I've failed to receive topic reply email notifications since mid-August. I think Yahoo! Mail classified them as spam, but not anymore. If you'd like a reply to a post in the last six months, please repost it or PM me. Sorry for the trouble. (It's been years since I evaluated free spam filters... perhaps I should again?)

I am working on an CASHCoin Abe, seems didn't work. Is that something wrong?

http://115.29.51.156:7000/

When Abe loads a chain into the database but shows only the genesis block, the chain probably computes hashPrev using an algorithm other than double-SHA256. NovaCoin does this, and I recently added support for it (thanks to Drak's sponsorship). However, there is not yet a generic way to specify this property. It will take some code changes.

I have set up Abe and it's now indexing all the transactions into a PostgreSQL database. Would it be easy to query the database for e.g. the top 10 largest unspent outputs?

I know SQL but I don't know the details of the Abe schema yet, that's where I'm looking for some guidance.

Hello everyone,

after a long while I'm back using abe. Want to make a blockexplorer for Auroracoin.

I configured like this initially (copied from litecoin):

Code:

datadir += [{
 "dirname" : "/home/aur/.AuroraCoin",
 "chain" : "AuroraCoin",
 "code3" : "AUR",
 "address_version" : "u0030",
 "magic" : "u00fcu00c1u00b7u00dc"
}]

~~Problem is addresses have wrong format, like this~~

Code:

6KZU2wRn17sLrxNryFK6CG8KUvBdpArbD8QxwHDW

~~instead of like this:~~

Code:

AL8vRddTujqaFJQ3feZpg1jYHz6Jv2Rkwc

~~I'm pretty sure the magic is correct. From auroracoin sources, main.cpp:~~

Code:

        pchMessageStart[0] = 0xfc;
        pchMessageStart[1] = 0xc1;
        pchMessageStart[2] = 0xb7;
        pchMessageStart[3] = 0xdc;

So the "magic" is correct, right?

Don't know what to set address_version to, though. People have been pointing me to base58.h:

Code:

        
PUBKEY_ADDRESS = 23,
SCRIPT_ADDRESS = 5,
PUBKEY_ADDRESS_TEST = 111,
SCRIPT_ADDRESS_TEST = 196,

What value for address_version and magic do I need to use in order for the addresses to start with the correct prefix?

Am I missing something else in the config?

scratch the above, I got it figured out:

Code:

[/datadir += [{
 "dirname" : "/home/aur/.AuroraCoin",
 "chain" : "AuroraCoin",
 "code3" : "AUR",
 "address_version" : "\u0017",
 "magic" : "\u00fb\u00c0\u00b6\u00db"
}

(forgot the slashes before the 'u's in JSON hex encoding (web-pages seem to eat these), needed to subtract one from each magic byte and got the address_versoin wrong (it's 23, not 30 for AUR)

Stupid question, but how do you keep it up to date? Surely there's a better way then having to continuously run it with --no-serve.

I'm trying to set this up for an alt coin and I'm having trouble with the magic.

Can anyone give me some info on how to find this value?

Hello community,

I need your help once.

I try all the time to set up the Abe with the CacheCoin. Only I get it back, unfortunately not.

This is my abe.conf

Code:

dbtype MySQLdb
connect-args {"user":"abe","db":"abe","passwd":"xxxxx"}
port 333
host 84.200.24.190

datadir += [{
  "dirname" : "/root/.cachecoin",
  "chain": "Cachecoin",
  "code3": "CAC",
  "address_version": "u001c",
  "magic": "u00d9u00e6u00e7u00e5"
}]

If I want to make the run now

Code:

python -m Abe.abe --config abe-smc.conf --commit-bytes 100000 --no-serve

If the following error...

Code:

Can someone help me here?

All Scypt Coins I get to run, but that's here so scrypt_jane?

Thank you in advance for your help!

Please forgive my ignorance and other negative qualities: what is the current status of the ABE license, both officially and pragmatically?
It seems that there has been no discussion about it for at least a year. In addition, my brain sadly goes cross-eyed when trying to interpret legalese, therefore I cannot trust my interpretation of AGPL. I think I understand that all will be fine if I make sure I publish all the used and modified code, but I do not understand how far that goes.

Tobey stated once: "Now, it gets a little hairy if you offer a proprietary service based on Abe's tables, and it needs a running Abe to keep those tables up to date." - but what constitutes 'a proprietary service' in this case?

There are a couple altcoins for which I'm running p2pool nodes that I would also like to set up a block explorer for; the nodes collect 0.9% fee, and would benefit from a working block explorer (as it now links to non-existent pages for user addresses). The block explorer would link to the nodes and to the overarching p2pool hub, logo and all. It feels proprietarish, and I feel that I shouldn't go for it as long as I don't properly understand the license. Any insight would be much appreciated!

Again apologies for the idiocy - had I found a LICENSE.interpretationfordummies.txt, I would not have bothered thee

Does Abe work with coins that use transaction messaging?

I'm trying to set this up with SolarCoin and hitting the same "overflowerror: Python int too large to convert to C long" that others seemed to be getting with coins using transaction messaging. Anyone get past that problem yet?

The original Abe UI seems too simple, any fork or branch with good looking? (any fork can show latest X blocks?) Sad

I can only find one fork done for catcoin

then use it, UI is html + template stuff, so you can just port it to your abe.

Before I went to upgrade, I found that Abe had stopped working. My block file just exceeded 1GB in size a couple hours ago which is causing this error:

Quote

Failed to catch up {'blkfile_number': 1, 'dirname': 'C:\\Documents and Settings\
\Jon\\Application Data\\Bitcoin', 'chain_id': None, 'id': 1L, 'blkfile_offset':
0}

self.input = mmap.mmap(file.fileno(), 0, access=mmap.ACCESS_READ)
WindowsError: [Error 8] Not enough storage is available to process this command

It is because I'm running a 32-bit system. Apparently this issue will eventually affect Linux 32-bit systems as well because of the way mmap works; except that it will occur when the block file hits 2 or 3 GB in size. Is Abe particularly tied to mmap? If it is, it seems like it will soon be (or is now) for 64 bit systems only.

For those who try to use Abe and encounter this error, upgrading from 32-bit Python to 64-bit Python (on a 64-bit system) solves this problem.
