Founded in 2017, Chainlink is a blockchain abstraction layer that enables universally connected smart contracts. Through a decentralized oracle network, Chainlink allows blockchains to securely interact with external data feeds, events and payment methods, providing the critical off-chain information needed by complex smart contracts to become the dominant form of digital agreement.

The Chainlink Network is driven by a large open-source community of data providers, node operators, smart contract developers, researchers, security auditors and more. The company focuses on ensuring that decentralized participation is guaranteed for all node operators and users looking to contribute to the network.

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

Polygon (previously Matic Network) is the first well-structured, easy-to-use platform for Ethereum scaling and infrastructure development. Its core component is Polygon SDK, a modular, flexible framework that supports building multiple types of applications.

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

Using Polygon, one can create optimistic rollup chains, ZK rollup chains, stand alone chains or any other kind of infra required by the developer.

Polygon effectively transforms Ethereum into a full-fledged multi-chain system (aka Internet of Blockchains). This multi-chain system is akin to other ones such as Polkadot, Cosmos, Avalanche etc. with the advantages of Ethereum’s security, vibrant ecosystem and openness.

The $MATIC token will continue to exist and will play an increasingly important role, securing the system and enabling governance.

Polygon (formerly Matic Network) is a Layer 2 scaling solution backed by Binance and Coinbase. The project seeks to stimulate mass adoption of cryptocurrencies by resolving the problems of scalability on many blockchains.

Polygon combines the Plasma Framework and the proof-of-stake blockchain architecture. The Plasma framework used by Polygon as proposed by the co-founder of Ethereum, Vitalik Buterin, allows for the easy execution of scalable and autonomous smart contracts.

Nothing will change for the existing ecosystem built on the Plasma-POS chain. With Polygon, new features are being built around the existing proven technology to expand the ability to cater to diverse needs from the developer ecosystem. Polygon will continue to develop the core technology so that it can scale to a larger ecosystem.

Polygon boasts of up to 65,000 transactions per second on a single side chain, along with a respectable block confirmation time of less than two seconds. The framework also allows for the creation of globally available decentralized financial applications on a single foundational blockchain.

The Plasma framework gives Polygon the potential of housing an unlimited number of decentralized applications on their infrastructure without experiencing the normal drawbacks common on proof-of-work blockchains. So far, Polygon has attracted more than 50 DApps to its PoS-secured Ethereum sidechain.

MATIC, the native tokens of Polygon, is an ERC-20 token running on the Ethereum blockchain. The tokens are used for payment services on Polygon and as a settlement currency between users who operate within the Polygon ecosystem. The transaction fees on Polygon sidechains are also paid in MATIC tokens.

Founded in 2017 and launched via IEO on Binance in March 2019, Fetch.AI is an artificial intelligence (AI) lab building an open, permissionless, decentralized machine learning network with a crypto economy. Fetch.ai democratizes access to AI technology with a permissionless network upon which anyone can connect and access secure datasets by using autonomous AI to execute tasks that leverage its global network of data. The Fetch.AI model is rooted in  use cases like optimizing DeFi trading services, transportation networks (parking, micromobility), smart energy grids, travel — essentially any complex digital system that relies on large-scale datasets.

Filecoin is a decentralized storage system that aims to “store humanity’s most important information.” The project raised $205 million in an initial coin offering (ICO) in 2017, and initially planned a launch date for mid-2019. However, the launch date for the Filecoin mainnet was pushed back until block 148,888, which is expected in mid-October 2020.

The project was first described back in 2014 as an incentive layer for the Interplanetary File System (IPFS), a peer-to-peer storage network where users pay for data storage and distribution services in $FIL. Filecoin is open protocol and backed by a blockchain that records commitments made by the network’s participants, with transactions made using FIL, the blockchain’s native currency. The blockchain is based on both proof-of-replication and proof-of-spacetime.

