Request for a particular number of blocks with Ettherem transactions: Using UNLOCKTIME
Ethereum provides several parameters in this way the transaction of their procedure, including nlctas, IT transactions. Howver, using the allone 'nloCktiMe', may not note that the transaction will be a certain block.
What istlocktime ‘?
nloCktime is a locking time that prevents the transaction from being online until it fills the certs. This parameter allows for a flexible and pressing transaction time, but also introduces additional intake.
Shoes for a particular block number with nlucktiMe
To wait for a particular block of nloCktime, you need a diversity of syntax:
`strength
Transaction.nlocktime = blocknumber;
`
ReplacementBlocknumberwith the desired block number and make it a valid entire number.
Why is this omitted?
Waiting for specification block #nloCktime can be useful scenarios:
Predictive transaction times using a nloCktime, you can guarantee that transactions are!
Improve Skellity : withnloCCTIMEit becomes in a whipped transaction or concomitant performance of scalability and efficiency.
SUGGESTATION SUBMITTING : By waiting for certain lock time.
Example uses the case
Suppose we want to implement a reward system for consumers who tokens. We need to ensure that all awards are transferred after the number of specifications block (eg 1000). We cannloCktirime 'like this:
strength
Pragma Solidity ^0.8.0;
A prize -winning contract
NAint256 Public Awardic;
mapping (address => nint256) public prizes;
Function of Setrewardvalval
Requires (_rewardyvalval> = 1; / to ensure a positive block number /)
Require (_rewardyrdarlo <= 3600000; / ensure that the reward is valid /)
Awardlorer = _rewardyard;
Iche
Function withdrawal (address user, nint256) mobic {{{
demand (rewards [user]> 0; / Make sure the prizes /)
Requires (block.timestamp> = blocknumber – reward;
// Transfer of rewards to Theer
rewards [user] -= amount;
Iche
Iche
`
In this example, we are a nloctime to wait for the number of specifications block (1000) before we transfer awards. It ensures that all rewards are transmitted after a fixed interval.
Conclusion*
Using a nlocktime` without Ethereum transaction of multiple transactions and can help improve scalabiness, predictions and congestion. However, it is crucial to shape the limitations of the nlocktime “and the user to avoid unexpected behavior or mistakes.
