METHOD AND SYSTEM FOR FAST TRACKING NAVIGATION OF BLOCKCHATNS VIA DATA MAND?ULATION

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of, and priority to, U.S. Patent Application No. 15/332,348 filed on October 24, 2016. The entire disclosure of the above application is incorporated herein by reference.

FIELD

The present disclosure relates to the fast tracking of navigation of a blockchain, specifically the generation of a blockchain configured for fast track navigation via the use of additional flags and hashed referenced values in block headers to achieve faster navigation and verification of a blockchain.

BACKGROUND

Blockchains provide for a decentralized and independently verifiable storage mechanism for data. While initially developed for use with financial transactions using a cryptographic currency, additional implementations for blockchains have been developed that take advantage of the decentralized nature of the blockchain as well as the ability for the blockchain to be both immutable and independently verifiable. One such additional implementation is the use for a blockchain to provide a legal record where documents can be stored that are verifiable and tied to a specific timestamp.

One of the benefits of the blockchain is it can serve as an immutable ledger that stores a record for every transaction ever conducted via that blockchain. As such, a blockchain may store thousands, millions, or even billions of transaction records over time in a vast number of different blocks. However, this may cause a difficulty for any new node that wants to participate in the blockchain. In such instances, a blockchain may contain thousands, millions, or billions of blocks, each of which must be verified by the new node prior to the generation and addition of new blocks to the blockchain. The verification of such a large number of blocks may take a significant amount of time, during which new blocks may be added to the blockchain, further delaying the ability for the new node to participate.

Thus, there is a need for a technical solution to increase the speed at which a blockchain may be navigated for verification thereof, which can thereby reduce the time required for a new node to begin participating in the blockchain.

SUMMARY

The present disclosure provides a description of systems and methods for the generation of a blockchain configured for fast navigation. The use of specialized flags and hash values included in the headers of blocks in a blockchain may enable for the speed of navigation of a blockchain to be significantly increased, which may greatly reduce the computing time and power required to verify the blockchain. As a result, navigation and verification of the blockchain may be more efficient, which may increase the ability for new nodes to participate in the blockchain, and for users and nodes to review the blockchain to identify specific transaction records.

A method for generating a blockchain configured for fast navigation includes: storing, in a memory of a processing server, a blockchain, wherein the blockchain is comprised of a plurality of blocks, where each block includes at least one or more transaction values and a header comprised of at least a fast track flag, fast track reference, a timestamp, and hash value, and where the plurality of block is comprised of a plurality of standard blocks having a deactivated fast track flag and one or more fast track blocks having an activated fast track flag; executing, by a querying module of the processing server, a first query on the blockchain to identify a most recent fast track block based on the timestamp included in the header of each of the one or more fast track blocks; executing, by the querying module of the processing server, a second query on the blockchain to identify a most recent overall block based on the timestamp included in the header of each of the plurality of blocks; generating, by a hashing module of the processing server, a fast track hash value via application of a first predefined hashing algorithm to the identified most recent fast track block; generating, by the hashing module of the processing server, a chain hash value via application of a second predefined hashing algorithm to the identified most recent overall block; and writing, by the querying module of the processing server, a new block to the blockchain, wherein the new block includes at least a block header comprised of a timestamp, an activated fast track flag, the fast track hash value, and the chain hash value.

A system for generating a blockchain configured for fast navigation includes: a memory of a processing server configured to store a blockchain, wherein the blockchain is comprised of a plurality of blocks, where each block includes at least one or more transaction values and a header comprised of at least a fast track flag, fast track reference, a timestamp, and hash value, and where the plurality of block is comprised of a plurality of standard blocks having a deactivated fast track flag and one or more fast track blocks having an activated fast track flag; a querying module of the processing server configured to execute a first query on the blockchain to identify a most recent fast track block based on the timestamp included in the header of each of the one or more fast track blocks, and a second query on the blockchain to identify a most recent overall block based on the timestamp included in the header of each of the plurality of blocks; and a hashing module of the processing server configured to generate a fast track hash value via application of a first predefined hashing algorithm to the identified most recent fast track block, and a chain hash value via application of a second predefined hashing algorithm to the identified most recent overall block. The querying module of the processing server is further configured to write a new block to the blockchain, wherein the new block includes at least a block header comprised of a timestamp, an activated fast track flag, the fast track hash value, and the chain hash value.

