1 Architectural aspects of the Arkreen Network within the Arweave ecosystem

The Arkreen Network employs a sophisticated approach to monitor its green energy production through the utilization of our advanced Proof of Green Energy Generation (PoGG) algorithm. Miners engaged in completing PoGG tasks are eligible to receive incentives for their efforts. This innovative PoGG algorithm plays a pivotal role in gauging the Arkreen Network’s green energy generation capabilities, forming the bedrock upon which the network delivers a range of services associated with green energy data assets.

To ensure accuracy and reliability, the Arkreen network has established a protocol for compensating miners who consistently provide precise data regarding green electricity production. All miners connected to the Arkreen network are mandated to sample data at regular intervals, specifically every five minutes (5 mins), and store this data locally. Subsequently, they are required to submit the cached data on an hourly basis (1 hr). Following the data report, miners have the option to erase the local cache data, preparing themselves for the upcoming data submission cycle. This meticulous process ensures the Arkreen Network maintains a robust and dependable record of its green energy production, further solidifying its commitment to sustainable energy practices.

Below, we describe the high-level architecture of the Arkreen Network to collect, convert, and store valuable PoGG data in an Arweave decentralized Permanent storage system.

2 Notary Contract Architecture of the ArKreen Network

The Arkreen Network archives the raw data generated by Arkreen miners within the decentralized Arweave storage system while recording the transaction IDs of uploads in the Arkreen Notary contract deployed on the Polygon blockchain.

Arkreen Network uses a hierarchy data structure to store green data in the Arweave storage system. The root of the data structure is the root transaction ID, which is a file that includes a lot of daily transaction IDs. The daily transaction ID is a JSON file that includes the daily data files of all the Arkreen miners.

Each day, Arkreen Network packs all daily data generated two days ago in a JSON file. The file includes a JavaScript object, which has many fields. The field name is the miner address, and the value is the daily green data of a single miner. The JSON file will be uploaded to Arweave storage and generate a single transaction ID; this is the daily transaction ID.

The latest generated daily transaction ID and all the old daily transaction IDs will be packed into a single file and also uploaded to Arweave; this is the root transaction ID, and then the root transaction ID will be notarized in the Arkreen Notary contract on the Polygon blockchain. Anyone can use the root transaction ID in the Arkreen Notary contract to fetch all data generated by the Arkreen Network to check or utilize this data.

3 How does Arkreen Network create daily Transaction ID (Tx ID) using the Arweave permanent storage system?

Figure 2: Miner Daily Generated Transaction IDs (TxIds) for the Arkreen Network on Arweave

The term “tx-day” in the context of the Arkreen network signifies a specific file format, which takes the form of a JSON string. This JSON string, functioning as a structured JavaScript object, comprises an array of distinct fields. Notably, each field within this object is uniquely identified by a miner’s address, serving as its field name.

In tandem with these field names, there exists a corresponding JavaScript array. These arrays serve as containers for a collection of PoGG reports, each exclusively generated by the miner associated with the corresponding address. To delve deeper into the nature of these PoGG reports, they encapsulate vital green energy data generation. Each element within the JavaScript array represents an individual PoGG report, meticulously documenting the miner’s commitment to green practices and sustainable energy consumption, supply, and storage in an Arweave permanent storage system. This highly organized data structure not only streamlines the tracking process but also facilitates the retrieval of comprehensive information pertaining to the ecological impact of every miner within the Arkreen network. In essence, it allows for a detailed assessment of each miner’s contribution to sustainable practices hence contributing to the greener earth. Below is a detailed description of the process of how miner Arkreen transaction activities are created daily on the permanent storage system.

4 Estimation of Arkreen PoGG Data Storage Size on Arweave’s Permanent Storage System

With 1,000,000 miners onboarded on the Arkreen Network, each generating 700MB of data every hour, so the total data uploaded to Arweave every day would be:

1,000,000 miners * 17.76KB/miner = 17.76GB per day.

Over the course of a year, this daily data generation accumulates to:

17.76 GB/day * 365 days/year = 6.46TB.

So, the Arkreen Network would upload approximately 6.5 terabytes of data to Arweave in a year under these conditions. This is a substantial amount of data and highlights the importance of efficient data management and storage solutions to handle such massive volumes.
