What is XDC Subnet?

A digital realm tailored to your needs

XDC Subnet is a technology that allows you to create a secure, scalable, and decentralized network within the XDC Ecosystem.

It enables various use cases, including creating private subnets, deploying decentralized applications (dApps), and more, so you can keep application transactions inside your own permissioned environment.

Subnets inherit trust from a Validator and Partner Network already run by leading Infrastructure Operators and Trusted Institutions.

Key features

Privacy, control, security and scale by design

Each subnet runs with its own validators, governance, and access controls, configured to your requirements.

  • 01

    Privacy

    Configure your subnets to be private sanctuaries, granting access only to authorized users. Your data and transactions remain shielded from prying eyes.

  • 02

    Sovereignty

    XDC Subnet places the power firmly in your hands, ensuring complete control over your data and transactions. Your network, your rules.

  • 03

    Security

    Fortified by the robust consensus mechanism of the XDC Network, offering resilience to attacks and ensuring the integrity of your network.

  • 04

    Scalability

    Whether you're a small business or a large enterprise, tailor your subnet to grow alongside your ambitions and your application's requirements.

Architecture

Owned by you, anchored to the Mainnet

The architecture consists of the following key components owned by the customer:

  1. 01A subnet driven by the XDC2.0 consensus engine, with system configurations tailored for the customer
  2. 02A relayer program that checkpoints critical consensus data of the subnet to the XDC Mainnet
  3. 03A smart contract in the XDC Mainnet that verifies and records the checkpoints
  4. 04Wallet APIs that enable additional protection of subnet transactions from the XDC Mainnet
  5. 05Native support for XDC utility tools such as blockchain explorer and forensic monitor

Interoperability and Mainnet checkpointing

Private transactions, public integrity

An XDC Subnet can operate with its own validators, governance, and access controls while keeping application transactions within its permissioned environment.

The proposed XIM research extends this approach to heterogeneous blockchains, institutional ledgers, and authenticated financial gateways.

  • Mainnet checkpoints

    A relayer periodically submits subnet consensus data to a checkpoint contract on XDC Mainnet.

  • Private by default

    A public record for integrity checks is created without publishing the underlying private transactions.

  • XDC Zero messaging

    XDC Zero supports communication between a subnet and XDC Mainnet.

  • Endpoints, relayers, oracles

    Endpoint contracts send and receive cross-chain messages, a relayer carries payloads, and an oracle supplies block-header data.

FAQ

Questions about privacy networks

Yes. Subnets can be configured as private networks that grant access only to authorized users. Application transactions stay within the permissioned environment.

A relayer periodically submits subnet consensus data to a checkpoint contract on XDC Mainnet. This creates a public record for integrity checks without publishing the underlying private transactions.

You do. The subnet, relayer, checkpoint smart contract, and wallet APIs are owned by the customer, with validators, governance, and access controls defined by you.

The subnet is driven by the XDC2.0 consensus engine, and its checkpoints are verified and recorded by a smart contract on the XDC Mainnet.

Yes. XDC Zero supports communication between a subnet and XDC Mainnet, and the proposed XIM research extends this to heterogeneous blockchains, institutional ledgers, and financial gateways.
