Bitcoin Privacy Boost: Ben Allen Secures Maelstrom Grant for Payjoin Enhancement
May 20, 2025
Maelstrom, led by Hayes, is committed to supporting digital asset infrastructure through grants that promote a more private, scalable, and decentralized Bitcoin ecosystem.
As Bitcoin's public ledger transparency raises concerns about user privacy, the need for robust privacy measures has become increasingly critical.
Payjoin, introduced in 2019, allows both senders and receivers to contribute inputs to a transaction, enhancing user anonymity and challenging the notion that multiple inputs must originate from a single entity.
Allen will work with Dan Gould to integrate Payjoin into more Bitcoin wallets, despite the technical challenges such as the requirement for receivers to be online.
Arthur Hayes, Chief Investment Officer of Maelstrom, announced the grant, emphasizing Payjoin's potential to disrupt assumptions held by financial surveillance firms.
Ben Allen has been awarded the Maelstrom Bitcoin Developer Grant to enhance the Payjoin Dev Kit, a project designed to improve privacy and scalability in Bitcoin transactions.
The initiative aims to enhance transactional privacy on the Bitcoin network, which could lead to increased adoption and trading volumes for Bitcoin and privacy-oriented tokens.
Grants like the one for Payjoin enable developers to concentrate on technological improvements without the pressures of profit, fostering collaboration within the crypto space.
As of today, Bitcoin is trading at approximately $67,500, reflecting a 2.3% increase in the past 24 hours, with trading volume spiking by 18% to $32.4 billion.
The announcement of the grant could act as a catalyst for short-term bullish momentum in Bitcoin and related privacy tokens, especially if key resistance levels are surpassed.
Under Hayes' leadership, the Maelstrom Fund has a track record of supporting innovations that advance blockchain technology, exemplified by its backing of Allen's work on Payjoin.
Hayes highlighted the importance of enhancing Bitcoin privacy, empowering users to control their financial data for a better overall experience.
