The Sparrow Wallet, an open source Bitcoin wallet that focuses on self-sovereignty and usability, has added support for the implementation of Vortex CoinJoin in its new release. Sparrow 1.5.0 allows users to mix unnecessary transaction output (UTXO) through new integrations into the MainNet and TestNet bitcoin networks.
Vortex is a Chaumian CoinJoin implementation created by the developers of Samourai Wallet. Like other implementations, it allows Bitcoin users to enjoy far-reaching privacy, breaking blockchain observers ’assumptions about their currency and ownership.
In its core part, a CoinJoin is a bitcoin transaction, albeit a special one, where different people unfaithfully combine their inputs into the same transaction, subsequently accepting their responsible output. It seeks to break the heuristics of transactions in which chain analysis companies use cluster addresses together in the hope of breaking the pseudonym provided by Bitcoin.
Through the implementation of the vortex, Sparrow extends that CoinJoin implementation to more users thus helping to increase liquidity in the protocol and, on a larger scale, improve the fungus of all bitcoins. Fungibility is a central aspect of money that prevents two currencies or UTXOs in Bitcoin from being separated or preferred over each other.
Sparrow’s new release allows users to send their CoinJoin output to an external, open wallet after a configurable number of mixing rounds, for example, a cold storage wallet and the option to optimize transactions for privacy (including Stonewall) or skills. Additionally, Desktop Wallet now provides better UX for easy privacy analysis of a scheduled transaction and its tor integration before sending.
As a censorship-resistant technology, ensuring the privacy of users of the currency fungus and the bitcoin network is paramount to prevent coercion and protect personal freedom. Where for centuries omnipotent governments have been able to impose arbitrary rules because of their control over people’s money, Bitcoin has given people the power to fight for human rights causes and defend personal freedoms.
