Abstract: A closed-loop system is operatively connected with a block chain distributed network for using the block chain distributed network for facilitating operation of a transaction record sharing system. Host and source institutions function to supply a consolidated transaction record to a user in response to a request from a user to the host institution. The request is determined to meet a condition of the block chain thereby verifying the request. The verified request for a transaction record is transmitted to at least one source institution. The transaction record of the source institution is accessed by the host institution. A consolidated transaction record is communicated to the user based on the transaction record.

Abstract: Embodiments provide a system operatively connected with a block chain distributed network and for using the block chain distributed network for facilitating a person-to-person (P2P) alias-based payment. Embodiments receive a transaction record associated with a P2P transaction between a payor and a payee, wherein the transaction record comprises an alias associated with the payor and/or the payee; access a distributed ledger, wherein the distributed ledger is updated based on communications from a block chain distributed network; retrieve an alias to entity mapping from the accessed distributed ledger, wherein the alias to entity mapping indicates at least an entity to which the alias is mapped; and based on the mapping, determine that the alias is at least partially valid. In some cases, embodiments determine that the alias corresponds to an account number maintained by the entity in a private ledger; and authorize a transaction associated with the transaction request.

Abstract: Embodiments provide a system operatively connected with a block chain distributed network and for using the block chain distributed network for mapping aliases. Embodiments create an alias-token pair linking an alias associated with a customer to a token associated with an account owned by the customer; and map the alias-token pair to an address associated with the customer on a directory services (DS) block chain. In some cases, the system manages alias-token lifecycle including enabling editing and deleting the alias-token pair mapped to the address. In some cases, the system registers the address of the customer with the DS block chain. Such registering may include receiving a selection from the customer regarding desired node for registering the customer address; connecting with the DS block chain; and creating an account associated with the customer including creating a unique address associated with the customer and registering it with the DS block chain.
