Bitcoin developer Ben Allen has been awarded a $100,000 grant from Maelstrom, aimed at enhancing Payjoin, a privacy-focused transaction method intended to improve both Bitcoin scalability and user privacy. The grant will allow Allen to work alongside Dan Gould on the Payjoin devkit, which permits both senders and receivers to pool transaction inputs, thereby fostering better privacy and scalability. The project's funding will last for one year, allowing Allen the freedom to work without stringent controls on deliverables. Maelstrom’s chief investment officer, Arthur Hayes, emphasized the significance of improving financial privacy with Payjoin, suggesting that even minimal adoption could undermine assumptions relied upon by financial surveillance entities. Despite challenges, including the need for the receiver to be online and a complex communication flow, Allen aims to make Payjoin readily implementable in various wallets. A key success metric for Payjoin will be its adoption by popular open-source wallets, especially the BitcoinCore wallet.
