What is the DAG/partial order property of Avalanche?
The DAG/partial order property of Avalanche is a feature that allows transactions to be ordered in a way that does not require a global consensus. This means that transactions can be confirmed faster and with lower latency than traditional blockchain systems. The DAG/partial order property also enables higher scalability and throughput, as transactions can be processed in parallel by different nodes in the network.
However, the DAG/partial order property also poses some challenges for integration with exchanges and other platforms that rely on a total ordering of transactions. For example, exchanges need to know the exact order of deposits and withdrawals to avoid double-spending or missing funds. To address this issue, Avalanche has recently linearized its X-Chain, which is the main chain for issuing and transferring assets on the network.
What are the benefits of linearizing the X-Chain?
Linearizing the X-Chain means that transactions on the X-Chain are now ordered in a single sequence, similar to a traditional blockchain. This makes it easier for exchanges and other platforms to integrate with Avalanche and support its native assets. According to Emin Gün Sirer, the founder of Avalanche, “there isn't a single exchange on earth that is set up to deal with partial order”. By linearizing the X-Chain, Avalanche aims to improve its interoperability and adoption in the crypto space.
Another benefit of linearizing the X-Chain is that it simplifies the development and maintenance of the Avalanche consensus code base. As Patrick O'Grady, an engineer at Ava Labs, explained, “Now that the X-Chain is linearized on both Fuji and Mainnet, ~15.5k lines of DAG-related code could be removed from the codebase”. This reduces the complexity and potential bugs of the Avalanche software.
What are the drawbacks of linearizing the X-Chain?
Linearizing the X-Chain also comes with some trade-offs. One of them is that it reduces the performance and scalability advantages of the DAG/partial order property. As Eric Forgy, a developer and supporter of Avalanche, noted, “The DAG/partial order properties provide solely performance”. By switching to a linear order, the X-Chain may lose some of its speed and capacity compared to its previous state.
Another drawback of linearizing the X-Chain is that it removes one of the unique selling points of Avalanche. As Forgy also remarked, “I hope we can bring DAG back. It was a selling point”. The DAG/partial order property was one of the features that distinguished Avalanche from other blockchain systems and attracted many users and developers to its network. By abandoning this feature, Avalanche may lose some of its appeal and innovation.
The Bottom Line
The DAG/partial order property of Avalanche is a feature that allows transactions to be ordered in a way that does not require a global consensus. This enables faster confirmation, lower latency, higher scalability and throughput for transactions on the network. However, this feature also poses some challenges for integration with exchanges and other platforms that rely on a total ordering of transactions. To address this issue, Avalanche has recently linearized its X-Chain, which is the main chain for issuing and transferring assets on the network.

So, what does the future hold for Avalanche and its DAG/partial order property? According to Emin Gün Sirer, the founder of Avalanche, the DAG/partial order property is not gone forever. He tweeted that “we will bring back DAGs in a future release, when we have a better way to handle them”. He also hinted that Avalanche may introduce a new chain that will leverage the DAG/partial order property for specific use cases.
Until then, Avalanche users and developers can enjoy the benefits of linearizing the X-Chain, such as easier integration with exchanges and other platforms, and simpler development and maintenance of the Avalanche software. They can also explore the other features of Avalanche, such as its subnetworks, smart contracts, bridges, and governance. Avalanche is still one of the most innovative and promising blockchain platforms in the crypto space, and it has a lot to offer to its community.
