Communication Method and Communication Apparatus

Resumen de: US20260180720A1

In a communication method, a first network element sends request information to a second network element deployed in an operator network, where the request information is used to request to perform a first operation on a first smart contract (SC) that the first network element expects to manage. The second network element sends indication information to a first node in a first blockchain (BC) based on the request information, where the indication information indicates to perform the first operation on the first SC, and the first BC is a BC on which the first SC is to be deployed or has been deployed. The first node in the first BC performs the first operation on the first SC in response to the indication information.

Golf ledger and token

Resumen de: GB2644927A

This invention pertains to the fields of distributed ledger, cryptocurrency, and decentralized physical infrastructure network. It solves the problems of the blockchain trilemma and cryptocurrency's lack of a real-world value that is recognizable to the mainstream population. Those two problems have prevented any cryptocurrency from gaining mass adoption. The Golf Ledger is distributed across a network of computers that are installed at up to 40,000 golf courses to leverage the existing decentralization of the world's golf courses and their ownership entry barrier and therefore does not need to sacrifice scalability for decentralization and security. The Golf Token as the native cryptocurrency of the Golf Ledger network is rewarded to golf courses for their contributing more and more computing resources to make the network more scalable. Their customers can use the Golf Token to pay golfing fees and get a discount, which is an obvious real-world value.

METHODS AND SYSTEMS FOR FREEZING DIGITAL ASSETS

Resumen de: EP4765728A2

0001 Systems and computer-implemented methods for freezing or unfreezing digital assets on a blockchain. A freeze administration service may send a signed freeze request to mining nodes, which maintain two blacklists of digital asset identifiers: a pending blacklist and a consensus blacklist. The digital asset identifiers may be transaction outpoints in some cases. If accepted by the mining node, the transaction outpoints in the freeze request are added to the pending blacklist, which causes rejection of any transactions using those outpoints, but does not cause rejection of any new blocks that include transactions using those outpoints. If a consensus threshold of acceptances is reached based on hash power, the request becomes an order and the outpoints are added to the consensus blacklist, which causes rejection of any transaction or block containing a transaction using those outpoints.

BLOCKCHAIN TRANSACTION REBROADCAST

Resumen de: US20260170489A1

Certain aspects of the present disclosure provide techniques for reliable cryptocurrency rebroadcasting. According to certain embodiments, after an initial transaction broadcast disclosed systems listen to a blockchain to determine if the transaction was included in the blockchain. If, after a short time period, the transaction is not confirmed, a transaction database record for the transaction is locked to prevent inadvertent rebroadcast. While the record is locked, the transaction format and replay information are verified, and depending on the blockchain, is updated. For blockchains having a transaction fee, the system reviews recent transactions to determine appropriate fees and if needed, updates the transaction fee accompanying the transaction. Once the replay information is verified/updated, and the transaction fee is sized appropriately, the database record is unlocked and the transaction is rebroadcasted.
