Blockchain technology offers incredible value and opportunity in delivering
secured, decentralized transactions but faces significant challenges as it relates to
scalability, which hinders adoption and use. As in the maturation of blockchain
technology, challenges related to its scalability are important for latest technologies as
they can affect scalability and efficiency. These types of challenges to scalability
generally emerge through increased user and transaction volumes and cause losses in
performance and efficiency as they pertain to a congested network, storage of data, and
speed in processing time. Additionally, traditional consensus mechanisms, like proof of
work, seamlessly create challenges as they pertain to amounts of computational power,
and other resources allow allocation associated with work completion. As we can
imagine, potential solutions have already emerged that help to mitigate overcoming
these challenges. Solutions related to Layer 2 scaling, such as side chains or payment
channels, add an alternative layer to the transaction applications and, theoretically,
increase throughput and financially through decreased network congestion. Sharding,
which splits the blockchain into smaller, more manageable segments, also improves
operational efficiency. Moreover, advancements in consensus algorithms, including
Proof of Stake and hybrid models, aim to boost scalability while optimizing resource
use. This research explores the primary scalability challenges faced by blockchain
systems. It reviews the cutting-edge solutions being developed to improve their
performance, ensuring that blockchain technology can effectively support the
increasing demands of a decentralized digital world.