Filecoin is open-source and decentralized, which means that all governance is in the hands of the community. On the Filecoin platform, developers have the opportunity to create cloud file storage services like Dropbox or iCloud. Anyone can join Filecoin and start storing their data or earn money by providing space for someone else's funds. The creators of Filecoin opted for their blockchain technology to run the network and their token with their own consensus.

$FIL is the native currency of Filecoin that powers the entire network and all processes. Clients pay for transactions in FIL tokens. Miners place FIL as collateral, guaranteeing their services.

The developers claim that Filecoin solves the problem of inefficient file storage and retrieval. Customers can find the right solution with an efficient set of tools and its core development, IPFS.

Filecoin

Algorand is a self-sustaining, decentralized, blockchain-based network that supports a wide range of applications. These systems are secure, scalable and efficient, all critical properties for effective applications in the real world. Algorand will support computations that require reliable performance guarantees to create new forms of trust.

The Algorand mainnet became live in June 2019, and was able to handle almost 1 million transactions per day as of December 2020. Algorand transaction metrics can be viewed here. Algorand initial coin offering (ICO) was held in June 2019, with the Algorand price of $0.24 per token.

Algorand

Polkadot is an open-source sharded multichain protocol that connects and secures a network of specialized blockchains, facilitating cross-chain transfer of any data or asset types, not just tokens, thereby allowing blockchains to be interoperable with each other. Polkadot was designed to provide a foundation for a decentralized internet of blockchains, also known as Web3.

Polkadot is known as a layer-0 metaprotocol because it underlies and describes a format for a network of layer 1 blockchains known as parachains (parallel chains). As a metaprotocol, Polkadot is also capable of autonomously and forklessly updating its own codebase via on-chain governance according to the will of its token holder community.

Polkadot provides a foundation to support a decentralized web, controlled by its users, and to simplify the creation of new applications, institutions and services.

The Polkadot protocol can connect public and private chains, permissionless networks, oracles and future technologies, allowing these independent blockchains to trustlessly share information and transactions through the Polkadot Relay Chain (explained further down).

Polkadot’s native DOT token serves three clear purposes: staking for operations and security, facilitating network governance, and bonding tokens to  connect parachains .

Polkadot has four core components:

Relay Chain: Polkadot’s “heart,” helping to create consensus, interoperability and shared security across the network of different chains;

Parachains: independent chains that can have their own tokens and be optimized for specific use cases;

Parathreads: similar to parachains but with flexible connectivity based on an economical pay-as-you-go model;

Bridges: allow parachains and parathreads to connect and communicate with external blockchains like Ethereum.

Polkadot

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.

Cosmos

NEAR Protocol is a layer-one blockchain that was designed as a community-run cloud computing platform and that eliminates some of the limitations that have been bogging competing blockchains, such as low transaction speeds, low throughput and poor interoperability. This provides the ideal environment for DApps and creates a developer and user-friendly platform. For instance, NEAR uses human-readable account names, unlike the cryptographic wallet addresses common to Ethereum. NEAR also introduces unique solutions to scaling problems and has its own consensus mechanism called “Doomslug.”

NEAR Protocol is being built by the NEAR Collective, its community that is updating the initial code and releasing updates to the ecosystem. Its declared goal is to build a platform that is “secure enough to manage high value assets like money or identity and performant enough to make them useful for everyday people.”

Flux, a protocol that allows developers to create markets based on assets, commodities, real-world events, and Mintbase, an NFT minting platform are examples of projects being built on NEAR Protocol.

NEAR Protocol

Avalanche is a layer one blockchain that functions as a platform for decentralized applications and custom blockchain networks. It is one of Ethereum’s rivals, aiming to unseat Ethereum as the most popular blockchain for smart contracts. It aims to do so by having a higher transaction output of up to 6,500 transactions per second while not compromising scalability.

This is made possible by Avalanche’s unique architecture. The Avalanche network consists of three individual blockchains: the X-Chain, C-Chain and P-Chain. Each chain has a distinct purpose, which is radically different from the approach Bitcoin and Ethereum use, namely having all nodes validate all transactions. Avalanche blockchains even use different consensus mechanisms based on their use cases.

