Abstract:

An example operation may include one or more of sending, by a node A, a signed transaction Tr.sub.A to a node B to update a token TKN.sub.A on a ledger of a blockchain A, submitting, by the node A, the Tr.sub.A signed by the node B to the blockchain A, receiving from the node B a signed transaction Tr.sub.B to create a token TKN.sub.B on a ledger of a blockchain B, sending the Tr.sub.B signed by the node A to the node B to be submitted to the blockchain B, and activating, by the node A, the Tr.sub.A to update the TKN.sub.A by submission of a secret value (x) signed by a private key of the node A to the blockchain A and by submission of a secret value (x) to the blockchain B to activate TKN.sub.B.
