Will Blockchain replace cloud?
The blockchain is another. In fact, just as the cloud displaced legacy enterprise applications, decentralized ledgers will soon replace centralized cloud-based systems. One reason is decentralized ledgers are simply technologically superior to centralized ones.
How is data stored on 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.
Does Blockchain need Server?
Based on a peer-to-peer (P2P) topology, blockchain is a distributed ledger technology (DLT) that allows data to be stored globally on thousands of servers – while letting anyone on the network see everyone else’s entries in near real-time. That makes it difficult for one user to gain control of, or game, the network.
