Terminal inside of termux ubuntu. Tailing the debug.log then starting Kronos with npm start.  Cool



So sick  Cool Cool Cool Cool

Did you do any updates to Termux in general for it in your repo?

I don't get why that screenshot is gigantic. Below is all contained on mobile phone, full blockchain daemon.

Maybe someone will find this useful to mess around in python 3. Signs a bitcoin tx without pulling in the bitcoin module, haven't come across anywhere doing the whole thing in 3 from the very basics. Looking to switch this over to sign a Denarius tx. Commented as much as I could from different examples, and also where I know things need to change.

Code:
import struct
import base58
import hashlib
import ecdsa
import codecs
import binascii
from hashlib import sha256

On a heavily abused wallet.dat sometimes things become glitchy. So I came up with a script to dumpwallet to a text file, export addresses with a balance and match up against the dumpwallet, and create a cleaned.txt file of only addresses with a balance to importwallet into a brand new wallet.dat. My most glitchy wallet.dat was brought down from 154mb to 16mb, and ran very smooth. Like usual backup wallet.dat to a safe location before messing around with anything. Hope it helps someone, should be usable on any Bitcoin fork.

Great script and very clear and detailed instructions in the bash file (that part of unplugging internet while dumping to avoid being hacked is a nice reminder, thanks)
Great work, buzzkillb  Smiley

​Since I do think this is useful to someone curious about touching an electrumx server, crossposted below.

Been wondering how to make use of the electrumx server, but in bash. First I needed to connect to the electrumx server.

Code:
#!/bin/bash
echo "get block header"
(echo '{"method" : "blockchain.block.header", "params": ["1"], "id": "msg_id"}'; sleep 1) | ncat --ssl electrumx1.denarius.pro 50002

This outputs.

Code:
block header
{"jsonrpc": "2.0", "result": "06000000cd8f82c4c28201fd89def0dba541d66432bff9c1bb16fc1c6201dabb5d0d0000e4abd1522f390c5a2b83add7c8d29b875e1e0691dc43267f0406e9ddfea329c76ab74159ffff0f1e000d8425", "id": "msg_id"}

So now to get a balance. The thing with electrumx server is that you need a scripthash to call any address functions. But I don't have that. All I have is a bash terminal and a Denarius address. So what do I do? Line by line dissect how people create an address and then work backwards to the scripthash.

I need this image, but down to up. source: https://learnmeabitcoin.com/guide/p2pkh



 

This is not so easy as I can't find anyone doing this backwards in bash. But I found lots of posts how to go forwards.

Here is how to get it before converting to big endian.

Code:
#!/bin/bash
. denarius.sh

#DUP HASH160
begin="76A914"
echo $begin
#EQUALVERIFY CHECKSIG
end="88AC"
echo $end

echo "decodeBase58"
decoded="$(decodeBase58 DCMRvR6MUppPgP8vrMKuni4FL5de8SjicG)"

echo "Remove 00 bytes"
echo ${decoded#??}
removefront=$(echo "${decoded#??}")
echo $removefront

echo "Remove checksum"
removeback=$(echo "${removefront%????????}")
echo "95 characters base58"
echo $removeback


echo "now what?"
echo $begin$removeback$end
echo "convert to scripthash"

echo -n $begin$removeback$end | xxd -r -p | sha256sum | cut -d' ' -f1
scripthash=$(echo -n $begin$removeback$end | xxd -r -p | sha256sum | cut -d' ' -f1)
echo $scripthash

Will also need grondilu bitcoin-bash-tools. https://github.com/grondilu/bitcoin-bash-tools Get the bitcoin.sh and throw that into the same directory you are going to test this out in, for obvious reasons I renamed bitcoin.sh to denarius.sh.

First I am assuming a standard P2PKH address with OP_DUP OP_HASH160 hashedpublickey OP_EQUALVERIFY OP_CHECKSIG



Code:
#DUP HASH160
begin="76A914"
echo $begin
#EQUALVERIFY CHECKSIG
end="88AC"
echo $end
Then decodeBase58 of our Denarius address, works on bitcoin obviously.



Code:
echo "decodeBase58"
decoded="$(decodeBase58 DCMRvR6MUppPgP8vrMKuni4FL5de8SjicG)"
Then remove 00 bytes from the front of this. The #?? removes 2 characters from the left of a string.



