1  Bitcoin / Legal / Bitcoin being deemed an Illegal tender- What's the potential aftermath and uses? on: March 27, 2018, 03:25:29 PM
Regulations for Bitcoin provide some form of relief to cryptocurrency users within a particular jurisdiction or a nation when it has been decided that use of cryptocurrencies, although monitored and the exchanges controlled, can continue to happen among parties that are interested in it. This infact allows stores and people to accept them without being in constant fears of any legal pressures, but when a country deems Bitcoin and cryptocurrencies in general as an illegal tender, it makes me ponder on what possible uses could the dreaded investors and users derive out of their Bitcoins? Would they continue to find value in exchanging cryptocurrencies (its non intended purpose), like trading it similar to a stock / derivative or like currencies being traded in a forex exchange to seek profitable margins?

I'm sure most of you might have a hint of the country that I'm talking about and which has, atleast temporarily, deemed using cryptocurrencies as a medium of exchange / legal tender, illegal. In India, the Minister of Corporate Affairs had read out these lines on public television when he was asked about the 'legal status' of Bitcoins and cryptocurrencies in general. I also remember readinghere that the Ministry of Finance had outrightly stated cryptocurrencies as ponzi scheems and that they are neither currencies nor coins.

Now, it's pretty much possible that many other nations could follow suit and take a similar approach towards Bitcoins. My real concern and the thing that leads to me asking my question is, if they're no longer a legal tender, how would Bitcoin and "cryptocurrencies" in general be used for their original purpose? (considering that loopholes aren't being used, as I'm aware that there's one being utilized at the moment, but could be outlawed soon perhaps?) Most investors would hence prefer to only trade them on an exchange for any value that they find out of it (the value here being the price).

What do you think are its potential aftermath and uses if your country is on the verge to deeming it as an illegal tender? Would you be concerned about no longer being able to use Bitcoins for its intended purpose, i.e; To no longer rely on your Banks and to be your own bank?
2  Bitcoin / Electrum / How to use the 'Revealer' plugin in Electrum 3.1? on: March 07, 2018, 05:24:17 PM
Hi All,

It's the first time I came accross the 'Revealer' plugin and I couldn't find a documentation about it and how exactly does it allow me to create an "Analog multi-factor backup" of my seed. Is anyone aware on how this functionality works and what it does to help store my seed as I can't seem to understand what an analog multi-factor backup means.





And on visiting https://revealer.info (with and without the https) it doesn't seem to load the page. Maybe their page is down at the moment?

Also when I click on "Calibrate" and then click on "Print Calibration pdf" it leads me to an Electrum error - (Could someone try this out and let me know if they face the same issue?)



Thank you for your time.
3  Bitcoin / Bitcoin Technical Support / Questions on - Signature aggregation and Lightning networks on: January 25, 2018, 07:02:16 AM
I've been reading up on Signature aggregation and usage of lightning networks on certain blogs recently. I've had a couple of questions on the top of my head which I couldn't find answers to on subsequent searches. Also, since I have multiple questions I feel I should ask them in one particular post. I would be glad if anyone knowledgable on the topics could help answer few of my questions. My Questions are:

1) Will signature aggregation / Key aggregation be available for legacy addresses that start with '1' or are these only for multi-signature addresses that start with 3 or bc1? If not, could somebody explain to be in an easy to understand way on why is this the case?

2) I've tried opening a lightning channel using the lightning-app on testnet, I really loved playing around with it and am Impressed with the instant payments. I was wondering if anyone else could send me ligthning payments (me receiving them) if my channels were already fully funded and the 'Available to receive' is '0'. If this were to be the case, would the sending party have to independently open a new channel with me to send me the funds instead of having to rely on existing channels?

3) Will the users be allowed to set an nLockTime or a time period after which the channels will be automatically broadcasted to the bitcoin network and closed? Currently I've tested Eclair for android, lightning-app and Bitcoin + lightning wallet for android and they all seem to not provide this option. I'm assuming it's a 'To be developed' thing?

