The blockchain, dubbed the "new technological trend" by PWC1, is growing in popularity. According to IDC,
global investment in this innovative technology is expected to reach $2.1 billion in 2018.2 Worldwide,
Companies are exploring how best to use blockchain to increase confidence in their business value chains
and address key challenges related to complexity, transparency and security.
Did you say Blockchain?
Blockchain technology allows several parties to reach agreement on the authenticity of a transaction in a decentralized manner. These results are then recorded permanently in a shared database called blockchain, which is cryptographically secure.
Since the blockchain register is shared by all participants, no one has exclusive ownership over the data that is stored on the blockchain. Therefore, this data cannot be changed. Several blockchain configurations are used today and use different methods to reach an agreement or consensus, depending on the type of blockchain network. For example, one of the best-known blockchains, Bitcoin, functions as an unauthorized network in which everyone can participate. Many companies choose to operate a blockchain in which only known authorized entities can participate, as this model provides greater confidentiality, faster and more administrative tools to manage the network.
The real innovation of the blockchain is its ability to
automate trust between the parties who use it. The
transactions are settled collectively and retained in the
distributed register, eliminating the need for an intermediary
to create a relationship of trust. Participants can
use the blockchain as a source of trust rather than
to find an agreement between them.
What motivates the blockchain revolution?
The growth of the API economy has transformed the way we use technology in business. However, if technology
has come a long way, Internet commerce has not kept pace. Increasingly, today's businesses need to manage data
transactions between a large number of unreliable parties, which is a real challenge in terms of transparency,
complexity and security.
Blockchain-based technologies can create a foundation of trust in the company through the digitization of
business processes, tokenization of resources and the codification of complex contracts. These technologies can enable
ecosystems, made up of internal and external partners, interact and conduct transactions in full
without human intervention, making operations much more difficult for large companies.
How can we quantify this opportunity?
So far, institutions such as banks, banks, banks,
public authorities and large corporations managed the risks
to facilitate trade and commerce. Today, for

Ciscoblock® infrastructure contains the elements needed for a simple, secure enterprise blockchain
based on Cisco's proprietary technology. It consists of the following reference groups:
Cisco offers a blockchain platform (Figure 1) based on a modular architecture that allows implementations
to match the uses of different industries. This modular character allows services to be
updated over time, with new features, as blockchain technologies evolve. Exploiting
modern micro-service design models, this platform architecture helps to sustain the investment of a
company in the blockchain. The core of the platform consists of several layers, each with several services
many of them can be customizable with the help of snitable interfaces.
When evaluating any new enterprise blockchain solution, it is important to consider the ease of deployment
and network management, application development with quality tools and integration with existing systems. our
blockchain infrastructure includes interfaces that offer the functionality needed to achieve these goals, with more
great overall ease of use. Figure 2 details these interfaces.
Our blockchain infrastructure is hardware-independent and sets a set of standards to address the risks associated with
infrastructure security, including reference architectures to be deployed on site: in the Demilitarized Zone (DMZ) of a
in the cloud or through a hybrid deployment. In addition, the platform allows flexible support for a wide range of
infrastructure technologies, including hardware security modules (HSM) and WAN optimization tools such as SD-WAN.
A common misconception is that it is the distributed nature of blockchains that makes them secure. Without proper design, they can be exposed to several threats:
Our blockchain infrastructure is accompanied by end-to-end security and analytics functions, from the infrastructure layer to the interface layer. Additional protection is also provided by a blockchain application firewall (BAF). This firewall is similar to a web application firewall, which detects and blocks attack vectors by inspecting unusual patterns using
analytics. For example, a blockchain application firewall can detect unusual traffic from an agent that could represent an attempted denial-of-service attack. Analytics also measures blockchain network performance to ensure compliance with ALS and ensure that services work smoothly. Through its network security and application analytics leadership, Cisco is helping to redefine security and analytics for the corporate blockchain.
To Conclude
Blockchain technology can be a real
revolution through the automation of trust, the increase in
transparency and simplification of business processes.
However, in order to reach its full potential, it must rest
on a set of standards that meet complex needs
company. In addition, today's businesses are looking for
sector-specific solutions to transform their
business processes, and must be able to build business
interoperable blockchain networks.
Cisco lays the foundation for blockchain technology
companies, bringing together its strengths in terms of
architecture of high-availability distributed systems
as well as the best security features,
identity and cryptography. In order to accelerate the adoption of these
technology in the company, we are also a
ecosystem of partners and alliances capable of proposing
a true network of trust across the Internet.
