all types of transactions can be stored in blocks on a blockchain.
What kind of data can be stored in 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.
Can all transactions be stored in 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.
