GEODNET (GEOD) sustainability report

GEODNET is present on the following networks: Polygon, Solana.

The Polygon blockchain network, originally known as Matic Network, operates as a Layer 2 scaling solution for Ethereum, leveraging a sophisticated hybrid consensus mechanism to enhance scalability, ensure security, and maintain decentralization. The foundational elements of its consensus protocol are built upon a combination of Proof of Stake (PoS) and Plasma Chains. Within the PoS framework, validators are selected based on the number of MATIC tokens they have staked, with a larger stake increasing their probability of being chosen to validate transactions and produce new blocks. This system also allows MATIC token holders who prefer not to run their own validator nodes to delegate their tokens to trusted validators, thereby earning a share of the rewards and actively contributing to the network's overall security and decentralization.

Supplementing PoS, Polygon utilizes Plasma Chains, which serve as a framework for establishing child chains that run in parallel with the main Ethereum chain. These child chains facilitate off-chain transaction processing, significantly improving transaction throughput and reducing congestion on the Ethereum mainnet by committing only the final, aggregated state back to Ethereum. To uphold the integrity and security of these off-chain transactions, Plasma Chains incorporate a robust fraud-proof mechanism, enabling the challenging and potential reversion of any detected fraudulent activity.

The consensus process on Polygon begins with validators confirming the validity of transactions and subsequently integrating them into blocks. Validators then propose new blocks, with their staked tokens influencing their voting power, and engage in a collective voting process to reach consensus. A new block is officially added to the blockchain upon receiving a majority of votes. A critical security measure is the periodic checkpointing system, where snapshots of the Polygon sidechain's state are regularly submitted to the Ethereum main chain, thereby leveraging Ethereum's inherent security for the finality of Polygon's transactions. The Plasma framework further enables off-chain validation of transactions on child chains, with their final states eventually submitted to the Ethereum main chain, and fraud proofs ready to challenge any suspicious transactions within a specified period, collectively reinforcing Polygon's operational integrity and security.

The Solana blockchain architecture operates through a hybrid consensus model that integrates Proof of History (PoH) with Proof of Stake (PoS). This combination is designed to optimize transaction throughput and reduce network latency while maintaining a high degree of security. Proof of History functions as a decentralized clock, using a Verifiable Delay Function (VDF) to create a permanent, timestamped record of events. This cryptographic sequence allows the network to agree on the chronological order of transactions without requiring nodes to communicate extensively, thereby solving traditional synchronization bottlenecks found in other distributed ledgers. Parallel to PoH, the Proof of Stake component manages the selection of validators and the finalization of the ledger state. Validators are chosen to act as leaders for specific blocks based on the total quantity of the native network assets they have staked. Users who do not run their own hardware can participate in network security by delegating their assets to existing validators, sharing in the rewards generated by successful block production. The consensus process begins when transactions are broadcast and collected for validation. A designated leader then generates a PoH sequence to order these transactions within a block. Subsequently, other validators in the network verify the integrity of the PoH hashes and the validity of the transactions. Once a sufficient number of signatures are collected, the block is finalized and appended to the blockchain. This dual approach ensures that the network remains resilient against attacks; validators must provide collateral through staking, and any malicious activity, such as producing invalid blocks or double-signing, can result in the loss of staked assets through a process known as slashing. This economic deterrent ensures that participants remain aligned with the network's health and operational standards.

GEODNET is present on the following networks: Polygon, Solana.

The Polygon network employs a robust set of incentive mechanisms and a distinct fee structure, combining its Proof of Stake (PoS) consensus with the Plasma framework to ensure network security, encourage active participation, and maintain transaction integrity. Validators play a crucial role, securing the network by staking MATIC tokens. Their selection for validating transactions and producing new blocks is directly influenced by the quantity of tokens they have staked. In exchange for their services, validators receive rewards in the form of newly minted MATIC tokens and a portion of the transaction fees. They are responsible for proposing and voting on new blocks, with incentives structured to promote honest and efficient operation, while also deterring misconduct through potential penalties. A key security feature involves validators periodically submitting checkpoints of the Polygon sidechain to the Ethereum main chain, which leverages Ethereum's established robustness to guarantee the finality of Polygon's transactions.

