Description

[0001] Content management method, content management system, metaverse and computer program product

[0002] State of the art

[0003] The invention relates to a content management method according to the preamble of claim 1, a content management system according to the preamble of claim 20, a metaverse according to claim 22 and a computer program product according to claim 23.

[0004] In the context of popular projects such as Decentraland, a type of location-based decentralized content management method for managing digital content within a metaverse linked to a blockchain (there: Ethereum blockchain) has already been proposed, whereby a virtual space defined by the metaverse is divided into a number of adjacent segments, and whereby the digital content can be assigned to individual segments.

[0005] The object of the invention is, in particular, to provide a generic method with advantageous properties in terms of versatility, design freedom, and / or user-friendliness. This object is achieved according to the invention by the features of patent claims 1, 20, 22, and 23, while advantageous embodiments and further developments of the invention can be found in the subclaims. Advantages of the invention

[0006] The invention is based on a, in particular computer-implemented, content management method (CMV), in particular a computer-implemented location-based, preferably decentralized, content management method at least for managing digital content within a metaverse linked to a distributed ledger technology (DLT), such as a blockchain or a tangle, wherein a virtual space defined by the metaverse is divided into a number of segments arranged next to one another and / or one above the other, in particular volume segments, and wherein digital content is assigned to individual segments.

[0007] It is proposed that at least one of the segments be assigned a Decentralized Autonomous Organization (DAO, hereinafter referred to as VolumeDAO) based on the DLT. This can advantageously achieve properties in terms of versatility, design freedom, and / or user-friendliness. This can advantageously achieve a high level of transparency of the CMV, in particular by making the rules and governance of the CMV within each of the segments accessible and / or traceable to everyone (an immutable, transparent audit trail). Furthermore, a high level of transparency can advantageously be achieved by hard-coding the governance of individual segments in immutably DLT-based smart contracts.Furthermore, a high degree of versatility and / or design freedom can be advantageously achieved by enabling (democratic) participation in processes in the individual segments for everyone at any time. For example, an existing smart contract assigned to a segment's VolumeDAO can advantageously be replaced by a vote among the VolumeDAO participants. Advantageously, no overarching administrative and / or control structure is necessary to organize the CMV. Advantageously, external influences that extend beyond the CMV, for example, through manipulation or censorship of digital content, or similar, can be at least largely prevented. This can, for example, enable a search function for locating digital content that can only be influenced to a very limited extent. Furthermore, decentralization can advantageously be achieved, which can advantageously reduce susceptibility to system failures.Advantageously, a direct implementation of a content management process can be achieved, free of intermediaries, particularly in the payment of services and / or content sharing. This can advantageously achieve high levels of efficiency, particularly cost-effectiveness and / or energy efficiency.

[0008] In a particularly location-based, preferably decentralized, content management method, digital content is managed, i.e., for example, provided, which is linked, in particular virtually, to at least one coordinate in a metaverse and / or to a location coordinate. The content management method is preferably also provided for incorporating digital content into a content management system (CMS). Digital content can be embodied as a digital image file, a digital video file, a digital sound file, a digital character string, a digital key, a digital computer program (app), a digital text, or the like. In particular, the content management method is provided for providing the digital content in such a way that it can be played back by a user's playback device.In particular, the management and / or provision of the digital content takes place via a smart contract, which is preferably assigned to the VolumeDAO of the respective segment. In particular, before the digital content is uploaded, accessed, or played, the user interacts with the VolumeDAO smart contract. A single smart contract of the respective Volume DAO can organize / manage the provision of multiple digital content items within a segment, or each digital content item or subset of all digital content items within one of the segments can be assigned its own, particularly individual, smart contract of the respective VolumeDAO. In particular, the result of the interaction with the VolumeDAO smart contract determines whether the digital content is made available to the user for use or not.Preferably, the VolumeDAO and / or the smart contract is set up on a DLT based on a Directed Acyclic Graph (DAG) architecture, such as IOTA™. Advantageously, the VolumeDAO and / or the smart contract is set up on a DLT that is free or almost free of transaction costs. Advantageously, the VolumeDAO and / or the smart contract is set up on a DLT that is at least essentially free of any limitation on transaction throughput. Alternatively, however, other DLTs are also conceivable, e.g., smart contract-capable blockchains such as Ethereum, EOS, Stellar, Solana, Avalanche, Fantom, Cronos, Polygon, Algorand, Chainlink, Binance Smart Chain, and many more. Advantageously, the VolumeDAO's smart contracts are publicly visible and immutable because they are set up on the DLT.

[0009] A "smart contract" is understood in particular to be a contract based on the DLT, which comprises at least one, preferably a plurality of if / then conditions as pre-programmed functions that can be called. For this purpose, "if" conditions are provided to the smart contract as input, and the smart contract reacts by outputting / non-outputting "then" results. In particular, the smart contract is designed as software code based on the DLT. In particular, the smart contract is immutable due to its DLT implementation. In particular, a DLT address in the DLT is assigned to the smart contract. In particular, the smart contract can be called by sending transactions to the DLT address of the smart contract ("write").In particular, execution of the smart contract may require payment of a fee, which is added to the transactions that call the smart contract in the form of DLT tokens of the DLT, in particular governance tokens of the respective VolumeDAO. In particular, the smart contract is executed after being called by more than one DLT node (“quorum”) of the DLT, whereby the result is only output if all members of the quorum reach the same result. Preferably, after receiving a DLT transaction triggered by the user, the smart contract carries out the following steps: a) Verifying the existence of the functions to be called in the smart contract according to the information received with the DLT transaction, if necessary with a plausibility check of the parameters, b) Verifying whether sufficient fees in the form of DLT tokens have been received, if necessary.Excess fees are returned; c) preparing a transaction to one or more DLT addresses of the DLT network, in particular at least to the DLT address from which the smart contract was called, whereby the transaction comprises, for example, access permission to digital content or permission to upload digital content, etc.; and d) executing the transaction. "Intended" is understood to mean, in particular, specifically programmed, designed, and / or equipped. The fact that an object is intended for a specific function is understood to mean, in particular, that the object fulfills and / or executes this specific function in at least one application and / or operating state.

