 31 2019-02-15T00:49:28  <gmaxwell> jb55: why 'this kind' is a pretty easy answer: we use a cyclic linear code because after extensive research, it's the only class of code we know of that can achieve good guarentees for the "user makes random single character errors" channel.
 32 2019-02-15T00:49:29  <aj> meshcollider: curses, foiled again
 33 2019-02-15T00:50:40  <gmaxwell> jb55: other kinds of codes, like a simple CRC don't operate at the 5-bit-character level, and so can't guarentee e.g. that a bad input with 3 character errors will be detected.
 34 2019-02-15T00:53:23  <gmaxwell> jb55: and other kinds of codes (like ones constructed from arbritary non-linearities) are computationally intractable-- as far as anyone yet knows-- for detecting as many errors as bech32 does.

 40 2019-02-15T01:04:29  <jb55> gmaxwell: ah, interesting... thx.
 41 2019-02-15T01:07:13  <jb55> was wondering why I was dealing with 5bit words when working on a bech32 lib...
 42 2019-02-15T01:07:54  <jb55> gmaxwell: is there a particular reason it's 5 bits?
 43 2019-02-15T01:11:06  <jb55> oh I see the extra 3 are for error correction
 44 2019-02-15T01:12:51  <gmaxwell> jb55: it's 5 bits because log2(32) is 5. -- the number of bits per character is a product of the character set size.  The character set size is chosen to be relatively small because it makes entering it easier.  Mixed case in base58, for example, makes it really hard to read addresses out loud (e.g. over the phone).
 45 2019-02-15T01:14:00  * jb55 slowly getting it
 46 2019-02-15T01:14:18  <gmaxwell> The exact character set size could be another value, but (1) if it's a power of two its much easier to convert to and from bytes, since each character represents an integer number of bits.  and (2) for it to be feasable to design a linear error detection code over it, the size must be a prime or a prime raised to some power.  (so base58 is out)
 47 2019-02-15T01:14:51  <sipa> jb55: there are no bytes involved anywhere
 48 2019-02-15T01:15:07  <sipa> everything is 5-bit symbols; both the 'data' and the 'checksum' are 5-bit units
 49 2019-02-15T01:15:14  <jb55> ahh
 50 2019-02-15T01:15:40  <sipa> the reason for that is because we expect errors that are affecting groups of 5 bits simultaneously
 51 2019-02-15T01:15:40  <gmaxwell> Of the character set sizes that allow for easy conversion two and from bytes... 16 characters is overly restrictive (bigger addresses), and 64 is too many (requires using characters that are hard to distinguish/hard to type).
 52 2019-02-15T01:15:54  <sipa> jb55: because 1 character in base32 = 5 bits
 53 2019-02-15T01:16:51  *** mistergold has joined #bitcoin-core-dev
 54 2019-02-15T01:17:54  <gmaxwell> A pretty good case could have been made for base-31, base-29, or base-27-- which would allow excluding some more visually similar characters without being much longer, but the code to convert from binary data into those bases is somewhat irritating.
 55 2019-02-15T01:20:27  *** mistergo1d has quit IRC
 56 2019-02-15T01:21:24  <jb55> and 7 bits wouldn't work because the character set size would be too large... 3 would be too verbose. and the log of other bases are fractional so conversion is annoying, if I'm getting this right
 57 2019-02-15T01:21:35  <sipa> indeed
 58 2019-02-15T01:21:52  <sipa> 6 bits would work too; base64 is pretty common, but it means mixing upper and lowercase
 59 2019-02-15T01:22:15  <sipa> there are only 94 printable ascii characters, so 7 bits is kinda out
 60 2019-02-15T01:22:32  <sipa> unless you want to mix in things like poop emoji
 61 2019-02-15T01:27:24  <jb55> gotta capture that millenial market, should have went with basemoji
 62 2019-02-15T01:27:43  <gmaxwell> mixed case is hard to read, also irritating to type on mobile devices, also results in more similar character mistakes.

