At the International Conference on Internet of Things and Intelligence System (IoTAIS) from 24 to 26 November 2022, Dr Craig S. Wright, inventor of Bitcoin, delivered the keynote address. His talk introduced Bitcoin SV as a scalable blockchain and thus also as a network protocol set up to be the optimal solution for IoT devices to communicate on a global scale.

Security
The integration of simple
systems in IoT-based
supply chain management
has failed to consider many
security and reliability
issues, such as within
sensor-based distribution.
Privacy
The requirementsfor IoT
solutions in any industry are
primarily based on low-cost,
secure systems. Centralised
infrastructure with
traditional client/server
cloud structures often
compromises privacy.
Standardisation
Current monitoring and
sensor systems, combined
with the lack of
development in electronic
data interchange (EDI) and
logistics bills, have led to a
wide fragmentation of
solutions and standards.

Multilevel IOT (MIOT)
Architecture
BLOCKCHAIN TECHNOLOGY AS A FOUNDATION FOR INDUSTRIAL IOT
The MIOT combines a
command-control hierarchy
with the use of a blockchain
network infrastructure.
MIOT users create their own
multilevel control hierarchy,
which includes client-server
and peer-to-peer
relationships.

Non-Interactive Bitcoin IP
Transaction Using IPv6
CGA(++)
BLOCKCHAIN TECHNOLOGY AS A FOUNDATION FOR INDUSTRIAL IOT
The procedure here is a
modification that takes
advantage of the beneficial
properties of IPv6 (and CGA).
To send a Bitcoin transaction
to a recipient who isn’t online
(non-interactively),the sender
can take advantage of the
imbedded authentication,
using a signature, in CGA++.

Domain Name Bitcoin
Payments Using
IPv6CGA(++)
BLOCKCHAIN TECHNOLOGY AS A FOUNDATION FOR INDUSTRIAL IOT
To send a payment to a
domain name rather than an
IPv6 CGA(++), the sender
simply adds an extra step in
the beginning of the
procedure to resolve the IP
address that maps to the
domain name required.
In the CGA parameters,there
is an extFields parameter
where an optional variable-
length field (default length 0)
can be added.
Client issues DNS query to
resolve the IPv6 (AAAA DNS
record) address mapping to
the required domain name.
Verify DNS record(s) – if
DNSSEC is being used.
Check that the domain name
in the DNS record matches the
domain name in the extFields
CGA parameter.
Procedure continues as with

Decentralisation: Forming the Edges of the Network
BLOCKCHAIN TECHNOLOGY AS A FOUNDATION FOR INDUSTRIAL IOT
The purpose of a blockchain lies in low-cost transactions.
Parties engage directly in an exchange or trade.
The system replicates servers to add resilience.
It is electronic cash.
Decentralisationinvolves pushing information to the edges.
The term ‘decentralisation’ refers to individuals being able to
exchange information and minority groups being able to act
independently.
Blockchain technology is not about decentralisation.It merely uses decentralisation.

Blockchain Technology &
Industrial IoT (IIoT)
BLOCKCHAIN TECHNOLOGY AS A FOUNDATION FOR INDUSTRIAL IOT
Integrating blockchain-
based technologies into IoT-
based systems will create a
more resilient and secure
system.
I. With the adoption of more secure systems based on
blockchain technology, peer-to-peer systems operating
across a distributed, resilient network will replace
traditional centralised models.
II. Simple technologies such as RFID can be integrated using
IoT bridges to create smart factories directly integrated
with retail and logistic systems.
III. The deployment of IoT systems will lead to new paradigms
of mass customisation and the integration of complex
device-based identity.
IV. Integrating both agents and distributed hash table (DHT)
databases linked and monitored for integrity against a
blockchain network can lead to a more resilient and secure
system.

Blockchain Technology & Industrial IoT (IIoT)
BLOCKCHAIN TECHNOLOGY AS A FOUNDATION FOR INDUSTRIAL IOT
IoT and IIoT systems can be implemented to run over
decentralised peer-to-peer architecture using advanced 5G-
based network technologies.
When linked to a single public network, the ability to integrate
simple authentication methodologies can reduce the power
consumption and computational overhead associatedwith such
devices.
Such integrationwould benefit global logistics and enable the
integrationof supply chain management,purchasing, accounting,
and sales applications to reduce cost and risk and increase
profitability.
For IoT-based systems tobe successful, simplified blockchain-based distributed control systems that leave verification to
external nodes must be created and implemented in a standardised manner.
