I thought my full node support all services. But I just found out from https://en.bitcoin.it/wiki/Protocol_documentation#version that it does not support NODE_GETUTXO.

I have no clue at all about what it actually does though . But according to https://github.com/bitcoin/bips/blob/master/bip-0064.mediawiki, it seems to be good to enable it to be able to further check double spending.

Could anyone explain what NODE_GETUTXO actually is, how to enable it on my full node and its impact (if any) on my full node that I need to consider?

Thanks a lot in advance.
