By launching Cardinal, Cardano has taken a new step towards filling the gap between Bitcoin and decentralized finances. This protocol allows top blockchain networks to interact with Cardano’s defi ecosystem.
Cardano founder Charles Hoskinson highlighted the release on June 9th and shared a post from Roman Pellerin, chief technology officer of Input Output Global (IOG), the development arm behind Cardano.
The launch of the protocol marks Cardano’s most focused efforts, bringing Bitcoin liquidity to the ecosystem. In doing so, Cardano aims to unlock new opportunities for decentralized finance and provide Bitcoin holders with a safer way to engage in new blockchain applications.
Meanwhile, Pellerin pointed out that despite already wrapping/wrapping the initial order in Bitcoin and Cardano mainnets, it has yet to consider the production response of the protocol. He added:
“The protocol works, but as mentioned in the paper, we don’t think it’s production-ready yet. There are some improvements happening. Stay tuned for the 1.0 version.”
What is Cardano Cardinal Protocol?
Cardinal illustrates a key step in Cardano’s push: providing decentralized access to Defi services such as lending, staking and borrowing without relying on centralized bridges or custodians.
Instead, we introduce a more secure mechanism for wrapping transaction output (UTXOS) without Bitcoin, turning them into free-to-move assets.
Cardinal wraps Bitcoin Utxos and makes it available as a transferable token within Cardano’s Defi Ecosystem. These wrapped tokens use their original Bitcoin counterparts to maintain a strict one-to-one peg. Users can burn the wrapped assets at any time to bring the actual Bitcoin back into the native chain.
The system is built on a trusted minimization model, which assumes that at least one of many operators will work honestly.
Unlike federation models that require a large portion of honest actors, Cardinal maximizes decentralization while minimizing trust. It also implements Musig2, a multi-signature cryptographic protocol that allows multiple entities to collaborate on a single transaction to enhance security.
To address the risk of chain reorganization or delays in cross-chain operations, the cardinal waits for a check of the number of sets before performing any critical steps. This approach reduces vulnerability and enhances the integrity of asset transfers between Cardano and Bitcoin.
Cardinal also utilizes BitVMX, an off-chain computing system that supports advanced Bitcoin operations without compromising decentralization. By integrating with Cardano’s smart contract infrastructure and Bitcoin’s native scripting, BitVMX ensures efficient, secure, and programmable interactions.
