SERO describes itself as a privacy protection platform for Decentralized Applications. It aims to become a next-generation privacy blockchain that supports smart contract and enables the issuance of privacy coins and anonymous assets. SERO platform reportedly allows developers to issue privacy coins and use them in DApps. 

SERO claims to have built the world's fastest zero-knowledge proof encryption library "Super-ZK" which is reportedly 20+ times faster than the latest zk-SNARKs (Sapling upgrade) that Zcash uses. SERO also claims to be the first privacy coin protocol supporting smart contracts using zero-knowledge proofs.

Firo (FIRO), formerly known as Zcoin, is a cryptocurrency that focuses on being private digital cash. It created the Lelantus privacy protocol which allows users to burn their coins and redeem them later for brand new ones that do not have any transaction history.

Prior to Lelantus, it was also the first cryptocurrency to code and launch a practical implementation of the Zerocoin protocol which became one of the most prevalent privacy protocols in use, prior to it being replaced by Sigma and then Lelantus after cryptographic flaws were discovered in the Zerocoin protocol in 2019.

Nimiq is designed to make cryptocurrencies easy to use for everyone without compromising decentralization. Nimiq is the only blockchain where users always participate directly by default. In comparison to the likes of Bitcoin and Ethereum where the default is to use a third-party node to connect to the network. Learn more: https://youtu.be/dA40oyDVtqs

Team Nimiq invented Nimiq OASIS, the DeFi crypto-fiat bridge! Atomic swaps between crypto like NIM and BTC (ETH coming soon) and fiat currencies like EUR (USD next) with no personal information are now possible. Earned swap fees are converted to NIM and held to create scarcity. See how it works: https://youtu.be/Spp_Be4dHaM

Nimiq created Albatross, a new, super fast Proof-of-Stake consensus algorithm that will launch with Nimiq 2.0, the next version of the Nimiq Blockchain. We expect ~1000 TPS and finality in one second, pushing Nimiq 2.0 to the theoretical limits of single chain blockchain protocols. Energy consumption will also be reduced to less than 1% (compared to current Nimiq POW) with this upgrade. Try out the demo: https://www.nimiq.com/albatross/

Nimiq’s “super-halving” coming soon! The transition to Nimiq 2.0 will reduce the emission rate from currently ~3000 NIM to only ~525 NIM per minute. Calculate your rewards using the Staking Calculator: https://www.nimiq.com/staking-calculator/

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.

ABBC is a blockchain platform that enables secure payment transactions, helping to facilitate retail adoption of cryptocurrencies and make shopping online with digital assets a safer, more enjoyable experience for end-users.

The platform offers three main products: a multi-platform wallet capable of supporting Bitcoin (BTC) and Ethereum (ETH), in addition to a variety of other native cryptocurrencies and ERC-20 tokens; an online shopping application that can be used to shop at over 50 online retailers with cryptocurrencies; and a cryptocurrency exchange platform that offers secure trading and low transaction fees.

The ABBC Coin was created to give holders the ability to govern the development of the ABBC platform by delegating voting power to chosen block producers (BPs) — who are then able to vote on governance proposals. These governance proposals can be on a range of topics but might include launching strategic partnerships, implementing new features or expanding ABBC's services to new regions. Beyond this, ABBC Coins were created as a reward system for online shoppers and can be staked for regular rewards.

ABBC is currently based on the EOSIO blockchain, which enables it to achieve up to 5,000 transactions per second (TPS) while remaining environmentally friendly due to its energy-efficient delegated proof-of-stake (DPoS) consensus mechanism.

ABBC Coin was initially known as Alibabacoin but changed its name in March 2019 following a dispute with Chinese multinational e-commerce giant Alibaba.

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.

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.
