be considered
Operating policies Allows to operate and view the current state and history of all operations on the policy.
Reinforce product and geography specific business rules.
● Register an issued policy
● Policy Holder Withdrawal
○ during the cooling-off period (rétractation)
○ after the cooling-off period (résiliation)
● Renewal
● Billable endorsement
● Non Billable endorsement
● Suspend a policy (in case of unpaid invoice, for instance)
● Insurer cancellation (in case of missing or invalid supporting document or when the policy
holder have not kept to the terms of the policy or did not comply with anti-money
laundering/combating the financing of terrorism policy or other exceptions...)
(Only policies operated by Wakam are in the scope of to this context. It does not apply to the policies
operated by Wakam partners and reported to Wakam)

● Non Billable

● Event Sourcing
● CQRS

● Domain Event
● Fault Event

reconciliation
● Guarantees eventual consistency between ocPAS and the public blockchain
● Abstracts blockchain related complexity to the rest of ocPAS
● Auxiliary of Operating policy bounded context
in details:
● Allows formatting, signing and publishing blockchain transactions to the public blockchain
(the one associated to the partner) for each public domain event related to the lifecycle of
the insurance policy
● Notifies ocPAS of blockchain transactions published directly by the partner to the public
blockchain.
Public blockchain remains the source of truth.
When a partner publishes directly a transaction to the blockchain, the state may become temporarily
inconsistent because some business rules cannot be published to the blockchain (GDPR for instance).
However, this inconsistency should be compensated by ocPAS eventually.

& invoicing
● Monitors payments related to each policy.
● Establishes the payment schedule and issues receipts/invoices (Quittances).
● Manages reminders and anticipate the expiration of payment methods.
● Notifies all ocPAS as soon as an invoice is considered as unpaid.
In the same way, it notifies all ocPAS when an unpaid invoice gets paid.

Annual paid by Card (CB)

Stripe through Particeep tunnel
