Description

Field of invention:

[0001] The present invention relates to blockchain technology in connection with ecological sustainability and in particular to a decentralized marketplace platform for small and medium-sized enterprises (SMEs). Background of the invention:

[0002] With ever-increasing global efforts to reduce CO2 emissions, there has been an explosion of regulatory requirements for reducing the carbon footprint. The complexity of emissions trading markets makes it particularly difficult for small and medium-sized enterprises (SMEs) with limited resources to navigate the market on their own. Current emissions trading platforms can be slow and opaque, leaving participants uncertain about the security of their transactions. Businesses—especially SMEs—need a decentralized, blockchain-based solution that allows them to easily buy, sell, and trade emissions certificates while ensuring regulatory compliance.This would create a public, unchanging transaction index that gives the world an honest overview of what companies are actually doing in response to their sustainable business policies.

[0003] As global awareness of climate change grows and regulatory pressure to reduce CO2 emissions increases worldwide, the market for selling emission allowances has also expanded. These so-called "carbon credits" allow companies to offset their emissions by purchasing allowance units, each representing one tonne of CO2 equivalent removed or reduced. These allowances are typically created from environmental projects such as reforestation, renewable energy production, or carbon capture (e.g., methane). While the emission allowance market offers tremendous opportunities, it remains one of the most challenging for small and medium-sized enterprises (SMEs).Existing platforms and solutions for emissions trading are mostly tailored to the needs of large companies with substantial resources, making it difficult for SMEs to gain access or transparency, as well as to have a user-friendly interface.

[0004] The problem with current emissions trading platforms is that most of them are centralized, meaning they are operated by a single authority responsible for all transactions and compliance checks. While centralization may offer control and governance, it comes at a price, limiting transparency, efficiency, and trust. These centralized platforms act as intermediaries and therefore require extensive verification processes and manual compliance checks, resulting in high administrative fees. Such costs could be prohibitive for SMEs with limited budgets, and the lengthy processes can make emissions trading unattractive for smaller businesses altogether.Furthermore, centralized platforms are a honeypot for hackers when they are shut down, as all transaction and user information is stored in one place on the central server.

[0005] This also raises transparency issues stemming from reliance on intermediaries. Most centralized platforms also lack real-time access to transaction records or detailed information on how credits are procured, verified, and valued. This last point is particularly critical, as the sector's lack of transparency poses a challenge for SMEs unfamiliar with carbon markets: they cannot assess whether they can trust each other. Consequently, SMEs rarely have direct access to government data; they typically rely on third-party verification services. The more intermediaries involved, the more complex and costly the registration process becomes. Centralized systems are also more susceptible to human error, as verification and compliance checks largely rely on manual processes.As a result, there is a higher risk that transaction records are incorrect and that disputes arise over these transactions, leading to a loss of all trust in this marketplace.

[0006] The integration of blockchain technology on some platforms aims to increase transparency and security in emissions trading. Essentially, blockchain is a decentralized and immutable record of transactions that can be used to create an unhackable ledger for all emissions trading transactions in the future. These blockchain-based platforms will help automate much of the emissions trading verification process, reducing reliance on intermediaries and manual intervention. Despite their promise, however, they are generally still relatively immature and limited in scope, focusing primarily on enterprise applications. These enterprise applications are capable of handling complex nuances and offer a higher level of functionality that requires specialized knowledge, which can sometimes be quite cumbersome, especially for small and medium-sized enterprises (SMEs).Furthermore, these blockchain offerings typically lack standard compliance checks for transactions that adhere to evolving regulatory standards. Therefore, users must continue to rely on third-party services to maintain compliance, undermining the efficiency that blockchain technology is meant to provide.

[0007] Even worse, current blockchain applications often lack easily accessible software or process customization, which is particularly problematic for SMEs. Many blockchains attempting to sell emission credits are structured for the investment market and large corporations; they expect people with an aggressive business model to get involved, even though most businesses don't even have that luxury. Accessibility features are lacking, and there's no authenticity in the processes, making these platforms unattractive to SMEs. This complexity is also why, given all these concerns, fewer smaller businesses are interested, but this is a learning curve.What happens is that SMEs consequently accumulate a significant collective greenhouse gas footprint - they have been and continue to be poorly served in the emissions credit market because current technologies / platforms simply cannot serve them efficiently.

