## What Is Handshake (HNS)?

Handshake is a decentralized permissionless system that is intended to incentivize a distributed network of computers to operate a system for domain name ownership. 

 

Under Handshake, every peer is tasked with validating and managing the root DNS naming zone, with the objective of providing an alternative to current certificate authorities and naming systems. 

 

Different participants across the internet such as social networking handles and domains rely on a centralized approach. This means the systems depend on a system of honesty — and are still prone to cyber attacks and fraud. 

 

Handshake aims to eradicate this problem by creating a decentralized internet that relies on a peer-to-peer system. 


### Who Are the Founders of Handshake? 

Joseph Poon and Andrew Lee are the two main co-founders of Handshake. 

Lee quit a job at Merrill Lynch to co-found Purse — one of the largest marketplaces for Bitcoin in early 2014. As Purse expanded, he began to explore other ways of innovating in the marketplace and investing in infrastructure.

He and Poon had been discussing the ideas underpinning Handshake for years before they co-founded the company. 

Aside from developing Handshake, Poon co-wrote the Plasma Papers in collaboration with Vitalik Buterin, the co-founder of Ethereum. 

Poon worked at a Big Four accounting firm before becoming involved in the crypto space, while in between jobs. He’s also the co-creator of the Lightning Network and Plasma. 

Other co-founders include Boyma Fahnbulleh and Christopher Jeffrey.


#### What Makes Handshake Unique?

One of the most unique features of Handshake is that it is not a blockchain project looking to fully decentralize current DNS infrastructure. It is rather about decentralizing the root zone — and/or the top-level domains. 

This is because apart from the root zone, the entire of DNS is already decentralized. 

Handshake’s white paper states: “the Handshake naming protocol differs from its predecessors in that it has no concept of _namespacing_ or subdomains at the consensus layer. Its role is not to replace all of DNS, but to replace the root zone file and the root servers.”

A key concept about Handshake is that it aims to decentralize or reduce dependence on the Internet Corporation for Assigned Names and Numbers (ICANN.)

ICANN was launched in 1998 as a non-profit partnership made of people across the globe, with the aim of keeping the internet more secure. 

Handshake instead aims to use a decentralized application based on Proof-of-Work principles to improve the security of the internet.

#### How Many Handshake Coins Are There in Circulation?

The maximum supply of Handshake coins is fixed at 2.04 billion — and at present, there are approximately 355 million coins in circulation.


### How Is Handshake Secured?

Handshake is secured using the unspent transaction output (UTXO) of the blockchain and uses the principles of proof-of-work (PoW) in the same way as Bitcoin.

The naming system comprises on-chain smart contract features which are known as covenants, which are intended to limit the use of future transaction output. 


### Where Can You Buy Handshake (HNS)?

Handshake is traded on more than a dozen exchanges. The most known exchanges for buying and selling Handshake are Bittrex, Gate.io, BigOne, MXC.com and ZB.com. [Read more about how to convert fiat currencies to crypto here.](https://coinmarketcap.com/how-to-buy-bitcoin/)

Orchid (OXT) is the native token of Orchid, a cryptocurrency-powered virtual private network (VPN).

Launched in December 2019, Orchid describes itself as the world’s first incentivized, peer-to-peer privacy network.

Its aim is to overcome internet freedom limitations by using cryptocurrency payments to allow anyone to purchase bandwidth from any participating provider. This is done using so-called probabilistic nanopayments, which occur using OXT, an ERC-20 standard token on Ethereum.

Regular payments to providers occur off-chain, allowing Orchid to avoid problems with congestion and gas fees on the Ethereum network.

The service is pay-per-use, meaning that users only have to contribute funds when they actually connect, instead of paying monthly or annual fees.

Nervos Network (CKB) is an open-source public blockchain ecosystem. Its goal is to create a peer-to-peer (P2P) crypto-economy network where users can access a wide range of provably secure blockchain services and capabilities.

The Nervos mainnet launched in November 2019 with a novel dual-layer architecture. There’s a base layer where the consensus mechanism operates and smart assets are stored, and a computation layer where transactions are processed.

The base layer, also known as the Common Knowledge Base, has its own cryptocurrency called CKByte (CKB). It uses the Proof-of-Work (PoW) consensus mechanism and drives the Nervos ecosystem. It is used to pay miners for keeping the network safe, managing network resources, and letting users store things on the network.

The Nervos Network allows developers to create decentralized applications (dApps) that can operate on various blockchain systems. Any of the network layers can be used to run both decentralized apps and smart contracts.