After its mainnet launch in 2020, Avalanche has worked on developing its own ecosystem of DApps and DeFi. Different Ethereum-based projects such as SushiSwap and TrueUSD have integrated with Avalanche. Furthermore, the platform is constantly working on improving interoperability between its own ecosystem and Ethereum, like through the development of bridges.

Avalanche

VeChainThor (VET) is a versatile enterprise-grade L1 smart contract platform whose origins began in 2015. VeChain is known as a pioneer of real-world enterprise applications, and built a distributed platform powered by Internet of Things (IoT) technologies, NFC chips and blockchain to help various industries solve data-related challenges.

VeChain solves major blockchain adoption hurdles. The platform uses an intelligent two token model, VET and VTHO, separating the protocol's Store of Value and gas fee payment mechanisms, ensuring costs can be kept low and stable. Fee delegation allows smart contracts to pay gas fees on behalf of business users, and an advanced transaction model allows data to be packaged more efficiently while ensuring finality of data.

VeChain is focused on delivering a wave of incentive-based sustainability dApps through its new platform, VeBetterDAO, working closely with Boston Consulting Group to achieve adoption across enterprise and individual users, and helping  onboard the next billion users to Web3 over the coming decade.

From supply chains to sustainability, VeChain has continuously demonstrated its leading role as a driver of blockchain in business, and is dedicated to its role as a pioneer of driving real world adoption of blockchain technology.

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.

Fantom

RenderToken (RNDR) is a distributed GPU rendering network built on top of the Ethereum blockchain, aiming to connect artists and studios in need of GPU compute power with mining partners willing to rent their GPU capabilities out. Conceived in 2009 by OTOY, inc. CEO Jules Urbach and launched in 2017, RNDR held its first public token sale in October of that same year, followed by a private sale period lasting from January 2018 – May 2018, wherein a total of 117,843,239 RNDR were sold at a price of 1 RNDR = $0.25 USD equivalent of token.
During the private sale period, early adopters were onboarded onto the RNDR Beta Testnet, where beta node operators and artists worked collaboratively with the RNDR team in building and testing the network, up until its public launch on April 27th 2020.

SingularityNET is a blockchain-powered platform that allows anybody to easily "create, share, and monetize" AI services, thanks to its globally-accessible AI marketplace.

Through the SingularityNET marketplace, users can browse, test and purchase a huge variety of AI services using the platform’s native utility token — AGIX. Moreover, the marketplace represents an outlet AI developers can use to publish and sell their AI tools, and easily track their performance.

With the benefits of LLMs and generative AI are increasingly exciting, their limitations are also becoming increasingly apparent. The convergence of structured knowledge with neural networks is emerging as the key to overcoming their shortcomings.

Uniquely positioned at the heart of this convergence, SingularityNET will prioritize the integration of Knowledge Graphs (KGs) and comprehensive Neural Symbolic tools for LLMs, with the goal of empowering developers to create the next generation of AI systems on the SingularityNET Platform.

SingularityNET is strategically positioned to become the Knowledge Layer of the Internet, leading the evolution of the emerging AI landscape while also laying the foundations for the Artificial General Intelligence (AGI) of tomorrow.

The team behind SingularityNET pioneered the development of an AI known as Sophia, which is described as the "world's most expressive robot". SingularityNET’s goal is to enable Sophia to be able to fully understand human language, and continue developing “OpenCog” — an AI framework that is hoped to eventually achieve a state known as “advanced general intelligence,” i.e. human-level artificial intelligence (or beyond).

The platform was first announced in 2017 and completed an initial coin offering (ICO) in December the same year, raising $36 million in just one minute.

Decentraland (MANA) defines itself as a virtual reality platform powered by the Ethereum blockchain that allows users to create, experience, and monetize content and applications.

In this virtual world, users purchase plots of land that they can later navigate, build upon and monetize.

Decentraland was launched following a $24 million initial coin offering (ICO) that was conducted in 2017. The virtual world launched its closed beta in 2019 and opened to the public in February 2020. Since then, users have created a wide range of experiences on their parcels of LAND, including interactive games, sprawling 3D scenes and a variety of other interactive experiences.

