Aeternity themselves are working to build a layer of core Aepps for network launch. This is a really interesting approach and can be seen as a way to kickstart the network with some utility from the start. Alot of blockchains launch to a tiny number of transactions per day, this could help avoid that for Aeternity. It’s an opposite approach from the Ethereum Foundation who have opted to focus primarily on the protocol infrastructure (although they do give grants to higher level projects, e.g. Balance & ENS)