Efinity is a cross-chain NFT platform developed by Enjin and built on Polkadot. Efinity was created as the next generation blockchain for digital assets with the aim of adapting to the challenges of the world of non-fungible tokens (NFTs), according to the project.

The main specialization of the Efinity project is the NFT space. With the protocol, traders and gamers can create, distribute, transfer, sell and buy NFTs. Efinity aims to remove barriers to entry into the NFT space/decentralized gaming, and to simplify user experience and digital asset governance.

Efinity Token powers the entire Efinity ecosystem, EFI aims to prioritize the generation, transfer and purchase of tokens using an inter-chain infrastructure of protocols resulting in lower transaction fees. As for incentives, rewards on PoW blockchains with NFT functionality go to miners who create/trade tokens, thereby forming a community.

One of the long-term goals of Efinity is to become a hub for both fungible and non-fungible tokens, accepting tokens from any other chain, facilitating the pricing and exchange of NFTs, increasing transaction volume, and creating network effects.

In December 2021, the project won the Polkadot parachain auction, and in March 2022, Enjin launched their flagship parachain Efinity on the Polkadot Relay Chain — a blockchain platform that provides a decentralized parachain network where people havecontrol over their data and identity.

Siacoin (SC) is the native utility token of Sia, a blockchain-based distributed, decentralized cloud storage platform. Sia acts as a secure, trustless marketplace for cloud storage in which users can lease access to their unused storage space. Agreements and transactions are enforced with smart contracts, and Siacoin is the medium of exchange for paying for storage on the network. The main goal of the project is to become the "backbone storage layer of the internet."

Sia was originally announced in May 2014 before being revised and re-announced a year later in May 2015. It officially launched in June 2015.

DODO is a DeFi protocoldecentralized finance (DeFi) protocol and on-chain liquidity provider whose unique proactive market maker (PMM) algorithm aims to offer better liquidity and price stability than automated market makers (AMM).

The PMM pricing mechanism, which mimics human trading, utilizes oracles to gather highly accurate market prices for assets. It then provides enough liquidity close to these prices in order to stabilize the portfolios of liquidity providers (LP), lower price slippage and negate impermanent loss by allowing arbitrage trading as reward.

DODO also caters for new crypto projects with a free ICO listing through its Initial DODO Offering (IDO) which requires issuers to only deposit their own tokens.

DODO’s smart contract operates as an ERC20 token on the Ethereum network.

Smart contracts often struggle to access dependable data, but application programming interfaces (APIs) have been touted as a solution to this problem.

API3’s stated goal is to allow decentralized versions of APIs to be built, managed and monetized at scales. As blockchain technology plays an ever bigger role in the economy — from decentralized finance to supply chain management — the team behind this project says it has never been more important for smart contracts to provide “timely, reliable real-world data.”

The whitepaper for API3 was unveiled in September 2020 and set out the main problem that’s associated with APIs at present: connectivity. At present, there’s no way for smart contracts to establish a direct connection with APIs for the latest data — and this has led to an explosion in the popularity of oracles.

Although this has helped solve the problem to some extent, the industry has since been grappling with the “Blockchain Oracle Problem.” Oracles are a form of middleware that sit in between APIs and smart contracts — increasing costs and centralization. API3 intends to get around this problem by enabling API providers to operate their very own nodes.

API3’s token went live at the start of December following on from a token sale that generated tens of millions of dollars.

Serum is a decentralized exchange (DEX) and ecosystem that brings unprecedented speed and low transaction costs to decentralized finance (DeFi). (DeFi).

Serum is the only high-performant DEX designed around a fully on-chain central limit order book and matching engine. Ecosystem partners can compose with Serum’s on-chain orderbook to share liquidity and power their trading features for institutional and retail users.

In light of the popularity of DeFi and the growth of DEXes on Ethereum, users and developers are limited by high gas costs and slow transactions. Serum aims to resolve these traditional problems of DeFi, as well as issues of centralization, low capital efficiency, and liquidity segmentation.

The SRM utility and governance token enables users to receive discounts on protocol fees and voting rights; 100% of exchange fees flow back to SRM via buy-and-burn, staking rewards, and ecosystem grants.

MIR is the governance token of Mirror Protocol, a synthetic assets protocol built by Terraform Labs (TFL) on the Terra blockchain.

Mirror Protocol is decentralized from day 1, with the on-chain treasury and code changes governed by holders of the MIR token. TFL has no intention of keeping or selling MIR tokens, and there are no admin keys or special access privileges granted. The intent for this is to be a completely decentralized, community-driven project.

