@taxmeifyoucan, this PR is ready for review. It seems I'm unable to add you or others as reviewers at the moment |
| Here is a simple diagram of a Receipt Trie, which follows the Merkle Patricia Trie flow for value lookups. | ||

| Receipt Tries enable light clients to efficiently verify transaction results provided by full nodes. Since light clients only store block headers, they rely on full nodes to query execution results. To ensure trustlessness, full nodes return not only the transaction results but also Merkle proofs derived from the receiptsRoot stored in the block header. This structure allows light clients to independently verify the legitimacy of the data without storing the full transaction history. |
There was a problem hiding this comment.
Receipts are not mainly for light clients but are useful for indexing data without re-executing transactions and regular full nodes download them during snap sync.
It would be ideal here to refer to some explanation of what is a receipt. It should be part of transaction anatomy page on the wiki but it's missing there :/
Also EIP 2718 should be mentioned on this page https://eips.ethereum.org/EIPS/eip-2718#receipts
