DUAL-CHAIN PROPERTY MANAGEMENT SYSTEM FOR THE TOKENIZATION OF ALL THINGS

Resumen de: US2025200682A1

The present invention introduces a dual-chain property management system that integrates blockchain-based tokens with off-chain government and institutional property records to provide secure, verifiable, and legally recognized asset transactions. Unlike existing blockchain-based property solutions, this system prevents unauthorized tokenization, enforces compliance with jurisdictional property laws, and synchronizes title records dynamically. A concurrency management module eliminates double-minting risks, while a discrepancy resolution engine continuously detects and corrects mismatches between blockchain and legal registries. Smart contracts automate ownership transfers, lease agreements, lien tracking, and compliance enforcement, ensuring fraud-resistant transactions in real estate, vehicles, intellectual property, luxury goods, and financial instruments. This innovation enables legally binding digital property transfers with real-time regulatory oversight, bridging the gap between decentralized asset tokenization and traditional legal frameworks. By automating verification, synchronization, and compliance, the system creates a scalable, transparent, and jurisdictionally compliant property management ecosystem.

BLOCKCHAIN-IMPLEMENTED DATABASE OVERLAY, VERIFICATION AND INDEXING SYSTEM

Resumen de: CN119731657A

The embodiment of the invention provides a database covering and indexing mechanism implemented by a block chain. In one embodiment, records in a database are associated with respective unconsumed outputs in one or more transactions on a blockchain by overlay. Each output includes a lock script that specifies which keys can be used to consume the output to other transactions. When a user wishes to access a given record in the database, the other (expending) transactions are generated and sent to a blockchain network. The other transactions include an unlock script that provides one or more keys required to meet the conditions of the lock script, otherwise a consensus mechanism of the blockchain will not allow expenditure of the output and access to the record will be denied. However, if a requirement is met, the output is consumed, and an access request is considered to be authorized. In this way, the consensus mechanism provides an improved authority control and user authorization scheme for a database. When the output is consumed by the other transactions, the overlay is updated to associate the record with the consumed transaction. Transaction logs can also be provided to quickly and efficiently regenerate the database when needed.

Blockchain latency is improved by unclogging a mempool, which frees up electronic memory and reduces CPU usage and network bandwidth. Mining data of one or more initial blocks of a blockchain is accessed. The mining data reveals, for each miner, the time delay between individual transactions mined by that miner.

Thereafter, a different random number is generated for each new block of the blockchain system to be mined. Based on a comparison of this random number and a predefined threshold, either an exploitation phase or an exploration phase is entered for the mining of each new block. In the exploitation phase, mining tasks are assigned only to the subset of the miners. In the exploration phase, mining tasks are assigned to both miners within the subset and miners not in the subset.

AGENT-BASED TURING COMPLETE TRANSACTIONS INTEGRATING FEEDBACK WITHIN A BLOCKCHAIN SYSTEM

Resumen de: EP4568167A2

This invention relates generally to blockchain implementations and is suited for, but not limited to, use with the Bitcoin blockchain. It can be used for the implementation of automated processes such as device/system control, process control, distributed computing and storage and others. The invention provides a solution which uses a blockchain to control a process executing on a computing resource. In a preferred embodiment, the computing resource, running simultaneously and in parallel to the blockchain, manages a loop-based operation. The computing resource continuously monitors the state of the blockchain as well as any other off-blockchain input data or source. The execution of the loop is influenced by the state of the blockchain. Each iteration of the loop that is executed by the computing resource is recorded in a transaction that is written to the blockchain. It is stored as a hash within the transaction's metadata. If the computing resource finds a transaction which contains a hash relating to the loop it accesses the relevant portion of code. The loop contains a conditional statement which enables the computing resource to decide which action to take. The condition may be dependent upon the state of the blockchain or any other data source. The action can be any type of action, on or off the blockchain. Thus, the combination of the computing resource and blockchain provide a solution which is (at least partially) Turing-complete.

METHODS AND DEVICES FOR PROPAGATING BLOCKS IN A BLOCKCHAIN NETWORK

Resumen de: US2025182103A1

Methods and devices for propagating blocks in a blockchain network. At a mining node, while hashing a first block header of a first candidate block, the mining node sends, to other mining nodes, a first message specifying transactions and their order in a first ordered set of transactions contained in the first candidate block. The mining also receives a second message specifying transactions and their order in a second ordered set of transactions contained in a second candidate block being mined by a second mining node. If the mining node succeeds in mining the candidate block it notifies other mining nodes by providing them with a coinbase transaction, hash value, and timestamp. If another mining node is successful, then the mining node receives information from the other mining node from which, in conjunction with the second message, it can assemble the second candidate block and validate it.

UNIFIED IDENTITY REGISTRY

Resumen de: US2025182094A1

Techniques for generation of a unified identity registry are described that support integration and analysis of non-blockchain based user data and blockchain-based user data. A processing device, for instance, monitors an interaction between a client device associated with a user and a digital service provided by a digital service provider. Based on the interaction, the processing device determines a non-blockchain based identifier as well as a blockchain based identifier associated with the user and generates an association between the identifiers. The processing device then generates an identity asset that includes the association for inclusion in an identity registry. The processing device performs a variety of analysis as part of maintaining the identity registry, such as generating segments of identity assets and generating rules to govern access and use of the identity assets. The processing device then grants access to the identity registry based on the rules.
