Bitcoin core sendrawtransaction
Contents:
When a node receives a transaction from its peers, it uses an empty value for nAbsurdFee when calling ATMP you can see the values of nAbsurdFee removed in the Remove absurdfee from accepttomempool commit. Furthermore, there is no way for a node operator to set the maximum fee, e. The wallet, on the other hand, allows the user to set a maximum fee using -maxtxfee. PR redelegates fee checking from the mempool to the clients in order to make mempool logic less user-specific.
The main observable behavior change is in the error message, which is updated to include RPC. This only changes RPCs testmempoolaccept and sendrawtransaction.

There are no changes to the wallet reviewers may want to verify that this is not an issue. To be careful to preserve the fee protection offered to the user, the PR includes a few intermediate stages.
The author recommends reviewing each commit individually and confirming that the behavior is identical at each stage. Did you review the PR? There was some discussion as to whether AbsurdFee is policy or a client preference. What do you think, and how did you determine this? Compare the implementations of the testmempoolaccept and sendrawtransaction RPCs.
What are the differences? At what point would the node have this information on hand? Is this a performance concern?

Why is vout in input of the transaction you are crating 0, if it is 1 in the listed spendable transaction? The output number should match the one in the unspent transaction — FedFranz Sep 2 '19 at Add a comment.
