An example operation may include one or more processing transactions of a plurality of blocks of a blockchain of the blockchain network to determine a user of a plurality of users that is a party of the respective transaction and a mining pool of one or more mining pools that included the respective transaction in the blockchain, performing a statistical analysis of the transactions to determine if the transactions of a user of the plurality of users is distributed across the one or more mining pools in a statistically expected manner, determining that the user has a special relationship with one or more of the one or more mining pools if the transactions of the user are not distributed across the mining pools in a statistically expected manner, and for a user that is determined to have a special relationship, determining one or more of the mining pools with which the determined user has a special relationship.

Special relationships in a blockchain

An example operation may include one or more of identifying a smart contract, processing the smart contract to create a smart contract definition, determining whether the smart contract has been accepted by identified parties, when the smart contract has been accepted by the identified parties, generating a smart contract definition hash, and forwarding the smart contract definition hash to one or more blockchains.