DETAILED DESCRIPTION

Glossary of Terms

Blockchain - A public ledger of all transactions of a blockchain-based currency. One or more computing devices may comprise a blockchain network, which may be configured to process and record transactions as part of a block in the blockchain. Once a block is completed, the block is added to the blockchain and the transaction record thereby updated. In many instances, the blockchain may be a ledger of transactions in chronological order, or may be presented in any other order that may be suitable for use by the blockchain network. In some configurations, transactions recorded in the blockchain may include a destination address and a currency amount, such that the blockchain records how much currency is attributable to a specific address. In some instances, the transactions are financial and others not financial, or might include additional or different information, such as a source address, timestamp, etc. In some embodiments, a blockchain may also or

alternatively include nearly any type of data as a form of transaction that is or needs to be placed in a permissionless, distributed database that maintains a continuously growing list of data records hardened against tampering and revision, even by its operators, and may be confirmed and validated by the blockchain network through proof of work and/or any other suitable verification techniques associated therewith. In some cases, data regarding a given transaction may further include additional data that is not directly part of the transaction appended to transaction data. In some instances, the inclusion of such data in a blockchain may constitute a transaction. In such instances, a blockchain may not be directly associated with a specific digital, virtual, fiat, or other type of currency. In some cases, participation in a blockchain (e.g., as a node submitting and/or confirming transactions) may be permissionless (e.g., not moderated or restricted). In other cases, a blockchain may be a

permissioned blockchain where only authorized computing devices may operate as nodes, where a level of participation may be based on permissions associated therewith.

System for Fast Tracking of Blockchain Navigation

FIG. 1 illustrates a system 100 for the generation of a blockchain that is configured for fast track navigation to facilitate quicker navigation as well as verification of blocks in the blockchain.

The system 100 may include a processing server 102. The processing server 102, discussed in more detail below, may be configured to generate a blockchain that is configured for fast track navigation, which may include specialized fast track blocks used in the fast track navigation of the blockchain. The processing server 102 may be one of a plurality of nodes associated with the blockchain, each of which may be configured to receive transaction records for inclusion in blocks that are generated for addition to the blockchain. For instance, the system 100 illustrated in FIG. 1 includes four computing devices 106, illustrated as computing devices 106a, 106b, 106c, and 106d, where each of the computing devices 106 may be an additional node in the blockchain network associated with the blockchain. In some cases, each of the computing devices 106 may be performed to perform the same functions as the processing server 102 as discussed herein. In other cases, the computing devices 106 may be configured to generate and add standard blocks to the blockchain, but may not be configured to generate and add fast track blocks to the blockchain.

In some embodiments, the blockchain may be a permissioned blockchain that may utilize digital signatures. Additional information regarding permissioned blockchains that utilize digital signatures for blocks is discussed in U.S. Patent Application No. 14/976,331, entitled "Method and System Blockchain Variant Using Digital Signatures," filed December 21, 2015, by David J. King, which is herein incorporated by reference in its entirety. In such embodiments, a domain authority may be required to digitally sign any fast track block prior to addition to the blockchain. In some such embodiments, the processing server 102 may be a domain authority. In other such embodiments, the processing server 102 may generate fast

track blocks using the methods discussed herein, which may be digitally signed by the processing server 102, but provided to a domain authority for verification and further signing before addition to the blockchain.

The processing server 102 may be configured to generate fast track blocks for addition to the blockchain. Fast track blocks may include at least a block header. In some embodiments, a fast track block, in contrast to standard blocks in the blockchain, may not include any transaction values or may include a null value in place of transaction values. In other embodiments, a fast track block may include a plurality of transaction values, and may thus perform the functions of a standard block in addition to being a fast track block used for fast track navigation.

The block header included in each block in the blockchain may include at least a timestamp, a hash value, a fast track flag, and a fast track reference. The timestamp may be a timestamp that is generated when the block header is generated for inclusion in the new block to be added to the blockchain. The timestamp may be represented using any suitable type of representation, such as a DateTime value, a time in seconds since the beginning of the UNIX epoch, etc.

