Keith Mukai
Keith Mukai, volunteer lead developer of SeedSigner, reports on the first in-person gathering of the FOSS DIY signing device teams in Sao Paulo, organized by Lucas Ferreira of Vinteum with Human Rights Foundation funding at Vinteum's Casa 21. Stepan Snigirev attended and handed shared custody of the embit library to nominated co-maintainers from Specter DIY, SeedSigner and Krux; CryptoGuide and former Blockstream CTO Lawrence Nahum also took part. Long appended sections explain FOSS/DIY signing devices and profile Specter DIY, SeedSigner and Krux. The piece is a republication of a GitHub article, carried with the magazine's standing no-payment note.
