Aspects of the disclosure are drawn to payment processing using cache consensus methods with Argon2d cryptographic hashing security integration.
Organizations and users communicate with one another in different ways using payment processing methods and platforms that are both centralized and decentralized. Payment processing security is fundamental and an important concern is to secure and protect the data and the users or organizations that offer services to the customers. For payment processing methods to be effective and efficient data needs to be encrypted before being sent or received.
Blockchain is perceived as a secure and agnostic feature that integrates with decentralization and distributed computation. When using a blockchain wallet the payment responsibility lies with the user if the digital assets, payments, or token is lost or stolen. Once lost or stolen those digital assets may not be recoverable.
Recent technology achievements in blockchain or other decentralized payments which are based on PoW (Proof or Work), PoS (Proof of Stake), and PoH (Proof of History) consensus through the network hash rates can be very unstable and time consuming. These consensus systems are also vulnerable to side-channel attacks if they are using SHA-256 or SCRIPT cryptograph.
Transactions that involve blockchain using PoW can be slow, time consuming, and vulnerable to attacks. In certain cases, transactions have suffered attacks resulting in networks waiting days or weeks for the next block to be solved or reaching a consensus for a transaction to be completed on time or near real time.
Recent statistics show that hackers stole $600 million in cryptocurrencies due to the slow consensus and cryptography that was used to protect the transactions plus additional transaction fees and concentrations on large mining pools exposing the users to vulnerabilities on public blockchain.
The aforementioned prior art solutions include various drawbacks and shortcomings leaving much room for improvement.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosure. The summary is not an extensive overview of the disclosure. It is neither intended to identify key or critical elements of the disclosure nor to delineate the scope of the disclosure. The following summary merely presents some concepts of the disclosure in a simplified form as a prelude to the description below.
Aspects of the disclosure relate to systems and apparatuses for improving speed of transaction processing using a proof of cache system. The proof of cache system may be used to validate transactions using cached keys stored on Directed Acyclic Graph (DAG) nodes that are available. The cached keys may be encrypted using Argon2d cryptographic hashing.
In accordance with one or more embodiment, a payment processing validation system is provided which includes a key generator, at least one directed acyclic graph node, and a master node. The key generator generates a unique key for identifiers not found in cache memory and provides the unique key to the at least one directed acyclic graph node. The master node is in communication with the at least one directed acyclic graph node and validates the transaction if a consensus percentage between the master node and the at least one directed acyclic graph totals a predetermined threshold.

Proof of cache system 300 provides a validation pool that may include numerous nodes. In an embodiment, the nodes within a validation pool that have two-thirds or more keys stored in cache are selected from a candidate pool of keys that are already hosted or stored on the cache of majority nodes.
The validation may be selected through a proof of cache method using present keys to validate a transaction. In an embodiment, the initial keys generated may comprise two-thirds of the total number of keys already in cache. One skilled in the art will realize that different percentages of the total number of keys in cache other than two-thirds may be utilized in various embodiments of the disclosure.
Once a new transaction arrives onto a node it may immediately access key generator module control 304, as the transactions may include static and dynamic addresses from a payee or receiver. In an embodiment, key generator module control 304 may create a unique key and binds it to the static and dynamic key 306. Next, the transaction may be passed onto nodes (i.e. Node D 308) which are configured to store a copy of the unique key 310. A consensus may be determined by the shortest path to obtaining a two-thirds majority of the nodes.
In an aspect of the disclosure, the next time the same transaction is initiated, it may be processed through the key generator module control 304 which checks if the address is new or already known. If the address is already known (same as past transaction), the transaction may be tagged with the same unique key that has already been stored in the nodes cache. The pending transaction may be approved by any of the random nodes that have two-thirds majority.
Based on available computation resources, nodes AA1 (402) through AA10 (420) may be coupled together using a network arrangement that integrates the nodes for: 1) allocation, 2) execution of computational tasks used during payments and processing; 3) validation, and 4) storage of keys in cache memory used for validation once a new transaction is initiated. In an embodiment, the storage may also comprise a block chain ledger.
In another aspect of the disclosure, the allocation cross pairing may be a DAG. In an embodiment, node blocks may be either directly or indirectly related.
Payment processing proof of cache system 400 may be configured to distribute the computation sessions or tasks to the nodes according to the DAG. The nodes may be encoded to track and verify each transaction by validating and approving any new transaction by using a master node 422. The master node 422 may identify a majority of the nodes that have cached keys.
In yet another aspect of the disclosure, relationships are maintained and synchronized in real time. If it is determined that a received key is contained in the cache of any of the DAG nodes then that transaction is passed to that DAG node for validation. The pending transaction may be approved by a selection of nodes that have a two-thirds majority. One skilled in the art will realize that different percentages of the total number of keys in cache other than two-thirds may be utilized in various embodiments of the disclosure. In addition, the total consensus percentage of all of the DAG nodes and master node in the system totals to one hundred percent.
If a new transaction does not meet two-thirds of the nodes for consensus, a new unique key is generated and added to the other cached keys. In an embodiment, the new transaction may be passed onto the nodes for validation by using the shortest path. In future transaction processing, the same transactions by known identifiers may be executed faster and quicker using the proof of cache system 400.
In an aspect of the disclosure, a blockchain ledger is structured to record the execution of the computation tasks associated with the transactions. The blockchain ledger may also be structured to record all events and payments processing status and system resources.
In an embodiment, after a transaction is initiated it must be completed and cannot be cancelled because it follows the DAG requirements for validation and processing.
In another aspect of the disclosure, payment processing proof of cache system 400 includes Argon2d cryptography to prevent GPU cracking attacks. Argon2d provides a stable security feature to the payment processing proof of cache system 400. It may access the memory array in a data dependent order, which reduces the possibility of any attacks during the data transmission and consensus and hence protects the payment for P2P or any other transactions being initiated. Also, cryptography may be optimized to execute on a randomly selected timeframe to improve performance.
The payment processing proof of cache system 400 provides a sufficient degree of randomness regarding the selection of validation nodes and ultimately improves speed of payment consensus and payment processing.
Aspects of the embodiments have been described in terms of illustrative embodiments thereof. Numerous other embodiments, modifications and variations within the scope and spirit of the appended claims will occur to persons of ordinary skill in the art from a review of this disclosure. For example, one of ordinary skill in the art will appreciate that the steps illustrated in the illustrative figures may be performed in other than the recited order, and that one or more steps illustrated may be optional in accordance with aspects of the embodiments.
