Algorithm 1 Key Distribution Smart Contract (KDSC)

Input:$PuK$, $EList$ // $PuK$ is public key. $EList$ is information set of edge nodes in the network. Output: State of public key distribution. 1:$KdList$ // This list is used to store the public key distribution status. 2:for i to size($EList$) do 3:    $PuK\to EList\left(i\right)$ // Assigns public keys to edge nodes in the network. 4:    $KdList.Add\left(Stae\right(EList\left(i\right))$ // $Stae\left(EList\right(i\left)\right)$ is the status in which the current edge node distributes the public key. 5: end for 6: return $KdList$