[0010] A metaverse should be understood in particular as a consistent and persistent digital / virtual space. In particular, the digital / virtual space of the metaverse arises through a convergence of virtual and / or augmented and physical reality. In particular, the virtual space of the metaverse is divided into segments, whereby the segments can have various shapes, such as a cube, a six-sided prism, a pyramid, or any other solid shape that can be used to fill a space seamlessly. The segments can be identically shaped and identically sized; however, it is conceivable that individual segments can be further branched into sub-segments and / or that the segments are at least partially of different sizes and / or shapes. This could, for example, be determined by a smart contract of a VolumeDAO, which would then be superior to sub-VolumeDAOs of individual sub-segments.This advantageously makes it possible to nest ever smaller metaverses to any desired depth. Alternatively or additionally, it is also conceivable that VolumeDAOs of individual segments are connected and / or linked to one another through decisions made in the VolumeDAOs (e.g., via corresponding shared smart contracts). In this way, individual sub-metaverses of the metaverse can merge with one another. In particular, digital content assigned to a particularly large object, such as a building, can also be assigned to multiple volume segments, and thus in particular to multiple VolumeDAOs. The segments advantageously do not overlap with one another. The segments advantageously cover at least one interesting area, e.g., an area of ​​the globe accessible to humans, without gaps.

[0011] A "Decentralized Autonomous Organization (DAO)" is, in particular, a technical organizational structure whose governance is anchored in various smart contracts based on a DLT, which are then executed when certain predefined conditions are met. Governance in a DAO is fundamentally different from a CEO who makes decisions. Governance in a DAO requires, in particular, democratic consensus, which is hard-coded into the DAO's smart contract(s). In principle, every VolumeDAO can also be provided with a fixed value system, for example, a higher-level DAO. This is, in particular, an overarching set of rules that applies to all segments / VolumeDAOs of the CMS / CMV. It is possible that not all rules are applicable to all segments / VolumeDAOs, but no segment / VolumeDAO can violate these rules.For example, such a higher-level rule could be: "Hate speech is not allowed." This rule would then apply everywhere. For example, such a higher-level rule could be: "Advertising is not allowed in public buildings or churches." This rule would then apply to segments within churches, but not to segments within shopping malls. The rules of the fixed value system are advantageously programmable. For example, if a new VolumeDAO is created, e.g. because content is added, the VolumeDAO pulls the corresponding set of rules from the CMS / CMV or the parent DAO based on its geographical position. Alternatively or additionally, it is conceivable that the users participating in the respective volume (owners of governance tokens of the respective Volume DAO) determine the nature of the real space in a certain segment (e.g., if it isThe VolumeDAO can determine the specific situation (e.g., a school or a church?) through voting within the VolumeDAO and thus, in particular, also determine the fundamental rules of the VolumeDAO. To prevent misuse, it is conceivable that the CMS / CMV or the parent DAO has a veto right for each of the VolumeDAOs, which can only be used, for example, if a minimum number of complaints are received via a report button. Auditors from the CMS / CMV or the parent DAO can also be deployed to travel to a disputed location and examine the conditions on site.

[0012] It is further proposed that the CMV comprises the following procedural steps: a1) receiving new digital content uploaded to / from one of the segments, in particular via the DLT or a2) receiving information that digital content has been uploaded to / from a segment and b) checking whether a Decentralized Autonomous Organization (VolumeDAO) assigned to this segment and based on the DLT already exists and c) creating a new VolumeDAO for the segment within the DLT if no VolumeDAO assigned to the segment yet exists. This can advantageously achieve a simple, efficient and / or user-friendly implementation of the CMV. In particular, when the new VolumeDAO is created, it can automatically be assigned a standard smart contract defining the new VolumeDAO or a bundle of interacting standard smart contracts defining the new VolumeDAO.Alternatively or additionally, when creating the new VolumeDAO, the user who uploaded the first digital content to the segment can be provided with a selection of pre-defined initial smart contracts defining the new VolumeDAO. The smart contract(s) determined by the user's selection can then be assigned to the new VolumeDAO and define the new VolumeDAO. Alternatively or additionally, when creating the new VolumeDAO, the user who uploaded the first digital content to the segment can be prompted to provide a custom smart contract defining the new VolumeDAO. The user can then provide one or more custom smart contracts, which can then be assigned to the new VolumeDAO and define the new VolumeDAO.In particular, the prepared or automatically provided standard smart contracts and / or initial smart contracts can also be designed to be modifiable and / or adaptable by the user uploading the first digital content in the segment when creating the VolumeDAO.

