Bitcoin Makes a Bridgeless Leap to Cardano and Back in New Demo

BitcoinOS developers have completed a new test showing that Bitcoin (BTC) can move to Cardano without using a traditional bridge. Developers claimed this is the first time such a “bridgeless cross-chain transfer” has been done. 

This method does not rely on risky bridge systems, which have been targets for hackers in the past.

How the Bitcoin and Cardano Swap Happened 

Many believe the Bitcoin network is underused compared to blockchains like Ethereum (ETH) and Solana (SOL), despite recently recording a massive surge in daily addresses. 

BitcoinOS’s smart contract operating system aims to increase the network’s utility by adding more features without changing its decentralized nature. It could help users and developers do more with the network while keeping it secure.

The demo process started by locking 1 BTC on the Bitcoin blockchain and turning it into xBTC, a programmable token backed by real Bitcoin. This new token was then moved to the Cardano network using the Sundial Protocol, which links both blockchains. 

From there, the token passed through Cardano’s on-chain identity service, Handle. After that, xBTC was transferred back to the Bitcoin blockchain, which was burned and converted into regular BTC. 

This entire process happened on-chain and did not use any third-party bridge or custodian. 

BitcoinOS Ditches Bridges for Safer, Hack-Free Transfers

Cross-chain bridges are vulnerable to manipulation by malicious actors. Since 2022, reports show that over $2 billion has been stolen by targeting cross-chain bridges. In the demo, BitcoinOS avoided this risk by using its own zero-knowledge proof technology, BitSNARK. 

This was tested on Bitcoin’s mainnet last year and made available to developers in March. This new demo used this open-sourced system to prove Bitcoin can move freely and securely between chains.

Divided Opinions in the Bitcoin Community

Not everyone supports this new idea. Some people in the Bitcoin community worry that making Bitcoin more programmable could change its core value. They fear it might become like other blockchains, losing its trusted, straightforward design.

However, BitcoinOS believes that Bitcoin can stay secure while gaining more features. This demo is meant to show that users can do more with the Bitcoin network without risking their assets.
