Abstract: An example operation may include one or more of identifying a group of blockchain member devices attempting to establish a trusted group communication channel, assigning each of the blockchain member devices public/private key pairs, publishing the public keys of the blockchain member devices in a list, identifying a request from a first blockchain member device requesting a private key, associated with a second blockchain member device, be applied to a predetermined nonce value, responsive to identifying a response to the request, verifying, via a public key assigned to the first blockchain member device, that the second blockchain member device is a trusted member of the group of blockchain member devices, and responsive to verifying the second blockchain member device is a trusted member of the group of blockchain member devices, permitting communication between the first blockchain member device and the second blockchain member device on the trusted group communication channel.

Abstract: An example operation may include one or more of: creating a document that defines procedures to create an ad-hoc group having an original peer, to add a new peer to the ad-hoc group and to remove of one or more of the original peer and the new peer; maintaining, via a memory, a cryptographic distributed ledger based on the document and peer data associated with the ad-hoc group; encrypting the document; encrypting the cryptographic distributed ledger; providing the encrypted cryptographic distributed ledger to the ad-hoc group; decrypting the encrypted document; modifying the document; decrypting the encrypted cryptographic distributed ledger; updating the cryptographic distributed ledger; encrypting the modified document to create an encrypted modified document; encrypting the updated cryptographic distributed ledger; and providing the updated encrypted cryptographic distributed ledger to the ad-hoc group.