Mirrored assets are blockchain tokens that behave like "mirror" versions of real-world assets by reflecting the exchange prices on-chain. They give traders the price exposure to real assets while enabling fractional ownership, open access and censorship resistance as any other cryptocurrency. Unlike traditional tokens which serve to represent a real, underlying asset, mAssets are purely synthetic and only capture the price movement of the corresponding asset.

Mirrored assets provide the following advantages:

Global Accessibility: In most markets outside of Europe & North America, access to foreign equities and forex markets is highly limited. Crypto allows global accessibility without entry barriers.

Fractional Orders: In traditional finance, to execute a fractional order, multiple fractional orders are bundled together to execute a unitary transaction. The process of gathering all the orders into one requires additional waiting time. By utilizing the blockchain, orders volume is simply represented as a number on the blockchain, so there is no need for the intermediary bundling process.

Nearly-Instantaneous Order Execution: Oftentimes due to the lack of liquidity (price-time-priority order book algorithm), orders can take up to a day to fully execute. Given the fact that Mirror relies on liquidity provided by each individual asset pool, orders can be executed as fast as the blocktime of the network (~ 6 seconds).

Mirror Protocol

Secret (SCRT) is a privacy-oriented blockchain built on Cosmos. Its smart contracts are called Secret Contracts and allow DApps to use private data on Secret, similar to how smart contracts operate on other blockchains. However, Secret Contracts transfer encrypted inputs into encrypted outputs without exposing data. This is made possible thanks to the encrypted contract states during the execution.

Data privacy is guaranteed by combining encryption protocols and key management within a Trusted Execution Environment (TEE). This allows Secret Contracts to compete for several privacy-related use cases that traditional blockchains have found difficult to accommodate. For instance, private voting mechanisms or credit scoring applications become possible since they do not expose sensitive user data on-chain with Secret.

Audius is a decentralized music streaming protocol initially built on POA network, but now living on Solana. Audius was launched to remedy the inefficiencies of the music industry, which is plagued by intransparent music rights ownership and intermediaries standing between artists and their audience.

Audius aims to align the interests of artists, fans, and node operators through its platform powered by its native AUDIO token. Artists can upload music, stored and distributed by content and discovery nodes, that fans can listen to for free. Currently, Audius rewards content creators through rewards like featuring in the weekly trending lists. In the future, it plans to integrate stablecoins for artists to offer paid content, as well as artist tokens that give fans the ability to access exclusive content, potentially cooperating with platforms like Rally.

WAX (WAXP) is a purpose-built blockchain, released in 2017, that is designed to make e-commerce transactions faster, simpler and safer for every party involved. The WAX blockchain uses delegated proof-of-stake (DPoS) as its consensus mechanism. It is fully compatible with EOS.

The custom features and the incentive mechanisms developed by WAX are intended to optimize the blockchain’s utility specifically for use in e-commerce, with the goal of encouraging voting on proposals.

To make this possible, WAX created a suite of blockchain-based tools which decentralized application (DApp) marketplaces and non-fungible tokens can be built upon.

Services such as WAX Cloud Wallet, SSO and OAUTH support e-commerce operations, the latter being a native RNG service and a developer portal. WAX’s blockchain architecture supports 500-millisecond block time and zero-fee transactions for customers. It also makes use of voting rewards to incentivize participation in the selection of block producers and improvement proposals.

Energy Web Token (EWT) is the operational token behind the Energy Web Chain, a blockchain-based virtual machine designed to support and further application development for the energy sector.

Covalent leverages big-data technologies to create meaning from hundreds of billions of data points, delivering actionable insights to investors and allowing developers to allocate resources to higher-utility goals within their organization.

Instead of painstakingly sourcing data from a small handful of chains, Covalent aggregates information from across dozens of sources including nodes, chains and data feeds. The Covalent API then sources end-users with individualized data by wallet, including current and historical investment performance across all types of digital assets. Most importantly, Covalent returns this data in a rapid and consistent manner, incorporating all relevant data within one API interface.

Having achieved product-market fit, we are now planning to execute the next phase of Covalent, which is a progressive decentralization that will enable the Covalent Network to be owned and operated by its users. Of course, a critical piece to this is CQT.

CQT is the native token of the Covalent Network. It has three primary purposes:

CQT is a governance token, whereby token holders vote on proposals to change the system parameters.

CQT is a staking asset. Validators will earn fees for answering queries.

CQT is a network access token that fulfills data queries for users of the API.

Developer resources include:
