Technical
Specification
XDC’s EVM-compatible blockchain has the speed, security and the trustless composition to support a series of DeFi applications and enable a future where financial markets can run decentrally, globally, 24/7 with no single central party having any more control or access in this economy than any other.

How is the XDC Network Secured?
XDC Network relies on a delegated proof-of-stake mechanism, titled XinFin Delegated Proof of Stake (XDPoS) to reach consensus. This unique consensus mechanism ensures the XDC Network uses virtually zero energy and is highly resistant to spamming.
A proposed forensics-enabled consensus mechanism (termed XDC 2.0) is built upon an advanced BFT consensus protocol and will guarantee absolute zero forking in the finalized blockchain as long as the ratio of adversarial masternodes in each epoch does not exceed one-third. The block time will be faster with the adoption of XDC 2.0, but, most importantly, after the adoption of XDC 2.0 confirmation is finalization, meaning transactions will be finalized six seconds after their inclusion in a block.
XDC 2.0 builds off of the original XDPoS consensus mechanism by introducing a BFT committee, which is a set of masternodes selected using a deterministic and verifiable algorithm at the beginning of each epoch. The nodes aim to reach consensus using the advanced BFT protocol (Chained Hotstuff) and have the ability to identify malicious actors with cryptographically provable forensic evidence.
In the unlikely event the ratio of adversarial masternodes exceeds one-third during an epoch, those adversarial masternodes will have to sign and certify certain messages that will be embedded into the blockchain in order to violate the safety of the network. These embedded messages can be accessed through on-chain forensics monitoring and used as irrefutable evidence of misbehavior.
The holistic integration of accountability and forensics within the blockchain positions XDC Network as a uniquely secure and well-monitored blockchain protocol.

Token Standards
The XDC community has adopted numerous token standards to ensure the composability of smart contracts and dApps and that the tokens are interoperable across projects built on the XDC Network. The XDC Tokens work with the following standards:
+ XRC20
XRC20 Is the technical standard for fungible tokens and is used for token implementation in the majority of smart contracts on the XDC Network. XRC20 tokens can digitally represent virtually anything and are widely accepted by wallets and exchanges.
+ XRC721
Non-fungible Tokens (NFTs) have gained popularity in the collectables, art, gaming, and music industry to show ownership of unique items. XRC721 is the standard used to build NFTs on the XDC Network and it defines the minimum requirements a smart contract must meet for NFTs to be owned, managed, and traded.
+ XRC1155
XRC1155 is a multi-standard token combining XRC20 and XRC721 standards that allow for multiple tokens to be generated within a single contract. The XRC1155 is a single smart contract that can represent and govern an infinite number of tokens.
The XDC Ecosystem has developed roots across industries. As the technology reaches new markets, opportunities emerge for users to interact and exchange with a diverse selection of network participants.
RWA Tokenization. From long-standing, highly-liquid U.S. Treasuries to previously less accessible trade finance assets, real world assets (RWAs) are growing in tokenized form on the XDC Network. RWAs have become a catalyst for network usage and digital asset adoption throughout all of blockchain technology. They create a gateway and a critical link between traditional finance and blockchain technology.
Trade Finance. XDC has become recognized for its outstanding presence in the trade finance industry. Positioned to serve as distributed ledger connecting a series of trade finance based applications in a manner that supports a robust and decentralized trade ecosystem, XDC Network is a public resource delivering much needed advancements to the industry.
XDC Subnets. XDC Subnets are sovereign blockchains that operate independently of the public XDC Network, receive the public XDC Network’s security protection, and allow organizations to run a production-ready blockchain in their own independent web3 environments.
