Research on Grain Food Blockchain Traceability Information Management Model Based on Master-Slave Multichain

Algorithm 1

Data judgment smart contract.

	Input: input collected data, Input Data (ID)
	Output: qualified data, Standard Data (SD)
(1)	count ID = n//The total number of input data is n
(2)	for ! n do
(3)	if ID ! = float32/float64
(4)	return null
(5)	else if
(6)	return SD
(7)	end for
