## What Is Horizen (ZEN)?

ZEN is the governance and utility token for Horizen, a zero-knowledge-enabled network of blockchains powered by the largest node infrastructure in the industry. Blockchain interoperability is enabled by the Zendoo protocol, which uses SNARK-verification and allows for complete flexibility in sidechain type, consensus, and speed. Cryptographic verification of networked chains offers massive scale, and the network currently supports up to 10,000 sidechains with a throughput limit of 10,000,000 TPS.

Zendoo makes Horizen a permissionless network of blockchains. Developers can deploy their blockchains within the ecosystem using a variety of SDKs. In 2023, the ecosystem team launched Horizen EON, a public proof-of-stake sidechain and an EVM-compatible smart contracting platform that allows developers to efficiently build and deploy dapps on the Horizen ecosystem, while benefiting from the Ethereum ecosystem. Since going live with Horizen EON, DeFi projects including SpookySwap, Ascent Exchange, and Yuzu have successfully integrated into the Horizen ecosystem. Get started on Horizen EON today!

Horizen's native cryptocurrency, ZEN, is a mineable PoW coin currently trading on major exchanges, including Coinbase and Binance. ZEN can be staked to participate in Horizen's nearly 50,000 full node network.

While ZEN was previously a privacy token, following ZenIP 42204 in June of 2023, the network removed its existing privacy features in favor of moving towards a vision of adaptability and responsible, scalable growth.

## What Makes Horizen Unique?

Horizen is known for its expertise in zero-knowledge-based blockchain technology. The Horizen team has made several advancements in the cryptography space, including the release of one of the first zero-knowledge-based scalability solutions called Zendoo.

Their blockchain network provides a unique sidechain solution that allows developers to build their own scalable blockchains with the ability to support tens of thousands of transactions per second while maintaining true decentralization across tens of thousands of nodes. Horizen also features Zendoo, a sidechain system that enables the deployment of thousands of independent sidechains that communicate with the mainchain and each other. Horizen has expanded its ecosystem with the release of Horizen EON, an EVM compatible smart contracting platform with lots of integrations in the DeFi, RWA, and NFT space. 

Blockchain transactions are verified by network nodes, which requires significant computational power. This is why most blockchain networks have a cap on the number of transactions they can process at any given time. However, developers on Horizen can operate more than 10,000 independent blockchains simultaneously while handling up to 10 million transactions per second across all sidechains (an average TPS of 1,000 per chain). This is largely due to Horizen’s node network being one of the largest and most distributed networks in the industry. This enables their network to be fully decentralized while maintaining high throughput for transactions across the network.

Horizen is decentralized on the technical level and has moved most of its organization to a DAO structure. Horizen uses the ZenIP process to standardize the process of suggesting major changes to the Horizen code base and ecosystem.

Today, the Horizen team is focused on building a modern, scalable solution for settlement that helps increase modularity and sets the stage for greater collaboration in Web3.

ZEN is the native cryptocurrency for the Horizen ecosystem.

## How Many Horizen (ZEN) Coins Are There in Circulation?

Horizen has a maximum supply of 21,000,000 coins, of which just over 14,468,625 are in circulation as of December 2023.

Horizen has one of the largest node networks with a multi-tiered node system. The operators receive 20% of the total block subsidy, and the dispersed node network provides an extensive infrastructure to operate an ecosystem of both applications and sidechains.

When it comes to mining ZEN, it is an ASIC-mineable cryptocurrency that employs the Equihash algorithm. Block rewards 60% miners, 20% treasury, and 20% nodes.

## How Is the Horizen Network Secured?

Horizen utilizes a combination of Proof-of-Work in their mainchain and Proof-of-Stake in their sidechains. Each PoS sidechain built on the Horizen network is pegged to the mainchain and runs simultaneously. The mainchain acts as a ‘truth engine’ for all blockchains built on the network.

Horizen uses zk-SNARKs to allow the communication between sidechains and the mainchain without having the mainchain know the sidechain logic and the internal structure. This approach keeps the mainchain completely decoupled from the sidechain’s logic and allows the whole system to scale possible applications and global transaction throughput. 

