01:00 <sacarlson> yes I'm also interested in mulisig. I've read what I can find on it so far but no real examples of the process from sign to release of funds

01:02 <sacarlson> I've writen documents on how it's done on bitcoin so I would be glad to also help document your method

01:02 <sacarlson> examples are the best method to start

01:05 <sacarlson> aren't there any published projects that already use the feature? if not I guess my pokerth_accounting will be the first to publish an example app using multisig

02:31 <stellar-slack> <meetreks> any links to cross border transactions?

02:32 <stellar-slack> <meetreks> Like if I have to set up from the scratch, how the set up would look like?

02:37 <sacarlson> like usd > eur ?

07:28 <stellar-slack> <meetreks> sacarlson, yes

07:36 <sacarlson> so you would have to have two accounts with the oposite currency ballances a has 10usd b has 10eur do have that?

07:36 <sacarlson> on an issuer they both have as trusted

07:37 <sacarlson> they would both setup orders to the oposite that would cross in price say even trade 10usd for 10eur to make it easy

07:39 <sacarlson> that's about it then A would have his eur and B would have his USD

07:40 <sacarlson> before you setup the orders they could have looked at the order book to see what bids are being asked to know what to set there order value to

09:06 <stellar-slack> <meetreks> like USD to EUR

09:07 <stellar-slack> <meetreks> So

09:07 <stellar-slack> <meetreks> Let us say

09:08 <stellar-slack> <meetreks> I have one account-A

09:08 <stellar-slack> <meetreks> and that has 100 dollars

09:08 <stellar-slack> <meetreks> and another account-B

09:08 <stellar-slack> <meetreks> and that account has 100 EUR

09:09 <stellar-slack> <meetreks> now all i want is transfer 10 dollars from A to B

09:09 <stellar-slack> <meetreks> the result would leave A with 90 dollars

09:10 <stellar-slack> <meetreks> the result with leave B with 109 EUR (aster conversion)

09:10 <stellar-slack> <meetreks> question is

09:10 <stellar-slack> <meetreks> how do I do this with a trusted entity such as an isuer

09:11 <stellar-slack> <meetreks> Let us say I have an issuer-C who both A & B trust

09:11 <stellar-slack> <meetreks> so A sends to Issuer who in turn sends this to B

09:46 pixelbeat_ has quit [Ping timeout: 255 seconds]

10:28 <stellar-slack> <bartek> @sacarlson @ lukeburns you can read about multisig here: https://github.com/stellar/stellar-core/blob/master/src/transactions/readme.md and here are the JS examples: https://github.com/stellar/js-stellar-lib/tree/master/docs#creating-a-multi-signature-account

10:54 <sacarlson> meetreks no you don't send the issuer anything. the issuer is the one that sent you the original credit

10:55 <stellar-slack> <meetreks> The issuer - -is it with respect to the sender or the receiver

10:55 <sacarlson> example I setup the other day from_pair is the issuer the to_pair is you https://github.com/sacarlson/pokerth_accounting/blob/master/send_currency.rb

10:56 <stellar-slack> <meetreks> OK

10:56 <stellar-slack> <meetreks> so you send the fund_pair to the issuer and I get the funds from the issuer

10:57 <sacarlson> the to_pair when he has the credit from the issuer in this example from_pair he can now send or setup orders with that credit to your B

10:57 <sacarlson> no

10:57 <sacarlson> from_pair IS the issuer

10:58 <stellar-slack> <meetreks> OK, got it

10:58 <stellar-slack> <meetreks> just to reiterate

10:58 <stellar-slack> <meetreks> I am am sending a payment from my account to someones account

10:58 <stellar-slack> <meetreks> I first ask stellar the path

10:58 <stellar-slack> <meetreks> stellar returns the bets path

10:59 <stellar-slack> <meetreks> so I use the best path info

10:59 <stellar-slack> <meetreks> and from there who ever is my trusted entity

10:59 <stellar-slack> <meetreks> I initiate a payment from myself to the other party

10:59 <sacarlson> here is an example of sending native STR https://github.com/sacarlson/pokerth_accounting/blob/master/send_stellar.rb

