Questions from today from chat:

Q: In your example of 3 Apps you have now, each App has its own Sourcechain, DNA etc.?
A: Each DNA has its own chain, a hApp is a set of DNAs

Q: Can DHTs be reused or built on? For example, an app evolves but can use and build on an earlier DHT?
A: Totally

Q: I’ve seen often the term “sharding”; does anyone have a definition of that?
A: basically it’s the concept of a tweet being stored only on 25 nodes, as opposed to all the nodes, A sharded DHT is a DHT in which not all the nodes hold all the data

Q: So DNAs are the interface for users to create blocks on for source chain?
A: yes but more importantly they define the validation rules

Q: will the hApps slows down a device more than a regular app?
A: in my PC it uses like 1% of CPU (or less)

Q: Wouldn’t that be bad for SEO etc if the App are web apps. My users go offline, my hosting is offline, I’m then dropped from Google for Example
A: well, actually SEO assumes “web accessible” apps, which means Holo – normal holochain apps are not accessible through a URL, only Holo enabled apps

Q: is every user an agent?
A: yes

Q: Are there any live Holochain applications at the minute or are we waiting on Elemental chat, Docusign & Junto?
A: we have been playing in small testnet for months. but they are not accessible from a URL, so if you refer to that, yes that’s Holo and elemental-chat