[0008] Current solutions also lack transparent pricing for CO2 certificates. These traditional marketplaces obscure the reasons for CO2 certificate price fluctuations, the driving forces on the supply and demand sides or within regulatory bodies, and the true effectiveness of our actual, rather mysterious, carbon offsetting projects. This often results in SMEs overpaying for information or not knowing when to spend money (or even how much they can afford), with far-reaching implications for sustainability and financial health. While blockchain platforms can eliminate opaque ledger records, they may lack a live pricing engine that provides SMEs with insights into market trends and price movements.Without this function, SMEs cannot gain insights from data about when the right time is for them to buy / sell / hold CO2 certificates.

[0009] A major drawback of existing blockchain implementations is that none of them perform automated compliance checks. Emissions credit markets are heavily influenced by regulatory standards, and there are significant regional variations as well as differences depending on the type of emissions offsetting project. Regarding compliance, many other platforms rely on manual updates and interventions to adapt, which introduces both delays and the risk of non-compliance. It can be difficult for SMEs to keep pace with these changes, especially if the platforms they use lack compliance capabilities. Without this capability, SMEs risk inadvertently participating in non-compliant transactions, and the penalties can be devastating for smaller businesses with fewer resources.

[0010] Furthermore, blockchain technology has not yet been able to realize a clear opportunity in the emissions trading markets due to scaling issues. Many modern blockchain platforms today—especially those based on a proof-of-work (POW) consensus model—can be resource-intensive and slow in data exchange or transaction completion. These networks also exhibit significant fluctuations in transaction costs, as they depend on the current traffic of each network, creating greater uncertainty for SMEs. These scalability issues pose a challenge for blockchain-based platforms, as they need to process large volumes of transactions without significant delays or increased costs.As a result, existing solutions may not be able to cope with the increasing participation of SMEs, which likely limits blockchain-based emission allowance trading in both its scalability and its general acceptance.

[0011] Most current blockchain solutions remain too complex, fail to provide a genuine solution for automated regulatory compliance, and are simply another solution intended for adoption (or complete adoption) by established large corporations. This has resulted in a lack of user-friendly interfaces, a lack of real-time pricing transparency, and the integration of monitoring devices within these platforms makes them even more challenging for smaller-scale businesses. Summary of the invention:

[0012] The present invention is a blockchain-based emissions credit marketplace system for SMEs that enables the secure use, sale, and exchange of CERs in a transparent and decentralized manner. The system consists of a decentralized blockchain network with many interconnected nodes responsible for validating and recording transactions. It includes a smart contract-based blockchain platform for the automatic verification of emissions credits and features an integrated compliance module for regulatory standards. This allows SMEs to enter the emissions credit market via an intuitive marketplace interface, with the assurance that every transaction is secure and transparent.

[0013] The invention's design encompasses a transaction-based carbon credit system and a verification process that operates discriminatorily. It features a computerized compliance module that verifies all transactions according to regulatory standards, ensuring not only security but also compliance with increasingly stringent regulations. Furthermore, a blockchain-based carbon credit ledger is maintained to verify transactions, providing an immutable and transparent record of all actions. The system also includes a marketplace interface for accessing information and purchasing transactions, tailored for use by SMEs and promoting their participation in carbon offsetting programs.