The Horizen blockchain network uses secure nodes which are TLS encrypted to enable secure inter-node communication. ZEN uses the Equihash consensus algorithm, which supports ASIC mining and offers shielded transactions that can mask the sender, recipient, and value transacted.

#Horizen ($ZEN) is the zero-knowledge enabled network of blockchains.

Zcash is a decentralized cryptocurrency focused on privacy and anonymity. It uses the zk-SNARK zero-knowledge proof technology that allows nodes on the network to verify transactions without revealing any sensitive information about those transactions.

Contrary to a common misunderstanding, the majority of cryptocurrencies on the market, including Bitcoin (BTC), are not anonymous, but rather pseudonymous; while they do not explicitly reveal the identities of their users, each user has their own public address or addresses which can be traced back to them via the methods of data science and blockchain forensics.

Zcash transactions, on the other hand, still have to be relayed via a public blockchain, but unlike pseudonymous cryptocurrencies, ZEC transactions by default do not reveal the sending and receiving addresses or the amount being sent. There is an option, however, to reveal this data for the purposes of auditing or regulatory compliance.

Zcash was first released on October 28, 2016, and it was originally based on Bitcoin’s codebase.

Ontology is a project designed to bring trust, privacy, and security to Web3 through decentralized identity and data solutions. It is building the infrastructure to provide trusted access to Web3, allowing individuals and enterprises to rest assured that through regulatory compliant digital identity solutions, users and their privacy come first.

The Ontology blockchain is a high speed, low cost public blockchain. It is designed to bring decentralized identity and data solutions to Web3, with the goal of increasing privacy, transparency, and trust. To achieve this, users and enterprises are provided with the flexibility to build blockchain-based solutions that suit their needs, while also ensuring regulatory compliance. Through Ontology’s Ethereum Virtual Machine (EVM), Ontology ensures frictionless compatibility with Ethereum, the first step in the creation of the Ontology Multi-Virtual Machine and further interoperability for the chain.

At its launch, Ontology chose to forego the popular initial coin offering (ICO) model in favor of a series of community distributions and airdrops of its ONT cryptocurrency.

This helped to quickly establish both organic price discovery and a passionate community and helped the project to avoid subsequent regulatory scrutiny.

For example, for a brief period any person who signed up for the Ontology newsletter received an airdrop of free 1,000 ONT, which reached a value of $10 per token soon after the token became listed on major exchanges like Binance.

Ontology launched its own MainNet on June 30, 2018 and has been up and running smoothly since.

Compound is a DeFi lending protocol that allows users to earn interest on their cryptocurrencies by depositing them into one of several pools supported by the platform.

To learn more about this project, check out our deep dive of Compound.

When a user deposits tokens to a Compound pool, they receive cTokens in return. These cTokens represent the individual’s stake in the pool and can be used to redeem the underlying cryptocurrency initially deposited into the pool at any time. For example, by depositing ETH into a pool, you will receive cETH in return. Over time, the exchange rate of these cTokens to the underlying asset increases, which means you can redeem them for more of the underlying asset than you initially put in — this is how the interest is distributed.

On the flip side, borrowers can take a secured loan from any Compound pool by depositing collateral. The maximum loan-to-value (LTV) ratio varies based on the collateral asset, but currently ranges from 50 to 75%. The interest rate paid varies by borrowed asset and borrowers can face automatic liquidation if their collateral falls below a specific maintenance threshold.

Since the launch of the Compound mainnet in September 2018, the platform has skyrocketed in popularity, and recently passed more than $800 million in total locked value.

Compound

Waves is a multi-purpose blockchain platform which supports various use cases including decentralized applications (DApps) and smart contracts.

Basic Attention Token, or BAT, is the token that powers a new blockchain-based digital advertising platform designed to fairly reward users for their attention, while providing advertisers with a better return on their ad spend.

To learn more about this project, check out our deep dive of Basic Attention Token.

This experience is delivered through the Brave Browser, where users can watch privacy-preserving adverts and receive BAT rewards for doing so. On the other hand, advertisers can deliver targeted ads to maximize engagement and cut down losses due to ad fraud and abuse.

