Abelian is a Layer 1 Blockchain system which is quantum resistant and privacy preserving. By quantum resistant, Abelian’s cryptographic systems can defend against attacks launched by the future powerful quantum computers. By privacy preserving, Abelian has the privacy coin ABEL, which can be used with full privacy, privacy with accountability, or privacy in the pseudonymous level.

This is the world’s first Blockchain system which is both post-quantum and privacy-preserving. In addition, the security and privacy assurance of Abelian are both mathematically proven secure. This is also the world’s first provably secure Blockchain system with its security and privacy being both mathematically reduced to some well-known quantum-resistant hard problems.

Abelian’s lattice-based post-quantum cryptosystems are based on CRYSTALS-Dilithium and Kyber, both have been chosen by the US National Institute of Standards and Technology (NIST) as in the first batch of post-quantum cryptographic (PQcrypto) national standards. This symbolizes the mass adoption of these PQcrypto primitives by the federal agencies and the rest of the world for replacing existing elliptic curve cryptosystems.

Abelian makes use of linkable ring signatures in the context of post-quantum security. While different from Monero, Abelian has multiple levels of privacy spanning from pseudonymity to full privacy. Pseudonymity gives similar anonymity assurance to that by Bitcoin. Full privacy protects sender and receiver wallet addresses, and also the transaction amount. In between pseudonymity and full privacy, Abelian also supports accountability, which lets a user share a trapdoor information with a third party in such a way that full privacy is still ensured against the public while it becomes pseudonymous to this third party.

Abelian’s Proof-of-Work (POW) mechanism is compatible with that of the Ethereum 1.0 and hence is GPU friendly. Mining rigs and farms which were previously built for Ethereum 1.0 mining can readily be migrated to mine Abelian privacy coin ABEL.

Abelian is also an ecosystem that in addition to the Layer 1 POW post-quantum Blockchain network, Abelian aims at supporting other Blockchain systems including major EVM-equivalent Blockchains to be quantum-safe. By applying Abelian’s lattice-based zero-knowledge proof systems, Abelian is able to protect digital assets residing on other non-quantum-safe Blockchains against quantum attacks.

Kaspa is a proof-of-work (PoW) cryptocurrency which implements the GHOSTDAG protocol. Unlike traditional blockchains, GHOSTDAG does not orphan blocks created in parallel, rather allows them to coexist and orders them in consensus. The Kaspa blockchain is actually a blockDAG. This generalization of Nakamoto consensus allows for secure operation while maintaining very high block rates (currently one block per second, aiming for 10/sec, dreaming of 100/sec) and minuscule confirmation times dominated by internet latency.

The Kaspa implementation includes a lot of cool features such as Reachability to query the DAG's topology, Block data pruning (with near-future plans for block header pruning), SPV proofs, and later subnetwork support which will make future implementation of layer 2 solutions much easier.

Web3's Decentralised Commerce Layer.
Sell physical things as redeemable NFTs, everywhere, online, in-game and in-verse.
We have solved the hard tech problems of tokenizing and twinning physical items, so you can focus on creating innovative Web3 commerce experiences for your customers.
Our no-code, low-cost tools make it easy to tokenize and sell physical products as NFTs everywhere, including your own Web3 store, the Metaverse, or on NFT marketplaces.
Redemption can be integrated into your own website, giving your brand full control of the customer experience.
With Boson, you can create phygital assets and token-gate purchases, allowing you to effortlessly develop engaging and rewarding digi-physical commerce experiences.
Buyers can redeem the NFT for the physical with the assurance that either they will receive the item or their money back- all without the need to trust intermediaries or sellers, just code and independent dispute resolvers.  Alternatively, Buyers can transfer, gift, trade or hold the NFT - just like any other NFT.
Boson is a groundbreaking technology recognized as a Technology Pioneer by the World Economic Forum. As a decentralized protocol, Boson is built for the benefit of and governed by its users. Consequently, Boson only charges a minimal 0.5% per transaction protocol fee.

Centrifuge is a decentralized asset financing protocol. It connects decentralized finance (DeFi) with real-world assets (RWA) while trying to lower the cost of capital for small and mid-size enterprises (SMEs) and provide investors with a stable source of income. The main goal of the project is to generate profits that are not tied to volatile crypto assets; the developers are pursuing the task of transferring real monetary value from fiat to cryptocurrencies.

Companies are using Centrifuge to access the liquidity that DeFi has to offer. They can tokenize real assets and use these tokens as collateral to access financing through Tinlake, a decentralized application (DApp) lending protocol. The Centrifuge blockchain is built on Polkadot (DOT) for speed and low fees, while its financial DApp Tinlake is built to access Ethereum (ETH) liquidity.

Centrifuge provides liquidity to everyone and investors receive income and rewards in the form of CFG tokens. Centrifuge links assets such as invoices, real estate and royalties with decentralized finance (DeFi). Additionally, borrowers benefit from the fact that they can finance their real assets without banks or other intermediaries.

Flux is the cryptocurrency that powers the Flux ecosystem. It has a number of uses including purchasing resources, collateralizing nodes and fuelling transactions on FluxOS, as well as rewarding both miners and FluxNode operators for providing computational resources.

The Flux ecosystem is devoted to empowering everyone to develop, deploy and use the decentralized Internet of the future: Web3

At this moment the Flux ecosystem consists of: a native, minable POW cryptocurrency ($FLUX), a powerful decentralized computational Flux Network (FluxNodes), a Linux based operating system (FluxOS), the premier digital asset platform (Zelcore) and, finally, the Flux blockchain for on-chain governance, economics and parallel assets to provide interoperability with other blockchains and DeFi access.

Currently (2023/1) Flux has a computational network consisting of around 15,000 decentralized nodes, distributed globally with more than 108,000 CPU cores, 288 terabytes of RAM and 6.7 petabytes of storage. That makes Flux the largest decentralized network in the world!

Metis is an Ethereum Layer-2 scaling solution aiming to solve the blockchain trilemma: that blockchains cannot be decentralized, secure, and scalable simultaneously. It also strives to solve Ethereum's biggest challenges: speed, cost and scalability.

Metis wants to help developers create and manage existing decentralized applications (dApps), while also supporting developers and entrepreneurs who want to build and launch new dApps. It also integrates the Decentralized Autonomous Company (DAC) framework into its Layer 2 infrastructure to help developers and businesses move from Web 2.0 to Web 3.0.

Conflux (CFX) is a public layer-1 blockchain that was made to power decentralized applications (dApps), e-commerce, and Web 3.0 infrastructure by being more scalable, decentralized, and secure than existing protocols.

Conflux makes it easier to transfer valuable assets by making the process quick, effective, free of network congestion, and with low transaction costs. The platform is based on the Tree-Graph consensus mechanism, and it combines Proof-of-Work (PoW) and Proof-of-Stake (PoS) algorithms to achieve consensus. The protocol uses Turing-complete smart contracts written in Solidity, just like those on  Ethereum, and is compatible with the EVM (Ethereum Virtual Machine).

Conflux's growth is fueled by CFX, the platform's native token, which gives users financial incentives to participate and engage more. The token is used to pay transaction fees, govern the network, and is given as compensation to miners who help secure the network via staking.