The hash value may be a value that is generated via hashing of the most recent block added to the blockchain. The processing server 102 may identify the block most recently added to the blockchain based on the timestamps included in the respective block header for each of the blocks in the blockchain. The processing server 102 may then apply one or more predetermined hashing algorithms to the block to generate the hash value. The hash value may then be included in the block header for the new block that will be added to the blockchain. The use of such hash values may ensure immutability of the blockchain, as any changes to the a block would result in a different hash value being generated, which would invalidate the hash value in the next block. Furthermore, if the hash value is to be changed in that next block to accommodate, it would thus change the hash value generated from that next block, thus propagating the invalidation through the entire remainder of the blockchain.

The fast track flag may be a flag that indicates if the block is a fast track block or a standard block. The fast track flag may use any type of value to indicate an activated or deactivated status for the respective block. For instance, in one example, the fast track flag may be a single bit where a "1" value indicates activation (e.g., that the block is a fast track block) and where a "0" value indicates deactivation (e.g., that the block is not a fast track block). In another example, the fast track flag may be a Boolean where a "TRUE" value indicates activation. The fast track flag in each standard block, or each block that is not a fast track block in instances where there may be multiple block types, may be deactivated.

The fast track reference may be a hash value of the most recent fast track block in the blockchain. The most recent fast track block may be identified by the timestamp included in the block header, where the timestamp is the most recent one among all blocks that have an activated fast track flag. The processing server 102 may generate the fast track reference via applying one or more predetermined hashing algorithms to the most recent fast track block. In some embodiments, the same hashing algorithm(s) used to generate the hash value of the most recent overall block may also be used to generate the fast track reference. In other embodiments, a different algorithm or algorithms may be used.

The fast track reference and an activated fast track flag may both be included in the block header for fast track blocks to facilitate the fast navigation of the blockchain. A node in the blockchain network, or any computing device verifying the blockchain or data included therein, may quickly navigate the blockchain by identifying blocks that have activated fast track flags. For verification, the node may identify the earlier fast track block (e.g., based on timestamp) and hash that block using the predetermined hashing algorithm(s), and then verify that the fast track reference in the more recent fast track block is the same as the hash of the earlier fast track block.

In some embodiments, the processing server 102 may be configured to digitally sign a fast track block prior to addition to the blockchain. In such embodiments, the processing server 102 may store a cryptographic key pair that includes a private key and a corresponding public key. The processing server 102 may digitally sign generated fast track blocks using the private key, which may be verified using the corresponding public key, such as may be provided to nodes in the blockchain network (e.g., computing devices 106). In some cases, the processing server 102 may be configured to generate the key pair used to digitally sign blocks using a suitable encryption algorithm.

In instances where a fast track block may include one or more transaction values, the block header for the respective block may further include a Merkle root. The Merkle root may be the root of a Merkle tree that is generated using the transaction values that are to be included in the block. In some cases, the

processing server 102 may order the transaction values prior to generation of the Merkle tree. The Merkle tree may be generated using one or more hashing algorithms, which, in some instances, may be the same hashing algorithm(s) used to generate the hash value of the most recent block and/or the fast track reference value included in the block header. In cases where a fast track block may not include any transaction values, the block header may still include a Merkle root, such as of a Merkle tree generated using a null or other predetermined value, or may include a null or predetermined value in place of the Merkle root.

The methods and systems discussed herein may enable the generation of a blockchain that is configured for fast navigation through the use of specialized fast track flags and fast track reference values. Such data may enable not only faster navigation of a blockchain, but also faster verification of the blocks included in the blockchain to provide for more efficient computing related thereto. As a result, new computing devices 106 may participate as nodes in the associated blockchain network more quickly than in blockchain networks that use traditional blockchains.

Processing Server

FIG. 2 illustrates an embodiment of a processing server 102 in the system 100. It will be apparent to persons having skill in the relevant art that the embodiment of the processing server 102 illustrated in FIG. 2 is provided as illustration only and may not be exhaustive to all possible configurations of the processing system 102 suitable for performing the functions as discussed herein. For example, the computer system 500 illustrated in FIG. 5 and discussed in more detail below may be a suitable configuration of the processing server 102.

