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.

Harmony is a blockchain platform designed to facilitate the creation and use of decentralized applications (DApps). The network aims to innovate the way decentralized applications work by focusing on random state sharding, which allows creating blocks in seconds.

According to the project’s website, Harmony is expected to introduce cross-shard contracts and a cross-chain infrastructure by the end of 2021.

Harmony

Secret (SCRT) is a privacy-oriented blockchain built on Cosmos. Its smart contracts are called Secret Contracts and allow DApps to use private data on Secret, similar to how smart contracts operate on other blockchains. However, Secret Contracts transfer encrypted inputs into encrypted outputs without exposing data. This is made possible thanks to the encrypted contract states during the execution.

Data privacy is guaranteed by combining encryption protocols and key management within a Trusted Execution Environment (TEE). This allows Secret Contracts to compete for several privacy-related use cases that traditional blockchains have found difficult to accommodate. For instance, private voting mechanisms or credit scoring applications become possible since they do not expose sensitive user data on-chain with Secret.

Secret

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.

Nervos Network (CKB) is an open-source public blockchain ecosystem. Its goal is to create a peer-to-peer (P2P) crypto-economy network where users can access a wide range of provably secure blockchain services and capabilities.

The Nervos mainnet launched in November 2019 with a novel dual-layer architecture. There’s a base layer where the consensus mechanism operates and smart assets are stored, and a computation layer where transactions are processed.

The base layer, also known as the Common Knowledge Base, has its own cryptocurrency called CKByte (CKB). It uses the Proof-of-Work (PoW) consensus mechanism and drives the Nervos ecosystem. It is used to pay miners for keeping the network safe, managing network resources, and letting users store things on the network.

The Nervos Network allows developers to create decentralized applications (dApps) that can operate on various blockchain systems. Any of the network layers can be used to run both decentralized apps and smart contracts.

Self-described as "Polkadot's wild cousin," Kusama is an experimental blockchain platform that is designed to provide a massively interoperable and scalable framework for developers.

Kusama is built on Substrate — a blockchain building kit developed by Parity Technologies. Kusama has almost the same codebase as Polkadot — one of the most successful interoperable blockchains.

By deploying on Kusama, fast-paced projects gain access to a highly scalable, interoperable sharded network, with features that are not yet available on Polkadot. To that end, Kusama describes itself as a “canary network.”

The platform is designed to provide a testbed for developers looking to innovate and deploy their own blockchain and can be used as a preparatory network before launching on Polkadot — though many projects opt to stick with Kusama for their final product.

Kusama benefits from a low barrier to entry for deploying parachains, low bond requirements for validators, and is most commonly used by early-stage startups and for experimentation.

Audius is a decentralized music streaming protocol initially built on POA network, but now living on Solana. Audius was launched to remedy the inefficiencies of the music industry, which is plagued by intransparent music rights ownership and intermediaries standing between artists and their audience.

Audius aims to align the interests of artists, fans, and node operators through its platform powered by its native AUDIO token. Artists can upload music, stored and distributed by content and discovery nodes, that fans can listen to for free. Currently, Audius rewards content creators through rewards like featuring in the weekly trending lists. In the future, it plans to integrate stablecoins for artists to offer paid content, as well as artist tokens that give fans the ability to access exclusive content, potentially cooperating with platforms like Rally.

Fantom is a directed acyclic graph (DAG) smart contract platform providing decentralized finance (DeFi) services to developers using its own bespoke consensus algorithm.

Together with its in-house token FTM, Fantom aims to solve problems associated with smart-contract platforms, specifically transaction speed, which developers say they have reduced to under two seconds.

The Fantom Foundation, which oversees the Fantom product offering, was originally created in 2018, with the launch of OPERA, Fantom’s mainnet, coming in December 2019.

Fantom is an open-source decentralized smart contract platform for DApps and digital assets that was created as an alternative to Ethereum. Fantom has the goal of overcoming the limitations of previous generation blockchains and balancing three components: scalability, security and decentralization. The project offers a set of tools to simplify the process of integrating existing DApps, as well as a detailed staking reward system and built-in DeFi instruments.

Fantom is a Layer-1 blockchain that uses a scratch-built consensus mechanism and independent consensus layer, Lachesis, to facilitate DeFi and related services on the basis of smart contracts. Lachesis provides security for other layers as well, including Opera, Fantom's EVM-compatible smart contract chain. The long-playing mission of the project is to “grant compatibility between all transaction bodies around the world.”

One of Fantom's key strengths is its performance and efficient transaction processing, namely thousands of transactions per second, where transactions are settled in 1-2 seconds, and the cost is fractions of a cent per transaction. As a result, Fantom provides higher scalability but at a lower cost.

