1 2018-01-21 00:13:22 <Barrett> so basically to create a bare bone colored coin I can just create a custom CScript
 2 2018-01-21 00:13:38 <Barrett> and use it to encode/decode in my custom client
 3 2018-01-21 01:10:30 <me1> hi
 4 2018-01-21 03:00:57 <mahamoti> does anyone know what the first bitcoin block was that had a real transaction in it?
 5 2018-01-21 03:05:15 <mahamoti> i could find it myself if there was a block explorer that allowed me to lookup a block by its height on the mainchain..
 6 2018-01-21 03:05:52 <mahamoti> in but blockexplorer.com i can only click "next block" which prevents me from doing a binary search
 7 2018-01-21 03:07:24 <mahamoti> oh, I found it...block #181
 8 2018-01-21 03:07:31 <mahamoti> https://blockexplorer.com/block/00000000dc55860c8a29c58d45209318fa9e9dc2c1833a7226d86bc465afc6e5
 9 2018-01-21 03:10:42 <mahamoti> this is actually really confusing, because in all previous blocks, there has only been 1 transaction (block reward of 50).  however, in block 181 there is a transaction sending 40 from an "unparsed address"
10 2018-01-21 03:11:01 <mahamoti> how can there be an unparsed address that only contains 40 btc, if all previous transactions were sending 50 btc to unique addresses
11 2018-01-21 05:06:47 <arubi> mahamoti, block 170 is the first.  the transaction in 181 redeems 40 btc from the output that paid to it in block 170
12 2018-01-21 05:08:26 <arubi> not sure about the "unparsed" part.  you can use smartbit, it's a much better explorer https://www.smartbit.com.au/block/170
13 2018-01-21 05:22:38 <arubi> oh also, these transactions aren't really using p2pkh.  they're using p2pk, so the addresses there are actually wrong
14 2018-01-21 05:54:50 <Randolf> arubi:  That's a lot faster than blockchain.info.  I like it.
15 2018-01-21 14:38:47 <lopp> hi all, I'm looking to collect more links to add to the developer tools section of http://lopp.net/bitcoin.html - are there any you recommend that aren't already listed there or on https://github.com/igorbarinov/awesome-bitcoin ?
16 2018-01-21 18:10:03 <Randolf> lopp:  If it's helpful, please feel free to add a link to this article I wrote last month, which outlines two important rules for handling Private Keys (perhaps it's helpful to open source wallet software developers who want their software to have elements of integrity so as to be "trusted"):
17 2018-01-21 18:10:54 <arubi> the link is cut off Randolf

19 2018-01-21 20:45:50 <pincode> Hi,Folks! I have some questions about bitcoin dev. I develop web application and I want to understand how to generate bitcoin wallets for users and manage it?
20 2018-01-21 20:46:42 <pincode> I have an idea use blockchain.info api for it, but I think I can use it on my side without third-party api, can you explain how can I do this?
21 2018-01-21 20:47:40 <pincode> Hey, can you help me anybody?
22 2018-01-21 21:01:26 <Randolf> Why rely on a dubious third party like BlockChain.info when you can just run your own node and query that directly?
23 2018-01-21 21:03:01 <pincode> How many gigabytes I need for storing full-node on my server for btc as an example?
24 2018-01-21 22:31:56 <Randolf> Present, Bitcoin is approx. 500 MBs (0.5 GBs).  But that's expected to continue to grow over time.
25 2018-01-21 22:32:24 <Randolf> So, you'll probably want to provision at least 1 or 2 TBs.  Given the low cost of disk space, I'd get 2 TBs now.
26 2018-01-21 22:38:15 <contrapumpkin> Randolf: 500MB?
27 2018-01-21 22:58:44 <Randolf> Sorry, less than 200 MBs.  I did that from memory and thought wrongly.
28 2018-01-21 22:59:03 <Randolf> But none-the-less, preferring a 2 TB hard drive will likely be a benefit for you anyway.
