Algorithm 5 On-Chain Revocation Propagation

Require: revocation queue entry $({\kappa }_i,e_i)$ produced by Algorithm 1; ledger client for $\mathcal{L}$

1: $\mathsf{tx}\leftarrow$ SignskG$(\mathsf{revoke},{\kappa }_i,e_i)$

2: Submit $(\mathcal{L},\mathsf{tx})$

On event Revoked$(\kappa ,e)$ at any gateway:

3: ${\mathcal{R}}_{\mathrm{cache}}\leftarrow {\mathcal{R}}_{\mathrm{cache}}\cup \left\{\kappa \right\}$

4: EmitMetric $\left(\mathsf{revocationLatency}\right)$
