Zenon was launched as a POS/MS hybrid cryptocurrency in Mar 2019 and proposes a sharding-based decentralized architecture called the Network of Momentum (NoM), which aims to build upon existing blockchain and DAG architectures. 

Due to sharding, the network will reportedly be able to scale linearly as the number of nodes grows. The protocol differs from traditional blockchain consensus as transactions are not treated in batches, but asynchronously processed within shards, with the overall state of the network verified and validated at the end of each epoch (each epoch having a random timeframe). The network will also feature a Turing complete scripting language that will allow developers to build and run zApps, create digital assets, and allow low-resource devices to participate in the network.

Haven Protocol is similar to an offshore bank where users can create private tokens that represent stable and volatile assets, including commodities and fiat currencies (such as USD). The protocol is based on Monero, which focuses on secure, private and untraceable transactions.

As a result, most of the features of Monero extend to the Haven protocol, including the bulletproofs and other privacy tech. The base currency of Haven is the XHV, which is burnt to provide users with private, untraceable, synthetic assets and commodities called xAssets.

The network uses a “mint and burn” process to provide users with untraceable digital assets with standard market pricing and real asset-pegged value storage. Simply, users can burn Haven (XHV) for Haven Dollars (xUSD), which is a synthetic stablecoin.

Kleros (PNK) is a decentralized dispute resolution project that launched in July 2018. It is an open-source online dispute resolution protocol that uses blockchain and crowdsourcing to adjudicate disputes fairly.

Kleros offers a middleman service for decentralized applications (DApps) and their users. If the service provided by the application does not create a dispute, Kleros acts as a trustless third-party service for payment.

When a dispute does occur, however, each party can apply for arbitration through the Kleros arbitrators that are selected from the owners of PNK tokens. PNK is an Ethereum-based ERC-20 utility token with a fixed supply.

At this point, the jurors can make a decision that will favor either party. The arbitration fees are distributed to all arbitrators in the form of ETH; jurors who have issued a minority decision lose part of their PNK tokens for the benefit of the majority of jurors. This decision can be appealed, at a cost. The stated mission of Kleros is to offer easier access to justice and improve individual freedom.

Kleros charges a cost that is payable in ETH and is provided by the parties to the dispute or drawn from the funds previously locked in escrow.

Fei protocol is a DeFi native algorithmic stablecoin. The aim of Fei is to propose a technological solution in a sweet spot between rigid overcollateralized decentralized stablecoin and centralised custodial stablecoins.

Fei Protocol runs on two crypto assets: FEI stablecoin and TRIBE governance token.

FEI is aimed to be a more capital efficient and fully decentralized stablecoin. The protocol uses the value it controls to maintain liquid secondary markets and earn yield for the protocol.

The project was founded in December 2020 and immediately attracted significant interest in the crypto community. It resulted in $19 million VC investment in early March 2021. Among the names that have entered this project are Andreessen Horowitz (a16z), Coinbase Ventures, Nascent and Framework Ventures.

There were some issues with the peg in the original mechanism, but through a series of governance upgrades the protocol recovered in the months following launch.

Fei v2 intends to be a major upgrade for the system and will launch in late 2021. It features 1:1 redeemability for FEI against protocol reserves, TRIBE buybacks and backstop, and algorithmic protocol controlled value management.

sUSD is a synthetic USD token enabled by the Synthetix protocol. It tracks the price of the US Dollar through price feeds supplied by Chainlink’s decentralized network of oracles. sUSD is integrated across the DeFi ecosystem as one of the most liquid decentralized stablecoins, including at Curve. It can be traded without slippage for other assets native to the Synthetix protocol at Kwenta or Synthetix.Exchange.

xDai is a cryptocurrency that is pegged to the US dollar. The xDai chain is a stable payment blockchain that is designed for fast and inexpensive transactions. STAKE is secured by proof-of-stake consensus. xDai was founded on Oct. 1, 2018.

STAKE is a multi-chain staking token that is designed to secure the payment layer. Staking allows validators and delegators to provide transaction consensus and receive staking incentives for block production. It is only required for consensus providers, not everyday on-chain transactions.

xDai was created by the POA Network, an open-source public side-chain of Ethereum founded in April 2017. It offers a framework for smart contracts which provides developers with an easy and effective way to code on Ethereum, while also leveraging the POA Network capabilities.

Wrapped NXM (wNXM) is a 1-to-1 backed token that can only be generated by wrapping genuine NXM.

NXM can only be traded among Nexus Mutual members, while wNXM is fully tradable but can't be used at all within the Nexus Mutual protocol.

Bifrost is a multichain middleware platform that enables developers to create Decentralized Applications (DApps) on top of multiple protocols. Not restrained to a single blockchain, Bifrost creates a new environment where developers can combine the best protocols to develop substantially more scalable and flexible DApps.

With Bifrost, developers can write smart contracts for multiple blockchain protocols in an unified environment. They simply select the target blockchain for each part of the code, then Bifrost will transpile, compile, and deploy the code into the target blockchains at once. Developers can also easily operate their DApps and even switch the target blockchain as new and better protocols become available.

Bifrost has multiple components that allow for a seamless connection among all blockchains:

Recipe: A language application that defines the programming language of Bifrost and generates smart contract codes with guaranteed code-level flexibility.

Linker: A system that connects the user and Bifrost components, ensuring the seamless operation on top of multiple blockchains.

Builder: An Integrated Development Environment (IDE) that offers a customized environment to use the comprehensive suite of features of Bifrost.

Gourmet: An automated testing environment for Bifrost service and smart contract development, updating with the latest technologies for blockchain.

Scan: A dashboard that provides you with a full view of the internal process of Bifrost and shows your blockchain interconnectivity in diagram.

Peercoin, also known as PPC or Peer-to-Peer Coin, was created by Sunny King and his team and launched in August 2012. It is the first blockchain to implement Proof-of-Stake consensus.

The primary inspiration behind the creation of Peercoin was to address a number of perceived shortcomings of Bitcoin, including energy efficiency, security and sustainability, decentralization and long-term viability.

Essentially it was designed as an enhanced replacement for Bitcoin. As such, it was originally forked from Bitcoin and uses the same UTXO style blockchain. However, Peercoin's code was modified to introduce Proof-of-Stake as its primary consensus protocol. The next section explains how this makes for a better blockchain.

Given that Peercoin uses most of the same code, it can easily port new features from Bitcoin and utilize any of the supporting infrastructure, including tech advancements like Taproot or Lightning Network. Peercoin is the only Proof-of-Stake blockchain that uses modern Bitcoin code, making it the perfect drop-in replacement.

Peercoin also has a dedicated community, is actively developed, fairly distributed, has low barriers of participation, can do everything that Bitcoin does, minus the 13 TWh of energy usage, and it's not a scam.