[0013] If the virtual space is superimposed on the real existing space and in particular spans at least the globe, a metaverse can advantageously be provided with a reference to the real world. This can advantageously achieve a particularly comprehensive and large amount of information. This can advantageously be used to implement location-based CMV. Digital content, e.g. information, can advantageously be linked to a spatial component. The digital content can advantageously be spatially positioned in three dimensions. This can advantageously create a decentralized three-dimensional knowledge space which can in particular be filled with free knowledge created by anyone. In this case, a search can advantageously be refined and / or improved using spatial information.For example, the three-dimensional knowledge space comprising spatial information could be searched more specifically by search engines or intelligent Web 4.0 AI search bots, since information is linked to spaces. The virtual space can also be located and / or defined, at least in part, within the globe. In particular, the CMS / CMV comprises a bijective mapping at least between a part, in particular a practically visitable part, of the real space and the virtual space. In particular, the virtual space and the real space are bijectively mapped to each other, at least in parts of the totality of the real space. In particular, there exists, preferably limited to parts of the totality of the real space, e.g.limited to "interesting" parts or practically visitable parts of real existing space, a bijective mapping between volume elements of the physical world / the material universe and the segments of the virtual world / virtual space. For example, the three-dimensional recording space could be composed / constructed as follows. First, the globe plus approximately 10 km of height is inserted into a cube. This cube is then divided into, for example, 1 m x 1 m x 1 m sub-cubes (segments). With a diameter of the globe of approximately 12,756 km, the cube would then have an edge length of approximately 12,800 km and would have approximately 12,800 x 12,800 x 1,000 = 2,097,152,000,000,000 sub-cubes. Subcubes that are located in inaccessible places below the Earth's surface, e.g. subcubes within a globe radius minus 10 km depth (to include underwater objects, caves, etc.)to be able to encompass the entire system), would then be disregarded, and all other subcubes would then be assigned a unique DLT address. This would result in approximately 2,097,152,000,000,000 - 12,700 x 12,700 x 12,700 x 1,000 = 48,769,000,000,000 subcubes with DLT addresses. These subcubes with DLT addresses then form the individual segments, particularly volume segments, in this example. The totality of all subcubes with DLT addresses then forms the three-dimensional recording space in this example. Of course, more limited (e.g., limited to only one building) or three-dimensional recording spaces outside of the Earth (e.g., spanning the moon, etc.) are also conceivable. Of course, finer or coarser resolutions of the three-dimensional recording space into segments, especially volume segments, than the 1 cubic meter cube are also conceivable.For example, starting from the center of the earth, cuboid-shaped structures of increasing size could be created using imaginary laser beams, which would be approximately 1 m. 3 They have spatial volumes at the Earth's surface, but become increasingly larger with increasing distance from Earth. The segments, especially volume segments, of the three-dimensional recording space advantageously form a clean spatial search grid for search engines and / or AI search bots.

[0014] Furthermore, it is proposed that each piece of digital content be linked to at least one smart contract belonging to the VolumeDAO belonging to the segment to / from which the digital content was originally uploaded. The digital content can also be made available to other users via a smart contract of this VolumeDAO. This can advantageously achieve a high level of user-friendliness, in particular by ensuring particularly high levels of transparency regarding the origin of content and / or remuneration flows. Advantageously, a direct implementation of a content management process can be achieved, which is free of intermediaries, particularly when it comes to remuneration for services and / or sharing content.

[0015] Additionally, it is proposed that, upon receipt of the uploaded digital content, the digital content be assigned to the respective segment in the virtual space by locating the user and / or interface device initiating the upload in the real space overlaid by the virtual space. This advantageously enables location-based CMV to be implemented. Digital content, e.g., information, can advantageously be linked to a spatial component. The user's location can be determined using a location function of a user device, e.g., an interface device of the user that allows uploading and / or playing of the digital content. Global positioning using navigation satellite systems (GNSS), such as GPS, etc., is conceivable., or local positioning using positioning methods that are independent of navigation satellite systems, such as local triangulation with anchor stations, e.g. via ultra-wideband (UWB) signals, or similar, or local time-of-flight measurements, etc. Alternatively, it is conceivable that a user proves his presence in a certain segment by reading a tag positioned at the associated location and linked to the segment, e.g. a QR code, a DataMatrix code, or a barcode. It is conceivable that, depending on the strength of the evidential value of the localization, e.g. based on the localization method used by the respective user, the NFTs assigned to this user (e.g. FollowerNFT or CreatorNFT) are assigned a certain different reputation level. For example, IEEE802.15.4z (UWB) and cryptography, a particularly conclusive and / or tamper-proof distance measurement to one of the anchor stations can be implemented, which advantageously allows the highest possible reputation level to be achieved for localization data. For example, a (spoofable) localization using GNSS can be assigned a lower reputation level. It is conceivable that a reputation level can be increased / improved, e.g., through certain user activities. For example, the number of visits to a segment, the frequency of visits to a segment, or the number or frequency of visits to neighboring or (thematically or geographically) related segments can lead to an increase / improvement in the reputation level.For example, a new NFT for a person in a segment assigned to a church can be assigned a higher reputation level if that person has demonstrably already visited a large number of churches and / or already demonstrably owns a larger number of NFTs assigned to other "church segments." The digital content can be made available to other users of the CMV using the method described in the German patent application with application number 10 2022 107 027.1, the description of which is hereby incorporated in its entirety into the present patent application. Furthermore, it is proposed that a Creator Non-Fungible Token (CreatorNFT) be generated within the DLT in response to the upload of the digital content from the segment. This advantageously enables a secure, unforgeable, and / or easily traceable assignment of digital content.In particular, the CreatorNFT is linked to the respective digital content that caused its creation. In particular, by proving ownership of the CreatorNFT, a user can prove ownership and / or right of disposal over the associated digital content. It is conceivable that additional information / metadata, such as a timestamp, a usage fee, a license claim, etc., could be attached to the CreatorNFT. Adding tags such as the timestamp when uploading the content can advantageously enable a time-based content search within a segment, particularly in addition to a location-based content search.