Decentraland uses two tokens: MANA and LAND. MANA is an ERC-20 token that must be burned to acquire non-fungible ERC-721 LAND tokens. MANA tokens can also be used to pay for a range of avatars, wearables, names, and more on the Decentraland marketplace.

Decentraland (MANA) is a decentralized virtual world platform with software based on the Ethereum blockchain, where users create, test and monetize content. In short: users buy virtual plots of land as NFTs with MANA tokens on the Decentraland platform. Progress in the game depends only on players themselves, their efforts and their imagination.

The digital platform is completely owned by its users. Within the Decentraland metaverse, participants can explore the virtual world, purchase plots of land that can be monetized, create works of art, own non-fungible tokens (NFTs), and take part in a decentralized autonomous organization of the platform Decentraland DAO. Due to the DAO, the community influences the development vector of the project.

In addition, users have access to interactive applications, in-world payments and peer-to-peer communication. The 3D world resonates with many participants as Decentraland has many applications, both entertainment for gamers and business for investors.

Two types of tokens called MANA and LAND govern operations in Decentraland. They also allow users to interact with the platform.

MANA is the official currency of Decentraland. It’s an ERC-20 standard token that powers the Decentraland platform. With MANA, users can purchase plots of LAND, as well as pay for in-game items and services.

MANA gives its holders the right to vote in Decentraland DAO. MANA can be purchased on a cryptocurrency exchange or by selling collectibles on Decentraland Marketplace. The owner of tokens converts them to wrapped MANA, or wMANA, and then commits them to the DAO. One wMANA equals one vote. MANA can be exchanged for fiat currency and other digital assets.

As for LAND, it’s a non-fungible token (NFT) based on Ethereum (ETH). It is used to track ownership of land parcels aka digital real estate. Like MANA, LAND is part of the protocol and confers voting rights, but LAND does not need to be fixed in the DAO. One LAND is equal to two thousand votes.

Players choose what to do with their land. Owners store tokens in crypto wallets and buy necessities with MANA tokens on the Decentraland Marketplace. Moreover, on the marketplace, participants can manage or exchange LAND tokens (priced in MANA). Holders use the marketplace to transact or transfer in-game items. All transactions are conducted, regulated and registered via the Ethereum blockchain.

Decentraland combines an online gaming space and blockchain technology. All control over the rules is given to the players, and token holders vote on in-game and organizational policies. The original goal was to form a decentralized virtual reality, but in practice, Decentraland has turned into a massive NFT market.

A special role in Decentraland is assigned to NFTs, such as collectibles, virtual equipment and real estate (LAND). However, for new players who want to join the universe and seize NFTs, the entry barrier will be high.

The Decentraland protocol is built on three levels using Ethereum smart contracts. On the consensus layer, the ownership of LAND is tracked and managed. The land content layer displays the content of the Decentraland virtual world. Finally, on the real-time layer, participants interact with each other.

The platform was co-founded by two blockchain experts, Ari Meilich and Esteban Ordano, in 2015. Officially it was launched a year later and became available only in February 2020, gradually turning from a 2D experiment into a full-fledged 3D world.

To sum up, Decentraland is a decentralized game and a 3D virtual reality platform where players own lands and create limitlessly. Decentralized Autonomous Organization (DAO) software is at the core, and governance is in the hands of the community. Through the native token MANA, players participate in any proposals for managing and improving the ecosystem, the auction system, and the in-game policy.

Decentraland

Launched in 2011 by Pixowl, The Sandbox is a blockchain-based virtual world allowing users to create, build, buy and sell digital assets in the form of a game. By combining the powers of decentralized autonomous organizations (DAO) and non-fungible tokens (NFTs), the Sandbox creates a decentralized platform for a thriving gaming community.

According to the official whitepaper, the Sandbox platform’s main mission is to introduce blockchain technology in mainstream gaming successfully. The platform focuses on facilitating a creative “play-to-earn” model, which allows users to be both creators and gamers simultaneously. The Sandbox employs the powers of blockchain technology by introducing the SAND utility token, which facilitates transactions on the platform.

