The shared ledger has the following characteristics, except for the following

a. Is permissioned, so participants see only those transactions they're authorized to view. Participants have identities that link them to transactions, but they can choose the transaction information that other participants are authorized to view

b. Transactions are added to the blockchain after permission is obtained by the primary node

c. Records all transactions across the business network; the shared ledger is the system of record, the single source of truth.

d. Is shared among all participants in the network; through replication, each participant has a duplicate copy of the ledger.
