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.

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.

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.

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.

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.

Nimiq is designed to make cryptocurrencies easy to use for everyone without compromising decentralization. Nimiq is the only blockchain where users always participate directly by default. In comparison to the likes of Bitcoin and Ethereum where the default is to use a third-party node to connect to the network. Learn more: https://youtu.be/dA40oyDVtqs

Team Nimiq invented Nimiq OASIS, the DeFi crypto-fiat bridge! Atomic swaps between crypto like NIM and BTC (ETH coming soon) and fiat currencies like EUR (USD next) with no personal information are now possible. Earned swap fees are converted to NIM and held to create scarcity. See how it works: https://youtu.be/Spp_Be4dHaM

Nimiq created Albatross, a new, super fast Proof-of-Stake consensus algorithm that will launch with Nimiq 2.0, the next version of the Nimiq Blockchain. We expect ~1000 TPS and finality in one second, pushing Nimiq 2.0 to the theoretical limits of single chain blockchain protocols. Energy consumption will also be reduced to less than 1% (compared to current Nimiq POW) with this upgrade. Try out the demo: https://www.nimiq.com/albatross/

Nimiq’s “super-halving” coming soon! The transition to Nimiq 2.0 will reduce the emission rate from currently ~3000 NIM to only ~525 NIM per minute. Calculate your rewards using the Staking Calculator: https://www.nimiq.com/staking-calculator/

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.

Library Credit (LBRY) is a platform that seeks to simplify the way digital content is distributed and accessed by both consumers and producers.

Library Credit uses a decentralized model to be fair, free, and open to all the involved parties.

More specifically, the platform functions as a distributed network built on top of a protocol that makes it easy for publishers to charge a fee to content consumers without censorship or the need for a middleman.

The project was launched towards the end of 2018 and is now serving an active community.

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.

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.

Ethereum Classic (ETC) is the original Ethereum (ETH) blockchain that launched in July 2015. Its main function is as a smart contract network, with the ability to host and support decentralized applications (DApps). Its native token is ETC.

Since its launch, Ethereum Classic has sought to differentiate itself from Ethereum, with the two networks’ technical roadmap diverging further and further from each other with time.

Ethereum Classic first set out to preserve the integrity of the existing Ethereum blockchain after a major hacking event led to the theft of 3.6 million ETH.
