Launched on Dec 25, 2016, Obyte is a distributed ledger based on directed acyclic graph (DAG). 

It's a post-blockchain technology that achieves true decentralization by getting rid of big power centers and middlemen, such as miners. The team claims that due to the absence of blocks and miners, access to Obyte ledger is decentralized, disintermediated, free (as in freedom), equal, and open.

Obyte claims to be the first DAG-based cryptocurrency platform to support dApps. Due to the absence of miners and blocks, the team claims that there is no risk of front-running and other miner manipulation, and dApps are safer and easier to develop than blockchain-based dApps. DApps are developed in Oscript - a new language that avoids many unsafe programming patterns common in earlier dApp platforms.

Obyte is connected with other popular networks, such as Ethereum, through [Counterstake](https://counterstake.org) -- a truly decentralized cross-chain bridge developed by the Obyte team in 2021.

The team believes that Obyte is especially well suited for DeFi apps. Some notable DeFi apps that exist only on Obyte are:

* [Bonded stablecoins](https://ostable.org): stablecoins based on bonding curves, since 2020.
* [Oswap DEX](https://oswap.io): an AMM DEX with increased APYs for liquidity providers and leveraged trading without liquidations for traders. Since 2020.
* [OSWAP Token](https://token.oswap.io): a governance token for Oswap DEX based on a bonding curve specifically designed for this purpose. Since 2023.
* [Kivach cascading donations](https://kivach.org): a cascading donations platform for helping fund open-source projects on GitHub. Since 2022.
* [Prophet prediction markets](https://prophet.ooo): a prediction markets platform based on bonding curves for trading bets on future events, such as sports and cryptocurrency prices. Since 2022.

Other features include:

* self-sovereign identity, 
* private untraceable currencies, 
* sending crypto to email using textcoins, 
* and extremely small-footprint libraries suitable for small IoT devices.

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.

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.

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

Library Credit (LBRY) is a platform that seeks to simplify the way digital content is distributed and accessed by both consumers and producers.

Library Credit uses a decentralized model to be fair, free, and open to all the involved parties.

More specifically, the platform functions as a distributed network built on top of a protocol that makes it easy for publishers to charge a fee to content consumers without censorship or the need for a middleman.

The project was launched towards the end of 2018 and is now serving an active community.
