If the tag is `blockHash` and `requireCanonical` is `true`, the callee SHOULD additionally raise a JSON-RPC error if the block is not in the canonical chain (the recommended error code is `-32000: Invalid input` and in any case should be different than the error code for the block not found case so that the caller can distinguish the cases). The block-not-found check SHOULD take precedence over the block-is-canonical check, so that if the block is not found the callee raises block-not-found rather than block-not-canonical. ##### `Data` @@ -381,7 +400,7 @@ Executes a new message call immediately without submitting a transaction to the |#|Type|Description| |-|-|-| |1|{`object`}|@property {[`Data`](#data)} `[from]` - transaction sender