The processing server 102 may include a receiving device 202. The receiving device 202 may be configured to receive data over one or more networks via one or more network protocols. The receiving device 202 may be configured to receive data from computing devices 104 and other devices and systems via suitable communication networks and corresponding network protocols. In some

embodiments, the receiving device 202 may be comprised of multiple devices, such as different receiving devices for receiving data over different networks, such as a first receiving device for receiving data over a local area network and a second receiving device for receiving data via a blockchain network. The receiving device 202 may receive electronically transmitted data signals, where data may be superimposed or otherwise encoded on the data signal and decoded, parsed, read, or otherwise obtained via receipt of the data signal by the receiving device 202. In some instances, the receiving device 202 may include a parsing module for parsing the received data signal to obtain the data superimposed thereon. For example, the receiving device 202 may include a parser program configured to receive and transform the received data signal into usable input for the functions performed by the processing device to carry out the methods and systems described herein.

The receiving device 202 may be configured to receive data signals electronically transmitted by computing devices 106, which may be superimposed or otherwise encoded with data associated with the blockchain network, such as transactions or new blocks for addition to the blockchain. The receiving device 202 may also be configured to receive data signals electronically transmitted by computing devices 106 or other nodes in the blockchain network, or by input devices interfaced with the processing server 102, that are superimposed or otherwise encoded with requests for fast track blocks. For example, a computing device 106 as a node in the blockchain network or an operator of the processing server 102 may submit a request for a new fast track block to be added to the blockchain. In some instances, such requests may be received periodically, such as a request for a new fast track block to be added after a predetermined period of time or after a predetermined number of standard blocks have been added since the last fast track block.

The processing server 102 may also include a communication module 204. The communication module 204 may be configured to transmit data between modules, engines, databases, memories, and other components of the processing server 102 for use in performing the functions discussed herein. The communication module 204 may be comprised of one or more communication types and utilize various communication methods for communications within a computing device. For example, the communication module 204 may be comprised of a bus, contact pin connectors, wires, etc. In some embodiments, the communication module 204 may also be configured to communicate between internal components of the processing server 102 and external components of the processing server 102, such as externally connected databases, display devices, input devices, etc. The processing server 102 may also include a processing device. The processing device may be configured to perform the functions of the processing server 102 discussed herein as will be apparent to persons having skill in the relevant art. In some embodiments, the

processing device may include and/or be comprised of a plurality of engines and/or modules specially configured to perform one or more functions of the processing device, such as a querying module 210, hashing module 212, generation module 214, signing module 218, etc. As used herein, the term "module" may be software or hardware particularly programmed to receive an input, perform one or more processes using the input, and provide an output. The input, output, and processes performed by various modules will be apparent to one skilled in the art based upon the present disclosure.

The processing server 102 may include a querying module 210. The querying module 210 may be configured to execute queries on databases to identify information. The querying module 210 may receive one or more data values or query strings, and may execute a query string based thereon on an indicated database to identify information stored therein. The querying module 210 may then output the identified information to an appropriate engine or module of the processing server 102 as necessary. The querying module 210 may, for example, execute a query on a memory 220 of the processing server 102 to identify specific blocks in the blockchain, such as to identify the most recent overall block in a blockchain and the most recent fast track block in a blockchain for use in the generation of a new fast track block to be added.

The processing server 102 may also include a hashing module 212.

The hashing module 212 may be configured to generate hash values via the application of one or more hashing algorithms to data supplied to the hashing module 212. The hashing module 212 may receive data to be hashed as input, may apply one or more hashing algorithms to the data, and may output the generated hash value to another module or engine of the processing server 102. In some cases, the hashing module 212 may be supplied with the hashing algorithm(s) to be used in generation a hash value. In other cases, the hashing module 212 may identify the hashing algorithm(s) to be used, such as via the generation of queries for execution by the querying module 210 on the memory 220. The hashing module 212 may be configured, for example, to generate hash values of block headers to be used as a reference to a prior block, including block headers for overall recent blocks as well as recent fast track blocks, and to generate merkle roots of transaction values for inclusion in a block header of a block.

The processing server 102 may also include a generation module 214. The generation module 214 may be configured to generate new block headers and new blocks for use in performing the functions of the processing server 102 as discussed herein. The generation module 214 may receive a request, may generate data based on that request, and may output the generated data to another module or engine of the processing server 102. For example, the generation module 212 may be instructed to generate a fast track block for inclusion in the blockchain. The generation module 212 may generate the block header for the new fast track block and generate the new block itself for writing to the blockchain for the fast track thereof. The generation module 212 may also be configured to generate blocks and/or data included therein based on formatting rules, such as may be stored in the memory 220 of the processing server 102, included in a request for fast tracking, etc. The generation module 212 may also be configured to generate a cryptographic key pair, including a private key and corresponding public key, such as may be used in the digital signing of standard and/or fast track blocks.

