I lost interest in Bitcoin a while ago beyond occasionally ruing the
alt.fact that, after spending years and years paying attention to
cypherpunks+ lists, I guess I could have been one of the first few
hundred people to screw around with it. So what I say here is based
largely on happy ignorance about most of what's being claimed now —
or, if you like, based on a clearer understanding where it came from
rather than ___topian noise about where it's supposedly headed. Having
admitted that...
This avid-reader article seems like a flurry of angry complaints, many
based on unexamined assumptions.
Bitcoin began as a sort of thought experiment, more than anything else:
a proof of concept, driven more or less by the dictum that 'cypherpunks
write code.' That phrase itself was a reaction: the significant
distinction was that most people *don't* write code, or that they write
something other than code (laws, for example — hence Lessig's book
_Code_). The phrase first appeared in Eric Hughes's _Cypherpunks
Manifesto_ (1993), but that short essay had lots of other phrases in it
that didn't become world-changing slogans shouted by the same crowd who
brought you things like PGP, Wikileaks, BitTorrent, TOR, OpenSSL,
Signal, warrant canaries, etc. 'Cypherpunks write code' became the go-to
mantra on the cypherpunks mailing list as that list descended into
endless Hayekio-Vingean ranting and worse — it was basically the
list's in-joke way of saying 'STFU.' When the meta-meta-meta-ranting on
cypherpunks became too much, Perry Metzger started another mailing list,
'cryptography,' whose seemingly neutral name masked the implied polemic:
no 'punk' political noise. It was there some time later that Bitcoin was
first announced.

(Most nettimers know a bit about Hayek, but Vernor Vinge maybe not. His
sci-fi-fi writings were constantly invoked by the cypherpunks crowd —
mostly his novella _True Names_, but I think his space opera _A Deepness
in the Sky_ is more relevant in this context: the dialectic of
localizers.)

Bitcoin's success has led to a sort of Whig Interpretation of History
that hoovers up all kinds of anti/idealistic nonsense and obscures its
proof-of-concept origins. Those origins are important in this context,
now, because they can help us to cut through a lot of the current
Bitcoin ravings. This avid-reader essay is a pure expression of that
whiggish view: the author complains about pretty much everything
including the kitchen sink. In contrast, here's the abstract from
Satoshi's original paper proposing Bitcoin:
> Abstract. A purely peer-to-peer version of electronic cash would allow
> online payments to be sent directly from one party to another without
> going through a financial institution. Digital signatures provide part
> of the solution, but the main benefits are lost if a trusted third
> party is still required to prevent double-spending. We propose a
> solution to the double-spending problem using a peer-to-peer network.
> The network timestamps transactions by hashing them into an ongoing
> chain of hash-based proof-of-work, forming a record that cannot be
> changed without redoing the proof-of-work. The longest chain not only
> serves as proof of the sequence of events witnessed, but proof that it
> came from the largest pool of CPU power. As long as a majority of CPU
> power is controlled by nodes that are not cooperating to attack the
> network, they'll generate the longest chain and outpace attackers. The
> network itself requires minimal structure. Messages are broadcast on a
> best effort basis, and nodes can leave and rejoin the network at will,
> accepting the longest proof-of-work chain as proof of what happened
> while they were gone.

