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

Algorithm 1

Candidate Tx block generation.

	Input:
	: The set of new transactions;
	: Hash of previous block header;
	: Timestamp;
	: Secret key of the leader;
	Output:
	: Candidate block;
(1)	Select a set of valid transactions from , denoted as ;
(2)	Set ;
(3)	Construct a Merkle hash tree over , and denote its root hash as ;
(4)	Increase by , where represents the block height and sets zero in the genesis block;
(5)	Compute a signature ;
(6)	Set ;
(7)	Set ;
(8)	return ;