The processing server 102 may also include a transmitting device 216. The transmitting device 216 may be configured to transmit data over one or more networks via one or more network protocols. The transmitting device 216 may be configured to transmit data to computing devices 106 and other entities via suitable communication networks and corresponding network protocols. In some

embodiments, the transmitting device 216 may be comprised of multiple devices, such as different transmitting devices for transmitting data over different networks, such as a first transmitting device for transmitting data over a local area network and a second transmitting device for transmitting data via a blockchain network. The transmitting device 216 may electronically transmit data signals that have data superimposed that may be parsed by a receiving computing device. In some instances, the transmitting device 216 may include one or more modules for superimposing, encoding, or otherwise formatting data into data signals suitable for transmission.

The transmitting device 216 may be configured to electronically transmit data signals to computing devices 106 and other nodes in the blockchain network that are superimposed or otherwise encoded with fast track blocks and standard blocks for addition to a blockchain for fast track navigation thereof. In some instances, the transmitting device 216 may also be configured to electronically

transmit data signals superimposed or otherwise encoded with a public key used for verification of digital signatures generated by the processing server 102. The transmitting device 216 may also be configured to electronically transmit data signals superimposed or otherwise encoded with the full blockchain, including both standard and fast track blocks, for fast track navigation and verification thereof.

In some embodiments, the processing server 102 may also include a signing module 218. The signing module 218 may receive data to be signed as input, may digitally sign the data, and may output the signed data to another module or engine of the processing server 102. In some instances, the signing module 218 may digitally sign data using a private key associated with the processing server 102. In such instances, the signing module 218 may receive the private key as input, or may identify the private key, such as by instructing the query module 210 to identify the private key in the memory 220 of the processing server 102. The signing module 218 may be configured to digitally sign terminal blocks and starting blocks generated by the generation module 214 of the processing server 102 prior to being written to the blockchain. In some embodiments, the signing module 218 may also be configured to verify digital signatures of blocks or other data for inclusion in the blockchain, such as those may be generated by computing devices 106 or other nodes in the blockchain network, using public keys associated with the respective node.

The processing server 102 may also include a memory 220. The memory 220 may be configured to store data for use by the processing server 102 in performing the functions discussed herein, such as a private key, key pair, formatting rules, a blockchain, etc. The memory 220 may be configured to store data using suitable data formatting methods and schema and may be any suitable type of memory, such as read-only memory, random access memory, etc. The memory 220 may include, for example, encryption keys and algorithms, communication protocols and standards, data formatting standards and protocols, program code for modules and application programs of the processing device, and other data that may be suitable for use by the processing server 102 in the performance of the functions disclosed herein as will be apparent to persons having skill in the relevant art. In some embodiments, the memory 220 may be comprised of or may otherwise include a relational database that utilizes structured query language for the storage, identification, modifying, updating, accessing, etc. of structured data sets stored therein.

Fast Track Navigation of a Blockchain

FIG. 3 illustrates a blockchain used in conjunction with the system 100 that is configured for fast track navigation via the use of multiple fast track blocks in addition to standard blocks that comprise the blockchain.

As illustrated in FIG. 3, a blockchain 302 may be comprised of a plurality of different blocks, including a plurality of fast track blocks 304 and standard blocks 306. As illustrated, the fast track blocks 304 may be spread out such that there is a plurality of standard blocks 306 between each fast track block 304. In some embodiments, there may be a predetermined number of standard blocks 306 between fast track blocks 304. In other embodiments, a predetermined period of time may pass between the addition of a new fast track block 304 to the blockchain 302, where standard blocks 306 may continue to be added.

Each block in the blockchain 302, including both fast track blocks 304 and standard blocks 306, may include a block header 308 and one or more transaction values 310. The transaction values 310 may include transaction records or other data associated with transactions that are conducted using the blockchain 302. In some instances, fast track blocks 304 may include a null value in the transaction values 310 in place of transaction records, such as in instances where fast track blocks 304 may not be used to record transaction in the blockchain 302, such as to serve purely for navigation and verification of the blockchain 302.

