The Human Rights Foundation (HRF) Bitcoin Development Fund's latest round will award a total of $210,000 to three Bitcoin Core contributors, two Lightning Network wallet teams and an Arabic translator.
"This round of gifts will focus on: Bitcoin core development, making it easier to run nodes and making it harder to Sybil attack nodes, wallet optimization for emerging markets, privacy improvements for Lightning apps, [and] expanding arabic language Bitcoin education and translation," announced HRF Chief Strategy Officer Alex Gladstein.
HRF will award the largest sum to the Bitcoin Core developers Calvin Kim, Dhruv Mehta and Abubakar Nur Khalil –– who will receive $50,000 each.
Kim currently researches ways to scale the Bitcoin base layer with the Utreexo client and has recently shown promising results. With this new grant, Kim will take it a step further and work "towards making Utreexo usable by an end user," he shared on Twitter.
Meanwhile, Mehta will continue working on Bitcoin Core's security, while Khalil will be working on wallet optimization for his home country of Nigeria.
The Lightning Network app ecosystem will receive two grants, each totaling $25,000. According to the announcement, Sphinx Chat, a Lightning wallet and encrypted messaging service that allows for chatting over Lightning, will use its grant for a new donation interface for humanitarians and activists. And Breez, another Lightning wallet, will dedicate its funding towards bounties to add Tor and NextCloud to its platform and integrate Lightning with Matrix.
Finally, Arabic HODL will use its $10,000 grant to continue translating Bitcoin content into Arabic.
