Understanding how ethereum nodes find transactions on blockchain
Ethereum nodes play a decisive role in maintaining the integrity and availability of blockchain. The node is basically a computer that operates Ethereum software that allows it to verify the transactions and store them in the chain. However, finding specific transactions or UTXOS (non -distributed transaction outputs) may be difficult. In this article we immerse ourselves in how the nodes find these transactions in blockchain.
What are Merkle branches?
Merkle branch is a tree -like structure that is used to represent Hashu data collection. It allows efficient storage and obtaining large quantities of data, such as transactions or UTXO. When the node receives a new transaction or utxo, it creates a Merkle branch containing a unique combination of this data.
How do the node find a specific transaction?
When the client (light) SPV asks for a complete node for the Merkle branch containing a particular transaction, here it happens:
1.
- Merkle Branch Creation : The node creates a Merkle branch using data obtained from its database and the value of UTXO interest (specific transaction).
- HASH function: The node uses the hash function to combine a Merkle branch with an empty chain and creates a unique fingerprint digital fingerprint.
4
- Node returns a Merkle branch : The entire node sends a compiled Merkle branch to the SPV client, which can then use this information to verify the transaction.
What about UTXOS?
Similarly, when the node finds the address (UTXO value), it creates a Merkle branch containing its associated data. Utxos, however, do not have a fixed branch of Merkle because they are not directly linked to a specific hash transaction. Instead, the nodes use a tree
MERKLE
to verify the integrity of the transactions and ensure that all valid utxo are included.
In short, Ethereum nodes use a combination of hash, data structures (such as Merkle trees) and computational force for efficient storage and loading specific transactions or UTXO values ​​from blockchain. By creating a Merkle branch using data obtained from its database and the appropriate UTXO value, the nodes can verify the integrity of the transaction and ensure that it is valid for included in the blockchain.
Conclusion
Understanding how ethereum nodes will find transactions on blockchain is crucial to building efficient and safe applications in the Ethereum network. By using advanced data structures, such as Merkle trees, the nodes are able to efficiently store, load and verify transactions and UTXOS, ensuring the integrity of the entire chain.