[0016] It is also proposed that the digital content be linked to the CreatorNFT. This can advantageously enable a secure, unforgeable, and / or easily traceable assignment of digital content. A non-fungible token (NFT), sometimes also called a non-exchangeable token, is understood in particular to be a digitized form of a data set / asset that is preferably based on a DLT, such as a blockchain or a Tangle or the like, and which is in particular not one-to-one interchangeable, non-divisible, and unique. NFTs can be distributed and / or sent within the VolumeDAO and / or within the DLT. In public DLTs, the NFTs based thereon and preferably transactions associated with the NFT can be viewed by anyone. An NFT can in particular be linked to at least one physical or digital object, such as digital content.In particular, the CreatorNFT created in response to the upload of the digital content from the segment is linked at least to the uploaded digital content. To this end, the CreatorNFT includes the digital content directly or in the form of a hash value created based on the digital content, or the like. Once the creation of the CreatorNFT has been confirmed by the consensus protocol of the respective DLT, the assignment of the digital content to the CreatorNFT is immutable and permanently recorded in the DLT (until possible cancellation or destruction by an owner of the CreatorNFT). The creation of an NFT, in particular an NFT linked to an object / digital content, is often also referred to as "minting" the NFT. In particular, the CreatorNFT is created by the smart contract of the VolumeDAO or the parent CMV. Destruction of an NFT orMaking it impossible for anyone to own the NFT is often referred to as "burning" the NFT. Triggering an NFT, i.e., breaking the connection between the NFT and its associated object, is often referred to as "redeeming" the NFT. In particular, the Creator NFT can be created using the smallest possible unit of a DLT token. The DLT token forms an underlying asset. For some applications, the underlying asset can also be increased, for example, by including the actual value of the digital content at the time of creation, etc.

[0017] Creator NFTs are preferably assigned to at least one, preferably exactly one, owner address within the DLT. Alternatively, however, it is also conceivable that a Creator NFT is linked to more than one DLT owner address or that multiple users have access to a single DLT owner address and thus to the Creator NFT. This owner address assigned to the Creator NFT can be changed, for example, by sending, trading, or exchanging the Creator NFT. Alternatively, however, the Creator NFT can also be designed so that it cannot be sent. The DLT is preferably designed as a decentralized DLT. Alternatively, the DLT can also be only partially decentralized (distributed across a few nodes) or centralized. The DLT is preferably designed as a publicly accessible DLT. Alternatively, it is conceivable that the DLT has at least one access restriction. Preferably, the NFT is publicly accessible via the DLT.Preferably, the owner address assigned to the NFT is publicly visible via the DLT. Preferably, the assignment of the NFT to the owner address is publicly visible via the DLT.

[0018] If the CreatorNFT forms a VolumeDAO governance token, and in particular if the created CreatorNFT is sent to a DLT address of the DLT assigned to a user who uploaded the respective digital content, local self-management of the digital content can be advantageously enabled, particularly by users associated with the respective segment. A governance token is, in particular, a DLT token that gives its holder (the user with access to the DLT address assigned to the governance token) the ability to influence decisions concerning the rules and / or organization of the DAO (the VolumeDAO of the respective segment in which the CreatorNFT was created), in particular a core protocol of the DAO and changes to the DAO's governance parameters.In particular, the governance tokens grant relative voting power within the respective VolumeDAO, which preferably depends on a user's share of the total number of governance tokens held by a user (which may be expanded by minting new governance tokens upon uploading additional digital content). For example, each user receives one vote in the VolumeDAO for each governance token under their control. Furthermore, it is conceivable that each holder of a minimum number of governance tokens receives the right to propose certain topics for voting within the VolumeDAO. It is conceivable that the voting power of an NFT (CreatorNFT / FollowerNFT) within the VolumeDAO directly depends on the reputation level assigned to the respective NFT upon its creation.

[0019] Additionally, it is proposed that for each additional piece of digital content uploaded within the segment, an additional CreatorNFT be created within the DLT, which is specifically linked to the respective additional digital content and also constitutes a governance token of the VolumeDAO. This advantageously creates a self-managed ecosystem of content management systems with segment-specific regulations. This can advantageously achieve a high degree of flexibility and / or user-friendliness. It is conceivable that the total number of governance tokens per VolumeDAO is limited or unlimited, or that a limit on the total number of governance tokens can be determined by voting within the respective VolumeDAO itself.

[0020] If the segments, in particular the digital content assigned to the segments, in particular the CreatorNFTs comprising the digital content, are remotely searchable, a three-dimensional knowledge space can advantageously be created that can be searched more specifically, for example, by search engines or intelligent Web 4.0 AI search bots. For example, the CreatorNFTs can be searched similarly to a DLT-based NFT marketplace search. This can enable an independent, tamper-proof, and / or censorship-free search option within the metaverse. The "remotely searchable" nature of digital content should be understood in particular to mean that the digital content and / or its associated CreatorNFTs can be searched from outside the respective segments, in particular by machines and / or users located in the real space outside the respective segments.

[0021] It is also proposed that at least one of the segments be assigned a user, in particular an additional user, as a follower, in particular through the method steps a) receiving a registration of a new follower for one of the segments, for example through a higher-level smart contract of the metaverse, b) checking whether a VolumeDAO assigned to the segment and based on the DLT already exists, and c) creating a new VolumeDAO for the segment within the DLT if no VolumeDAO assigned to the segment yet exists. This can advantageously achieve a simple, efficient, and / or user-friendly implementation of the CMV. In this case, the creation of the VolumeDAO can proceed analogously to the previously described creation of a VolumeDAO upon the first upload of digital content. In particular, no uploading / provision of digital content is necessary for registration as a follower.In particular, registration as a follower can be done from outside the segment. In particular, to check whether a VolumeDAO assigned to one of the segments and based on the DLT already exists, the DLT address assigned to the segment can be searched for smart contracts linked to it. If one or more smart contracts already exist that are assigned to the DLT address assigned to the segment, it can then be determined, e.g., by analyzing the publicly accessible code of the smart contracts, whether these smart contracts belong to a DAO, in particular a VolumeDAO, or whether they perform other tasks.