 65 2019-02-15T01:29:09  <gmaxwell> if your metric is "how long does it take to successfully transfer 200 bits of data between two humans, where one reads and speaks the other hears and types" a base somewhere between 25 and 32 is likely optimum.
 66 2019-02-15T01:30:16  <gmaxwell> more than 32 and you're forced to use easily confused characters (and/or prefixing every letter with "upper" "lower" and causing a 2x slowdown)
 67 2019-02-15T01:31:28  <jb55> base32 is my go-to, although I use a modified variant that replaces o,i with 8,9. I always thought that choice was kind of odd in the standard base32 encoding.
 68 2019-02-15T01:31:45  <gmaxwell> If your metric is copy and paste, the length/characters hardly matter except non-alphanum characters break the automatic copy boundary behavior in browsers.
 69 2019-02-15T01:32:01  <gmaxwell> jb55: there are like a half dozen different base32s that replace different characters.
 70 2019-02-15T01:32:36  <jb55> although it's not optimized phonetically, would be interesting to see a character set that is ideal for voice transcription instead of visual.

 73 2019-02-15T01:33:10  <gmaxwell> Our ommited characters are basied on minimizing visual confusion according to some NIST data.  Though later a research paper came out and had confusion data generated from millions of password entry attempts and it gave essentially the same results.
 74 2019-02-15T01:34:30  <gmaxwell> At least my thinking was the the visual component is always there (for human based transcription), while speaking is not always used.  Also, speaking errors depend a lot on your accient and/or if you're using something like the NATO phonetic alphabet (alpha bravo charley delta echo foxtrot..)
 75 2019-02-15T01:35:08  <gmaxwell> I think if that password entry data were available we would have used it instead of the NIST data, but I reran the analysis using it and got essentially the same result.

 81 2019-02-15T01:43:57  <gmaxwell> (I think also if we had the password data I would have spent more time exploring e.g. base-27, since we actually would have had a good criteria to use to exclude more characters)
 82 2019-02-15T01:48:51  <gmaxwell> One thing we were able to do in base-32 was make it so that if you only made the most likely mistakes then we are guarenteed to detect one more error. (we did this by choosing a character permutation that mapped the most likely errors to single bit errors, and choosing the code to also support up to 6 one bit errors)... this would have likely worked even better in base-27
 83 2019-02-15T01:49:09  *** mistergo1d has quit IRC
 84 2019-02-15T01:49:45  <gmaxwell> (both because we could exclude more characters outright, and because the analog would be mapping them to a single-trit error out of three trits per symbol.)
 85 2019-02-15T01:53:04  <jb55> gmaxwell: sounds kind of like compression wrt. most common symbols assigned to shorter prefix bit sequences? in this case instead of most common symbols you're describing most common human error symbols?
 86 2019-02-15T01:53:17  <jb55> if I'm understanding correctly
 87 2019-02-15T01:54:22  <gmaxwell> jb55: https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki#Bech32  no, look at the table there.  Visually similar characters like q/g or q/p are arranged so that their value differes only by 1 bit.
 88 2019-02-15T01:54:56  <jb55> ohh
 89 2019-02-15T01:54:57  <gmaxwell> (the table is dimensioned so that it's relatively easy to see the 5 dimensional 1-bit-difference hypercube...)
 90 2019-02-15T01:56:37  <gmaxwell> r/t r/y 8/0 c/e 8/h  almost all of the easier mistakes map to one bit differences.
 91 2019-02-15T01:58:13  <jb55> gmaxwell: so the smaller bit difference the less ambiguity in detecting which symbol has the error?
 92 2019-02-15T01:58:43  <sipa> jb55: the checksum itself was optimized to be slightly better for low-bit-error
 93 2019-02-15T01:58:54  <sipa> this is not an inherent property; it was selected for
 94 2019-02-15T01:59:14  <gmaxwell> the bech32 checksum will always detect if there are no more than 5 characters wrong,  ... or if there are no more than 6 bits wrong.
 95 2019-02-15T01:59:25  <gmaxwell> we specifically designed it for this behavior.
 96 2019-02-15T02:00:04  <jb55> and by designed you're referring to which symbol is assigned to which 5 bit number?
 97 2019-02-15T02:00:16  <sipa> no, the BCH code
 98 2019-02-15T02:00:19  <jb55> ah
 99 2019-02-15T02:00:27  <sipa> the character set was designed so that common errors are 1 bit only
100 2019-02-15T02:00:28  <gmaxwell> Picking the symbol ordering lets us map common mistakes to single bit errors.
101 2019-02-15T02:00:40  <sipa> the BCH code was designed to that 1 bit errors are more frequently detected
102 2019-02-15T02:00:41  <gmaxwell> Picking the error correcting code let us pick one that would detect 6-one bit errors.
103 2019-02-15T02:01:01  <sipa> the two are designed for each other
104 2019-02-15T02:01:37  <gmaxwell> there were many possible codes which have exactly equal performance for detecting whole character errors, but one of them also did better for bit errors.
105 2019-02-15T02:01:53  <jb55> picking a BCH code involves what, picking constants?
106 2019-02-15T02:02:06  <sipa> jb55: effectively, picking the generator
107 2019-02-15T02:02:18  <sipa> every cyclic code is uniquely characterized by its field representation and generator

