"Aidos Kuneen is an open source project that focuses on privacy, decentralization and scalability. Lets face it our financial privacy is in danger, banks and governments not only want to keep record of how we spend and store our money they are also prone to having this records leaked or using the information to enforce their power. This is where Aidos comes in: being secure, private and untraceable."
“Mainstream adoption of blockchain systems has been limited due to unsolved questions of scalability, privacy, and interoperability. In this paper, we will outline a proposed design for the Aion Network; a 3rd generation multi-tier blockchain system designed to address these challenges. Core to our hypothesis is the idea that many blockchains will be created to solve unique business challenges, within unique industries. As such, the Aion Network is designed to support custom blockchain architectures, while providing a trustless mechanism for cross-chain interoperability. At the root of this system is the world’s first dedicated public enterprise blockchain, Aion-1; a state of the art blockchain that introduces a new paradigm of security, and fair, representative crypto-economic incentives.”

Basic Attention Token (BAT)
"Digital advertising is broken. The marketplace for online advertising, once dominated by advertisers, publishers and users, has become overrun by middleman" ad exchanges, audience segmentation, complicated behavioral and cross-device user tracking, and opaque cross-party sharing through data management platforms. The solution is a decentralized, transparent digital ad exchange based on Blockchain. The first component is Brave, a fast, open source, privacy-focused browser that blocks third party ads and trackers, and builds in a ledger system that measures user attention to reward publishers accordingly. Brave will now introduce BAT (Basic Attention Token), a token for a decentralized ad exchange. It compensates the browser user for attention while protecting privacy."
Binance Coin (BNB)
"In our view, there are fundamentally two different types of exchanges: the ones that deal with fiat currency; and the ones that deal purely in crypto. It is the latter one that we will focus on. Even though they are small now, we strongly believe that pure crypto exchanges will be bigger, many times bigger, than fiat based exchanges in the near future. They will play an ever more important role in world finance and we call this new paradigm Binance; Binary Finance. With your help, Binance will build a world-class crypto exchange, powering the future of crypto finance."
Bitcoin Cash (BCH)
"Bitcoin Cash brings sound money to the world, fulfilling the original promise of Bitcoin as 'Peer-to-Peer Electronic Cash'. Merchants and users are empowered with low fees and reliable confirmations. The future shines brightly with unrestricted growth, global adoption, permissionless innovation, and decentralized development."
"A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work."
"BitShares 2.0 is an industrial-grade decentralized platform built for high-performance financial smart contracts. The decentralized exchange that allows for trading of arbitrary pairs without counterparty risk facilitates only one out of many available features.

Civic hopes this ecosystem can reduce the overall costs of IDV, remove inefficiencies, enhance security and privacy, greatly improve user experience and disrupt the current IDV supply chain."
"CloakCoin is one of the best systems available providing private, secure, decentralized and untraceable digital monetary transactions. It is also one of the most user friendly systems and will allow anybody with a computer or a smartphone to participate in today’s digital markets."
"Counterparty embeds data into regular Bitcoin transactions. To a regular Bitcoin client, these transactions look like normal Bitcoin transactions, with one party sending another party a very small amount of Bitcoin. A Counterparty node (which runs the Bitcoin client along with the Counterparty client software) will recognize and interpret the data in these Bitcoin transactions based on specific rules. From this, it constructs its own ledger of Counterparty transactions that it has seen on the Bitcoin network. To better help understand this, here is a record of a Counterparty transaction where one address is sending 48 SJCX tokens (a custom token used by Storj) to another address. Here is what this transaction looks like to a blockchain.info, a popular Bitcoin block explorer. You can see that while it is indeed a Bitcoin transaction, the amount of Bitcoin moved is small. In reality, the BTC spent is just enough to compensate the Bitcoin miners to include the transaction in a block. Essentially, the user that sent the transaction is paying the Bitcoin network to record and secure this embedded Counterparty data.
Yes. Another way to think of it is similar to a Russian nesting doll, where the bigger doll would be the Bitcoin transaction, and the next doll (inside of it) would be a Counterparty transaction. This embedding method is technically known as embedded consensus."
"A cryptocurrency based on Bitcoin, the work of Satoshi Nakamoto, with various improvements such as a two-tier incentivized network, known as the Masternode network. Included are other improvements such as Darksend, for increasing fungibility and InstantX which allows instant transaction confirmation without a centralized authority."
"Distributed, token-incentivized timestamping systems ledgers such as Bitcoin have become a mainstay of modern finance. We have implemented a platform combining elements of proof-of-work (PoW) and proof-of-stake (PoS) blockchains in an attempt to garner the benefits of both systems. Less major change to our consensus network include additional elliptic curve signature suites, refinement and modification of the existing scripting language, added extensibility in multiple areas to support future changes to the protocol, and distributed stake pooling."

