Would it be possible to set up a Bitcoin Core pruned node and attach it to one of the existing lightning network node implementations, or does one need a full (archival) node?
Also, what lightning node implementation is compatible with the Bitcoin Core software?

I guess the Semux btc airdrop requires the distributors to check if the btc account had a balance at a given time, right? In the form people only provide the semux address and the signed address. How do you check if from the signature what btc address somebody used to sign? Can you reverse engineer it?

Despite the geeky nature of the subject, Blockchain technology, cryptocurrencies, and ICOs (Initial Coin Offering) are receiving a lot of attention, and will soon demand more of yours. This is largely thanks to the meteoric rise of Bitcoin’s value in the last few years, and its promise to bring about a fairer economic world.
The 9 year-old crypto currency is trading at around $4900 at the time of writing, up 680% from same time last year. Analysts are suggesting Bitcoin will change how we will do business, legislation, and everything else that currently requires a central authority. It's even likely it will change the way we approach advertising too. Please read the full article and let me know if I got something wrong, or if you have suggestions on how to improve it: http://clios.com/the-muse/how-blockchain-will-change-advertisingThanks! |

Hey guys! Sorry for the late update. I've been swamped with work and writing a review here just kept getting pushed to the bottom of the list. I wanted to do a really solid, play-by-play review, but I've just got too much higher-priority stuff going on. TL;DR: I'm happy with the service I received. After filling out the form and sending the bitcoin requested, I received an automated email confirming my order. There was silence for a while after that, so I emailed Ivan around three days later and received an apology shortly after stating that he'd been having issues with his email and hadn't received the order notification. Four days after that, I received an email (which went straight to my spam folder, so it's good thing I'd been checking there) with eight proposed logo designs. After a few days of consideration I chose the one I liked best. Two days later I received an email with two zip files and a PDF. The PDF was a single-page "corporate identity" guideline, with hex codes for the colors used in the logo and the name of the font, as well as various renderings of the logo: buttons, an app icon, a vertically-oriented logo, a horizontally-oriented logo, and a "general use" logo. One of the zip files contained various 3D renderings of the logo: the app icon rendered in brushed metal, the "general use" logo rendered in brushed-metal-on-leather, the "general use" logo rendered in embossed-foil-on-paper, and the vertical logo on a piece of paper with a suggested mission statement underneath, hung from string and paper clamps in front of a white wall. The other zip file contained the logos and the app icon from the corporate identity PDF as PNGs, plus a white-on-transparent rendering of the "general use" logo. All the PNGs in that zip file were 1000 pixels on their longest side. You can see the logo I chose up on my placeholder website at http://liftofflabs.co/Thanks for the review! |

Yes, it's 900 mBTC or 900K bits.
I can do a logo at any price range, but I don't think it's worth to have a logo that somebody spent only 30 minutes on in total, which is what you get for 0.1 BTC. It's a logo that is usually uninspired and even a copy of something that exists out there. Doesn't enhance the brand and doesn't contribute to the success of the company. It's not something the owner wants to etch into the marble floor of his office. It's just a mark that is temporary and will be changed as soon as the owner realizes the value of a good brand. A 0.1BTC logo is a different type of service from what I offer.
I do realize that you can be lucky in 5% of the cases and you may get a good logo for a few mBTC by chance or because you find a designer who does proper work for the fun of it. But in the large majority of the cases the client will only waste his time and money on such exercises.
I think one such example was the Nike logo where the student designer created a symbol that made the company famous and it cost only like .2BTC in Today's money. But that stands against thousands of great logos that cost in the range of 1BTC-100BTC.
For a good logo you need to spend time on understanding and clarifying the client's needs, which is at least 30-60 minutes unless you work with a very experienced client who gives you a great brief from the start.
You need to do your research into the industry, this can be again at least 30-60 minutes. If you're lucky you may be working on an industry you know very well, so it can be less.
You need to do brainstorming or ideation for at least 2-3 sessions 30 minutes each.
You work out 3-4 concepts for the client for at least another hour or more.
If you're lucky the client likes one option and you spend at least an hour perfecting it and then developing various color and layout options to develop a small identity guideline for another hour or so at least.
If you add it all up it's at least 5-6 hours till completion if everything goes smooth. That means ~$50 / hour fee, which is very fair and even a bit too low for a seasoned professional.
Also, 0.9BTC for the face of your company is nothing. You can make that up with the first deal you make with your client. A good logo can raise the valuation of your company and sales instantly by 5-10%. That's why companies spend literally hundreds of thousands of dollars on rebranding efforts. It's a good investment.

