A Directed Acyclic Graph (DAG) is a topological data structure that models dependencies and relationships between objects. A DAG is a data structure to store transactional information in the blockchain. Blocks are linked together linearly, forming a chain. However, each block contains a hash of the previous block, so it is not truly linear. Rather, it creates a kind of tree, with each block having multiple parents.
What is a Directed Acyclic Graph?
Here are the top 10 benefits of DAG over blockchain technology:
What are some challenges that DAGs face?
What are some projects that are using DAGs?
DAGs offer several advantages over traditional blockchains but still face some challenges. Only time will tell if DAGs gain wider adoption in the blockchain space. However, they certainly offer some interesting potential benefits that should not be ignored.
