摘要： A processor may segment a media key block into two or more subsets. Each of the two or more subsets may be respectively associated with a particular group of receivers, and each receiver of the particular group of receivers may be in a blockchain network. The processor may receive, from a first receiver, a request for permission to process the media key block. The processor may identify which of the two or more subsets that the first receiver is associated. The processor may provide a media key block value to the first receiver.

摘要： An example operation may include one or more of generating a hashed timelock contract (HTLC) of an asset and storing the HTLC in a storage structure, where the HTLC requires proof of a condition by a receiver within a predetermined amount of time for the receiver to unlock the asset, executing, via a processing device, a sequential computation a predetermined number of steps and generating proof of a computational load based on an output of the serial computation, determining that the condition for the client to unlock the HTLC has expired, and transmitting a request for a refund of the asset which comprises the proof of the computational load as proof of elapsed time to the storage structure.

摘要： An operator for a global total order broadcast domain executing a method to send an operation out of band to nodes of participating parties in a partition, receive a certificate and a signature on the operation for each of the participating parties, generate a single party packet based on the received signatures, generate a random symmetric encryption key, send the random symmetric encryption key to the participating parties, encrypt the single party packet with the random symmetric encryption key, generate a pseudo random string for the partition, and record an operation identifier, the encrypted party packet, and the pseudo random string on the global total order broadcast domain.

摘要： An example operation may include one or more of receiving, via a custodial service, a request to transact with a digital asset owned by a user and temporarily in custody of the custodial service, generating a blockchain transaction comprising an identifier of the digital asset on a blockchain ledger, an identifier of the custodial service, and an identifier of a recipient of the digital asset, signing the blockchain transaction with a key from a trifocal key which proves that the custodial service is authorized to transact with the digital asset on behalf of the user, and storing the signed blockchain transaction on a blockchain ledger.

摘要： An example operation includes one or more of solving, by a scheduler node, integer programming problem of maximizing a sum of organizations' endorsing peers that run chaincodes from a plurality of chaincodes within a consortium, making, by the scheduler node, endorsement policies (EPs) for the chaincodes from the plurality of the chaincodes to be satisfiable at any time, applying administrator's constraint of available endorsing peers to the maximized sum of organizations' endorsing peers, and adding resulting endorsing peers to a maintenance list.

摘要： An example operation may include one or more of encrypting content via an encryption key to generate encrypted content, storing the encrypted content via a distributed ledger, splitting the encrypted encryption key into a set of key shares via a threshold secret sharing scheme, and distributing the set of key shares among a plurality of nodes of a distributed vault, where each key share is distributed with an expiry value that identifies when the respective key share is to be deleted by a node.

摘要： A node in a blockchain network may receive an event initiation for a digital corollary, receive conditional data related to the digital corollary, invoke a smart contract for the digital corollary with instructions to retrieve and run an asset decay smart module, receive an asset decay smart module from an asset decay smart module repository, and process the asset decay smart module with the conditional data to determine an asset decay.

摘要： An example operation may include one or more of retrieving a block hash of a data block stored on a blockchain, randomly determining a subset of peer organizations from a blockchain network of the blockchain to be endorsers based on a value of the block hash, transmitting a blockchain storage request from a client to the randomly determined subset of endorser peer organizations, and collecting simulated responses from the randomly determined subset of endorser peer organizations into a storage request proposal.

摘要： An example operation may include one or more of identifying a new entry, receiving one or more new entry signatures to approve the new entry to, such that the one or more new entry signatures each include a signature of the new entry and hashes of previously signed entries for a common block, verifying the one or more new entry signatures for commit by performing a signature verification of the new entry, determining the common block has more than one entry with a hash signed by a same member, and responsive to the signature check being performed on the new entry and determining the common block has more than one entry with a hash signed by a same member, designating one or more previously received entries as verified for commit without performing a signature verification of the one or more previously received entries.
