ECLB: Edge-Computing-Based Lightweight Blockchain Framework for Mobile Systems

Table 2

Advantages and disadvantages of some existing works.

Research	Advantages	Disadvantages
[10]	Make each end device to maintain a fragmented ledger, to reduce the storage pressure	Does not consider improving the transaction throughput and confirmation latency
[11]	Offload the computation-intensive mining tasks to nearby edge-computing nodes
[12]	Disburden the data processing tasks and mining tasks from end devices to edge servers
[13]	Employ a leader group to optimize the transaction throughput and confirmation latency	Does not consider reducing the ledger storage pressure at end devices
[14]	Decouple Bitcoin’s blockchain operation into leader election and transaction serialization to achieve scalability