[0014] Therefore, an objective of the present invention is to provide a blockchain-based marketplace system for emission credits that enables small and medium-sized enterprises (hereinafter referred to as "SMEs") to actively participate, while preventing fraudulent activities by others and allowing all or nearly all amounts to be transferred securely between countries. The invention aims to overcome the obstacles that prevent small businesses from participating in standard emission credit markets by providing a networked marketplace that improves accessibility, fairness, and transparency while eliminating intermediaries.The invention aims to use blockchain technology, which results in all transactions for emission credits being recorded in an immutable ledger, enabling SMEs to buy and sell, validate or trade their emission credits with complete transparency. Brief description of the character: Fig. Figure 1 shows a block diagram of a blockchain-based marketplace for emission allowances for small and medium-sized enterprises (SMEs) according to an embodiment of the present invention. Detailed description of the invention:

[0015] Fig.Figure 1 shows a block diagram of a blockchain-based marketplace for CO2 credits for small and medium-sized enterprises (SMEs), comprising: a decentralized ledger unit 102 configured to securely and transparently record transactions involving CO2 credits, the ledger unit being operationally connected to a variety of SME user devices to enable trading activities; a credit verification processing unit 104 connected to the decentralized ledger unit and structured to automate the verification of CO2 credits based on regulatory standards, the credit verification processing unit including an audit component to ensure the validity of the traded CO2 credits;an automated compliance monitoring unit 106, which is connected to the credit verification processing unit and is structured to ensure that all transactions meet predefined regulatory requirements, wherein the compliance monitoring unit is equipped with a real-time alert module to notify SMEs of any non-compliance issues; a marketplace interface unit 108, which the SME user devices can access and which is configured to facilitate the purchase, sale, and trading of CO2 credits, wherein the marketplace interface unit is further configured to provide real-time updates on the prices and availability of CO2 credits;a transaction encryption unit 110, which is operationally connected to the decentralized ledger unit, wherein the transaction encryption unit is structured such that all trading activities are secured with a cryptographic mechanism, thereby ensuring data protection and transaction integrity within the marketplace; and an analytics module 112, which communicates with the marketplace interface unit and is designed to provide SMEs with insights into their CO2 credit usage and potential sustainability improvements based on trading history and credit usage patterns.

[0016] In one embodiment, the decentralized ledger unit 102 comprises a distributed node structure to prevent single points of failure and to improve transaction transparency across all user devices.

[0017] In one embodiment, the compliance monitoring unit 106 also includes a smart contract delivery component that is structured to automate regulatory checks and execute transactions only upon successful compliance verification.

[0018] In one embodiment, the marketplace interface unit 108 includes a function for classifying emission credits, which is configured to classify emission credits based on factors such as origin, verification status and impact on sustainability, thereby enabling SMEs to make informed trading decisions.

[0019] In one embodiment, the transaction encryption unit 110 uses a consensus mechanism selected from a group consisting of Proof-of-Work, Proof-of-Stake, and Delegated Proof-of-Stake, and adapted to ensure secure and decentralized validation of all transactions within the system.

[0020] The emissions credit marketplace is a decentralized blockchain network that processes all transactions for buying and selling these emissions credits. This network consists of countless nodes, each with a smart contract verification processing unit (SPU). Data inputs are written to smart contracts that comply with legal standards for issuing emissions credits. The transaction is then verified by the SPU on each node, and only valid transactions that do not violate any rules are recorded on the blockchain, where cryptographic techniques are used for secure and efficient transaction validation.

[0021] An emissions credit ledger stored on the blockchain network acts as a distributed database that immutably records every transaction. The ledger ultimately generates unique, hash-based identifiers for each individual transaction processed on it. Therefore, the data entries it contains are highly secure and cannot be manipulated if forged or duplicated, just as a mouse in Windows searches for its cursor. Transparency: This distributed ledger structure will provide transparency, allowing all participants in the network, including SMEs and regulators (where authorized), to view transaction histories, ensuring that every single emissions credit is verifiable.

[0022] Features like the automated compliance module are integrated to ensure adherence to regulatory standards. It communicates with the verification processing units within the nodes and is configured to automatically verify transactions based on regulatory requirements. The compliance module also includes a regulatory update function that dynamically retrieves updates to carbon emission standards from reliable sources. This guarantees that no manual updates are required to keep pace with current regulations. Through these standards, the compliance module provides real-time alerts if a transaction violates the rules, ultimately helping SMEs avoid future complications. This allows regulators to view flagged transactions in the compliance module and hold the parties accountable.

