The Cosmos network consists of many independent, parallel blockchains, called zones, each powered by classical Byzantine fault-tolerant (BFT) consensus protocols like Tendermint (already used by platforms like ErisDB). Some zones act as hubs with respect to other zones, allowing many zones to interoperate through a shared hub. The architecture is a more general application of the Bitcoin sidechains concept, using classic BFT and Proof-of-Stake algorithms, instead of Proof-of-Work. Cosmos can interoperate with multiple other applications and cryptocurrencies, something other blockchains can’t do well. By creating a new zone, you can plug any blockchain system into the Cosmos hub and pass tokens back and forth between those zones, without the need for an intermediary. For example, if you wanted to trade bitcoins for ether today, you would have to sell your bitcoins for a fiat currency on an open exchange and then use that fiat currency to buy ether on another exchange. The problem is, many of our exchanges today are plagued by hacks, theft, and cons. Two prime examples are what happened at Mt. Gox and more recently Bitfinex.

WeTrust is a collaborative saving and insurance platform. It is autonomous, frictionless, and decentralized. WeTrust utilizes the Ethereum blockchain to create a full-stack financial system that leverages existing social capital and trust networks, eliminating the need of a “trusted third party”, which allows for lower fees, improved incentive structures, decentralized risks, and a greater amount of capital to reside among the participants.

Humaniq is a financial ecosystem built on blockchain, focused on simply and quickly connecting unbanked people to the global economy. It combines blockchain bank as a core platform for financial services and technology start-ups, biometrics that replaces passports and signatures, ICO and distributed ownership instead of shareholders, and an investment fund for third-party start-up acquisition and acceleration.

TaaS is a tokenized closed-end fund designed to reduce risks and technical barriers of investing in blockchain space. Built on a profit-sharing smart contract, TaaS introduces Token-as-a-Service business model, allowing investors to subscribe to fund’s income stream. TaaS built an innovative Cryptographic Audit technology to become transparent fund dedicated to cryptocurrencies and tokens.

Decentralized platform for the registration and distribution of content that certifies the authorship and license of any work or creation making them indelible. At Creativechain, they are challenging the centralized power of traditional systems of copyright management entities. They offer a public and transparent alternative to intellectual property registration using revolutionary distributed technology blockchain. They have designed an alternative cryptocurrency with the aim of encouraging the economic empowerment of creative people vis-à-vis the traditional banking system.

BOScoin is a congressional decentralized cryptocurrency platform for “Trust Contracts” BOScoin is a cryptocurrency that utilizes the blockchain and numerous new technologies to solve persistent issues in decentralized systems.

Peerplays is a solution for provably fair blockchain-based gaming that allows users to design their own specialized tokens or chips, buy or sell gateway tokens for popular cryptocurrencies like Bitcoin or Ether and then wager these tokens in on-chain games.

Aragon lets you manage entire organizations using the blockchain. This makes Aragon organizations more efficient than their traditional counterparties.By making it possible for everyone in the world to organize, we are enabling the borderless, permissionless creation of value.

The VIVA Project is more than about cryptocurrency. It's the currency that guarantees price stability by direct control of the supply using smart contracts. Building off of a multi-million dollar development project called Hyperledger Fabric (funded by IBM and other industry leaders) VIVA multidimensional blockchain graph raises the bar for blockchain technology. Unlike Proof of Work and Proof of Stake consensus algorithms, VIVA concept of Proof of Authority does not depend on energy consuming mining farms nor top-heavy stake holders who dominate the ecosystem.

The Quantum Resistant Ledger (QRL) project is a public blockchain ledger designed to be specifically secure against quantum computing (QC) advances. Unlike existing ledgers, such as bitcoin or ethereum, the QRL is specially designed to use a form of post-quantum secure signature for transactions called XMSS. The QRL also uses a low power proof-of-stake (POS) algorithm which again utilises iterative hash-chains and provably secure hash-based pseudo random number functions. The POS algorithm is designed to have zero reliance upon conventional signatures which are vulnerable to a sufficiently powerful QC and allows nodes to run on low power devices such as raspberry PI’s or laptops and passively earn income by staking.
