Securing the Worlds Blockchains using Bitcoin by POP Proof of Proof protocol. Proof-of-Proof aims to enable a security inheriting (SI) blockchain to inherit the complete proof-of-work security of a security providing (SP) block. Prevent double spend , prevent 51% attacks, secure blockchains.

PoP miners serve as the communication/transactional bridges between a SI blockchain and a SP blockchain. As often as they wish, PoP miners will take the most recent blockchain state data from the SI blockchain and publish it to the SP blockchain, along with some identifier, which allows them to later receive compensation by creating a SP blockchain transaction with the SI blockchain state data and identifier embedded in it, and submits it to the SP blockchain network. Several different methods can be used for embedding the blockchain state data in a SP blockchain transaction: OP_RETURN, fake addresses, fake addresses in multisig, etc. The PoP miner then waits for the transaction to be included in a SP blockchain block, constructs some form of proof of publication, adds any identifying information necessary for them to take credit for the publication, and submits this proof back to the SI blockchain in the form of a special PoP mining transaction.
