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.

Elastos, founded in 2017 and building on a vision from 2000, is a blockchain-powered internet version. Its recent breakthrough is the introduction of BeL2, a Layer 2 solution leveraging SmartWeb technology to revolutionize Bitcoin transactions. Elastos is using SmartWeb technology to build the Bitcoin second-layer network BeL2, which extends the efficiency and scalability of the Bitcoin network through smart contracts. This endeavor will enable Bitcoin to power a smart economy and effectively release the liquidity of hundreds of billions of dollars in staked Bitcoin assets.

With over 50% of Bitcoin's hash power protecting it through merged mining, ELA boasts extremely high security and credibility in its network, earning it the esteemed title of "BTC Queen" within the community.

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.

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.

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.

Energi (NRG) is a next generation Proof of Stake (PoS) cryptocurrency. Powered by the Energi blockchain, NRG combines Ethereum smart contract compatibility with a self-funding treasury, decentralized masternode governance, and a Layer 1 and Layer 2 protocol. NRG also serves in place of a governance token for the Energiswap decentralized exchange.
Funded by the NRG treasury, the Energi organization is a blockchain-based financial technology provider. Energi was founded on the goal of delivering secure, decentralized financial solutions. Energi currently employs a team of over 60 contributors spread across 5 continents.

NRG Features
Ethereum-Compatible blockchain with smart contract capabilities to support DApp development.
Funding provided by an economically-optimized, self-funding treasury to enable the upkeep and rapid expansion of the project.
On-Chain Governance driven by a masternode network to guide strategy and provide user protections.
Speed and Scalability delivered by a Layer 1 and Layer 2 network that enables sustainable throughput.

The NRG Economic Model
1 million NRG are released every month and divided between the Energi Treasury, Masternodes, Stakers, and Backbone.
The breakdown of the allocations can be viewed below:
40% to the Energi Treasury
40% to Energi Masternodes
10% to Energi Stakers
10% to the Energi Backbone

TREASURY
Energi’s treasury is self-funded. Funds from the treasury pay for product development, marketing, merchant adoption, and team growth.

MASTERNODES
The primary role of masternodes is to provide stability for the network by validating transactions. Their secondary role is to provide governance by submitting and voting on proposals that dictate the long-term strategy and resource allocation for Energi. Masternode owners are awarded a larger portion of staking rewards as an incentive.

STAKING
Staking enables users to ‘stake’ their NRG on the network; that is, to validate the transactions required to make a new block. Staking creates a simple, easy way for users to take advantage of the Proof of Stake mechanism and get rewarded for doing so.

BACKBONE
Instead of issuing a pre-mine or holding an ICO, Energi’s founder chose to take distributed compensation over time. This ties his financial rewards from the project to Energi’s long-term success and sustainability.

Where Can You Buy NRG?
NRG is available on a number of well-established exchanges. Currently, NRG can be bought, sold, or traded on the following exchanges:

Energiswap
Uniswap
Kucoin
DigiFinex
Bitbns

Who Is the Founder of Energi?
Energi was founded in 2018 by @TommyWorldPower (Twitter) with the goal of being the first cryptocurrency to drive truly global adoption. Tommy has been involved in cryptocurrency since 2012, starting out as an early-adopter and trader.
Through his research as a trader, he identified several key issues that were not being addressed by cryptocurrencies at the time. He created Energi to directly address those issues and provide a sustainable, scalable platform for the future of cryptocurrency.