Delegators, who are token holders opting not to operate their own validator nodes, can delegate their MATIC tokens to trusted validators. This delegation allows them to earn a share of the rewards distributed to their chosen validators, fostering broader community participation in securing the network and enhancing its decentralization. The economic security of Polygon is further reinforced by a slashing mechanism, which penalizes validators for malicious actions, such as double-signing transactions or extended periods of inactivity. Slashing entails the forfeiture of a portion of their staked tokens, serving as a powerful deterrent against dishonest behavior. Additionally, validators are required to bond a substantial amount of MATIC, ensuring they have a significant financial interest in upholding the network's integrity.

Regarding the fee structure, one of Polygon's significant advantages is its remarkably low transaction fees compared to the Ethereum main chain. These fees, paid in MATIC tokens, are designed to be affordable, thereby encouraging high transaction throughput and widespread user adoption. While fees on Polygon can exhibit dynamic variations based on network congestion and transaction complexity, they consistently remain considerably lower than those on Ethereum, making Polygon an attractive option for users and developers. Deploying and interacting with smart contracts on Polygon also incurs fees, which are determined by the computational resources required. These smart contract fees are also paid in MATIC and are substantially lower than on Ethereum, offering a cost-effective environment for developing and maintaining decentralized applications (dApps). Furthermore, the Plasma framework facilitates off-chain processing for state transfers and withdrawals, with associated fees also paid in MATIC, collectively contributing to a reduced overall cost of utilizing the network.

Incentives within the Solana blockchain network are structured to ensure high performance and decentralized security. The primary participants are validators and delegators, both of whom receive financial compensation for their roles in maintaining the ledger. Validators are rewarded for successfully producing and verifying blocks. These rewards are distributed in the network's native asset and are determined by the validator's overall stake and historical performance. Furthermore, validators receive a portion of the transaction fees associated with the data processed in their blocks, which encourages them to maximize efficiency and maintain uptime. Token holders who prefer not to operate complex infrastructure can delegate their stake to professional validators. This delegation model facilitates a more inclusive security environment, as delegators earn a percentage of the rewards proportional to their contribution, thereby decentralizing the control of the network. Security is further enforced through economic penalties. The network employs a slashing mechanism where a portion of a validator's staked assets is confiscated if they engage in dishonest behavior or fail to meet network requirements, such as remaining offline for extended periods. This introduces an opportunity cost for all participants, ensuring they remain committed to honest operations. Regarding the cost of using the network, the fee structure is designed to be highly competitive and predictable. Users pay transaction fees to compensate for the computational power and bandwidth consumed by nodes. These fees are notably low, facilitating high-volume usage. In addition to transaction costs, the network implements rent fees for data storage. This unique mechanism charges for the persistence of data on the blockchain, discouraging the inefficient use of state storage and prompting developers to prune unnecessary data. Finally, smart contract execution fees are calculated based on the specific resource intensity of the code, ensuring that participants pay a fair rate for the network resources they utilize.

The methodology for assessing the Polygon network's energy consumption is primarily based on a comprehensive "bottom-up" approach, which identifies the various nodes as the fundamental contributors to the network's overall energy footprint. This detailed calculation relies on empirical data collected from diverse sources, including publicly available information platforms, open-source crawlers, and proprietary in-house developed crawlers. The key factors for estimating the hardware utilized across the network are determined by the specific requirements for operating the client software. To ensure the accuracy of these estimations, the energy consumption of the identified hardware devices is precisely measured in certified test laboratories.

An integral part of this energy accounting involves the use of the Functionally Fungible Group Digital Token Identifier (FFG DTI). This identifier is employed to accurately determine and encompass all implementations of the crypto-asset relevant to the scope of analysis. The mappings derived from the FFG DTI are regularly updated, drawing upon data from the Digital Token Identifier Foundation to maintain their currency and reliability. Information concerning the specific hardware deployed and the total number of participants within the network is based on assumptions that undergo rigorous, best-effort verification using available empirical data. It is generally assumed that participants in the network behave in a largely economically rational manner. Adhering to a precautionary principle, in situations where uncertainties exist, estimates for potential adverse impacts are conservatively adjusted upwards, ensuring a robust and cautious assessment.

