Invention Patent Descriptive Report for METHOD AND SYSTEM OF USE OF DIGITAL SIGNATURES TO SIGN BLOCKCHAIN TRANSACTIONS.
CROSS REFERENCE TO RELATED PATENT APPLICATIONS [001] This patent application claims priority and benefit from the filing date of US patent application, serial number 14 / 976,331, filed on December 21, 2015, which is incorporated here at its entirety by reference.
TECHNICAL FIELD [002] The present invention relates to the use of digital signatures to sign Blockchain transactions, more specifically, the use of digital signatures by multiple entities in the signature and validation of Blockchain transactions to increase security and make validation more efficient.
BACKGROUND [003] Blockchains are used as a public fiscal book for electronic transactions. Each new transaction block added to the Blockchain provides additional validation of the previous blocks, which makes the Blockchain increasingly solid over time. As old Blockchain blocks never change and Blockchain neither loses nor discards old blocks, Blockchain becomes an immutable, yet publicly accessible record of all transactions. Blockchains can also offer additional benefits that encourage their use in conducting electronic transactions, such as anonymity and security.
[004] To generate new blocks, several Blockchains depend on an extensive computational capacity that uses a dispersion algorithm combined with brute force search to generate a hash function that corresponds to the previous block on the Blockchain. For

2/43 encourage participation in the search, Blockchains generally allow the participation of any user with any suitable computing device and also offer a reward to the user who can find a suitable hash value. As more users participate and computing capacity increases, Blockchains can cope with increasing energy expenditure and computing capacity.
[005] Thus, there is a need for a technical solution whereby new blocks can be generated for the Blockchain, which are reliable and safe, but which do not result in significant computational and energy expenditure. The use of signatures by verified and trusted participants can ensure that the new blocks are reliable and safe, as well as allowing the blocks to be properly verified for inclusion in the Blockchain and require significantly less computational capacity. In addition, using only trusted entities, the group of participants can be limited, which can decrease the amount of energy spent on producing new blocks for the Blockchain. Thus, there is a need for a technical solution that uses a trusted group of participants and digital signatures to sign Blockchain transactions.
SUMMARY [006] The present invention provides a description of systems and methods for using digital signatures in signing Blockchain transactions.
[007] A method of using digital signatures to sign Blockchain transactions includes: generating, through a generation module of a processing server, a domain key pair comprising a private domain key and a domain key public, where the public domain key is signed after

DETAILED DESCRIPTION
Glossary of Terms [0020] Blockchain - A public fiscal book of all transactions in a Blockchain-based currency. One or more computing devices can comprise a Blockchain network, which can be configured to process and record transactions as part of a block on the Blockchain. As soon as a block is completed, it is added to the Blockchain and the transaction record updated. In several cases, Blockchain can be a fiscal book of transactions organized in chronological order, or it can be presented in any other order whose use is suitable for the Blockchain network. In some configurations, transactions registered on the Blockchain may include a destination address and an amount of currency so that the Blockchain can record how much currency is attributable to a specific address. In some cases, additional information may be captured, such as a source address, date and time,
Petition 870190010582, of 01/31/2019, p. 11/22
8/43 etc. In some modalities, Blockchain may also consist of additional data and, in some cases, arbitrary data that is confirmed and validated by the Blockchain network through proof of work and / or any other appropriate verification techniques associated with it. In some cases, such data may be included in the Blockchain as part of transactions, as included in additional data attached to the transaction data. In some cases, the inclusion of such data on the Blockchain may constitute a transaction. In such cases, Blockchain may not be directly associated with a specific digital and virtual approval or other type of currency.
Blockchain Transaction Signature System Using Digital Signatures [0021] Figure 1 illustrates a system 100 for the signature of Blockchain transactions by a trusted group of participants using verifiable digital signatures.
[0022] System 100 can include a signatory authority server 102. Signatory authority server 102, discussed in more detail below, can be associated with Blockchain and configured to digitally sign the Blockchain transaction blocks to be included in the Blockchain. In some cases, the Blockchain can be associated with a single server of the signatory authority 102, which can digitally sign each block that is added to the Blockchain. In other cases, the Blockchain can be associated with multiple signatory authority servers 102, each of which can be configured to digitally sign the blocks added to the Blockchain separately, either with simultaneous or redundant subscription. In the latter cases, different signatory authority servers 102 may have different keys for separate validation of the blocks respectively signed by the
Petition 870190010582, of 01/31/2019, p. 11/23
9/43 member systems, or they can use the same keys, with the resulting signed blocks having their accuracy compared and being validated by a member system or another signatory authority server 102.
