From a performance perspective using RPC for utility-only functions that could be performed locally, especially something that requires pumping over megabytes of data, is a bad idea. I can imagine this is useful as a quick hack but it's not something to encourage. |

@Sjors please no overloading, especially when the purposes are different. |

There is a performance penalty in not using blockindex->GetBlockHash(). Suggestion:
result.pushKV("hash", blockindex ? blockindex->GetBlockHash().GetHex() : block.GetHash().GetHex());| } | ||

Could lock after DecodeHexBlk below.
Disagree, if we end up adding this, then adding it as a separate "pure utility" (as in "this function could run without node") RPC call with disparate functionality is best. I think coaxing it into an existing server function unnecessarily complicates the interface. |

I'm a -0; I agree with the sentiment that this should be done in a standalone tool rather than part of bitcoind. |
I find this useful for looking at not-PoW-valid blocks rather than using an external parser.