Crucially, due to Polygon's architectural design as a Layer 2 scaling solution for Ethereum, its energy consumption calculation incorporates a shared security model. Consequently, a proportional share of the Ethereum network's energy consumption is also attributed to Polygon, acknowledging Ethereum's foundational role in providing security to the Layer 2 solution. This specific proportion of Ethereum's energy usage is quantitatively determined based on the gas consumption on the Ethereum network. While the documents mention reliance on "public information sites" and the "Digital Token Identifier Foundation" for data, they do not provide specific URLs for these external resources.

To calculate the energy consumption of the Solana blockchain network, a "bottom-up" methodology is utilized, placing the network nodes at the center of the analysis. This approach relies on identifying the number of active participants and the specific hardware requirements necessary to run the network's client software. Data collection involves a variety of sources, including open-source web crawlers, internal monitoring tools developed by the legal entities, and public information websites. By analyzing these data points, researchers can estimate the hardware profiles of the various nodes operating globally. To ensure accuracy, the energy consumption of typical hardware devices is measured within certified laboratory environments, providing a baseline for the power usage of each node. Furthermore, the methodology incorporates data from the Digital Token Identifier Foundation to map all implementations of the assets within the network's scope. When specific hardware data is not directly observable, assumptions are made based on the principle of economic rationality, assuming participants optimize their setups for cost-efficiency while meeting software specifications. In instances of uncertainty, a precautionary principle is applied, favoring conservative estimates that likely overstate the environmental impact rather than underestimating it. This ensures that the reported energy footprint represents a credible upper bound of actual consumption. The total network consumption is determined by aggregating the energy needs of all identified nodes, accounting for both the computational requirements of processing transactions and the energy consumed by hardware in an idle or supportive state. This rigorous framework allows for a comprehensive assessment of the network’s total power requirements over a defined reporting period, providing a transparent view of the operational costs associated with maintaining the distributed ledger's infrastructure.

GEODNET is present on the following networks: Polygon, Solana.

The available documentation details the methodologies for calculating the Polygon network's energy consumption, but it does not explicitly identify the key energy sources (e.g., renewable vs. non-renewable electricity, specific grid mixes) that power its underlying infrastructure. Instead, the focus is on the methodology of consumption assessment. The energy calculation employs a "bottom-up" approach, which considers individual nodes as the primary units of energy consumption within the network. This methodology draws on empirical findings from various data points, including public information sites, open-source crawlers, and proprietary in-house developed crawlers, to estimate the hardware utilized across the network.

The primary determinants for estimating the hardware's energy usage are the computational requirements for running the client software. The energy consumption of these specific hardware devices is meticulously measured and verified in certified test laboratories to ensure precise data collection. To accurately scope all relevant implementations of the crypto-asset for energy calculation, the Functionally Fungible Group Digital Token Identifier (FFG DTI) is utilized, with its mappings regularly updated through data from the Digital Token Identifier Foundation. Assumptions regarding the hardware in operation and the total count of network participants are diligently verified against empirical data, operating under the premise that participants are largely economically rational. In line with a precautionary principle, any uncertainties default to conservative estimates, leaning towards higher figures for potential adverse impacts.

Significantly, as Polygon functions as a Layer 2 scaling solution for Ethereum, its energy consumption calculation also integrates a portion of the Ethereum network's energy usage. This inclusion acknowledges Ethereum's fundamental role in providing security to Polygon. The specific proportion attributed is determined by the gas consumption on the Ethereum network, ensuring a comprehensive view of Polygon's energy demand, considering its reliance on the main Layer 1 chain. While these methodologies provide a clear framework for quantifying energy use, specific details regarding the actual sources of this energy are not elaborated upon in the provided documents, nor are any direct links to external documents specifying these sources or methodologies furnished.

