This is interesting. Do you have any data or example transactions showing a low fee? Would be great if this was another possible method of confirming low priority transactions in addition to the transaction accelerator.
Ya we saw the mempool drop pretty low this weekend so we had some long lived, low fee transactions confirm. Here are some examples :
Assuming your use case is disbursing payouts for nastyfans, this could at least in theory help you distribute them more reliably and ensure that they will eventually confirm when the backlog is low enough. The 19.6 satoshi/byte transaction is probably the closest to your ideal use case. Additionally, when adding a transaction, percy gives you a "confirmation string" that can be used to retire the transaction out of percy at a future date. So you could publish your low tx fee and if changes were needed later you could cancel it out of percy and let it fall off the network "naturally."
I've got a
issue in the project to parse transactions and store the fee information so that I can provide these types of stats dynamically in the
future.
Hope Nastypool is doing great!
Edit- Fixing links
