Hathor is a transactional consensus platform comprised of an entirely novel architecture, based on concepts from both directed acyclic graph (DAG) and blockchain technologies combined. They propose a solution to the problems of scalability and decentralization maintenance among distributed ledger networks by including a chain of mined blocks inside a DAG of transactions. The blockchain ensures security when the number of transactions per second is small, whereas the DAG prevails when the number increases significantly. The primary result is that it seems to work correctly under any number of transactions per second.
