The money for Restack is kindly provided by the European Commission's DG CNECT.

The first and primary objective of Restack is to provide an agile, effective and low-threshold funding mechanism to enable individual researchers and developers, as well as small (potentially distributed) teams of them, to research and develop important new ideas that help establish a robust and scalable Open Internet Stack. It shares this goal with its predecessors NGI0 PET, NGI0 Discovery, NGI0 Entrust and NGI0 Core and NGI0 Commons Fund. For more info about these programmes, please check https://nlnet.nl/NGI0.

Our humble mission is to enable the best people to work - by themselves and together - on their most relevant ideas in the best possible way, using short non-bureaucratic funding cycles and to iteratively mature the most promising ideas through an elaborate 'pipeline' of supporting activities that live up to high standards (sometimes called 'walk the talk') in terms of security, privacy, accessibility, open source licensing, standardisation, etc.

Review Committee

NLnet has installed a Review Committee for Restack. This Review Committe consists of independent experts from the internet and open source field, academia and the public sector. The committee is appointed for a period of one year, with the possiblity of renewal. The committee receives no remuneration for its work, and its members have no other economic interests with any projects funded by NGI0.

The Review Commitee receives the outcome of the selection process, and independently validates that all the projects that are selected are indeed eligible for funding, budgets are frugal, and that there are no other concerns.
