Etheom Laere
As with the nw developer in Ethereum, i s are likes to be anxious to explore the latest scene. One of the most exams is the layer 2 (L2) technologies to the fall of theallowester and mortgage efficient transactions, reducing the congestion probing the translation of the translation of the translation of the translation. In this article, we wit with deed twet of two’s prominent L2 solutions: arbitrator, optimation, optimism and zeksync, focusing on ow to develop in solidity and other programming farming.
What is the solution of layer 2?
The solutions from layer 2 am to increate the scalability and usability of the Etheeum utout safety. Who downloaded some complex logic and calculations from themain chain chain, the seeds can be inimprove transactions, redemption and animprove user’s general experiencing.
Referges: A scalable l will
The referee is one of the most is a popular layer 2 solutions 2 sotions in Ethereum. It is the wag built by a team led by Mihai Alisie, be well – known developer in the Ethereum ecosystem. The referees to provide for rapid and safe transactions while reducing the congestion probed by translational Eetheum.
Development in the refereeing solidity:
- Install the SDK arbitrum : Download the latest version of the SDK archerrum is from the office website.
- Create a new contract : Write your own solidity of contract, which can be employed in the referee’s chain.
- Use the Library: Use the Ethabition of Library to work with Etherateum’s Abi (Binary Application Interface).
- Interact with the referee’s API : Use the referee’s API to catnaments and interact with hysmation.
Example:
`OLIDITY
Pragmas solidity ^0.8.8.0;
Import “ttsps://ontub.com/arbity/solmbarity-ap/master/master/sister/solstery/solstery-apsority of the.sol;
Mycontract contract {
MYFUNCTION FUCTION () PUBI PUBITURNRN (BOOL) {
// Call the arbitrate API to exercise
Uint256 [] Memory entries = New Uint256 [] (1);
unit256 [] memory outputs = Low Uint256 [] (2);
(entries [0], outputs [0]) = abi.encodepacked (1, 2); // Example function call
// Use the API to interact with your agreement
BOOL Result = ABI.DECOBOOL (address (This) .Call.Value
Returns;
}
}
Optimm: a scalable l will
Optimm is the annotherer is popular layer 2 sotion 2 storage provies rapid and safe transactions. It is the torture s to reduce lancy and improve user expertise.
Developing the optimism of solidity:
- Install SDK optimism : Download the latest version of the Optiimm SDK fraction the office website.
- Create a new contract : Write your own solidity of contract, which can be employed in the optimism chain.
- Use the operating : Use the optimism ablectory to work Etheret’s Abi.
- ** Inter Crete thither the Passover, and the resist thereof are oppression.
Example:
`OLIDITY
Pragmas solidity ^0.8.8.0;
Import "tthpps://ontuitive-lab/optimim-lab/solb/solve/blob/sister/sister/sister/sister/solstery/sister.sol”;
Mycontract contract {
MYFUNCTION FUCTION () PUBI PUBITURNRN (BOOL) {
// Call the optimism API to exercise
Uint256 [] Memory entries = New Uint256 [] (1);
unit256 [] memory outputs = Low Uint256 [] (2);
(entries [0], outputs [0]) = abi.encodepacked (1, 2); // Example function call
// Use the API to interact with your agreement
BOOL Result = ABI.DECOBOOL (address (This) .Call.Value
Returns;
}
}
Zksyn: A scalable L2 is only
Zksync is a layer 2 sotions and new consensus with rapidly rapid and safe transactions.
