Getting a txn-mempool-conflict #7

Closed FrozenPrincess closed 7 years ago

FrozenPrincess commented 8 years ago

The first attempt I tried ended with 66: mempool min fee not met so I ran this:

./doublespend.py 1CfryEy3uwuKPbrQGETbDFQNuvJV1TBx7g 0.005 --fee1 0.0001

Ah, the first transaction it created: dad38fc66d2f23645559893c3583be8d47c17779cfb9634ba38e8e040c24db3f

appears to not be bip125 replaceable, so that's why my node rejected it.

Is there a way to get it to generate and double spend bip125 replaceable transactions? As that is what I would like to actually be testing

You should run this script with replace-by-fee patch.

petertodd commented 7 years ago

@FrozenPrincess Bitcoin Core now supports a command line option to make it generate BIP125 replacable transactions: https://github.com/bitcoin/bitcoin/pull/8601

The doublespend.py script doesn't support generating them right now, but that'd be a useful command line option to add to it.

And yes, you should be using the replace-by-fee patch; latest is here: https://github.com/petertodd/bitcoin/tree/replace-by-fee-v0.13.0
