Systems and methods for processing blockchain transactions
A blockchain system has an identity-based blockchain account including a primary chain, a secondary chain, and at least one key book applying to the account, the at least one key book having a key page. The system includes: a hardware processor; and a memory device storing instructions. When the instructions are executed by the processor, they cause the processor to: record a multi-signature transaction originating from the account in the secondary chain; associate the transaction with the key page of the at least one key book, the key page including (i) a signature-authorization rule, and (ii) a plurality of keys corresponding to a plurality of transaction authorizers; record, in the secondary chain, an authorization of the transaction from a transaction authorizer of the plurality of transaction authorizers; and once a number of authorizations recorded on the secondary chain satisfies the signature-authorization rule, record the transaction on the primary chain for execution.

b) associating the multi-signature transaction with the key page of the at least one key book, the key page comprising (i) a signature-authorization rule, and (ii) a plurality of keys corresponding to a plurality of transaction authorizers, wherein each key of the plurality of keys of the key page of the at least one key book comprises one of (i) a hash of a transaction authorizer's public key, and (ii) a designation of a key-book authority;
c) recording, in the secondary chain, an authorization of the multi-signature transaction from a transaction authorizer of the plurality of transaction authorizers; and
d) once a number of authorizations recorded on the secondary chain satisfies the signature-authorization rule, recording the multi-signature transaction on the primary chain for execution,
wherein the identity-based blockchain account belongs to a first digital identity, and
wherein the designation of a key-book authority identifies one of (i) a supplemental key book belonging to the first digital identity, and (ii) an external key book belonging to a second digital identity.
2. The data management method of claim 1 , wherein the supplemental key book belonging to the first digital identity comprises a first manager key book for authorizing the multi-signature transaction based on a first characteristic of the multi-signature transaction and a second manager key book for authorizing the multi-signature transaction based on a second characteristic of the multi-signature transaction.
3. The data management method of claim 1 , wherein the external key book belonging to a second digital identity is identified via a uniform resource locator (URL) address.
4. The data management method of claim 1 , wherein the external key book belonging to a second digital identity authorizes the multi-signature transaction based on a set of rules of the second digital identity, thereby enabling an off-chain validation of a smart contract.
5. The data management method of claim 1 , wherein the at least one key book comprises a primary-layer key book and a secondary-layer key book, and wherein the secondary-layer key book enhances security of the identity-based blockchain account.
6. The data management method of claim 1 , wherein the key page is configured to allow replacement of at least one key of the plurality of keys, thereby enabling a dynamic key management.
7. A blockchain system having an identity-based blockchain account including a primary chain, a secondary chain, and at least one key book applying to the identity-based blockchain account, the at least one key book having a key page, the system comprising:
a hardware processor; and
a memory device storing instructions that, when executed by the hardware processor, cause the processor to:
a) record a multi-signature transaction originating from the identity-based blockchain account in the secondary chain;
b) associate the multi-signature transaction with the key page of the at least one key book, the key page comprising (i) a signature-authorization rule, and (ii) a plurality of keys corresponding to a plurality of transaction authorizers, wherein each key of the plurality of keys of the key page of the at least one key book comprises one of (i) a hash of a transaction authorizer's public key, and (ii) a designation of a key-book authority;
c) record, in the secondary chain, an authorization of the multi-signature transaction from a transaction authorizer of the plurality of transaction authorizers; and
d) once a number of authorizations recorded on the secondary chain satisfies the signature-authorization rule, record the multi-signature transaction on the primary chain for execution;
wherein the identity-based blockchain account belongs to a first digital identity, and
wherein the designation of a key-book authority identifies one of (i) a supplemental key book belonging to the first digital identity, and (ii) an external key book belonging to a second digital identity.
8. The blockchain system of claim 7 , wherein the supplemental key book belonging to the first digital identity comprises a first manager key book for authorizing the multi-signature transaction based on a first characteristic of the multi-signature transaction and a second manager key book for authorizing the multi-signature transaction based on a second characteristic of the multi-signature transaction.
9. The blockchain system of claim 7 , wherein the external key book belonging to a second digital identity is identified via a uniform resource locator (URL) address.
10. The blockchain system of claim 7 , wherein the external key book belonging to a second digital identity authorizes the multi-signature transaction based on a set of rules of the second digital identity, thereby enabling an off-chain validation of a smart contract.
11. The blockchain system of claim 7 , wherein the at least one key book comprises a primary-layer key book and a secondary-layer key book, and wherein the secondary-layer key book enhances security of the identity-based blockchain account.
12. The blockchain system of claim 7 , wherein the key page is configured to allow replacement of at least one key of the plurality of keys, thereby enabling a dynamic key management.
13. A memory device storing instructions that, when executed by a hardware processor, cause the hardware processor to:
a) record a multi-signature transaction originating from an identity-based blockchain account in a secondary chain of the identity-based blockchain account;
b) associate the multi-signature transaction with a key page of at least one key book applying to the identity-based blockchain account, the key page comprising (i) a signature-authorization rule, and (ii) a plurality of keys corresponding to a plurality of transaction authorizers, wherein each key of the plurality of keys of the key page of the at least one key book comprises one of (i) a hash of a transaction authorizer's public key, and (ii) a designation of a key-book authority;
c) record, in the secondary chain, an authorization of the multi-signature transaction from a transaction-authorizer of the plurality of transaction-authorizers; and
d) once a number of authorizations recorded on the secondary chain satisfies the signature-authorization rule, record the multi-signature transaction on a primary chain of the identity-based blockchain account for execution;
wherein the identity-based blockchain account belongs to a first digital identity, and
wherein the designation of a key-book authority identifies one of (i) a supplemental key book belonging to the first digital identity, and (ii) an external key book belonging to a second digital identity.
14.
