What makes blockchain unique is the absence of a central authority or a third-party requirement for overseeing transactions. In a blockchain, in order to execute any transaction, which is to be accepted by the rest of the network, the participants of the network need to reach a consensus, which protects the information’s integrity and prevents fraud.

• A distributed ledger is a consensus of replicated, shared, and synchronised
digital data geographically spread across multiple sites, countries, or
institutions. There is no central administrator or centralised data storage
• Peer-to-peer network
• Consensus Algorithms
• Public or Private

CONSENSUS ON A PRIVATE BLOCKCHAIN
• Permissioned network
• Nodes only on invitation
• No complex math problem solving
• Permitted entities sign off on blocks
• Consensus scheme (Raft, Juno)

CONFIDENTIAL
CONSENSUS ON PUBLIC BLOCKCHAIN - PoW (MINING)
• New transactions broadcast to all nodes
• Collect transactions into a block.
• Try to find a proof of work.
• Node finds a proof of work, broadcasts to all nodes
• Receiving nodes validate the new block
• Node that found the block is rewarded

SMART CONTRACTS
• Business logic programmed within a blockchain network
• Help you exchange money, property, shares, or anything of value
• Transparent, conflict-free while avoiding the services of a middleman.
• Saves money, time and is more accurate than manual processing
