Moonbeam is an Ethereum-compatible smart contract parachain on Polkadot. Moonbeam makes it easy to use popular Ethereum developer tools to build or redeploy Solidity projects in a Substrate-based environment.

Moonbeam is much more than just an EVM implementation: it’s a highly specialized parachain that mirrors Ethereum’s Web3 RPC, accounts, keys, subscriptions, logs, and more. The Moonbeam platform extends the base Ethereum feature set with additional features such as on-chain governance, staking, and cross-chain integrations.

Moonbeam’s Ethereum compatibility is unmatched:

Minimal Changes: developers can use existing Solidity smart contracts right away, with no need to rewrite or reconfigure

Use Existing Developer Tools: connect popular tools like MetaMask, Hardhat, Waffle, Remix, and Truffle via a complete set of Web3 RPC endpoints. Use well-known Javascript libraries such as Web3.Js or Ethers.Js.

Unified Accounts, Addresses, and Signatures: use your existing Ethereum H160 accounts & ECDSA signatures to interact with Moonbeam

Tap into the Most Integrations on Polkadot: use existing oracles, bridges, wallets, and other tools that are already building on Moonbeam

Moonbeam provides integration and connectivity between Polkadot Parachains as well as with other chains such as Ethereum and Bitcoin via bridges. Moonbeam was started in 2019 by Derek Yoo of Pure Stake.

Immutable positions itself as the first layer-two scaling solution for NFTs on Ethereum. According to Immutable, its blockchain does away with Ethereum’s limitations like low scalability, a poor user experience, illiquidity, and a slow developer experience. Instead, users benefit from instant trading and massive scalability while enjoying zero gas fees for minting and trading NFTs without compromising user or asset security.

Thanks to this technology, users will be able to create and distribute assets like ERC-20 and ERC-721 tokens on a massive scale. Chris Clay, the game Director of Gods Unchained, a project already building on Immutable, stated that Immutable allows Gods Unchained to implement a new meta-system that was previously impossible. In this fashion, Immutable aims to create a world-class experience for users and developers alike.

Optimism (OP) is a layer-two blockchain on top of Ethereum. Optimism benefits from the security of the Ethereum mainnet and helps scale the Ethereum ecosystem by using optimistic rollups. That means transactions are trustlessly recorded on Optimism but ultimately secured on Ethereum.

Optimism is one of the biggest scaling solutions for Ethereum with over $500 million in TVL. It is home to 97 protocols, the biggest being Synthetix (SNX), a derivatives exchange, Uniswap (UNI), a DEX, and Velodrome (VELO), an AMM. Users can begin their journey on Optimism by adding the chain on their Metamask and bridging tokens like ETH to the L2. On May 31, 2022, Optimism conducted a highly anticipated airdrop of its OP token.

Aptos is a Layer 1 Proof-of-Stake (PoS) blockchain that employs a novel smart contract programming language called Move, a Rust-based programming language that was independently developed by Meta (formerly Facebook)’s Diem blockchain engineers.

Aptos’s vision is a blockchain that brings mainstream adoption to web3 and empowers an ecosystem of DApps to solve real-world user problems.

The PoS blockchain can achieve a theoretical transaction throughput of over 150,000 transactions per second (tps) through parallel execution.

In March 2022, Aptos raised $200 million in a seed round led by the venture capital firm Andreessen Horowitz (a16z). Other crypto heavyweights like Tiger Global and Multicoin Capital took part in the funding round. Fast forward to July, the startup raised another $200 million in a Series A round with participation from Dragonfly, Apollo Global, Franklin Templeton, Animoca, Jump Crypto and others.

Two months later, Binance Labs made a strategic investment of an undisclosed amount in Aptos.

On Oct. 18, 2022, Aptos announced the mainnet launch, while the Aptos genesis occurred on Oct. 12, 2022.

Arbitrum is an Ethereum layer-two (L2) scaling solution. It uses optimistic rollups to achieve its goal of improving speed, scalability and cost-efficiency on Ethereum. Arbitrum benefits from the security and compatibility of Ethereum. Another benefit is the higher throughput and lower fees compared to Ethereum. That is made possible thanks to moving most of the computation and storage load off-chain.

Arbitrum’s native token is called ARB and is used for governance. Offchain Labs, the developers behind Arbitrum, announced the shift to a decentralized autonomous organization (DAO) structure — the Arbitrum DAO. ARB holders can vote on proposals that affect the features, protocol upgrades, funds allocation and election of a Security Council.

Arbitrum has an ambitious roadmap for 2023, which includes: Launching its own layer-three solution called Orbit; Enabling developers to deploy programs written in popular programming languages like Rust, C++, and more using Stylus; Expanding its validator set to include more independent institutional validators; Moving its protocol to layer two with Arbitrum One.

On March 16, 2023,  Arbitrum announced their highly anticipated airdrop of ARB. The token will be airdropped to early users and DAOs building on Arbitrum, with 12.75% of the total supply to be distributed. Recipients were rewarded on a point-based system depending on their interaction with the Arbitrum network until a cutoff date of March 1, 2023. The token generation event is on March 23, 2023.

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.

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.

Osmosis (OSMO) is a decentralized exchange (DEX) for Cosmos, an ecosystem of sovereign, interoperable blockchains all connected trustlessly over IBC, the Inter-Blockchain Communication Protocol. Osmosis also offers non-IBC assets bridged from the Ethereum and Polkadot ecosystems. Originally based on Balancer-style pools, Osmosis is moving to a more sustainable concentrated liquidity model that provides a superior trading and liquidity provision experience.

As an appchain DEX, Osmosis has greater control over the full blockchain stack than DEXs that must follow the code of a parent chain. This fine-grained control has enabled, for example, the development of Superfluid Staking, an improvement to Proof-of-Stake security. Superfluid staking allows the underlying OSMO in an LP position to add to chain security and earn staking rewards for doing so. The customizability of appchains also allows for the development of a transaction mempool shielded with threshold encryption, which will greatly reduce harmful MEV on Osmosis.

Osmosis's vision is to build a cross-chain native DEX and trading suite that connects all chains over IBC, including Ethereum and Bitcoin. To build out the trading functionalities, Osmosis has invited external developers to create a bespoke DEX ecosystem that includes lending, credit, margin, fiat on-ramps, Defi strategy vaults, NFTs, stablecoins, and more – all the functionalities of a centralized exchange and more, plus the trust-minimization of decentralized finance.

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.

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.