11:00 <stellar-slack> <meetreks> can you validate the above sequence for me

11:02 <sacarlson> the path is only going to calculate the present price from the issuer you have chosen

11:02 <sacarlson> you can look at the books before you setup an order to decide what to ask or bid

11:04 <sacarlson> you then setup the order with the chosen issuer, if price of your bid is crossed your order will exicute

11:04 <stellar-slack> <meetreks> OK

11:04 <stellar-slack> <meetreks> I prefer to get the path before I issue the order

11:04 <sacarlson> path just provides you a look at the price

11:04 pixelbeat_ has joined #stellar-dev

11:05 <sacarlson> maybe the path your thinking of is chosing a differenc issurer

11:05 <sacarlson> different

11:06 <sacarlson> the value of an asset from one issuer may not be the same price of the same thing from another issuer

11:09 <sacarlson> and thanks bartek I'll take a look at those links you sent us

11:18 pixelbeat_ has quit [Ping timeout: 264 seconds]

11:22 <stellar-slack> <meetreks> Yes I am aware

11:22 <stellar-slack> <meetreks> but if the liquidity players are there in the market

11:22 <stellar-slack> <meetreks> I must get a better rate by calling path

11:26 <sacarlson> why don't you just setup two accounts with the script I sent you and setup trades between them to try it out

11:28 <sacarlson> I think you will find that path provides you that same info that looking at the booked orders only in a single value depending on how many orders it has to buy to get the volume needed

11:29 <sacarlson> when you look at the results I think you will get the idea

11:30 <sacarlson> or you could prove me wrong

11:30 <stellar-slack> <meetreks> Can you let me know how to execute your scripts

11:30 <stellar-slack> <meetreks> I use Node JS for mine

11:30 <sacarlson> it's ruby

11:30 <stellar-slack> <meetreks> so I go to ruby and execute that code?

11:30 <sacarlson> do you run on linux?

11:31 <stellar-slack> <meetreks> NO

11:31 <stellar-slack> <meetreks> Windows

11:31 <sacarlson> then I'm not sure, my code was developed on linux. ruby is cross platform but I've never run my code on windows

11:32 <stellar-slack> <meetreks> let me try ruby

11:32 <stellar-slack> <meetreks> you might have to guide me

11:33 <sacarlson> sure I would love to know if my code runs on windows since at some point I do plan to port it

11:34 <stellar-slack> <meetreks> OK

11:34 <stellar-slack> <meetreks> I am in ruby

11:34 <stellar-slack> <meetreks> what next

11:34 <sacarlson> then you will want to download my git

11:35 <sacarlson> https://github.com/sacarlson/pokerth_accounting

11:35 <stellar-slack> <meetreks> like npm install and the link?

11:35 <sacarlson> there is a download botton https://github.com/sacarlson/pokerth_accounting/archive/master.zip

11:36 <sacarlson> after you have the files uncompressed in a directory you will need to install some gem stuf

11:36 <stellar-slack> <meetreks> I have gems already

11:36 <sacarlson> that's the part I'm unsure of in windows

11:36 <sacarlson> oh ok

11:37 <stellar-slack> <meetreks> how do I run?

11:37 <sacarlson> so how would you get sqlite3 ruby-sqlite3 support?

11:38 <sacarlson> on linux we just sudo apt-get install ruby-full sqlite3 ruby-sqlite3

11:39 <stellar-slack> <meetreks> I have everything sacarlson

11:39 <stellar-slack> <meetreks> I now have your files uncompressed

11:39 <sacarlson> oh then gem install rest-client

11:39 <sacarlson> gem install json

11:39 <stellar-slack> <meetreks> I have Json

11:40 <stellar-slack> <meetreks> I have rest-client as well

11:40 <sacarlson> ok

11:40 <sacarlson> so we need to create some accounts

11:40 <stellar-slack> <meetreks> right

11:40 <stellar-slack> <meetreks> how do we do that?