PayBase's logo is way too similar Gopago's  Here is my suggestion:  What do you think? |

what?
I guess time will tell... we KNOW the number of txs are going to multiply- what's your prediction? smooth sailing? are you an active backer of this technology project?

No, I'm not in any way related to Coinprism. I certainly don't want to harm bitcoin, but the whole thing is an experiment and it should be tested in this way too. We can rely on people not doing projects like Coinprism in order to keep Bitcoin running smooth. It has to defend itself if it's a potential problem. I don't have a prediction. I don't have enough knowledge. I guess it will work fine. |

no your thinking is off. Color Coins and Counterparty create an INCENTIVE to create many many more transactions that don't have a strict BTC value.
all these discussions already took place on the BitcoinX list.

You mean killing Bitcoin just for the sake of it or to piss off bitcoiners for the price of a few dollars wasn't enough incentive? |

Color Coins is going to overload the block chain and cause major problems with the core bitcoin features.
-bm
Interesting question. If Colored Coins could choke Bitcoin it means the anybody can do such an attack regardless of Colored Coins. I think that's why we have the 540 Satoshi dust limit. My understanding is that currently there is a 7 transaction per second limit on Bitcoin, that means if you send 5,000+ transactions in 10 minutes it would go beyond the limit. You can do 5,000 transactions for just 0.027 BTC. |

the obligatory 0.0001 transaction fee is a bit of a pita for playing around with these colored coins,
which are only 0.000006 each
It's not compulsory by Coinprism. You can send with none, but I don't know how fast it will be sent if at all. We can try sending it with 0.00001 BTC (1/10th of the suggested fee). |

OK, I created my own colored coins called "Worthless Tokens" with ticker symbol WTK.  But I can't figure out how to send them to someone (for example to bish5555's Coinprism wallet that he posted above). Any ideas? Haha, I will destroy the idea of WTK by offering 0.001 BTC per WTK!  |

Sure, I'll bite. I created a CoinPrism wallet and was assigned the address: 1DAXAwYFencj3CXWhcjUg6Fvo3JhjRxrev So are OwlCoins redeemable for anything real or are they just for experimentation? I am still interested in the answers to these two questions: 1. Does the open-assets protocol have a formal and publicly-visible method for an issuer to remove the color from a coin? 2. Can colored coins using the open-assets protocol be traded via coinjoin transactions? Sent it. 1. I think so, when you send it to a new address without the meta tag it becomes uncolored (recycled). I think that's what Coinprism does when it uncolors. 2. Sorry, I don't know. |

 If anybody wants I can send 1,000 Owl Coins as a test. It's a Colored Coin that runs on Bitcoin network and the Open Assets protocol. You will effectively receive 600 Satoshis carrying the Colored Coin meta data. In order to be able to receive the Colored Coins correctly you need to have a bitcoin address / wallet that understands the Open Assets protocol. In practice this means you need to create an account at Coinprism.com and then give me the address it created for you. |

I am not sure how much bitcoin you actually need to make it work, but I assume it is larger than the dust limit but still quite small. I would like more clarification here too.
Yes, the dust limit in Bitcoin is now lowered to 540 Satoshi (at Bitcoin v 0.9) from 5,400. In Coinprism it was rounded up to 600 Satoshis. This the amount used to send the transaction and carry your Colored Coins. It doesn't matter if you send 1 or 10,000 colored coins, you are still technically sending 600 Satoshis to the recipient. |

Ok so when i color some bitcoin, the amount of bitcoin colored is not relevant, right ?
To go back to the applecoin :
If i create 100 applecoin for my apple growing company, can i just color 100 satoshi to trade?
What is the difference if i color 100 bitcoin?
Am i missing something?
You're right, it's not relevant because the amount is so small. But if you had for example 1,000 colored coins incoming transactions than you can uncolor them and recycle them back to bitcoins. Each transaction is 600 satoshis, so you would have 1000x600 Satoshis or 0.006 BTC ($2,64). |