4) Will I need a lightning node with a public IP broadcasted in order to be able to earn from fees for nodes using my channel to transact between each other?
4  Bitcoin / Bitcoin Discussion / What helps keep the fee on the Lightning network low? on: January 15, 2018, 06:19:03 PM
The lightning network is a great technology and I've been deeply interested in how it works upto the extent that I've previously setup lnd and lightning-app to try out testnet payments on bitrefill and other similar lightning testnet payment gateways. I've had a question on the top of my head which I can't seem to figure out. I believe we all need to open and connect either directly to individual lightning channels or to a channel that's connected to many other nodes. This large channel that we connect to needs to have sufficient funds such that if I'm to pay a huge sum to a 3rd party through that channel very often then the channel should be well funded. Consider there's risk of that channel to keep huge sums of funds and many connecting to that channel to perform transactions, wouldn't it eventually make node operators charge a higher fee as more and more transactions happen at peak intervals? Also, if I would want to run my own node that is connected to many other nodes would I require huge amounts of funds to be open in that channel to earn fees or would it be good to start small and then risk more later?
5  Alternate cryptocurrencies / Altcoin Discussion / Is there an Android / iOS wallet for Decred? on: December 31, 2017, 06:05:29 PM
Hi,

I'm in search for a Decred mobile wallet (preferrably OpenSource) as I'd want to be able to access my funds on my phone. I believe Decred has a webwallet (the copay source fork) and it seems to work fine, but I'm looking for one which will also provide me the ability to buy tickets (using Proof of Stake mining) and stuff like those on my mobile device. Are any of you aware of one at the moment or are using one?

Thanks
6  Bitcoin / Wallet software / Connecting to Tor full nodes on Bread Wallet on: December 25, 2017, 04:36:30 PM
Hi,

I have a small problem being able to establish a manual connection to bread wallet to my TOR full Bitcoin node. Currently, I'm able to locally synchronize the block headers by connecting to my local internal IP (For example on my computer running TOR full node on IP - 192.168.1.1:8333), I am able to connect to this local IP to my bread wallet when I'm on the same internal network for my phone.

The only problem is breadwallet doesn't support inputting tor addresses because the input field only supports numbers (IPV4 addresses). There's the possiblity that people could be running IPV6 and Tor full nodes as well which now users can't connect to. I noticed that I could copy paste my TOR address into the numeric input field in Bread Wallet, but on clicking OK it isn't validating it or connecting. For your info i'm using iOS (jailbroken) with TOR running and my other apps can connect through TOR (Same case for my android phone).

Has anyone else managed to connect to a TOR full node on their beadwallet app for android or iOS?


Thanks for taking your time to help out.
7  Bitcoin / Development & Technical Discussion / Questions on 'New Opcodes' to be implemented in elements on: November 16, 2017, 06:23:07 PM
Hi all,

I've been reading through the various element's projects that become a part of the sidechain. I've read through New Opcodes and I was confused about how the two use cases - double-spent protection bonds and probabilistic payments worked.

Doesn't Bitcoin already have considerable protection against double-spends and how are these protection bonds associated to it? Also I wasn't able to determine what probabilitic payments were, At the moment the source code page takes me to a 404 page (https://elementsproject.org/elements/opcodes/elements/opcodes/index.md) which I'm hoping might be resolved soon.

I hope someone which some knowledge on this would be willing to throw some light and help me understand?
8  Bitcoin / Development & Technical Discussion / MOVED: Why do full nodes over TOR have a less ASN index score and clients connected? on: August 07, 2017, 04:54:39 PM
This topic has been moved to Technical Support.

https://bitcointalk.org/index.php?topic=2069469.0

Sorry, posted it in the development section by mistake, figured it's suitable to be in the Technical Support section.
9  Bitcoin / Bitcoin Technical Support / Why do full nodes over TOR have a less ASN index score and clients connected? on: August 06, 2017, 02:48:46 PM
Hi All,

I've been running a Bitcoin Core full node over TOR and was browsing through the leader board https://bitnodes.21.co/nodes/leaderboard/

I've noticed that majority of the TOR nodes have a low ranking and a low ASN Index score (somewhere around 0.37 to 0.388).