11:41 <stellar-slack> <meetreks> use Stellar BOT itself

11:41 <sacarlson> well I guess if all the parts are installed you could just cd to the directory and run pokerth_accounting.rb

11:41 <sacarlson> that would auto create an account

11:42 <sacarlson> my software in theory would also fund the account for you

11:42 <stellar-slack> <meetreks> ok

11:42 <stellar-slack> <meetreks> let me try

11:42 <stellar-slack> <meetreks> just for saftey i tried json

11:42 <stellar-slack> <meetreks> it is taking a while

11:43 <stellar-slack> <meetreks> ok done

11:43 <sacarlson> you will also want a sqlite browser do they have one on windows?

11:43 <stellar-slack> <meetreks> Yes :)

11:44 <sacarlson> well I don't see account number sent to http://poker.surething.biz/ so something didn't work

11:45 <stellar-slack> <meetreks> Well

11:45 <stellar-slack> <meetreks> I ran it

11:45 <stellar-slack> <meetreks> it asked me to open your rb fil

11:45 <sacarlson> so any output on the console?

11:45 <stellar-slack> <meetreks> i chose IE

11:45 <stellar-slack> <meetreks> and i just gives me the full source code

11:45 <stellar-slack> <meetreks> nope

11:45 <stellar-slack> <meetreks> nothing on th console

11:46 <sacarlson> I would assume in a console you would type ruby ./pokerth_accounting.rb to get the interpreter to run it

11:47 <stellar-slack> <meetreks> in windows

11:47 <stellar-slack> <meetreks> it is ruby pokerth_accounting.rb

11:47 <sacarlson> in your command window

11:48 <stellar-slack> <meetreks> yes

11:48 <stellar-slack> <meetreks> now getting proper error

11:48 <sacarlson> you should see errors output if you don't have the gems installed

11:48 <stellar-slack> <meetreks> I have gems

11:48 <sacarlson> errors being what?

11:49 <stellar-slack> <meetreks> 'require' cannot load such file -- sys/proctable <Loaderror >

11:49 <sacarlson> gem install rest-client

11:49 <stellar-slack> <meetreks> I did

11:50 <stellar-slack> <meetreks> and it sucessfully installed

11:50 <sacarlson> ok we can comment out the sys/proctable we won't need it for what you want

11:50 <sacarlson> oh maybe we can install that too?

11:51 <stellar-slack> <meetreks> how

11:51 <stellar-slack> <meetreks> gem install ??

11:51 <sacarlson> gem install sys-proctable

11:52 <stellar-slack> <meetreks> ok got it

11:52 <sacarlson> ok

11:52 <stellar-slack> <meetreks> now

11:53 <sacarlson> ruby ./pokerth_accounting.rb and see what other error we see

11:53 <stellar-slack> <meetreks> modir: no such file or directory

11:53 <stellar-slack> <meetreks> C:/userrs/user2/ ...

11:53 <stellar-slack> <meetreks> ENOENT

11:54 <sacarlson> oh these paths won't work in windows ~/.pokerth/log-files/

11:55 <stellar-slack> <meetreks> so what whould I remove?

11:55 <sacarlson> so I would have to change them to something windows would use

11:55 <sacarlson> what was this C:/userrs/user2/ ?

11:56 <sacarlson> was that in the error ?

11:56 <stellar-slack> <meetreks> Yes

11:56 <stellar-slack> <meetreks> Guess

11:56 <stellar-slack> <meetreks> it is trying to log it in windows defautl

11:56 <sacarlson> so do those dir exist?

11:57 <sacarlson> I guess at this point you will have to pick a directory maybe a subdir of where you uncompressed it

11:58 <sacarlson> that you would have to create then modify the lines 12 and 13 to point at them

12:00 <sacarlson> another option is run everything on linux mint in a virtualbox running on your windows

12:01 <stellar-slack> <meetreks> guess gem install sqllite3

12:01 <stellar-slack> <meetreks> I changed the logs path

12:01 <stellar-slack> <meetreks> now I get SQL exception :)

12:01 <sacarlson> what line is that pointing at?

12:02 <sacarlson> you did install sqlite3?

