Blockchain technology is ____________ Distributed Ledger Technology, more commonly known as DLT.
DLT is an approach at ____________ data across multiple data stores, referred to as ledgers.
Blockchain technology ____________ and transmits data in packages which are called "blocks" and are recorded in a distributed ledger.
These "blocks" are ____________ each other via a digital "chain", thus forming a blockchain.
This connection can be ____________, as evidenced by all the blockchain implementations to date.
Permanence within a blockchain is ensured by ____________ that synchronise(s) data across the network in an immutable manner.
Blockchain implementations are technologically categorized into two major types, permissioned and permissionless. The core difference between them is the way ____________.
In a permissioned environment, users are delegated a set of permissions based on a hierarchy that ____________ the operation of the blockchain.
In a permissionless environment, any user can join and participate in the network without any practical requirement distributing the network to the fullest extent. Decentralisation ____________ distribution of the network.
Accounts in a blockchain are identified by their ____________ key which is a part of their cryptographic keypair.
