The blockchain is a distributed network that records digital transactions on a publicly accessible ledger. This paper explores whether blockchain technology provides a suitable platform for the preservation of digital documents. This paper suggests that the hash functions provide a better technique for authentication and storage of documents. Compared to digital certificates, hashing provides better privacy and security. It does not involve the third party for authenticating and the problem of single point storage is eliminated due to distributed nature of blockchain network.