This ensures the best gambling experience ever."
"Elastos aims to create a new kind of Internet, powered by blockchain technology. On this new Internet, people will be able to own digital assets and generate wealth from them. Today, there is a seemingly infinite supply of digital books, movies, music and games. But people do not necessarily own their digital property. You can purchase a digital book, for example, but you can’t sell it to anyone else. So, do you really own it? Elastos wants to make digital assets scarce, identifiable and tradable. Property rights pave the way for wealth creation, and Elastos intends to build a new World Wide Web that respects those rights."
"Electroneum is the first cryptocurrency that is designed around mobile ubiquity. To put it another way, it is designed for the estimated 2 billion smartphone users around the world.

"A peer-to-peer network, enabling different parties to jointly store and run computations on data while keeping the data completely private. Enigma’s computational model is based on a highly optimized version of secure multi-party computation, guaranteed by a verifiable secret-sharing scheme. For storage, we use a modified distributed hashtagable for holding secret-shared data. An external blockchain is utilized as the controller of the network, manages access control, identities and serves as a tamper-proof log of events. Security deposits and fees incentivize operation, correctness and fairness of the system. Similar to Bitcoin, Enigma removes the need for a trusted third party, enabling autonomous control of personal data.For the first time, users are able to share their data with cryptographic guarantees regarding their privacy."
"Current technologies for blockchain fall short of providing what developers and end-users need in order to contract together and to build large scale businesses. We propose EOS, a performance-based and self-governing blockchain that provides an operating system for building large-scale consumer facing distributed applications. This paper outlines the context, vision and software architecture underlying EOS, which we are building to serve a broad and diverse group of users with smart business."

"Ethereum Classic is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference. Ethereum Classic is a continuation of the original Ethereum blockchain - the classic version preserving untampered history; free from external interference and subjective tampering of transactions."
"The intent of Ethereum is to create an alternative protocol for building decentralized applications, providing a different set of tradeoffs that we believe will be very useful for a large class of decentralized applications, with particular emphasis on situations where rapid development time, security for small and rarely used applications, and the ability of different applications to very efficiently interact, are important. Ethereum does this by building what is essentially the ultimate abstract foundational layer: a blockchain with a built-in Turing-complete programming language, allowing anyone to write smart contracts and decentralized applications where they can create their own arbitrary rules for ownership, transaction formats and state transition functions. A bare-bones version of Namecoin can be written in two lines of code, and other protocols like currencies and reputation systems can be built in under twenty. Smart contracts, cryptographic "boxes" that contain value and only unlock it if certain conditions are met, can also be built on top of the platform, with vastly more power than that offered by Bitcoin scripting because of the added powers of Turing-completeness, value-awareness, blockchain-awareness and state."
"Factom is a distributed, autonomous layer residing on top of the Bitcoin blockchain. The goal of Factom is to provide the power of Bitcoin’s blockchain to a nearly unlimited range of Applications and uses. Further, Factom is architected such that its users do not need any cryptocurrency whatsoever. A distributed, immutable ledger is the radical, foundational, and unprecedented technology represented by the Bitcoin blockchain. The dream of many is to extend the honesty inherent to an immutable ledger validated by math to chaotic, real-world interactions. By allowing the construction of unbounded ledgers backed by the blockchain, Factom extends the benefits of the blockchain to the real world."

