Home Pages BlockGrid™



Aus-consult is the Inventor of BlockGrid™ technology for smart ledger application using policy based one-time key OTK™ per transaction. The system does not use public or private keys, instead generates random keys encoded and attached to the messages, where the receiving party decodes the key and decrypt the message for each transaction. The keys are discarded after one use and never used again.

Each request will generate and encode its own key, and the response will be a different key again created randomly. All transactions are pinned inside Grids with special Algorithm invented by the founder. All transactions are time stamped and are pinned to the grid and distributed to varied partner computers for reference.

How BlockGrid Technology is different from existing BlockChain?

Unlike Blockchain, BlockGrid™ is a new technology based on digital grids or DigitalGrids that includes the information on the transactions including but not limited to time stamp, A and B parties (Sender and Recipient), amount of transactions, DigiGrid™ position with the grid, hash information of previous DigiGrid™ and a secret number which is created from the clever Algorithm. The secret number is then hashed along all the other transaction information for inclusion into the next transaction. This secret number is recreated when verification of transaction is required which will validate each DigiGrid™ or each transaction.

Once a Grid is full and all transactions are validated, then the Grid itself is validated by all involved decentralized computers, using the same Algorithm. After the validation of a full Grid, the Grid becomes the Block hence the creation of the BlockGrid. Each full Grid or now called Block is then distributed, validated and final Hash information is extracted from the final transaction to be included in the next Grid.

Advantage of BlockGrid:

  1. It is faster for mining and validating blocks, and easier to validate each transaction.  

  2. It provides additional security for the transaction, as each DigiGrid is positioned in respect to other 3 or 4 DigiGrids. The position of each DigiGrid and associated transaction is determined by the Algorithm not by going left to right or right to left within the two-dimensional grid. It is this two-dimensional mathematical Algorithm which differentiates it from one-dimensional Blockchain.

  3. It can easily be verified by the sender or recipient by clicking on associated relevant DigiGrid as shown, while other Transactions are not allowed to be seen, unless requested legally.

  4. As there will be no keys to worry between clients and super-servers. The Keys that are used between the super-servers are Real Random Keys and not Pseudo-Random keys and the Random Keys are only used once and then discarded, hence no chance for tempering.


For the grid size of 5 by 5 the transactions are distributed below. Any transaction which belongs to a particular sender can be seen by clicking associated DigiGrid which is shown as Green. The rest is shown is yellow indicating other people’s transactions. In the example below the number 3 is shown to be the sender’s transaction and by clicking this DigiGrid, the following would transaction appears:

Example only:

Here is your Grid

{‘previous_hash’: ‘c204f7c6092a8343d78a0673715af51396f2d86056279c78ebf90911b2970195’, ‘TX’: 1, ‘transaction’: [{‘sender’: ‘AC’, ‘recipient’: ‘DAVIDO SMITHO’, ‘amount’: 110.33, ‘date’: ’10/16/19′, ‘time’: ’11:11:15′}, {‘sender’: ‘AC’, ‘recipient’: ‘Georgo Creno’, ‘amount’: 225.24, ‘date’: ’10/16/19′, ‘time’: ’11:11:53′}, {‘sender’: ‘AC’, ‘recipient’: ‘PETRO LEOGO’, ‘amount’: 44444.0, ‘date’: ’10/16/19′, ‘time’: ’11:12:15′}, {‘sender’: ‘MINING’, ‘recipient’: ‘AC’, ‘amount’: 1.5}], ‘PN’: 690, ‘date’: ’10/16/19′, ‘time’: ’11:12:37′}



In 1995, in Sydney Area Section Telstra, a team of Engineers and Technical officers were producing design packs for several projects relevant to switching and transmission designs to be inputted to project managers for implementing the design packs in different telephone exchanges. There was a pressure from project managers that they need the designs to be ready as soon possible as to meet the required construction deadlines. Telstra allowed the engineers and technicians to work overtime to meet the requirements.

There was a problem that most designers sought approval for overtime not less than 3 hours per day. Unfortunately, some worked one hour, and some did not work at all, and they all claimed full payment, with no improvement in productivity.

The sectional supervisor (Ghulam Reza Rezaie), solved this problem by creating Digital Grids using C programming language, where each designer clicking on an Icon seeking approval (the program counted available hours against number of design packs to be completed, hence approval for overtime was given automatically, if normal hours were not enough to the complete the work), and clicking on Start-Icon to start work then after completion of the work clicking on the Finish-Icon. The transactions with relevant information such as hours approved, time started, time finished and hours worked were recorded on the Grid and a copy of receipt is sent to the designer, a copy to the supervisor and a copy for the payment officer for payment. At that time, it was not called BlockGrid, it was simply referred to as overtime digital grid.

The system was implemented in Sydney Area Section and resulted in 35% saving on overtime and productivity. However, due to the objections from the union, it was not offered to other sections.

With the advent of the Blockchain and its popularity the Supervisor wrote the same codes in Python language and hence created the BlockGrid system for use.

The system will be available for further development for any company that wants to apply the BlockGrid into their applications.
