Algorithm 13: Public block verification.

Input:

P u b B, C T_{n}, P P

.
Output:

T r u e o r F a l s e

.

1:
Confirm if $P r i B l o c k N o_{n}$ is available on private blockchain.
2:
$V e r i f y : B S i g ≟ σ_{C T_{1}} σ_{C T_{2}} \dots σ_{C T_{n}}$ .
3:
if above check holds, then continue with step 6.
4:
otherwise, terminate current session.
5:
Compute $h_{n} = H (C_{n})$ , based on $n$ log ciphertext $C_{n}$ .
6:
$V e r i f y : e (h_{i}, Y_{. x}_{n} C_{n}^{'}) ≟ e (B S i g, g_{n})$ .
7:
if verification holds, then output $T r u e$ .
8:
otherwise, output $F a l s e$ .
