Here's how to avoid destroying the privacy of your bitcoin.

A single bitcoin transaction can destroy years of privacy.

This week, Cake wallet 's chief operating officer and activist Seth For Privacy stated on the Bitcoin Rails podcast that bitcoin privacy is an issue of particular concern to Western users, and warned that a single transaction can link a user's identity with years of digital currency usage history.

Mistakes hidden in the silverware.

Seth explains that the wallet does not store a single block of money, but stores unused lists separately based on past transactions. Each list is like an individual coin; when users submit more than one value for each transaction, it may select multiple entries as inputs to the same transaction. If the user leaves the system unsupervised, the system might not know which items are associated with their identity and which aren't.

He warned that if an unverified coin, or no- KYC , is used alongside a verified coin,[4] in the same transaction, the two pieces of data may be instantly linked, allowing bitcoins not previously associated with identity to become part of a user's identity. This was about managing inventory that hadn't been used yet, or what some wallets called "coin control".[5]

The background of the argument.

The issue of bitcoin's privacy resurfaced after the developer of its coin-mixing tool for privacy, Samourai wallet , was sued last year and subsequently jailed. However, in the same week, the U.S. Treasury Department dropped two longstanding crypto surveillance proposals that privacy advocates and the digital asset industry viewed as a major victory.

Seth compares that in the global South, where people have more experience with oppressive governments, they may be more aware of the value of privacy, and Western users might see a need for it firsthand. He says over the last five or six years, attitudes are starting to change -- even among westerners who think this is important.

Pocket options and secondary networks.

Cake wallet is a privacy-focused wallet that allows the custodian to manage their own assets and is open source. Earlier this year, such wallets included Lightning Network in the platform. The use of secondary or Layer 2 networks like these enables faster transactions, lower costs, and more privacy than Bitcoin's main network.

A view of a particular coin.

Seth noted that if Bitcoin could provide privacy close to Monero without going through the hassle and eliminate the need for digital coins like Monero , he would accept it, because he wanted a platform where more people worked with better privacy qualities rather than having perfected specific tools but few users and limited popularity.

The lesson here is to handle unused lists with care, because a single mistake can erase the privacy that users have accumulated over time. Original content posted on Bitcoin Magazine and written by Mathew Di Salvo