But, as they say, read the whole thing — it's just a few pages, and in
its bare-bones clarity its reads more like an IETF RFC than a
revolutionary manifesto. That suggests one useful way to understand
Bitcoin mania: it bears the same relation to the basic insight of
Bitcoin that pop debates about the alt.right relate to, say, RFC 1866,
'Hypertext Markup Language - 2.0.'
https://www.rfc-editor.org/rfc/rfc1866.txt
The *goal* of the Bitcoin proof of concept was 'an electronic payment
system based on cryptographic proof instead of trust, allowing any two
willing parties to transact directly with each other without the need
for a trusted third party.' So when the author of this avid-reader essay
complains 'but Visa... but FDIC... but NASDAQ,' one reasonable response
is: ¯\_(ツ)_/¯. The point of Bitcoin wasn't to succeed to the degree
that it has, or in the way that it has. Instead, it was a rough
prototype for a networked 'cash system' that wouldn't *necessarily
depend on* third parties to provide a bullet list of services that,
together, sketch out 'trust' as it's mostly experienced in consumer
society: processing transactions, mediating disputes, verifying
identities, defining and enforcing jurisdictions, and so on.
Now, obviously, the avid-reader author hopes to intervene in in the
popular madness of Bitcoin, so it makes sense for him (I assume him) to
spell out how and why it's less efficient / scalable than VISA, riskier
than FDIC-backed deposits, and all the rest. At the same time, though,
the project he announces is a bit different: showing that the blockchain
is rubbish.
Like everyone else, I don't know what'll happen with Bitcoin. Perry
Metzger recently did a very back-of-the-envelope calculation that for
Bitcoin to reach the million-dollar mark would require something like
the current global output of electricity — which seems like a hard
limit. But within that all I can say is that it seems to be the first
globally distributed ponzi-ish scheme. If that's roughly right, the good
news is that it'll turn out to be something like the AOL of digital
currencies. The bad news is that there are ~150 suckers born every
minute, and probably about as many new exotic financial products that
depend in some arbitrary, opaque, derivative way on Bitcoin's value
increasing. So a correction may take a while yet.
But none of that really has to do with the rough idea of a blockchain.
Indeed, if anything of enduring value comes from Bitcoin (aside from
massive 'creative destruction,' with all the human misery that'll likely
entail), I think it will be that very unsexy idea — which boils down
to little more than making it cheaper to make certain kinds of history
now than to forge it later on. Again, if Bitcoin didn't quite get that
right, ¯\_(ツ)_/¯. It's an RFC, a request for comments, and the
failures the avid-reader author lists off are comments. If it crashes,
that too will be a comment.
In itself, this isn't really a new idea, or at least it can be seen as
an incremental variation on the ancient idea of provenance: how do we
know where something comes from? The aim in Bitcoin is to make it easier
to verify the answer and harder to fake it. That's it. But history isn't
linear, and some 'increments' are more important than others. The key
difference in this case is the effort to make that real/fake distinction
easier to automate. I think that step toward automating that distinction
will turn out to be very significant. But not as a fetishized or even
noticeable thing in itself. Think of bar codes or PLU stickers on
agricultural products: we don't need to archive for all of eternity
where that avocado came from, we just need to know for limited purposes
in specific contexts to facilitate certain kinds of transactions at
particular points — which, as it happens, are cogs in a much deeper,
detailed, distributed negotiation between administrative structures and,
for lack of a better term, actual stuff.
But this is where the Hayekio-Vingean origins of Bitcoin matter:
whatever Satoshi's 'intent' was, Bitcoin was deeply informed by the
ideas of a milieu that was implacably hostile to 'trusted third parties'
— which mostly meant government and some of the peculiar commercial
creatures it enables (VISA, FDIC, NASDAQ, for example). Bitcoin was a
demo of an attack on a dominant global model of *trust*: a working-code
prototype of a system in which the end user — i.e., whoever would
accept BTC — is responsible for validating it. Blockchain-inspired
techniques will be widely implemented, I think, but in the social and
political context of systemic changes that shift more and more of that
function — assessing risk — away from 'government' and onto the end
user.
That's why, again, it's worth reading Satoshi's paper — it's clear
about one systemic weakness: 'The system is secure as long as honest
nodes collectively control more CPU power than any cooperating group of
attacker nodes.... If a majority of CPU power is controlled by honest
nodes, the honest chain will grow the fastest and outpace any competing
chains.... The incentive may help encourage nodes to stay honest.... As
such, the verification is reliable as long as honest nodes control the
network, but is more vulnerable if the network is overpowered by an
attacker.' And so on, again and again. It's remarkable — hilarious,
even — how often the word 'honest' appears in the paper, and how
deeply Bitcoin relies on 'honesty' without any serious effort to define
what it means. Normally, I wouldn't expect a writer to define such a
seemingly self-evident idea, but in the context of an effort to
dismantle trust we should probably make an exception.
It may well be that Bitcoin is based on sufficiently sound cryptographic
theory and practice that it'll remain secure against 'dishonest' attacks
*within* the system. In that case, Bitcoins may prove to have durable
value — maybe in the way that certain postage stamps have drifted from
everyday use to historical fetishists for hobbyists to collect. That's
not a prediction — again, I don't know. But as blockchain-inspire
techniques are integrated into general-purpose systems — again, with
limited purposes in specific contexts to facilitate certain kinds of
transactions at particular points — they won't have anything to do
with Bitcoin. And every one of them will be vulnerable to attacks from
'without' — outside of — their narrowly oriented focus. Some of them
will be quick-and-dirty thefts, others will be bogglingly long and deep
cons, and all of them will be vulnerable to 'dishonest' attackers
operating at every level from every perspective.
The standard responses to that kind of concern is 'the market will sort
it out,' but which market? The store where you buy an avocado is just an
immediate, tangible manifestation: as with PLU codes, behind them there
are markets upon markets upon markets that make that sticker useful:
meta-markets, meta-meta-markets, derivative markets, etc. These meta-
and derivative markets will define the values built into
blockchain-inspire techniques, and their main criteria will be how
effectively they shift risk-assessment functions onto the end user.
The author of the avid-reader essay asked 'What if, ten years after it
was invented, the reason nobody has adopted a distributed ledger at
scale is because nobody wants it?' One answer: who cares what you want?
The answer is *a lot of people* — but not for the same reasons you do.
Here's another way to think about what this might mean: a world of
honesty but without trust.
Cheers,
Ted
