The Validity technology suite has 2 main components: The Validity blockchain and the Validity Smartchain.

The Validity blockchain is a decentralized network that uses a proof of stake (PoS) consensus algorithm. People can stake their VAL coins in the Validity wallet and receive VAL coins as a reward for helping secure the network.

The Validity Smartchain is a second layer built on top of the Validity blockchain. It helps with scaling and provides advanced utilities. VAL is used to pay for these utilities which include: Decentralized Identities (DID), Non Fungible Tokens (NFTs), Social and Reputation Tokens, File Signing and Verification, Decentralized Elections and Voting, etc.

Oxen (formerly known as LOKI) is a privacy tech project with a mission. It’s a private cryptocurrency with instant transactions. An enormous and powerful PoS network. A secure messaging platform. A network anonymity layer. Tools to build a more private future for the Internet — all on blockchain.

Our vision is to provide a range of tools and services powered by the OXEN coin, enabling users and developers all over the world to leverage the power of our decentralised blockchain network to achieve unparalleled privacy and security as they work, play, and live their day-to-day lives on the internet. And this isn’t just an empty vision — we've put in the hard yards and spent years building these technologies to make our vision a reality.

The Oxen privacy stack includes:

Session, a fully anonymous, totally decentralised encrypted messaging platform

Lokinet, a powerful low-latency onion router

Oxen Name System (ONS), a registration system that allows users to provably burn OXEN to purchase temporary or permanent usernames for Session (and Oxen wallets), and domain names for Lokinet services

The Oxen coin is used for:

Staking to run Oxen Service Nodes

Purchasing name registrations for Lokinet (our onion router) and Session (our private messenger)

Transferring value through instant, private transactions with our revolutionary Blink transaction tech

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.

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.

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.
