the title, after Monegraph tweets the link
to the image, it provides a block of code

Namecoin client. The user initiates a
new transaction in the Namecoin wallet
and adds the block of code as the key

validation against the Monegraph

A related digital art and copyright
protection project is Ascribe, which is
aimed at providing an underlying
infrastructure for IP registry. The
company is building what it calls an
“ownership layer” for digital property in
the form of a service to register and
transfer copyright. Although existing
copyright law offers creators protection
against infringement and the right to
commercialize, there is no simple,
global interface to register, license, and
transfer copyright. The Ascribe service
aims to address this, registering a digital
work with the service hashes and
timestamping it onto the blockchain. An
earlier step in the registration process
uses machine learning to detect and
resolve any prior-art challenges.
Ownership rights can then be
transferred, which enables secondary
markets for digital IP. The service
handles digital fine art, photos, logos,
music, books, blog posts, tweets, 3D
CAD files, and more. Users need no
prior knowledge of the intricacies of the
blockchain, copyright law, or machine
learning to benefit from the service. The
bulk of Ascribe’s users are marketplaces
and white-label web services that use
Ascribe in the background, though
individual users can use the site directly,
as well.
Digital Asset Proof as an
Automated Feature
In the future, digital asset protection in
the form of blockchain registry could be
an automatically applied standardized
feature of digital asset publication. For
certain classes of assets or websites,
digital asset protection could be invoked
at the moment of publication of any
digital content. Some examples could
include GitHub commits, blog posts,
tweets, Instagram/Twitpic photos, and
forum participations. Digital asset
protection could be offered just as travel
insurance is with airline ticket
purchases. At account setup with
Twitter, blogging sites, wikis, forums,
and GitHub, the user could approve
micropayments for digital asset
registration (by supplying a Bitcoin
wallet address). Cryptocurrency now as
the embedded economic layer of the
Web provides microcontent with
functionality for micropayment and
microIPprotection. Cryptocurrency
provides the structure for this, whether
microcontent is tokenized and batched
into blockchain transactions or digital
assets are registered themselves with
their own blockchain addresses.
Blockchain attestation services could
also be deployed more extensively not
just for IP registry, but more robustly to
meet other related needs in the
publishing industry, such as rights
transfer and content licensing.
Batched Notary Chains as a
Class of Blockchain
Infrastructure
It is important to remember that this is
only the outset of what could blossom
into a full-fledged blockchain economy
with blockchain technology enabling
every aspect of human endeavor, the
blockchain being like the Internet, and
the blockchain as the fifth wave of the
Internet. In this vein, it is possible that
all current blockchain-related activity
could be seen as early-stage prototypes
looking back from some future moment.
What are piecemeal services now could
be collected into classes of blockchain
services.
From the point of view of overall design
principles for the blockchain
infrastructure, we would expect to see
these classes of sector-specific
functionality arriving. Not just separate
blockchain notary services, but a new
class of notary chains themselves as part
of the evolving blockchain
infrastructure. Notary chains are an
example of a DAO/DAC, a more
complicated group of operations that
together perform a class of functions
incorporating blockchain technology. In
this case, this is the idea of notary chains
as a class of blockchain protocols for
attestation services. For example, it
might be more efficient to post batches
of transactions as opposed to every
individual transaction (requiring the
greater-than-zero mining cost). Notary
blocks could be composed of the hashes
of many digitally notarized assets; the
blocks themselves could then be hashed
so that the notary block is the unit that is
inscribed into the blockchain, making
more efficient use of the system rather
than every single digital artifact that has
been notarized. Because hashes are a
one-way function, the existence of the
block-level hash in the Bitcoin
blockchain constitutes proof of the
existence of the subhashes. 105 Moving
