Abstract: We claim: 1. A method for facilitating secure private transfers in a blockchain, comprising: receiving, by a receiver of a node in a blockchain network, an initiate message from a first computing device associated with a first participant system, wherein the initiate message 5 includes (i) an entity identifier associated with the first participant system, (ii) a transfer amount, and (iii) a private group identifier associated with a privacy group to which the first participant system and a second participant belong; identifying, by a processor of the node, a smart contract stored in the blockchain, using the private group identifier included in the received initiate message, said smart contract being 10 associated with the privacy group; executing, by the processor of the node, the smart contract using the received initiate message as input, wherein execution of the smart contract includes transmitting, by a transmitter of the node, an event message to an external central authority system including an entity identifier associated with the first participant system and transfer amount, said central 15 authority system maintaining balances for each participant system and providing authorization for a new entity to participate in the blockchain network as a participant system; and executing, by the processor of the node, the smart contract, wherein execution of the smart contract includes (i) adding a private blockchain transaction to the blockchain for transfer of the transfer amount from a first blockchain wallet associated with the entity 20 identifier to a second blockchain wallet in the privacy group associated with the private group identifier if the proposed private transfer is approved, or (ii) declining the proposed private transfer. 2. The method as claimed in claim 1, wherein the smart contract is stored in a 25 blockchain data entry in the blockchain that further includes the private group identifier. 3. The method as claimed in claim 1, comprising: receiving, by a receiver of the central authority system, the event message; 27 identifying, by a processor of the central authority system, blockchain wallet data associated with the entity identifier; determining, by the processor of the central authority system, approval or rejection of the proposed private transfer based on at least the blockchain wallet data and the transfer amount; 5 generating, by the processor of the central authority system, a response message including an indication of approval or rejection based on the determination; and transmitting, by a transmitter of the central authority system, the generated response message to the node. 10 4. The method as claimed in claim 3, comprising: transmitting, by the transmitter of the node, a notification message to the central authority including a notification of successful addition of the private blockchain transaction if the response message includes an indication of approval. 15 5. The method as claimed in claim 1, comprising: identifying, by the processor of the node, a specific privacy group profile of a plurality of privacy group profiles wherein a group identifier included therein matches the private group identifier included in the initiate message, wherein the second blockchain wallet is associated with a first of the two entity identifiers 20 included in the specific privacy group profile, wherein a second of the two entity identifiers matches the entity identifier included in the initiate message. 6. The method as claimed in claim 5, wherein the private group is associated with the specific privacy group profile. 25 7. The method as claimed in claim 1, wherein the private blockchain transaction is stored in a blockchain data entry in the blockchain that includes the private group identifier. 28 8. A system for facilitating secure private transfers in a blockchain, comprising: a blockchain network including a node and a plurality of additional blockchain nodes; a first computing device associated with a first participant system; and a central authority system that is external to the blockchain network, wherein the node includes a processor and a memory storing instructions thereon that, when 5 executed by the processor, cause the processor to: receive an initiate message from the first computing device, wherein the initiate message includes (i) an entity identifier associated with the first participant system, (ii) a transfer amount, and (iii) a private group identifier associated with a privacy group to which the first participant system and a second participant belong, 10 identify a smart contract stored in the blockchain using the private group identifier included in the received initiate message, said smart contract being associated with the privacy group, execute a smart contract using the received initiate message as input, wherein execution of the smart contract includes transmitting an event message to the central authority 15 system including the entity identifier associated with the first participant system and transfer amount, said central authority system maintaining balances for each participant system and providing authorization for a new entity to participate in the blockchain network as a participant system, and execute the smart contract, wherein execution of the smart contract includes (i) 20 adding a private blockchain transaction to the blockchain for transfer of the transfer amount from a first blockchain wallet associated with the entity identifier to a second blockchain wallet in the privacy group associated with the private group identifier if the proposed private transfer is approved, or (ii) declining the proposed private transfer. 9. The system as claimed in claim 8, wherein the smart contract is stored in a 25 blockchain data entry in the blockchain that further includes the private group identifier. 29 10. The system as claimed in claim 8, wherein the central authority system includes a processor and a memory, said memory storing instructions thereon that, when executed by the processor, cause the processor to: receive the event message, identify blockchain wallet data associated with the entity identifier, 5 determine approval or rejection of the proposed private transfer based on at least the blockchain wallet data and the transfer amount, and generate a response message including an indication of approval or rejection based on the determination; and transmit the generated response message to the node. 10 11. The system as claimed in claim 10, wherein the transmitter of the node transmits a notification message to the central authority including a notification of successful addition of the private blockchain transaction if the response message includes an indication of approval. 15 12. The system as claimed in claim 8, wherein the processor of the node identifies a specific privacy group profile of a plurality of privacy group profiles wherein a group identifier included therein matches the private group identifier included in the initiate message, and 20 the second blockchain wallet is associated with a first of the two entity identifiers included in the specific privacy group profile, wherein a second of the two entity identifiers matches the entity identifier included in the initiate message. 13. The system as claimed in claim 12, wherein the private group is associated 25 with the specific privacy group profile. 30 14. The system as claimed in claim 8, wherein the private blockchain transaction is stored in a blockchain data entry in the blockchain that includes the private group identifier.
