My Open Letter to Bitcoin businesses: Why I'm closing my accounts

(The following letter was sent today by me to a number of bitcoin businesses. I posted my Bitcoin Foundation forum post to Reddit to check on the reaction, and it seems to have gone straight to the top.  I'll be increasing my advocacy for anonymity as well as learning much more about code than I presently do, so that I can do better in the future at helping build the solutions I'm advocating for.  As an aside, if you've read my blog before, you'll note that I used to have a Coinbase button which you could click on to donate bitcoin to me ~ that's been removed.  Additionally, I've removed the script in this blog that prompted people to donate with BitPay.  This is simply a part of my dis-intermediation process, as my accounts with Coinbase and BitPay (and other similar web-based services) will soon be closed.)

Dear innovators in the bitcoinisphere,
I hope you'll take a moment to read my recent post at the Bitcoin Foundation forum, titled "Open Letter to Bitcoin Businesses:  Why I'm closing my accounts."

You can also see some of the comments from some leaders in the Bitcoin business field regarding my letter here on reddit.
Some of you may observe that I'm sending you this message from a gmail account.  I hope that the same principles that I'm advocating for in the bitcoin business community, will also be adopted by providers of e-mail and other primarily web-based services. 
So, I've copied Google and PayPal (and some others) on this email as well.

My exit strategy post-account closure will primarily involve use of fully decentralized exchanges or brokerages such as OpenBazaar and BitXBay, wallets where the software and the keys reside on the users' computers such as Electrum or Armory, use of alternative currency systems that preserve or enhance anonymity such as BCN and Zerocash, and as well, my ongoing advocacy favoring anonymity as an option that I hope more companies will come to adopt.

Bitcoin Privacy Developments, Power Ecology, and Helping the Homeless

Today's blog will briefly cover some recent privacy developments related to bitcoin, as well as developments in what I'll refer to here as "power ecology," and a description of some bitcoin projects to help the homeless.

Bitcoin Privacy Developments

There are several bitcoin privacy developments you should be aware of that are maturing significantly.

1) Peter Todd mentioned on Jan. 5, 2014 to the bitcoin development mailing list that "CoinJoin, CoinSwap and similar technologies improve your privacy by making sure information about what coins you own doesn't make it into the blockchain, but syncing your wallet is a privacy risk in itself and can easily leak that same info."  He additionally stated in part, "It is often advantageous if blockchain queries can be efficiently spread across multiple servers to avoid allowing the attacker to correllate the information into a whole. (...) With bloom filters doing this (it) is extremely costly as the full blockchain data needs to be read from disk to apply the filter; with prefix filters if the nodes have appropriate indexes there is little overhead to splitting the queries and no performance loss. (...) If addresses associated with change txouts are truly one-time-use, we can reduce or eliminate queries associated with them."

2) On Jan. 6, 2014, Peter Todd released an e-mail titled "Stealth Addresses" to the bitcoin development mailing list.  In this e-mail, he stated in part: "A Stealth Address is a new type of Bitcoin address and related scriptPubKey/transaction generation scheme that allowers payees to publish a single, fixed, address that payors can send funds efficiently, privately, reliably and non-interactively. Payors do not learn what other payments have been made to the stealth address, and third-parties learn nothing at all. (both subject to an adjustable anonymity set) (...)
Credit goes to ByteCoin for the original idea. Gregory Maxwell, Adam Back, and others on #bitcoin-wizards contributed valuable input on the implementation. Finally thanks goes to Amir Taaki for input on the
general idea of stealth addresses and use-cases."

3) Also on Jan. 6, 2014, Amir Taaki released new versions of libbitcoin, obelisk, and sx.  These releases are significant not only because these tools were used to develop Dark Wallet (on github in development here), but because they can (independently or jointly) be used for any privacy initiative relating to decentralized protocols.  From his e-mail announcement to the unSYSTEM mailing list (in part):
"This marks the first major release of Obelisk and SX. The version number
of libbitcoin has been bumped to 2.0, and I recommend everyone to
upgrade. This release has important bug fixes and code quality
"These packages will be maintained for some time, with bug fixes
backported. I'll also help with upgrading code to newer versions as the
API changes (just send me a message)."

The sha256sum of tarballs for this project were described in the e-mail as follows.  (The link to the source code on github is shown in hyperlinks provided earlier in this post.)


Power Ecology, Helping the Homeless

4) 'Power ecology' in the context of bitcoin is simply my way of describing shorthand the desire of many people to see bitcoin energy consumption be addressed in an ecologically sound manner.  While there are arguments that ecological concerns about bitcoin power use are essentially myths, it should be pointed out that there is no reason why we should not seek renewable sources of energy for bitcoin mining and maintenance.  Additionally, open source hardware intended to support production of sufficient renewable energy for bitcoin generation is a technology that already exists, and people have also built systems themselves to support such endeavors.  Such systems (whether offered for sale or built as "DIY") are not very expensive, considering the potential for the value they can produce.