[0023] System 100 may also include a plurality of member processing servers 104, illustrated in Figure 1, as member processing servers 104a and 104b. Member processing servers 104, discussed in more detail below, can be associated with Blockchain and can be configured to digitally sign Blockchain transactions and create blocks to be included in the Blockchain. Member processing servers 104 can also be configured to digitally validate signed blocks that were signed by other member processing servers 104 and / or signatory authority servers 102 prior to their inclusion in the Blockchain. As discussed here, signatory authority 102 servers and member processing servers 104 can comprise a Blockchain network, which can be interpreted by people versed in the relevant technique as referring to the systems and infrastructure used in the management and maintenance of the Blockchain. .
[0024] System 100 may also include a plurality of participant devices 106, illustrated in Figure 1 as the participant devices 106a, 106b, 106c, 106d, 106e and 106f. Each participant device 106 can be a computing device suitable for adding new Blockchain transactions to a member processing server 104, for inclusion in a new block to be added to the Blockchain. The computing device can be a desktop computer, a laptop computer, a notebook computer, a
Petition 870190010582, of 01/31/2019, p. 11/24
10/43 table, cell phone, smart phone, smart television, smart watch, wearable computing device, implantable computing device, etc. Participant device 106 can electronically transmit the data associated with a Blockchain transaction to a member processing server 104 to be launched on the Blockchain. The data transmitted to the member processing server 104 can be based on the type of transaction, Blockchain properties and other criteria, as well as include, for example, a source address, a destination address and a quantity of currency of Blockchain to be transferred. In some cases, multiple source addresses or destination addresses may be included, and a source address may be digitally signed by the participant device 106 for validation as an authorized user of the associated Blockchain currency.
[0025] For use in the digital signature of blocks and other data, the signatory authority's server 102 can generate a pair of domain keys. The domain key pair can consist of a private domain key and a corresponding public domain key. Domain keys can be used for signing blocks and other data, where the private domain key can be used to sign data and where the public domain key can be used (for example, by another entity, such as a member processing server 104) to validate or otherwise verify the signature. The domain key pair can be generated using any suitable algorithm for generating the key pair. Digitally signing data using the private domain key can use any suitable method for digitally signing data using a private key that is consistent with the functions discussed here.
Petition 870190010582, of 01/31/2019, p. 11/25
11/43 [0026] As soon as the domain key pair is generated, the signatory authority server 102 can have the public domain key signed. In some embodiments, the public domain key can be self-signed by the signatory authority's server 102. In some cases, the public domain key can be self-signed only if the signatory authority's server 102 and member processing servers 104 are part of a closed network used to access and / or send to associated Blockchain. In other embodiments, the public domain key can be signed by a public authority, such as a trusted third party configured to sign public keys. The trusted third party can sign the public domain key, the signature of which can be validated by one or more member processing servers 104 on the Blockchain network.
[0027] Each member processing server 104 can also generate a key pair, referred to here as a member key pair. Each member key pair can consist of a member private key and a corresponding member public key. In some embodiments, the member key pair can be generated using the same key pair generation algorithm used by the signatory authority's server 102 when generating the domain key pair. Each member processing server 104 can securely store its respective member private key and can electronically transmit its respective member public key to a server of the signatory authority 102 to sign it. Member public keys can be electronically transmitted to a signatory authority server 102 via overlay on a data signal that is transmitted using any suitable type of network or communication method, such as a local area network, a network of area
Petition 870190010582, of 01/31/2019, p. 11/26
12/43 wide, a wireless area network, radio frequency, Bluetooth, near field communication, the Internet, etc.
[0028] The signatory authority's 102 server can be configured to sign each of the public keys of members using the private domain key. Public keys of already signed members can then be returned to member processing servers 104 for later use in validating signed blocks and Blockchain transactions. In some embodiments, each member processing server 104 may receive a publicly signed member key from one or more different member processing servers 104 on the Blockchain network, such as for use in validating signatures made by one or more member servers processing of different members 104. In some cases, the signatory authority server 102 may also distribute the public domain key already signed to one or more member processing servers 104, for use in validating signatures made by the signatory authority's server 102 using the private domain key.
