Can somebody explain me why is DAG better then blokchain?
DAG is more decentralized than blockchain.
In blockchains, there are block producers who are centers of power. Only they can add transactions to the ledger (by packaging them into blocks they create) while users can only
create transactions but not add them.
In DAG ledgers, this power belongs to users as users both create and add transactions to the ledger. That is, the power distribution is more decentralized.
My recent article discusses this issue in more detail
