Topic: How to monitor zero-conf transactions? (Read 573 times)
Thanks, that works great.
You need to check the memory pool (bitcoind). Something like getrawmempool. https://en.bitcoin.it/wiki/Original_Bitcoin_client/API_calls_list. In bitcoinj I think unconfirmed transactions matching the wallet are available from the wallet.
How do I monitor incoming transactions as they occur (before they're accumulated into a block)? Are they in one of the blk.dat files that bitcoind creates, or are there only confirmed blocks in those files? Does bitciond create a file of pending, unconfirmed transactions? I can use python or C, or really anything.