Each block header 308, including block headers 308 in both fast track blocks 304 and standard blocks 306, may include at least a fast track flag 312. As illustrated in FIG. 3, the fast track flag 312 may be activated in each of the fast track blocks 304 and deactivated in each of the standard blocks 306, as illustrated by the shading of the fast track flag 312. Each of the block headers 308 may also include a fast track reference 314, block reference 316, and a timestamp 318.

As illustrated in FIG. 3, the fast track reference 314 may be based on the previous fast track block 304 that is in the blockchain 302. The fast track reference 314 may be a hash value generated via application of one or more hashing algorithms (e.g., via the hashing module 212 of the processing server 102) to the previous fast track block 304. In instances where the fast track block 304 being added may be the very first fast track block 304 in the blockchain 302, then the fast track reference 314 may be a hash of the very first block in the blockchain 302, which, in such an instance, may be a standard block 306. In some cases, the very first block in the blockchain 302, such as illustrated in FIG. 3, may be a fast track block 304. In such a case, the fast track reference 314 may be a null value or the hashing of a null value.

The block reference 316 may be based on the previous block in the blockchain 302, as determined based on the respective timestamps 318. The block reference 316 may be a hash value generated via application of one or more hashing algorithms (e.g., via the hashing module 212 of the processing server 102) to the previous block, where the previous block may be a fast track block 304 or a standard block 306. In some instances, the same hashing algorithm(s) used to generate the fast track reference 314 may be used for the block reference 316. In cases where the block being added is the first block in the blockchain 302, the block reference 316 may be a null value or a hash of a null value, which may indicate the block as being the start to the blockchain 302.

The timestamp 308 may be a stamp of the time when the respective block header 308 is generated for addition to the blockchain 302. The timestamp 308 may be represented using any suitable format. In some cases, a block header 308 may include additional data, such as to accommodate further configurations and data for the blockchain 302. For instance, block headers 308 in the blockchain 302 may also include a Merkle root, generated using the transaction values 310 in the respective block. In some embodiments, a block may be digitally signed by the processing server 102 after generation, and prior to addition to the blockchain 302, such as via the signing module 218 of the processing server 102 using a private key associated therewith.

Exemplary Method for Generating a Blockchain Configured for Fast Navigation

FIG. 4 illustrates a method 400 for the generation of a blockchain that is configured for fast track navigation via the use of specially configured flags and reference values in block headers.

In step 402, a blockchain (e.g., blockchain 302) may be stored in a memory (e.g., the memory 220) of a processing server (e.g., the processing server 102), wherein the blockchain is comprised of a plurality of blocks, where each block includes at least one or more transaction values (e.g., transaction values 310) and a header (e.g., block header 308) comprised of at least a fast track flag (e.g., fast track flag 312), fast track reference (e.g., fast track reference 314), a timestamp (e.g., timestamp 318), and hash value (e.g., block reference 316), and where the plurality of blocks is comprised of a plurality of standard blocks (e.g., standard blocks 306) having a deactivated fast track flag and one or more fast track blocks (e.g., fast track blocks 304) having an activated fast track flag. In step 404, a first query may be executed on the blockchain by a querying module (e.g., the querying module 210) of the processing server to identify a most recent fast track block based on the timestamp included in the header of each of the one or more fast track blocks.

In step 406, a second query may be executed on the blockchain by the querying module of the processing server to identify a most recent overall block based on the timestamp included in the header of each of the plurality of blocks. In step 408, a fast track hash value may be generated by a hashing module (e.g., the hashing module 212) of the processing server via application of a first predefined hashing algorithm to the identified most recent fast track block.

In step 410, a chain hash value may be generated by the hashing module of the processing server via application of a second predefined hashing algorithm to the identified most recent overall block. In step 412, a new block may be written to the blockchain by the querying module of the processing server, wherein the new block includes at least a block header comprised of a timestamp, an activated fast track flag, the fast track hash value, and the chain hash value.

In one embodiment, the first predefined hashing algorithm and the second predefined hashing algorithm may be the same algorithm. In some embodiments, the most recent overall block may be a standard block. In one embodiment, the fast track reference included in the header of each of the plurality of standard blocks may be a null value. In some embodiments, the method 400 may further include electronically transmitting, by a transmitting device (e.g., the transmitting device 216) of the processing server, the blockchain including the new block to a plurality of computing devices (e.g., computing devices 106) associated with the blockchain.