The ecosystem is based on two main technologies: Lachesis protocol and Opera.

The Lachesis protocol is the core consensus layer that secures the Fantom network by providing both transaction speed and security.

Lachesis is an aBFT consensus engine that uses a directed acyclic graph (DAG) algorithm. How it works: network data can be processed at different times, and the network filters the participants, allowing only one third, which are allocated due to erroneous or malicious behavior, without compromising network processes.

Fantom's Asynchronous Byzantine Fault Tolerant (aBFT) Proof-of-Stake (PoS) consensus mechanism maintains the efficiency of the entire network, its design provides security at maximum speed. Fantom developers emphasize that the PoS mechanism is a leaderless phenomenon — there are no leaders of blocks and participants, and anyone can join (or leave) the network of nodes at a convenient moment.

The key qualities of Lachesis are: asynchronous, leaderless, Byzantine fault-tolerant, and near-instant finality.

As for Opera, it's an application development layer or Fantom's mainnet deployment platform, permissionless and open-source hosting DApps. Thanks to EVM integration and support for the Solidity programming language, Fantom has a full set of smart contract capabilities, which allows users to seamlessly interact with Ethereum platforms while maintaining the advantage of Fantom's transaction efficiency.

The Fantom Foundation concluded that removing block leaders improves network security, so Opera uses a PoS model and leaderless validators (validators do not determine which blocks are valid).

In addition to being a fast, secure and cheap payment platform that enables to make fast and secure payments at minimal cost, Fantom also features on-chain governance where users vote with FTM tokens (one token equals one vote). Of the features: users have the right to express the degree of agreement / disagreement on a scale from 0 to 4.

FTM is the native utility in-house PoS token of Fantom that powers the ecosystem and is applied for payments, network fees, staking, and governance. FTM forms the backbone of transactions, and allows fee collection and staking activities, along with the user rewards the latter represents.

In a nutshell, Cosmos bills itself as a project that solves some of the “hardest problems” facing the blockchain industry. It aims to offer an antidote to “slow, expensive, unscalable and environmentally harmful” proof-of-work protocols, like those used by Bitcoin, by offering an ecosystem of connected blockchains.

The project’s other goals include making blockchain technology less complex and difficult for developers thanks to a modular framework that demystifies decentralized apps. Last but not least, an Interblockchain Communication protocol makes it easier for blockchain networks to communicate with each other — preventing fragmentation in the industry.

Cosmos’ origins can be dated back to 2014, when Tendermint, a core contributor to the network, was founded. In 2016, a white paper for Cosmos was published — and a token sale was held the following year. ATOM tokens are earned through a hybrid proof-of-stake algorithm, and they help to keep the Cosmos Hub, the project’s flagship blockchain, secure. This cryptocurrency also has a role in the network’s governance.

Ethereum Classic (ETC) is the original Ethereum (ETH) blockchain that launched in July 2015. Its main function is as a smart contract network, with the ability to host and support decentralized applications (DApps). Its native token is ETC.

Since its launch, Ethereum Classic has sought to differentiate itself from Ethereum, with the two networks’ technical roadmap diverging further and further from each other with time.

Ethereum Classic first set out to preserve the integrity of the existing Ethereum blockchain after a major hacking event led to the theft of 3.6 million ETH.

Cardano is a proof-of-stake blockchain platform that says its goal is to allow “changemakers, innovators and visionaries” to bring about positive global change.

To learn more about this project, check out our deep dive of Cardano.

The open-source project also aims to “redistribute power from unaccountable structures to the margins to individuals” — helping to create a society that is more secure, transparent and fair.

Cardano was founded back in 2017, and named after the 16th century Italian polymath Gerolamo Cardano. The native ADA token takes its name from the 19th century mathematician Ada Lovelace, widely regarded as the world’s first computer programmer. The ADA token is designed to ensure that owners can participate in the operation of the network. Because of this, those who hold the cryptocurrency have the right to vote on any proposed changes to the software.

The team behind the layered blockchain say that there have already been some compelling use cases for its technology, which aims to allow decentralized apps and smart contracts to be developed with modularity.

In August 2021, Charles Hoskinson announced the launch of the Alonzo hard fork, causing Cardano price to surge, gaining 116% in the following month. On Sept. 12, 2021, the Cardano ‘Alonzo’ hard fork officially launched, bringing smart contract functionality to the blockchain. Over 100 smart contracts were deployed in the following 24 hours after the launch.

Cardano is used by agricultural companies to track fresh produce from field to fork, while other products built on the platform allow educational credentials to be stored in a tamper-proof way, and retailers to clamp down on counterfeit goods.
