Understanding incredible output groups (UTXOS) in Ethereum
The Ethereum output group (UTXO) is a critical part of its decentralized main book, which allows efficient storage and restoration of outputs that are not in accordance. However, building UTXO can be a complex task, especially for new developers. In this article, we will divide the UTXOS concept and provide guidance on how to implement them effectively.
What are incredible output groups (UTXOS)?
In Ethereum, each block contains more developed outputs that represent transactions that have not yet been spent. These incredible outputs are stored in the Hash set called UTXO. The UTXO set serves as a cache for all incredible outputs, allowing them to recover and reuse quickly.
Why do you need to build a UTXO pool?
Utxo pool building can be beneficial for several reasons:
* Effective storage
: By storing incredible outputs in the hash set, you can avoid duplication of effort and reduce memory use.
* Improved scalability
: UTXES enables effective storage of multiple transactions, reducing the load on the storage layer of the block chain.
* Improved security : Restricting the number of unbelievers, you can better control access to confidential assets.
How to build a UTXO pool
Utxo pool building includes a few steps:
- Initialization of hash set : Create a hash set using an adequate data structure, such as a linked list or table hash.
- Scan Blocking : Itera through each block and extracts the expanded outputs of the hash set.
- Output classification : Order incredible outputs extracted in the descending order according to their hash values.
- Pool maintenance : regularly update the group to eliminate the outdated output hash, which only stores active outputs.
Code Example: Build a UTXO pool
Here is a simple example of how Utxo can implement using C ++:
`CPP
#Include
#Include
#Include
UTXOPOOL class {
the public:
// add a new excellent output to the pool
VOID addoutput (Const Uint256 and Hash, Size_t Count) {
// Update the Hash set with newly added outputs
UpdateHashSet (hash);
}
// Restore the unable to exit from the pool
Const Uint256 & Getoutput (Uint256 hash, Size_t Index = 0) {
// organize outputs for your hash values in descending order
STD :: Vector Sorting;
for (uint256 i = hash; i <hash +count; ++ i) {
IF (! SORDDEDOUTUTUTUTEPUTS.EMPLY () && classidoutputs.Back ()> i) RUBTAR;
SortdedoutoutPuts.push_back (I);
}
// returns output in the specified index
Return SortedoutPuts [index];
}
private:
// Update UTXO set using continuous new block trips
VOID UPDATEHASHSET (UInt256 hash) {
// Simulize blocking the ITERDO block through every excellent output
For (Size_t I = 0; I <count; ++ i) {
Uint256 output = GetunsPentoutPut (I); // I suppose this function extracts unlimited output from the pool
IF (! HashSet.Contains (output)) {
Hashset.insert (departure);
}
}
}
// Simulize the ITrando scanning block through each incredible output and its index
STD :: vector GetunsPentututPut (SIZE_T) {index) {
// It is assumed that this function returns from a group not affected by its index
return {};
}
private:
// set hash that is used to store trips from impermeable
STD :: Unorded_Map <Uint256, STD :: Vector > Hashset;
};
Proven procedures
At the construction of the UTXO pool:
- Use an adequate data structure (such as a linked list or table hash) to store and restore effectively.
- Implement the cycles of periodic updates to remove the outdated output Hashu from the group.
