Smart Contacts : We
all know that
the Blockchain technology
is the underlying platform for emergence
of Bitcoin and crypto
currencies. Because of
it’s secured distributed database
and associated philosophies like
immutability makes blockchain
a growing technology with the
increased adoption by various
verticals, especially finance,
Governement .
However the
industry finding the
biggest use of
Blockchain technologies in
the form of Smart
Contracts. Smart Contracts
are software defined version
of existing paper based contracts, in the sense that they are basically set
of compiled code
that runs inside a block chain network. By inheriting the qualities
of blockchain like
distributed leger,
cryptographically signed, immutability etc.. , smart contracts enable enterprises
to get into trust
based legal agreements
which reduces the cycle time of business operations
and reduce the cost of executing
them.
Consortium Blockchain
Network: As evident
blockchain technologies and
smart contracts facilitate the
execution of business agreements between two business entities, however in a
typical business use case there
are a set of
players that involve as stake holders with respect to that transaction. Hence it makes sense that
blockchain network is not
just built with 2 members, but
with a set of like minded organizations who are the stake holder in
that particular transaction. Some of the examples being.
·
Set of
financial institutions manage common
contracts like customer’s KYC
details or manage inter bank transfers to
prevent activities like money laundering.
·
Health care providers, insurance agencies, Government Welfare bodies share patient
treatment information to prevent fraud and to improve the quality of health care.
·
Manufacturing, Logistics, Part OEMs share supply chain related
smart contracts for best utilization
of inventory management.
At its simplest
form a consortium network is
also a Private
blockchain network, however considering the involvement
of selected stake holders it is
correct to use the term
Consortium blockchain network.
Smart Contract
Management Platform: As
enterprises adopt Blockchain in to their landscape,
especially with their participation in consortium
networks, they require
additional layer of management
solution on top of the
base blockchain layer. This
layer is termed
as “Smart Contract Management
Platform” (SCMP). A SCMP is
defied as a
additional layer on top of the
base underlying block chain
network, which provides a
business friendly features
for enterprises to
pilot,adopt, execute and
expand their smart
contract initiatives. SCMP also
help enterprises to add additional features and
usability aspects to
smart contracts which are
not available in the base technology
itself.
The following are
the key features
of a SCMP which
makes them useful
from an enterprise context.
One Enterprise Part Of Many Private Consortium: Due
to the very
nature of consortium blockchain
network consists
of interested stake holders, it is quite possible that one enterprise will
be part of multiple private consortium networks. For example
a health care provider may be part of a healthcare consortium to
share the patient treatment and
insurance claim information and at the same time the same enterprise can be part of a vendor
network that supplies
hospital equipment for better
transparency. There is no need
for these two
set of information exists in the
same blockchain network. However a SCMP can
help a health care provider to
manage both of these networks seamlessly. So that
business users can submit transactions,
view transactions, modify
transactions from any
of the networks that the organization
is part of.
Multiple Blockchain Platforms In Place:
Ethereum, Hyperledger,
Monax,Ripple to name a few are currently
available as blockchain platforms that
implement smart contracts
and this list can grow. There are no
uniformity in the application
interface and implementation of these platforms. Considering the point 1 above
with respect to one enterprise being
part of many private consortium,
this can further be complicated by the
fact that each of
these consortium can be implemented
using a different platform. SCMP can help
enterprises to adopt and
use multiple different platforms.
Smart Contracts are Inherently Complicated For Business Stake
Holders : The primary stake
holders of smart contracts are business people like CFO, Purchase Managers,
Government Regulators, Auditors and more,
however smart contracts in
itself are basically a
software code. And even in popular
platforms like ethereum, implementing
a smart contract involves bytecode, ABI, compilation and deploying them to
network. Also to get to the handle of a
existing contract, businesses need to
get to the hexadecimal address
for the
same. This means that
businesses cannot derive
and understand the
usage unless it is simplified. SCMP abstracts the technical complexities
of smart contracts and
provides a simple and easy to
use interface for
businesses to adopt.
More security controls needed in
smart contract, beyond what is
supported today : The programming languages and constructs for creating
smart contracts like solidity are evolving, which means that there may
be some limitations
which businesses cannot afford to
leave in their implementation.
For example ethereum
smart contracts have the concept of
addresses, which means that we
could restrict a smart
contract to be created only
by certain sender addresses. But how about
the need to have
further organizational controls
like Only CFO
within an organization can create certain financial
contract. SCMP can
help enterprises to
provide these additional layers
of security controls.
Off-chain meta data needed
for efficient usage
of smart contracts : As
smart contract is a legal
contract, it may not
contain meaningful comments
or tagging information which are
useful to search and
identify the smart contract itself. In
blockchain terminology, off-chain refers
to transactions and
events that occur
outside the blockchain network. By effectively
utilizing the Off-chain
concept a SCMP can store important
information that can be
useful in searching and other reporting operations on the block chain
itself. As with the current
implementation performing search
operations directly in the
blockchain platforms like ethereum
are quite complicated and hence the meta data assisted search
will simplify this
process.
Security Challenges In
the Current Block chain platforms
: As an
evolving technology, there are some inherent limitations in the
platforms which may
prevent its successful
adoption. For example
geth which is
one of client
implementations of Ethereum
block chain, exposes
a RPC end
point which can be taken
advantage by any
one to access the network.
Though the features like address level
security can prevent
certain things, it
is not fully
protected. SCMP can
help the enterprises to over come these
limitations with features
like IP Based
access security and avoidance
of RPC protocol etc…
Changes to Smart Contract and
Versioning : Due
to current limitation,
a smart contract which is
basically a set of
code, cannot be
changed once it is deployed. However in
practical scenarios there are always
needs for change. While the new versions
of smart contract
can always be
deployed, what about
transactions executed on the
old version of the code
and how about the
linking of those
records. SCMP can
provide options to
upgrade a smart
contract from version to a newer version.
Making Smart Contracts Really Smart : At
this point, smart
contracts don’t have intelligent beyond
what is programmed
in it. However
IoT and Machine Learning can be
integrated with smart contracts to
make them truly
smart. Imagine a
situation of a Purchase
Order payment contract is
fulfilled at a warehouse as soon as
the goods are received. SCMP facilitates integration
of smart contract with other technologies
like IoT and
Machine Learning. Similarly currently
self executing capabilities
of smart contract
are limited, however when
coupled with machine
learning smart contracts
can think of next
action and can
update accordingly.
Dynamic User Interface For Smart Contracts : A private consortium
network will keep evolving, which means
that new contracts
will be added,
existing contracts may be
renewed. Currently there are no options to
provide dynamic user
interface to contracts
without redeploying the user interface code. However SCMP can
attempt to provide
dynamic user interface to
smart contracts, so that addition
of new contracts
to the network will be seamless.
Infrastructure
Operations On Blockchain Network : While
the distributed nature
of block chain relieves enterprises
from traditional database
management tasks. There are some
tasks still needs to be performed, for
example in ethereum
block chain accounts need
to the exported and imported to be
available in new
nodes. Also several
network operations needs to
be performed when
adding a new
member to the
consortium. Azure Block Chain As a Service
and similar cloud providers
provide building blocks for
automating the infrastructure management
of block chain
platform. SCMP can
provide the automation
and infrastructure
management capabilities for
smart contract consortium network.
The above
are not the
complete list of
points that support
the need for a SCMP,
but definitely
they provide a
start.
