A method, computer system, and a computer program product for blockchain enabled crowdsourcing is provided. The present invention may include receiving an asset from a content provider. The present invention may also include deploying a smart contract based on the received asset, wherein the deployed smart contract includes a plurality of compensation rules. The present invention then may include partitioning the received asset into a plurality of fragments based on the deployed smart contract. The present invention may further include releasing the partitioned plurality of fragments into a blockchain network. The present invention may also include tracking each fragment within the released plurality of fragments using the smart contract.

Blockchain enabled crowdsourcing

An example operation may include one or more of identifying a blockchain transaction, storing the blockchain transaction in a blockchain, assigning the blockchain transaction a transaction number and a block number, hashing a portion of blockchain transaction data associated with the blockchain transaction, and updating a blockchain index based on the hashed portion of the blockchain transaction.

Optimizing queries and other retrieve operations in a blockchain

An example operation may include one or more of connecting, by a clock node, to a blockchain network comprised of a plurality of nodes, retrieving, by the clock node, a timestamp (Ts) of the clock node, acquiring, by the clock node, a time window (Tw) based on the Ts, reading, by the clock node, a current window (Cw) from a world state, determining, by the clock node, a gap as a difference between the Tw and the Cw, calculating, by the clock node, a clock fix value based on the gap, and adjusting a clock by a subtraction of the clock fix value from the Ts.

Distributed clock

One example method of operation may include receiving a request, from an entity, for one or more tokens based on one or more attributes, encrypting and masking the one or more attributes, adding the encrypted and masked one or more attributes to the one or more tokens, and transmitting the one or more tokens to the entity.
