Details

One of two NLnet calls open at the time of this fetch while the foundation transitions its regular open call to an Open Internet Stack effort. Eligible activities are broad: research, FOSS and open hardware development, security audits and formal proofs, documentation, standardisation, usability work, packaging, event travel, project management and infrastructure out-of-pocket costs. NLnet says it will contact applicants within a few days after each deadline, which is an acknowledgement rather than a decision, so decisionDays is left null.
