of the IoE, and their ownership and containment
varied as individual/personal, private-group, public-group,
commercial, and facility-network. The
cross-chain sublayer represents the cross-chain
representation of the facility-network as a service,
which ismade of cross-chains and an associate set
of blockchains. The properties associated with
cross-chain and blockchain are application, contract,
consensus, network, and data. All the main
and subcomponents of detail, concreteness,and
representation are defined in the semidetailed,
semiconcrete,and semiformalmanner.6

in two ways:
normative representation, also known as RA
shown in Figure 3, and non-normative representation,
i.e., high-level SA, as shown in Figure 4.
The normative representation is created using
the ArchiMate modeling tool. The normative
MSC
4 comprises three main layers: the physical
layer, smart city ECB layer, and DMC layer.
The physical layer maintains heterogeneous
IoE and end-use cases of the smart city. End-users
are city dwellers of city A. Use cases described in
Figure 2 dominate this layer. The DMC layer provides
cloud infrastructure for smart city solutions,
which is briefly discussed in the " Preliminaries
and Motivation Scenario " section. The smart city
ECB layer is responsible for the smart city's multifactor
aware (security, privacy, scalability, and
cross-communication) cloud service platform.
This layer comprises the IoE ownership sublayer
and the cross-chain sublayer.
The IoE ownership sublayer represents both
ownership and containment of IoE devices. Heterogeneous
IoT and IoRT are the building blocks

DEDUCE SA FOR SCENARIO 1
This section presents the reasoning model
and derived SA for the proposed scenario 1. The
" Reasoning MSC
3 and MSC
4 for Scenario 1 " section
presents the reasoning abstraction for smart
city, and the " SA for Smart City Scenario 1 "
section delineates the proposed SA.

and MSC

As we discussed in (30.c), the smart city layer of
3 comprises twomain sublayers, which are
IoE ownership and cross-chain.Equations (30.c.1)
and (30.c.2) are adapted to comply with scenario 1.
IoE ownership values individual, private-group,
public-group, commercial, and facility-network of
(30.c) are, respectively, substituted by personalnetwork,
home network, public-network, office
network, and city-network as shown in (30.c.1).

According to (30.c) and the model described
in the previous section, the end-user has the
freedom to decide the values of the variables
(cross-chain, blockchain, and their properties).
According to (30.c), the IoB sublayer comprised
a cross-chain. The cross-chain is an emerging
trend and has played a significantly prominent
role in connecting multiple blockchains.18,19 Relay
techniques are the most common technique
behind cross-chain techniques, which connect
various blockchains and build IoB ecosystems.
Polkadot and Cosmos are two key representatives
in the cross-chains domain.20,21 Polkadot is
