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.
Read moreWhat data structure does blockchain use?
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 moreHow data is written to a blockchain model?
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 do I save a file in blockchain?
There are two methods of storing data via blockchain with On-chain and Off-chain . As the name suggests, all the data is stored inside each block on the chain in an on-chain way. Thus, if an attack happens, data can be restored and used.
Read moreCan I store a document on blockchain?

Read moreHow do I upload a document to blockchain?
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.
