DOMAIN NAME REGISTRY SYSTEM WITH ON-CHAIN ASSET-BASED OWNERSHIP AND CONTROL

Resumen de: US2025278723A1

A nameserver receives a request from a user to register a domain name with a domain registrar blockchain that stores domain name registration data in smart contracts. The nameserver performs an off-chain registration process for the domain name with an off-chain domain registrar, including verifying and reserving the domain name. The nameserver then sends a blockchain transaction to the domain registrar blockchain to perform an on-chain registration process for the domain name, the blockchain transaction including the domain name and a digital wallet address for a digital wallet associated with the user. An on-chain asset for the domain name is then minted to the digital wallet, where minting the on-chain asset to the first digital wallet associated with the first user grants exclusive administrative control over the domain name to the first digital wallet.

SYSTEMS AND METHODS FOR AN AI-DRIVEN BLOCKCHAIN PROTOCOL COORDINATING INCENTIVIZED, RISK-AWARE AUTONOMOUS OPERATIONAL AGENTS FOR DYNAMIC RISK/RETURN MANAGEMENT OF TOKENIZED ASSETS

Resumen de: US2025278728A1

An AI-driven blockchain protocol provides systems/methods for managing tokenized assets via autonomous operational Risk-Aware Agents (RAAs). Distinct from prior art automating simple events, the protocol actively coordinates, incentivizes, and manages the RAAs' on-chain lifecycle and operational/financial performance metrics using an Agent Coordination Contract/Module. Verifiable on-chain incentives link RAA operational performance, tracked by said metrics, to risk/return outcomes, thereby underwriting operational execution. An AI engine analyzes aggregated data including RAA metrics, recommending adjustments to RAA incentives and/or metric targets managed by the protocol. RAAs execute operations driven by these incentives, using a protocol-native stablecoin for reward/penalty settlement. A continuous feedback loop enables optimization. This verifiable autonomous operational management provides a foundation for stablecoin-based leverage against the assets, addressing illiquidity. The system comprises interconnected contracts, processor, engine, and RAAs under protocol governance.

SMART CONTRACT, SERVICE CONTROLLED BY VOICE COMMANDS, AND USER DEVICE

Resumen de: WO2025180985A1

The present disclosure proposes a concept where a smart contract receives a transaction related to at least one voice command from a user device.
