| - | : //Similarly, transaction receipts in go-ethereum are stored on disk as a single binary blob for each block. Fetching a receipt for a single transaction requires fetching and deserializing this blob, then finding the relevant entry and returning it; this is accomplished by the ''eth_getTransactionReceipt'' API call. A common task for API consumers is to fetch all the receipts in a block; as a result, node implementations end up fetching and deserializing the same data repeatedly, leading to ''O(n^2)'' effort to fetch all transaction receipts from a block instead of ''O(n)''.// | + | : //Similarly, transaction receipts in go-ethereum are stored on disk as a single binary blob for each block.
