Best Layer 2 Protocols for Polkadot

ChainX, the first project to be launched in the polkadot ecosystem.ChainX is dedicated to the research, application and development of Bitcoin layer 2, digital asset gateway, and Polkadot second layer relay chain. To realize cross-chain asset exchanging, ChainX will be leading the new direction of Bitcoin Cross -DEFi. The key to the digital currency market is Bitcoin, which has a market capitalization of US$1 Trillion. Its value proposition allows for further and deeper blockchain technology breakthroughs. This validates Bitcoin as a payment option and a superior method of transferring and storing values. Many believe we have only seen the tip. ChainX is committed to the research and expansion of Bitcoin's Layer2 financial platform. We strive to increase Bitcoin's value flow and enrich financial derivative opportunities.

Celer Network is a layer-2 scale platform that provides fast, secure, and low-cost applications on Ethereum, Polkadot, and other blockchains for mass adoption. Celer created the first generalized state channel network in the world and continues to push the boundaries of layer2 scaling using advanced Rollup technology. Core applications and middlewares such as cBridge, Layer2.finance, and many more ecosystem applications built on Celer, have attracted larger audiences in DeFi and blockchain interoperability. Layer2.finance addresses the two biggest obstacles to DeFi's mass adoption: the extremely high transaction fees and the difficulty of using and navigating the platform. cBridge, a multi-chain network, allows instant, low-cost, ANY-to-ANY value transfers between and within Ethereum's layer-2 chains. This includes Ethereum main chain, as well as other layer-1s and layer-2s.

Blockchain-powered smart contracts cannot be accessed from the internet and are therefore isolated from the rest of the world. The smart contract's computation is also extremely expensive and limited in resource capacity. A Decentralized Oracle service supporting multiple heterogeneous blockchains. DOS Network provides real-world data, event, and computation power to smart contract in a secure and reliable way that is scalable, efficient, and scalable. Many scenarios, such as flight delay insurance, can be automatically indemnified by DOS Network by bringing externally insured events to the onchain insurance contract. To obtain reliable and verifiable price feeds for stablecoins or crypto derivatives, DOS Network must be used frequently. DOS Network allows crypto lending platforms to easily access token exchange rates, import borrower's social media data, and instantly determine interest rates.

Astar Network is a Web3.0-compatible, scalable infrastructure. Astar Network was built with Parity’s Substrate framework. It can also be a future Polkadot Parachain that acts as a scalable smart contracts platform. Smart contracts are not supported by the Polkadot Relaychain. This gives Astar the chance to fill this gap. Scalability is a key requirement for dApp developers. Astar Network allows developers to build any application they want without having to think about its scalability. Astar Network is open-source. There are many opportunities to be involved in our ecosystem. Astar Network is an open source project that anyone can contribute to, develop, or modify. Astar Network's mission it to provide a scalable, interoperable and decentralized application platform that defines the new web, Web3.0.