12:02 <stellar-slack> <meetreks> just giving this now...to be usre

12:03 <stellar-slack> <meetreks> gem install sqlite3

12:03 <sacarlson> yes you will need that

12:03 <stellar-slack> <meetreks> very quickly it has done that

12:03 <stellar-slack> <meetreks> again

12:03 <stellar-slack> <meetreks> OK

12:03 <stellar-slack> <meetreks> I get these things

12:04 <stellar-slack> <meetreks> last log filename = accountlog.pdb

12:04 <stellar-slack> <meetreks> got here not exist

12:04 <stellar-slack> <meetreks> Exception occured in configs

12:04 <stellar-slack> <meetreks> no such table : Player

12:05 <stellar-slack> <meetreks> Guess it is an SQL exception

12:05 <stellar-slack> <meetreks> looking for table Player

12:05 <stellar-slack> <meetreks> but cant find the schema

12:06 <sacarlson> if it didn't exist it was supposed to create it

12:07 <stellar-slack> <meetreks> Hmm

12:07 <sacarlson> oh at this point it is looking for log files generated by pokerth

12:08 <stellar-slack> <meetreks> Yes

12:08 <stellar-slack> <meetreks> any suggestions

12:08 <sacarlson> well for the full package you could install pokerth there is a windows version but..

12:09 <sacarlson> you just want the tools so maybe they will already work

12:09 <stellar-slack> <meetreks> OK

12:10 <stellar-slack> <meetreks> send me that

12:10 <sacarlson> try run ruby check_account.rb

12:10 <stellar-slack> <meetreks> ok

12:10 <sacarlson> I think we won't need it for what you want

12:10 <sacarlson> we will just use the payment class at this point

12:11 <stellar-slack> <meetreks> That is running fine

12:11 <sacarlson> cool

12:11 <stellar-slack> <meetreks> I use nodejs

12:11 <sacarlson> so all we really need is an account number set then or 2

12:11 <stellar-slack> <meetreks> this rubs is so diffent

12:11 <stellar-slack> <meetreks> what is this ruby by the way?

12:12 <sacarlson> ruby it's just an interpreted object oriented language

12:12 <sacarlson> I prefer it's simplicity

12:12 <stellar-slack> <meetreks> does the same as node JS

12:12 <stellar-slack> <meetreks> node JS is also simple

12:13 <stellar-slack> <meetreks> can you send me a link to learn ruby?

12:13 <sacarlson> I guess they are all simple if you know them

12:13 <stellar-slack> <meetreks> :)

12:13 <stellar-slack> <meetreks> Yes

12:13 <sacarlson> the example code is the best

12:13 <stellar-slack> <meetreks> OK

12:13 <stellar-slack> <meetreks> will try and follow it

12:14 <stellar-slack> <meetreks> so now what is the step?

12:14 <sacarlson> so all we would have to do to get send_currency.rb to create your accounts would be to add your accounts numbers in the code

12:15 <stellar-slack> <meetreks> which code sacarlson

12:15 <stellar-slack> <meetreks> send_currency.rb?

12:15 <sacarlson> change the #from_pair = {"account"=>"gLan...","secret"=>"s3zD..."} and #to_pair = {"account"=>"gKzt...","secret"=>"sfyq..."}

12:15 <sacarlson> to your accounts

12:16 <sacarlson> yes that's what creates accounts with trust

12:17 <sacarlson> run it two times with a different to_pair the secound time and you will have two accounts with all the currencys

12:17 <sacarlson> you will also have to take out the # commented lines to enable them again

12:18 <stellar-slack> <meetreks> OK

12:18 <stellar-slack> <meetreks> for a start

12:18 <sacarlson> with those account you can then setup orders between them with your JS or other

12:19 <stellar-slack> <meetreks> can you share any accounts and keys

12:19 <sacarlson> don't you have any?

12:19 <sacarlson> you can get them from the faucet

12:19 <stellar-slack> <meetreks> link?