The Basic Attention Token itself is the unit of reward in this advertising ecosystem, and is exchanged between advertisers, publishers and users. Advertisers pay for their advertising campaigns in BAT tokens. Out of this budget, a small portion is distributed to advertisers, while 70% is distributed to users — whereas the intermediaries that typically drive up advertising costs are cut out of the equation to improve cost-efficiency.

Basic Attention Token launched in 2017 following one of the fastest sell-out initial coin offerings (ICOs) of all time, with the platform raising a total of $35 million in under a minute. Since then, it has rolled out its attention-based advertising experience to users in most countries through its Brave Rewards program.

As of November 2020, the United States, the United Kingdom and Canada had the most active advertising campaigns.

Band Protocol is a cross-chain data oracle platform that is able to take real-world data and supply it to on-chain applications, while also connecting APIs to smart-contracts to facilitate the exchange of information between on-chain and off-chain data sources.

By supplying reputable, verifiable real-world data to blockchains, Band Protocol unlocks a range of new use cases for developers to explore — since they can now use any type of real-world data as part of their decentralized application (DApp) logic, including sports, weather, random numbers, price feed data and more.

Band Protocol initially launched as an ERC-20 project on the Ethereum blockchain in September 2019, but transitioned to the Cosmos network in June 2020 with the release of Band Protocol 2.0. The new protocol is built on BandChain using the Cosmos SDK. Oracle nodes on BandChain not only relay data but are also involved in block production/validation, giving them a dual role.

BAND is the native token of the Band Protocol ecosystem and is used as collateral by validators involved in fulfilling data requests, as well as the main medium of exchange on BandChain — being used to paying for private data.

Band Protocol

OMG Network, formerly known as OmiseGo, is a non-custodial, layer-2 scaling solution built for the Ethereum blockchain. As an Ethereum scaling solution, OMG Network is designed to allow users to transfer ETH and ERC20 tokens significantly faster and cheaper than when transacting directly on the Ethereum network.

The network is based on a novel scaling solution called MoreViable Plasma, which uses a sidechain architecture to group several transactions off-chain into a batch, which can then be verified as a single transaction on the Ethereum root chain. According to OMG Network, this technology has the potential to scale Ethereum to thousands of transactions per second (TPS) — instead of the 10 to 14 tps Ethereum 1.0 is currently capable of.

The network is powered by the OMG utility token, which can be used as one of the payment methods for fees on the OMG Network, and will eventually be stakable — helping to secure the network in return for rewards.

OMG Network

Self-described as "Polkadot's wild cousin," Kusama is an experimental blockchain platform that is designed to provide a massively interoperable and scalable framework for developers.

Kusama is built on Substrate — a blockchain building kit developed by Parity Technologies. Kusama has almost the same codebase as Polkadot — one of the most successful interoperable blockchains.

By deploying on Kusama, fast-paced projects gain access to a highly scalable, interoperable sharded network, with features that are not yet available on Polkadot. To that end, Kusama describes itself as a “canary network.”

The platform is designed to provide a testbed for developers looking to innovate and deploy their own blockchain and can be used as a preparatory network before launching on Polkadot — though many projects opt to stick with Kusama for their final product.

Kusama benefits from a low barrier to entry for deploying parachains, low bond requirements for validators, and is most commonly used by early-stage startups and for experimentation.

Balancer is an automated market maker (AMM) that was developed on the Ethereum blockchain and launched in March 2020. It was able to raise a $3M seed round by Placeholder and Accomplice. Balancer protocol functions as a self-balancing weighted portfolio, price sensor and liquidity provider. It allows users to earn profits through its recently introduced token ($BAL) by contributing to customizable liquidity pools.

To learn more about this project, check out our deep dive of Balancer(https://coinmarketcap.com/alexandria/article/what-is-balancer.

The protocol operates a few types of pools:

Private pools give the owner governance over the pool, and make the person the sole contributor of liquidity to the pool. Also, all the parameters are mutable by the owner.

Shared pools are for those who want to become liquidity providers (LPs). The LPs are rewarded with the Balancer Pool Tokens (BPTs).

Smart pools are similar to private pools but are controlled by a smart contract. They also reward using BPTs and allow anyone to contribute liquidity to the pool.
