 ### Receipts Trie {#receipts-trie}
 
-Every block has its own Receipts trie. A `path` here is: `rlp(transactionIndex)`. `transactionIndex` is its index within the block it's mined. The receipts trie is never updated. Similar to the Transactions trie, there are current and legacy receipts. To query a specific receipt in the Receipts trie, the index of the transaction in its block, the receipt payload and the transaction type are required. The Returned receipt can be of type `Receipt` which is defined as the concentenation of `TransactionType` and `ReceiptPayload` or it can be of type `LegacyReceipt` which is defined as `rlp([status, cumulativeGasUsed, logsBloom, logs])`.
