Abstract
A method for integrating a Proof of Storage (PoS) into a blockchain increases security, robustness and verifiability of a blockchain network. A part of the blockchain to be stored is received at a first one of a plurality of mining nodes of the blockchain network. The part of the blockchain is stored. Mining of the new block is bound to the stored data and performed so as to enforce that the mining nodes store different parts of the blockchain. The PoS is integrated into the new block. The PoS is verified before accepting the new block into the blockchain.