116 2019-02-15T02:13:37  <Mischa010> i know 8 peers are connected to but how many can actually request and download a block at the same time?
117 2019-02-15T02:13:59  <Mischa010> i forgot the 'at the same time' qualifier!
118 2019-02-15T02:14:20  <gmaxwell> Mischa010: 8 peers are the number of outbound connections a node normally has, but they can have many more inbound. 70 inbound isn't uncommon.
119 2019-02-15T02:14:25  <sipa> Mischa010: this sounds like a question for https://bitcoin.stackexchange.com
120 2019-02-15T02:14:40  <gmaxwell> it's actually been answered in a number of forms on stack exchange before.
121 2019-02-15T02:14:50  <Mischa010> so there could be 70 downloading a block from a node at the same time?
122 2019-02-15T02:15:09  <gmaxwell> Mischa010: for the most part blocks aren't even transfered. because magic.
123 2019-02-15T02:15:57  <Mischa010> yes compact blocks is great
124 2019-02-15T02:16:11  <Mischa010> incidentally, thanks for all the great work!
125 2019-02-15T02:16:16  <gmaxwell> but yes, 70... as many as 125 in the default config, in fact... could be transfered at the 'same time'.
126 2019-02-15T02:16:49  <gmaxwell> because of how tcp works you cannot generally achieve capacity without many concurrent streams in any case.
127 2019-02-15T02:17:00  <Mischa010> yes that's true
128 2019-02-15T02:17:05  <gmaxwell> as each one will only send one rwin worth before having to wait for an ack.
129 2019-02-15T02:17:25  <Mischa010> although couldn't you just determine and set some maximum mtu per connection?
130 2019-02-15T02:17:37  <gmaxwell> fwiw, node here with uptime of a week has not send a single whole block to any peer.

145 2019-02-15T02:23:44  <gmaxwell> thats too narrow thinking, e.g. assuming a homogeneous network (equal speeds, equal delays on all links), fibre shows that the optimal distribution pattern (shortest time to reach all nodes) is achieved by round robining packets one at a time equally to each peer.
146 2019-02-15T02:24:34  <gmaxwell> because they'll each send the recieved packets to each of their peers. spreading more slowly than that fails to achieve the maximum bisection bandwidth of the network.
147 2019-02-15T02:25:43  <gmaxwell> (on an inhomogeneous network it's more complicated)
148 2019-02-15T02:26:11  <Mischa010> interesting, is there any literature on this?
149 2019-02-15T02:27:40  <gmaxwell> bitcoin specific, not that I'm aware of. There is a lot of lit on 'network coding' though, which covers many of these things.

424 2019-02-15T16:56:15  <midnightmagic> luke-jr: so I think atm without open-source firmware for the SAS chip (for those that have it onboard) and.. mm.. the ethernet controller (which I think is being worked on) and of course the default chassis they ship with, I think the risc-v people might have pulled slightly ahead in the FOSS race. I could be wrong.