According to Bitnodes the formula for deriving ASN Index score is:

Code:
AI = ASN index
 AI = ln((1 / n) x N) / ln(N)
    N = number of reachable nodes
    n = number of nodes from N with the same ASN  

I've also noticed that a max of running my TOR node for 1 week continuously, I've had a total of 12-13 connections with about 8 outgoing and 3-5 Incoming. Hence my bandwidth consumption has been pretty low running a full node over TOR. The max bandwidth used is about 1.6 GB (sent / received summed up).

Hence, I was wondering does this make Full nodes over TOR in anyways less reliable for the network? I've noticed when I was able to run a full node without TOR (a couple of months back before I switched my ISP. My current ISP doesn't allow forwarding ports, hence I'm running over TOR to get incoming connections) a lot of clients would connect (At about 40-50 connections). I'm running this node on a high-end CPU (8 cores, 16 threads), 16 GB RAM and a decent internet connection speed (about 10 MBPS up and down).

Kindly share your thoughts on what could be the possible reason for low ASN index scores / node connectivity over TOR?

Thanks for helping.
10  Bitcoin / Bitcoin Discussion / Bitmain's new Xinjiang computing center to be completed this December. 140,000kw on: November 02, 2016, 05:15:19 PM
I noticed a user 'TheBlueMatt' posted this on reddit - https://twitter.com/cnledger/status/793675026402717698

The Bitmain's possible new mining farm would be completed this december and would easily own a lot of mining power and hashrate. Does this seem exciting or concerns you over centralized mining power in China?

I feel this is good investment for the Chinese and I'm sure they're earning a lot from mining Bitcoins. I'm just hoping that all of this is for the benefit of the Bitcoin network as well.
11  Bitcoin / Bitcoin Discussion / Is running a node getting costlier? on: September 22, 2016, 04:49:53 PM
Hi All,

I used to run 2 Bitcoin nodes, one on my PC and on Microsoft Azure platform (I had a free 3 year Azure subscription for upto a certain amount of dollars worth of credit). I feel the blockchain size is constantly increasing by a lot and that connection speeds aren't great in a place where I live. I do have 4G networks but they aren't as cheap to buy. On Microsoft Azure I have ran out of disk space as well. I found running a node a good go as a hobby, but it's probably nice for larger companies and places where hard drive and internet is cheaper to run.

What's your take on it?
12  Local / India / For you book lovers - Sapna books online accepts Bitcoin via Unocoin on: September 18, 2016, 06:54:31 PM
Hey,

I just noticed that sapnaonline's bookstore accepts Bitcoin payments during the final payment checkout page. The payment system is powered by unocoins payment gateway. This is really exciting and has made it easier for the younger population in India to pay using Bitcoins.

Let me know if anyone found this useful.
13  Bitcoin / Bitcoin Discussion / Can the ones that hacked Bitfinex bitcoins sell them after mixing the coins? on: August 06, 2016, 12:14:14 PM
Hi,

Just wanted to know since most exchanges practically would be aware of this news and would keep track of the movement of these coins. Is it possible for those who hacked the Bitfinex Bitcoins, be able to mix/tumble them either with other cryptocurrencies or online mixing services and then short them?

Do you think it's truly untraceable then?

What could be the possible disagreements? Can't wait for him to explain them on LTB Cheesy
15  Economy / Service Discussion / Is there a brawker.com like service available? on: November 14, 2015, 01:47:51 PM
Hey,

I used to purchase a couple of goods on Brawker.com using Bitcoins (this wasn't limited to amazon.com or ebay, but on any e-commerce site). Basically they had a tagline for their business called "Purchase anything anywhere with Bitcoins". The concept was to have a middle man who basically wanted Bitcoins who in exchange would purchase any goods for you on an e-commerce website or make payments/pay the charity amount on gofundme etc and in return you would pay him/her Bitcoins. They even had an escrow for every transaction that happened.

