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'.

High Performance Blockchain is the first permissionless public blockchain to innovate with hardware acceleration and provably random numbers:

acceleration delivers fast, ultra low-fee, on-chain transactions

provably random numbers support 100% fairness

HPB (the coin) is used to pay transaction gas fees and to reward node operators.

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.

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.
