OpenSats Announced Long-Term Support for Calle & William Casarin
"Calle is recognized for his ongoing work with Cashu, a free and open-source Chaumian Ecash protocol that greatly improves user transaction privacy and efficiency. He has also been instrumental in the development and maintenance of the popular mint implementation, Nutshell, and the wallet, which supports offline Ecash transactions," the organization said.
  • The LTS grant will support Calle in improving the Cashu protocol's robustness and performance, including introducing a fee structure to prevent denial of service attacks, implementing a proof of liabilities scheme for auditing mints, and enhancing the "multinut payments" concept.
"Will’s prolific contributions to the Nostr ecosystem, highlighted by his development of Damus, have advanced Bitcoin integration into social networking through pioneering "Zaps," peer-to-peer micropayments between users over the Lightning Network," added OpenSats.