12:20 <sacarlson> https://www.stellar.org/ scroll down to start tutorial

12:21 <sacarlson> it will generate account pairs and deposit 1000 STR in them for you

12:22 <stellar-slack> <meetreks> I have

12:22 <stellar-slack> <meetreks> gpHUkTY9c7qviqSbAkPMm5v9ZyTDho9GAE sf2GCNjmvf5Ng8Dak4bAmuYqYBk9hkZuFqMMQiLYdEf3BRMX1GW

12:23 <stellar-slack> <meetreks> gBuYT5AQpjw1mEiDBJNJshtV3GyV5A2UKA s3wXzQDc638s3dYrrfJbF1nNQSsUW1JATBinLGb8VjQuaXiay3F

12:23 <sacarlson> I have a function in my class_payment.rb that creates new accounts with funding but you need one account with funding to create more

12:23 <sacarlson> ok

12:23 <stellar-slack> <meetreks> and it has deposited money

12:23 <sacarlson> yup

12:24 <stellar-slack> <meetreks> not sure with the syntax

12:24 <stellar-slack> <meetreks> so

12:24 <stellar-slack> <meetreks> uncommented

12:24 <stellar-slack> <meetreks> from_pair = {"account" : "gpHUkTY9c7qviqSbAkPMm5v9ZyTDho9GAE"

12:24 <stellar-slack> <meetreks> like that

12:24 <stellar-slack> <meetreks> or any other formats?

12:25 pixelbeat_ has joined #stellar-dev

12:25 <sacarlson> from_pair = {"account"=>"gpHUkTY9c7qviqSbAkPMm5v9ZyTDho9GAE", "secret"=>"sf2GCNjmvf5Ng8Dak4bAmuYqYBk9hkZuFqMMQiLYdEf3BRMX1GW"}

12:26 <sacarlson> put it bellow he YAML

12:26 <sacarlson> the yaml is used to import the secreet numbers from a sucured file

12:29 <stellar-slack> <meetreks> guess it went to sleep mode

12:29 <stellar-slack> <meetreks> guess the function itself worked

12:29 <stellar-slack> <meetreks> but check balance failed

12:30 <stellar-slack> <meetreks> shouldnt matter i guess

12:30 <stellar-slack> <meetreks> let me try with another set of pair

12:31 <sacarlson> I'm not sure you put the from_pair and to_pair in the correct location . I see that the names are used bellow the Yaml that could be replaced with yours

12:31 <sacarlson> or I have the numbers what am I thinking I could run them

12:31 <sacarlson> or = oh

12:34 <stellar-slack> <meetreks> I did

12:34 <stellar-slack> <meetreks> Ok

12:35 <stellar-slack> <meetreks> ran it for 2 different pairs

12:35 <stellar-slack> <meetreks> what is the next step?

12:37 <sacarlson> next step check the ballance

12:37 <sacarlson> I'm also running it on the first set that is sending 10,000 to each currency

12:38 <stellar-slack> <meetreks> OK

12:38 <sacarlson> just change the ammount and run it again to get more money

12:39 <sacarlson> so for your orders and payment transaction you will us the from_pair account as the issure

12:40 <sacarlson> opps you will need a 3rd set of account numbers

12:41 <sacarlson> the to_pair will be changed but the from_pair will stay the same

12:41 <sacarlson> your from_pair will be your primary issuer

12:51 <sacarlson> I looked at the account ballance of "gBuYT5AQpjw1mEiDBJNJshtV3GyV5A2UKA" and I note that it only has trust set for CHP, seems I failed to put the delay in the first one that makes the others not work

12:52 pixelbeat_ has quit [Ping timeout: 250 seconds]

12:56 <sacarlson> even with the added delay and running it again I still only see AUS, USD, CHP with positive ballances, maybe I need to add delays between the add trust?

13:09 <sacarlson> after adding a 12 second delay between each add trust it seems to have worked for the rest of the currenies

13:11 <sacarlson> "gBuYT5AQpjw1mEiDBJNJshtV3GyV5A2UKA" now has all these USD EUR JPN AUS GBP CHP from the issuer "gpHUkTY9c7qviqSbAkPMm5v9ZyTDho9GAE" with minimum 10k each
