Samourai Wallet has unveiled a beta version of Whirlpool, a CoinJoin service that enhances transaction privacy. The company previously said that Whirlpool would be released to operate on Dojo, a much awaited bitcoin node built to work with the wallet.
This added feature disassociates crypto senders and their recipients, and makes it difficult to track the financial exchange. Samourai, a leading wallet service, is providing an easy-to-adopt layer of financial privacy for mainstream bitcoin users – and is emerging as one of the first companies to provide this technology.
CoinJoin is a process of anonymization that utilizes various privacy-enhancing software tools. First proposed by Gregory Maxwell in 2013, a “Chaumian CoinJoin” integrates Chaum blind signatures that allow the entry and exit of a transaction to be hidden by grouping and scrambling it with a collection of concurrent transactions.
The Whirlpool framework is a fully modular CoinJoin implementation that has been developed through a “heavily modified” fork of the ZeroLink theory, according to the company.
As noted in previous CoinJoin experiments, the challenge in garnering a mass of participants necessary to conduct blind transactions quickly can be difficult. It took several hours for 100 users of the privacy-centric bitcoin app Wasabi Wallet to gather and collectively execute a CoinJoin. To be sure, this transaction may have been the biggest of its kind.
Apart from the human challenge of organizing a CoinJoin, there are also built-in restrictions on the bitcoin network – such as the limit on the amount of data that can be included in a single transaction block – that limit the viability of CoinJoin. Additionally,