[0022] Furthermore, it is proposed that, upon proof of a follower of the segment's presence at a location in real space that is superimposed on this segment in virtual space, a follower non-fungible token (FollowerNFT) is generated within the DLT. This token is advantageously sent to a DLT address of the DLT assigned to the follower who has proven their presence within the segment and / or which advantageously forms a, in particular additional, governance token of the VolumeDAO. This can enable particularly advantageous local self-management of the digital content, in particular by users associated with the respective segment (contributors and followers). For example, the contributors and followers can decide which types of digital content should be uploaded and / or consumed in a segment.A self-managed ecosystem of content management systems (CMS) with segment-specific regulations can be advantageously created. This can advantageously achieve a high degree of flexibility and / or user-friendliness. A CMV / CMS that is independent of an overarching control authority, particularly a small-scale one, can be advantageously created, which is particularly resistant to censorship or other external influences. In particular, the FollowerNFT governance tokens can be equivalent to the CreatorNFT governance tokens, particularly with regard to voting power. Alternatively, the participation rights associated with the respective governance tokens in the design of the segment / VolumeDAO can differ. For example, the CreatorNFT governance token could be assigned a different voting power, in particular a higher voting power, than the FollowerNFT governance token.For example, the holders of CreatorNFTs could be assigned powers within the respective VolumeDAO that holders of FollowerNFTs do not possess (e.g., the right to propose votes within the VolumeDAO). It is also conceivable that each segment (in addition to uneditable user-uploaded content) contains editable information, similar to a localized Wikipedia, for example. This editable information can then only be modified, deleted, and / or created by users who hold at least one governance token of the segment's VolumeDAO. Deletions, creations, and / or changes to the editable information can be put to a vote in the VolumeDAO.

[0023] Furthermore, it is proposed that each segment of the virtual space forming the metaverse be assigned a, particularly higher-level, volume non-fungible token (VolumeNFT) of the DLT, which comprises spatial (real) coordinates that define the respective segment and link the respective segment to the real space. This advantageously provides a main metaverse that corresponds one-to-one with the Earth's geosphere. This main metaverse contains smaller metaverses in the form of the segments with the VolumeDAOs. The arrangements of these smaller metaverses within the main metaverse are then advantageously irrevocably linked to the physical level. This advantageously allows for the creation of a location-based content management system.Advantageously, a comprehensive yet lightning-fast search engine can now be provided that allows searching for digital content indexed on NFTs, since each of the metaverses, each of the segments, and / or each of the VolumeDAOs is permanently connected to a real location on Earth via the VolumeNFT. The VolumeNFTs can be assigned to DLT addresses controlled by entities. For example, the VolumeNFTs can be owned by an organization that set up the CMS. For example, the VolumeNFTs can be acquired by third parties. It is conceivable that proof of ownership or authorization of the real-world space associated with the respective segment could be considered when transferring ownership of the associated VolumeNFT. Alternatively, the VolumeNFTs could be assigned to a DLT burn address to which no one has access.In particular, the VolumeNFT contains the real spatial coordinates directly and publicly visible, either as a hash or similar, or in encrypted form. The "superordinate" nature of the VolumeNFT should be understood in particular to mean that the VolumeNFT originates from a higher-level smart contract of the entire metaverse and, in particular, not from one of the smart contracts of the individual VolumeDAOs formed in the segments. In particular, a bijective mapping exists between physical locations and VolumeNFTs.

[0024] If the VolumeNFT does not constitute a Volume DAO governance token, a high degree of decentralization and independence of the CMS / CMV can be advantageously achieved. This advantageously means that the owner of the VolumeNFT has no influence on the content and processes within the associated segment, unless they actively participate in the associated VolumeDAO by owning CreatorNFTs and / or FollowerNFTs of the VolumeDAO, which they can only obtain via the regular method described above. A transfer of ownership of the VolumeNFT has no influence on the VolumeDAO or the digital content managed by the VolumeDAO. This advantageously makes it more difficult for outside influence on local processes, especially since governance tokens for the VolumeDAO are only allocated to entities that have actually been verifiably present on-site at least once.For example, a foreign organization seeking to influence a local VolumeDAO in the United States would have to send a large number of people to the location of the segment and / or acquire a large number of existing CreatorNFTs and / or FollowerNFTs of the local VolumeDAO, particularly from predominantly locally rooted individuals, in order to have sufficient voting power to exert significant influence on the VolumeDAO. Thus, the holders of the VolumeNFTs would not be able to vote on proposals within the VolumeDAO, but they could be the only ones able to introduce new proposals to change the governance of the associated VolumeDAO, which could then be voted on within the VolumeDAO by the holders of the FollowerNFTs and / or CreatorNFTs.

[0025] Alternatively, however, it is also conceivable that the VolumeNFT constitutes a governance token of the VolumeDAO. Furthermore, it is conceivable that when a VolumeNFT belonging to a segment is burned, especially automatically, a new VolumeNFT for the segment or multiple new VolumeNFTs for each sub-volume of the segment are created. This advantageously allows for a high degree of flexibility. Furthermore, it is conceivable that when a digital content is withdrawn from a segment, the associated CreatorNFT is destroyed or loses its voting rights in the VolumeDAO of the segment.

[0026] Furthermore, it is proposed that the respective governance tokens and / or the VolumeNFT be transferable, in particular freely, between DLT addresses of the DLT. This can advantageously achieve properties with regard to versatility, design freedom, and / or user-friendliness. In particular, the governance tokens and / or the VolumeNFT can be traded, preferably freely, on NFT marketplaces. The "freely" transferable or tradable nature of the governance tokens and / or the VolumeNFT should be understood, in particular, to mean that the governance tokens and / or the VolumeNFT can also be transferred to entities that are located outside the segments and / or that have never visited the segment in the real space.

