In a centralized network, only known and identified parties can transact on the ledger.
What type of technology is Blockchain?
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.
Is Blockchain a network?
A blockchain network is a technical infrastructure that provides ledger and smart contract (chaincode) services to applications. … The users of applications might be end users using client applications or blockchain network administrators.
Can the Blockchain be hacked?
