Read moreIs blockchain a data structure or database?
The blockchain in itself is a data structure that stores transactions. It is similar to a linked list in that the data is split into containers – the blocks. Each block is connected with its predecessor with a cryptographically secured reference.
Read moreCan blockchain be used as a database?
Blockchains only differ from other database types by the way they store data. While blockchains can be considered a database , a database is typically not a blockchain. Databases generally don’t use signed blocks to store the data.
Read moreHow do I save a document in blockchain?
The most efficient method is to store a document’s hash on-chain while keeping the whole document elsewhere. The document could be stored in a centralized database or on a distributed file storage system. You would put the document through a secure hash algorithm like SHA-256 and then store the hash in a block.
Read moreHow records are kept in a blockchain database?
Blockchain also uses a distributed record-keeping system called a ledger that keeps track of changes to assets within the chain. Unlike a bank or financial accounting system, the ledger isn’t centralized, but is distributed to all the computers in the chain.
Read moreIs database security important for blockchain?
