The traceability method comprises the integration of traceability software, blockchain, and physical marking at origin using inert nanomarkers that are visible only when excited by a laser of a specific frequency. This integration ensures immutable and robust information in the process of tracing products and raw materials, as well as their production processes, since the nanomarker is not destroyed. In dielectric products/raw materials, integrity analysis equipment is used which, through readings of the reflection of the electromagnetic waves resulting from the interaction thereof with the material, determines its characteristic and unique dielectric profile - since each product has a dielectric constant for each wave frequency - resulting in a reflection-versus-frequency graph that is characteristic of the material. This profile is linked, by the user owner, in the traceability method, to the code corresponding to that product. The method is capable of managing the geolocation of each action on a product or raw material, generating unique and random two-dimensional alphanumeric codes, recording each action in the chain via smartphones or two-dimensional optical readers, linking these codes to tax documents and nanomarkers, as well as generating reports for decision-making.

A rights bound token (RBT) creation and management engine (C&ME) generates and manages RBTs, in a distributed, immutable, permanent, decentralized, verifiable, secure, permissionless, trustless form and/or evolvable. RBTs constitute a new asset class, and are digitally native, decentralized assets that evidence rights to other assets, employing blockchain technology using distributed ledgers and that are advantageously blockchain agnostic and enhance security. RBTs employ an on chain token and a rights package inextricably bound by at least one external binding. Rights packages are comprised of a rights manifest and a rights storage mechanism, selected from various rights manifests and rights storage mechanisms. Treating the token, rights package (rights manifests, rights storage) and bindings as distinct objects advantageously allows customization for various technical and non-technical criteria, and facilitates operation is across a wide range of different blockchain services, accommodating heterogeneous protocols, heterogeneous file types and even heterogeneous storage mechanisms.

Compressing and re-securing blockchain data using a large codeword model (LCM) with deep learning. The LCM tokenizes the blockchain into sourceblocks, assigns unique codewords to each sourceblock, and processes the codewords through a deep learning core, enabling efficient compression, semantic understanding, and generation of blockchain data. In the event of a compromised block, the system re-encodes and rehashes the entire compressed chain, generating a new secured chain while preserving the original chain as metadata for backward compatibility. The LCM-based approach enhances security, efficiency, and resilience of blockchain networks, offering significant advantages over existing techniques.

Die vorliegende Erfindung betrifft ein Verfahren zum sicheren Entfernen von Blöcken aus einer bestehenden Blockchain in einer abgeschlossenen Infrastruktur wie zum Beispiel einem Firmennetzwerk. Das vorgeschlagene Verfahren schafft den Vorteil, dass Einträge aus der verketteten Liste entfernt werden können, ohne, dass hier die weitere Integrität der Kette gefährdet ist. Blockchains sehen grundsätzlich nicht vor, dass Blöcke aus der Datenstruktur entfernt werden, was durch die redundante Speicherung verhindert wird. Die vorliegende Erfindung überwindet diesen Nachteil und schafft zudem einen Mechanismus, der es erlaubt die Datensätze nachträglich ggf. wieder herzustellen. Die Erfindung ist ferner gerichtet auf eine entsprechend eingerichtete Systemanordnung. Ferner wird ein Computerprogrammprodukt mit Steuerbefehlen vorgeschlagen, welche das vorgeschlagene Verfahren implementieren beziehungsweise die vorgeschlagene Vorrichtung und Anordnung betreiben.

The invention is developed in the field of technology. The invention relates to a system for dynamically authenticating alcoholic beverages, including digital cryptographic mechanisms that allow real-time access to the status of an alcoholic beverage, through the use of blockchain technology. In particular, the system consists of a "quick-response" (QR) code provided on the inside of the lid (liner) or cap or cork or dispenser or device used to close the product and the QR code is only displayed when the product is open, to then be authenticated by the user when they wish to verify the legitimacy and traceability of the product. A cryptoasset (not cryptocurrency) is linked to each QR code, which is backed by the blockchain, and, by reading the unique QR code printed on each cap, the metadata thereof is obtained via the web. Only the first status of the bottle "BOTTLE SAFE FOR CONSUMPTION" is obtained when it is read for the first time, then the second status of the digital asset "BOTTLE PREVIOUSLY OPENED" will always be displayed, making it impossible to return to the first status of the bottle given the immutability and security of the blockchain. This dynamic digital asset can be associated with a type of dynamic NFT, such as a cryptoasset (NOT CRYPTOCURRENCY), and therefore, the system according to the invention constitutes a novel and inventive alternative for the traceability of products by manufacturers and users, in particular in the liquor industry, since it constitut

Systems and methods for quantifying, tracking, and transacting differential energy attributes (DEA) tokens using a private block chain network and a cloud-based application platform. Differentiated energy attributes verified by a third-party verification entity pursuant to emission standards are digitized as differentiated energy attribute tokens (DEATs). A predetermined formula correlates the number of DEATs to be minted to the units of differentiated energy produced. DEATs are published to a differentiated energy producer's modified private blockchain multi-signature wallet (mMSW) governed by the terms and conditions of a smart contract. DEATs may be transacted in a bilateral transaction between a buyer and seller under a transaction smart contract. Smart contracts are executed by one of more authorized signatories using their respective platform managed digital signatures (PMDS) instead of blockchain based public or private keys.
