Since the Bitcoin launch, the interest in Distributed Ledger Technologies
has grown over the years and its potential was soon perceived for several
applications. More recently, Smart Contracts and Decentralized Finance
Protocols emergence made room for new business models, in order to
provide more efficient settlement solutions and a better experience
for people through Digital Assets. The Central Banks and Financial
Regulators have been connected to this new context of the token
economy, introducing their CBDC’s initiatives and proposing regulatory
frameworks and models to provide security in the crypto environment.
The adoption of these new technologies in a financial environment
brings several challenges, due to the incompatibility of standards
used in the current centralized systems, demanding a great technical
strategy to provide interoperability and efficiency for the operations.
Considering this scenario, this paper proposes an architecture model to
connect legacy systems to the DLT platforms, describing the necessary
components and introducing a dedicated layer to abstract the network’s
characteristics, providing control, security and being agnostic and
transparent to the current channels and financial services
