1  Economy / Digital goods / [Domain]Bitcointalk.COM on: May 12, 2018, 02:26:52 AM
Anyone interested in buying Bitcointalk.COM?  I use for domain transactions.  these domains are also available: - US Trademark for providing a Bitcoin blog
2  Economy / Digital goods / domain - free* on: December 09, 2015, 06:51:52 AM
It is expired but can still be transferred/renewed.  *You must pay for a domain transfer/renewal from the registrar of choice.  Godaddy has a sale for $9.99 but renewals down the road will be about twice that.

Let me know if you want it and I will send the auth code needed to transfer.

3  Bitcoin / Project Development / Product reviewers on: November 02, 2015, 01:58:15 AM is a brand new site and has no articles, traffic or income yet. I would like to see if it is feasible to have a much wider range of authors than what you see at most news sites. As a first step I would like to focus on product reviews.

Looking for people to write product/service reviews. The reviews should be balanced and should not be just a news release or some complaint. If you are interested in writing a review leave a message at (I don't generally read messages sent through here)
4  Bitcoin / Bitcoin Discussion / Priceton U. Bitcoin Class - Free! on: February 17, 2015, 08:45:57 AM
The Princeton University Bitcoin class has started.

This is an online version/offshoot of the class they taught last semester:

I am enrolled and I went through chapter 1 and lecture 1:

I would highly recommend this class based on what I have seen so far.  Even if you don't understand the fine points of the math or can't do the programming assignments I would try to take the class anyway. 

Education is the most important thing in the Bitcoin space right now.  the space is being overtaken by groups of cultists and nut jobs both for and against Bitcoin.  On one side you have Roger Ver, Erik Voorhees, Stephanie Murphy, Cody Wilson, Theymos, Charlie Shrem, etc. and on the other side you have Neil Palmquist, Buttcoiners, etc.  Those Al Sharpon wannabee agenda-pushers are completely distorting things.  It is like listening to Rush Limbaugh and Al Gore debate global warming.  You may notice when something like the Princeton class shows up these people are nowhere to be found. 

As Bitcoin progresses knowledge will be pushing the "wing nuts" back into the woodwork so don't be left behind.  Things like this class and people like Jerry Brito at Coin Center are what is going to drive mass adoption, not the foaming-at-the-mouth cultists who promote an agenda that has zero chance of acceptance by most people.

Send a customized letter from Santa sent on holiday stationary for 10 mBTC.


See or

The letters are being printed now and will be sent out in the morning.  Send a message to anyone ... you can include a Bitcoin promotional coin and/or car decal from if you want to make it a Bitcoin message.
6  Bitcoin / Legal / Bitcoin US trademark opposition on: December 09, 2014, 03:08:38 AM
I filed a 30-day extension today.  I drafted an opposition and I have until early January to file it.

Since Bitcoin is not owned by anyone there is generally nobody to oppose these things.  The Foundation said they were looking into it about 18 months ago but I have never heard anything.  Advice from someone who knows about TTAB filings would be good.  If someone want to file an opposition there is 3 days left to get an extension.
7  Bitcoin / Legal / Bitcoin nut job sues NY State for $1 Billion on: October 27, 2014, 05:36:26 PM
Some nut job is on reddit looking for legal advice for the lawsuit he filed:

He is focusing on the fact the answer from the State of NY points out that he sued the wrong party.  He doesn't mention the main reason for the request for dismissal is that he failed to show any link between proposing rules and him losing $1 Billion.  He also send rambling letters to the Court how Lawsky is screwing up the proposed regs and he even mention p2p technology and issues with gold as a commodity.  He says he will drop the case if the State drops the BitLicense proposal ... as if the court clerk is going to go over to Ben Lawsky and end the proposed license.

"Official site offering documentation, forums and the open source client software which permits to send and receive bitcoins."  - Site Description showing up on Google.

" is not an official website. Just like nobody owns the email technology, nobody owns the Bitcoin network. As such, nobody can speak with authority in the name of Bitcoin."

Most users will see the description that appears in Google and will never read the disclaimer on the other page.

11  Bitcoin / Armory / Old unconfirmed Dust tx's won't go away on: October 05, 2014, 12:59:09 AM
I have a couple of those unconfirmed tx's from those 1Sochi 1Laxo addresses and they are more than a month old.  Gavin posted this about the QT wallet

That is a feature of Bitcoin-Qt. Unconfirmed dust transactions don't enter the memory pool, so they are not relayed, not included in blocks being mined, and not displayed by the wallet.

If I recall correctly, if they DO get mined into a block by somebody then they are displayed. Ignoring them and not adding them to the wallet in that case might be a nice feature, although today's dust might be tomorrow's treasure if prices rise another couple orders of magnitude.

Why do these tx's show up on the Armory wallet at all and why are they there more than a month later?  Normally they disappear after a couple days.  Does it mean they are being rebroadcast or is it some other reason?

13  Economy / Digital goods / domain name on: September 23, 2014, 11:53:32 AM domain name.  This domain expires soon so make an offer for a quick sale.

must be transferred out to a registrar you choose at your expense, cannot be pushed.
14  Bitcoin / Bitcoin Discussion / and Jerry Brito on: September 18, 2014, 09:26:02 PM
I just saw the announcement.  Jerry Brito is one of the best advocates for Bitcoin in Washington, DC.  I hope this organization is separate from the Foundation.

Many people on here will discuss all kinds of conspiracy theories about the Bitlicense and other regulatory issues.  The fact is one of the main reasons is complaints from within Bitcoin users themselves.   Huge numbers of complaints have been generated by Bitcoin businesses and things like Bitinstant, Satoshi Dice Investments, pirateat40, Mt. Gox, Bitfloor, BFL, etc. have all generated complaints to regulators.  The regulators don't know what to do so they propose all kinds of screwed up regulation.  Since this stuff is going to happen anyway Jerry Brito is probably the best person to deal with it.

