In our previous article, we explored the evolutionary transition of DeFiChain – from UTXO to MetaChain. Now, in this follow-up piece, we delve into the architecture of MetaChain and its incorporation of the EVM layer. Ready to uncover DeFiChain's killer features and how they're shaking up the crypto-verse? Let's get this show on the road! An Architectural Change: EVM Support The imminent introduction of the Ethereum Virtual Machine (EVM) layer will significantly change DeFiChain's architecture. By incorporating a unique transaction type called xVM, DeFiChain effectively integrates EVM transactions without compromising the UTXO model’s security features. Drawing inspiration from Bitcoin's coinbase transaction concept, the xVM transaction features zero input and output and contains the EVM transaction data. This means that the EVM subsystem can authenticate EVM transactions without any understanding of UTXOs required. This innovation guarantees smooth compatibility wi...

The world of decentralized finance (DeFi) is rapidly growing, with numerous platforms emerging to cater to the increased demand for secure, transparent, and easily accessible financial services. DeFiChain is one such platform. Starting out as a Bitcoin fork that utilizes elements from both Bitcoin's UTXO and Ethereum's account models, DeFiChain is transitioning into an innovative ecosystem where an Ethereum Virtual Machine (EVM) layer is built right into the native chain. The culmination of this evolution is Meta Chain – a groundbreaking new concept in the crypto space. In this article, we delve into the existing architecture of DeFiChain and explore its evolution into a universal data layer that promotes interoperability between various blockchains. What is Bitcoin’s UTXO model? UTXO (Unspent Transaction Output) is a virtual representation of cash, serving as a core component of Bitcoin transactions. As Bitcoin’s value is modeled after physical cash, UTXO is necessary to facil...
