Abstract

A server in a blockchain distribution network includes a processor and a transceiver operatively coupled to the processor. The transceiver is configured to receive bytes of an encrypted blockchain from a peer node in a peer-to-peer network, where the server is unable to identify a source node that generated the encrypted blockchain based on the received bytes. The transceiver is also configured to propagate the bytes of the encrypted blockchain to one or more additional peer nodes and to one or more additional servers in the blockchain distribution network.

Claims (26)

1. A server in a blockchain distribution network, the server comprising:

a processor; and

a transceiver operatively coupled to the processor and configured to receive bytes of an encrypted blockchain from a peer node in a peer-to-peer network, wherein the server is unable to identify a source node that generated the encrypted blockchain based on the received bytes;

wherein the transceiver is configured to propagate the bytes of the encrypted blockchain to one or more additional peer nodes and to one or more additional servers in the blockchain distribution network;

wherein the transceiver is configured to receive an encryption key from the peer node, wherein the encryption key enables decryption of the encrypted blockchain; and

wherein the encryption key is received after the transceiver propagates the bytes of the encrypted blockchain to the one or more additional peer nodes and to the one or more additional servers in the blockchain distribution network.

2. The server of claim 1 , wherein the source node that generated the encrypted blockchain comprises the peer node.

3. The server of claim 1 , wherein the peer node comprises a first peer node and the source node comprises a second peer node that is different from the first peer node.

4. The server of claim 1 , wherein the encryption key originates from the source node.

5. The server of claim 1 , wherein the transceiver is configured to propagate the encryption keyto the one or more additional peer nodes and to the one or more additional servers in the blockchain distribution network.

6. A method of propagating information in a blockchain distribution network, the method comprising:

receiving, by a transceiver of a server in the blockchain distribution network, bytes of an encrypted blockchain from a peer node in a peer-to-peer network, wherein the server is unable to identify a source node that generated the encrypted blockchain based on the received bytes;

propagating, by the transceiver, the bytes of the encrypted blockchain to one or more additional peer nodes and to one or more additional servers in the blockchain distribution network; and

receiving, by the transceiver, an encryption key from the peer node, wherein the encryption key enables decryption of the encrypted blockchain, wherein receiving the encryption key occurs after the transceiver propagates the bytes of the encrypted blockchain to the one or more additional peer nodes and to the one or more additional servers in the blockchain distribution network.

7. The method of claim 6 , wherein the source node that generated the encrypted blockchain comprises the peer node.

8. The method of claim 6 , wherein the peer node comprises a first peer node and the source node comprises a second peer node that is different from the first peer node.

9. The method of claim 6 , wherein the encryption key originates from the source node.

10. The method of claim 6 , further comprising propagating, by the transceiver, the encryption key to the one or more additional peer nodes and to the one or more additional servers in the blockchain distribution network.

11. A peer node in a blockchain distribution network, the peer node comprising:

a processor configured to generate a blockchain that includes information regarding a plurality of transactions;

wherein the processor is configured to encrypt the blockchain; and

a transceiver operatively coupled to the processor, wherein the transceiver is configured to propagate bytes of the encrypted blockchain to a second peer node that is in communication with a server of the blockchain distribution network,

wherein the transceiver is further configured to propagate an encryption key that is able to decrypt the encrypted blockchain,

wherein the transceiver is configured to receive an indication that the encrypted blockchain has been distributed throughout the blockchain distribution network, and wherein the encryption key is propagated responsive to the indication that the encrypted blockchain has been distributed throughout the blockchain distribution network.

12. The peer node of claim 11 , wherein the encryption key is propagated to the second peer node.

13. The peer node of claim 11 , wherein the encryption key is propagated to the server of the blockchain distribution network.
