Combination of the following features:

Trust is an inherent feature of a Blockchain

• Authenticity – Every action is associated with a Private Key

• Immutability – Once committed, transactions cannot be altered

• Transparency – Data is shared across all nodes in the chain

• Consistency – Transactions that cause conflicts get resolved automatically

• Consensus – All data in the chain is the same across all nodes
