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.

Ad-hoc trusted groups on a blockchain

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.

Consensus based ad-hoc group creation

An example operation may include one or more of storing a unique identification code encapsulating encoded information about a trusted group of member devices within a decentralized network, the unique identification code being generated by the trusted group of member devices, decoding the stored unique identification code to generate decoded information which verifies that the user device is a member device of the trusted group of member devices and provides contact information for other member devices of the trusted group of member devices, and establishing a communication session with the trusted group of member devices based on the contact information obtained by decoding the unique identification code.
