the cryptocurrency age, is still the coin that most people think of when discussing digital currency. The currency’s mysterious creator, purportedly Satoshi Nakamoto, unveiled it in 2009, and it’s been on a roller-coaster ride ever since. However, it wasn’t until 2017 that bitcoin entered the public mind.

Ethereum (ETH):

Ethereum (ETH), the first Bitcoin alternative on the list, is a decentralized software platform that allows smart contracts and decentralized apps (dApps) to be written and deployed without downtime, fraud, control or intervention from a third party. The purpose of Ethereum is to establish a decentralized suite of financial goods that anybody in the world, regardless of nationality, race or creed, may freely access.

Ethereum apps are powered by ether, the platform’s exclusive cryptographic token. Ether (ETH) is a vehicle for moving throughout the Ethereum network and is mostly sought by developers trying to create and operate apps within Ethereum, as well as investors wishing to acquire other digital currencies using ether.

Ether (ETH):

The cryptocurrency Ether is based on the Ethereum blockchain. Ether, like Bitcoin, works on its own blockchain; but unlike Bitcoin, Ether is uncapped, which means that a limitless amount of currencies may theoretically be minted. Smart contracts, which are programmes that run on the Ethereum blockchain and are executed automatically when specific criteria are satisfied, are also supported by Ethereum.

Litecoin is a cryptocurrency (LTC):

Litecoin (LTC), which initially appeared in 2011, was one of the first cryptocurrencies to follow in the footsteps of Bitcoin and has been termed the “silver to Bitcoin’s gold.”

Litecoin is based on an open-source global payment network that is decentralized, and it employs scrypt as a PoW that can be decoded by consumer-grade central processing units (CPUs). In many ways, Litecoin is comparable to Bitcoin, except that it has a greater block generation rate and, as a result, a faster transaction confirmation time.

Tether (USDT):

Tether is a stablecoin that is connected to an external asset to provide a less fluctuating pricing. In this situation, each coin is backed by an equivalent quantity of US dollars, preventing it from experiencing the same market volatility as other cryptocurrencies.

The price of Tether is set at $1 per coin. This is due to the fact that it is a stablecoin. Stablecoins are coins that are linked to the value of a single asset, in Tether’s instance, the US dollar. Dollar. Tether is frequently used as a bridge currency when traders transfer from one cryptocurrency to another. They utilize Tether instead of returning to dollars.

Polkadot (DOT):

Polkadot is a digital currency that will be introduced in May 2020 and connects blockchain technology from various cryptocurrencies. Polkadot’s co-founder is an Ethereum co-founder, and some industry analysts believe Polkadot is seeking to dethrone Ethereum.

Polkadot (DOT) is a unique PoS currency that aspires to be compatible with different blockchains. Its protocol combines permissioned and permissionless blockchains as well as oracles, enabling systems to interact under a single umbrella. The key component of Polkadot is its relay chain, which facilitates network interoperability. For some use cases, parachains or secondary blockchains with their own native currency, are also supported.

Cryptographic algorithms:

Cryptographic algorithms are sets of procedures or rules that are used in a cryptographic system to encrypt and decode communications. They are ways that protect data by prohibiting unauthorized users from accessing it. These algorithms, among other things, can be utilized to ensure secure and validated financial transactions.

The use of encryption in most cryptography techniques allows two parties to communicate while prohibiting unauthorized third parties from comprehending those conversations. Encryption is the process of converting human-readable plaintext into unreadable ciphertext. The encrypted data is subsequently decoded to make it comprehensible to the intended recipient. Algorithms are used in both encryption and decryption.

Common Encryption Algorithms:

IDEA:

The International Data Encryption Algorithm (IDEA) uses a 128-bit key and a rounding method to encrypt data. Pretty Good Privacy, an email privacy solution, uses IDEA as a block cipher (PGP). Data is sent in 64-bit chunks.

The 64 bits are divided into four 16-bit segments. Each round, individual sub-blocks are updated. IDEA uses substitution and transposition to scramble data.

AES:

The Advanced Encryption Standard (AES) is the algorithm that the US Government and many other organizations rely on. Although 128-bit keys are incredibly efficient, AES also utilizes 192 and 256-bit keys for heavy-duty encryption.

Except for brute force, which attempts to decrypt messages using all possible combinations in the 128, 192, or 256-bit encryption, AES is widely believed immune to all assaults.

Twofish:

Twofish was a finalist in the National Institute of Standards and Technology Advanced Encryption Standard competition, but it was defeated by Rijndael. The Twofish method has key sizes of 128, 196, and 256 bits and has a complicated key structure that is tough to crack.

Twofish is regarded by security experts as one of the quickest encryption algorithms and a great choice for hardware and software. Furthermore, anyone may utilize the Twofish cipher.

RSA Security:

RSA is a public-key encryption method that is widely used to encrypt data delivered over the internet. It is also one of the mechanisms used by PGP and GPG applications. RSA, unlike Triple DES, is an asymmetric method due to its usage of a pair of keys. You have a public key for encrypting the communication and a private key for decrypting it. RSA encryption produces a massive amount of gibberish that requires a significant amount of time and computing power to break.

Diffie-Hellman:

Diffie-Hellman is a public key exchange mechanism, however, it is also regarded as an algorithm by others. Diffie-Hellman is a popular method for sharing private keys over public networks. It’s also known as a key agreement protocol since it selects the private key of both parties, will use following a series of data exchanges. It has been used for decades in symmetric encryption methods to share private keys.

Conclusion:

Anyone working in IT these days is concerned about security. Gartner predicts that spending on information security and risk management would reach $172 billion in 2022, up from $155 billion in 2021. While there are other technologies available to purchase to safeguard your data, encryption is one component of security technology that every computer user should be familiar with.