"Grid+ is developing a hardware and software stack to create a secure Ethereum-enabled gateway and connect Internet-of-Things (IoT) devices. The hardware gateway, or “smart energy agent”, is an Internet-enabled, always-on appliance which will securely store cryptocurrencies and process payments for electricity in real-time, which we refer to in this Whitepaper as “The Smart Agent”. The Smart Agent will also be able to programmatically buy and sell electricity on behalf of the user and intelligently manage smart loads (e.g. Tesla Powerwall or Nest thermostat). The software stack will work in conjunction with the Smart Agent to make payments, using a combination of Grid+ designed payment-channels and a Raiden network hub (when available). Grid+ is developing a system architecture that allows a typical user to leverage the advantages of cryptocurrencies while remaining unaware of their use. Interestingly, the implementation of a secure, always-on system, with low friction payment rails, provides a missing piece of critical infrastructure in the broader cryptocurrency ecosystem. The Grid+ infrastructure has many uses beyond electricity and will be key to enabling the widespread adoption of cryptocurrencies."
"The Grøstl hash function is a finalist in the SHA-3 competition organized by NIST. In this paper, we describe a number of implementation techniques and tricks for Grøstl. They allow us to develop a range of efficient implementations for various platforms, from 8-bit microcontrollers to modern desktop processors using 256-bit AVX instructions. These results demonstrate the implementation flexibility of the algorithm and we hope will inspire further optimizations and ports to other platforms. The information in this paper will also be useful for developers planning to implement Grøstl efficiently on the platform of their choice. Furthermore, we believe also hardware implementations may benefit from the optimization techniques presented in this paper."

"Since the late 2000s, when Kickstarter (2009) and Indiegogo (2008) were launched, the world has been watching the rise of crowdfunding. Many project creators believe that crowdfunding platforms are just a simple way to raise funds for a project without needing to attract fickle VC investment. However, in fact there are lot of limitations and obstacles. First, traditional crowdfunding platforms do not accept projects from countries where they have no presence. Second, they charge high commissions (15-20%), as do the payment systems people must use to contribute with. Third, they are overwhelmed with 'failed' projects that let down the backers and the platform itself. Fourth, the larger crowd-funding platforms became all about big companies with strong marketing, rather than about creators with bright ideas, but no marketing budget. The crypto-revolution that is happening now will change things, facilitating fundraising and making it as easy and simple as it is supposed to be. Decentralization, crypto-currency, and smart-contracts are the new solutions for a project to raise funds. The fundraisers will no longer be dependent on the platforms, KICKICO is the first up-and-running blockchain fundraising platform that offers comprehensive solutions for ICOs, crowdfunding, and crowdinvesting."
"Kik has been a leading innovator in the chat space since the first million people signed up for the chat application in 2010. Kik was the first chat app to become a platform in 2011, and the first Western chat platform to integrate bots in 2014. Throughout 2015 and 2016, Kik also experimented with a form of digital currency on its platform, called Kik Points. As a company, Kik has been searching for a sustainable monetization model that does not compromise user experience or privacy. Rather than opt for mass display advertising or the selling of consumer data, Kik has decided to adopt a decentralized organizational model. Its goal is to encourage the development of a digital services ecosystem that is fair and open. Kik prefers to be a participant rather than a landlord in this user-first economy. To foster an ecosystem that is not only open and decentralized but also more compelling than its traditional counterpart, Kik must create a series of new products, services, and systems. Building a decentralized system is a complex process, and the transition to it must be done in a measured and responsible way over time. The following sections of this paper outline Kik’s plan for launching an entirely new platform: the Kin Ecosystem."

"Bitcoin'  has been a successful implementation of the concept of p2p electronic cash. Both professionals and the general public have come to appreciate the convenient combination of public transactions and proof-of-work as a trust model. Bitcoin has effectively proved that electronic cash can be as simple as paper money and as convenient as credit cards. Unfortunately, Bitcoin suffers from several deficiencies. For example, the system's distributed nature is inexorable, preventing the implementation of new features until almost all of the network users update their clients. In this paper, we study and propose solutions to the main deficiencies of Bitcoin. We believe that a system taking into account the solutions we propose will lead to a healthy competition among different electronic cash systems. We also propose our own electronic cash, \CryptoNote', a name emphasizing the next breakthrough in electronic cash."

