XDAG

XDAG is a cryptocurrency built around a DAG structure rather than the classic single-chain layout, so it sits closer to experimental payment tech than to the plain proof-of-work coins most people know. By our assessment, that makes its main appeal architectural: it tries to move transactions in a more parallel way, which is exactly the sort of idea crypto people like to poke at. The downside is also structural, because anything this niche asks a reader to understand the ledger shape before the coin itself makes sense. In practice that usually means a project for people who enjoy the design problem first and the token second, not for anyone who wants a simple store-of-value story. Compared with Bitcoin or even more mainstream payment coins, XDAG feels more like a technical proposal that happens to have a market attached.
