Best Layer 2 Protocols for OpenOcean

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.

Polkadot, a blockchain network, is being built to enable Web3.0. This will allow users to control their data and ensure that markets benefit from network efficiency. Gavin Wood, a former co-founder and CTO at Ethereum, founded Polkadot in 2016. Polkadot's technology solves the major problems that have hindered blockchain adoption over the past few years. Parity Technologies created Polkadot's Substrate software development toolkit that allows blockchain developers to create their own custom, fit for use blockchains. Polkadot allows multiple blockchains to communicate with each other, allows for easy upgrades, and introduces "shared Security", a plug and play network security model that allows developers focus on the technology instead of spending time and resources recruiting operators to run a new Blockchain.

Boba is the next-generation Ethereum Layer 2 Optimizmistic Rollup scaling solution. It reduces gas fees, increases transaction throughput, and expands smart contract capabilities. Boba provides fast exits backed with community-driven liquidity pools. This reduces the Optimistic Rollup exit time from seven days to just a few minutes and gives LPs incentive yield farming opportunities. Boba's extensible smart contract will allow developers from all over the Ethereum ecosystem to create dApps that invoke code on web-scale infrastructure like AWS Lambda. This allows them to use algorithms that are too expensive or impossible on-chain. We are building Boba with our users and developers in mind. Our goal is to create a pragmatic L2 which is the first step towards opening Ethereum up to the next billion users. Join us in our mission to grow the community.

Our high-performance Ethereum layer-2 architecture, built on a modular architecture, allows you to build dApps that offer an exceptional user experience, while still relying upon Ethereum's unrivaled level of security. With Ethereum's rollup technology, you can enjoy high throughput and unrivaled safety in a familiar EVM. Mantle Liquidity Staking Protocol is the second core of Mantle ecosystem. Stake ETH to receive yield-bearing Mantle Staked Ether (mETH). As stewards over a significant treasury and with the ability to shape economic outcomes for Mantle products we prioritize a value oriented mindset, transparency and accountability.

Manta Pacific uses Celestia, a modified OP-stack and a modified OP-stack to deliver a cutting edge technical infrastructure that offers extraordinary scalability with low gas fees. Manta Pacific, in conjunction with its universal circuits and ZK applications, provides an unrivaled platform for developing and deploying dApps and ZK apps. Apps deployed on Manta deliver the best user experience and value, from DeFi to gaming to Social. The Manta grants program is designed for users to explore and grow valuable use cases that solve real-world pain points. Manta Network’s zkSBTs enable users to verify without revealing any details in a decentralized, trustless manner. zkSBTs, such as the zkBAB or zkGalxe Passports, provide a seamless KYC verification on-chain without the need to scan passports and enter sensitive personal information.

Scroll was designed by and for Ethereum Developers. Scroll is a fast, reliable, and scalable Layer 2 Blockchain that extends Ethereum capabilities. This allows apps to scale without surprises. Existing Ethereum apps can be migrated to Scroll at a significant cost reduction thanks to bytecode compatibility. Our open-source development approach brings together the best ideas from contributors who share similar values, resulting in more secure and better designed systems. Scroll is a community-driven initiative that redefines and evolves Ethereum's roadmap. Scroll uses advanced EVM models that have been battle-tested, as well as rigorous audits, to ensure our foundation is rooted firmly in security and reliability. Scroll protects its developers and users from vulnerabilities by prioritizing code safety through open source collaboration.

Rootstock is an innovative Bitcoin sidechain which integrates Ethereum compatible smart contract functionality with Bitcoin's robust safety. It is an open-source platform that leverages Bitcoin's consensus mechanism of proof-of-work, achieving more than 60% of Bitcoin's mining power through merged-mining. This integration allows developers the ability to deploy EVM compatible smart contracts, enabling them to create decentralized applications that are secured by Bitcoin's networks. Rootstock's native cryptocurrency, RBTC is pegged 1:1 with Bitcoin. This allows for seamless interaction between DeFi protocols and dApps running on the Rootstock Network, such as minting and swapping, or charging gas fees. The PowPeg Protocol ensures a secure and efficient two way transfer between Bitcoin and Rootstock. This enhances interoperability. Rootstock's ecosystem is comprised of a wide range of applications ranging from swapping, staking and yield optimization on platforms like Sushi, to trading and trading on Oku.

The new scalability stack to Ethereum. Instant transactions and scalable smart contract. Optimism (PBC) is a for-profit corporation that produces a public benefit while also operating in a responsible, sustainable manner. This means that we have to balance the stockholders' interests with the best interests for those who are most affected by our conduct. We also have a "public benefit charter" that we were incorporated with. The Company's specific public benefit purpose is to increase and enshrine fair internet access through the development open-source software. This charter is our promise to the Ethereum community that we will uphold its values and produce infrastructure that promotes the growth of an ecosystem of public good.

zkSync is Ethereum’s most user-centric ZK rollup. ZK rollup does not have an upper limit on the amount it can safely handle in L2. This is unlike any other scaling strategy. All assets can be moved capital-efficiently between ZK rollups and L1. This is in contrast to optimistic rollups. zkSync has the lowest real transaction costs of all planned and existing rollups. zkSync supports meta-transactions and instant confirmations with economic finality. It also offers low-cost privacy and low-cost privacy. zkSync's design is easy and fun. In just a few lines of code, you can integrate payments and atomic swaps. A Rust-based framework allows you to create type-safe and functional-style smart contracts using Zinc. With minimal modifications, deploy your existing EVM codebase.

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.
