摘要：
A method for securing a blockchain and incentivizing the storage of blockchain data using a publicly verifiable proof of retrievability (PoR) includes receiving a PoR transaction having a PoR proof; determining whether the PoR proof is a verified PoR proof; and based upon determining that the PoR proof is a verified PoR proof, incorporating, by a block creator node, the PoR transaction into a new block of the blockchain.
