22018-09-02T00:11:47 <echeveria> is there any reason the p2p messages have checksums at all?
32018-09-02T00:12:29 <echeveria> all of the data in messages ends up being hashed regardless somewhere down the line.

52018-09-02T00:23:57 <sipa> echeveria: there as a bug once in the message deserializer, and someone thought it was a good idea to be able to detect future things like that by adding a checksum
62018-09-02T00:24:44 <sipa> this was in 0.2.x days
72018-09-02T00:24:48 <sipa> early 2010 maybe

92018-09-02T00:36:10 <echeveria> kind of annoying to keep them in memory to hash them though.

142018-09-02T01:26:48 <gmaxwell> echeveria: you don't have to, you can compute the hash incrementally.
152018-09-02T01:26:59 <gmaxwell> (in fact, bitcoin core computes the hash incrementaly)
162018-09-02T01:27:53 <gmaxwell> The proposed encrypted transport eliminates the checksum, but introduces a mac... but at least that does something useful (protects traffic from tampering)
172018-09-02T01:29:25 <gmaxwell> (and before anyone things "but bitcoin traffic doesn't really need to be tamper protected" -- it's important to authenticate encrypted data or you can use targeted tampering to extract small amounts of data from encrypted links by tampering and observing what happens)

772018-09-02T11:00:44 <sipa> alexneudatchin: ok, that's good to know. why is using sta a problem in this case?
782018-09-02T11:01:37 <jonasschnelli> alexneudatchin: why not use QWinTaskbarProgress?
792018-09-02T11:05:41 <jonasschnelli> I expect that a lot of functionality your are implementing in 14090 is already usable via the QT dependency: https://github.com/qt/qtwinextras/blob/5.11/src/winextras/qwintaskbarprogress.cpp
802018-09-02T11:05:41 <jonasschnelli> https://github.com/qt/qtwinextras/blob/5.11/src/winextras/qwintaskbarbutton.cpp
812018-09-02T11:05:42 <alexneudatchin> mta could be used standalone coz it has own message engine.

I'm kinda stuck and don't know what i can do to keep testing . thx

942018-09-02T11:51:00 <as1nc> yeah but i'm purposly building software that can play on testnet :) regtest would be local only. just asking :)

1012018-09-02T11:59:03 <as1nc> I'll see if it's gets confirmed. but i think i have a problem, I'm using electrum, and recently none of the tx ever got confirmed
1022018-09-02T11:59:12 <as1nc> dont know if it's an electrum problem
1032018-09-02T11:59:37 <wumpus> could be, but also testnet can have some issues sometimes, it's not for nothing that sipa recommends using regtest
1042018-09-02T12:00:35 <as1nc> yeah i understand, but i'm bulding a service for user to accpet bitcoin via web interface providing only their extended public keys, and I really want to provide a testnet api

1082018-09-02T12:03:29 <as1nc> if it ever gets confirmed, i'll keep you posted, but i guess testnet does not work for now :(

1102018-09-02T12:06:11 <wumpus> I don't know if there are any dedicated ones at all, it looks like people just dump hashpower onto testnet once in a while, probably when they want to test
1112018-09-02T12:06:14 <as1nc> wumpus, did you send the coin within bitcoin core, or another wallet ?

1312018-09-02T12:51:00 <wumpus> fee estimation is another non trivial thing on testnet
1322018-09-02T12:51:27 <wumpus> (it's not easy on mainnet either, but testnet is so unpredictable)

1392018-09-02T13:21:36 <wumpus> I guess if it's worthwhile someone could pick up the code and go on with it but I don't know, seems it has plenty of problems too
1402018-09-02T13:27:21 <fanquake> wumpus I'll make a comment to that affect, and if the response is un-constructive I'll close the PR, and open an issue with implementing that feature.