[0029] In some embodiments, the signatory authority server 102 can be configured to authenticate a member processing server 104 prior to the distribution of any key to the member processing server 104. Authentication of member processing servers 104 can be performed using the standard registration scheme whereby a member processing server 104 and / or the entity associated with it can register with the signatory authority's server 102 as a trusted server for use in digitally signing transactions. Blockchain. For example, a 104 member processing server can provide industry credentials, identification information, detailed
Petition 870190010582, of 01/31/2019, p. 11/271
13/43 device, etc. as part of the registration process for signatory authority 102, which can verify the authenticity of the data and register the server as a member processing server 104 on the Blockchain network to which keys can be delivered. In some cases, the signatory authority's server 102 may be configured to ascertain or otherwise determine the suitability of a processing server that is attempting to register as a member processing server 104 for use in the digital signature of Blockchain transactions. This determination can be based, for example, on the technology level of the processing server, on the security protocols being used by the server and on the computing system, associated internal network infrastructure, etc. In some cases, the signatory authority server 102 may restrict the number of member processing servers 104, such as to a trusted group of member processing servers 104 and of a limited size for security reasons.
[0030] After being registered and receiving the public keys of signed members and the public domain key signed, a member processing server 104 can receive the Blockchain transactions to be posted on the Blockchain. To generate a new block for the Blockchain, the member processing server 104 must search for a hash function that corresponds to the hash of the previous block in the Blockchain where the new block will be added. The member processing server 104 can map the previous block using one or more scatter algorithms suitable for obtaining a first hash value. The member processing server 104 can then fetch a second hash value that corresponds to the first hash value. The match can be exact (for example, when both hash values are
Petition 870190010582, of 01/31/2019, p. 11/28
14/43 equivalents) or can correspond in one or more different ways, such as when the second hash value is the inverse of the first hash value, when characters of the hash value are equivalent to a specific number, when the numbers of the last characters of the first hash value are equivalent to the number of the first characters of the second hash value, etc. Acceptable match can be based on a desired time frame for the search, a desired security level, preferences of the Blockchain network, etc.
[0031] After a suitable second hash value is found, member processing server 104 can sign the hash value using its private member key. And then, the member processing server 104 can electronically transmit a block composed of the Blockchain transactions and the signed hash value on the signatory authority's server 102. The signatory authority's server 102 can then sign the block using its private domain key. . The signatory authority server 102 can distribute the digitally signed block so that one or more member processing servers 104 can perform its validation. In some embodiments, the digitally signed block can be validated by a member processing server 104 other than the member processing server 104 from which the block originates. For example, in the case illustrated in figure 1, the member processing server 104a can provide the transactions and the signed hash value to the signatory authority server 102 and the signed block can be delivered to the member processing server 104b for validation. .
[0032] The member processing server 104 may use the signed public domain key, associated with the signatory authority server 102 that signed the block, as well as the key
Petition 870190010582, of 01/31/2019, p. 11/29
15/43 public member already signed that is associated with the member processing server 104 that signed the hash value to validate the block. The validation of the block can include the application of the public domain key already signed to the signed block using an appropriate dispersion algorithm to generate the transactions and the signed hash value, as well as the application of the public key of members already signed to the value signed hash to generate the unsigned hash value. The unsigned hash value can then be verified to be equivalent to the hash value of the previous block on the Blockchain to which the new block is to be added. Once the block is validated, the new block can be added to the Blockchain. In some embodiments, the block can be validated primarily by multiple member processing servers 104. In some cases, a new block can be validated by a participant device 106. In this case, the participant device 106 can receive the domain key public signature already signed and the public key of members already signed for use in validating the signed block as discussed above. In some cases, the member processing server 104 or the participant device 106 that performs the validation may also validate a public domain key trust chain certificate, such as that used in the signing of the public domain key by the third party trustworthy.
