Initializing the Ethereum Utxo Database
The Ethereum Virtual Machine (EVM) uses an exclusive identical known as the non -spent transaction output (UTXO) to track non -blockchain transactions. This database is used to manage and check the transaction property, ensuring that each output has exactly one input. In this article, we will die how the utxo database is initialized at Ethereum.
Generating Ids Utxo
(UTXO). This id is used to track non -spent transactions created from the original input of each transaction. The utxi id consists of 20 characters in hexadecimal format.
The UTXO Generation Process Involves Several Steps:
- Transaction Creation :
2.
`Python
For Block in Blocks:
For transaction in the block:
utxo_id = get_utxoinputtransactionid (transaction)
TX_DICT [UTXO_ID] = None
Get_utxoinputtrasaationd () to generate id utxo. It is assumed that this function is implemented in other parts of the code base.
UTXO Database Initialization
The utxo database is initialized iThe on all Non -spent Transactions and removing them from Memory:
- Utxo removal : for each Block, itra on all transactions:
`Python
For Block in Blocks:
For transaction in the block:
utxo_id = get_utxoinputtransactionid (transaction)
If Not TX_DICT [UTXO_ID]:
Remove the utxo from memory (for example, using thedelinstruction or a garbage collector)
Del TX_DICT [UTXO_ID]
- UTXO Database Initialization : Initialize the utxo database creating an empty dictionary:
`Python
utxodatabase = {}
For Block in Blocks:
For transaction in the block:
utxo_id = get_utxoinputtransactionid (transaction)
TX_DICT [UTXO_ID] = None
Initialize the utxo database with an available utx list (for example, usingliste set)
Utxodatabase [UTXO_ID] .UPDATE ([I To I At Interval (1000)))
Initialize the utxo database by creating an empty dictionary utxodatabase. Then we iterate all non -spent transactions and add them to the utxo database. .
Note
:
Database is initialized and ready for use on the Ethereum virtual machine.
