Vertcoin (VTC) is an ASIC-resistant P2P Litecoin fork that uses PoW to reach consensus. Billed as the 'The People's Coin', the Vertcoin ascribes primacy to keeping its mining functions decentralized, and seeks to allow anyone with a personal computer to join the Vertcoin network.

Towards this end, Vertcoin has its very own 1-click miner, a program meant to make mining more accessible to the general public. In Jul 2014, Vertcoin released a wallet supporting Stealth Address transactions.

Peercoin, also known as PPC or Peer-to-Peer Coin, was created by Sunny King and his team and launched in August 2012. It is the first blockchain to implement Proof-of-Stake consensus.

The primary inspiration behind the creation of Peercoin was to address a number of perceived shortcomings of Bitcoin, including energy efficiency, security and sustainability, decentralization and long-term viability.

Essentially it was designed as an enhanced replacement for Bitcoin. As such, it was originally forked from Bitcoin and uses the same UTXO style blockchain. However, Peercoin's code was modified to introduce Proof-of-Stake as its primary consensus protocol. The next section explains how this makes for a better blockchain.

Given that Peercoin uses most of the same code, it can easily port new features from Bitcoin and utilize any of the supporting infrastructure, including tech advancements like Taproot or Lightning Network. Peercoin is the only Proof-of-Stake blockchain that uses modern Bitcoin code, making it the perfect drop-in replacement.

Peercoin also has a dedicated community, is actively developed, fairly distributed, has low barriers of participation, can do everything that Bitcoin does, minus the 13 TWh of energy usage, and it's not a scam.

Firo (FIRO), formerly known as Zcoin, is a cryptocurrency that focuses on being private digital cash. It created the Lelantus privacy protocol which allows users to burn their coins and redeem them later for brand new ones that do not have any transaction history.

Prior to Lelantus, it was also the first cryptocurrency to code and launch a practical implementation of the Zerocoin protocol which became one of the most prevalent privacy protocols in use, prior to it being replaced by Sigma and then Lelantus after cryptographic flaws were discovered in the Zerocoin protocol in 2019.

Bitcoin Gold was founded in 2017 to become a user-friendly alternative to Bitcoin. The BTG network aims to combine the security and sturdiness of the Bitcoin blockchain and its characteristics with the opportunity for experimentation and development.

BTG enhances and extends the crypto space with a blockchain closely compatible with Bitcoin but without using resources like Bitcoin hash power or vying for the "real Bitcoin" title. The company aims to present a coin with the implementation capabilities of Bitcoin, however, expanding on the opportunities for DeFi and DApp developers to use the coin.

Ravencoin is a digital peer-to-peer (P2P) network that aims to implement a use case specific blockchain, designed to efficiently handle one specific function: the transfer of assets from one party to another. Built on a fork of the Bitcoin code, Ravencoin was announced on Oct. 31, 2017 and released binaries for mining on Jan. 3, 2018 with what is called a fair launch: no premine, ICO or masternodes. It was named in reference to a TV show Game of Thrones.

Haven Protocol is similar to an offshore bank where users can create private tokens that represent stable and volatile assets, including commodities and fiat currencies (such as USD). The protocol is based on Monero, which focuses on secure, private and untraceable transactions.

As a result, most of the features of Monero extend to the Haven protocol, including the bulletproofs and other privacy tech. The base currency of Haven is the XHV, which is burnt to provide users with private, untraceable, synthetic assets and commodities called xAssets.

The network uses a “mint and burn” process to provide users with untraceable digital assets with standard market pricing and real asset-pegged value storage. Simply, users can burn Haven (XHV) for Haven Dollars (xUSD), which is a synthetic stablecoin.

Verge is a privacy-focused cryptocurrency and blockchain that seeks to offer a fast, efficient, decentralized payments network that improves upon the original Bitcoin (BTC) blockchain. It includes additional privacy features including integrating the anonymity network Tor into its wallet, called vergePay, and providing the option of sending transactions to stealth addresses.

The project describes itself as community-driven, relying on volunteers and priding itself on being open source.

Verge was first launched in October 2014 as DogeCoinDark, a fork of Peercoin (PPC). In February 2016, it was renamed Verge in order to rebrand for easier mass-market adoption and to distinguish itself from Dogecoin (DOGE), with which it has no direct connection. The project is now based on the Bitcoin source code.

DigiByte (DGB) is an open source blockchain and asset creation platform. Development began in October 2013 and the genesis block of its DGB token was mined in January 2014 as a fork of Bitcoin (BTC).

A longstanding public blockchain and cryptocurrency, DigiByte uses five different algorithms to improve security, and originally aimed to improve on the Bitcoin blockchain’s security, capacity and transaction speed.

DigiByte consists of three layers: a smart contract “App Store,” a public ledger and the core protocol featuring nodes communicating to relay transactions.

Siacoin (SC) is the native utility token of Sia, a blockchain-based distributed, decentralized cloud storage platform. Sia acts as a secure, trustless marketplace for cloud storage in which users can lease access to their unused storage space. Agreements and transactions are enforced with smart contracts, and Siacoin is the medium of exchange for paying for storage on the network. The main goal of the project is to become the "backbone storage layer of the internet."

Sia was originally announced in May 2014 before being revised and re-announced a year later in May 2015. It officially launched in June 2015.

NEM is a blockchain platform that was launched in March of 2015. It was one of the pioneers of the cryptocurrency industry, and sought to improve on the imperfections found on other chains at the time. It was one of the first non-turing complete chains to feature user-defined tokens (called mosaics), namespaces, multisignature accounts, and a P2P reputation system based on EigenTrust++. Its most notable contribution to the space is the proof-of-importance consensus mechanism, which sought to reward on-chain activity and deter the concentration of wealth commonly associated with proof-of-stake. Its client, NIS, is written in Java.

NEM has a global community. It sees the most utility as an alternative form of payment for businesses and vendors, and has a variety of social media apps built on top of it in Japan, such as nemgraph, a community-driven owned and operated alternative to Instagram.

In December 2021, NEM was hard forked by a pseudonymous team of cryptocurrency experts and enthusiasts alike. Titled Harlock, this hard fork signaled the community’s intent to take NEM from a shadow of its former self into the world’s leading payments platform for on-chain and off-chain media content.

Billed as "digital money for the modern world," nano is a lightweight cryptocurrency that is designed to facilitate secure, practically instant payments, without fees, and addresses some of the major limitations of both legacy financial infrastructure, and many modern cryptocurrencies.

Development of the project began in 2014 under the name RaiBlocks, and the coin (then termed XRB) launched the following year through a public faucet, which allowed users to claim small amounts of XRB after completing a captcha challenge. Anyone with access to a computer or phone could solve captchas, and be rewarded with RaiBlocks. The number of XRB people received per solved captcha varied over time

RaiBlocks (XRB) was rebranded to Nano in January 2018, with the new name chosen to better represent the speed and simplicity the project offers to users.

It is a peer-to-peer platform that uses a unique block-lattice data structure to allow users to easily transfer value to one another without relying on centralized intermediaries.

Unlike other platforms which typically use the combined proof-of-work of a massive mining network to achieve consensus, nano instead uses a system known as Open Representative Voting (ORV) — which sees account holders vote for their chosen representative, who then work to confirm blocks of transactions securely.

ORV makes Nano extremely energy efficient, positioning it as a more environmentally friendly alternative to proof-of-work (POW)-based cryptocurrencies.

In November, 2021, aiming to bring nano to the real world and to comply with the globally-recognized standards of the International Organisation for Standardisation (ISO) requirements, nano adopted a new ticker and a standard symbol: XNO and Ӿ.