[0033] The methods and systems discussed here can provide the signature and validation of new blocks of Blockchain transactions on a Blockchain that can be performed using less computational capacity and reducing energy expenditure, while maintaining the same level of security used in existing Blockchain systems. With the use of digital signatures, the security and authenticity of transaction blocks can be preserved,
Petition 870190010582, of 01/31/2019, p. 11/30
16/43 using less computational capacity, which can also result in a more efficient addition of blocks to the Blockchain and, in turn, deny the use of additional nodes in the Blockchain network and reduce energy expenditure. In addition, the use of digital signatures may also allow participant devices 106 to validate transaction blocks, which would be impossible or impractical for devices of participants on traditional Blockchain networks due to computational demands.
Signatory Authority Server [0034] Figure 2 illustrates a modality of the signatory authority server 102 of system 100. Obviously, people skilled in the relevant technique will understand that the modality of the signatory authority 102 illustrated in figure 2 is provided only as an illustration and which may not be thorough in all possible server configurations of the signatory authority 102 suitable for the performance of the functions as discussed here. For example, the computer system 800 illustrated in figure 8 and discussed in more detail below can be an appropriate configuration of the signatory authority server 102.
[0035] The signatory authority server 102 may include a receiving device 202. Receiving device 202 may be configured to receive data over one or more networks via one or more network protocols. In some cases, the receiving device 202 may also be configured to receive data from member processing servers 104, participant devices 106 and other entities through suitable communication networks, such as local area networks, networks of wide area, radio frequency networks, the Internet. In some embodiments, the receiving device 202 may consist of multiple devices, such as different devices

17/43 receiving device to receive data through different networks, such as a first receiving device to receive data via near field communication and a second receiving device to receive data via the Internet. The receiving device 202 can receive electronically transmitted data signals, in which the data can be superimposed on the data signal, decoded, analyzed, read or otherwise obtained by receiving the data signal by the receiving device 202. In some In such cases, the receiving device 202 may include an analysis module for analyzing the received data signal to obtain the data superimposed on it. For example, the receiving device 202 may include an analysis program configured to receive and transform the received data signal into a usable register for the functions performed by the processing device to execute the methods and systems described here.
[0036] Receiving device 202 can be configured to receive data signals electronically transmitted by member processing servers 104. Data signals coming from member processing servers 104 can be superimposed on members' public keys for signing, transaction blocks and the signed hash values used for signing, as well as the results of the validations performed on the signed transaction blocks. The receiving device 202 can also be configured to receive data signals electronically transmitted by the devices of participants 106, which can be superimposed on the validation results. In some embodiments, the receiving device 202 can receive data signals from third parties, such as data signals received during the domain key signature

The communication module 204 can be composed of one or more types of communication and use several communication methods for communications within a computing device. For example, the communication module 204 can consist of a bus, contact pin connectors, wires, etc. In some embodiments, the communication module 204 can also be configured to communicate with the internal components of the signatory authority server 102 and the external components of the signatory authority server 102, such as externally connected databases, display devices, devices input, etc. The signatory authority server 102 may also include a processing device. The processing device can be configured to perform the functions of the signatory authority server 102 discussed here as will become apparent to persons skilled in the relevant technique. In some embodiments, the processing device may include and / or be composed of a plurality of mechanisms and / or modules specially configured to perform one or more functions of the processing device, such as a query module 206, a generation module 208 , a signature module 210, an authentication module 212, etc. As used here, the term module can be software or hardware particularly programmed to receive an input, execute one or more processes using the input and provide an output.

19/43 executed by several modules will become evident to a person skilled in the art based on the present invention.
[0038] The signatory authority's server 102 may include a query module 206. The query module 206 can be configured to perform queries against databases to identify information. Query module 206 can receive one or more data values or query strings and can execute a query string based on them in an indicated database, such as a memory 216, to identify information stored therein. The query module can then send the identified information to an appropriate mechanism or module on the signatory authority's server 102 when necessary.

[0052] The member processing server 104 can also include a 312 validation module. The 312 validation module can be configured to receive data for validation, can validate the data and can send a result (for example, success or failure) ) from validation to another member processing server module or engine 104. For example, validation module 312 can receive (for example, via receiving device 302) a signed block, which can be validated by the membership module validation 312 using a signed public domain key, associated with the signatory authority's 102 server that signed the block. The 312 validation module can also validate signed hash values (for example, which can be obtained by validating a signed block that includes the signed hash value) using the already signed members public key. The member public key can be the member public key generated by generation module 308, or it can be a member public key received from the signatory authority server 102 that is associated with the member processing server 104 used to sign the hash value. In the latter case, the signatory authority server 102 may provide (for example, with the signed block) the members' public key already signed or an indication that the member public key should be used for validation.

