Cardano-Based Cardinal Protocol Targets Native Bitcoin Access for DeFi

The protocol aims to convert Bitcoin UTXOs (unspent transaction outputs) into Cardano native assets on a one-to-one basis, seeking to bring Bitcoin liquidity into DeFi (blockchain-based financial services) without custodians.

Summary

The Cardinal protocol is designed to bring Bitcoin to Cardano in a native form by wrapping Bitcoin UTXOs (unspent transaction outputs) into Cardano native assets with a one-to-one peg. According to the source, the goal is to unlock Bitcoin liquidity for Cardano’s DeFi (blockchain-based financial services) ecosystem without relying on custodians. If implemented as described, the approach would aim to let Bitcoin holders access decentralized financial activity on Cardano while preserving a direct asset mapping between the original Bitcoin output and its Cardano-based representation.

Terms & Concepts
  • UTXO: A UTXO (unspent transaction output) is a spendable unit of cryptocurrency created by a blockchain transaction, commonly used in Bitcoin’s accounting model.
  • Cardano native assets: Tokens issued directly on Cardano’s blockchain without requiring a separate smart contract (self-executing blockchain code) standard for basic asset creation.
  • Custodian: A custodian is a third party that holds assets on behalf of users; non-custodial designs aim to reduce reliance on centralized control.