"Bitcoin has proven that a peer-to-peer electronic cash system can indeed work and fulfill payments processing without requiring trust or a central mint. However, for an entire electronic economy to be based on a fully decentralized, peer-to-peer solution, it must be able to do the following: process transactions securely, quickly and efficiently, at the rate of thousands per hour or more; provide incentives for people to participate in securing the network; scale globally with a minimal resource footprint; offer a range of basic transaction types that launch cryptocurrencies past the core feature of a payment system alone; provide an agile architecture that facilitates the addition of new core features, and allows for the creation and deployment of advanced applications; and be able to run on a broad range of devices, including mobile ones.

"Imagine if there were a solution that provided the scalability that we all know this sector needs, we’re not talking about 10, 100, or even a thousand transactions being processed per second. What if there was a blockchain that could run a minimum of 40,000 transactions per second with future enhancements that are even higher? What if there were a secure and fundamentally sound platform, built upon the lessons learned from initial efforts of Bitcoin and Ethereum that would allow developers of all mediums and categories to build on that platform? What if that platform were built not on proof of work but proof of stake? Yes – we’ve heard the rumors about groups coming out with bits and pieces of those solutions but there simply isn’t one that can promise all that and be less than a year to market."
Request Network (REQ)
"Request is a decentralized network that allows anyone to request a payment (a Request Invoice)for which the recipient can pay in a secure way. All of the information is stored in a decentralized authentic ledger. This results in cheaper, easier, and more secure payments, and it allows for a wide range of automation possibilities. To become the backbone of world trade, Request integrates a general ledger (in the accounting sense of the term), which is:Universal because it is designed to support 100% of global transactions, regardless of currency, legislation or language. Request is built to last. Smart because unlike an existing standard accounting book, Request is at the origin of the exchanges and integrates a computerized trade code, as well as the management of a multitude of payment terms. Today, their absence makes the whole system inefficient and absolutely unready for the digital and IoT (Internet Of Things) revolution that is taking place. Request can be seen as a layer on top of Ethereum, which allows requests for payments that satisfy a legal framework.It is also possible to see currencies as tools to complete Request transactions. In this sense,Request is more global than any currency."
"Revain is the first review platform that implements the blockchain technology in order to ensure feedback legitimacy and as a backbone for the economic model which ensures that all feedback is genuine and legitimate.

Ripio Credit Network (RCN)
"Ripio Credit Network (“RCN”) is a protocol based on smart contracts and blockchain technology, which brings enhanced transparency and reliability in credit and lending.The protocol enables connections between lenders and borrowers located anywhere in the world, regardless of currency. By reducing the traditional banking brokerage costs and management fees, RCN aims to allow better conditions for both sides, creating a better credit alternative than anything available today. By including an intermediary agent (the “Cosigner”), the RCN seeks to neutralize the lender’s credit risk and, in case of a default, provide an alternative mechanism for managing the debt collection in the borrower’s country of residence."
"SALT is a membership based lending and borrowing network that allows users to leverage their blockchain assets to secure cash loans. Our Secured Automated Lending Technology is a protocol and asset agnostic architecture designed to adapt to the constantly growing class of blockchain assets. The system is designed such that, if you have an asset you want to hold onto, you can borrow the asset you want to spend, regardless of credit history or geographic constraints. The SALT Platform is automated, efficient, and cryptographically secure. It offers a compelling solution to the problem many consumers face when they need or want cash to make a purchase, but do not wish to liquidate their assets. Instead of selling, SALT enables the members of the SALT Lending Platform (Members) to leverage the value of certain digital assets, thereby giving them access to cash, offsetting tax events, avoiding exchange fees and maintaining their long position in the asset they hold. SALT is a lending platform specifically designed for blockchain assets; operating as a second layer protocol which sits atop any public or permissioned blockchain, allowing the underlying asset to be used as collateral for access to credit."

