  2 2018-09-02T00:11:47  <echeveria> is there any reason the p2p messages have checksums at all?
  3 2018-09-02T00:12:29  <echeveria> all of the data in messages ends up being hashed regardless somewhere down the line.

  5 2018-09-02T00:23:57  <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
  6 2018-09-02T00:24:44  <sipa> this was in 0.2.x days

  9 2018-09-02T00:36:10  <echeveria> kind of annoying to keep them in memory to hash them though.

 14 2018-09-02T01:26:48  <gmaxwell> echeveria: you don't have to, you can compute the hash incrementally.
 15 2018-09-02T01:26:59  <gmaxwell> (in fact, bitcoin core computes the hash incrementaly)
 16 2018-09-02T01:27:53  <gmaxwell> The proposed encrypted transport eliminates the checksum, but introduces a mac... but at least that does something useful (protects traffic from tampering)
 17 2018-09-02T01:29:25  <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)

 77 2018-09-02T11:00:44  <sipa> alexneudatchin: ok, that's good to know. why is using sta a problem in this case?
 78 2018-09-02T11:01:37  <jonasschnelli> alexneudatchin: why not use QWinTaskbarProgress?
 79 2018-09-02T11:05:41  <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

 81 2018-09-02T11:05:42  <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

 94 2018-09-02T11:51:00  <as1nc> yeah but i'm purposly building software that can play on testnet :) regtest would be local only. just asking :)
 95 2018-09-02T11:52:22  <as1nc> so hard to test stuff on bitcoin :)

101 2018-09-02T11:59:03  <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
102 2018-09-02T11:59:12  <as1nc> dont know if it's an electrum problem
103 2018-09-02T11:59:37  <wumpus> could be, but also testnet can have some issues sometimes, it's not for nothing that sipa recommends using regtest
104 2018-09-02T12:00:35  <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

110 2018-09-02T12:06:11  <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
111 2018-09-02T12:06:14  <as1nc> wumpus, did you send the coin within bitcoin core, or another wallet ?
112 2018-09-02T12:06:32  <wumpus> bitcoin core ofc
113 2018-09-02T12:07:06  <as1nc> ok, would you mind keeping me posted if you see that tx confirmed ?
114 2018-09-02T12:08:06  <as1nc> i guess i can just follow on a block explorer

140 2018-09-02T13:27:21  <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.