5) Bitcoin Across America is a newly-released joint initiative involving Sean's Outpost and KryptoKit.  This is an effort to raise awareness about homelessness in the USA.  I hope you will support Bitcoin Across America with your donation.

See you next Tuesday.

features (as quoted from the Coinbase blog post on the subject):  
"The new Android SDK allows you to:
  1. Accept bitcoin payments from within Android apps - the customer never needs to leave the app to pay.
  2. Accept payments with zero transaction fees, and just a few taps for seamless checkout.
  3. Perform micro-transactions on mobile with zero fees.
  4. Initiate debit payments in bitcoin, and support other payment flows which weren’t possible previously using bitcoin."

Implications of License Approaches for Giving Economy and New Social Good

Well, one thing is certain if you are analyzing licensing options when developing anything that is intended to foster a "giving economy" and a new social good:  Your head is going to hurt.

"It seems to me this is the culmination of three prior digital disruptions... One of which is commerce going digital, the second is peer-to-peer exchange going mainstream... The third is the digitization of social. (...) (This) has started to bring online some of the real-world assets, like reputation, like histories, like social capital, that will be the trust infrastructure for the sharing economy."
(...) "(R)egulation perhaps can be supplanted or supplemented by these digital institutions."
- Arun Sundararajan, professor and NEC Faculty Fellow at New York University's Stern School of Business, speaks about a "sharing economy" and "digital disruption" at Techonomy 2012. 

Based on the record of software development in particular, there is strong evidence that the license approach that you choose, apart from the merits of your proposal, can (in many situations) make or break your project in terms of its potential to be used widely.

For example, Microsoft's NetBSD for eMIPS (which refers to a "dynamically extensible processor" - a mechanism for building and developing a processor or providing machine instructions) has a license which is known as a 2-clause BSD license (see more information on BSD licenses here).  In 2011, the NetBSD project adopted Microsoft's eMIPS port. Such licenses are highly permissive, which enables use of code in almost any way so long as copyright notices are conveyed with it.

Bitcoin, which has the highest market capitalization of any decentralized protocol utilized as a cryptocurrency, is released under what is known as the MIT License. That license is considered to be compatible with the GNU General Public License described below, but what developers want to do with the software they are developing will influence what sort of licenses they choose (in terms of MIT versus GNU General Public License) as well as influencing the circumstances in which the license(s) will be applied.

The GNU General Public license scheme, and some others that are similar, are detailed here.  This license also relies upon the copyright concept, although it utilizes the "copyleft" concepts to help ensure free use of the software regardless of whoever uses it.  This approach is not as permissive as the BSD license, and was successfully used for many software projects, including Linux (GNU/Linux).  In 2008 alone, GNU/Linux was thought to have resulted in revenue that was approximately equivalent to nearly $36 billion USD.  The Linux kernel was used to build Android, which is now used for over 80% of the mobile phone market (by any measure, the market is currently dominated by Android).

Copyright-dependent licensing schemes are not the only options out there.  There are, for example, systems which exist that are intended to coexist with copyright law, while generally rejecting modern notions of intellectual property.  One such example is the Unlicense, which has been used for many projects.

These are just a few examples of licenses used in software development, but further complicating the issue is that multi-licensing or dual-license concepts can also be employed.

The licensing approach has significant implications for modern developers of the giving economy and any new social good.  The terms you use and the licensing approach you choose are significant considerations that must be given serious thought in any endeavor intended to promote a 'sharing' or 'giving' culture.

What, Exactly, does Decentralization Change?

Decentralization in many parts of the world is increasing (see, for example, this recent study published in the Journal of Public Deliberation on the development and politics of subnational decentralization).
Some studies have examined decentralized versus centralized markets, and have shown, for example, that in certain conditions, a decentralized market is more efficient than a centralized marketplace.  Decentralized markets generally produce superior outcomes in the context of surplus when friction is reduced, or exists at a minimal level, and is small.  This raises the question of how "frictions" should be evaluated in the information economy, and suggests that "official attempts to manage economics" should be reduced wherever possible.  Organizations - including governments - that fail to either implement or adapt to decentralization will be absorbed by individuals, associations, and firms that demonstrate capacity to navigate an increasingly decentralized society.

Here I am not speaking of administrative decentralization, but rather a larger view, which includes political, fiscal, economic, and even personal and familial identity decentralization.   In this larger view, individuals and associations are empowered by their new-found realization that they can, merely through collective participation in the decentralization of financial systems (including individuals' and collective choices as to what we will fund in a giving economy), do away with most of what has traditionally been accomplished by government - and either continue it through funding of certain activities, or discontinue it by not funding others.  This also affects how people will in the near future develop the internet itself.  Broken trust in the common Certificate Authority (CA) system means more people will be turning to decentralized and open source solutions (such as TACK) to alter or replace the standard CA system, which until now has been assumed to be "just how things are done on the internet."

