Algorithm 12: Public block calculation.

Input:

P r i B l o c k N o_{n}

.
Output:

P u b B

1:
Retrieve $P r i B l o c k N o_{n}$ from corresponding block $P r i B_{n}$ .
2:
Retrieve $σ_{C T_{n}}$ from $P r i B_{n}$ .
3:
Compute $B S i g = σ_{C T_{1}} σ_{C T_{2}} \dots σ_{C T_{n}}$ .
4:
Generate $P u b B = (P r i B l o c k N o_{n}, B S i g, O p t i o n a l F i e l d s)$ .
5:
Write $P u b B$ to public blockchain.
6:
Receive $P u b B l o c k N o_{n}$ from public blockchain.