Code:
echo "Remove 00 bytes"
echo ${decoded#??}
removefront=$(echo "${decoded#??}")
echo $removefront
Now remove the checksum. The %?HuhHuh? removes 8 characters from the right of the string.



Code:
echo "Remove checksum"
removeback=$(echo "${removefront%????????}")
echo "95 characters base58"
echo $removeback
Now what? How to convert to scripthash? We can echo the the uncompressed public key, kind of.

Code:
echo "now what?"
echo $begin$removeback$end
echo "convert to scripthash"
sha256 this in proper format, using xxd and then sha256 that.

Code:
echo -n $begin$removeback$end | xxd -r -p | sha256sum | cut -d' ' -f1
scripthash=$(echo -n $begin$removeback$end | xxd -r -p | sha256sum | cut -d' ' -f1)
echo $scripthash
At the end from that address I get.

Code:
3735fe8239322122222f8a8f42d9b6545bc517e2086116e57953fdc9cc7f6115
For now I have a separate function I found to convert to big endian, since electrumx server wants it this way.
source: https://electrumx.readthedocs.io/en/latest/protocol-basics.html#script-hashes

Code:
#!/bin/bash

#echo 6191c3b590bfcfa0475e877c302da1e323497acf3b42c08d8fa28e364edf018b | ./bigendian.sh
#8b01df4e368ea28f8dc0423bcf7a4923e3a12d307c875e47a0cfbf90b5c39161

# check stdin
if [ -t 0 ]; then exit; fi

v=`cat /dev/stdin`
i=${#v}

while [ $i -gt 0 ]
do
    i=$[$i-2]
    echo -n ${v:$i:2}
done

echo
I run this like

Code:
echo 3735fe8239322122222f8a8f42d9b6545bc517e2086116e57953fdc9cc7f6115 | ./bigendian.sh
and get the scripthash electrumx server wants

Code:
15617fccc9fd5379e5166108e217c55b54b6d9428f8a2f222221323982fe3537
Like bash magic we can use that scripthash to talk to the electrumx server to get a balance.

Code:
#!/bin/bash
echo "get balance"
(echo '{"method" : "blockchain.scripthash.get_balance", "params": ["15617fccc9fd5379e5166108e217c55b54b6d9428f8a2f222221323982fe3537"], "id": "msg_id"}'; sleep 1) | ncat --ssl electrumx1.denarius.pro 50002
And we get the balance.

Code:
get balance
{"jsonrpc": "2.0", "result": {"confirmed": 125740854, "unconfirmed": 0}, "id": "msg_id"}
And a large step forward in creating a basic terminal wallet for any device that can use bash, ncat and has port 50002 open.

Looks like lots happening over at https://blockforums.org/ , looks like it will be the next "bitcointalk"



Already is as more knowledge is being passed along over there, while this place deletes technical posts. Would you believe my bash script helped someone figure out how to do something with electrumx server?
Even normal posts like "today was a good day" got deleted from me, just got a message about that. I would like to add, fuck you bitcointalk and whoever thinks he's running this place. A big fuck you!

Yes for real hahaha, I got the same, a plethora of my messages were removed, thanking services and others for creating different Denarius related services...

dPi development coming along strongly, Beta will be available soon!

Kind of annoyed so many of my posts are being deleted, and yet they are very related to Denarius and cryptocurrency in general. Anyone else ever show how to basically interact with an electrumx server using bash, including Bitcoin? A bit over the top censorship admin, as you allow the other guy to make fun of other people's sexuality. So talking about cryptocurrency stuff on this forum is a questionable thing, but calling people names and sexual innuendo towards Developers and community is tolerated. I hope this makes sense to someone else.

Makes sense to me, I agree, it is totally not cool nor okay, My post was deleted above for sharing out our new Trello link, which is something extremely related to Denarius and its development and community. They removed the link for "non-related post" which makes absolutely zero sense and is totally not okay. This forum has been going downhill lately...I bet this is one of the reasons why Satoshi doesn't post here anymore.



Moderating out the road map from a cryptocurrency is pretty lame. What happened to the old bitcointalk where people used to post about cool stuff? Or was anything recent just deleted to keep all the troll spam going on?
