| Abstrak/Abstract |
Several studies have been carried out to improve
the blockchain's Proof of Work (PoW) consensus method
because it weakens its consensus latency. This is in addition to
the introduction of consensus mechanisms, ranging from Proof
of Stake (PoS) to Flexible Proof of Activity (PoA). However,
these mechanisms are unable to increase latency significantly.
In this study, an adaptive PoW framework design was developed
by applying multiple mempool, which impact differences in the
transaction speed of each transaction. The proposed method can
facilitate different levels of consensus difficulty in each
transaction. The difficulty level adjustment in PoW is based on
collected and processed transaction data to obtain the level of
importance in each transaction. The difficulty level in baseline
PoW is used as the maximum level of the developed adaptive
process, followed by their definition. Finally, higher difficulty
levels are assigned to more critical transactions and vice versa.
Therefore, the latency will increase as the consensus difficulty
level rises and vice versa. Initial simulation results showed that
when tested with 6,000 transaction data, the adaptive PoW
framework design can increase the average number of
transactions per second by up to 400%. |
