Bitcoin And Internet Computer Integration - Bitcoin Gets Smart Contracts

 

The Internet Computer is the only blockchain that supports both smart contracts and the Internet Identity system, which allows users to anonymously authenticate themselves to Web 3.0 dapps and services using any device that implements the WebAuthn standard. This means that a Bitcoin wallet can be created using Internet Computer smart contracts that are directly served from the blockchain into a web browser, allowing users to securely, conveniently, and anonymously authenticate themselves using, for example, the fingerprint sensor on their laptop or face recognition on their phone, in order to send bitcoins.

New cryptography techniques

The DFINITY Foundation's Internet Computer blockchain will use new cryptography techniques to interact with the Bitcoin network, allowing smart contracts to operate directly on bitcoin balances for the first time. DFINITY's related R&D effort will be accomplished after the Internet Computer community approved a Network Nervous System (NNS) proposal with 96.55 percent acceptance on September 17. Since the network's inception in May, it had already received 20,586 proposals.

The Blockchain Computer On The Internet

The Internet Computer is the world's first public blockchain that: Can truly scale to host any volume of smart contracts and related computation and data, making it the first unbounded blockchain Runs at web speed by finalising transactions that update data in 2 seconds and others in milliseconds, making it the world's fastest blockchain



This integration is possible because, utilizing chain key cryptography, the Internet Computer protocol will be able to safely produce the ECDSA signatures used in bitcoin transactions on behalf of smart contracts (after the Taproot Bitcoin upgrade in November, Schnorr signatures will also be created). Meanwhile, Internet Computer Network nodes will consume Bitcoin blocks directly to ensure that smart contracts have access to balance information at all times.
