An example operation may include one or more of receiving a request for blockchain information from a user device, acquiring blockchain data from a plurality of blockchains which are actively operating and available for joining, determining an amount of trust for each blockchain among the plurality of blockchains based on acquired blockchain data of the respective blockchain, and outputting a list identifying the plurality of blockchains where each blockchain on the list comprises a trust indicator indicating a determined amount of trust for the respective blockchain.

On-chain governance of blockchain

An example operation may include one or more of generating a data block for a hash-linked chain of blocks stored on a distributed ledger and accessible to a plurality of computing nodes of a blockchain network, storing governance policies within the data block, the governance polices governing interaction with the hash-linked chain of blocks, and transmitting the generated data block with the encoded governance policies therein to a plurality of peer nodes of the distributed ledger.

An example operation may include one or more of receiving a request to commit a blockchain request to a hash-linked chain of blocks stored on a distributed ledger, extracting governance policies which are encoded within a data block of the hash-linked chain of blocks on the distributed ledger, determining if the blockchain request satisfies the extracted governance policies of the hash-linked chain of blocks on the distributed ledger, and in response to the blockchain request satisfying the extracted governance policies, executing the blockchain request and storing the executed blockchain request within another data block of the hash-linked chain of data blocks on the distributed ledger.

An example operation may include one or more of receiving a request to modify a governance policy of a blockchain, identifying a principal identity that controls the governance policy, determining an allowable combination of signatures of the principal identity required for modifying the governance policy based on a graph data structure storing signature policies for endorsing modifications to governance policies, and modifying the governance policy of the blockchain based on the request in response to an allowable combination of signatures being received.

An example operation may include one or more of receiving a request to implement a modification to previously established governance policies of a blockchain, identifying one or more requirements for the modification based on the blockchain, determining whether the one or more identified requirements are satisfied based on signature data included within the request, and in response to the signature data satisfying the one or more requirements, transmitting the modification to an ordering node for inclusion within a data block of a hash-linked chain of blocks of the blockchain.
