1  Bitcoin / Project Development / Re: [ANN] Percy, Persistent Bitcoin Transactions -- Ended on: April 09, 2018, 05:11:03 AM
Hey all. I'm going to end this project. Mempool is low now. Code is still up if you want to use it. But the truth is that Bitcoin is long term going to be useful only as a backed for the lightning network. With that as the goal of Bitcoin this no longer makes sense to maintain (and pay for).

If you truly need this service message me and I can help you set up something. It's light enough where it can run on a RPI if it doesn't have to handle a ton of transactions.

Also the code is still up here and if there's some unknown demand for this service I can always start it back up again.

Good luck!

Hey guys doing some testing with Electrum 3, it looks good. However I've noticed that how accurate my ability to inspect the mempool is based heavily on which electrum server I'm connected to. I'm going to look into a pruned node specifically for this project, especially as the mempool is incredibly backed up due to blocksize constraints.

Also an update. If you attempted to add a transaction recently it probably failed. I think I may have found a reliability bug in the system. I'll attempt to mitigate.

Hey guys, just an update. I'm going to try to find some time this weekend to test Percy with Segwit transactions. Right now segwith txs are servicing less than 1% of the total transactions on bitcoin. Bu I expect that to rise, given the discount (source). I should have more for you "soonish".
5  Bitcoin / Project Development / Re: [ANN] Percy, Persistent Bitcoin Transactions on: June 16, 2017, 04:48:26 AM
Interesting.I'm still having second doubts if this will work.What if I pay really low fee,the case where the transaction gets dropped off the mempool (and we know it).What is the point of pushing it over and over when we know it will eventually be dropped off due to low fees.Or the case is different using Percy ?

First if it's truely too low you can cancel it out of Percy. When you add a transaction you recieve a confirmation string that can be used later to cancel the transaction. But, given enough time, most transactions will find a "low point" and eventually confirm, as evidenced by the 15.7 sat/byte transaction above. So say you look at 21's bitcoin fee reccomendation (as 226 bytes) but you say, man that's too high. You could pay significantly less and even if more transactions come in you could keep yours there as others fell off.

interesting project. just some thoughts that i wanted to share:

first of all as far as i know and the wiki says, "Transaction expiration"[1] is never going to happen. in other words when you send a transaction it will stay out there for ever, most probably.
i currently have a transaction with zero fees that is out there for more than 1.5 month Smiley

also on top of that the maximum mempool expiry time was increased to 2 weeks [2] so transaction aren't going to be forgotten that easily.

also why did you choose 6 hours

[1] https://en.bitcoin.it/wiki/Transaction_expiration
[2] https://github.com/bitcoin/bitcoin/commit/a72f76ca3d5d2f259d308f65810891389f728e9e

For the most part miners tend to try to keep stardardish rules on evicting. While they definitely "can" process a transaction that's been published (and you should sweep transaction outputs where you've "reclaimed" a transaction from to avoid this) they tend not to.  So even if it shows up on a block explorer there's still a percentage of miners and nodes that probably no longer have it in their mempools. However re-broadcasting makes people re-broadcast and it tends to re-propogate among nodes that no long have it in their mempools.

0.14.x+ have this commit but 0.13.x and less don't. But most nodes and especially most miners aren't running 0.13.x (See the tags in your commit). Most of them still evict a transaction after 72 hours. Even if nodes kept transactions for 2 weeks instead of 72 hours, there's a 300MB limit on total transaction in the mempool (by default) [1]. According to blockchain.info mempool size hit 120MB a couple of times over the last 60 days (with most nodes on < 0.14.x code). So when transaction persistentce length rises by a factor of 4 I expect mempool requirements to rise to 480MB which means nodes configured with defaults will be evicting transactions.

6 hours was chosen with no real scientific reason. I tested a few variables on my Raspberry Pi text box. If you have a better time or reason I'd be happy to test it out.

New record. Percy just helped a 15.7 sat/byte transaction confirm after sitting in the mempool for almost a month (and in percy since the 3rd of June). So if you can wait, we can help you get a small transaction confirmed.
7  Bitcoin / Project Development / Re: [ANN] Percy, Persistent Bitcoin Transactions on: June 04, 2017, 08:09:57 PM
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 :

TXIDFee (sats/byte)Time in Percy
3bcd...51.68 Days
777d...72.17 Days
f8c1...19.64 Days
e6af...58.94 Days

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

Would this potentially cut down on the overall delays in processing the Bitcoin transactions that many of us have seen lately?

No, this targets the other half of the formula. Those with transactions who never confirm. In some specific circumstances it might help your transaction confirm faster; but that's pretty unlikely.

Hey guys I created a tool, percy, that will make your transactions persistent by resubmitting them periodically to the network.

