You store your encrypted document somewhere and then upload a hash (digital fingerprint) of that document to a blockchain . Then later you can prove that your stored document is actually the one whose hash is preserved on the blockchain.
Read moreWhere is data stored in a blockchain?
Blockchain is decentralized and hence there is no central place for it to be stored. That’s why it is stored in computers or systems all across the network . These systems or computers are known as nodes. Each of the nodes has one copy of the blockchain or in other words, the transactions that are done on the network.
Read moreWhat can you store on blockchain?
Using traditional storage mechanisms The only thing we store on the blockchain is the hash of our data . In comparison to our data, the hash is very small so the cost of a transaction is relatively low. The raw data can be stored in any way we want. For example, we could use a relational database or just a file system.5 Tem 2018
Read moreHow is data stored in blockchain?
Blockchain storage is a way of saving data in a decentralized network, which utilizes the unused hard disk space of users across the world to store files . The decentralized infrastructure is an alternative to centralized cloud storage and can solve many problems found in a centralized system.

Blockchain is stored on all the computers running Bitcoin node . There are thousands of computers running full node. Each of these node record every new transaction in the blockchain. All of these nodes run as backup for the blockchain.23 Ara 2015

Is There Any Blockchain Size Limit? In the last two years, the bitcoin blockchain ledger size has grown from 150 GB to 250 GB . That’s almost 50 GB per year. By 2030, we can see the blockchain ledger size cross more than 1 TB easily.16 Eyl 2021
Read moreDoes blockchain take a lot of storage?
Blockchains aren’t efficient for storing large file sizes . Storage of data “on-chain” can be very expensive and isn’t a very scalable or efficient route for data other than core ledger data and related hashes. Costs can rack up per terabyte on the chain per transaction, with fees each time you want to read that data.21 Haz 2021