Listen to Jerry Brito

15  Economy / Digital goods / domain - xbt exchange on: September 18, 2014, 03:27:52 PM domain name.  15 mBTC

Good for a site to provide Bitcoin exchange information.

this domain must be transferred into a registrar you choose at your expense.  You can use places like namecheap to use Bitcoin ... or Godaddy and find a coupon code
16  Bitcoin / Development & Technical Discussion / Re: ECDSA Signatures allow recovery of the public key on: September 14, 2014, 04:51:27 PM
The original reference was taken down awhile back.  I got a copy off the Wayback machine and put it at

This is how you get the public keys from the signature:

4.1.6 Public Key Recovery Operation
Given an ECDSA signature (r, s) and EC domain parameters, it is generally possible to determine
the public key Q, at least to within a small number of choices.
This is useful for generating self-signed signatures.
This is also useful in bandwidth constrained environments, when transmission of public keys cannot
be afforded. Entity U could send a signature to entity V , who recovers QU. Entity V can look
up the public key in some certificate or directory, and if it matches then the signature can be
accepted. Alternatively, entity U may transmit the signature together with the certificate except
that the public key is omitted from the certificate. For example, in long certificate chains signed
with ECDSA, bandwidth can be saved by omission of the public keys.
Potentially, several candidate public keys can be recovered from a signature. At a small cost, the
signer can generate the ECDSA signature in such a way that only one of the candidate public keys
is viable, and such that the verifier has a very small additional cost of determining which is the
correct public key.
Input: The public key recovery operations takes as input:
1. Elliptic curve domain parameters T = (p, a, b, G, n, h) or T = (m, f(x), a, b,G, n, h) at the
desired security level.
2. A message M.
3. An ECDSA signature value (r, s) that is valid on message M for some public key to be
Output: An elliptic curve public key Q for which (r, s) is a valid signature on message M.
Actions: Find public key Q as follows.
1. For j from 0 to h do the following.
1.1. Let x = r + jn.
1.2. Convert the integer x to an octet string X of length mlen using the conversion routine
specified in Section 2.3.7, where mlen = d(log2 p)/8e or mlen = dm/8e.
1.3. Convert the octet string 0216kX to an elliptic curve point R using the conversion routine
specified in Section 2.3.4. If this conversion routine outputs “invalid”, then do another
iteration of Step 1.
1.4. If nR 6= O, then do another iteration of Step 1.
1.5. Compute e from M using Steps 2 and 3 of ECDSA signature verification.
1.6. For k from 1 to 2 do the following.
1.6.1. Compute a candidate public key as:
Q = r−1(sR − eG).
1.6.2. Verify that Q is the authentic public key. (For example, verify the signature of a
certification authority in a certificate which has been truncated by the omission of
Q from the certificate.) If Q is authenticated, stop and output Q.
1.6.3. Change R to −R.
2. Output “invalid”.
17  Bitcoin / Bitcoin Discussion / Wallet list at on: September 11, 2014, 08:50:54 PM
I see the disputes are starting to arise over the content at  the latest is the includion of the Pheeva wallet (see

Gavin of the Bitcoin Foundation posted this unhelpful reply "The Foundation sponsors, but has no control over the content-- the content is community-created and controlled."  of course this is meaningless statement that does not clarify who exactly has control over the content at  I know anyone can submit a request at Github but that does not explain who makes the final decisions about what gets published.  Gavin's statement is meant to divert attention from telling everyone who actually makes the decisions concerning what is published.  This constant lack of transparency has caused many people to leave the Bitcoin Foundation.

It is about time the people involved tell everybody who decided which wallets get listed, which conventions get promoted, which people are put on the press list and why, and on and on.  Nonsense replies that claim some "community" did it are not helping.

I completed the certification process at Took the 20 minute/75 question multiple choice test, paid $50 CAD test plus $25 CAD certificate application fee (BTC only) and uploaded a resume. Got my CBP certification in a few hours.
19  Economy / Digital goods / BITCOINS.NET Domain Name on: August 18, 2014, 05:04:55 PM
BITCOINS.NET domain name. 

I have been getting several inquiries about this domain and I would figure I would post here to gauge the interest. Send an email if you want inquire.  thanks
20  Bitcoin / Project Development / Atlantic City Bitcoin Projects on: August 04, 2014, 02:50:57 PM
Atlantic City Bitcoin will be launching a number of projects over the next few months and partnerships are being considered.  Any type of partnership could be considered.  Several top web sites have been acquired and the only way they can be developed is to seek partners.  

Atlantic City Bitcoin previously obtained the ruling from FinCEN which was very favorable to US miners: - The web site was acquired several months back from some bitcoiners.  A professionally made sequel to the WeUseCoins is just finishing up.  This took about 9 months and a voice-over artist that, ironically, does HSBC commercials in Europe is doing the video.  The video focuses on showing practical situations where Bitcoin can be used more efficiently than current systems.  The site will provide background material more in-depth than what you find now at many other introductory sites.  The video was made by the Brolik agency.  Support issues will be moved to - This site was acquired from the portfolio of Frank Schilling ( and is clearly the best domain for a news site.  One idea is to do something similar to which is a scheme where you have a primary editor and stories from various sources are chosen to be reprinted.  However, nothing is set in stone and ideas will be considered. - Directory of places to buy food with Bitcoin.  Listings are free.,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ...  These web sites are currently undeveloped and looking for partners.

There is not much time to post discussions here so the best thing to do is to contact me directly with ideas/suggestions.
