Description:
This PR Introduces the
MultipleBlocksEstimatorthat tries to get thedesiredBlockCountmost recent blocks to determine a more stable compute unit price.How It Works:
Configuration:
BlockHistorySizeis used to configure this estimator.Fetch Recent Blocks: Tries to retrieve specified number of the latest confirmed blocks from latest slots based on the configured
BlockHistorySize. Not all slots have a block.Concurrent Processing:: Fetches each block concurrently while limiting the number of simultaneous operations to prevent rate limiting.
Extract and Aggregate Fees: Parses each block to extract compute unit prices from transactions. Calculates the median compute unit price for each block.
Determine Overall Average: Aggregates the median prices from all fetched blocks. Computes the overall average to set as the current base compute unit price, ensuring it stays within predefined minimum and maximum config limits.
