Testnet 3 is pretty much deprecated and replaced with v4. Any particular reason why you need v3 specifically ?

Just to clarify myself. I don't search after paid devs or freelancers.

This is gold, you expect a developer to work for free?  Roll Eyes
Soioper seekrit project and you prolly make moon promises with no guarantees. No different than the hundreds of other "idea guys" I deal with on a near daily basis.

The actual link is https://github.com/0xMouiz/python-secp256k1 but not very useful - appears to be geared towards mETH addicts.

As previous poster said, most all implementations are just wrappers over the C library and this is trivial to do.

Re: base58encode_check to a string

Perhaps something like

Code:
from sys import stdin
from pybitcointools import privkey_to_pubkey, pubkey_to_address
from hashlib import sha256

print pubkey_to_address(privkey_to_pubkey(sha256(stdin.read()).hexdigest()))

Hash yer string with sha256, this is the private key which then spits out a public key you can send dust to, etc.

Re: [MOON] Mooncoin 🌙 built in 2013 with the future in mind

Hi Moon Bro, we hope to find a good dev for Mooncoin in 2025 (suggestions are welcome)

Hi, I recently rediscovered a <i>ten year old</i> mooncoin wallet I had lying around, I mined them with a friend way back in the day.

I tried compiling the most recent mooncoin core release, and after some fighting *did* get the cli parts to build on modern linux. The QT is in very rough shape however and needs a total overhaul. Am willing to dedicate some time to this if you guys are hiring a developer. Tongue

Re: Why is it empty when sending rpc via curl?

Why is it empty when sending rpc via curl?
Code:
curl --user x:x --data-binary '{"jsonrpc":"1.0","id":"curltest","method":"getrpcinfo","params":[]}' -H 'content-type:text/plain;' http://95.216.35.227:8332/

Either 1) The listed IP does not have the RPC port exposed, or 2) You are trying to do this to your own node from within NAT.

Re: [ANN] [BSV] [Bitcoin SV] Original Satoshi Vision

To be honest, I don't see future for BSV - positions are getting lower and lower, capitalization is not growing, and it is not visible, due to which progress can be made
We are very sorry for that. We can't hide it anymore, things really went wrong.

We thank everyone who supported us. We tried our best to develop an unique project, but global crypto-community was not on our side

Please forgive us if you can





How about No. Get rekt.

This sounds interesting, I like building custom linux kernels and hardware engineering in general. Do you have a Telegram ID?

The project your skills would be used for is Bitcoin Eco. We have a Discord. Very new.. Announced yesterday. The official ANN is in my signature . Looking forward to seeing your skill set.

Oh I see this is a Proof-Of-Stake "Bitcoin killer" project, so actually don't think I'm interested.  Cheesy

Nope not a Bitcoin Killer. Evolve Bitcoin. You really don't have to like the project to work on its tools. its a paying gig. No worries. The pay is in BTC if you are worried  Cheesy Wink

BTC always best for things of this nature, even as is.

Why PoS? Sure I'll build ya some custom arm kernels, and love running small boards via solar. But consensus algorithm change is hefty.

Praise "BOB" ... XBLOCK mined successfully. Anyone having issues welcome to contact me on Telegram or irc.

"BOB" Bless Shinoa-Fores : AN UPDATE IS UPON US

v10.2.0 Hardfork @ block 951753
Currently: 951386

Shit, I can't recall what the fuck its doing..
I think we're switching from HALVING every 4 years
to just making 2.5 BOB per block FOREVER

Just *nix Wallets right now,
but he's almost ready with the Windows and Android wallets.

HARD FORK, means your existing wallet will no longer be compatible.. so you'll have to back up the wallets.dat and drop it over the fresh install if you want to move your Slack. Feel free to drop by http://subgenius.finance for assistance. Lotta crypto shit goin on over there.

1% pool fee
stratum: -a sha256 -o stratum+tcp://stratum.cryptohamstr.com:3333 -u ADDR -p c=UNO

You can use c=UNO,d=X in order to change your miners difficulty.

