Ethereum: Understanding witness data during the IBD in plum mode
In Ethereum, the distance between block (IBD) allows a more efficient and scalable network by pruning redundant transactions. However, this process also leads to the discharge of unnecessary witnesses during the initial block discovery phase (EII). In this article, we will delve into why the witnesses are downloaded during the III in plum mode and we will provide information about their implications.
Why do you discharge nodes download witness data during the IBD?
During the III process, Ethereum nodes must update their blocks and transactions to ensure that they know the most recent information. This includes downloading new data from previous block witnesses. However, some witnesses are marked as assumevalid, indicating that it has been correctly verified by a node (for example, through Merkle’s root or other validation mechanisms).
Despite this, many nodes still choose to download these witnesses marked during the IBD in plum mode. There are several reasons for this behavior:
- Network word : pruned nodes can be slower and more hungry for energy than not pronounced nodes due to their reduced bandwidth. When downloading data from unnecessary witnesses during the II, they can keep resources and maintain a faster network.
- Reduced latency : If the nodes could download all the necessary witness data in advance, it could lead to greater latency on the network. Download only what is needed to reduce this latency and allows a faster transaction processing.
Why not the non -predominant nodes also download witness data during the IBD?
You may wonder why unm administrated nodes do not follow similar behavior. Reason lies in Ethereum’s validation mechanisms:
- Merkle root : The nodes not pronounced generally trust Merkle’s root, which serves as a work test. While Merkle’s root is verified by all nodes during the IBD, it does not guarantee that unpurresed nodes will also download witness data.
- Assumed marker : When a node marks a data like
assumevalid, it means that it has been correctly validated by another node. This marker serves as a signal to other nodes in which the data is trusted and can be downloaded safely.
Conclusion
In conclusion, Ethereum nodes can discharge witness data during III in plum mode due to several reasons, including network pruning, reduced latency and dependence on validation mechanisms such as Merkle’s roots and assumed markers. While these downloads may seem unnecessary at first glance, they help maintain a faster and faster network.
As the Ethereum network continues to evolve, understanding this behavior is crucial to optimize its performance and scalability. Recognizing why the witnesses are downloaded during the IBD in plum mode, we can take measures to mitigate any negative impact and ensure that the network is efficient and reliable.
