Certain aspects of the present disclosure provide techniques for generating digital tokens associated with an asset on a blockchain. An example method generally includes receiving a request to create a digital token corresponding to an asset. A first private key is received. This first private key may be associated with a wallet in which the digital token is to be stored. A second private key is received from a physical device associated with an owner of the asset. An address of the asset is encrypted with a public key associated with the second private key. Metadata associated with the digital token is encrypted with a public key associated with the first private key. The digital token is minted on a blockchain based on the encrypted address of the asset and the encrypted metadata.

Methods and systems are provided for validating secure, consistent, and reliable storage of data, particularly, but not limited to, where storage of the data is delegated to a third party. The data controller Korean obtains at least one sample of its data D on which an operation is performed to produce a variant. Then, her calculates a root value of a Merkel tree representing the data, the data including the changed data samples. In some embodiments, she sends his data to a storage service provider Pobby while retaining shis samples and the generated Merkel root value. The Korean wire does not tell the Pop that she selects which samples, or the operation that she uses in the variant, or any input of the operation. The original copy of the data may be deleted by the Korean. Later, the Borean may require the Paub to perform the same operation on the same data sample, compute and send the root value of the Merkel tree generated to her to verify whether the Paub still has her complete data and the her complete data is in the original state. If the root value of the Paub is matched with the root value of the Kerkel, the Paub must have the original complete copy of the Kerkel data, otherwise, the Paub cannot calculate the correct Merkel root value. Embodiments may be arranged to fully automate the process, including implementation on a blockchain.

Systems and methods for quantifying, tracking, and transacting differential energy attributes (DEA) tokens using a private block chain network. Differentiated energy attributes verified by a 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 multi-signature wallet 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. The systems and methods enable differentiated energy producers to recuperate their DEA related costs and investments via the sale and monetization of DEATs as a value-add to the sale of energy.

The present disclosure provides a security protection method for a sharded blockchain system, and the sharded blockchain system includes one core shard and multiple common shards. A node in the common shard can additionally store historical blocks of other shards in addition to storing historical blocks of the shard in which the node is located. When a single shard in the system is corrupted, the corrupted shard cannot provide a valid verification result for a transaction that the corrupted shard is responsible for verifying. In this case, honest nodes that store historical blocks of the corrupted shard can submit reports on a transaction verification result to the core shard. The core shard confirms validity of the report, and the system performs reward or punishment on the node submitting the report according to whether the report is valid.

Certain aspects of the present disclosure provide techniques and apparatus for efficiently processing transactions on a blockchain. An example method generally includes receiving, at a relay service, a request to execute a transaction on a blockchain. Generally, the request includes a request to transfer a quantity of a first type of token on the blockchain from a transmitter wallet to a receiver wallet identified in the request and incurs a transaction overhead on the blockchain in a second type of token. The request is modified based on the quantity of the first type of token, the transaction overhead in the second type of token, and a policy defining a source from which the transaction overhead is to be retrieved. The transaction is executed on the blockchain based on the modified request without transferring the second type of token from the transmitter wallet to satisfy the transaction overhead.

Resumen de: US2024414387A1
The present disclosure is directed to methods and systems for controlling access to multimedia content. In an access control system, each device operates as a gateway or node in the access control network and is linked to the other devices in the access control network. Each device in the network has a hash value that identifies the device and the type of media content or content providers the device can access. When a device requests to access media content, nodes in the access control system can compare the hash value of the user device to hash values in an allocation table to determine whether the user is authorized access the media content. In some implementations, a device connected to the access control network can verify or validate the hash value of the requesting device by comparing the hash value to hash values in an allocation table stored on a blockchain.
