Consensus based ad-hoc group creation

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.