Petition 870190010582, of 01/31/2019, p. 44/111
30/43 key generation and can be composed of a private domain key and a corresponding public domain key. In step 404, the signing module 210 of the signatory authority server 102 can self-sign the public domain key. In some cases, the public domain key can be signed using the corresponding private domain key. In other cases, a different private key can be used. In some embodiments, step 404 can be replaced by signing the public domain key with a trusted third party.
[0058] In step 406, the generation module 308 of a member processing server 104 can generate a member key pair. The member key pair can be generated using a suitable key pair generation algorithm and can be composed of a member private key and a corresponding member public key. In step 408, the transmission device 314 of the member processing server can electronically transmit a data signal to the signatory authority's server 102 using a suitable communication network, in which the data signal is superimposed on the generated member public key and authentication data.

Once authentication is complete, in step 414, signature module 210 on the
Petition 870190010582, of 01/31/2019, p. 45/111
31/43 signatory authority 102 can sign the member public key using the private domain key.
[0060] In step 416, the transmitting device 214 of the signatory authority's server 102 can electronically transmit a data signal to the member processing server 104 using a suitable communication network that is superimposed on the already signed members public key, as well as additional already signed member public keys associated with other member processing servers 104. In some cases, the already signed public domain key can also be transmitted to member processing server 104. In step 418, the device receiver 302 from member processing server 104 can receive the data signal to analyze the data included therein.
Generation and Validation of Digitally Signed Blocks [0061] Figure 5 illustrates a process for the generation of a digitally signed block of Blockchain transactions and validation using the signatory authority server 102 and the member processing server 104 of system 100 illustrated in figure 1.
[0062] In step 502, the receiving device 302 of the member processing server 104 can receive a plurality of Blockchain transactions. Each Blockchain transaction can be received from a participant device 106 and can include the data associated with the transaction to be posted on the Blockchain associated with the member processing server 104. In step 504, the generation module 308 of the server processing member 104 can generate a new block composed of Blockchain transactions. In some cases, the block may also include additional data, such as a header, a transaction counter and other data. The additional data included in a block of the
Petition 870190010582, of 01/31/2019, p. 46/111
32/43
Blockchain may be dependent on the characteristics of the Blockchain, as will become evident to people versed in the relevant technique.
[0063] In step 506, the generation module 308 of the member processing server 104 can find a suitable hash value. The action of finding a suitable hash value may include generating a first hash value by applying a scatter algorithm to a block on the previous Blockchain, such as adding the block that precedes the new block, as well as generation or other identification of a second hash value that corresponds to the first hash value. Once the appropriate hash value is identified, in step 508, the signature module 310 of the member processing server 102 can sign the hash value using its private member key.
[0064] In step 510, the transmission device 314 of the member processing server 104 can electronically transmit a data signal to the signatory authority's server 102 using a suitable communication network that is superimposed on the new block and the hash value signed. In step 512, the receiving device 202 of the signatory authority's server 102 can receive the data signal to analyze the data overlaid on it. In step 514, the signing module 210 of the signatory authority's server 102 can sign the combined block, composed of the new block and the signed hash value, using its private domain key.
[0065] In step 516, the transmitting device 214 of the signatory authority's server 102 can electronically transmit a data signal superimposed on the digitally signed block to the member processing server 104 using the appropriate communication network. In step 518, the receiving device 302 from the server
Petition 870190010582, of 01/31/2019, p. 47/111
33/43 member processing 104 can receive the signed block and, in step 520, the validation module 312 of member processing server 104 can validate the signed block using the already signed public domain key and the members public key already signed. In some embodiments, steps 518 and 520 can be performed by a member processing server 104 other than the one used in steps 502 to 510. In such modalities, the validation performed in step 520 can use the already signed member public key, associated with the member processing server 104 used to sign the hash value in step 508.
