Sparrow Wallet, an open-source Bitcoin wallet focused on self-sovereignty and usability, has added support for the Whirlpool CoinJoin implementation in its newest release. Sparrow 1.5.0<\/a> allows users to mix unspent transaction outputs (UTXOs) via the new integration, both on the mainnet and testnet Bitcoin networks.<\/p>\n

Whirlpool<\/a> is a Chaumian CoinJoin implementation built<\/a> by the developers of Samourai Wallet<\/a>. Like other implementations, it allows Bitcoin users to enjoy forward-looking privacy by breaking assumptions blockchain observers may have about their coins and ownership.<\/p>\n

At its core, a CoinJoin<\/a> is a Bitcoin transaction, albeit a special one, in which different people trustlessly combine their inputs into the same transaction, later receiving their dutiful outputs. It seeks to break transaction heuristics<\/a> that chain analysis companies use to cluster addresses together in the hopes of breaking the pseudonymity provided by Bitcoin. <\/p>\n

By implementing Whirlpool, Sparrow<\/a> increases the reach of that CoinJoin implementation into more users hence helping increase liquidity in the protocol and, at large, improve the fungibility of all bitcoin. Fungibility is a central aspect of money that prevents two coins, or UTXOs in Bitcoin, from being distinguished from each other or preferred over one another.<\/p>\n

Sparrow\u2019s new release also allows users to send their CoinJoin outputs to an external, open wallet after a configurable number of mixing rounds, for example, a cold storage wallet, and an option to optimize transactions for privacy (with Stonewall) or efficiency. Additionally, the desktop wallet now provides a simple privacy analysis of a constructed transaction before sending and a better UX for its Tor integration.<\/p>\n

As a censorship-resistant technology, ensuring the fungibility of coins and the privacy of users of the Bitcoin network is paramount to prevent coercion and secure individual liberties<\/a>. Whereas totalitarian governments have for centuries been able to enforce arbitrary rules due to their control over people\u2019s money, Bitcoin provides people with the power<\/a> to fight for human rights causes and protect personal freedom.<\/p>\n","protected":false},"excerpt":{"rendered":"
