A first service would be the Lighthouse project which is supposed to be a
decentralized way of raising funds Kickstarter-style but which is
already limited by the 1MB block size cap (see
https://www.vinumeris.com/lighthouse/faq#max-pledges). Having a 1MB block size limit hinders innovation and tech development in my view
Excellent point I never thought of. This is a perfect example of how having a 1MB cap hurts decentralization by limiting projects like lighthouse, open bazaar and twister.
The fact that lighthouse only can allow for 684 pledges with the possibility of up to 1k means that it is severely limited. Popular crowdfunding platforms will sometimes get 20-50k pledges for a fundraiser or project .
So I suppose a 20MB block will allow for up to 20k pledges with optimizations which is much better.
