6. The method of claim 1 , wherein the new contract, the whitelist including the list of atomic contracts which can be used with the new contract, and the blacklist including the list of atomic contracts which cannot be used with the new contract are verified by participants of the blockchain network on the blockchain network and added to the blockchain network upon approval by the participants.

7. The method of claim 6 , further comprising:

determining that the smart contract pipeline is available in the blockchain network,

wherein, when the smart contract pipeline is available, executing the smart contract pipeline.

8. The method of claim 1 , wherein the service request comprises at least one of a voice request or a text-based request.

9. An apparatus for managing a service request in a blockchain network, comprising:

at least one processor configured to:

identify at least one intent from a service request received by the apparatus,

establish a plurality of hierarchical levels each of which corresponds to the plurality of services based on the categorizing,

select a plurality of atomic contracts by filtering the plurality of atomic contracts with a whitelist and a blacklist, wherein each of the plurality of atomic contracts is a complete contract satisfying the at least one intent and corresponds to each of the plurality of services, and previously generated prior to the service request in connection with each of a plurality of second devices on the blockchain network and is verified in the blockchain network in response to a request similar to the service request, and wherein the whitelist is a list of atomic contracts which can be used with the each of the plurality of atomic contracts and the blacklist is a list of atomic contracts which cannot be used with the each of the plurality of atomic contracts,

determine whether at least one atomic contract, among the plurality of atomic contracts, is unavailable,

select an alternative atomic contract replacing the at least one atomic contract determined to be unavailable, based on the hierarchical level corresponding to a service among the plurality of services which is corresponding to the alternative atomic contract positioned at a same level in the hierarchical level as a service corresponding to the at least one atomic contract determined to be unavailable,

generate a new contract including the plurality of atomic contracts and the alternative atomic contract replacing the at least one atomic contract determined to be unavailable,

determine whether a smart contract pipeline is available in the blockchain network, and

in response to a determination that the smart contract pipeline is not available, deploy the smart contract pipeline in the blockchain network, wherein the smart contract pipeline is deployed by generating the smart contract pipeline including the plurality of atomic contracts and the alternative atomic contract by putting the plurality of atomic contracts and the alternative atomic contract in sequence, parallel or hybrid combinations; and

a transceiver for broadcasting the new contract, the whitelist including a list of atomic contracts which can be used with the new contract, and the blacklist including a list of atomic contracts which cannot be used with the new contract, over the blockchain network.

10. The apparatus of claim 9 ,

wherein the at least one processor is further configured to:

determine the at least one service request item or the at least one attribute, by parsing a statement included in the service request; and
