ARK is a cryptocurrency- and blockchain- based development platform allowing anyone to create their own fully customizable and interoperable blockchain. Reducing the industries need for Smart Contracts by using custom transactions, logic and multiple programming languages. ARK was founded in mid 2016, running a Toekn Exchange Campain(TEC) later that year which raised $800K in bitcoin and other exchanged cryptos. Sound financial planning has allowed the team to become a well-funded entity since its inception. On March 21, 2017, the ARK Public Network went live, hosting the native ARK crypto asset. The ARK business entity formed shortly after, called ARK ECOSYSTEM SCIC. The business entity is commonly referred to as 'ARK.io' which is part of the teams branding as well as the teams website.

The ARK Ecosystem consists of an open-source blockchain technology stack authored in TypeScript programming language. ARK’s public network acts as a live implementation of ARK technology, node operators acting as delegates on the network, standalone blockchains running on ARK technology with independent node operators, business entities that develop products powered by ARK as well as assist in maintaining the code base, an enterprise division driving adoption as well as a community of users, developers and service providers.

The ARK Public Network supports special transaction types such as multi-payment, multisignature, many various registration transactions, and IPFS hash transactions. ARK’s Launcher product, allows fully customizable interoperable blockchain creation using a graphical user interface.

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.

REQ is listed on Coinbase, Binance, crypto.com, KuCoin and many other exchanges.

The REQ token powers the Request Network open-source protocol via a few mechanisms: anti-spam; governance; staking; discounts; independency.

The Request (REQ) utility token, launched in 2017, ensures the performance and stability of the Request Network. The Request Network itself is an Ethereum-based decentralized payment system where anyone can request a payment and receive money through secure means. It removes the requirement for third parties in order to provide a cheaper, more secure payment solution that works with all global currencies.

The original whitepaper is available here.

When a user creates a request for payment, they define to which address the payment needs to be allocated and what the amount is. The user can also define the terms and conditions of the payment, upgrading a simple request into an invoice. Once this is completed, the user can share their request to be paid by their counterparty.

Every step is documented and stored on the Request Network, allowing everyone involved to easily keep track of all the invoices and payments for accounting purposes.

Request is also integrated with legislation across the world to remain compliant with the trade laws of each individual country.

Civic is a blockchain-based identity management solution that gives individuals and businesses the tools they need to control and protect personal identity information.

The platform is designed to change the way we think about identity verification by giving users more control over their personal data, while allowing them to access a wide range of services without needing to fork over excessive amounts of personal information.

Civic's identity verification solution uses distributed ledger technology to authorize identity usage in real time, and is used to sparingly share information with Civic partners after authorization by the user.

Unlike some other identity management services, Civic users store all their sensitive data on their mobile device. Users are able to authorize the sharing of specific personal data by providing a biometric signature through the Civic app.

The Civic ecosystem is enabled by a unique utility token known as the Civic token (CVC), which is used for the settlement of identity-related transactions between Civic participants — such as between a customer and service provider.

Users can earn CVC tokens for completing a variety of tasks, such as signing up for a service through the platform or introducing new users, while validators can earn CVCs for validating documents for service providers.

Civic was launched in 2018, following a sell-out initial coin offering (ICO) the year prior.

JUST is a popular new decentralized finance (DeFi) ecosystem built for the TRON blockchain. It is an entire suite of products that are mostly centered around a decentralized stablecoin lending platform known as JustStable.

The platform launched in August 2020 following an initial exchange offering (IEO) on the Poloniex LaunchBase platform earlier that same year, but the native governance token of the platform (JST) has been circulating since May 2020.

It is a two-token ecosystem built around the USDJ and JUST (JST) tokens. USDJ is a multi-collateral stablecoin that has its value pegged to the value of the US dollar (USD), whereas JST has a variety of functions on the platform — paying interest, helping maintain the platform and participating in its governance, helping to set parameters like interest rates (stability fees) and the minimum collateralization ratio.

To obtain USDJ on JUST, traders need to deposit collateral in the form of supported collateral tokens — including TRON (TRX), which are exchanged to PTRX tokens and locked as collateral forming a collateralized debt position (CDP). Depending on the amount of collateral deposited, users can then mint and withdraw USDJ, which must later be repaid to retrieve the initial collateral.

The platform is designed to provide a fair and borderless hub of DeFi products, that any TRON user can access.

Hive (HIVE) is a blockchain running on a delegated proof-of-stake (DPoS) consensus mechanism. It launched in March 2020 as a hard fork of the centralized Steem blockchain and as a gateway from Web 2.0 to Web 3.0. The blockchain claims to offer “lightning-fast processing times and fee-less transactions.” Examples of use cases include social media with monetized rewards for content creators, interactive blockchain games, identity management, micro-loans and more. The platform powers decentralized applications (dApps) like Splinterlands, PeakD and HiveBlog.

Hive is a social network of apps and services, where users discover the capacity of blockchain technology, connect to the platform and securely share content through equitable redistribution of value. Thus, the users are the proprietors of the network, and sponsors can contact communities and artists directly without intermediaries.

Hive is an open source blockchain that focuses on scaling through layer-2 sidechains, while still benefiting from a common layer-1 blockchain backbone to ensure distributed data integrity. The Hive ecosystem runs on two cryptocurrencies — the native governance token, HIVE and the USD-pegged HBD stablecoin.
