| dc.description.abstract | Distribute Ledger Technologies (DLTs)
provide a distributed and decentralized environment
with no central trusted control authority. DLTs
removes a single point of authorization hence
increasing the levels of trust of distributed records
however there are still challenges in the underlying
consensus algorithms, architectures and data
structures in DLTs applications that need to be
addressed. This paper employs exploratory research
design with an objective to review various literature
on different consensus algorithms, architectures and
data structures applied in DLTs applications. The
study revealed proof-of-work and proof-of-stake as
some of the common consensus algorithms used in
DLTs. The review shows that DLTs use either linear
or linked, complex and hybrid data structures.
Blockchain, Directed Acyclic Graph, Hashgraph,
Holochain and Tempo (Radix) as the common types
of DLTs. The findings also indicated that DLTs
architectural design is constructed of three layers
Protocol, Network, and Data. This study contributes
to body of knowledge in DLTs. | en_US |
