## Abstract

Various embodiments that pertain to an enterprise network that employs a block chain portion and a non-block chain portion. For a single transaction, a header of the transaction can be sent over the block chain network and the non-header of the transaction can be sent over the non-block chain network. A hash-based cuckoo filter can be used for communication of the header along the block chain network.

## Claims

### Claim 1

A system, comprising:
a network component configured to manage a block chain network with a block chain-based network architecture; and
a hash component configured to use a hash-based cuckoo filter for a transaction set for the block chain network,
where the network component, the hash component, or a combination thereof implement, at least in part, by way of non-software.

### Claim 2 (depends on 1)

The system of claim 1,
where the block chain network is part of an enterprise network,
where a non-block chain network is part of the enterprise network,
where the transaction comprises a header and a payload,
where the header is transmitted along block chain network, and
where a hash of the payload is transmitted along the non-block chain network.

### Claim 3 (depends on 2)

The system of claim 2, comprising:
a generation component configured to generate an encryption key set,
where the generation component is part of the block chain network and
where the encryption key set comprises a key set for communication of the header along the block chain network and a key set for communication of the hash along the non-block chain network.

### Claim 4 (depends on 2)

The system of claim 2,
where the enterprise network employs an algebraic consensus algorithm to find a hash value with regard to the hash-based cuckoo filter.

### Claim 5 (depends on 1)

The system of claim 1,
where the block chain network employs peer-to-peer session initiation protocol.

### Claim 6 (depends on 1)

The system of claim 1,
where the block chain network is a permissioned block chain network managed by an authority.

### Claim 7 (depends on 1)

The system of claim 1, comprising:
an evaluation component configured to evaluate the transaction set to produce an evaluation result; and
a classification component configured to classify the transaction set as filterable or non-filterable based, at least in part, on the evaluation result,
where when the transaction set is classified as filterable, then the hash component is configured to use the hash-based cuckoo filter upon the transaction set and
where when the transaction set is classified as non-filterable, then the hash component can be configured to not use the hash-based cuckoo filter upon the transaction set.

### Claim 8

A non-transitory computer-readable medium that is communicatively coupled to a processor and stores a command set executable by the processor to facilitate a component set, the component set comprising:
a block chain network component configured to send a header of a block over a block chain network; and
a non-block chain network component configured to send a non-header of the block over a non-block chain network,
where the block chain network and the non-block chain network are part of an enterprise network and
where the header of the block is encrypted by way of a hash-based cuckoo filter.

### Claim 9 (depends on 8)

The non-transitory computer-readable medium of claim 8, comprising:
