Ethereum: Understanding the download of witnesses during IBD in pruning mode
In Ethereum, the distance between the distance from the block (IBD) allows a more efficient and scale network, organizing unnecessary transactions. However, this process leads to the removal of unnecessary data on witnesses during the original detection block (IBD) phase. In this article, we will deepen why witnesses are downloaded during the IBD in pruning mode and provide an idea of their consequences.
Why do the trimmed nodes lower witnesses during the IBD?
During the Ethereum IBD process, they must update their blocks and transactions to ensure that they are aware of more information. This includes downloading new data on earlier block witnesses. However, some witnesses are marked as Assumevalid, which shows that it was correctly verified by a knot (for example, through the root of Merkle or other validation mechanisms).
However, many nodes still choose to lower these marked witnesses during the IBD in cutting mode. There are several reasons for this behavior:
The pruning of the network
: The trimmed nodes can be slower and smoother than the nodes that are not food due to their reduced bandwidth. By lowering unnecessary witnesses during IBD, they can retain resources and maintain a network faster.
Reduced latency : If the trimed nodes lower all necessary witness data in advance, this may lead to increased network latency. The download only required reduces this latency and allows transaction processing faster.
Why weren't the nodes cut off also not lowering witnesses during the IBD?
You may be wondering why the nodes that do not feed do not follow this behavior. The reason is in Ethereum validation mechanisms:
MERKLE ROTE
: NOT BUILDED NODS usually depend on the root of Merkle, which serves as proof of network work. Although Merkle's root is checked by all nodes during the DII, it does not guarantee that we non -feeders also download witness data.
Tag Assumevalid : When a node marks some of the data asassumevalid, it means that it is validated correctly by another node. This marker serves as a signal for other nodes that are entrusted by data and can be downloaded safely.
Conclusion
In conclusion, Ethereum nodes have trimmed, lower witnesses during IBD in pruning mode for various reasons, including network pruning, decreased latency, and reading validation mechanisms such as Merkle roots and assumed markers. Although these downloads may seem unnecessary at first glance, they help keep a network faster and scale.
As the Ethereum network continues to develop, understanding this behavior is crucial to optimizing its performance and scalability. By recognizing why witness data is downloaded during IBD in PLA mode, we can take steps to mitigate negative impacts and ensure that the network remains effective and reliable.
