Directed Acyclic Graphs (DAGs), used by IOTA (MIOTA), $HBAR
Hedera (HBAR), and Nano (XNO), differ from traditional blockchains like Bitcoin. DAGs replace linear chains with a graph structure, allowing parallel transaction processing, boosting scalability. $IOTA
MIOTA’s Tangle enables feeless, high-speed transfers, ideal for IoT. HBAR’s Hashgraph offers enterprise-grade speed, while XNO prioritizes instant payments. Unlike blockchains, DAGs don’t rely on miners, reducing energy use but risking security if participation is low. Centralization is a concern, as HBAR’s governance involves a council. MIOTA’s coordinator, though temporary, raises trust issues. $XNO
XNO’s lightweight design sacrifices some decentralization. DAGs excel in speed and efficiency but face challenges in proven security compared to blockchains.
