Ethereum: Is UTXO set from scratch calculated with new full nodes?
The decentralized, open source architecture of the Ethereum network depends on the complex nodes and block systems to ensure the integrity and security of the blockchain. It is based on the calculation and inspection of transactions, including the creation and validation of the unparalleled transaction output (UTXOS). In recent years, there have been concerns about the validity of the UTXO kit, calculated by new full nodes that join the network. This article will go into the current sense of how the Ethereum Utxo set is calculated and whether new full nodes simply trust the set.
Background: UTXO Kit
The UTXO (unexpected transaction output) sets a list of all transactions that a particular user or group has spent on a specific block. Each UTXO consists of a reference to the transaction, the amount spent and the associated private key. This information is essential for verifying the user’s asset validity.
Full Node Calculation: A complicated process
New full nodes are responsible for joining the Ethereum network and participating in the validation process. During this time they must calculate the UTXO kit from scratch that includes:
- When receiving the latest blockchain data using an interplaneted file system (IPFS) or by downloading them from Ethereum Mainnet.
- Passing the headed block received to obtain relevant information, including transaction revenue and transaction fee.
- The creation of a new Merkle -used transaction output tree, which serves as a reference to the transaction test.
The calculated UTXO kit is then used to test the authenticity and integrity of all current block transactions.
Trust for a pre -calculated kit: Ordinary practice
Ethereum is a common practice if the nodes trust the previously received UTXO kit. This ensures that new nodes can join the network by manually calculating the entire UTXO kit from scratch. The above set is based on blockchain data received by the node during the initial setup.
New Node Behavior: Is it calculated from scratch or trust in a set of above?
When a new full node joins the network, it usually receives the latest blockchain data using IPF or downloads it directly from Ethereum Mainnet. At this point, there is no clear indication that it should copy the UTXO kit.
However, in recent years, some studies have shown that new nodes may choose to calculate the UTXO kit from scratch by joining the network. This could be due to a variety of factors including:
1
Safety concerns : Loss of previously calculated data may leave nodes vulnerable to attacks that use previously calculated transaction information.
- Resource Restrictions : Calculation of the entire UTXO kit from scratch may require significant computing resources, which may not be provided for new nodes with limited hardware capabilities.
Conclusion
In conclusion, although it is customary that new full nodes of Ethereum are reliable for the pre -limited UTXO kit, there is also the possibility that they choose to repeat the kit from scratch. This raises questions about current network security and reliability, especially given the recent security problems and resource restrictions.
suggestions
1
Node operators : Node operators should consider the introduction of measures to prevent the assemblies from calculating UTXO’s set from scratch by joining the network.
- Security updates : Ethereum developers can prioritize the safety of nodes, including relying on previously calculated data.