[0027] Additionally, it is conceivable that further NFTs exist that are assignable to the respective VolumeDAOs and which may or may not fulfill the function of a VolumeDAO governance token. For example, there could be a MarketingNFT that regulates authorization to place marketing and / or advertising within a segment. This MarketingNFT would then have no governance token function. Like all NFTs, the MarketingNFT can be burned, redeemed, or transferred, thereby manipulating the underlying advertising rights in the respective segment. Furthermore, there could be an InsuranceNFT, for example, through which an insurer can offer liability insurance for a user who uploads digital content. The InsuranceNFT could then be linked to specific digital content and an insurance policy.The insurer could then, for example, receive a fee (via a smart contract), e.g., 1%, from the revenue generated from the digital content, and in return, assume liability damages that may arise, for example, from potential copyright infringements. A user participating in the VolumeDAO would then have the advantage of being able to easily select this option, and the insurer would not have to review each individual piece of digital content, as it would also benefit from the community guidelines anchored in the VolumeDAO and / or the parent DAO. The insurer would thus have the option to exclude liability for violations of the fundamental values ​​of the VolumeDAO and / or the parent DAO and assume only the remaining risks. The InsuranceNFT does not constitute a VolumeDAO governance token.Furthermore, a content management system (CMS), in particular a location-based, preferably decentralized, content management system, is proposed, at least for managing digital content within the metaverse linked to the distributed ledger technology (DLT), such as a blockchain or a tangle, in particular by means of the content management method, wherein the virtual space defined by the metaverse is divided into a number of segments arranged next to one another and / or one above the other, in particular volume segments, and wherein digital content is assigned to individual segments, and wherein at least one of the segments is assigned a decentralized autonomous organization (VolumeDAO) based on the DLT. This makes it possible to achieve advantageous properties with regard to versatility, design freedom and / or user-friendliness.In particular, the CMS comprises at least one interface device, which can be embodied as an electronic (computer) device and which is preferably equipped with, in particular pre-installed, software intended at least for executing the above-described CMV, in particular for uploading and / or consuming digital content and / or for participating in a VolumeDAO. In particular, the interface device is intended for communication with the DLT. The interface device can be embodied as a smartphone, a tablet, a notebook, or the like. In particular, the interface device is embodied as extensively described in the German patent application with application number 10 2021 112 613.4, which is hereby incorporated in its entirety into the present patent application.

[0028] In particular, the interface device forms a localization device. In particular, the interface device is intended for the geographical localization of spatially positioned digital content. When digital content is detected in an area of ​​a current location of the user of the interface device, it is then suggested and / or offered to the user for retrieval. The determination of the digital content virtually prescribed in the area of ​​the user's location can be carried out by comparing the location / location coordinate currently determined for the user with the respective location coordinates assigned to the digital content within the CMS. The area can be variably defined. Useful area sizes can be represented, for example, by circles with diameters between 0.5 m and 10 m (e.g.0.5 m, 1 m, 1.5 m, 2 m, 2.5 m, 3 m, 4 m, 5 m, 6 m, 7 m, 8 m, 9 m, 10 m) can be formed around the currently determined location of the user. For certain applications, such as city tours, even much larger areas of several 10 m or even 100 m are conceivable. In particular, the area could be formed by the segment in which the user is currently located or by a defined number of areas in the vicinity of the user's current location. If one or more items of digital content are found in the defined area, these can be displayed to the user for selection, e.g. in a dropdown menu on data glasses. Digital content that is displayed to the user for selection can be played by the user at the location where the user is currently located.It is conceivable that the digital content is removed from the selection made available to the user if the user moves away from the location coordinates of the digital content, in particular if the digital content is no longer in the changed area of ​​the user's location. Alternatively, it is conceivable that the user "collects" all digital content that was once in the user's location and that this is then made available to the user for later, possibly time-limited, retrieval. It is also conceivable that the digital content is ranked or displayed in ranked form. For example, the digital content can be displayed sorted depending on user ratings, e.g. a number of "likes" or a number of points awarded by the user. In particular, higher-ranked digital content could be given priority, displayed larger, or specially marked.It is further proposed that the localization device be configured to determine a user's current position via communication with locally located anchor stations, wherein at least one of the anchor stations is configured to locally store digital content with a local reference, in particular redundantly, and to make it available to the locally present user for retrieval, for example via UWB, Bluetooth, WLAN, or the like. This advantageously makes it possible to create a particularly efficient CMS in which transmission bandwidth, indexing effort in the search engine, storage and / or, in particular, energy requirements can be minimized, preferably without reducing user comfort on site. This can also advantageously limit energy requirements, which otherwise increase sharply with the amount of data in centralized structures.In particular, the digital content is stored redundantly in the DLT or remotely from the anchor station in order to minimize the risk of data loss.

[0029] Additionally, a metaverse, particularly of the content management system, is proposed. This metaverse comprises a multitude of sub-metaverses, each formed by a segment of the virtual space defining the metaverse and each decentralized by one of the VolumeDAOs based on distributed ledger technology (DLT), such as a blockchain or a Tangle. Advantageously, a decentralized, three-dimensional knowledge space superimposed on the real world can be created, which can be filled, in particular, with free knowledge created by anyone.

[0030] Furthermore, a computer program product comprising instructions that, when executed by a computer, for example, a smartphone, a tablet, a notebook, or an interface device, cause the computer to execute the steps of the content management method is proposed. In particular, the computer has at least one processor and a memory with the program stored in the memory unit. The content management method according to the invention, the content management system according to the invention, the metaverse according to the invention, and the computer program product according to the invention are not intended to be limited to the application and embodiment described above.In particular, the content management method according to the invention, the content management system according to the invention, the metaverse according to the invention and the computer program product according to the invention can have a number of individual elements, components and units that differs from a number stated herein in order to fulfill a functionality described herein.

