Nxt (NXT) uses the blockchain to create an entire ecosystem of decentralized features, all of which require the Nxt currency. Instead of modifying the original Bitcoin source code, as many altcoins have done, Nxt developers wrote their own code in Java from scratch. While Nxt is a public blockchain, licenses for private blockchains based on its software are also available for purchase. The developers refer to Nxt as Blockchain 2.0, providing numerous applications beyond simply keeping a public ledger of transactions.

BitShares Blockchain is a decentralized “Blockchain as Organization” (BaO); an industrial-grade decentralized open source platform built to run high-performance financial technology operations. It represents the first decentralized autonomous decentralized community that enables its core utility token (BTS) holders to decide the Blockchain future direction in order to develop and maintain a wide range of decentralized financial technology products, features and functions. BitShares Blockchain is a Blockchain that permanently records financial technology operations between different Blockchain accounts and facilitates a wide range of access controls across BitShares Blockchain user financial means.

BitShares Blockchain is a technology that supports the digital generation entrepreneurs, investors, and developers with a common interest in building and participating in free market solutions by leveraging the power of globally decentralized consensus and decision making. Consensus technology has the power to do for economics what the internet did for information. It can harness the combined power of all humanity to coordinate the discovery and aggregation of real-time knowledge, previously unobtainable. This knowledge can be used to more effectively coordinate the allocation of resources toward their most productive and valuable use.

BitShares looks to extend the innovation of the Blockchain to all industries that rely upon the internet to provide their services. Whether its banking, stock exchanges, lotteries, voting, music, auctions or many others, a digital public ledger allows for the creation of distributed autonomous companies (or BaO) that provide better quality services at a fraction of the cost incurred by their more traditional, centralized counterparts. The advent of (BaO) ushers in a new paradigm in organizational structure in which companies can run without any human management and under the control of an incorruptible set of business rules. These rules are encoded in publicly auditable open source software distributed across the computers of the companies’ shareholders, who effortlessly secure the company from arbitrary control. BitShares does for business what bitcoin did for money by utilizing distributed consensus technology to create companies that are inherently global, transparent, trustworthy, efficient and most importantly profitable.

BitShares has went through many changes and has done its best to stay on top of Blockchain technology. BitShares is using Consensus as the mechanism by which organized people decide upon unitary rational action. While not considered technology in the traditional since, consensus “technology” is the basis of democratic governance and the coordination of free market activity first coined by Adam Smith as the “Invisible Hand.” The process of consensus decision-making allows for all participants to consent upon a resolution of action even if not the favored course of action for each individual participant. Bitcoin was the first system to integrate a fully decentralized consensus method with the modern technology of the internet and peer-to-peer networks in order to more efficiently facilitate the transfer of value through electronic communication. The proof-of-work structure that secures and maintains the Bitcoin network is one manner of organizing individuals who do not necessarily trust one another to act in the best interest of all participants of the network. The BitShares ecosystem employs Delegated Proof of Stake in order to find efficient solutions to distributed consensus decision making.

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.

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 a "network of decentralized markets and communities," district0x is a platform that allows users to easily launch their own decentralized platforms which are governed by a decentralized autonomous organization (DAO) structure.

Each of these platforms is termed a “district” and can be launched free of charge on the district0x. The ecosystem is powered by the custom d0xINFRA framework, which provides a set of basic smart contracts and libraries users can use when building out their districts — enabling a wide array of potential use-cases.

The native token of the district0x ecosystem is DNT — an ERC-20 utility token that is mostly used for community governance.

The platform uses a combination of three main technologies: Ethereum, Aragon and the InterPlanetary File Transfer Protocol (IPFS).

The Ethereum blockchain is used for hosting districts, whereas Aragon is used as the governance layer for the district0x network, allowing DNT stakers to benefit from governance rights and help shape the development and operation of their chosen districts. Lastly, IPFS is used for serving the district0x website source code and for user uploads within districts.

Kin is a decentralized cryptocurrency that was created in 2017 by Kik Inc.

Kin was initially launched on the Ethereum blockchain. In 2020, Kin migrated to the Solana blockchain in order to achieve lower transaction fees and greater scalability.

Notably, Kin has zero inflation. The Kin supply is fully distributed and no additional Kin tokens will enter circulation.

In 2020, Kik Inc agreed to a mutual settlement with the United States SEC in which Kin was not required to be registered as a security, making it one of the few cryptocurrencies with such regulatory clarity.

Hifi (formerly Mainframe) is a Lending Protocol that allows anyone to borrow against their crypto. Hifi uses a bond-like instrument, representing an on-chain obligation that settles on a specific future date. Buying and selling the tokenized debt enables fixed-rate, fixed term lending and borrowing — something much needed in decentralized finance today. It is anticipated that a ticker symbol change will occur alongside future iterations on the Hifi Lending Protocol.

Mainframe Token (MFT) is the native utility token that is used for:

Governance votes

Staking to ensure the safety of the protocol

Rewarding contributors to the ecosystem

What can you do with the Hifi Lending Protocol:

Borrow:  Lock collateral in a vault to mint fixed-rate, fixed-term debt tokens.  These debt tokens can be swapped for instant liquidity allowing users to leverage long, yield farm, or pursue other strategic trades without selling their collateral tokens.

Lend:  Buy fixed-rate, fixed-term debt tokens for a discount.  When the term expires they can be redeemed for face value, earning lenders a predictable return on their investment.

Provide Liquidity:  Earn trading fees by providing liquidity between debt tokens and stablecoins on an Automated Market Maker (AMM).

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.
