Fantom transactions are completed in seconds and cost less than a cent. Fantom's validator Nodes form a global, trustless and leaderless Proof of-Stake network. Fantom can process thousands upon thousands of transactions per second and scale up to thousands of nodes. Fantom supports EVM. Fantom allows you to deploy and run your Ethereum dApps. All-in-one DeFi suite. Your wallet allows you to trade, lend, and borrow digital assets. DeFi is available for everyone with almost zero fees and instant transactions

Next generation layer 2 for Ethereum DApps. Scale your dApp with your favorite tools at the lowest possible cost. An aggregator is the same role as a node in Ethereum. Client software can make remote procedure calls (RPCs), to an aggregator using the standard API to interact with an Arbitrum network. The aggregator will then call the EthBridge to produce transaction results to the client just like an Ethereum node. Although it is common for clients to use an aggregator to submit transactions to an Arbitrum Chain, this is not mandatory. There is no limit to the number of aggregators that can exist or who can be an aggregater. In order to improve efficiency, aggregators often combine multiple client transactions into one message that can be submitted to Arbitrum. Arbitrum also supports a privileged Sequencer, which can order transactions and provide low latency transaction receipts.

Ethereum is the community-run technology that powers the cryptocurrency, Ethereum (ETH), and thousands of decentralized apps. Ethereum is a technology that allows for digital money, global payments, as well as applications. The community has created a vibrant digital economy, new ways for creators of online income, and many other benefits. It's accessible to anyone, anywhere in the world. All you need is the internet. Today, billions cannot open bank accounts and others have their payments blocked. The Ethereum decentralized finance system (DeFi), never sleeps nor discriminates. You can send, receive and borrow money anywhere in the world with an internet connection. We can now access 'free' internet services without having to give up our personal data. Ethereum services are available by default. You only need a wallet. These services are free and easy-to-set up. They can be controlled by you and work without your personal information. Stake your ETH to become an Ethereum validator. Staking is a public good for the Ethereum ecosystem. You can help secure the network and earn rewards in the process.

BNB Smart Chain is a blockchain-based platform developed by Binance. It was designed to allow decentralized applications (dApps), and smart contracts. It is a parallel chain that operates alongside Binance Chain. It combines high-speed transactions and the programmability provided by Ethereum-compatible smart contract. BSC uses a Proof-of-Staked-Authority (PoSA) consensus mechanism, which enhances scalability and efficiency while reducing transaction costs. It is compatible with Ethereum Virtual Machine (EVM), which allows developers to easily port projects and dApps from Ethereum. BSC is a popular platform for Decentralized Finance (DeFi), Gaming, and NFT ecosystems. It offers users a fast and low-cost platform for blockchain-based innovation.

Build on Avalanche. You can build without limitations. Avalanche is a platform that allows you to create decentralized financial applications. It is open and programmable. Launch Ethereum dapps to instantly confirm transactions and process thousands of transactions per minute. This is far more than any other decentralized blockchain platform. You can deploy blockchains that meet your application requirements. You can create your own virtual machine and decide how the blockchain should work. Secure the platform by locking up your AVAX and facilitating transactions. Most likely, you have the hardware necessary to join the platform. Avalanche supports Solidity. All your favorite tools, such as Remix, Truffle, or Tenderly, work right out of the box. Avalanche smart contracts are only a tenth as expensive as Ethereum. Low gas fees, front-running, adverse effects, and other negative effects of slow smart contracts blockchains are all gone.

Anchor Protocol allows Terra stablecoin deposits for stable yield. It is powered by block rewards from leading proof-of-stake Blockchains. Terra stablecoins are loved by millions of merchants and users for their instant settlements, low fees, and seamless cross-border trade. Mirror Protocol allows for the creation of fungible assets called "synthetics" that track the prices of real world assets. Mirror synthetics will be used to build smart contracts and bring the world's assets onto the blockchain. You can build smart contracts in Rust or Go, or AssemblyScript. Multiple chains can be used, each connected by the Cosmos IIBC. Use Terra stablecoins, onchain swaps, layer 1 oracles as primitives. Terra's payment services can be accessed by dApp users in a permissive manner. Terra plans to make its stablecoins accessible to every developer on every blockchain. Now available on Ethereum and Solana. More to follow.

Solana is a fast and secure blockchain that can withstand censorship. It provides the open infrastructure necessary for global adoption. Solana is the platform that has been chosen by the best projects in DeFi, Web3 and blockchain gaming to be built on for the long-term. Solana can process 50k transactions every second. We don't think so. To experience Solana's speed, stress test the network. Say goodbye to slow confirmations and high fees. Solana is designed for speed without compromises. Solana uses Proof of History and other innovative innovations to scale the network at Moore's Law speed. Don't worry about fees rising as your user base increases. Solana is designed for applications that have billions of users to keep fees low. Solana's single global status ensures that projects can be connected. Never deal with multiple layers 2 or shards.

The Internet of Blockchains. Cosmos is an expanding ecosystem of interconnected apps, services and apps that are designed for a decentralized future. Discover a new world of connected services. Cosmos apps and services can connect using IBC, an Inter-Blockchain Communication protocol. This innovation allows you to freely exchange data and assets across sovereign decentralized blockchains. The Cosmos Hub serves as the economic heart of Cosmos and provides vital services to the Interchain. The next-generation decentralized exchange will allow you to swap digital assets across the Interchain with very low fees and instant transaction verification. ATOM will soon have the ability to secure many chains with the Interchain Staking feature. In exchange for additional rewards, The Hub's core mission is to connect chains through IBC connections with compatible chains, and operate decentralized bridges with chains such as Ethereum and Bitcoin.

Polygon (previously Matic Network), is a protocol and framework that allows you to build and connect Ethereum-compatible blockchain networks. Although Ethereum is the preferred blockchain development platform, it has its limitations. Polygon - A protocol and framework for building and connecting Ethereum compatible blockchain networks. Preset blockchain networks can be deployed in one click. A growing number of modules are available for the development of custom networks. Interoperability protocol to exchange arbitrary messages with Ethereum or other blockchain networks. Modular and optional security as a service. Modules for adaptors to enable interoperability with existing blockchain networks. Polygon brings together the best of Ethereum, sovereign and other blockchains in an attractive feature set. For developers.