[0038] Fig. 1 shows a metaverse 20 of a content management system (CMS 48) according to the invention. The metaverse 20 defines a virtual space 24. The virtual space 24 is superimposed on the real space. The virtual space 24 is designed to span the globe. The virtual space 24 is divided into a plurality of segments 26, 28 arranged next to and above one another. The segments 26, 28 each form volume segments, e.g., cubes. The segments 26, 28 are all identical in size and identical in shape. Several digital content items 10 can each be assigned to the segments 26, 28. The segments 26, 28 are remotely searchable. The digital content 10 assigned to the segments 26, 28 are remotely searchable. The metaverse 20 comprises a plurality of sub-metaverses 38, 40. The sub-metaverses 38, 40 are each formed by a segment 26, 28 of the entire virtual space 24 defining the metaverse 20.Each of the sub-metaverses 38, 40 is managed in a decentralized manner and independently of other sub-metaverses 38, 40 by a Decentralized Autonomous Organization (VolumeDAO 14) based on a distributed ledger technology (DLT 16), such as a blockchain or a Tangle. Each of the segments 26, 28 of the virtual space 24 forming the metaverse 20 is assigned a higher-level volume non-fungible token (VolumeNFT 36) of the DLT 16. The VolumeNFT 36 comprises spatial (real) coordinates that define the respective segment 26, 28 and link the respective segment 26, 28 to the real space. The VolumeNFT 36 does not constitute a governance token of the VolumeDAO 14. The VolumeNFT 36 is freely transferable.

[0039] Fig. 2 shows a very simplified schematic diagram of the CMS 48. The CMS 48 is intended for managing digital content 10. The CMS 48 is intended for managing digital content 10 within the metaverse 20. The CMS 48 is intended for managing digital content 10 within the sub-metaverses 38, 40. The CMS 48 is intended for executing a computer program product that implements a content management method (CMV) described below. The CMS 48 is intended for receiving and outputting the digital content 10 to a user 12. The CMS 48 is designed as a location-based CMS 48. The digital content 10 of the location-based CMS 48 is each linked to location coordinates. The CMS 48 is designed to be decentralized. The management of the digital content 10 of the decentralized CMS 48 is carried out decentrally via the DLT 16.The digital content 10 of the decentralized CMS 48 is received and output in a decentralized manner via the DLT 16. The DLT 16 is designed as a decentralized DLT 16. The DLT 16 is designed as a public DLT 16. Alternatively, the DLT 16 can also be private, at least partially centralized and / or non-public. The DLT 16 is preferably designed as an IOTA™ Tangle. In Fig. 2, however, the DLT 16 is sketched as a blockchain by way of example. The digital content 10 of the decentralized CMS 48 can be stored in a decentralized manner, e.g., on the DLT 16, such as a blockchain or a Tangle. Alternatively, the digital content 10 can also be stored centrally on a server or in a cloud, and only the administration can be carried out in a decentralized manner. The CMS 48 comprises a smart contract 18. The smart contract 18 is set up on the DLT 16. The smart contract 18 belongs to one of the VolumeDAOs 14, which is based on the DLT 16.The smart contract 18 is intended to manage the digital content 10, in particular the recording and output of the digital content 10, within the VolumeDAO 14. The smart contract 18 is intended to control playback authorizations for the digital content 10 within the VolumeDAO 14. The smart contract 18 is intended to control the integration of new digital content 10 into a specific CMS 48 of the VolumeDAO 14. The smart contract 18 has one or more input functions ("write functions"). The smart contract 18 has one or more output functions. The smart contract 18 is assigned a DLT address of the DLT 16. The smart contract 18 can receive DLT transactions. The smart contract 18 can send DLT response transactions to other DLT addresses of the DLT 16. Many smart contracts 18 of many VolumeDAOs 14 can be set up on the DLT 16. The CMS 48 has an interface device 22.The interface device 22 is provided for communication with the DLT 16. The interface device 22 is provided for forming an interface between the DLT 16 and a content playback device 54 of the CMS 48, in particular one that can be assigned to a user 32, and / or a content creation device 52 that can be assigned to another user 12. In principle, it would also be conceivable for the content playback devices 54 and / or the content creation devices 52 to communicate directly and independently of the interface devices 22 with the DLT 16. The interface device 22 is permanently assigned to a user 12, 32. The interface device 22 can be designed, for example, as an electronic tag or as a wearable. The interface device 22 is intended to be carried by the user 12, 32. The CMS 48 has a localization device 50. The localization device 50 is intended to determine a current position of the user 12, 32.The localization device 50 is provided for determining the location coordinates where the user 12, 32 is located. The localization device 50 is identical to the interface device 22. Alternatively, however, a separate design is also conceivable. For example, the interface device 22 could receive user locations from a third-party device, e.g., from a smartphone assigned to the user 12, 32. The interface device 22 is provided for comparing the determined locations of the user 12, 32, particularly in real time, with virtual locations of digital content 10 within the CMS 48. The digital content 10 can be designed as augmented reality objects or as virtual reality objects. The interface device 22 is provided for directing the user 12, 32 to digital content 10 that is located within a range of the user 12, 32's location, e.g.,in a segment 26, 28 in which the user 12, 32 is currently located. Alternatively or additionally, the content playback devices 54 can also be provided for this task. The CMS 48 has the content playback device 52. The content playback device 52 is designed differently from the localization device 50. The content playback device 52 is designed differently from the interface device 22. The content playback device 52 is designed, for example, as headphones / VR glasses. The content playback device 52 is provided for outputting the digital content 10 to the user 12, 32. The localization device 50 can be provided to communicate with one or more anchor stations 82. This communication serves primarily to localize the current position of the user 12, 32, but can also be used for the local transmission of digital content 10.In this case, the anchor station 82 is intended to store digital content 10 locally, redundantly to the DLT 16 or as part of the DLT 16.

[0040] The CMS 48 includes the content creation device 52. The content creation device 52 is configured differently from the localization device 50. The content creation device 52 is configured differently from the interface device 22. The content creation device 52 can be configured identically to the interface device 22. The content creation device 52 can be identical to the content playback device 54. In the exemplary illustration of Fig. 2, however, the content creation device 52 and the content playback device 54 are configured differently and separately from one another and, in particular, are assigned to different users 12, 32.