29 2018-01-21 23:02:21 <contrapumpkin> Randolf: I'm still confused. The blocks for my full node are somewhere between 150GB and 200
30 2018-01-21 23:08:08 <Randolf> All the data that your Bitcoin node needs to store is somewhre in the ballpark of 158 GBs to 200 GBs.
31 2018-01-21 23:08:25 <Randolf> For your project, you'll want to stay away from pruning.
32 2018-01-21 23:08:30 <contrapumpkin> oh, you talking about RAM usage for the UTXOs?
33 2018-01-21 23:08:37 <Randolf> Disk space.
34 2018-01-21 23:08:44 <Randolf> That's why I'm talking about hard drives.
35 2018-01-21 23:08:52 <contrapumpkin> yeah but you're also saying 500MB
36 2018-01-21 23:09:10 <Randolf> So?  I specified disk space.
37 2018-01-21 23:10:56 <Randolf> In your question, you didn't specify whether you were asking about RAM or disk space, so I assumed disk space because that's what people are usually referring to when they don't specify RAM.
38 2018-01-21 23:11:19 <contrapumpkin> [16:03:00]  <pincode>	How many gigabytes I need for storing full-node on my server for btc as an example?
39 2018-01-21 23:11:29 <contrapumpkin> that's not my question
40 2018-01-21 23:12:14 <contrapumpkin> and the answer is in the ballpark of 170GB
41 2018-01-21 23:12:17 <Randolf> Oh, that's right.  I wasn't paying attention to the handles.  Thank you.  However, I still assumed the discussion was about disk space.
42 2018-01-21 23:12:36 <Randolf> So, are you thinking that you need 170 GBs of disk space, or 170 GBs of RAM?
43 2018-01-21 23:12:43 <contrapumpkin> 170GB of disk space
44 2018-01-21 23:12:50 <Randolf> At this time, I agree.
45 2018-01-21 23:12:51 <contrapumpkin> today
46 2018-01-21 23:12:54 <contrapumpkin> yes
47 2018-01-21 23:12:59 <contrapumpkin> so I don't understand what your 500MB was measuring above
48 2018-01-21 23:13:12 <Randolf> I haven't run my copy of bitcoind recently, so I didn't know the exact size.
49 2018-01-21 23:13:46 <Randolf> I already clarified that:  [14:58:42] <Randolf> Sorry, less than 200 MBs.  I did that from memory and thought wrongly.
50 2018-01-21 23:14:05 <Randolf> So, if you want to argue about 500 MBs, I won't be participating.
51 2018-01-21 23:14:27 <contrapumpkin> not arguing, just trying to understand
52 2018-01-21 23:14:36 <Randolf> Okay.  Well, I clarified already.
53 2018-01-21 23:14:37 <contrapumpkin> because your correction after that was again in MB, rather than GB
54 2018-01-21 23:14:56 <Randolf> Yeah, thanks.  I meant GBs.
55 2018-01-21 23:14:59 <contrapumpkin> okay cool
56 2018-01-21 23:15:01 <Randolf> I'm not feeling well today.
57 2018-01-21 23:15:08 <contrapumpkin> didn't mean to be argumentative, was just trying to figure out if I was missing somehting
58 2018-01-21 23:15:12 <Randolf> Kids were sick all day yestreday, and a bit the day before.
59 2018-01-21 23:15:22 <Randolf> Sorry, I'm just a bit touchy because I was dealing with idiots in a different channel.
60 2018-01-21 23:15:29 <Randolf> You're being clear, and I appreciate that.
61 2018-01-21 23:15:49 <Randolf> Wow, what a disaster.  Sorry about the confusion.
62 2018-01-21 23:15:58 <Randolf> ...and thanks, contrapumpkin, for catching this.
63 2018-01-21 23:16:04 <Randolf> contrapumpkin++
