The Quantum Resistant Ledger (QRL) is a 'fully quantum resistant blockchain network, using PQ-CRYPTO recommended/IETF standardized cryptography'. The QRL utilizes a hash-based eXtended Merkle Tree Signature Scheme (XMSS) instead of ECDSA, which is reportedly vulnerable to quantum attacks and found in many other blockchain projects. The project claims that the security of its platform is complemented by a suite of applications and a development ecosystem which allows users to 'easily build blockchain applications on its provably quantum resistant network'.

Mysterium Network is an open-source ecosystem of protocols, tools, and Web3 infrastructure making the internet borderless and accessible for all. The network gives both users and builders the tools they need to safeguard their online anonymity and equal access to information. Mysterium held a token sale through which it raised $14 million CHF.

Mysterium is powered by its permissionless, peer-to-peer network. Anyone can turn their device into a node and rent their spare internet resources, such as bandwidth or IP address, in exchange for cryptocurrency. The network is tamper-proof, anonymous, and encrypted like Tor, but with superior usability, stability and speed.

Mysterium’s B2B Network-as-a-Service lays the groundwork for all kinds of enterprise-level services to be built, including the project's flagship product, the Mysterium VPN, available for Android, Windows, Mac and Linux (iOS in 2022). Developers and entrepreneurs can build private, censorship-resistant tools, and businesses can make their products globally accessible and secure. The technology is fully compatible with both Web2 and Web3 platforms and can be integrated with VPNs, proxy services, DeFi wallets, browsers, search engines, data scraping solutions, and streaming apps, building censorship-resistance into the apps we already use.

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.

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.

Orbs is a publicblockchain infrastructure that combines scalability, low fees, performance, security, and ease of use.

The platform is designed for mass-use applications and supports a complete blockchain stack. The Orbs platform is a decentralized, open and transparent network that offers practical blockchain solutions for enterprises and other large-scale consumer applications.

The Orbs protocol uses the ORBS token, which calculates commissions for executed applications and provides an incentive system that is used to select validators, thereby ensuring the integrity of the network. The ORBS token serves as the only means of payment on the Orbs platform.

Orbs was established in 2017 and was developed by experienced engineers, businessmen and scientists who have managed to create an infrastructure that uses blockchain virtualization and randomized proof-of-stake (RPoS) to ensure blockchainscalability.

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.