The determination of energy sources for the Solana blockchain network involves a sophisticated geolocation mapping of the global node infrastructure. By utilizing internal and open-source crawlers, the physical locations of validator nodes are identified. Once the geographic distribution is established, this information is cross-referenced with regional energy data to calculate the percentage of renewable energy utilized by the network. For regions where specific node data is unavailable, researchers utilize reference networks that share similar consensus mechanisms and incentive structures as proxies to estimate the geographic spread of the infrastructure. The primary data source for these regional energy profiles is the Share of electricity generated by renewables dataset provided by Our World in Data, which incorporates research from Ember and the Energy Institute. This dataset provides yearly electricity data that allows for a granular assessment of how much of the network's power is derived from wind, solar, hydro, and other renewable sources. In addition to the total percentage of green energy, the methodology focuses on energy intensity, which is defined as the marginal energy cost required to process a single additional transaction on the network. This figure helps quantify the efficiency of the blockchain's resource usage relative to its utility. By integrating global energy statistics with real-time node distribution data, the network can report a more accurate picture of its sustainability, currently indicating that a significant portion of its operational energy comes from renewable sources, reflecting the broader global transition toward cleaner power grids.

GEODNET is present on the following networks: Polygon, Solana.

The provided documents offer comprehensive details regarding the methodologies for calculating the energy consumption of the Polygon blockchain network, which are predicated on a "bottom-up" approach focusing on node energy demand, hardware requirements, and the integration of a proportion of Ethereum's energy consumption due to Polygon's Layer 2 architecture. This framework is robust for quantifying electrical energy usage. However, when addressing the topic of key Greenhouse Gas (GHG) sources and their associated methodologies, the provided information is notably insufficient. The documents do not contain any specific data or discussions pertaining to the direct or indirect GHG emissions generated by the Polygon network's operations.

Crucially, there is no mention of the types of emissions (e.g., Scope 1 for direct emissions, Scope 2 for indirect emissions from purchased electricity, or Scope 3 for other indirect emissions within the value chain), nor any dedicated methodologies for calculating, monitoring, or reporting these GHG emissions. The absence of information on the energy mix that powers the network's validators and underlying infrastructure – whether it is predominantly from renewable sources, fossil fuels, or a specific national grid mix – makes it impossible to determine the carbon intensity of the energy consumed. Without such details, a comprehensive assessment of GHG sources cannot be made.

While the methodology for energy consumption includes a "precautionary principle" to make higher estimates for "adverse impacts," these impacts are not explicitly defined or quantified in terms of GHG emissions. There is no information provided on specific conversion factors used to translate energy consumption into carbon dioxide equivalents or other greenhouse gases. The documents do not offer any external links or references to dedicated environmental impact assessments or GHG reporting standards followed by the Polygon network. Consequently, based solely on the provided information, it is not possible to identify the key GHG sources or the specific methodologies employed for their quantification within the Polygon ecosystem.

Quantifying the greenhouse gas (GHG) emissions of the Solana blockchain network requires a methodology focused on carbon intensity and the geographic footprint of its decentralized nodes. Similar to the energy source analysis, the process begins by locating active nodes using a combination of public data and specialized web crawling technology. This geographic information is critical because the carbon footprint of electricity varies significantly between different jurisdictions depending on their local power generation mix. For nodes that cannot be precisely located, the analysis uses data from comparable blockchain networks to ensure the estimation remains as complete as possible. The carbon intensity of the electricity used by these nodes is derived from the Carbon intensity of electricity generation dataset, accessible via Our World in Data. This dataset, which is licensed under CC BY 4.0, provides essential metrics on the amount of CO2 equivalent emitted per kilowatt-hour of electricity produced in various countries. By merging node locations with these carbon intensity values, the network can calculate its Scope 2 emissions, which represent the indirect emissions from the generation of purchased electricity. The methodology also focuses on GHG intensity, measuring the marginal emissions generated by one additional transaction on the blockchain. This allows for a performance-based assessment of the network's environmental impact. The results are typically reported in tonnes of CO2 equivalent (tCO2e), providing a standardized metric that allows for comparison with other industries and financial systems. This data-driven approach ensures that the network’s environmental disclosures are rooted in empirical global energy statistics and verifiable infrastructure data.