First Exemplary Method of Using Digital Signatures to Sign Blockchain Transactions [0066] Figure 6 illustrates a 600 method for digitally signing a block of Blockchain transactions that includes a signed hash value to validate them.
[0067] In step 602, a pair of domain keys can be generated by a generation module (for example, the generation module 208) of a processing server (for example, the signatory authority server 102), in which the domain key pair comprises a private domain key and a public domain key, and where the public domain key is signed after its generation. In step 604, a plurality of member public keys can be received by a receiving device (for example, receiving device 202) from the processing server, where each member public key is received from an associated member ( for example, member processing server 104) of a Blockchain network and is a public key in a key pair comprising a member public key and a corresponding member private key
Petition 870190010582, of 01/31/2019, p. 48/111
34/43 to the associate member.
[0068] In step 606, each member public key of the plurality of member public keys can be signed by a signature module (for example, signature module 210) of the processing server using the private domain key. In step 608, a transaction block can be received by the processing server receiving device from a specific member of the Blockchain network, in which the transaction block includes a plurality of Blockchain transaction values and a signed hash function using the member private key corresponding to the specific member.
[0069] In step 610, the block of received transactions can be signed by the signature module of the processing server using the private domain key. In step 612, the signed transaction block can be electronically transmitted by a transmission device (for example, the transmission device 214) of the processing server.
[0070] In one embodiment, method 600 may also include transmitting electronically, through the transmission device of the processing server, each member public key already signed to one or more members of the Blockchain network. In some embodiments, the public domain key can be signed by a public authority. In other ways, the public domain key can be signed by the signature module of the processing server. In one embodiment, method 600 may also include: receiving, via the receiving device from the processing server, authentication information from each member of the Blockchain network; and authenticate, through an authentication module (for example, authentication module 212) of the processing server, each member of the Blockchain network using the

Second Exemplary Method of Using Digital Signatures to Sign Blockchain Transactions [0071] Figure 7 illustrates a method 700 for the digital signature of a hash value to be included in a Blockchain transaction block for digital signature and inclusion in the Blockchain.
[0072] In step 702, the Blockchain can be stored in a memory (for example, memory 316) of a processing server (for example, the member processing server 104), where the Blockchain includes a plurality of blocks transactions, each transaction block including at least a plurality of Blockchain transaction values. In step 704, a member key pair comprising a member private key and a member public key can be generated by a generation module (for example, the generation module 308) of the processing server.
[0073] In step 706, the generated member public key can be transmitted electronically by a transmission device (for example, the transmission device 314) from the processing server to a signatory authority (for example, the signatory authority's server 102 ) associated with a Blockchain network. In step 708, a plurality of Blockchain transaction values can be received by a receiving device (e.g., receiving device 302) from the processing server that comprises a new transaction block.
[0074] In step 710, a hash module (for example, the generation module 308) of the processing server can map a first hash value by applying one or more dispersion algorithms to a specific block of the plurality of
Petition 870190010582, of 01/31/2019, p. 50/111
36/43 transaction blocks included in the Blockchain. In step 712, a second hash value can be generated by the generation module of the processing server that corresponds to the first hash value.
[0075] In step 714, the second generated hash value can be signed by a signature module (for example, signature module 210) of the processing server using the member private key that was generated. In step 716, the new transaction block and the second signed hash value can be electronically transmitted by the transmitting device from the processing server to the signatory authority.
[0076] In one embodiment, the second hash value can be generated by applying one or more dispersion algorithms to the new transaction block that has been received. In some embodiments, method 700 may also include transmitting electronically, via the transmission device of the processing server, authentication information to the signatory authority. In one embodiment, method 700 may also include: receiving, via the receiving device from the processing server, a signed transaction block and the signed public domain key from the signatory authority, in which the signed transaction block includes the new transaction block and the second signed hash value and is signed using a private domain key corresponding to the public domain key already signed; and validating, via a validation module (for example, the 312 validation module) of the processing server, the transaction block signed using the member public key and the signed public domain key. In another modality, the validation of the signed transaction block may include: applying the public domain key already signed to the signed transaction block to generate the new transaction block and the
Petition 870190010582, of 01/31/2019, p. 51/111
37/43 second signed hash value; applying the member public key to the second signed hash value to generate the second hash value; and validating the second generated hash value as a match for the second generated hash value.