Ideal use case is for someone with a transaction where they can afford to be patient (like a re-organizationing transaction to ones self or an incoming transaction with a lower fee and a known customer). Or where you can let subsequent child transactions add an additional bounty on payment (like when re-organizing coins in your wallet). It doesn't do anything too complex really. It just resubmits your transactions to the network every 6 hours until it confirms. So even if you put in a transaction during bitcoin's "busy" periods with an average fee this will continue to resubmit the transaction to the network until it confirms. The method used to do so is not complex (see source code here) and can be self hosted if desired (I run a test box on a raspberry pi out of my home).

Would love your feedback and if you spot a bug or a feature request please report it on github.

According to 21.co's Fee Chart there have been 60k+ transactions that have confirmed in the last 24 hours with a fee < 100 sats/byte. If you can be patient Percy can make sure your transaction persists until it's one of those confirmed.

Hey searchtrade. I can't seem to report bugs via the interface on the site. So that's one issue.

The second is that I keep getting logged out. It really kills the use case if I have to re-login every couple of hours to do a search. I assume that's to keep the user wallet safe (which is reasonable). Is it possible to have either a second password for the wallet or require re-authentication with any wallet actions and allow a "keep me logged in" option for logging in? I'm trying to test drive search trade as my regular search engine but this issue is slowing me down considerably.

If you said that to any person in the US, they would laugh you back to your mom's basement.

The quoted incident was from Denmark. Definitely a Western Country.

Also here is something that most people mistake about islam is that "Islam hates other religions" for this I say, Islam does not hate ANY religion

My religion is drawing cartoons of Religious figures having dirty nasty sex with pankakes, a buffalo and Paris Hilton. When I do so for Allah how many Muslims will call for my death? When I do so for <insert non-islam religion's important figures here> how many <insert non-islam religion's general name> will call for my death?

The answer for the second is "almost nobody"; for the first is "a lot".

IRL I don't draw cartoons of Religious figures having sex. In fact I don't draw at all. But I love the freedom to do so about any topic that I should choose. That's freedom. If some people can't respect my freedom then f'ck them.

https://yourlogicalfallacyis.com/special-pleading

Not really accurate here. We're talking about things that actually happen. This wasn't me moving the goal posts. Musilms, even Muslims in Western Countries, believe that I should be killed for making fun of their religious figures. That ideal that I have to try to appease a particular group, or limit my freedom for a particular group or they will attempt to kill me is not an ideal that I take kindly too.

NICE to see P2 POOL users attacking other pools and their owners and members both from their normal users names and hiding behind fake accounts just an example of the p2 pool users handy work can be found here

https://bitcointalk.org/index.php?topic=456463.0

They even gone as far as attacking a legit world wide company today and an user that not even possible connected to the pool that a select few p2 pool users have been targeting for few weeks NOW.....

Ps there is now a p2 pool scam thread LETS see if the users in question back off or keep going as it does not like good for the p2 pool set up in general and what it stands for to on one hand they want to split the hash rate up as much as they can to then attack start up pools etc with baseless fud campaigns that a select few are carrying out......


Atm that P2 pool scam thread is a open thread with no details in it.   It up to the few bad apples in here what happens next if we go to town on the p2 pool or not
...

Sayeth What? . *Checks thread* Promo for VaporPool.

I'm thinking of switching to P2Pool but don't want to run my own node. I've looked at the node list and some like p2pool.org seem like scams. Can someone suggest a node in the southeast i"m in Charlotte NC? Would be running about 10-15TH depending on how I decide to split it. Thanks

It's generally seen as best to run your own node. However you can try looking at the list here for one that has good ping times/location to you.

btcaddrtocsv v0.1 relased

Hello everyone Id like to announce the v0.1 release of btcaddrtocsv. A CLI tool that I use to convert public bitcoin addresses to csv files for import into a multitude of tools. Id also like to announce that in addition to the basic python script that can pull one address Ive also (in head) created a bash script to cycle through a number of BTC addresses. Here is a link to the github page for the project and here is the link for the 0.1 release.

Please remember that this tool depends on the blockchain.info api so if youre using it on a machine that cant reach the internet it will not work. Ive been using this tool successfully for months now so I believe it to be stable. Please report bugs to the issues page on github. If you like what Im doing here please consider donating using address 14UbKCCjxpU1jnzZHKGRf8xaP2a5RS4n9R.

Please remember, if you are using the new bash script to process several addresses at the same time, to create a directory called csvs for your csv files to be output to.

Hi guys bit of a noob question. I've got version 13.4 of the pool software. That's the last release on Github. Is that the version that is considered "best?" or is there another build that I should be running. Just asking because I notice that a lot of pools are running different builds.

If your only mining BTC that is the build you want (https://github.com/forrestv/p2pool), if you are looking for some more exotic coins Rav3nPL's build has many already added (https://github.com/Rav3nPL/p2pool-rav).

Generally Bitcoin with some merged alt coins. However the difference between his 13.4 release and the latest head is nearly 8 months of development. I can't help but think that there must be a release in there that adds significant support/features/performance and is particularly stable. Espeically since when I take a look a the running nodes I find a large variety of versions newer than 13.4