Theta Network

Hedera is the most used, sustainable, enterprise-grade public network for the decentralized economy that allows individuals and businesses to create powerful decentralized applications (DApps).

It is designed to be a fairer, more efficient system that eliminates some of the limitations that older blockchain-based platforms face — such as slow performance and instability.

It was funded through an initial coin offering (ICO) in August 2018 and first launched open access to its mainnet just over a year later in September 2019. As part of the ICO, investors were able to purchase the platform’s native utility token (HBAR) at the lowest possible pricing.

The HBAR token has a dual role within the Hedera public network.

First and foremost, HBAR the fuel that powers Hedera services, such as smart contracts, file storage and regular transactions. Second, it's used to help secure the network, since HBAR users can stake their tokens to assist with maintaining the integrity of the platform.

Hedera (HBAR) is the native cryptocurrency of Hedera Hashgraph, a platform that is positioned as an alternative to traditional blockchain technology and aims to excel in speed, efficiency and security.

Older blockchains tend to use a consensus mechanism like proof-of-work (PoW) to validate transactions, while younger blockchains opted for proof-of-stake (PoS). The Hedera Hashgraph system has a structure that was created from scratch particularly for the project. Hedera is based on a PoS model that is believed to increase the efficiency of transaction verification in the network, provide a high level of security, and protect the network from hacker attacks. Its ecosystem has the underlying hashgraph consensus algorithm and the global enterprise governing body.

Hedera Hashgraph is a distributed ledger technology (DLT). According to the project website, Hedera differs from other blockchains because it uses a new consensus algorithm called hashgraph. It intends to process and execute transactions faster, eliminate delays, and smooth out the TPS (transactions per second) indicator. Hashgraph is claimed to be an upgrade in transaction speed, cost, and scalability.

Core network services by Hedera:

Consensus Service (HCS). With HCS, clients send messages to the network to negotiate consensus timestamping and order. In this case, the state is stored offline, and users can define privacy and access control.

Hedera Token Service (HTS). Thanks to HTS, token creation and management are available to customers. It supports built-in tokenization.

The goal of Hedera’s hashgraph is to increase the speed of transactions. Moreover, the network is also focused on high-volume operations: micropayments, data integrity and tokenization.

Like the EVM, the Hedera network maintains a virtual machine that writes smart contracts in the Solidity programming language. On top of that, Hedera offers a set of built-in KYC and AML checks.

From a technical point of view, Hedera is a form of distributed ledger technology. It is a hashgraph, or consensus algorithm, where users agree on the order in which transactions should be performed. However, Hedera is not exactly a blockchain. It has its own distinctiveness and works differently. With hashgraph, all transaction branches are merged, no block equivalent is thrown away, and each is used to reach consensus.

One of the most noticeable features of the network is the Gossip-about-Gossip protocol. According to Dr. Leemon Baird, Hedera's inventor, within the system nodes randomly transmit data about themselves to other nodes via hashgraph using the Gossip protocol. Soon, all nodes in a cluster become familiar with each other. Then a certain data structure is formed. It consists of a payload of transactions, a timestamp, a digital signature, and hashes to the previous structures.

HBAR is Hedera's native token that powers applications on the Hedera network. HBAR is utilized to pay for network services, transaction fees, in-app payments and micropayments. Developers can pay network fees with HBAR tokens, namely: work with smart contracts, file storage and currency exchange. HBAR is used to incentivize and pay network nodes.

Hedera Hashgraph has a decentralized governance system that is set apart. All critical decisions about pricing policy, software updates, and wealth management are made by the Governing Council.

The Internet Computer blockchain incorporates a radical rethink of blockchain design, powered by innovations in cryptography. It provides the first “World Computer” blockchain that can be used to build almost any online system or service, including demanding web social media, without need for traditional IT such as cloud computing services. As such it can enable full end-to-end decentralization.
