Arthur Hayes, the former CEO of BitMEX and current chief investment officer of Maelstrom, has expressed his support for the development of Payjoin, a privacy-focused transaction method for Bitcoin. Maelstrom, a family office fund under Hayes, has awarded a $100,000 grant to Bitcoin developer Ben Allen to improve Payjoin. The grant will be paid monthly over the course of a year, with no concrete milestones or strict management, allowing Allen the freedom to work on what he wishes.

Payjoin, first proposed by Nicolas Dorier in 2019, allows both senders and receivers to contribute inputs to a transaction, enhancing privacy and improving the consolidation of transaction outputs. This benefits scalability and makes it more difficult for financial surveillance companies to track Bitcoin transactions. Hayes emphasized the importance of improving financial privacy in Bitcoin, stating that even a small amount of Payjoin adoption could break a key assumption used by financial surveillance companies.

Allen will be working on improving Payjoin implementations, with the goal of making it possible for the feature to be added to more wallets. He plans to build out benchmarks to help downstream developers implement Payjoin in individual wallet software and expand test coverage to ensure consistent and reproducible code. Allen believes that encouraging Payjoin adoption is the biggest step towards simplifying the experience and encouraging its use by moving the complexities mostly away from the user.

Maelstrom is keen to support more grantees in the privacy area and is actively seeking candidates with strong track records in Bitcoin privacy projects. A key metric for Payjoin success would be its adoption by popular open-source Bitcoin wallets, with the BitcoinCore wallet being a significant signal of success. Hayes noted that Payjoin adoption improves the privacy of even those who do not use it, highlighting the broader benefits of the technology.

Even though few challenge bitcoin’s independence and security, privacy has become a major concern. Bitcoin does allow transparency, and all transactions are recorded in a public log. This means one could gain knowledge of your activity and finances. The amount of privacy users’ data receives is often insufficient for some people. This is often for those wanting to safeguard their money from rivals or complete deals in regions where this is not allowed.

With Payjoin, the actual transactions of parties in a Bitcoin agreement are hidden from those outside the transaction using a collaborative approach. While conventional Bitcoin payments show who is involved in every transaction, Payjoin covers both the sender and receiver. This makes it much more challenging for anyone outside to trace the movement of money. It is useful because it helps maintain privacy and also decreases fees by lessening the number of pointless transactions on the blockchain.

A growing number of people in the crypto field now realize the value of having robust privacy measures. As more people around the world use Bitcoin, it will be important to preserve the privacy of each transaction to ensure users’ rights and make the asset more useful.

Under Arthur Hayes’ leadership, Maelstrom Fund has historically backed developments that advance blockchain technology. The fund is supporting Ben Allen’s work on Payjoin, which can provide critical benefits to many people.

Projects such as Payjoin rely on people working closely and openly together. With grants like these, developers are able to work hard on improving their work without being affected by profits. In Hayes’s opinion, providing resources to independent developers leads to faster advancements and keeps all Bitcoin tools open to everyone.

With more regulatory oversight of privacy coins and technologies, support for Payjoin is very useful now. Bitcoin users could enjoy a standard for transactions that blends clear financial information with proper privacy.
