Blockchain as an emergent technology is quickly gaining ground as a decentralised distributed trustless database in the form of a linked-list data structure. The data is stored in blocks, each referencing the previous block right till the initial block in the chain, hence the name blockchain. This chain is immutable and irreversible.
Consensus protocols are the mechanisms used to ensure this immutability and irreversibility in a trustless distributed network. These protocols however are based on a percentage of peers in the network agreeing on the chain’s validity which does not guarantee data and chain accuracy and integrity, if the peers are malicious or faulty.
This research aims to investigate and subsequently develop an alternative that can provide this guarantee.