[0023] The invention also includes a marketplace interface designed to support SMEs on an expanded trading platform, enabling them to conduct large-scale transactions. The interface ensures secure access using robust authentication protocols, so that only authorized users can view current information on emission allowance availability, market trends, transaction history, and so on. SMEs can initiate transactions, buy / sell emission allowances directly through the interface, or trade them. For example, an algorithm integrated into the interface is a dynamic pricing engine that considers current supply and demand trends as well as transaction volume when calculating emission allowance prices.Using predictive algorithms and real-time forecasts, this intelligent forecasting engine predicts market changes, enabling SMEs to make smarter trading decisions. The interface also includes an analytical dashboard displaying transaction volumes, compliance statistics, and CO2 offset metrics to give SMEs an overview of their emissions trading activities.

[0024] It also supports the integration of carbon monitoring devices located outside your region. In practice, the data is sent directly from these savers to a blockchain and verified by the associated processing unit against what is available in the emissions credit network. This feature ensures that the emissions credits align with actual environmental impact data, ultimately further validating and securing the market.

[0025] An exemplary embodiment of the present invention provides a system that can be implemented, at least partially, using a device structure consisting of a decentralized server network, a defined number of blockchain nodes, and a marketplace interface device. The blockchain is operated by a decentralized server network, allowing the nodes (each with its own verification computing unit) to sit between the execution of smart contracts and transaction validation. The human interface device for the marketplace is a touchscreen that enables users to securely control access remotely. Its device structure integrates third-party carbon monitoring devices via specific ports and wireless communication protocols, thus facilitating the easy transfer of data to a blockchain platform.

[0026] In at least some aspects, the present invention addresses the transport demand from small and medium-sized enterprises (SMEs) for affordable CO2 offset payments. The invention utilizes blockchain technology to bring greater transparency, security, and trust to the emissions trading process. It has the capability to automatically verify and check compliance with levels, a clear objective of streamlining the process for SMEs wishing to participate in emissions trading markets without having to grapple with regulatory intricacies. A user-friendly and informative marketplace interface provides the tools and insights that SMEs need to make data-driven trading decisions.Furthermore, the reliability of this solution is demonstrated by its compatibility with external carbon monitoring devices, which makes it possible to integrate it into a wide range of devices in real-world implementation, thus strengthening the robustness of the entire ecosystem for emissions trading.

[0027] According to one embodiment, the present invention provides a blockchain-based decentralized transaction system for CO2 credits for SMEs. The network is secure and robust because it has multiple tandem nodes that jointly verify a transaction and record identical data. All nodes are autonomous within the network, so no single piece of hardware becomes a single point of failure, thus enabling secure transactions. This approach allows for a more efficient and robust method of verifying transactions, since only the two nodes on each side can "see" them. For example, if a single node is business-related and all other nodes are functioning correctly to provide identity and data, a compromised node cannot disrupt your entire system, thus protecting your entire IT system.

[0028] In one example, each node includes a verification processing unit configured to execute smart contracts that automatically validate carbon credit transactions. These smart contracts define sets of rules (such as compliance with a specific regulatory standard) or thresholds that the transaction must meet, allowing only valid transactions on that part of the blockchain. For instance, if an SME attempts to purchase a carbon credit, the smart contract would verify that the credits meet specific environmental criteria for that type before allowing the purchase. Less room for error also translates to a lower risk of fraud, a higher level of trust, and the assurance that SMEs are only participating in legally compliant transactions.

[0029] The emissions credit ledger, in one example implementation, aggregates the transactions that power the blockchain and cryptographically secures them to ensure their immediacy. Every transaction that takes place in this ledger is time- and transaction-ID-specific, making the entire process transparent (attributes and traceability). By recording this information on the blockchain, unauthorized changes are prevented, and a record is stored for each transaction. For example, an SME that needs to demonstrate its carbon offsetting activities when reporting to a regulatory authority can use the ledger as proof of its activities. This means that all participants can see each other's data, which builds trust and facilitates third-party audits.

