Best Layer 2 Protocols for L2BEAT

Loopring is an open protocol that allows you to build scalable, non-custodial Ethereum exchanges. It leverages zero-knowledge proofs, zkRollup, to allow high-performance trading (high throughput and low settlement cost), without compromising Ethereum-level security guarantees. Throughout the trade lifecycle, users always have 100% control over their assets. Loopring allows you to trade on it. Loopring is an open-sourced and audited non-custodial exchange protocol. This means that no one in the Loopring ecosystem has to trust anyone else. With 100% Ethereum-level security guarantees, cryptoassets can be managed by users. Loopring is a highly scalable, decentralized exchange that batch-processes thousands of requests off-chain. This allows for verifiable correct execution via ZKPs. The performance of the underlying blockchains are no longer the bottleneck. Loopring is able to perform most operations, including order matching and trade settlement, using the Ethereum blockchain.

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.

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.

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.
