Abstract
A block to be added to a hash chain is generated. The block is for a message to be sent and includes a link hash of a prior block previously added to the hash chain. The prior block includes a public key corresponding to a private key to be used to digitally sign the block. The block includes a payload hash of a payload of the message, and a next public key corresponding to a next private key to be used to digitally sign a next block to be added to the hash chain after the block. The next block is for a next message to be sent after the message. The block is digitally signed with the private key and added to the hash chain. The link hash links the block to the prior block in the hash chain. The message is sent.
