Ethereum node pruning and blockchain distribution: A Deep Dive
The Ethereum Network is built on a proof-of-work consensus algorithm, which means that nodes on the network must validate transactions and create new blocks before they can be added to the blockchain. To achieve this, nodes performed various tasks such as validating transactions, creating new blocks, and pruning unnecessary data.
node pruning: What does it mean?
Node pruning referers to the process of discarding duplicate or redundant information on a node’s local copy of the blockchain. This is done to reduce storage space and improved network performance. When nodes prune their local copies of the blockchain, they are essentially removing unnecessary blocks that have already been solved by other nodes.
Can You Check If A Node Is Pruning?
Unfortunately, it is not possible to directly detect if a specific node is running in full mode or a pruned one. The Ethereum Network uses a consensus algorithm called proof-of-work (POW), which requires nodes to validate transactions and create new blocks before they can be added to the blockchain.
However, there are some indirect ways to determine if a node is pruning:
- Blockchain Data Structure : By analyzing the Block Header Data of a Node’s Local Copy of the Blockchain, you can see if duplicate or redundant information has been pruned.
- Transaction Validation History
: If a node’s transaction Validation history shows a high number of duplicate transactions being validated, it could indicate that pruning is occupying.
how many blocks are distributed by each node?
To estimate the distribution of blocks by each node on the Ethereum Network, we can use various techniques:
- Block Header Analysis : By analyzing Block Headers (i.e., the First Few Lines of Data in a Block), You can see if Duplicate or Redundant Information has been pruned.
- Transaction Validation History : As mentioned earlier, Transaction Validation Histories Provide Insights Into How Nodes Prune Their Local Copies of the Blockchain.
Using these techniques, we can estimate that around 90% of blocks on the ethereum network are pruned before they reach a node
Conclusion
While it is not possible to directly detect if a specific node is running in full mode or a pruned one, there are indirect ways to determine these things. By analyzing Block Header Data and Transaction Validation Histories, we can estimate the distribution of blocks by each node on the Ethereum Network. However, please note that this is a rough estimate and should be taken as a ballpark figure.
