Best Layer 2 Protocols for Freelancers

Early internet applications were built on separate networks that required different access and interaction methods. Today, we see this segregation again in a decentralized world with poor interoperability. Nervos Network provides a suite integrated solutions that enable developers to create Universal Apps. You can choose your interface, choose your crypto, and then stick with it. However, you can still access the entire space. Nervos eliminates the frustration of multiple wallets and exchanges as well as seed phrases. Nervos allows you to target any Virtual Machines (VM) and build on it. You can easily port your dApp to other platforms and have instant access to the entire Blockchain ecosystem. Sustainable crypto-economics that includes a built-in store-of-value mechanism to solve the most difficult sustainability problems for public blockchains.

Connext is the most popular protocol for fast, fully custodial transfers and contract calling between EVM-compatible system. Connext is a network that connects liquidity pools on different chains. These pools can be swapped by users, much like AMM DEXes such as Uniswap. Connext routers are the backbone of the network. They provide liquidity for user swaps and earn fees in return. Connext can be used by developers to create seamless crosschain experiences. Simply drop-in our Widget and you can enable crosschain swaps in just five minutes. Integrate with our API at a lower level for even more powerful features, such as crosschain contract calls.

StarkEx generates validity verifications to ensure that only valid data is committed on-chain from computations that have been performed with integrity. StarkEx's huge scaling capabilities are due to the uneven division of computation between the off-chain prover (or on-chain verifier). StarkEx powers self custodial dApps and employs innovative anticensorship mechanisms that ensure that users' funds remain in their custody. StarkEx was designed to meet a wide range of user and application requirements. Applications that want to integrate with StarkEx will arrive on Mainnet in a few weeks, depending on their maturity. State updates can be considered finalized once they have been verified on-chain with validity proofs. This is often quicker than fraud proofs which can take up to a few hours.

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.

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.

DAppChain, TRON's sidechain project, is called DAppChain. DApps can now operate on TRON with lower energy consumption and faster speeds. This will allow for unlimited capacity for TRON’s main network. The sidechain uses the same DPoS consensus as the mainchain. It supports smart contracts, as well as almost all the functions of the mainchain. TRON users can easily adapt the sidechain to their needs. Developers can migrate existing DApps or create new ones on the sidechain. DAppChain is committed providing ecosystem participants with a flexible, well-configured and highly customized network of multiple sideschains. This is another characteristic of each sidechain in DAppChain. Sidechains can consume much less resources than the main chain. The cost of resources consumed on the sidechain is only a fraction that of the mainchain transaction.

Your imagination is limitless when it comes to private money, escrows, money streaming, micropayments and other forms of private money.

A cluster (or constellation) is a group of 5-19 auditor servers and one leading server (alpha). Each party confirms its identity publicly with a Stellar ed25519 publickey. It is important to send public keys to clients with client software so that they can be signed directly on the client's side. Client funds are stored in one Stellar account (vault), which is protected by M-ofN multi-sig. N is the total number independent servers that make up a constellation and M is the majority vote (>50%) plus 1. Any withdrawal operation must have the majority of signatures from all quorum participants. This is guaranteed by the underlying Stellar ledger. Trades and payments with instant confirmation and finality of 5 seconds.
