Description
Spinner is a privacy-enhancing service for the Internet Computer (ICP) and Bitcoin (BTC) blockchains. It utilizes zk-SNARK technology to enable private transactions. Users can mint private notes by depositing a corresponding amount of tokens (like ICP) into the Spinner smart contract. These notes can then be used to withdraw funds anonymously at any time. The system maintains a hidden ledger, meaning it does not record user accounts or addresses, ensuring transaction privacy. Thanks to zk-SNARKs, users can prove the existence of a deposit for a withdrawal without revealing any details about the original deposit. Spinner also leverages the Internet Computer's direct integration with Bitcoin, allowing for private transactions directly on the Bitcoin blockchain without the need for bridges.