Have fun mining.

Very nice! Will mine a few test blocks, though I have not enough hash to compete.  Cheesy

I can not believe this coin has been able to remain the hidden gem it is.   

It's going straight past Proxima Centauri, just a matter of time.  Once crypto education is added to school curriculums the crypto illiterate will find it.

It's one of the few coins that has a shot at overtaking Btc in price per unit IMO

Just wanted to thank the devs for staying true to it's original vision.

We try to have users be appreciative of the rare asset they hold and share curriculum on blog, like http://unobtanium.uno/blog/bash-unobtanium-tools-generating-an-uno-address-offline-with-diceware.html

Re: Brute-forcing Bitcoin private keys

on 03/03/2021, 16:28:32 UTC
never heard of this website, but it's proof of exactly what i said which is they found 19321 private keys in 50771 Bitcoin addresses with transactions. just for bitcoin addresses so to people who say it's not possible here is a good proof that it is possible and can be done with a large enough of group with good machines with some luck

It's proof that brainwallet and private key chosen by human/generated with weak RNG are vulnerable towards brute-force attack and few other attack (such as dictionary attack for brainwallet).

Precisely this. OP may find http://www.loper-os.org/bad-at-entropy/manmach.html interesting if he wishes to see just how bad humans are at entropy.

Well I don't want to really impose on another person(s) project. If you have any advertising materials on it we could set some stuff up for that, as far as miners there are lots of them on discord with pools etc etc.. also the costs or what is needed would be and could be figured out by you, if your or someone else is still interested. If you could come up with a comprehensive list of what is needed and post it here I'm sure we would appreciate it so maybe we can have a better understanding of what we need to start it up.

I'd suggest to make a Prototanium revival thread for this then, as this is the Unobtanium thread and discussion is quickly becoming off-topic.

As far as "imposing" on someone else's project, it's ded for all intents and purposes, but still remains an open-source project, so anyone can do as they wish with it. I maintained my own UNO client for years before joining up as a project developer.

As a freelance developer, I welcome PM's from folks interested in my paid[/b] services for select projects. As I recall, you had no funding for the project and I simply cannot do any unpaid work at this time. I wish you well on the project if you do decide to organize a revival.

Well if you guys are in discord you can come and join and chat in here https://discord.gg/JjuRJPn I don't know about telegram all too much but you can find people interested in projects and some miners on there.

I recall joining this channel the last time there was interest in reviving Prototanium, but you were uninterested in funding the development of the project. If you have miners available in that chan then they are welcome to try and restart the Pr chain from the Github linked above. But as it stands now, I will be resetting testnet3 with the next release of UNO and cut off the dead weight.

Re: Brute-forcing Bitcoin private keys

Since 2^256 is likely a number larger than the number an atoms in the known universe, better get to crackin' with that abacus or wait for the advent of quantum computers if/when machines capable of doing this come to exist in our lifetimes.
2256 is not the number of the addresses. Even if you brute force private keys, that are around 2256, you want to find a collision, not necessarily someone's private key. A RIPEMD-160 hash (which is the address decoded) is 160-bits long, which means 2160. So you're brute forcing this number:

1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976

Since private keys are ~2256 and all possible combinations of addresses 2160, then you're trying to find one of the ~296 private keys that collide with the same address. So next time you create an address, keep in mind that besides your private key, there are around 79,228,162,514,264,337,593,543,950,335 more.


I never said this was number of addresses. Plenty of tools exist to find collisions, though OP strikes me as the type that would be more interesting in playing the lottery and bashing up something to search https://allprivatekeys.com/ or something.

never heard of this website, but it's proof of exactly what i said which is they found 19321 private keys in 50771 Bitcoin addresses with transactions. just for bitcoin addresses so to people who say it's not possible here is a good proof that it is possible and can be done with a large enough of group with good machines with some luck

The addresses on that site *could* be - as has already been mentioned in this thread - collisions and NOT keys that were simply cracked by brute force ya know.  Cheesy
