Also check out bcoin http://bcoin.io/  Started as spv project but is now a full node implementation in javascript.  Made in part by purse.io CTO    See Let's Talk Bitcoin episode #319 for good interview on how the project came about

Gleb, when I see you posting this types of things I wonder how your storing this data.  I imagine you having a room with post its and strings.  If you haven't looked into Neo4j, check it out, it's a free graph database.  You can create nodes (nosql records of any data) and connect them with as many arbitrary relationships as you want.   The relationships themselves can have properties example:

[Josh] ----- Fucked a ----> [Rabbit] ---  eats --> [Grass] <--- sprayed with --- [Monsanto Herbicide]

You can then visualize these nodes and relationships and ask things like "Is Josh connected to Monsanto ?" and see the path.  It's good at answering the how am I connected to Kevin Bacon question.  I haven't used it for a long time but it was easy to setup and has a web interface to visualize and add data.  May be able to find connections not obvious when the data sets get large.

More security.  If you had to sign transaction from key on your computer, then sign it from key on your phone attacker would need to compromise both devices.  Something like 2 factor authentication

Re: Are Satoshi's percentage of BTC a serious problem for government acceptance?
by
oldbute
on 27/01/2016, 16:44:50 UTC
If I understand you're saying other governments are afraid some government created this? Not sure if you're saying US or specific country.   It's an interesting thought but my problem with it is it's too complicated.  Too many people would have to be involved, how was it funded? was the central bank of that country involved? 

A much simpler explanation is that some cypher punk or 2 or 3 put together ideas and technology in a way nobody thought of.

Now if you were to say a government captured Satoshi at some point after he released it and is now holding him and/or his private keys, seems more plausible.  Guess the question is if other governments think these theories are true why not say it?

Re: Best way to explain to someone how private key is not exposed...
by
oldbute
on 14/01/2016, 04:51:17 UTC
I think you're on the right track, don't use analogies, explain how it really works in steps. 

There exists a mathematical relationship between a 2 numbers, a private key and a public key where you can prove you have the private key without showing it.  This proof is called a signature.   If they believe that is a real thing Smiley go further down the rabbit hole.   The fact that you cannot determine the private key from a public key and the fact that these are massively large numbers are important.   Not sure you need more than that, could go into some details on how transactions are relayed and verified, leave it up to them.

The details are complex but the concepts have to be agreed on for the most part, not understood in detail.  Let's agree my car moves when I push the gas. Ok, now you can dig as far as you want into the details of how that happens, but for our lesson today let's move on to the fact that the wheels turn when I rotate this wheel.

Re: Multisig address question
by
oldbute
on 13/01/2016, 03:11:23 UTC
Thanks for the advice.

This address is no longer usable as I have lost the redeem script. Someone sent some 300 bits to the address but I think it is lost forever... It has effectively became another bitcoin burning address... sigh..

I will try again to generate another throwaway address and will play with it, before I actually generating a real address.

If you have the public keys should be able to re-create the redeem script / address the same every time.   See this example from bitcoinlib js

https://github.com/bitcoinjs/bitcoinjs-lib/blob/master/test/integration/multisig.js#L8

Redeem script is

Put the pubkeys in the same order and should get the same result

Re: Bitcoin as a way to avoid corruption

I had a thought along these lines.  The idea is make it an option to make your tax payments directly to gov depts or organizations you want.  A % of the budget is controlled directly by persons paying taxes and not though your representation.  Bitcoin makes verifying these types of payments possible where checks/credit cards would add too many administration costs.

Re: How could I run a full node on Ubuntu?.

on 31/12/2015, 00:28:57 UTC
You may want to open or forward port 8333 to get more connections to your node.  https://bitcoin.org/en/full-node#network-configuration

Only 8 connections are allowed outbound, you can see number of connections from bitcoin-cli getinfo.  To see who is connected can use bitcoin-cli getpeerinfo

See here for all the RPC commands https://bitcoin.org/en/developer-reference#bitcoin-core-apis You can get information about connected peers, see mining information, all you can handle bro

Re: Best T-Shirt "I AM" or "I AM NOT" Satoshi
by

on 30/12/2015, 16:11:28 UTC

Maybe I can help. I studied translation for several years ( Grin): '"I am not satoshi" sounds great but it would be even better if completed with a second sentence saying "... but I am a bitcoiner" (likely on the back of the shirt, I guess)'.


I think saying I am a bitcoiner is redundant, the shirt is for bitcoiners.  I have seen this shirt in a few places.  It's a very old idea, not mine. https://bitcointalk.org/index.php?topic=13941.0  Some good suggestions here I will check them out , thanks.

Re: Capacity increases for the Bitcoin system

What do you think is safe? We must keep a safety margin, don't we? On my hard disks, I always keep at least 15% of free space. In my car, whose engine can rev to 6,500 RPM, I rarely exceed 4,500.

Good chance they already engineered that 15% into the 6,500 red line.  My 1978 Yamaha motorbike red lines at 9,000 I try to get there all the time.  Come on let those horses run!

Re: Why even use BitCoins? (read the post!)

on 21/12/2015, 04:32:21 UTC
If you're strictly comparing using btc vs debit cards for shopping on the Internet, I agree it's not a huge breakthrough or game changer.  I think it is a way more secure but we have a system where you're not responsible for unauthorized charges on your accounts...  Imagine if you were responsible for unauthorized charges on your credit cards, nobody in their right mind would ever use a debit or credit card because the storage of those #'s is not in your control.

Also your assumption that you have to give up privacy for shipping is not correct though https://www.privatebox.co.nz

So are you concluding it's a useless idea because it doesn't make shopping easier for you?

Re: Bitcoin user adoption is horrible - here is why:
by
oldbute
on 18/12/2015, 15:10:15 UTC
In buying a coffee with BTC my main concern will be to have to pay at least 5 cents for a transaction fee.
By paying with card the merchant pays the fee while paying with BTC we pay the fees. I think that's the main adoption problem in buying a coffee with my bitcoin

I think you'll find merchants would give you discount to pay in bitcoin.  Lot of gas stations give cash discounts, the credit card fees are built into the prices, don't think your not paying them.

I would rather give .5 to a miner, give more money to the merchant and keep 3% away from the bank regardless.