Wherever a potentially beneficial result occurs from government policy, such as reducing the potential for economic collapse via implementation of the Volcker rule, there should be maximum flexibility granted to innovators and participants in the new economy.  It should be understood that as part of this process, not only will some governments disappear and be replaced by  new organizations (or be done away with entirely in the transition to a new civil society), but as well, traditional financial institutions will eventually fade.  A good area to examine these developments is in the decline and death of banks as we understand them today.  The transition to a decentralized economy is accelerated by development of privacy enhancements (to the extent that those enhancements also spread in a free, open source, and decentralized fashion, which reduces the previously mentioned frictions).  These enhancements are now beginning to be implemented in not just one, but various decentralized currency protocols, which marks a historic point in what could be described as a revolution of purchasing power imparted to the individual.

"Bitcoin is really that revolution... I call it the seed of the resistance."  - Max Keiser

And that's all for this week, folks.  See you next Tuesday (that's a promise.)

"One of the problems that decentralization solves... is the difficulty of information moving around within centralized systems... Instead of... giving money to a central group of individuals... the best thing is to actually go to the source itself.... Instead of going to a centralized point.... you go to specific points and you've done away with a big part of the knowledge problem...."

Crypto Diversification & New Public Good

If you've been watching decentralized virtual currency developments at all over the past week or so, you've run into some interesting news.  Litecoin has shot up again, edging over $37 USD per LTC on the btc-e exchange as of the time I'm writing this post, and is approaching $39 (well over 241 CNY) on the OKC exchange. (Note: by the time this post was finished, litecoin was at over $40 USD on that exchange.)  In the process, jurisdictional arbitrage is providing users of various alt-coins with newly found wealth, even if they are not cashing out to their fiat currency of choice.  Five days ago, news broke in Forbes describing litecoin breaking the billion dollar mark for market capitalization, with namecoin breaking a 100 million dollar mark. Four days ago, the Guardian talked up not one, not two, but nine alt-coins, including quarkcoin -- which has now increased by over 500% in value. (It's also dropped quite a bit in value and has generated controversy over early mining efforts.  You can track what's happening with quarkcoin in real time at Cryptocoincharts.)  That's a coin that can be mined just with your CPU, and word on the street is that in addition to the areas where quarkcoin (and many other alt-coins) can be traded at present (Cryptsy, Coins-e, Bter, and Btc38), it is anticipated that quarkcoin (and other lesser known coin not yet in currency pairs on most exchanges) will be traded on btc-e as well, beginning at some point between December 15 - 20, 2013.
Bill Still (who will film the Dec. 19 Keiser report on Dec. 16, 2013) does a pretty good job of explaining quarkcoin, and covers it in an interview with Kolin, one of the quarkcoin developers.  (Kolin has a perspective on bitcoin (referring to it as "fantastically centralized") that I don't agree with, since bitcoin is a decentralized protocol. However, I've put the video here, so you can decide what you think. In my view, we will see development of many more coin types in the near future, and people who watch these developments closely, enter new markets early, and trade out at the right times, will be well-positioned to benefit.)

You would be right if you are thinking that you should engage in some 'crypto diversification.'  Beyond bitcoin, the march of decentralization has led to a proliferation of protocols, and huge surges of interest in the same.  But what about that new public good and the corresponding protocol development I alluded to in the prior post?  And, what are some ways to easily mine - to produce for yourself - namecoin, quarkcoin, and the like?

Living in Interesting Times: Decentralization becomes the rage, something new is released upon the world

At the risk of sounding cliché, I'll say it:  We are living in interesting times.

Decentralization has become the rage.  
The Pope (paradoxically, or not?) has championed decentralization.
People are sending bitcoins to charitable organizations in the Philippines, aiding recovery from Typhoon Haiyan.  Decentralized and open source search, content curation, and operating systems are becoming more popular.  And so on.

What to make of this?  So that you can get a good understanding of the implications of decentralization in today's world (and why many people have been championing it for so long), below is shown a video in which Andreas Antonopolous, founder of RootEleven (and several other bitcoin-based businesses), explains what decentralization is and why it is beneficial:

"In a way, hierarchical systems are a solution to the problem of direct access to information, direct access to each other, and communication scarcity.  When the problem no longer exists, (a) centralization hierarchy is the wrong solution." - A. Antonopolous

Day 2, Senate hearings: Bitcoin climbs in use, Congress Fails To Comprehend Bitcoin (Again)

"Bitcoin is an open standard, an open protocol, and an open source payment network.  Nobody owns the network, and nobody controls the network.  All of the users collectively own the network, its rules, and its ledger."- from Statement of BitPay CEO Anthony Gallippi, before the Subcommittee on National Security and International Trade and Finance and the Subcommittee on Economic Policy of The United States Senate Committee on Banking, Housing, and Urban Affairs, during the hearing on 'The Present and Future Impact of Virtual Currency,' November 19, 2013 
"Now we are engaged in a great Civil War, testing whether that nation, or any nation so conceived and so dedicated, can long endure. (...) It is rather for us to be here dedicated to the great task remaining before us (...) that government of the people, by the people, for the people, shall not perish from the earth." - Abraham Lincoln, Gettysburg Address, Nov. 19, 1863 
As today's Senate hearing on virtual currencies began, bitcoin rose to $704 USD, and continued to climb.
