Once a transaction is committed to database, the records cannot be changed because they are linked to every transaction that came before them.
Various computational algorithms are deployed to ensure database commits are permanent, chronological and available to others on the network.
Every transaction is visible to anyone with an access to the network. Each node on a Blockchain has a unique 30-plus-character alphanumeric address that identifies it.
Users can choose to remain anonymous or provide proof of their identity to others. Transactions occur between Blockchain addresses.
Each party on a Blockchain has access to the whole database and its complete history.
No single party regulates information.
Everyone can validate the records of its transaction partners directly, without an intermediary.
