Declarations under Rule 4.17: as to the applicant's entitlement to claim the priority of the earlier application (Rule 4.17(iii)) (54) Title: LINKED MULTIPLE BLOCKCHAIN SYSTEM (57) : Embodiments of the disclosure are directed to areal-time pay- ments settlement system based on distributed ledgers, which may be imple- mented with blockchain technology. The distributed ledgers may be separate and distinct and each ledger can be used to track, record, and settle transac- tions between users of a pool account. The ledgers may also be interconnect- ed with one another by being connected to a main ledger, and this network of ledgers can be used to track, record, and facilitate settlement of transac- tions between users of different pool accounts that are associated with dif- ferent ledgers. This provides redundancy, transparency, and data access con- trols, while enabling multicurrency, cross-border transactions to be quickly verified, performed, and settled on a per-transaction basis while reducing the capital requirements of its users.