[0041] Fig. 3 schematically shows part of a flow diagram of the CMV. The CMV is designed as a location-based, decentralized CMV. The CMV is intended for managing digital content 10 within the metaverse 20 linked to a DLT 16. The digital content 10 is assigned to individual segments 26, 28 in the CMV. In the CMV, at least the segments 26, 28 to which digital content 10 is assigned are each assigned VolumeDAOs 14 mounted on the DLT 16. The VolumeDAOs 14 of the individual segments 26, 28 are each autonomous and independent of one another. In at least one method step 42, the user 12 enters one of the segments 26, 28. In doing so, they move in the real space. In at least one further method step 44, the geographical position of the user 12 is determined and / or confirmed. The geographical position of the user 12 is determined via the localization device 50.If the user's 12 presence in the segment 26, 28 is reliably confirmed, the user 12 receives permission, in a further method step 46, to upload a piece of digital content 10, which is then to be assigned to the segment 26, 28. In at least one method step 56, the user 12 uploads the digital content 10. The user 12 can place the digital content 10 anywhere within the segment 26, 28. In at least one further method step 58, the digital content 10 newly uploaded to / from the segment 26, 28 is received by the DLT 16, or information that a piece of digital content 10 has been uploaded to / from the segment 26, 28 is received by the DLT 16.In method step 58, upon receipt of the uploaded digital content 10, the digital content 10 is assigned to the respective segment 26, 28 in the virtual space 24 by recourse to the localization of the user 12 initiating the upload, carried out in method step 44, in the real existing space overlaid by the virtual space 24.

[0042] In at least one further method step 60, in response to the upload of the digital content 10 from the segment 26, 28, a Creator Non-Fungible Token (CreatorNFT 30) is generated within the DLT 16. In the method step 60, the digital content 10 is linked to the CreatorNFT 30 on the DLT 16. The CreatorNFT 30 is thus only mined by users 12 who have visited the segment 26, 28 in the real space. However, the CreatorNFT 30 is still freely transferable. In at least one further method step 62, a check is performed to determine whether a VolumeDAO 14 assigned to the segment 26, 28 and placed on the DLT 16 already exists. In the method step 62, a check is performed to determine whether a CreatorNFT 30 (or a FollowerNFT 34, see Fig. 4) already exists for the segment 26, 28.In at least one method step 64, a new VolumeDAO 14 is created for the segment 26, 28 within the DLT 16 if the check from method step 62 shows that no VolumeDAO 14 assigned to the segment 26, 28 yet exists or that no CreatorNFT 30 (or FollowerNFT 34) assigned to the segment 26, 28 yet exists. In at least one further method step 76, the created CreatorNFT 30 is sent to a DLT address of the DLT 16, which is assigned to the user 12 who uploaded the respective digital content 10. The CreatorNFT 30 forms a governance token of the VolumeDAO 14. In subsequent process steps, a further CreatorNFT 30' can then be generated within the DLT 16 for each additional digital content 10' uploaded within the segment 26, 28, which is linked to the respective additional digital content 10' and which also forms a governance token of the VolumeDAO 14.

[0043] Fig. 4 schematically shows another part of the flow diagram of the CMV. The sequence of the method steps with the reference numerals 42' and 44' is similar to the method steps with the reference numerals 42 and 44 already explained in connection with Fig. 3, wherein the user 32 now does not intend to upload a piece of digital content 10, but merely to follow a segment 26, 28 / a sub-metaverse 38, 40 as a follower. If the location of the user 32 in the segment 26, 28 is reliably confirmed, a follower status of the user 32 with regard to the segment 26, 28 in which the user 32 is currently located is determined in a further method step 66. In this case, it is determined whether the user 32 is already following the segment 26, 28 or not. The subsequent status can be changed by the user 32 regardless of location for each of the segments 26, 28 of the metaverse 20.If it is determined in method step 66 that user 32 is not yet following segment 26, 28, user 32 is asked in at least one further method step 78 whether he / she wishes to become a follower of segment 26, 28. If user 32 confirms this, registration of user 32 as a follower of segment 26, 28 is initiated. In at least one method step 68, the registration of the new follower for segment 26 is received in CMS 48. Through the registration, user 32 is assigned to segment 26, 28 as a follower. In at least one further method step 70, a follower non-fungible token (FollowerNFT 34) is generated within the DLT 16, assuming positive proof of the location of the follower of the segment 26 at a location in the real space which is superimposed on this segment 26, 28 in the virtual space 24.The FollowerNFT 34 is thus only mined by users 32 who have visited segments 26 and 28 in the real space. However, the FollowerNFT 34 is still freely transferable.

[0044] In at least one further method step 72, a check is performed to determine whether a VolumeDAO 14 assigned to the segment 26, 28 and placed on the DLT 16 already exists. In method step 72, a check is performed to determine whether a FollowerNFT 34 or a CreatorNFT 30 already exists for the segment 26, 28. In at least one method step 74, a new VolumeDAO 14 is created for the segment 26, 28 within the DLT 16 if the check from method step 72 reveals that no VolumeDAO 14 assigned to the segment 26, 28 yet exists or that no FollowerNFT 34 (or CreatorNFT 30) assigned to the segment 26, 28 yet exists. In at least one further method step 80, the created FollowerNFT 34 is sent to a DLT address of the DLT 16, which is assigned to the user 32 who has verified their presence within the segment 26, 28. The FollowerNFT 34 forms another governance token of the VolumeDAO 14.In subsequent process steps, for each new follower who has proven his or her presence in the segment 26, 28, another FollowerNFT 34' is generated within the DLT 16, which is sent with the respective new follower and which also forms a governance token of the VolumeDAO 14.
