What is a DAG Structure?

DAG stands for Directed Acyclic Graph—a blockchain alternative that organizes transactions like a web, not a chain.

Instead of blocks lined up one after another, a DAG allows transactions to be processed in parallel, speeding up the network and eliminating bottlenecks.

Key Features

  • No Blocks, No Miners — Every transaction confirms one or more previous ones—no need to wait for a new block to be mined.
  • High Throughput — Transactions are validated simultaneously, not sequentially—perfect for scaling to thousands per second.
  • Lightweight & Efficient — No heavy mining or staking required. Even low-power devices can validate transactions.
  • No Forks — DAGs avoid the risk of chain splits or reorgs, ensuring consistent and stable transaction history.

How It Works (Simplified)

  1. You send a transaction.
  2. Your transaction references and confirms two previous ones.
  3. Others build on top of yours, and the network grows organically—like a graph, not a chain.

Over time, the network self-validates, and consensus emerges naturally.

Why it matters in Xcoin

  • Enables instant, parallel validation
  • Powers zk-Rollups and low-fee transactions
  • Makes the network faster, greener, and more scalable

Why it's safer than a blockchain

In traditional blockchains, transactions are packed into blocks — and those blocks are linked in a single line. That line can be broken. If two blocks are mined at the same time, the network must choose one and discard the other. This can lead to reorgs, where recent transactions are reversed or replaced — opening the door to fraud and double-spending.

Xcoin’s DAG structure avoids all of that.

There are no blocks. No chain. No forks.

Each transaction in Xcoin confirms previous ones directly. The more confirmations it gets, the more permanent it becomes — not because it sits in some lucky “longest chain,” but because it's part of a growing, decentralized graph that can’t be rewritten.

There’s no way to build a parallel history. No way to “win” by creating a longer fork. And no need to wait for 6 confirmations before trusting a payment.

Once your transaction is in the DAG, and others build on top of it, it’s final. Irreversible. Immutable by design.

Xcoin uses a DAG structure to remove the limits of traditional blockchains—
no miners, no blocks, no delays. Just fast, unstoppable private payments.
