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'.

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.

Streamr (DATA) is an open source project and decentralized platform that relies on cryptography instead of trust. It is a P2P, real-time data infrastructure that houses a platform and tools for a new data economy. The technology stack includes a scalable real-time messaging network (pub/sub) hosted on computers worldwide, a marketplace for trading/selling data and a set of tools for working with real-time data.

Streamr (DATA) was crowdfunded in 2017. The main idea is to create decentralized infrastructure and data economy; the mission was formulated by the developers as “Unstoppable Data for Unstoppable Apps.” Streamr tokenizes the value of real-time information and makes it available on their marketplace and data unions. This is built for DApps, IoT devices and more, and they believe this is a crucial protocol for Web 3.0.

The tasks of Streamr DATA coin include creating a comfortable and prosperous information market, which is built on the basis of a data exchange network that is convenient and understandable for users. How it works: the decentralized pub/sub network is supported by nodes around the world, who earn DATA tokens in exchange for the bandwidth and validation they provide.

The competitive advantage lies in the fact that it is an off-chain network (for example, when compared to a similar IOTA service). Therefore, the risk that the project will face scalability and bandwidth issues is modest. The intention of the Streamr team is not to create some special blockchain, but to focus on the development of network optimization technologies. If Streamr lacks the capabilities of Ethereum, developers can always transfer the platform to another blockchain.

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.