[0030] According to one embodiment, the system also includes an automated compliance module directly connected to a verification processing unit. This module continuously analyzes transaction data against regulatory requirements, and if it detects inputs not already defined in predefined standards, an alert or notification is forwarded to the relevant systems. For example, if a new regulation stipulates that emission credits may only be obtained from specific project types, the compliance module performs this automated check for each transaction. It can alert small and medium-sized enterprises (SMEs) with non-compliant transactions in real time, allowing them to correct or stop the transaction. Furthermore, regulatory bodies can view their non-compliant transactions on a blockchain and maintain a control system through the recording of audits.

[0031] In one example, the marketplace interface can be tailored to small and medium-sized enterprises (SMEs) to provide a simple way to trade emission allowances with defined security. This interface displays real-time information on emission allowance availability, transaction history, and market trends to help SMEs make informed trading decisions. Users can use the interface to buy, sell, and trade emission allowances, which are verified through a network of linked blockchains. It employs secure authentication methods to protect the application and grant access to the marketplace only to users with a legitimate need for the services.This means that a small or medium-sized company could use something like two-factor authentication to log in only with general accounts and thus never gain access to the specific details.

[0032] In one embodiment, the carbon source authentication submodule of the verification processing unit is able to authenticate and verify the origin and type status details of carbon credits before they are validated for trading. This increases the legitimacy of the traded credits and reduces potential fraud.

[0033] In one embodiment, the automated compliance module also includes a regulatory update mechanism that keeps your system up-to-date with changing carbon emission standards. This mechanism automatically updates with the latest government regulations that determine whether thrive remains compliant. For example, if new legislation mandates stricter guidelines for renewable energy projects, this compliance module would immediately incorporate these checks into its validation process. This functionality enables compliance with changing regulatory requirements without manual intervention, saving time and reducing the likelihood of human error in compliance.

[0034] Accordingly, in one embodiment, the emission credit ledger also includes a multi-signature protocol, as it may be desirable to have multiple nodes confirming that all parties agree with what is being recorded. This is used to increase security and prevent double-spending by ensuring that no single node can authorize a transaction on their behalf. For example, a purchase initiated by an SME must be approved by multiple nodes before the transaction can take effect. This distributed validation process helps to strengthen trust and reduce the likelihood of fraudulent activity.

[0035] In one embodiment, the marketplace interface also utilizes a dynamic pricing engine to determine the market value of emission allowances based on supply and demand trends, transaction volume, and allowance type. The model employs machine learning algorithms to predict the market price, enabling SMEs to implement trading strategies that maximize their profitability. For example, the engine could use historical data to recommend when an SME should buy or sell allowances to minimize costs for cost savings or potential profits. The pricing engine provides data-driven insights that allow SMEs to make informed decisions and remain strategic in a volatile market.

[0036] In one embodiment, transactions are validated by each node in a system that includes at least one module of the consensus mechanism; this submodule also uses a proof-of-stake protocol. The system implemented by this protocol uses validators according to their participation in the network, which is more diverse than a blacklist with only single roles. For example, if the network detects an increase in transaction volume, such a submodule can switch between node selection criteria to better distribute the workload and ensure that transactions are processed at maximum speed without compromising reliability. The system can scale as more SMEs participate in the emissions trading marketplace, leading to an increasing transaction load.

[0037] With the additional audit trail module, SMEs can generate detailed reports on their carbon credit transactions, helping them comply with environmental regulations. For example, an SME could use the audit trail module to create a report for its annual sustainability review, which would support carbon credit activities and demonstrate compliance with the relevant standards. This data set cannot be manipulated in any way, further increasing the transparency and accountability of this audit trail.

[0038] In one implementation, the marketplace interface includes an analytical dashboard that leverages information from across the blockchain network and reports metrics such as transaction volume, carbon offsetting figures, and compliance statistics. In a sample use case, a small to medium-sized enterprise (SME) could graphically view its carbon offsetting activities from the past year on the dashboard and assess its sustainability goals by identifying areas for improvement. The dashboard provides a clear and comprehensive overview of the SME's activities and supports data-driven decision-making.
