Ethereum second layer projects Future Academy

### Optimism

One of the most famous projects of the second layer of Ethereum is Optimism, which has made proposals to reduce the cost and improve the speed of transactions. This platform has provided users with staking conditions using the native SNX token

### Arbitrum

Arbitrum is one of the best Ethereum second layer projects. The project's features help developers cross-compile their own smart contracts. This project does not have its own native token and supports the aggregation of the side chain of transactions and roll up technology.

### Immutable-X

The features of Immutable-X include zero gas fees, instant confirmation of transactions, flawless scalability. It is also one of the first Layer 2 scaling solutions for Ethereum [**NFT**](https://tboursecollege.com/%d8%aa%d9%88%da%a9%d9%86-%d8%ba%db%8c%d8%b1-%d9%82%d8%a7%d8%a8%d9%84-%d9%85%d8%b9%d8%a7%d9%88%d8%b6%d9%87-nft-%da%86%db%8c%d8%b3%d8%aa-%d9%88-%da%86%da%af%d9%88%d9%86%d9%87-%d8%a7%d8%b2-%d8%a2%d9%86/) tokens .

### OMG

OMG is a decentralized automatic market maker exchange. This exchange has the ability to transfer all Ethereum-based tokens to the second layer. The OMG network increases the processing power of Ethereum transactions by more than 1000, and the fee is reduced to about a third of the Ethereum network. Along with the fact that there is no damage or delay in the security of the Ethereum blockchain.

All transactions are settled outside the Ethereum network and Ethereum is only needed for final settlement.

### Polygon

Polygon is designed to develop and connect Ethereum-based blockchain networks and improves the flexibility and security of Ethereum.

In each block of the Polygon chain, it is theoretically possible to process 256 transactions. 7000 transactions per second can be done on Polygan chain; But Ethereum can process less than 15 transactions per second.

### Loopring

Loopring is one of the best Ethereum second layer projects. The native token of this LRC network was developed by the zkRollups team.

With the help of Loopring payment service, you can access all Ethereum-based tokens, send or receive them at a good speed and for free. The processing power of transactions in the Loopring network is about 1000 times that of Ethereum.

### xDai

xDai is an Ethereum-based sidechain. It uses a Proof of Stake (PoS) consensus mechanism and is a stablecoin.

### Scale

Skale works as a decentralized and open source network. It has functional subchain and can process 2000 per second. Skill is 100% compatible with the Ethereum network
