Regarding claim 2, 23, Tian discloses the method of claim 1, wherein the request includes register- transfer level data(Page 12 ¶ In an embodiment, the operator…”, the private key and details of mobile phone). Regarding claim 3. Tian discloses the method of claim 1, wherein the unique identifier is based on a tattoo associated with the first hardware device(Page 4 ¶ starting ” receiving a connection request…”, public key of terminal and mobile number is sent). Regarding claim 4. Tian discloses the method of claim 1, wherein the unique identifier is based on silicon(Page 4 ¶ starting ” receiving a connection request…”, public key of terminal, blockchain identifier and mobile number is sent). . Regarding claim 5. Tian discloses the method of claim 1, wherein the message contains an indication of the timestamp and the unique identifier(Page 4 ¶ starting ” receiving a connection request…”, public key of terminal and mobile number is sent). . Regarding claim 6. Tian discloses the method of claim 1, wherein the message is an SMS message(page 11 ¶ “In one embodiment, when terminal…”, mobile messages). Regarding claim 7. Tian discloses the method of claim 1, wherein the message is a machine-to- machine message(page 11 ¶ “In one embodiment, when terminal…”, mobile messages). . Regarding claim 8. Tian discloses the method of claim 1, further comprising generating a ledger identification associated with the blockchain stored on a distributed ledger(Page 8 ¶ “In the step S201,…”, blockchain identifier). Regarding claim 9. Tian discloses A method for providing exposure to a network, the method comprising: receiving a request for access to the network to send a message from a first hardware device, the message having computer readable information and comprising a timestamp associated with a time at which the request was received(Abstract & Page 4 ¶ starting “receiving a connection request…” , connection request with mobile number); responsive to receiving the request, generating a first block for storage on a blockchain(,(Page 9 ¶ starting “Step S204…”, block for blockchain), containing at least the timestamp, determining that the timestamp associated with the message corresponds with the time the request for permission was received(Page 12 ¶ starting “ In an embodiment, the operator broadcasts…”, time interval); and responsive to determining that the timestamp corresponds with the time the request for permission was received, communicating the message to a second hardware device(Page 9 to Page 10 ¶ starting “ Step S205, …”, the access verification result). .
