Blockchains are write-only data structures with no adminis- trative permissions for editing or deleting of the data . The data structures are known as blocks and are distributed in a P2P network. Each block contains the cryptographic hash function of the previous block and is used to develop a link between them.
Read moreHow is data stored on a blockchain?
Blockchain does not store any of its information in a central location . Instead, the blockchain is copied and spread across a network of computers. Whenever a new block is added to the blockchain, every computer on the network updates its blockchain to reflect the change.

Merkle Trees . Each block in the bitcoin blockchain contains a summary of all the transactions in the block, using a merkle tree. A merkle tree, also known as a binary hash tree, is a data structure used for efficiently summarizing and verifying the integrity of large sets of data.
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 moreWhat type of database does blockchain use?
A blockchain is a digital ledger that stores data in blocks. These blocks are decentralized and broadcast across all nodes in the network. A traditional database, whether an RDMS or NoSQL databases, is also used to store data. … Blockchain vs. traditional database.