Steem is the first cryptocurrency that attempts to accurately and transparently reward an unbounded number of individuals who make subjective contributions to its community."
Stellar Lumens (XLM)
"This paper introduces a new model for consensus called federated Byzantine agreement (FBA). FBA achieves robustness through quorum slices—individual trust decisions made by each node that together determine system-level quorums. Slices bind the system together much the way individual networks’ peering and transit decisions now unify the Internet. We also present the Stellar Consensus Protocol (SCP), a construction for FBA. Like all Byzantine agreement protocols, SCP makes no assumptions about the rational behavior of attackers. Unlike prior Byzantine agreement models, which presuppose a unanimously accepted membership list, SCP enjoys open membership that promotes organic network growth. Compared to decentralized proof of-work and proof-of-stake schemes, SCP has modest computing and financial requirements, lowering the barrier to entry and potentially opening up financial systems to new participants."
"A peer-to-peer cloud storage network implementing client-side encryption would allow users to transfer and share data without reliance on a third party storage provider. The removal of central controls would mitigate most traditional data failures and outages, as well as significantly increase security, privacy, and data control. Peer-to-peer networks are generally unfeasible for production storage systems, as data availability is a function of popularity, rather than utility. We propose a solution in the form of a challenge-response verification system coupled with direct payments. In this way we can periodically check data integrity, and offer rewards to peers maintaining data. We further propose a model for addressing access and performance concerns with a set of independent or federated nodes."
"Stratis will take a similar approach to blockchain deployment, enabling organisations to provision their own private blockchains, tailored to their precise needs but secured on the parent Stratis chain. This approach means there are few unnecessary overheads whilst allowing businesses to secure the benefits of a blockchain - based solution, developing services via powerful APIs and lite web-based clients."

"While Bitcoin (Peer-to-Peer Electronic Cash) [Nak] solved the double spend problem and provided work with timestamps on a public ledger, it has not to date extended the functionality of a blockchain beyond a transparent and public payment system. Satoshi Nakamoto’s original reference client had a decentralized marketplace service which was later taken out due to a lack of resources [Deva]. We continued with Nakamoto’s vision by creating a set of commercial grade services supporting a wide variety of business use cases, including a fully developed blockchain-based decentralized marketplace, secure data storage and transfer, and unique user aliases that link the owner to all services controlled by that alias."
"At TenX, we strive to offer the user access to as large as possible a range of blockchain assets at a maximum degree of convenience, while adhering to the highest security standards in the ecosystem.

"TRON is an attempt to heal the Internet. Regardless of the inappropriateness of the attempt in the opinion of giants, or the failure arising out of an overestimation of the ability in the opinion of ordinary people, or success in the thing or not. We believe, users must have the ownership and power of disposal of the data they create, which will not be assigned to the platform, and users freely own all digital information. We believe, users must have the final power to make a decision on reading and gaining of contents, and information must be distributed on a free and volunteer basis, at the option of users. We believe, users must be entitled to the incentives of digital assets using data on a free basis, which will be no longer bound by any platform and will be protected by the decentralized internet. All of these are subject to a decentralized protocol called TRON."

It allows non-technical individuals & entities to quickly create, enter and manage smart contracts directly with others without an authoritative 3rd party. It was the first of its kind written on a public or private blockchain."
"Committed to the decentralisation Satoshi originally dreamed of, Vert has consistently evolved over time to combat the threats to this dream. As a result, one of our main features is ASIC resistance, having forked successfully to a new proof of work algorithm called Lyra2RE upon discovering that Scrypt-N ASICs were being developed, and Lyra2reV2 after discovering a botnet. We believe that by keeping the mining process in the hands of those with generalised, low-risk, consumer grade hardware, we can lower the entry requirement for miners, increasing the number of individuals mining the coin which in turn leads to true decentralisation."
"The whole system of the Value Internet of Things can be divided into two parts: hardware and software. The hardware includes the RFID tag chips and the RFID reader chips. The RFID tag acts as the interface for all assets to be connected to the chain, and the reader chip is a bridge for all assets to be connected to the chain and can be used as a node on the chain. The software includes the Waltonchain software system, the Walton protocol and the Walton coin. With the combination of software and hardware, the Value Internet of Things can really achieve the connection of all things to the chain and the digitalization of all assets."
