Best Layer 2 Protocols for Guarda Wallet

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.

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.

Smart contracts can be built using mainstream software stacks. You can make a leap from Solidity to the vast array of Linux-supported software components. You can achieve a million-fold increase in computational scalability, large file data availability, and low transaction costs. All this while maintaining the strong security guarantees offered by Ethereum. You can keep your DApps private, from games that hide players' data to Enterprise applications that use sensitive data. Descartes performs large computational tasks off-chain on a Linux virtual computer fully specified by smart contracts. The computations are fully verifiable, and can be enforceable on-chain by Descartes node runners. This preserves the strong security guarantees of underlying blockchain. With multimillion-fold computational gains and strong security guarantees, you can overcome the Ethereum scalability limitations.

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.