I was wondering if there were any more decentralized services like brawker where basically you could do the follwing:

As a middle man - Purchase/receive Bitcoins by buying goods for others on various websites using your credit/debit card or cash.
The Purchaser - Has bitcoins and is wanting to buy something on some merchant not supporting Bitcoin payments.


Was wondering if anyone could suggest me few legit ones, without having to worry about fraudulence.

16  Local / India / Buying Bitcoins in India using debit cards or netbanking? on: November 08, 2015, 01:18:36 PM
Hey,

I was wondering if there were any exchanges availing the facility to purchase Bitcoins using debit cards or net banking within India. Considering the ease of making payments using debit cards or net banking without going through the hassle of paying additionally or the delay of waiting using NEFT or IMPS, a service to buy bitcoins quickly using debit cards would be beneficial.

Would be glad if anyone was aware of the existence of such an exchange and was willing to share it.
17  Bitcoin / Electrum / Custom electrum plugins not showing up in electrum plugins menu? on: March 04, 2015, 09:44:33 AM
Hello all,

I followed the electrum plugin creation tutorial from talkera, but when I paste the code of reddit.py in the electrum plugins folder and restart electrum, it doesn't show up under the plugins menu box. I have electrum 2.0 on a windows system installed.

Thomas suggested on IRC that the code might be depricated, but I couldn't find out which part on comparing with other already available plugins.

This is the code:
Code:
from PyQt4.QtGui import *
from PyQt4.QtWebKit import *
from PyQt4 import QtGui, QtCore
from electrum.plugins import BasePlugin, hook
from electrum.i18n import _

class Plugin(BasePlugin):


    def fullname(self):
        return 'Reddit'

    def description(self):
        return '%s\n%s' % (_("Reddit dialog."), _("From the nice developers at talkera.org "))

    @hook
    def init_qt(self, gui):
        self.gui = gui
        self.vkb = None
        self.vkb_index = 0
        self.gui.main_window.tabs.addTab(self.create_tmp_tab(), _('Reddit /r/bitcoin') )


    def create_tmp_tab(self):
        w = QWidget()

        grid = QGridLayout()
        grid.setSpacing(8)
        grid.setColumnMinimumWidth(3,300)
        grid.setColumnStretch(5,1)

        self.web = QWebView()
        self.web.load(QtCore.QUrl('http://reddit.com/r/bitcoin'))
        grid.addWidget(self.web, 2, 0, 1, 6)
        w.setLayout(grid)

        w2 = QWidget()
        vbox = QVBoxLayout()
        vbox.addWidget(w)
        vbox.addStretch(1)
        w2.setLayout(vbox)

        return w2

I also tried this plugin and copied its contents into the plugins folder https://github.com/bkkcoins/papergen and it wont show up either. Can someone kindly help me?
18  Bitcoin / Electrum / Does the new Electrum 2.0 Beta convert our old seed wallet from 1.9.8? on: February 02, 2015, 04:21:59 AM
Hello all,

It's nice to know that Electrum 2.0 beta is out.

I have a couple of doubts with regards to the new version of Electrum.

Question 1: I remember Electrum 1.9.8 had a 12 word seed, but Electrum 2.0 has a 13 word seed on a standard wallet. I opened up my Electrum 2.0 beta and I've seen the seed showing up as 12 word seed, but when I create a new Electrum 2.0 standard wallet it gives me a 13 word seed back for the wallet. May I know if Electrum 2.0 will convert my old 12 word seed or HD wallet to the new 13 word seed or new standard?

Quesiton 2: Whats the difference in wallet architecture from 1.9.8 and 2.0 beta? I heard 2.0 beta has BIP 32, didn't 1.9.8 have BIP 32 or HD wallet?

Question 3: Will there be the ability to easy convert old wallet from 1.9.8 to new wallet of 2.0, or also to Multi sig wallet or 2FA wallet?

Kindly guide me on this.

Thank you
